+==========================
+
+Fixes since v1.6.2.1
+--------------------
+
+* A longstanding confusing description of what --pickaxe option of
+  git-diff does has been clarified in the documentation.
+
+* "git-blame -S" did not quite work near the commits that were given
+  on the command line correctly.
+
+* "git diff --pickaxe-regexp" did not count overlapping matches
+  correctly.
+
+* "git diff" did not feed files in work-tree representation to external
+  diff and textconv.
+
+* "git-fetch" in a repository that was not cloned from anywhere said
+  it cannot find 'origin', which was hard to understand for new people.
+
+* "git-format-patch --numbered-files --stdout" did not have to die of
+  incompatible options; it now simply ignores --numbered-files as no files
+  are produced anyway.
+
+* "git-ls-files --deleted" did not work well with GIT_DIR&GIT_WORK_TREE.
+
+* "git-read-tree A B C..." without -m option has been broken for a long
+  time.
+
+* git-send-email ignored --in-reply-to when --no-thread was given.
+
+* 'git-submodule add' did not tolerate extra slashes and ./ in the path it
+  accepted from the command line; it now is more lenient.
+
+* git-svn misbehaved when the project contained a path that began with
+  two dashes.
+
+* import-zips script (in contrib) did not compute the common directory
+  prefix correctly.
+
+* miscompilation of negated enum constants by old gcc (2.9) affected the
+  codepaths to spawn subprocesses.
+
+Many small documentation updates are included as well.

+
+ * A few codepaths picked up the first few bytes from an sha1[] by
+   casting the (char *) pointer to (int *); GCC 4.4 did not like this,
+   and aborted compilation.
+
+ * Some unlink(2) failures went undiagnosed.
+
+ * The "recursive" merge strategy misbehaved when faced rename/delete
+   conflicts while coming up with an intermediate merge base.
+
+ * The low-level merge algorithm did not handle a degenerate case of
+   merging a file with itself using itself as the common ancestor
+   gracefully.  It should produce the file itself, but instead
+   produced an empty result.
+
+ * GIT_TRACE mechanism segfaulted when tracing a shell-quoted aliases.
+
+ * OpenBSD also uses st_ctimspec in "struct stat", instead of "st_ctim".
+
+ * With NO_CROSS_DIRECTORY_HARDLINKS, "make install" can be told not to
+   create hardlinks between $(gitexecdir)/git-$builtin_commands and
+   $(bindir)/git.
+
+ * command completion code in bash did not reliably detect that we are
+   in a bare repository.
+
+ * "git add ." in an empty directory complained that pathspec "." did not
+   match anything, which may be technically correct, but not useful.  We
+   silently make it a no-op now.
+
+ * "git add -p" (and "patch" action in "git add -i") was broken when
+   the first hunk that adds a line at the top was split into two and
+   both halves are marked to be used.
+
+ * "git blame path" misbehaved at the commit where path became file
+   from a directory with some files in it.
+
+ * "git for-each-ref" had a segfaulting bug when dealing with a tag object
+   created by an ancient git.
+
+ * "git format-patch -k" still added patch numbers if format.numbered
+   configuration was set.
+
+ * "git grep --color ''" did not terminate.  The command also had
+   subtle bugs with its -w option.
+
+ * http-push had a small use-after-free bug.
+
+ * "git push" was converting OFS_DELTA pack representation into less
+   efficient REF_DELTA representation unconditionally upon transfer,
+   making the transferred data unnecessarily larger.
+
+ * "git remote show origin" segfaulted when origin was still empty.
+
+Many other general usability updates around help text, diagnostic messages

+When the user does not tell "git push" what to push, it has always
+pushed matching refs.  For some people it is unexpected, and a new
+configuration variable push.default has been introduced to allow
+changing a different default behaviour.  To advertise the new feature,

 Updates since v1.6.2
 --------------------
 
 (subsystems)
 
+* various git-svn updates.
+
+* git-gui updates, including an update to Russian translation, and a
+  fix to an infinite loop when showing an empty diff.
+
+* gitk updates, including an update to Russian translation and improved Windows
+  support.
+
 (performance)
 
+* many uses of lstat(2) in the codepath for "git checkout" have been
+  optimized out.
+
 (usability, bells and whistles)
 
+* Boolean configuration variable yes/no can be written as on/off.
+
+* rsync:/path/to/repo can be used to run git over rsync for local
+  repositories.  It may not be useful in practice; meant primarily for
+  testing.
+
+* http transport learned to prompt and use password when fetching from or
+  pushing to http://user@host.xz/ URL.
+
+* (msysgit) progress output that is sent over the sideband protocol can
+  be handled appropriately in Windows console.
+
 * "--pretty=<style>" option to the log family of commands can now be
   spelled as "--format=<style>".  In addition, --format=%formatstring
   is a short-hand for --pretty=tformat:%formatstring.
 
-* "--oneline" is a synonym for "--pretty=oneline --abbrev=commit".
+* "--oneline" is a synonym for "--pretty=oneline --abbrev-commit".
+
+* "--graph" to the "git log" family can draw the commit ancestry graph
+  in colors.
 
 * If you realize that you botched the patch when you are editing hunks

+------------------
+
+ * An unquoted value in the configuration file, when it contains more than
+   one whitespaces in a row, got them replaced with a single space.
+
+ * "git am" used to accept a single piece of e-mail per file (not a mbox)
+   as its input, but multiple input format support in v1.6.4 broke it.
+   Apparently many people have been depending on this feature.
+
+ * The short help text for "git filter-branch" command was a single long
+   line, wrapped by terminals, and was hard to read.
+
+ * The "recursive" strategy of "git merge" segfaulted when a merge has
+   more than one merge-bases, and merging of these merge-bases involves
+   a rename/rename or a rename/add conflict.
+
+ * "git pull --rebase" did not use the right fork point when the
+   repository has already fetched from the upstream that rewinds the
+   branch it is based on in an earlier fetch.
+
+ * Explain the concept of fast-forward more fully in "git push"
+   documentation, and hint to refer to it from an error message when the
+   command refuses an update to protect the user.
+
+ * The default value for pack.deltacachesize, used by "git repack", is now
+   256M, instead of unbounded.  Otherwise a repack of a moderately sized
+   repository would needlessly eat into swap.
+
+ * Document how "git repack" (hence "git gc") interacts with a repository
+   that borrows its objects from other repositories (e.g. ones created by
+   "git clone -s").
+
+ * "git show" on an annotated tag lacked a delimiting blank line between
+   the tag itself and the contents of the object it tags.
+
+ * "git verify-pack -v" erroneously reported number of objects with too
+   deep delta depths as "chain length 0" objects.
+
+ * Long names of authors and committers outside US-ASCII were sometimes
+   incorrectly shown in "gitweb".
+
+Other minor documentation updates are included.

+GIT v1.6.4 Release Notes
+========================
+
+With the next major release, "git push" into a branch that is
+currently checked out will be refused by default.  You can choose
+what should happen upon such a push by setting the configuration
+variable receive.denyCurrentBranch in the receiving repository.
+
+To ease the transition plan, the receiving repository of such a
+push running this release will issue a big warning when the
+configuration variable is missing.  Please refer to:
+
+  http://git.or.cz/gitwiki/GitFaq#non-bare
+  http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
+
+for more details on the reason why this change is needed and the
+transition plan.
+
+For a similar reason, "git push $there :$killed" to delete the branch
+$killed in a remote repository $there, if $killed branch is the current
+branch pointed at by its HEAD, gets a large warning.  You can choose what
+should happen upon such a push by setting the configuration variable
+receive.denyDeleteCurrent in the receiving repository.
+
+
+Updates since v1.6.3
+--------------------
+
+(subsystems)
+
+ * gitweb Perl style clean-up.
+
+ * git-svn updates, including a new --authors-prog option to map author
+   names by invoking an external program, 'git svn reset' to unwind
+   'git svn fetch', support for more than one branches, documenting
+   of the useful --minimize-url feature, new "git svn gc" command, etc.
+
+(portability)
+
+ * We feed iconv with "UTF-8" instead of "utf8"; the former is
+   understood more widely.  Similarly updated test scripts to use
+   encoding names more widely understood (e.g. use "ISO8859-1" instead
+   of "ISO-8859-1").
+
+ * Various portability fixes/workarounds for different vintages of
+   SunOS, IRIX, and Windows.
+
+ * Git-over-ssh transport on Windows supports PuTTY plink and TortoisePlink.
+
+(performance)
+
+ * Many repeated use of lstat() are optimized out in "checkout" codepath.
+
+ * git-status (and underlying git-diff-index --cached) are optimized
+   to take advantage of cache-tree information in the index.
+
+(usability, bells and whistles)
+
+ * "git add --edit" lets users edit the whole patch text to fine-tune what
+   is added to the index.
+
+ * "git am" accepts StGIT series file as its input.
+
+ * "git bisect skip" skips to a more randomly chosen place in the hope
+   to avoid testing a commit that is too close to a commit that is
+   already known to be untestable.
+
+ * "git cvsexportcommit" learned -k option to stop CVS keywords expansion
+
+ * "git fast-export" learned to handle history simplification more
+   gracefully.
+
+ * "git fast-export" learned an option --tag-of-filtered-object to handle
+   dangling tags resulting from history simplification more usefully.
+
+ * "git grep" learned -p option to show the location of the match using the
+   same context hunk marker "git diff" uses.
+
+ * https transport can optionally be told that the used client
+   certificate is password protected, in which case it asks the
+   password only once.
+
+ * "git imap-send" is IPv6 aware.
+
+ * "git log --graph" draws graphs more compactly by using horizontal lines
+   when able.
+
+ * "git log --decorate" shows shorter refnames by stripping well-known
+   refs/* prefix.
+
+ * "git push $name" honors remote.$name.pushurl if present before
+   using remote.$name.url.  In other words, the URL used for fetching
+   and pushing can be different.
+
+ * "git send-email" understands quoted aliases in .mailrc files (might
+   have to be backported to 1.6.3.X).
+
+ * "git send-email" can fetch the sender address from the configuration
+   variable "sendmail.from" (and "sendmail.<identity>.from").
+
+ * "git show-branch" can color its output.
+
+ * "add" and "update" subcommands to "git submodule" learned --reference
+   option to use local clone with references.
+
+ * "git submodule update" learned --rebase option to update checked
+   out submodules by rebasing the local changes.
+
+ * "gitweb" can optionally use gravatar to adorn author/committer names.
+
+(developers)
+
+ * A major part of the "git bisect" wrapper has moved to C.
+
+ * Formatting with the new version of AsciiDoc 8.4.1 is now supported.
+
+Fixes since v1.6.3
+------------------
+
+All of the fixes in v1.6.3.X maintenance series are included in this
+release, unless otherwise noted.
+
+Here are fixes that this release has, but have not been backported to
+v1.6.3.X series.
+
+ * "git diff-tree -r -t" used to omit new or removed directories from
+   the output.  df533f3 (diff-tree -r -t: include added/removed
+   directories in the output, 2009-06-13) may need to be cherry-picked
+   to backport this fix.
+
+ * The way Git.pm sets up a Repository object was not friendly to callers
+   that chdir around.  It now internally records the repository location
+   as an absolute path when autodetected.
+
+ * Removing a section with "git config --remove-section", when its
+   section header has a variable definition on the same line, lost
+   that variable definition.
+
+ * "git rebase -p --onto" used to always leave side branches of a merge
+   intact, even when both branches are subject to rewriting.
+
+ * "git repack" used to faithfully follow grafts and considered true
+   parents recorded in the commit object unreachable from the commit.
+   After such a repacking, you cannot remove grafts without corrupting
+   the repository.
+
+ * "git send-email" did not detect erroneous loops in alias expansion.

+
+ * In configuration files, a few variables that name paths can begin with

+   unnecessarily before it freed.
+
+ * "git diff -B" and "git diff --dirstat" was not counting newly added

+ * "git format-patch revisions... -- path" issued an incorrect error

+==========================

+--------------------
+
+ * "git add -p" had a regression since v1.6.5.3 that broke deletion of

+
+ * "git archive -o o.zip -- Makefile" produced an archive in o.zip
+   but in POSIX tar format.
+

+
+ * Error messages given by "git merge" when the merge resulted in a
+   fast-forward still were in plumbing lingo, even though in v1.6.5
+   we reworded messages in other cases.
+
+ * The post-upload-hook run by upload-pack in response to "git fetch" has
+   been removed, due to security concerns (the hook first appeared in
+   1.6.5).

+GIT v1.6.5 Release Notes
+========================
+
+In git 1.7.0, which was planned to be the release after 1.6.5, "git
+push" into a branch that is currently checked out will be refused by
+default.
+
+You can choose what should happen upon such a push by setting the
+configuration variable receive.denyCurrentBranch in the receiving
+repository.
+
+Also, "git push $there :$killed" to delete the branch $killed in a remote
+repository $there, when $killed branch is the current branch pointed at by
+its HEAD, will be refused by default.
+
+You can choose what should happen upon such a push by setting the
+configuration variable receive.denyDeleteCurrent in the receiving
+repository.
+
+To ease the transition plan, the receiving repository of such a
+push running this release will issue a big warning when the
+configuration variable is missing.  Please refer to:
+
+  http://git.or.cz/gitwiki/GitFaq#non-bare
+  http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
+
+for more details on the reason why this change is needed and the
+transition plan.
+
+Updates since v1.6.4
+--------------------
+
+(subsystems)
+
+ * various updates to gitk, git-svn and gitweb.
+
+(portability)
+
+ * more improvements on mingw port.
+
+ * mingw will also give FRSX as the default value for the LESS
+   environment variable when the user does not have one.
+
+ * initial support to compile git on Windows with MSVC.
+
+(performance)
+
+ * On major platforms, the system can be compiled to use with Linus's
+   block-sha1 implementation of the SHA-1 hash algorithm, which
+   outperforms the default fallback implementation we borrowed from
+   Mozilla.
+
+ * Unnecessary inefficiency in deepening of a shallow repository has
+   been removed.
+
+ * "git clone" does not grab objects that it does not need (i.e.
+   referenced only from refs outside refs/heads and refs/tags
+   hierarchy) anymore.
+
+ * The "git" main binary used to link with libcurl, which then dragged
+   in a large number of external libraries.  When using basic plumbing
+   commands in scripts, this unnecessarily slowed things down.  We now
+   implement http/https/ftp transfer as a separate executable as we
+   used to.
+
+ * "git clone" run locally hardlinks or copies the files in .git/ to
+   newly created repository.  It used to give new mtime to copied files,
+   but this delayed garbage collection to trigger unnecessarily in the
+   cloned repository.  We now preserve mtime for these files to avoid
+   this issue.
+
+(usability, bells and whistles)
+
+ * Human writable date format to various options, e.g. --since=yesterday,
+   master@{2000.09.17}, are taught to infer some omitted input properly.
+
+ * A few programs gave verbose "advice" messages to help uninitiated
+   people when issuing error messages.  An infrastructure to allow
+   users to squelch them has been introduced, and a few such messages
+   can be silenced now.
+
+ * refs/replace/ hierarchy is designed to be usable as a replacement
+   of the "grafts" mechanism, with the added advantage that it can be
+   transferred across repositories.
+
+ * "git am" learned to optionally ignore whitespace differences.
+
+ * "git am" handles input e-mail files that has CRLF line endings sensibly.
+
+ * "git am" learned "--scissors" option to allow you to discard early part
+   of an incoming e-mail.
+
+ * "git archive -o output.zip" works without being told what format to
+   use with an explicit "--format=zip".option.
+
+ * "git checkout", "git reset" and "git stash" learned to pick and
+   choose to use selected changes you made, similar to "git add -p".
+
+ * "git clone" learned a "-b" option to pick a HEAD to check out
+   different from the remote's default branch.
+
+ * "git clone" learned --recursive option.
+
+ * "git clone" from a local repository on a different filesystem used to
+   copy individual object files without preserving the old timestamp, giving
+   them extra lifetime in the new repository until they gc'ed.
+
+ * "git commit --dry-run $args" is a new recommended way to ask "what would
+   happen if I try to commit with these arguments."
+
+ * "git commit --dry-run" and "git status" shows conflicted paths in a
+   separate section to make them easier to spot during a merge.
+
+ * "git cvsimport" now supports password-protected pserver access even
+   when the password is not taken from ~/.cvspass file.
+
+ * "git fast-export" learned --no-data option that can be useful when
+   reordering commits and trees without touching the contents of
+   blobs.
+
+ * "git fast-import" has a pair of new front-end in contrib/ area.
+
+ * "git init" learned to mkdir/chdir into a directory when given an
+   extra argument (i.e. "git init this").
+
+ * "git instaweb" optionally can use mongoose as the web server.
+
+ * "git log --decorate" can optionally be told with --decorate=full to
+   give the reference name in full.
+
+ * "git merge" issued an unnecessarily scary message when it detected
+   that the merge may have to touch the path that the user has local
+   uncommitted changes to. The message has been reworded to make it
+   clear that the command aborted, without doing any harm.
+
+ * "git push" can be told to be --quiet.
+
+ * "git push" pays attention to url.$base.pushInsteadOf and uses a URL
+   that is derived from the URL used for fetching.
+
+ * informational output from "git reset" that lists the locally modified
+   paths is made consistent with that of "git checkout $another_branch".
+
+ * "git submodule" learned to give submodule name to scripts run with
+   "foreach" subcommand.
+
+ * various subcommands to "git submodule" learned --recursive option.
+
+ * "git submodule summary" learned --files option to compare the work
+   tree vs the commit bound at submodule path, instead of comparing
+   the index.
+
+ * "git upload-pack", which is the server side support for "git clone" and
+   "git fetch", can call a new post-upload-pack hook for statistics purposes.
+
+(developers)
+
+ * With GIT_TEST_OPTS="--root=/p/a/t/h", tests can be run outside the
+   source directory; using tmpfs may give faster turnaround.
+
+ * With NO_PERL_MAKEMAKER set, DESTDIR= is now honoured, so you can
+   build for one location, and install into another location to tar it
+   up.
+
+Fixes since v1.6.4
+------------------
+
+All of the fixes in v1.6.4.X maintenance series are included in this
+release, unless otherwise noted.

+Git v1.6.6 Release Notes
+========================
+
+Notes on behaviour change
+-------------------------
+
+ * In this release, "git fsck" defaults to "git fsck --full" and
+   checks packfiles, and because of this it will take much longer to
+   complete than before.  If you prefer a quicker check only on loose
+   objects (the old default), you can say "git fsck --no-full".  This
+   has been supported by 1.5.4 and newer versions of git, so it is
+   safe to write it in your script even if you use slightly older git
+   on some of your machines.
+
+Preparing yourselves for compatibility issues in 1.7.0
+------------------------------------------------------
+
+In git 1.7.0, which is planned to be the release after 1.6.6, there will
+be a handful of behaviour changes that will break backward compatibility.
+
+These changes were discussed long time ago and existing behaviours have
+been identified as more problematic to the userbase than keeping them for
+the sake of backward compatibility.
+
+When necessary, a transition strategy for existing users has been designed
+not to force them running around setting configuration variables and
+updating their scripts in order to either keep the traditional behaviour
+or adjust to the new behaviour, on the day their sysadmin decides to install
+the new version of git.  When we switched from "git-foo" to "git foo" in
+1.6.0, even though the change had been advertised and the transition
+guide had been provided for a very long time, the users procrastinated
+during the entire transtion period, and ended up panicking on the day
+their sysadmins updated their git installation.  We are trying to avoid
+repeating that unpleasantness in the 1.7.0 release.
+
+For changes decided to be in 1.7.0, commands that will be affected
+have been much louder to strongly discourage such procrastination, and
+they continue to be in this release.  If you have been using recent
+versions of git, you would have seen warnings issued when you used
+features whose behaviour will change, with a clear instruction on how
+to keep the existing behaviour if you want to.  You hopefully are
+already well prepared.
+
+Of course, we have also been giving "this and that will change in
+1.7.0; prepare yourselves" warnings in the release notes and
+announcement messages for the past few releases.  Let's see how well
+users will fare this time.
+
+ * "git push" into a branch that is currently checked out (i.e. pointed by
+   HEAD in a repository that is not bare) will be refused by default.
+
+   Similarly, "git push $there :$killed" to delete the branch $killed
+   in a remote repository $there, when $killed branch is the current
+   branch pointed at by its HEAD, will be refused by default.
+
+   Setting the configuration variables receive.denyCurrentBranch and
+   receive.denyDeleteCurrent to 'ignore' in the receiving repository
+   can be used to override these safety features.  Versions of git
+   since 1.6.2 have issued a loud warning when you tried to do these
+   operations without setting the configuration, so repositories of
+   people who still need to be able to perform such a push should
+   already have been future proofed.
+
+   Please refer to:
+
+   http://git.or.cz/gitwiki/GitFaq#non-bare
+   http://thread.gmane.org/gmane.comp.version-control.git/107758/focus=108007
+
+   for more details on the reason why this change is needed and the
+   transition process that already took place so far.
+
+ * "git send-email" will not make deep threads by default when sending a
+   patch series with more than two messages.  All messages will be sent
+   as a reply to the first message, i.e. cover letter.  Git 1.6.6 (this
+   release) will issue a warning about the upcoming default change, when
+   it uses the traditional "deep threading" behaviour as the built-in
+   default.  To squelch the warning but still use the "deep threading"
+   behaviour, give --chain-reply-to option or set sendemail.chainreplyto
+   to true.
+
+   It has been possible to configure send-email to send "shallow thread"
+   by setting sendemail.chainreplyto configuration variable to false.
+   The only thing 1.7.0 release will do is to change the default when
+   you haven't configured that variable.
+
+ * "git status" will not be "git commit --dry-run".  This change does not
+   affect you if you run the command without pathspec.
+
+   Nobody sane found the current behaviour of "git status Makefile" useful
+   nor meaningful, and it confused users.  "git commit --dry-run" has been
+   provided as a way to get the current behaviour of this command since
+   1.6.5.
+
+ * "git diff" traditionally treated various "ignore whitespace" options
+   only as a way to filter the patch output.  "git diff --exit-code -b"
+   exited with non-zero status even if all changes were about changing the
+   ammount of whitespace and nothing else.  and "git diff -b" showed the
+   "diff --git" header line for such a change without patch text.
+
+   In 1.7.0, the "ignore whitespaces" will affect the semantics of the
+   diff operation itself.  A change that does not affect anything but
+   whitespaces will be reported with zero exit status when run with
+   --exit-code, and there will not be "diff --git" header for such a
+   change.
+
+
+Updates since v1.6.5
+--------------------
+
+(subsystems)
+
+ * various gitk updates including use of themed widgets under Tk 8.5,
+   Japanese translation, a fix to a bug when running "gui blame" from
+   a subdirectory, etc.
+
+ * various git-gui updates including new translations, wm states fixes,
+   Tk bug workaround after quitting, improved heuristics to trigger gc,
+   etc.
+
+ * various git-svn updates.
+
+ * "git fetch" over http learned a new mode that is different from the
+   traditional "dumb commit walker".
+
+(portability)
+
+ * imap-send can be built on mingw port.
+
+(performance)
+
+ * "git diff -B" has smaller memory footprint.
+
+(usability, bells and whistles)
+
+ * The object replace mechanism can be bypassed with --no-replace-objects
+   global option given to the "git" program.
+
+ * In configuration files, a few variables that name paths can begin with ~/
+   and ~username/ and they are expanded as expected.
+
+ * "git subcmd -h" now shows short usage help for many more subcommands.
+
+ * "git bisect reset" can reset to an arbitrary commit.
+
+ * "git checkout frotz" when there is no local branch "frotz" but there
+   is only one remote tracking branch "frotz" is taken as a request to
+   start the named branch at the corresponding remote tracking branch.
+
+ * "git commit -c/-C/--amend" can be told with a new "--reset-author" option
+   to ignore authorship information in the commit it is taking the message
+   from.
+
+ * "git describe" can be told to add "-dirty" suffix with "--dirty" option.
+
+ * "git diff" learned --submodule option to show a list of one-line logs
+   instead of differences between the commit object names.
+
+ * "git diff" learned to honor diff.color.func configuration to paint
+   function name hint printed on the hunk header "@@ -j,k +l,m @@" line
+   in the specified color.
+
+ * "git fetch" learned --all and --multiple options, to run fetch from
+   many repositories, and --prune option to remove remote tracking
+   branches that went stale.  These make "git remote update" and "git
+   remote prune" less necessary (there is no plan to remove "remote
+   update" nor "remote prune", though).
+
+ * "git fsck" by default checks the packfiles (i.e. "--full" is the
+   default); you can turn it off with "git fsck --no-full".
+
+ * "git grep" can use -F (fixed strings) and -i (ignore case) together.
+
+ * import-tars contributed fast-import frontend learned more types of
+   compressed tarballs.
+
+ * "git instaweb" knows how to talk with mod_cgid to apache2.
+
+ * "git log --decorate" shows the location of HEAD as well.
+
+ * "git log" and "git rev-list" learned to take revs and pathspecs from
+   the standard input with the new "--stdin" option.
+
+ * "--pretty=format" option to "log" family of commands learned:
+
+   . to wrap text with the "%w()" specifier.
+   . to show reflog information with "%g[sdD]" specifier.
+
+ * "git notes" command to annotate existing commits.
+
+ * "git merge" (and "git pull") learned --ff-only option to make it fail
+   if the merge does not result in a fast-forward.
+
+ * "git mergetool" learned to use p4merge.
+
+ * "git rebase -i" learned "reword" that acts like "edit" but immediately
+   starts an editor to tweak the log message without returning control to
+   the shell, which is done by "edit" to give an opportunity to tweak the
+   contents.
+
+ * "git send-email" can be told with "--envelope-sender=auto" to use the
+   same address as "From:" address as the envelope sender address.
+
+ * "git send-email" will issue a warning when it defaults to the
+   --chain-reply-to behaviour without being told by the user and
+   instructs to prepare for the change of the default in 1.7.0 release.
+
+ * In "git submodule add <repository> <path>", <path> is now optional and
+   inferred from <repository> the same way "git clone <repository>" does.
+
+ * "git svn" learned to read SVN 1.5+ and SVK merge tickets.
+
+ * "git svn" learned to recreate empty directories tracked only by SVN.
+
+ * "gitweb" can optionally render its "blame" output incrementally (this
+   requires JavaScript on the client side).
+
+ * Author names shown in gitweb output are links to search commits by the
+   author.
+
+Fixes since v1.6.5

+All of the fixes in v1.6.5.X maintenance series are included in this

+Git v1.7.0.2 Release Notes
+==========================
+
+Fixes since v1.7.0.1
+--------------------
+
+ * GIT_PAGER was not honored consistently by some scripted Porcelains, most
+   notably "git am".
+
+ * updating working tree files after telling git to add them to the
+   index and while it is still working created garbage object files in
+   the repository without diagnosing it as an error.
+
+ * "git bisect -- pathspec..." did not diagnose an error condition properly when
+   the simplification with given pathspec made the history empty.
+
+ * "git rev-list --cherry-pick A...B" now has an obvious optimization when the
+   histories haven't diverged (i.e. when one end is an ancestor of the other).
+
+ * "git diff --quiet -w" did not work as expected.
+
+ * "git fast-import" didn't work with a large input, as it lacked support
+   for producing the pack index in v2 format.
+
+ * "git imap-send" didn't use CRLF line endings over the imap protocol
+   when storing its payload to the draft box, violating RFC 3501.
+
+ * "git log --format='%w(x,y,z)%b'" and friends that rewrap message
+   has been optimized for utf-8 payload.
+
+ * Error messages generated on the receiving end did not come back to "git
+   push".
+
+ * "git status" in 1.7.0 lacked the optimization we used to have in 1.6.X series
+   to speed up scanning of large working tree.
+
+ * "gitweb" did not diagnose parsing errors properly while reading tis configuration
+   file.
+
+And other minor fixes and documentation updates.

+Git v1.7.0 Release Notes
+========================
+
+Notes on behaviour change
+-------------------------
+
+ * "git push" into a branch that is currently checked out (i.e. pointed at by
+   HEAD in a repository that is not bare) is refused by default.
+
+   Similarly, "git push $there :$killed" to delete the branch $killed
+   in a remote repository $there, when $killed branch is the current
+   branch pointed at by its HEAD, will be refused by default.
+
+   Setting the configuration variables receive.denyCurrentBranch and
+   receive.denyDeleteCurrent to 'ignore' in the receiving repository
+   can be used to override these safety features.
+
+ * "git send-email" does not make deep threads by default when sending a
+   patch series with more than two messages.  All messages will be sent
+   as a reply to the first message, i.e. cover letter.
+
+   It has been possible already to configure send-email to send "shallow thread"
+   by setting sendemail.chainreplyto configuration variable to false.  The
+   only thing this release does is to change the default when you haven't
+   configured that variable.
+
+ * "git status" is not "git commit --dry-run" anymore.  This change does
+   not affect you if you run the command without argument.
+
+ * "git diff" traditionally treated various "ignore whitespace" options
+   only as a way to filter the patch output.  "git diff --exit-code -b"
+   exited with non-zero status even if all changes were about changing the
+   amount of whitespace and nothing else;  and "git diff -b" showed the
+   "diff --git" header line for such a change without patch text.
+
+   In this release, the "ignore whitespaces" options affect the semantics
+   of the diff operation.  A change that does not affect anything but
+   whitespaces is reported with zero exit status when run with
+   --exit-code, and there is no "diff --git" header for such a change.
+
+ * External diff and textconv helpers are now executed using the shell.
+   This makes them consistent with other programs executed by git, and
+   allows you to pass command-line parameters to the helpers. Any helper
+   paths containing spaces or other metacharacters now need to be
+   shell-quoted.  The affected helpers are GIT_EXTERNAL_DIFF in the
+   environment, and diff.*.command and diff.*.textconv in the config
+   file.
+
+ * The --max-pack-size argument to 'git repack', 'git pack-objects', and
+   'git fast-import' was assuming the provided size to be expressed in MiB,
+   unlike the corresponding config variable and other similar options accepting
+   a size value.  It is now expecting a size expressed in bytes, with a possible
+   unit suffix of 'k', 'm', or 'g'.
+
+Updates since v1.6.6
+--------------------
+
+(subsystems)
+
+ * "git fast-import" updates; adds "option" and "feature" to detect the
+   mismatch between fast-import and the frontends that produce the input
+   stream.
+
+ * "git svn" support of subversion "merge tickets" and miscellaneous fixes.
+
+ * "gitk" and "git gui" translation updates.
+
+ * "gitweb" updates (code clean-up, load checking etc.)
+
+(portability)
+
+ * Some more MSVC portability patches for msysgit port.
+
+ * Minimum Pthreads emulation for msysgit port.
+
+(performance)
+
+ * More performance improvement patches for msysgit port.
+
+(usability, bells and whistles)
+
+ * More commands learned "--quiet" and "--[no-]progress" options.
+
+ * Various commands given by the end user (e.g. diff.type.textconv,
+   and GIT_EDITOR) can be specified with command line arguments.  E.g. it
+   is now possible to say "[diff "utf8doc"] textconv = nkf -w".
+
+ * "sparse checkout" feature allows only part of the work tree to be
+   checked out.
+
+ * HTTP transfer can use authentication scheme other than basic
+   (i.e./e.g. digest).
+
+ * Switching from a version of superproject that used to have a submodule
+   to another version of superproject that no longer has it did not remove
+   the submodule directory when it should (namely, when you are not
+   interested in the submodule at all and didn't clone/checkout).
+
+ * A new attribute conflict-marker-size can be used to change the size of
+   the conflict markers from the default 7; this is useful when tracked
+   contents (e.g. git-merge documentation) have strings that resemble the
+   conflict markers.
+
+ * A new syntax "<branch>@{upstream}" can be used on the command line to
+   substitute the name of the "upstream" of the branch.  Missing branch
+   defaults to the current branch, so "git fetch && git merge @{upstream}"
+   will be equivalent to "git pull".
+
+ * "git am --resolved" has a synonym "git am --continue".
+
+ * "git branch --set-upstream" can be used to update the (surprise!) upstream,
+   i.e. where the branch is supposed to pull and merge from (or rebase onto).
+
+ * "git checkout A...B" is a way to detach HEAD at the merge base between
+   A and B.
+
+ * "git checkout -m path" to reset the work tree file back into the
+   conflicted state works even when you already ran "git add path" and
+   resolved the conflicts.
+
+ * "git commit --date='<date>'" can be used to override the author date
+   just like "git commit --author='<name> <email>'" can be used to
+   override the author identity.
+
+ * "git commit --no-status" can be used to omit the listing of the index
+   and the work tree status in the editor used to prepare the log message.
+
+ * "git commit" warns a bit more aggressively until you configure user.email,
+   whose default value almost always is not (and fundamentally cannot be)
+   what you want.
+
+ * "git difftool" has been extended to make it easier to integrate it
+   with gitk.
+
+ * "git fetch --all" can now be used in place of "git remote update".
+
+ * "git grep" does not rely on external grep anymore.  It can use more than
+   one thread to accelerate the operation.
+
+ * "git grep" learned "--quiet" option.
+
+ * "git log" and friends learned "--glob=heads/*" syntax that is a more
+   flexible way to complement "--branches/--tags/--remotes".
+
+ * "git merge" learned to pass options specific to strategy-backends.  E.g.
+
+    - "git merge -Xsubtree=path/to/directory" can be used to tell the subtree
+      strategy how much to shift the trees explicitly.
+
+    - "git merge -Xtheirs" can be used to auto-merge as much as possible,
+      while discarding your own changes and taking merged version in
+      conflicted regions.
+
+ * "git push" learned "git push origin --delete branch", a syntactic sugar
+   for "git push origin :branch".
+
+ * "git push" learned "git push --set-upstream origin forker:forkee" that
+   lets you configure your "forker" branch to later pull from "forkee"
+   branch at "origin".
+
+ * "git rebase --onto A...B" means the history is replayed on top of the
+   merge base between A and B.
+
+ * "git rebase -i" learned new action "fixup" that squashes the change
+   but does not affect existing log message.
+
+ * "git rebase -i" also learned --autosquash option that is useful
+   together with the new "fixup" action.
+
+ * "git remote" learned set-url subcommand that updates (surprise!) url
+   for an existing remote nickname.
+
+ * "git rerere" learned "forget path" subcommand.  Together with "git
+   checkout -m path" it will be useful when you recorded a wrong
+   resolution.
+
+ * Use of "git reset --merge" has become easier when resetting away a
+   conflicted mess left in the work tree.
+
+ * "git rerere" had rerere.autoupdate configuration but there was no way
+   to countermand it from the command line; --no-rerere-autoupdate option
+   given to "merge", "revert", etc. fixes this.
+
+ * "git status" learned "-s(hort)" output format.
+
+(developers)
+
+ * The infrastructure to build foreign SCM interface has been updated.
+
+ * Many more commands are now built-in.
+
+ * THREADED_DELTA_SEARCH is no more.  If you build with threads, delta
+   compression will always take advantage of it.
+
+Fixes since v1.6.6
+------------------
+
+All of the fixes in v1.6.6.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git branch -d branch" used to refuse deleting the branch even when
+   the branch is fully merged to its upstream branch if it is not merged
+   to the current branch.  It now deletes it in such a case.
+
+ * "fiter-branch" command incorrectly said --prune-empty and --filter-commit
+   were incompatible; the latter should be read as --commit-filter.
+
+ * When using "git status" or asking "git diff" to compare the work tree
+   with something, they used to consider that a checked-out submodule with
+   uncommitted changes is not modified; this could cause people to forget
+   committing these changes in the submodule before committing in the
+   superproject. They now consider such a change as a modification and
+   "git diff" will append a "-dirty" to the work tree side when generating
+   patch output or when used with the --submodule option.

+Fighting regressions with git bisect
+====================================
+:Author: Christian Couder
+:Email: chriscool@tuxfamily.org
+:Date: 2009/11/08
+
+Abstract
+--------
+
+"git bisect" enables software users and developers to easily find the
+commit that introduced a regression. We show why it is important to
+have good tools to fight regressions. We describe how "git bisect"
+works from the outside and the algorithms it uses inside. Then we
+explain how to take advantage of "git bisect" to improve current
+practices. And we discuss how "git bisect" could improve in the
+future.
+
+
+Introduction to "git bisect"
+----------------------------
+
+Git is a Distributed Version Control system (DVCS) created by Linus
+Torvalds and maintained by Junio Hamano.
+
+In Git like in many other Version Control Systems (VCS), the different
+states of the data that is managed by the system are called
+commits. And, as VCS are mostly used to manage software source code,
+sometimes "interesting" changes of behavior in the software are
+introduced in some commits.
+
+In fact people are specially interested in commits that introduce a
+"bad" behavior, called a bug or a regression. They are interested in
+these commits because a commit (hopefully) contains a very small set
+of source code changes. And it's much easier to understand and
+properly fix a problem when you only need to check a very small set of
+changes, than when you don't know where look in the first place.
+
+So to help people find commits that introduce a "bad" behavior, the
+"git bisect" set of commands was invented. And it follows of course
+that in "git bisect" parlance, commits where the "interesting
+behavior" is present are called "bad" commits, while other commits are
+called "good" commits. And a commit that introduce the behavior we are
+interested in is called a "first bad commit". Note that there could be
+more than one "first bad commit" in the commit space we are searching.
+
+So "git bisect" is designed to help find a "first bad commit". And to
+be as efficient as possible, it tries to perform a binary search.
+
+
+Fighting regressions overview
+-----------------------------
+
+Regressions: a big problem
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Regressions are a big problem in the software industry. But it's
+difficult to put some real numbers behind that claim.
+
+There are some numbers about bugs in general, like a NIST study in
+2002 <<1>> that said:
+
+_____________
+Software bugs, or errors, are so prevalent and so detrimental that
+they cost the U.S. economy an estimated $59.5 billion annually, or
+about 0.6 percent of the gross domestic product, according to a newly
+released study commissioned by the Department of Commerce's National
+Institute of Standards and Technology (NIST). At the national level,
+over half of the costs are borne by software users and the remainder
+by software developers/vendors.  The study also found that, although
+all errors cannot be removed, more than a third of these costs, or an
+estimated $22.2 billion, could be eliminated by an improved testing
+infrastructure that enables earlier and more effective identification
+and removal of software defects. These are the savings associated with
+finding an increased percentage (but not 100 percent) of errors closer
+to the development stages in which they are introduced. Currently,
+over half of all errors are not found until "downstream" in the
+development process or during post-sale software use.
+_____________
+
+And then:
+
+_____________
+Software developers already spend approximately 80 percent of
+development costs on identifying and correcting defects, and yet few
+products of any type other than software are shipped with such high
+levels of errors.
+_____________
+
+Eventually the conclusion started with:
+
+_____________
+The path to higher software quality is significantly improved software
+testing.
+_____________
+
+There are other estimates saying that 80% of the cost related to
+software is about maintenance <<2>>.
+
+Though, according to Wikipedia <<3>>:
+
+_____________
+A common perception of maintenance is that it is merely fixing
+bugs. However, studies and surveys over the years have indicated that
+the majority, over 80%, of the maintenance effort is used for
+non-corrective actions (Pigosky 1997). This perception is perpetuated
+by users submitting problem reports that in reality are functionality
+enhancements to the system.
+_____________
+
+But we can guess that improving on existing software is very costly
+because you have to watch out for regressions. At least this would
+make the above studies consistent among themselves.
+
+Of course some kind of software is developed, then used during some
+time without being improved on much, and then finally thrown away. In
+this case, of course, regressions may not be a big problem. But on the
+other hand, there is a lot of big software that is continually
+developed and maintained during years or even tens of years by a lot
+of people. And as there are often many people who depend (sometimes
+critically) on such software, regressions are a really big problem.
+
+One such software is the linux kernel. And if we look at the linux
+kernel, we can see that a lot of time and effort is spent to fight
+regressions. The release cycle start with a 2 weeks long merge
+window. Then the first release candidate (rc) version is tagged. And
+after that about 7 or 8 more rc versions will appear with around one
+week between each of them, before the final release.
+
+The time between the first rc release and the final release is
+supposed to be used to test rc versions and fight bugs and especially
+regressions. And this time is more than 80% of the release cycle
+time. But this is not the end of the fight yet, as of course it
+continues after the release.
+
+And then this is what Ingo Molnar (a well known linux kernel
+developer) says about his use of git bisect:
+
+_____________
+I most actively use it during the merge window (when a lot of trees
+get merged upstream and when the influx of bugs is the highest) - and
+yes, there have been cases that i used it multiple times a day. My
+average is roughly once a day.
+_____________
+
+So regressions are fought all the time by developers, and indeed it is
+well known that bugs should be fixed as soon as possible, so as soon
+as they are found. That's why it is interesting to have good tools for
+this purpose.
+
+Other tools to fight regressions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+So what are the tools used to fight regressions? They are nearly the
+same as those used to fight regular bugs. The only specific tools are
+test suites and tools similar as "git bisect".
+
+Test suites are very nice. But when they are used alone, they are
+supposed to be used so that all the tests are checked after each
+commit. This means that they are not very efficient, because many
+tests are run for no interesting result, and they suffer from
+combinational explosion.
+
+In fact the problem is that big software often has many different
+configuration options and that each test case should pass for each
+configuration after each commit. So if you have for each release: N
+configurations, M commits and T test cases, you should perform:
+
+-------------
+N * M * T tests
+-------------
+
+where N, M and T are all growing with the size your software.
+
+So very soon it will not be possible to completely test everything.
+
+And if some bugs slip through your test suite, then you can add a test
+to your test suite. But if you want to use your new improved test
+suite to find where the bug slipped in, then you will either have to
+emulate a bisection process or you will perhaps bluntly test each
+commit backward starting from the "bad" commit you have which may be
+very wasteful.
+
+"git bisect" overview
+---------------------
+
+Starting a bisection
+~~~~~~~~~~~~~~~~~~~~
+
+The first "git bisect" subcommand to use is "git bisect start" to
+start the search. Then bounds must be set to limit the commit
+space. This is done usually by giving one "bad" and at least one
+"good" commit. They can be passed in the initial call to "git bisect
+start" like this:
+
+-------------
+$ git bisect start [BAD [GOOD...]]
+-------------
+
+or they can be set using:
+
+-------------
+$ git bisect bad [COMMIT]
+-------------
+
+and:
+
+-------------
+$ git bisect good [COMMIT...]
+-------------
+
+where BAD, GOOD and COMMIT are all names that can be resolved to a
+commit.
+
+Then "git bisect" will checkout a commit of its choosing and ask the
+user to test it, like this:
+
+-------------
+$ git bisect start v2.6.27 v2.6.25
+Bisecting: 10928 revisions left to test after this (roughly 14 steps)
+[2ec65f8b89ea003c27ff7723525a2ee335a2b393] x86: clean up using max_low_pfn on 32-bit
+-------------
+
+Note that the example that we will use is really a toy example, we
+will be looking for the first commit that has a version like
+"2.6.26-something", that is the commit that has a "SUBLEVEL = 26" line
+in the top level Makefile. This is a toy example because there are
+better ways to find this commit with git than using "git bisect" (for
+example "git blame" or "git log -S<string>").
+
+Driving a bisection manually
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+At this point there are basically 2 ways to drive the search. It can
+be driven manually by the user or it can be driven automatically by a
+script or a command.
+
+If the user is driving it, then at each step of the search, the user
+will have to test the current commit and say if it is "good" or "bad"
+using the "git bisect good" or "git bisect bad" commands respectively
+that have been described above. For example:
+
+-------------
+$ git bisect bad
+Bisecting: 5480 revisions left to test after this (roughly 13 steps)
+[66c0b394f08fd89236515c1c84485ea712a157be] KVM: kill file->f_count abuse in kvm
+-------------
+
+And after a few more steps like that, "git bisect" will eventually
+find a first bad commit:
+
+-------------
+$ git bisect bad
+2ddcca36c8bcfa251724fe342c8327451988be0d is the first bad commit

+Author: Linus Torvalds <torvalds@linux-foundation.org>
+Date:   Sat May 3 11:59:44 2008 -0700
+
+    Linux 2.6.26-rc1
+
+:100644 100644 5cf8258195331a4dbdddff08b8d68642638eea57 4492984efc09ab72ff6219a7bc21fb6a957c4cd5 M      Makefile
+bisect run success
+-------------
+
+In this example, we passed "grep '^SUBLEVEL = 25' Makefile" as
+parameter to "git bisect run". This means that at each step, the grep
+command we passed will be launched. And if it exits with code 0 (that
+means success) then git bisect will mark the current state as
+"good". If it exits with code 1 (or any code between 1 and 127
+included, except the special code 125), then the current state will be
+marked as "bad".
+
+Exit code between 128 and 255 are special to "git bisect run". They
+make it stop immediately the bisection process. This is useful for
+example if the command passed takes too long to complete, because you
+can kill it with a signal and it will stop the bisection process.
+
+It can also be useful in scripts passed to "git bisect run" to "exit
+255" if some very abnormal situation is detected.
+
+Avoiding untestable commits
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Sometimes it happens that the current state cannot be tested, for
+example if it does not compile because there was a bug preventing it
+at that time. This is what the special exit code 125 is for. It tells
+"git bisect run" that the current commit should be marked as
+untestable and that another one should be chosen and checked out.
+
+If the bisection process is driven manually, you can use "git bisect
+skip" to do the same thing. (In fact the special exit code 125 makes
+"git bisect run" use "git bisect skip" in the background.)
+
+Or if you want more control, you can inspect the current state using
+for example "git bisect visualize". It will launch gitk (or "git log"
+if the DISPLAY environment variable is not set) to help you find a
+better bisection point.
+
+Either way, if you have a string of untestable commits, it might
+happen that the regression you are looking for has been introduced by
+one of these untestable commits. In this case it's not possible to
+tell for sure which commit introduced the regression.
+
+So if you used "git bisect skip" (or the run script exited with
+special code 125) you could get a result like this:
+
+-------------
+There are only 'skip'ped commits left to test.
+The first bad commit could be any of:
+15722f2fa328eaba97022898a305ffc8172db6b1

+070eab2303024706f2924822bfec8b9847e4ac1b
+We cannot bisect more!
+-------------
+
+Saving a log and replaying it
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you want to show other people your bisection process, you can get a
+log using for example:
+
+-------------
+$ git bisect log > bisect_log.txt
+-------------
+
+And it is possible to replay it using:
+
+-------------
+$ git bisect replay bisect_log.txt
+-------------
+
+
+"git bisect" details
+--------------------
+
+Bisection algorithm
+~~~~~~~~~~~~~~~~~~~
+
+As the Git commits form a directed acyclic graph (DAG), finding the
+best bisection commit to test at each step is not so simple. Anyway
+Linus found and implemented a "truly stupid" algorithm, later improved
+by Junio Hamano, that works quite well.
+
+So the algorithm used by "git bisect" to find the best bisection
+commit when there are no skipped commits is the following:
+
+1) keep only the commits that:
+
+a) are ancestor of the "bad" commit (including the "bad" commit itself),
+b) are not ancestor of a "good" commit (excluding the "good" commits).
+
+This means that we get rid of the uninteresting commits in the DAG.
+
+For example if we start with a graph like this:
+
+-------------
+G-Y-G-W-W-W-X-X-X-X
+          \ /
+           W-W-B
+          /
+Y---G-W---W
+ \ /   \
+Y-Y     X-X-X-X
+
+-> time goes this way ->
+-------------
+
+where B is the "bad" commit, "G" are "good" commits and W, X, and Y
+are other commits, we will get the following graph after this first
+step:
+
+-------------
+W-W-W
+     \
+      W-W-B
+     /
+W---W
+-------------
+
+So only the W and B commits will be kept. Because commits X and Y will
+have been removed by rules a) and b) respectively, and because commits
+G are removed by rule b) too.
+
+Note for git users, that it is equivalent as keeping only the commit
+given by:
+
+-------------
+git rev-list BAD --not GOOD1 GOOD2...
+-------------
+
+Also note that we don't require the commits that are kept to be
+descendants of a "good" commit. So in the following example, commits W
+and Z will be kept:
+
+-------------
+G-W-W-W-B
+   /
+Z-Z
+-------------
+
+2) starting from the "good" ends of the graph, associate to each
+commit the number of ancestors it has plus one
+
+For example with the following graph where H is the "bad" commit and A
+and D are some parents of some "good" commits:
+
+-------------
+A-B-C
+     \
+      F-G-H
+     /
+D---E
+-------------
+
+this will give:
+
+-------------
+1 2 3
+A-B-C
+     \6 7 8
+      F-G-H
+1   2/
+D---E
+-------------
+
+3) associate to each commit: min(X, N - X)
+
+where X is the value associated to the commit in step 2) and N is the
+total number of commits in the graph.
+
+In the above example we have N = 8, so this will give:
+
+-------------
+1 2 3
+A-B-C
+     \2 1 0
+      F-G-H
+1   2/
+D---E
+-------------
+
+4) the best bisection point is the commit with the highest associated
+number
+
+So in the above example the best bisection point is commit C.
+
+5) note that some shortcuts are implemented to speed up the algorithm
+
+As we know N from the beginning, we know that min(X, N - X) can't be
+greater than N/2. So during steps 2) and 3), if we would associate N/2
+to a commit, then we know this is the best bisection point. So in this
+case we can just stop processing any other commit and return the
+current commit.
+
+Bisection algorithm debugging
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For any commit graph, you can see the number associated with each
+commit using "git rev-list --bisect-all".
+
+For example, for the above graph, a command like:
+
+-------------
+$ git rev-list --bisect-all BAD --not GOOD1 GOOD2
+-------------
+
+would output something like:
+
+-------------
+e15b73ad3db9b48d7d1ade32f8cd23a751fe0ace (dist=3)
+15722f2fa328eaba97022898a305ffc8172db6b1 (dist=2)

+9e622a6dad403b71c40979743bb9d5be17b16bd6 (dist=0)
+-------------
+
+Bisection algorithm discussed
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+First let's define "best bisection point". We will say that a commit X
+is a best bisection point or a best bisection commit if knowing its
+state ("good" or "bad") gives as much information as possible whether
+the state of the commit happens to be "good" or "bad".
+
+This means that the best bisection commits are the commits where the
+following function is maximum:
+
+-------------
+f(X) = min(information_if_good(X), information_if_bad(X))
+-------------
+
+where information_if_good(X) is the information we get if X is good
+and information_if_bad(X) is the information we get if X is bad.
+
+Now we will suppose that there is only one "first bad commit". This
+means that all its descendants are "bad" and all the other commits are
+"good". And we will suppose that all commits have an equal probability
+of being good or bad, or of being the first bad commit, so knowing the
+state of c commits gives always the same amount of information
+wherever these c commits are on the graph and whatever c is. (So we
+suppose that these commits being for example on a branch or near a
+good or a bad commit does not give more or less information).
+
+Let's also suppose that we have a cleaned up graph like one after step
+1) in the bisection algorithm above. This means that we can measure
+the information we get in terms of number of commit we can remove from
+the graph..
+
+And let's take a commit X in the graph.
+
+If X is found to be "good", then we know that its ancestors are all
+"good", so we want to say that:
+
+-------------
+information_if_good(X) = number_of_ancestors(X)  (TRUE)
+-------------
+
+And this is true because at step 1) b) we remove the ancestors of the
+"good" commits.
+
+If X is found to be "bad", then we know that its descendants are all
+"bad", so we want to say that:
+
+-------------
+information_if_bad(X) = number_of_descendants(X)  (WRONG)
+-------------
+
+But this is wrong because at step 1) a) we keep only the ancestors of
+the bad commit. So we get more information when a commit is marked as
+"bad", because we also know that the ancestors of the previous "bad"
+commit that are not ancestors of the new "bad" commit are not the
+first bad commit. We don't know if they are good or bad, but we know
+that they are not the first bad commit because they are not ancestor
+of the new "bad" commit.
+
+So when a commit is marked as "bad" we know we can remove all the
+commits in the graph except those that are ancestors of the new "bad"
+commit. This means that:
+
+-------------
+information_if_bad(X) = N - number_of_ancestors(X)  (TRUE)
+-------------
+
+where N is the number of commits in the (cleaned up) graph.
+
+So in the end this means that to find the best bisection commits we
+should maximize the function:
+
+-------------
+f(X) = min(number_of_ancestors(X), N - number_of_ancestors(X))
+-------------
+
+And this is nice because at step 2) we compute number_of_ancestors(X)
+and so at step 3) we compute f(X).
+
+Let's take the following graph as an example:
+
+-------------
+           G-H-I-J
+          /       \
+A-B-C-D-E-F         O
+          \       /
+           K-L-M-N
+-------------
+
+If we compute the following non optimal function on it:
+
+-------------
+g(X) = min(number_of_ancestors(X), number_of_descendants(X))
+-------------
+
+we get:
+
+-------------
+           4 3 2 1
+           G-H-I-J
+1 2 3 4 5 6/       \0
+A-B-C-D-E-F         O
+          \       /
+           K-L-M-N
+           4 3 2 1
+-------------
+
+but with the algorithm used by git bisect we get:
+
+-------------
+           7 7 6 5
+           G-H-I-J
+1 2 3 4 5 6/       \0
+A-B-C-D-E-F         O
+          \       /
+           K-L-M-N
+           7 7 6 5
+-------------
+
+So we chose G, H, K or L as the best bisection point, which is better
+than F. Because if for example L is bad, then we will know not only
+that L, M and N are bad but also that G, H, I and J are not the first
+bad commit (since we suppose that there is only one first bad commit
+and it must be an ancestor of L).
+
+So the current algorithm seems to be the best possible given what we
+initially supposed.
+
+Skip algorithm
+~~~~~~~~~~~~~~
+
+When some commits have been skipped (using "git bisect skip"), then
+the bisection algorithm is the same for step 1) to 3). But then we use
+roughly the following steps:
+
+6) sort the commit by decreasing associated value
+
+7) if the first commit has not been skipped, we can return it and stop
+here
+
+8) otherwise filter out all the skipped commits in the sorted list
+
+9) use a pseudo random number generator (PRNG) to generate a random
+number between 0 and 1
+
+10) multiply this random number with its square root to bias it toward
+0
+
+11) multiply the result by the number of commits in the filtered list
+to get an index into this list
+
+12) return the commit at the computed index
+
+Skip algorithm discussed
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+After step 7) (in the skip algorithm), we could check if the second
+commit has been skipped and return it if it is not the case. And in
+fact that was the algorithm we used from when "git bisect skip" was
+developed in git version 1.5.4 (released on February 1st 2008) until
+git version 1.6.4 (released July 29th 2009).
+
+But Ingo Molnar and H. Peter Anvin (another well known linux kernel
+developer) both complained that sometimes the best bisection points
+all happened to be in an area where all the commits are
+untestable. And in this case the user was asked to test many
+untestable commits, which could be very inefficient.
+
+Indeed untestable commits are often untestable because a breakage was
+introduced at one time, and that breakage was fixed only after many
+other commits were introduced.
+
+This breakage is of course most of the time unrelated to the breakage
+we are trying to locate in the commit graph. But it prevents us to
+know if the interesting "bad behavior" is present or not.
+
+So it is a fact that commits near an untestable commit have a high
+probability of being untestable themselves. And the best bisection
+commits are often found together too (due to the bisection algorithm).
+
+This is why it is a bad idea to just chose the next best unskipped
+bisection commit when the first one has been skipped.
+
+We found that most commits on the graph may give quite a lot of
+information when they are tested. And the commits that will not on
+average give a lot of information are the one near the good and bad
+commits.
+
+So using a PRNG with a bias to favor commits away from the good and
+bad commits looked like a good choice.
+
+One obvious improvement to this algorithm would be to look for a
+commit that has an associated value near the one of the best bisection
+commit, and that is on another branch, before using the PRNG. Because
+if such a commit exists, then it is not very likely to be untestable
+too, so it will probably give more information than a nearly randomly
+chosen one.
+
+Checking merge bases
+~~~~~~~~~~~~~~~~~~~~
+
+There is another tweak in the bisection algorithm that has not been
+described in the "bisection algorithm" above.
+
+We supposed in the previous examples that the "good" commits were
+ancestors of the "bad" commit. But this is not a requirement of "git
+bisect".
+
+Of course the "bad" commit cannot be an ancestor of a "good" commit,
+because the ancestors of the good commits are supposed to be
+"good". And all the "good" commits must be related to the bad commit.
+They cannot be on a branch that has no link with the branch of the
+"bad" commit. But it is possible for a good commit to be related to a
+bad commit and yet not be neither one of its ancestor nor one of its
+descendants.
+
+For example, there can be a "main" branch, and a "dev" branch that was
+forked of the main branch at a commit named "D" like this:
+
+-------------
+A-B-C-D-E-F-G  <--main
+       \
+       H-I-J  <--dev
+-------------
+
+The commit "D" is called a "merge base" for branch "main" and "dev"
+because it's the best common ancestor for these branches for a merge.
+
+Now let's suppose that commit J is bad and commit G is good and that
+we apply the bisection algorithm like it has been previously
+described.
+
+As described in step 1) b) of the bisection algorithm, we remove all
+the ancestors of the good commits because they are supposed to be good
+too.
+
+So we would be left with only:
+
+-------------
+H-I-J
+-------------
+
+But what happens if the first bad commit is "B" and if it has been
+fixed in the "main" branch by commit "F"?
+
+The result of such a bisection would be that we would find that H is
+the first bad commit, when in fact it's B. So that would be wrong!
+
+And yes it can happen in practice that people working on one branch
+are not aware that people working on another branch fixed a bug! It
+could also happen that F fixed more than one bug or that it is a
+revert of some big development effort that was not ready to be
+released.
+
+In fact development teams often maintain both a development branch and
+a maintenance branch, and it would be quite easy for them if "git
+bisect" just worked when they want to bisect a regression on the
+development branch that is not on the maintenance branch. They should
+be able to start bisecting using:
+
+-------------
+$ git bisect start dev main
+-------------
+
+To enable that additional nice feature, when a bisection is started
+and when some good commits are not ancestors of the bad commit, we
+first compute the merge bases between the bad and the good commits and
+we chose these merge bases as the first commits that will be checked
+out and tested.
+
+If it happens that one merge base is bad, then the bisection process
+is stopped with a message like:
+
+-------------
+The merge base BBBBBB is bad.
+This means the bug has been fixed between BBBBBB and [GGGGGG,...].
+-------------
+
+where BBBBBB is the sha1 hash of the bad merge base and [GGGGGG,...]
+is a comma separated list of the sha1 of the good commits.
+
+If some of the merge bases are skipped, then the bisection process
+continues, but the following message is printed for each skipped merge
+base:
+
+-------------
+Warning: the merge base between BBBBBB and [GGGGGG,...] must be skipped.
+So we cannot be sure the first bad commit is between MMMMMM and BBBBBB.
+We continue anyway.
+-------------
+
+where BBBBBB is the sha1 hash of the bad commit, MMMMMM is the sha1
+hash of the merge base that is skipped and [GGGGGG,...]  is a comma
+separated list of the sha1 of the good commits.
+
+So if there is no bad merge base, the bisection process continues as
+usual after this step.
+
+Best bisecting practices
+------------------------
+
+Using test suites and git bisect together
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you both have a test suite and use git bisect, then it becomes less
+important to check that all tests pass after each commit. Though of
+course it is probably a good idea to have some checks to avoid
+breaking too many things because it could make bisecting other bugs
+more difficult.
+
+You can focus your efforts to check at a few points (for example rc
+and beta releases) that all the T test cases pass for all the N
+configurations. And when some tests don't pass you can use "git
+bisect" (or better "git bisect run"). So you should perform roughly:
+
+-------------
+c * N * T + b * M * log2(M) tests
+-------------
+
+where c is the number of rounds of test (so a small constant) and b is
+the ratio of bug per commit (hopefully a small constant too).
+
+So of course it's much better as it's O(N \* T) vs O(N \* T \* M) if
+you would test everything after each commit.
+
+This means that test suites are good to prevent some bugs from being
+committed and they are also quite good to tell you that you have some
+bugs. But they are not so good to tell you where some bugs have been
+introduced. To tell you that efficiently, git bisect is needed.
+
+The other nice thing with test suites, is that when you have one, you
+already know how to test for bad behavior. So you can use this
+knowledge to create a new test case for "git bisect" when it appears
+that there is a regression. So it will be easier to bisect the bug and
+fix it. And then you can add the test case you just created to your
+test suite.
+
+So if you know how to create test cases and how to bisect, you will be
+subject to a virtuous circle:
+
+more tests => easier to create tests => easier to bisect => more tests
+
+So test suites and "git bisect" are complementary tools that are very
+powerful and efficient when used together.
+
+Bisecting build failures
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can very easily automatically bisect broken builds using something
+like:
+
+-------------
+$ git bisect start BAD GOOD
+$ git bisect run make
+-------------
+
+Passing sh -c "some commands" to "git bisect run"
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For example:
+
+-------------
+$ git bisect run sh -c "make || exit 125; ./my_app | grep 'good output'"
+-------------
+
+On the other hand if you do this often, then it can be worth having
+scripts to avoid too much typing.
+
+Finding performance regressions
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Here is an example script that comes slightly modified from a real
+world script used by Junio Hamano <<4>>.
+
+This script can be passed to "git bisect run" to find the commit that
+introduced a performance regression:
+
+-------------
+#!/bin/sh
+
+# Build errors are not what I am interested in.
+make my_app || exit 255
+
+# We are checking if it stops in a reasonable amount of time, so
+# let it run in the background...
+
+./my_app >log 2>&1 &
+
+# ... and grab its process ID.
+pid=$!
+
+# ... and then wait for sufficiently long.
+sleep $NORMAL_TIME
+
+# ... and then see if the process is still there.
+if kill -0 $pid
+then
+       # It is still running -- that is bad.
+       kill $pid; sleep 1; kill $pid;
+       exit 1
+else
+       # It has already finished (the $pid process was no more),
+       # and we are happy.
+       exit 0
+fi
+-------------
+
+Following general best practices
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It is obviously a good idea not to have commits with changes that
+knowingly break things, even if some other commits later fix the
+breakage.
+
+It is also a good idea when using any VCS to have only one small
+logical change in each commit.
+
+The smaller the changes in your commit, the most effective "git
+bisect" will be. And you will probably need "git bisect" less in the
+first place, as small changes are easier to review even if they are
+only reviewed by the commiter.
+
+Another good idea is to have good commit messages. They can be very
+helpful to understand why some changes were made.
+
+These general best practices are very helpful if you bisect often.
+
+Avoiding bug prone merges
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+First merges by themselves can introduce some regressions even when
+the merge needs no source code conflict resolution. This is because a
+semantic change can happen in one branch while the other branch is not
+aware of it.
+
+For example one branch can change the semantic of a function while the
+other branch add more calls to the same function.
+
+This is made much worse if many files have to be fixed to resolve
+conflicts. That's why such merges are called "evil merges". They can
+make regressions very difficult to track down. It can even be
+misleading to know the first bad commit if it happens to be such a
+merge, because people might think that the bug comes from bad conflict
+resolution when it comes from a semantic change in one branch.
+
+Anyway "git rebase" can be used to linearize history. This can be used
+either to avoid merging in the first place. Or it can be used to
+bisect on a linear history instead of the non linear one, as this
+should give more information in case of a semantic change in one
+branch.
+
+Merges can be also made simpler by using smaller branches or by using
+many topic branches instead of only long version related branches.
+
+And testing can be done more often in special integration branches
+like linux-next for the linux kernel.
+
+Adapting your work-flow
+~~~~~~~~~~~~~~~~~~~~~~~
+
+A special work-flow to process regressions can give great results.
+
+Here is an example of a work-flow used by Andreas Ericsson:
+
+* write, in the test suite, a test script that exposes the regression
+* use "git bisect run" to find the commit that introduced it
+* fix the bug that is often made obvious by the previous step
+* commit both the fix and the test script (and if needed more tests)
+
+And here is what Andreas said about this work-flow <<5>>:
+
+_____________
+To give some hard figures, we used to have an average report-to-fix
+cycle of 142.6 hours (according to our somewhat weird bug-tracker
+which just measures wall-clock time). Since we moved to git, we've
+lowered that to 16.2 hours. Primarily because we can stay on top of
+the bug fixing now, and because everyone's jockeying to get to fix
+bugs (we're quite proud of how lazy we are to let git find the bugs
+for us). Each new release results in ~40% fewer bugs (almost certainly
+due to how we now feel about writing tests).
+_____________
+
+Clearly this work-flow uses the virtuous circle between test suites
+and "git bisect". In fact it makes it the standard procedure to deal
+with regression.
+
+In other messages Andreas says that they also use the "best practices"
+described above: small logical commits, topic branches, no evil
+merge,... These practices all improve the bisectability of the commit
+graph, by making it easier and more useful to bisect.
+
+So a good work-flow should be designed around the above points. That
+is making bisecting easier, more useful and standard.
+
+Involving QA people and if possible end users
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+One nice about "git bisect" is that it is not only a developer
+tool. It can effectively be used by QA people or even end users (if
+they have access to the source code or if they can get access to all
+the builds).
+
+There was a discussion at one point on the linux kernel mailing list
+of whether it was ok to always ask end user to bisect, and very good
+points were made to support the point of view that it is ok.
+
+For example David Miller wrote <<6>>:
+
+_____________
+What people don't get is that this is a situation where the "end node
+principle" applies. When you have limited resources (here: developers)
+you don't push the bulk of the burden upon them. Instead you push
+things out to the resource you have a lot of, the end nodes (here:
+users), so that the situation actually scales.
+_____________
+
+This means that it is often "cheaper" if QA people or end users can do
+it.
+
+What is interesting too is that end users that are reporting bugs (or
+QA people that reproduced a bug) have access to the environment where
+the bug happens. So they can often more easily reproduce a
+regression. And if they can bisect, then more information will be
+extracted from the environment where the bug happens, which means that
+it will be easier to understand and then fix the bug.
+
+For open source projects it can be a good way to get more useful
+contributions from end users, and to introduce them to QA and
+development activities.
+
+Using complex scripts
+~~~~~~~~~~~~~~~~~~~~~
+
+In some cases like for kernel development it can be worth developing
+complex scripts to be able to fully automate bisecting.
+
+Here is what Ingo Molnar says about that <<7>>:
+
+_____________
+i have a fully automated bootup-hang bisection script. It is based on
+"git-bisect run". I run the script, it builds and boots kernels fully
+automatically, and when the bootup fails (the script notices that via
+the serial log, which it continuously watches - or via a timeout, if
+the system does not come up within 10 minutes it's a "bad" kernel),
+the script raises my attention via a beep and i power cycle the test
+box. (yeah, i should make use of a managed power outlet to 100%
+automate it)
+_____________
+
+Combining test suites, git bisect and other systems together
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+We have seen that test suites an git bisect are very powerful when
+used together. It can be even more powerful if you can combine them
+with other systems.
+
+For example some test suites could be run automatically at night with
+some unusual (or even random) configurations. And if a regression is
+found by a test suite, then "git bisect" can be automatically
+launched, and its result can be emailed to the author of the first bad
+commit found by "git bisect", and perhaps other people too. And a new
+entry in the bug tracking system could be automatically created too.
+
+
+The future of bisecting
+-----------------------
+
+"git replace"
+~~~~~~~~~~~~~
+
+We saw earlier that "git bisect skip" is now using a PRNG to try to
+avoid areas in the commit graph where commits are untestable. The
+problem is that sometimes the first bad commit will be in an
+untestable area.
+
+To simplify the discussion we will suppose that the untestable area is
+a simple string of commits and that it was created by a breakage
+introduced by one commit (let's call it BBC for bisect breaking
+commit) and later fixed by another one (let's call it BFC for bisect
+fixing commit).
+
+For example:
+
+-------------
+...-Y-BBC-X1-X2-X3-X4-X5-X6-BFC-Z-...
+-------------
+
+where we know that Y is good and BFC is bad, and where BBC and X1 to
+X6 are untestable.
+
+In this case if you are bisecting manually, what you can do is create
+a special branch that starts just before the BBC. The first commit in
+this branch should be the BBC with the BFC squashed into it. And the
+other commits in the branch should be the commits between BBC and BFC
+rebased on the first commit of the branch and then the commit after
+BFC also rebased on.
+
+For example:
+
+-------------
+      (BBC+BFC)-X1'-X2'-X3'-X4'-X5'-X6'-Z'
+     /
+...-Y-BBC-X1-X2-X3-X4-X5-X6-BFC-Z-...
+-------------
+
+where commits quoted with ' have been rebased.
+
+You can easily create such a branch with Git using interactive rebase.
+
+For example using:
+
+-------------
+$ git rebase -i Y Z
+-------------
+
+and then moving BFC after BBC and squashing it.
+
+After that you can start bisecting as usual in the new branch and you
+should eventually find the first bad commit.
+
+For example:
+
+-------------
+$ git bisect start Z' Y
+-------------
+
+If you are using "git bisect run", you can use the same manual fix up
+as above, and then start another "git bisect run" in the special
+branch. Or as the "git bisect" man page says, the script passed to
+"git bisect run" can apply a patch before it compiles and test the
+software <<8>>. The patch should turn a current untestable commits
+into a testable one. So the testing will result in "good" or "bad" and
+"git bisect" will be able to find the first bad commit. And the script
+should not forget to remove the patch once the testing is done before
+exiting from the script.
+
+(Note that instead of a patch you can use "git cherry-pick BFC" to
+apply the fix, and in this case you should use "git reset --hard
+HEAD^" to revert the cherry-pick after testing and before returning
+from the script.)
+
+But the above ways to work around untestable areas are a little bit
+clunky. Using special branches is nice because these branches can be
+shared by developers like usual branches, but the risk is that people
+will get many such branches. And it disrupts the normal "git bisect"
+work-flow. So, if you want to use "git bisect run" completely
+automatically, you have to add special code in your script to restart
+bisection in the special branches.
+
+Anyway one can notice in the above special branch example that the Z'
+and Z commits should point to the same source code state (the same
+"tree" in git parlance). That's because Z' result from applying the
+same changes as Z just in a slightly different order.
+
+So if we could just "replace" Z by Z' when we bisect, then we would
+not need to add anything to a script. It would just work for anyone in
+the project sharing the special branches and the replacements.
+
+With the example above that would give:
+
+-------------
+      (BBC+BFC)-X1'-X2'-X3'-X4'-X5'-X6'-Z'-...
+     /
+...-Y-BBC-X1-X2-X3-X4-X5-X6-BFC-Z
+-------------
+
+That's why the "git replace" command was created. Technically it
+stores replacements "refs" in the "refs/replace/" hierarchy. These
+"refs" are like branches (that are stored in "refs/heads/") or tags
+(that are stored in "refs/tags"), and that means that they can
+automatically be shared like branches or tags among developers.
+
+"git replace" is a very powerful mechanism. It can be used to fix
+commits in already released history, for example to change the commit
+message or the author. And it can also be used instead of git "grafts"
+to link a repository with another old repository.
+
+In fact it's this last feature that "sold" it to the git community, so
+it is now in the "master" branch of git's git repository and it should
+be released in git 1.6.5 in October or November 2009.
+
+One problem with "git replace" is that currently it stores all the
+replacements refs in "refs/replace/", but it would be perhaps better
+if the replacement refs that are useful only for bisecting would be in
+"refs/replace/bisect/". This way the replacement refs could be used
+only for bisecting, while other refs directly in "refs/replace/" would
+be used nearly all the time.
+
+Bisecting sporadic bugs
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Another possible improvement to "git bisect" would be to optionally
+add some redundancy to the tests performed so that it would be more
+reliable when tracking sporadic bugs.
+
+This has been requested by some kernel developers because some bugs
+called sporadic bugs do not appear in all the kernel builds because
+they are very dependent on the compiler output.
+
+The idea is that every 3 test for example, "git bisect" could ask the
+user to test a commit that has already been found to be "good" or
+"bad" (because one of its descendants or one of its ancestors has been
+found to be "good" or "bad" respectively). If it happens that a commit
+has been previously incorrectly classified then the bisection can be
+aborted early, hopefully before too many mistakes have been made. Then
+the user will have to look at what happened and then restart the
+bisection using a fixed bisect log.
+
+There is already a project called BBChop created by Ealdwulf Wuffinga
+on Github that does something like that using Bayesian Search Theory
+<<9>>:
+
+_____________
+BBChop is like 'git bisect' (or equivalent), but works when your bug
+is intermittent. That is, it works in the presence of false negatives
+(when a version happens to work this time even though it contains the
+bug). It assumes that there are no false positives (in principle, the
+same approach would work, but adding it may be non-trivial).
+_____________
+
+But BBChop is independent of any VCS and it would be easier for Git
+users to have something integrated in Git.
+
+Conclusion
+----------
+
+We have seen that regressions are an important problem, and that "git
+bisect" has nice features that complement very well practices and
+other tools, especially test suites, that are generally used to fight
+regressions. But it might be needed to change some work-flows and
+(bad) habits to get the most out of it.
+
+Some improvements to the algorithms inside "git bisect" are possible
+and some new features could help in some cases, but overall "git
+bisect" works already very well, is used a lot, and is already very
+useful. To back up that last claim, let's give the final word to Ingo
+Molnar when he was asked by the author how much time does he think
+"git bisect" saves him when he uses it:
+
+_____________
+a _lot_.
+
+About ten years ago did i do my first 'bisection' of a Linux patch
+queue. That was prior the Git (and even prior the BitKeeper) days. I
+literally days spent sorting out patches, creating what in essence
+were standalone commits that i guessed to be related to that bug.
+
+It was a tool of absolute last resort. I'd rather spend days looking
+at printk output than do a manual 'patch bisection'.
+
+With Git bisect it's a breeze: in the best case i can get a ~15 step
+kernel bisection done in 20-30 minutes, in an automated way. Even with
+manual help or when bisecting multiple, overlapping bugs, it's rarely
+more than an hour.
+
+In fact it's invaluable because there are bugs i would never even
+_try_ to debug if it wasn't for git bisect. In the past there were bug
+patterns that were immediately hopeless for me to debug - at best i
+could send the crash/bug signature to lkml and hope that someone else
+can think of something.
+
+And even if a bisection fails today it tells us something valuable
+about the bug: that it's non-deterministic - timing or kernel image
+layout dependent.
+
+So git bisect is unconditional goodness - and feel free to quote that
+;-)

 A reference is used in git to specify branches and tags.  A
-branch head is stored under `$GIT_DIR/refs/heads` directory, and
-a tag is stored under `$GIT_DIR/refs/tags` directory.  git
-imposes the following rules on how refs are named:

+a tag is stored under the `$GIT_DIR/refs/tags` directory (or, if refs

+. A colon `:` is used as in `srcref:dstref` to mean "use srcref\'s

+  'git cat-file': "git cat-file blob v1.3.3:refs.c".
+
+. at-open-brace `@{` is used as a notation to access a reflog entry.
+
+With the `--print` option, if 'refname' is acceptable, it prints the
+canonicalized name of a hypothetical reference with that name.  That is,
+it prints 'refname' with any extra `/` characters removed.
+
+With the `--branch` option, it expands the ``previous branch syntax''
+`@{-n}`.  For example, `@{-1}` is a way to refer the last branch you
+were on.  This option should be used by porcelains to accept this
+syntax anywhere a branch name is expected, so they can act as if you

+
+SYNOPSIS
+--------
+'git difftool' [<options>] <commit>{0,2} [--] [<path>...]
+
+DESCRIPTION
+-----------
+'git difftool' is a git command that allows you to compare and edit files
+between revisions using common diff tools.  'git difftool' is a frontend
+to 'git diff' and accepts the same options and arguments.
+
+OPTIONS
+-------
+-y::
+--no-prompt::
+       Do not prompt before launching a diff tool.
+
+--prompt::
+       Prompt before each invocation of the diff tool.
+       This is the default behaviour; the option is provided to
+       override any configuration settings.
+
+-t <tool>::
+--tool=<tool>::
+       Use the diff tool specified by <tool>.
+       Valid merge tools are:
+       kdiff3, kompare, tkdiff, meld, xxdiff, emerge, vimdiff, gvimdiff,
+       ecmerge, diffuse, opendiff, p4merge and araxis.
++
+If a diff tool is not specified, 'git difftool'
+will use the configuration variable `diff.tool`.  If the
+configuration variable `diff.tool` is not set, 'git difftool'
+will pick a suitable default.
++
+You can explicitly provide a full path to the tool by setting the
+configuration variable `difftool.<tool>.path`. For example, you
+can configure the absolute path to kdiff3 by setting
+`difftool.kdiff3.path`. Otherwise, 'git difftool' assumes the
+tool is available in PATH.
++
+Instead of running one of the known diff tools,
+'git difftool' can be customized to run an alternative program
+by specifying the command line to invoke in a configuration
+variable `difftool.<tool>.cmd`.
++
+When 'git difftool' is invoked with this tool (either through the
+`-t` or `--tool` option or the `diff.tool` configuration variable)
+the configured command line will be invoked with the following
+variables available: `$LOCAL` is set to the name of the temporary
+file containing the contents of the diff pre-image and `$REMOTE`
+is set to the name of the temporary file containing the contents
+of the diff post-image.  `$BASE` is provided for compatibility
+with custom merge tool commands and has the same value as `$LOCAL`.
+
+-x <command>::
+--extcmd=<command>::
+       Specify a custom command for viewing diffs.
+       'git-difftool' ignores the configured defaults and runs
+       `$command $LOCAL $REMOTE` when this option is specified.
+
+-g::
+--gui::
+       When 'git-difftool' is invoked with the `-g` or `--gui` option
+       the default diff tool will be read from the configured
+       `diff.guitool` variable instead of `diff.tool`.
+
+See linkgit:git-diff[1] for the full list of supported options.
+
+CONFIG VARIABLES
+----------------
+'git difftool' falls back to 'git mergetool' config variables when the
+difftool equivalents have not been defined.
+
+diff.tool::
+       The default diff tool to use.
+
+diff.guitool::
+       The default diff tool to use when `--gui` is specified.
+
+difftool.<tool>.path::
+       Override the path for the given tool.  This is useful in case
+       your tool is not in the PATH.
+
+difftool.<tool>.cmd::
+       Specify the command to invoke the specified diff tool.
++
+See the `--tool=<tool>` option above for more details.
+
+difftool.prompt::
+       Prompt before each invocation of the diff tool.
+

+===================
+
+NAME
+----
+git-http-backend - Server side implementation of Git over HTTP
+
+SYNOPSIS
+--------
+[verse]
+'git http-backend'
+
+DESCRIPTION
+-----------
+A simple CGI program to serve the contents of a Git repository to Git
+clients accessing the repository over http:// and https:// protocols.
+The program supports clients fetching using both the smart HTTP protocol
+and the backwards-compatible dumb HTTP protocol, as well as clients
+pushing using the smart HTTP protocol.
+
+It verifies that the directory has the magic file
+"git-daemon-export-ok", and it will refuse to export any git directory
+that hasn't explicitly been marked for export this way (unless the
+GIT_HTTP_EXPORT_ALL environmental variable is set).
+
+By default, only the `upload-pack` service is enabled, which serves
+'git fetch-pack' and 'git ls-remote' clients, which are invoked from
+'git fetch', 'git pull', and 'git clone'.  If the client is authenticated,
+the `receive-pack` service is enabled, which serves 'git send-pack'
+clients, which is invoked from 'git push'.
+
+SERVICES
+--------
+These services can be enabled/disabled using the per-repository
+configuration file:
+
+http.getanyfile::
+       This serves older Git clients which are unable to use the
+       upload pack service.  When enabled, clients are able to read
+       any file within the repository, including objects that are
+       no longer reachable from a branch but are still present.
+       It is enabled by default, but a repository can disable it
+       by setting this configuration item to `false`.
+
+http.uploadpack::
+       This serves 'git fetch-pack' and 'git ls-remote' clients.
+       It is enabled by default, but a repository can disable it
+       by setting this configuration item to `false`.
+
+http.receivepack::
+       This serves 'git send-pack' clients, allowing push.  It is
+       disabled by default for anonymous users, and enabled by
+       default for users authenticated by the web server.  It can be
+       disabled by setting this item to `false`, or enabled for all
+       users, including anonymous users, by setting it to `true`.
+
+URL TRANSLATION
+---------------
+To determine the location of the repository on disk, 'git http-backend'
+concatenates the environment variables PATH_INFO, which is set
+automatically by the web server, and GIT_PROJECT_ROOT, which must be set
+manually in the web server configuration.  If GIT_PROJECT_ROOT is not
+set, 'git http-backend' reads PATH_TRANSLATED, which is also set
+automatically by the web server.
+
+EXAMPLES
+--------
+All of the following examples map 'http://$hostname/git/foo/bar.git'
+to '/var/www/git/foo/bar.git'.
+
+Apache 2.x::
+       Ensure mod_cgi, mod_alias, and mod_env are enabled, set
+       GIT_PROJECT_ROOT (or DocumentRoot) appropriately, and
+       create a ScriptAlias to the CGI:
++
+----------------------------------------------------------------
+SetEnv GIT_PROJECT_ROOT /var/www/git
+SetEnv GIT_HTTP_EXPORT_ALL
+ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/
+----------------------------------------------------------------
++
+To enable anonymous read access but authenticated write access,
+require authorization with a LocationMatch directive:
++
+----------------------------------------------------------------
+<LocationMatch "^/git/.*/git-receive-pack$">
+       AuthType Basic
+       AuthName "Git Access"
+       Require group committers
+       ...
+</LocationMatch>
+----------------------------------------------------------------
++
+To require authentication for both reads and writes, use a Location
+directive around the repository, or one of its parent directories:
++
+----------------------------------------------------------------
+<Location /git/private>
+       AuthType Basic
+       AuthName "Private Git Access"
+       Require group committers
+       ...
+</Location>
+----------------------------------------------------------------
++
+To serve gitweb at the same url, use a ScriptAliasMatch to only
+those URLs that 'git http-backend' can handle, and forward the
+rest to gitweb:
++
+----------------------------------------------------------------
+ScriptAliasMatch \
+       "(?x)^/git/(.*/(HEAD | \
+                       info/refs | \
+                       objects/(info/[^/]+ | \
+                                [0-9a-f]{2}/[0-9a-f]{38} | \
+                                pack/pack-[0-9a-f]{40}\.(pack|idx)) | \
+                       git-(upload|receive)-pack))$" \
+       /usr/libexec/git-core/git-http-backend/$1
+
+ScriptAlias /git/ /var/www/cgi-bin/gitweb.cgi/
+----------------------------------------------------------------
+
+Accelerated static Apache 2.x::
+       Similar to the above, but Apache can be used to return static
+       files that are stored on disk.  On many systems this may
+       be more efficient as Apache can ask the kernel to copy the
+       file contents from the file system directly to the network:
++
+----------------------------------------------------------------
+SetEnv GIT_PROJECT_ROOT /var/www/git
+
+AliasMatch ^/git/(.*/objects/[0-9a-f]{2}/[0-9a-f]{38})$          /var/www/git/$1
+AliasMatch ^/git/(.*/objects/pack/pack-[0-9a-f]{40}.(pack|idx))$ /var/www/git/$1
+ScriptAlias /git/ /usr/libexec/git-core/git-http-backend/
+----------------------------------------------------------------
++
+This can be combined with the gitweb configuration:
++
+----------------------------------------------------------------
+SetEnv GIT_PROJECT_ROOT /var/www/git
+
+AliasMatch ^/git/(.*/objects/[0-9a-f]{2}/[0-9a-f]{38})$          /var/www/git/$1
+AliasMatch ^/git/(.*/objects/pack/pack-[0-9a-f]{40}.(pack|idx))$ /var/www/git/$1
+ScriptAliasMatch \
+       "(?x)^/git/(.*/(HEAD | \
+                       info/refs | \
+                       objects/info/[^/]+ | \
+                       git-(upload|receive)-pack))$" \
+       /usr/libexec/git-core/git-http-backend/$1
+ScriptAlias /git/ /var/www/cgi-bin/gitweb.cgi/
+----------------------------------------------------------------
+
+
+ENVIRONMENT
+-----------
+'git http-backend' relies upon the CGI environment variables set
+by the invoking web server, including:
+
+* PATH_INFO (if GIT_PROJECT_ROOT is set, otherwise PATH_TRANSLATED)
+* REMOTE_USER
+* REMOTE_ADDR
+* CONTENT_TYPE
+* QUERY_STRING
+* REQUEST_METHOD
+
+The GIT_HTTP_EXPORT_ALL environmental variable may be passed to
+'git-http-backend' to bypass the check for the "git-daemon-export-ok"
+file in each repository before allowing export of that repository.
+
+The backend process sets GIT_COMMITTER_NAME to '$REMOTE_USER' and
+GIT_COMMITTER_EMAIL to '$\{REMOTE_USER}@http.$\{REMOTE_ADDR\}',
+ensuring that any reflogs created by 'git-receive-pack' contain some
+identifying information of the remote user who performed the push.
+
+All CGI environment variables are available to each of the hooks
+invoked by the 'git-receive-pack'.

-HOW MERGE WORKS
----------------
-
-A merge is always between the current `HEAD` and one or more
-commits (usually, branch head or tag), and the index file must
-match the tree of `HEAD` commit (i.e. the contents of the last commit)
-when it starts out.  In other words, `git diff --cached HEAD` must
-report no changes.  (One exception is when the changed index
-entries are already in the same state that would result from
-the merge anyway.)
-
-Three kinds of merge can happen:
-
-* The merged commit is already contained in `HEAD`. This is the
-  simplest case, called "Already up-to-date."
-
-* `HEAD` is already contained in the merged commit. This is the
-  most common case especially when invoked from 'git pull':
-  you are tracking an upstream repository, have committed no local
-  changes and now you want to update to a newer upstream revision.
-  Your `HEAD` (and the index) is updated to point at the merged
-  commit, without creating an extra merge commit.  This is
-  called "Fast-forward".
-
-* Both the merged commit and `HEAD` are independent and must be
-  tied together by a merge commit that has both of them as its parents.
-  The rest of this section describes this "True merge" case.
-
-The chosen merge strategy merges the two commits into a single
-new source tree.
-When things merge cleanly, this is what happens:
-
-1. The results are updated both in the index file and in your
-   working tree;
-2. Index file is written out as a tree;
-3. The tree gets committed; and
-4. The `HEAD` pointer gets advanced.
-
-Because of 2., we require that the original state of the index
-file matches exactly the current `HEAD` commit; otherwise we
-will write out your local changes already registered in your
-index file along with the merge result, which is not good.
-Because 1. involves only those paths differing between your
-branch and the remote branch you are pulling from during the
-merge (which is typically a fraction of the whole tree), you can
-have local modifications in your working tree as long as they do
-not overlap with what the merge updates.
-
-When there are conflicts, the following happens:
-
-1. `HEAD` stays the same.
-
-2. Cleanly merged paths are updated both in the index file and

+
+
+PRE-MERGE CHECKS
+----------------
+
+Before applying outside changes, you should get your own work in
+good shape and committed locally, so it will not be clobbered if
+there are conflicts.  See also linkgit:git-stash[1].
+'git pull' and 'git merge' will stop without doing anything when
+local uncommitted changes overlap with files that 'git pull'/'git
+merge' may need to update.
+
+To avoid recording unrelated changes in the merge commit,
+'git pull' and 'git merge' will also abort if there are any changes
+registered in the index relative to the `HEAD` commit.  (One
+exception is when the changed index entries are in the state that
+would result from the merge already.)
+
+If all named commits are already ancestors of `HEAD`, 'git merge'
+will exit early with the message "Already up-to-date."
+
+FAST-FORWARD MERGE
+------------------
+
+Often the current branch head is an ancestor of the named commit.
+This is the most common case especially when invoked from 'git
+pull': you are tracking an upstream repository, you have committed
+no local changes, and now you want to update to a newer upstream
+revision.  In this case, a new commit is not needed to store the
+combined history; instead, the `HEAD` (along with the index) is
+updated to point at the named commit, without creating an extra
+merge commit.
+
+This behavior can be suppressed with the `--no-ff` option.

+
+Except in a fast-forward merge (see above), the branches to be
+merged must be tied together by a merge commit that has both of them
+as its parents.
+
+A merged version reconciling the changes from all branches to be
+merged is committed, and your `HEAD`, index, and working tree are
+updated to it.  It is possible to have modifications in the working
+tree as long as they do not overlap; the update will preserve them.
+
+When it is not obvious how to reconcile the changes, the following
+happens:
+
+1. The `HEAD` pointer stays the same.
+2. The `MERGE_HEAD` ref is set to point to the other branch head.
+3. Paths that merged cleanly are updated both in the index file and
    in your working tree.

+   versions: stage 1 stores the version from the common ancestor,
+   stage 2 from `HEAD`, and stage 3 from `MERGE_HEAD` (you
    can inspect the stages with `git ls-files -u`).  The working
    tree files contain the result of the "merge" program; i.e. 3-way
-   merge results with familiar conflict markers `<<< === >>>`.

+5. No other changes are made.  In particular, the local
    modifications you had before you started merge will stay the
    same and the index entries for them stay as they were,
    i.e. matching `HEAD`.
 
+If you tried a merge which resulted in complex conflicts and
+want to start over, you can recover with `git reset --merge`.

+Note about fast-forwards
+------------------------
+
+When an update changes a branch (or more in general, a ref) that used to
+point at commit A to point at another commit B, it is called a
+fast-forward update if and only if B is a descendant of A.
+
+In a fast-forward update from A to B, the set of commits that the original
+commit A built on top of is a subset of the commits the new commit B
+builds on top of.  Hence, it does not lose any history.
+
+In contrast, a non-fast-forward update will lose history.  For example,
+suppose you and somebody else started at the same commit X, and you built
+a history leading to commit B while the other person built a history
+leading to commit A.  The history looks like this:
+
+----------------
+
+      B
+     /
+ ---X---A
+
+----------------
+
+Further suppose that the other person already pushed changes leading to A
+back to the original repository you two obtained the original commit X.
+
+The push done by the other person updated the branch that used to point at
+commit X to point at commit A.  It is a fast-forward.
+
+But if you try to push, you will attempt to update the branch (that
+now points at A) with commit B.  This does _not_ fast-forward.  If you did
+so, the changes introduced by commit A will be lost, because everybody
+will now start building on top of B.
+
+The command by default does not allow an update that is not a fast-forward
+to prevent such loss of history.
+
+If you do not want to lose your work (history from X to B) nor the work by
+the other person (history from X to A), you would need to first fetch the
+history from the repository, create a history that contains changes done
+by both parties, and push the result back.
+
+You can perform "git pull", resolve potential conflicts, and "git push"
+the result.  A "git pull" will create a merge commit C between commits A
+and B.
+
+----------------
+
+      B---C
+     /   /
+ ---X---A
+
+----------------
+
+Updating A with the resulting merge commit will fast-forward and your
+push will be accepted.
+
+Alternatively, you can rebase your change between X and B on top of A,
+with "git pull --rebase", and push the result back.  The rebase will
+create a new commit D that builds the change between X and B on top of
+A.
+
+----------------
+
+      B   D
+     /   /
+ ---X---A
+
+----------------
+
+Again, updating A with this commit will fast-forward and your push will be
+accepted.
+
+There is another common situation where you may encounter non-fast-forward
+rejection when you try to push, and it is possible even when you are
+pushing into a repository nobody else pushes into. After you push commit
+A yourself (in the first picture in this section), replace it with "git
+commit --amend" to produce commit B, and you try to push it out, because
+forgot that you have pushed A out already. In such a case, and only if
+you are certain that nobody in the meantime fetched your earlier commit A
+(and started building on top of it), you can run "git push --force" to
+overwrite it. In other words, "git push --force" is a method reserved for
+a case where you do mean to lose history.
+
+
 Examples
 --------
 
+git push::
+       Works like `git push <remote>`, where <remote> is the
+       current branch's remote (or `origin`, if no remote is
+       configured for the current branch).
+
+git push origin::
+       Without additional configuration, works like
+       `git push origin :`.
++
+The default behavior of this command when no <refspec> is given can be
+configured by setting the `push` option of the remote.
++
+For example, to default to pushing only the current branch to `origin`
+use `git config remote.origin.push HEAD`.  Any valid <refspec> (like
+the ones in the examples below) can be configured as the default for
+`git push origin`.

+
+"git read-tree" and other merge-based commands ("git merge", "git
+checkout"...) can help maintaining skip-worktree bitmap and working
+directory update. `$GIT_DIR/info/sparse-checkout` is used to
+define the skip-worktree reference bitmap. When "git read-tree" needs
+to update working directory, it will reset skip-worktree bit in index
+based on this file, which uses the same syntax as .gitignore files.
+If an entry matches a pattern in this file, skip-worktree will be
+set on that entry. Otherwise, skip-worktree will be unset.
+
+Then it compares the new skip-worktree value with the previous one. If
+skip-worktree turns from unset to set, it will add the corresponding
+file back. If it turns from set to unset, that file will be removed.
+
+While `$GIT_DIR/info/sparse-checkout` is usually used to specify what
+files are in. You can also specify what files are _not_ in, using
+negate patterns. For example, to remove file "unwanted":
+
+----------------
+*
+!unwanted
+----------------
+
+Another tricky thing is fully repopulating working directory when you
+no longer want sparse checkout. You cannot just disable "sparse
+checkout" because skip-worktree are still in the index and you working
+directory is still sparsely populated. You should re-populate working
+directory with the `$GIT_DIR/info/sparse-checkout` file content as
+follows:
+
+----------------
+*
+----------------
+
+Then you can disable sparse checkout. Sparse checkout support in "git
+read-tree" and similar commands is disabled by default. You need to
+turn `core.sparseCheckout` on in order to have sparse checkout
+support.

+NAME
+----
+git-remote-helpers - Helper programs for interoperation with remote git
+
+SYNOPSIS
+--------
+'git remote-<transport>' <remote>
+
+DESCRIPTION
+-----------
+
+These programs are normally not used directly by end users, but are
+invoked by various git programs that interact with remote repositories
+when the repository they would operate on will be accessed using
+transport code not linked into the main git binary. Various particular
+helper programs will behave as documented here.
+
+COMMANDS
+--------
+
+Commands are given by the caller on the helper's standard input, one per line.
+
+'capabilities'::
+       Lists the capabilities of the helper, one per line, ending
+       with a blank line. Each capability may be preceded with '*'.
+       This marks them mandatory for git version using the remote
+       helper to understand (unknown mandatory capability is fatal
+       error).
+
+'list'::
+       Lists the refs, one per line, in the format "<value> <name>
+       [<attr> ...]". The value may be a hex sha1 hash, "@<dest>" for
+       a symref, or "?" to indicate that the helper could not get the
+       value of the ref. A space-separated list of attributes follows
+       the name; unrecognized attributes are ignored. After the
+       complete list, outputs a blank line.
++
+If 'push' is supported this may be called as 'list for-push'
+to obtain the current refs prior to sending one or more 'push'
+commands to the helper.
+
+'option' <name> <value>::
+       Set the transport helper option <name> to <value>.  Outputs a
+       single line containing one of 'ok' (option successfully set),

+       (option <name> is supported but <value> is not correct
+       for it).  Options should be set before other commands,
+       and may how those commands behave.
++
+Supported if the helper has the "option" capability.
+
+'fetch' <sha1> <name>::
+       Fetches the given object, writing the necessary objects
+       to the database.  Fetch commands are sent in a batch, one
+       per line, and the batch is terminated with a blank line.
+       Outputs a single blank line when all fetch commands in the
+       same batch are complete. Only objects which were reported
+       in the ref list with a sha1 may be fetched this way.
++
+Optionally may output a 'lock <file>' line indicating a file under
+GIT_DIR/objects/pack which is keeping a pack until refs can be
+suitably updated.
++
+Supported if the helper has the "fetch" capability.
+
+'push' +<src>:<dst>::
+       Pushes the given <src> commit or branch locally to the
+       remote branch described by <dst>.  A batch sequence of
+       one or more push commands is terminated with a blank line.
++
+Zero or more protocol options may be entered after the last 'push'
+command, before the batch's terminating blank line.
++
+When the push is complete, outputs one or more 'ok <dst>' or
+'error <dst> <why>?' lines to indicate success or failure of
+each pushed ref.  The status report output is terminated by
+a blank line.  The option field <why> may be quoted in a C
+style string if it contains an LF.
++
+Supported if the helper has the "push" capability.
+
+'import' <name>::
+       Produces a fast-import stream which imports the current value
+       of the named ref. It may additionally import other refs as
+       needed to construct the history efficiently. The script writes
+       to a helper-specific private namespace. The value of the named
+       ref should be written to a location in this namespace derived
+       by applying the refspecs from the "refspec" capability to the
+       name of the ref.
++
+Supported if the helper has the "import" capability.
+
+'connect' <service>::
+       Connects to given service. Standard input and standard output
+       of helper are connected to specified service (git prefix is
+       included in service name so e.g. fetching uses 'git-upload-pack'
+       as service) on remote side. Valid replies to this command are
+       empty line (connection established), 'fallback' (no smart
+       transport support, fall back to dumb transports) and just
+       exiting with error message printed (can't connect, don't
+       bother trying to fall back). After line feed terminating the
+       positive (empty) response, the output of service starts. After
+       the connection ends, the remote helper exits.
++
+Supported if the helper has the "connect" capability.
+
+If a fatal error occurs, the program writes the error message to
+stderr and exits. The caller should expect that a suitable error
+message has been printed if the child closes the connection without
+completing a valid response for the current command.
+
+Additional commands may be supported, as may be determined from
+capabilities reported by the helper.
+
+CAPABILITIES
+------------
+
+'fetch'::
+       This helper supports the 'fetch' command.
+
+'option'::
+       This helper supports the option command.
+
+'push'::
+       This helper supports the 'push' command.
+
+'import'::
+       This helper supports the 'import' command.
+
+'refspec' 'spec'::
+       When using the import command, expect the source ref to have
+       been written to the destination ref. The earliest applicable
+       refspec takes precedence. For example
+       "refs/heads/*:refs/svn/origin/branches/*" means that, after an
+       "import refs/heads/name", the script has written to
+       refs/svn/origin/branches/name. If this capability is used at
+       all, it must cover all refs reported by the list command; if
+       it is not used, it is effectively "*:*"
+
+'connect'::
+       This helper supports the 'connect' command.
+
+REF LIST ATTRIBUTES
+-------------------
+
+'for-push'::
+       The caller wants to use the ref list to prepare push
+       commands.  A helper might chose to acquire the ref list by
+       opening a different type of connection to the destination.
+
+'unchanged'::
+       This ref is unchanged since the last import or fetch, although
+       the helper cannot necessarily determine what value that produced.
+
+OPTIONS
+-------
+'option verbosity' <N>::
+       Change the level of messages displayed by the helper.
+       When N is 0 the end-user has asked the process to be
+       quiet, and the helper should produce only error output.
+       N of 1 is the default level of verbosity, higher values
+       of N correspond to the number of -v flags passed on the
+       command line.
+
+'option progress' \{'true'|'false'\}::
+       Enable (or disable) progress messages displayed by the
+       transport helper during a command.
+
+'option depth' <depth>::
+       Deepen the history of a shallow repository.
+
+'option followtags' \{'true'|'false'\}::
+       If enabled the helper should automatically fetch annotated
+       tag objects if the object the tag points at was transferred
+       during the fetch command.  If the tag is not fetched by
+       the helper a second fetch command will usually be sent to
+       ask for the tag specifically.  Some helpers may be able to
+       use this option to avoid a second network connection.
+
+'option dry-run' \{'true'|'false'\}:
+       If true, pretend the operation completed successfully,
+       but don't actually change any repository data.  For most
+       helpers this only applies to the 'push', if supported.
+
+'option servpath <c-style-quoted-path>'::
+       Set service path (--upload-pack, --receive-pack etc.) for
+       next connect. Remote helper MAY support this option. Remote
+       helper MUST NOT rely on this option being set before
+       connect request occurs.

+NAME
+----
+git-replace - Create, list, delete refs to replace objects
+
+SYNOPSIS
+--------
+[verse]
+'git replace' [-f] <object> <replacement>
+'git replace' -d <object>...
+'git replace' -l [<pattern>]
+
+DESCRIPTION
+-----------
+Adds a 'replace' reference in `.git/refs/replace/`
+
+The name of the 'replace' reference is the SHA1 of the object that is
+replaced. The content of the 'replace' reference is the SHA1 of the
+replacement object.
+
+Unless `-f` is given, the 'replace' reference must not yet exist in
+`.git/refs/replace/` directory.
+
+Replacement references will be used by default by all git commands
+except those doing reachability traversal (prune, pack transfer and
+fsck).
+
+It is possible to disable use of replacement references for any
+command using the `--no-replace-objects` option just after 'git'.
+
+For example if commit 'foo' has been replaced by commit 'bar':
+
+------------------------------------------------
+$ git --no-replace-objects cat-file commit foo
+------------------------------------------------
+
+shows information about commit 'foo', while:
+
+------------------------------------------------
+$ git cat-file commit foo
+------------------------------------------------
+
+shows information about commit 'bar'.
+
+The 'GIT_NO_REPLACE_OBJECTS' environment variable can be set to
+achieve the same effect as the `--no-replace-objects` option.
+
+OPTIONS
+-------
+-f::
+       If an existing replace ref for the same object exists, it will
+       be overwritten (instead of failing).
+
+-d::
+       Delete existing replace refs for the given objects.
+
+-l <pattern>::
+       List replace refs for objects that match the given pattern (or
+       all if no pattern is given).
+       Typing "git replace" without arguments, also lists all replace
+       refs.
+
+BUGS
+----
+Comparing blobs or trees that have been replaced with those that
+replace them will not work properly. And using `git reset --hard` to
+go back to a replaced commit will move the branch to the replacement
+commit instead of the replaced commit.
+
+There may be other problems when using 'git rev-list' related to
+pending objects. And of course things may break if an object of one
+type is replaced by an object of another type (for example a blob
+replaced by a commit).

+REMOVING FILES THAT HAVE DISAPPEARED FROM THE FILESYSTEM
+--------------------------------------------------------
+There is no option for `git rm` to remove from the index only
+the paths that have disappeared from the filesystem. However,
+depending on the use case, there are several ways that can be
+done.
+
+Using "git commit -a"
+~~~~~~~~~~~~~~~~~~~~~
+If you intend that your next commit should record all modifications
+of tracked files in the working tree and record all removals of
+files that have been removed from the working tree with `rm`
+(as opposed to `git rm`), use `git commit -a`, as it will
+automatically notice and record all removals.  You can also have a
+similar effect without committing by using `git add -u`.
+
+Using "git add -A"
+~~~~~~~~~~~~~~~~~~
+When accepting a new code drop for a vendor branch, you probably
+want to record both the removal of paths and additions of new paths
+as well as modifications of existing paths.
+
+Typically you would first remove all tracked files from the working
+tree using this command:
+
+----------------
+git ls-files -z | xargs -0 rm -f
+----------------
+
+and then "untar" the new code in the working tree. Alternately
+you could "rsync" the changes into the working tree.
+
+After that, the easiest way to record all removals, additions, and
+modifications in the working tree is:
+
+----------------
+git add -A
+----------------
+
+See linkgit:git-add[1].
+
+Other ways
+~~~~~~~~~~
+If all you really want to do is to remove from the index the files
+that are no longer present in the working tree (perhaps because
+your working tree is dirty so that you cannot use `git commit -a`),
+use the following command:
+
+----------------
+git diff --name-only --diff-filter=D -z | xargs -0 git rm --cached

 the status.relativePaths config option below.

+Skip-worktree bit
+-----------------
+
+Skip-worktree bit can be defined in one (long) sentence: When reading
+an entry, if it is marked as skip-worktree, then Git pretends its
+working directory version is up to date and read the index version
+instead.
+
+To elaborate, "reading" means checking for file existence, reading
+file attributes or file content. The working directory version may be
+present or absent. If present, its content may match against the index
+version or not. Writing is not affected by this bit, content safety
+is still first priority. Note that Git _can_ update working directory
+file, that is marked skip-worktree, if it is safe to do so (i.e.
+working directory version matches index version)
+
+Although this bit looks similar to assume-unchanged bit, its goal is
+different from assume-unchanged bit's. Skip-worktree also takes
+precedence over assume-unchanged bit when both are set.

+Branch management for a release
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Assuming you are using the merge approach discussed above, when you
+are releasing your project you will need to do some additional branch
+management work.
+
+A feature release is created from the 'master' branch, since 'master'
+tracks the commits that should go into the next feature release.
+
+The 'master' branch is supposed to be a superset of 'maint'. If this
+condition does not hold, then 'maint' contains some commits that
+are not included on 'master'. The fixes represented by those commits
+will therefore not be included in your feature release.
+
+To verify that 'master' is indeed a superset of 'maint', use git log:
+
+.Verify 'master' is a superset of 'maint'
+[caption="Recipe: "]
+=====================================
+`git log master..maint`
+=====================================
+
+This command should not list any commits.  Otherwise, check out
+'master' and merge 'maint' into it.
+
+Now you can proceed with the creation of the feature release. Apply a
+tag to the tip of 'master' indicating the release version:
+
+.Release tagging
+[caption="Recipe: "]
+=====================================
+`git tag -s -m "GIT X.Y.Z" vX.Y.Z master`
+=====================================
+
+You need to push the new tag to a public git server (see
+"DISTRIBUTED WORKFLOWS" below). This makes the tag available to
+others tracking your project. The push could also trigger a
+post-update hook to perform release-related items such as building
+release tarballs and preformatted documentation pages.
+
+Similarly, for a maintenance release, 'maint' is tracking the commits
+to be released. Therefore, in the steps above simply tag and push
+'maint' rather than 'master'.
+
+
+Maintenance branch management after a feature release
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After a feature release, you need to manage your maintenance branches.
+
+First, if you wish to continue to release maintenance fixes for the
+feature release made before the recent one, then you must create
+another branch to track commits for that previous release.
+
+To do this, the current maintenance branch is copied to another branch
+named with the previous release version number (e.g. maint-X.Y.(Z-1)
+where X.Y.Z is the current release).
+
+.Copy maint
+[caption="Recipe: "]
+=====================================
+`git branch maint-X.Y.(Z-1) maint`
+=====================================
+
+The 'maint' branch should now be fast-forwarded to the newly released
+code so that maintenance fixes can be tracked for the current release:
+
+.Update maint to new release
+[caption="Recipe: "]
+=====================================
+* `git checkout maint`
+* `git merge --ff-only master`
+=====================================
+
+If the merge fails because it is not a fast-forward, then it is
+possible some fixes on 'maint' were missed in the feature release.
+This will not happen if the content of the branches was verified as
+described in the previous section.
+
+
+Branch management for next and pu after a feature release
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+After a feature release, the integration branch 'next' may optionally be
+rewound and rebuilt from the tip of 'master' using the surviving
+topics on 'next':
+
+.Rewind and rebuild next
+[caption="Recipe: "]
+=====================================
+* `git checkout next`
+* `git reset --hard master`
+* `git merge ai/topic_in_next1`
+* `git merge ai/topic_in_next2`
+* ...
+=====================================
+
+The advantage of doing this is that the history of 'next' will be
+clean. For example, some topics merged into 'next' may have initially
+looked promising, but were later found to be undesirable or premature.
+In such a case, the topic is reverted out of 'next' but the fact
+remains in the history that it was once merged and reverted. By
+recreating 'next', you give another incarnation of such topics a clean
+slate to retry, and a feature release is a good point in history to do
+so.
+
+If you do this, then you should make a public announcement indicating
+that 'next' was rewound and rebuilt.
+
+The same rewind and rebuild process may be followed for 'pu'. A public
+announcement is not necessary since 'pu' is a throw-away branch, as
+described above.

 MERGE STRATEGIES

+==============
+
+NOME
+----
+gittutorial - Um tutorial de introdução ao git (para versão 1.5.1 ou mais nova)
+
+SINOPSE
+--------
+git *
+
+DESCRIÇÃO
+-----------
+
+Este tutorial explica como importar um novo projeto para o git,
+adicionar mudanças a ele, e compartilhar mudanças com outros
+desenvolvedores.
+
+Se, ao invés disso, você está interessado primariamente em usar git para
+obter um projeto, por exemplo, para testar a última versão, você pode
+preferir começar com os primeiros dois capítulos de
+link:user-manual.html[O Manual do Usuário Git].
+
+Primeiro, note que você pode obter documentação para um comando como
+`git log --graph` com:
+
+------------------------------------------------
+$ man git-log
+------------------------------------------------
+
+ou:
+
+------------------------------------------------
+$ git help log
+------------------------------------------------
+
+Com a última forma, você pode usar o visualizador de manual de sua
+escolha; veja linkgit:git-help[1] para maior informação.
+
+É uma boa idéia informar ao git seu nome e endereço público de email
+antes de fazer qualquer operação. A maneira mais fácil de fazê-lo é:
+
+------------------------------------------------
+$ git config --global user.name "Seu Nome Vem Aqui"
+$ git config --global user.email voce@seudominio.exemplo.com
+------------------------------------------------
+
+
+Importando um novo projeto
+-----------------------
+
+Assuma que você tem um tarball project.tar.gz com seu trabalho inicial.
+Você pode colocá-lo sob controle de revisão git da seguinte forma:
+
+------------------------------------------------
+$ tar xzf project.tar.gz
+$ cd project
+$ git init
+------------------------------------------------
+
+Git irá responder
+
+------------------------------------------------
+Initialized empty Git repository in .git/
+------------------------------------------------
+
+Agora que você iniciou seu diretório de trabalho, você deve ter notado que um
+novo diretório foi criado com o nome de ".git".
+
+A seguir, diga ao git para gravar um instantâneo do conteúdo de todos os
+arquivos sob o diretório atual (note o '.'), com 'git-add':
+
+------------------------------------------------
+$ git add .
+------------------------------------------------
+
+Este instantâneo está agora armazenado em uma área temporária que o git
+chama de "index" ou índice. Você pode armazenar permanentemente o
+conteúdo do índice no repositório com 'git-commit':
+
+------------------------------------------------
+$ git commit
+------------------------------------------------
+
+Isto vai te pedir por uma mensagem de commit. Você agora gravou sua
+primeira versão de seu projeto no git.
+
+Fazendo mudanças
+--------------
+
+Modifique alguns arquivos, e, então, adicione seu conteúdo atualizado ao
+índice:
+
+------------------------------------------------
+$ git add file1 file2 file3
+------------------------------------------------
+
+Você está agora pronto para fazer o commit. Você pode ver o que está
+para ser gravado usando 'git-diff' com a opção --cached:
+
+------------------------------------------------
+$ git diff --cached
+------------------------------------------------
+
+(Sem --cached, o comando 'git-diff' irá te mostrar quaisquer mudanças
+que você tenha feito mas ainda não adicionou ao índice.) Você também
+pode obter um breve sumário da situação com 'git-status':
+
+------------------------------------------------
+$ git status
+# On branch master
+# Changes to be committed:
+#   (use "git reset HEAD <file>..." to unstage)
+#
+#      modified:   file1
+#      modified:   file2
+#      modified:   file3
+#
+------------------------------------------------
+
+Se você precisar fazer qualquer outro ajuste, faça-o agora, e, então,
+adicione qualquer conteúdo modificado ao índice. Finalmente, grave suas
+mudanças com:
+
+------------------------------------------------
+$ git commit
+------------------------------------------------
+
+Ao executar esse comando, ele irá te pedir uma mensagem descrevendo a mudança,
+e, então, irá gravar a nova versão do projeto.
+
+Alternativamente, ao invés de executar 'git-add' antes, você pode usar
+
+------------------------------------------------
+$ git commit -a
+------------------------------------------------
+
+o que irá automaticamente notar quaisquer arquivos modificados (mas não
+novos), adicioná-los ao índices, e gravar, tudo em um único passo.
+
+Uma nota em mensagens de commit: Apesar de não ser exigido, é uma boa
+idéia começar a mensagem com uma simples e curta (menos de 50
+caracteres) linha sumarizando a mudança, seguida de uma linha em branco
+e, então, uma descrição mais detalhada. Ferramentas que transformam
+commits em email, por exemplo, usam a primeira linha no campo de
+cabeçalho "Subject:" e o resto no corpo.
+
+Git rastreia conteúdo, não arquivos
+----------------------------
+
+Muitos sistemas de controle de revisão provêem um comando `add` que diz
+ao sistema para começar a rastrear mudanças em um novo arquivo. O
+comando `add` do git faz algo mais simples e mais poderoso: 'git-add' é
+usado tanto para arquivos novos e arquivos recentemente modificados, e
+em ambos os casos, ele tira o instantâneo dos arquivos dados e armazena
+o conteúdo no índice, pronto para inclusão do próximo commit.
+
+Visualizando a história do projeto
+-----------------------
+
+Em qualquer ponto você pode visualizar a história das suas mudanças
+usando
+
+------------------------------------------------
+$ git log
+------------------------------------------------
+
+Se você também quiser ver a diferença completa a cada passo, use
+
+------------------------------------------------
+$ git log -p
+------------------------------------------------
+
+Geralmente, uma visão geral da mudança é útil para ter a sensação de
+cada passo
+
+------------------------------------------------
+$ git log --stat --summary
+------------------------------------------------
+
+Gerenciando "branches"/ramos
+-----------------
+
+Um simples repositório git pode manter múltiplos ramos de
+desenvolvimento. Para criar um novo ramo chamado "experimental", use
+
+------------------------------------------------
+$ git branch experimental
+------------------------------------------------
+
+Se você executar agora
+
+------------------------------------------------
+$ git branch
+------------------------------------------------
+
+você vai obter uma lista de todos os ramos existentes:
+
+------------------------------------------------
+  experimental
+* master
+------------------------------------------------
+
+O ramo "experimental" é o que você acaba de criar, e o ramo "master" é o
+ramo padrão que foi criado pra você automaticamente. O asterisco marca
+o ramo em que você está atualmente; digite
+
+------------------------------------------------
+$ git checkout experimental
+------------------------------------------------
+
+para mudar para o ramo experimental. Agora edite um arquivo, grave a
+mudança, e mude de volta para o ramo master:
+
+------------------------------------------------
+(edita arquivo)
+$ git commit -a
+$ git checkout master
+------------------------------------------------
+
+Verifique que a mudança que você fez não está mais visível, já que ela
+foi feita no ramo experimental e você está de volta ao ramo master.
+
+Você pode fazer uma mudança diferente no ramo master:
+
+------------------------------------------------
+(edit file)
+$ git commit -a
+------------------------------------------------
+
+neste ponto, os dois ramos divergiram, com diferentes mudanças feitas em
+cada um. Para unificar as mudanças feitas no experimental para o
+master, execute
+
+------------------------------------------------
+$ git merge experimental
+------------------------------------------------
+
+Se as mudanças não conflitarem, estará pronto. Se existirem conflitos,
+marcadores serão deixados nos arquivos problemáticos exibindo o
+conflito;
+
+------------------------------------------------
+$ git diff
+------------------------------------------------
+
+vai exibir isto. Após você editar os arquivos para resolver os

+irá gravar o resultado da unificação. Finalmente,
+
+------------------------------------------------
+$ gitk
+------------------------------------------------
+
+vai mostrar uma bela representação gráfica da história resultante.
+
+Neste ponto você pode remover seu ramo experimental com
+
+------------------------------------------------
+$ git branch -d experimental
+------------------------------------------------
+
+Este comando garante que as mudanças no ramo experimental já estão no
+ramo atual.
+
+Se você desenvolve em um ramo ideia-louca, e se arrepende, você pode
+sempre remover o ramo com
+
+-------------------------------------
+$ git branch -D ideia-louca
+-------------------------------------
+
+Ramos são baratos e fáceis, então isto é uma boa maneira de experimentar
+alguma coisa.
+
+Usando git para colaboração
+---------------------------
+
+Suponha que Alice começou um novo projeto com um repositório git em
+/home/alice/project, e que Bob, que tem um diretório home na mesma
+máquina, quer contribuir.
+
+Bob começa com:
+
+------------------------------------------------
+bob$ git clone /home/alice/project myrepo
+------------------------------------------------
+
+Isso cria um novo diretório "myrepo" contendo um clone do repositório de
+Alice. O clone está no mesmo pé que o projeto original, possuindo sua
+própria cópia da história do projeto original.
+
+Bob então faz algumas mudanças e as grava:
+
+------------------------------------------------
+(editar arquivos)
+bob$ git commit -a
+(repetir conforme necessário)
+------------------------------------------------
+
+Quanto está pronto, ele diz a Alice para puxar as mudanças do
+repositório em /home/bob/myrepo. Ela o faz com:
+
+------------------------------------------------
+alice$ cd /home/alice/project
+alice$ git pull /home/bob/myrepo master
+------------------------------------------------
+
+Isto unifica as mudanças do ramo "master" do Bob ao ramo atual de Alice.
+Se Alice fez suas próprias mudanças no intervalo, ela, então, pode
+precisar corrigir manualmente quaisquer conflitos. (Note que o argumento
+"master" no comando acima é, de fato, desnecessário, já que é o padrão.)
+
+O comando "pull" executa, então, duas operações: ele obtém mudanças de
+um ramo remoto, e, então, as unifica no ramo atual.
+
+Note que, em geral, Alice gostaria que suas mudanças locais fossem
+gravadas antes de iniciar este "pull". Se o trabalho de Bob conflita
+com o que Alice fez desde que suas histórias se ramificaram, Alice irá
+usar seu diretório de trabalho e o índice para resolver conflitos, e
+mudanças locais existentes irão interferir com o processo de resolução
+de conflitos (git ainda irá realizar a obtenção mas irá se recusar a
+unificar --- Alice terá que se livrar de suas mudanças locais de alguma
+forma e puxar de novo quando isso acontecer).
+
+Alice pode espiar o que Bob fez sem unificar primeiro, usando o comando
+"fetch"; isto permite Alice inspecionar o que Bob fez, usando um símbolo
+especial "FETCH_HEAD", com o fim de determinar se ele tem alguma coisa
+que vale puxar, assim:
+
+------------------------------------------------
+alice$ git fetch /home/bob/myrepo master
+alice$ git log -p HEAD..FETCH_HEAD
+------------------------------------------------
+
+Esta operação é segura mesmo se Alice tem mudanças locais não gravadas.
+A notação de intervalo "HEAD..FETCH_HEAD" significa mostrar tudo que é
+alcançável de FETCH_HEAD mas exclua tudo o que é alcançável de HEAD.
+Alice já sabe tudo que leva a seu estado atual (HEAD), e revisa o que Bob
+tem em seu estado (FETCH_HEAD) que ela ainda não viu com esse comando.
+
+Se Alice quer visualizar o que Bob fez desde que suas histórias se
+ramificaram, ela pode disparar o seguinte comando:
+
+------------------------------------------------
+$ gitk HEAD..FETCH_HEAD
+------------------------------------------------
+
+Isto usa a mesma notação de intervalo que vimos antes com 'git log'.
+
+Alice pode querer ver o que ambos fizeram desde que ramificaram. Ela
+pode usar a forma com três pontos ao invés da forma com dois pontos:
+
+------------------------------------------------
+$ gitk HEAD...FETCH_HEAD
+------------------------------------------------
+
+Isto significa "mostre tudo que é alcançável de qualquer um deles, mas
+exclua tudo que é alcançável a partir de ambos".
+
+Por favor, note que essas notações de intervalo podem ser usadas tanto
+com gitk quanto com "git log".
+
+Após inspecionar o que Bob fez, se não há nada urgente, Alice pode
+decidir continuar trabalhando sem puxar de Bob. Se a história de Bob
+tem alguma coisa que Alice precisa imediatamente, Alice pode optar por
+separar seu trabalho em progresso primeiro, fazer um "pull", e, então,
+finalmente, retomar seu trabalho em progresso em cima da história
+resultante.
+
+Quando você está trabalhando em um pequeno grupo unido, não é incomum
+interagir com o mesmo repositório várias e várias vezes. Definindo um
+repositório remoto antes de tudo, você pode fazê-lo mais facilmente:
+
+------------------------------------------------
+alice$ git remote add bob /home/bob/myrepo
+------------------------------------------------
+
+Com isso, Alice pode executar a primeira parte da operação "pull" usando
+o comando 'git-fetch' sem unificar suas mudanças com seu próprio ramo,
+usando:
+
+-------------------------------------
+alice$ git fetch bob
+-------------------------------------
+
+Diferente da forma longa, quando Alice obteve de Bob usando um
+repositório remoto antes definido com 'git-remote', o que foi obtido é
+armazenado em um ramo remoto, neste caso `bob/master`. Então, após isso:
+
+-------------------------------------
+alice$ git log -p master..bob/master
+-------------------------------------
+
+mostra uma lista de todas as mudanças que Bob fez desde que ramificou do
+ramo master de Alice.
+
+Após examinar essas mudanças, Alice pode unificá-las em seu ramo master:
+
+-------------------------------------
+alice$ git merge bob/master
+-------------------------------------
+
+Esse `merge` pode também ser feito puxando de seu próprio ramo remoto,
+assim:
+
+-------------------------------------
+alice$ git pull . remotes/bob/master
+-------------------------------------
+
+Note que 'git pull' sempre unifica ao ramo atual, independente do que
+mais foi passado na linha de comando.
+
+Depois, Bob pode atualizar seu repositório com as últimas mudanças de
+Alice, usando
+
+-------------------------------------
+bob$ git pull
+-------------------------------------
+
+Note que ele não precisa dar o caminho do repositório de Alice; quando
+Bob clonou seu repositório, o git armazenou a localização de seu
+repositório na configuração do mesmo, e essa localização é usada
+para puxar:
+
+-------------------------------------
+bob$ git config --get remote.origin.url
+/home/alice/project
+-------------------------------------
+
+(A configuração completa criada por 'git-clone' é visível usando `git
+config -l`, e a página de manual linkgit:git-config[1] explica o
+significado de cada opção.)
+
+Git também mantém uma cópia limpa do ramo master de Alice sob o nome
+"origin/master":
+
+-------------------------------------
+bob$ git branch -r
+  origin/master
+-------------------------------------
+
+Se Bob decidir depois em trabalhar em um host diferente, ele ainda pode
+executar clones e puxar usando o protocolo ssh:
+
+-------------------------------------
+bob$ git clone alice.org:/home/alice/project myrepo
+-------------------------------------
+
+Alternativamente, o git tem um protocolo nativo, ou pode usar rsync ou
+http; veja linkgit:git-pull[1] para detalhes.
+
+Git pode também ser usado em um modo parecido com CVS, com um
+repositório central para o qual vários usuários empurram modificações;
+veja linkgit:git-push[1] e linkgit:gitcvs-migration[7].
+
+Explorando história
+-----------------
+
+A história no git é representada como uma série de commits
+interrelacionados. Nós já vimos que o comando 'git-log' pode listar
+esses commits. Note que a primeira linha de cada entrada no log também
+dá o nome para o commit:
+
+-------------------------------------
+$ git log
+commit c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
+Author: Junio C Hamano <junkio@cox.net>
+Date:   Tue May 16 17:18:22 2006 -0700
+
+    merge-base: Clarify the comments on post processing.
+-------------------------------------
+
+Nós podemos dar este nome ao 'git-show' para ver os detalhes sobre este
+commit.
+
+-------------------------------------
+$ git show c82a22c39cbc32576f64f5c6b3f24b99ea8149c7
+-------------------------------------
+
+Mas há outras formas de se referir aos commits. Você pode usar qualquer
+parte inicial do nome que seja longo o bastante para identificar
+unicamente o commit:
+
+-------------------------------------
+$ git show c82a22c39c  # os primeiros caracteres do nome são o bastante
+                       # usualmente
+$ git show HEAD                # a ponta do ramo atual
+$ git show experimental        # a ponta do ramo "experimental"
+-------------------------------------
+
+Todo commit normalmente tem um commit "pai" que aponta para o estado
+anterior do projeto:
+
+-------------------------------------
+$ git show HEAD^  # para ver o pai de HEAD
+$ git show HEAD^^ # para ver o avô de HEAD
+$ git show HEAD~4 # para ver o trisavô de HEAD
+-------------------------------------
+
+Note que commits de unificação podem ter mais de um pai:
+
+-------------------------------------
+$ git show HEAD^1 # mostra o primeiro pai de HEAD (o mesmo que HEAD^)
+$ git show HEAD^2 # mostra o segundo pai de HEAD
+-------------------------------------
+
+Você também pode dar aos commits nomes à sua escolha; após executar
+
+-------------------------------------
+$ git tag v2.5 1b2e1d63ff
+-------------------------------------
+
+você pode se referir a 1b2e1d63ff pelo nome "v2.5". Se você pretende
+compartilhar esse nome com outras pessoas (por exemplo, para identificar
+uma versão de lançamento), você deveria criar um objeto "tag", e talvez
+assiná-lo; veja linkgit:git-tag[1] para detalhes.
+
+Qualquer comando git que precise conhecer um commit pode receber
+quaisquer desses nomes. Por exemplo:
+
+-------------------------------------
+$ git diff v2.5 HEAD    # compara o HEAD atual com v2.5
+$ git branch stable v2.5 # inicia um novo ramo chamado "stable" baseado
+                        # em v2.5
+$ git reset --hard HEAD^ # reseta seu ramo atual e seu diretório de
+                        # trabalho a seu estado em HEAD^
+-------------------------------------
+
+Seja cuidadoso com o último comando: além de perder quaisquer mudanças
+em seu diretório de trabalho, ele também remove todos os commits
+posteriores desse ramo. Se esse ramo é o único ramo contendo esses
+commits, eles serão perdidos. Também, não use 'git-reset' num ramo
+publicamente visível de onde outros desenvolvedores puxam, já que vai
+forçar unificações desnecessárias para que outros desenvolvedores limpem
+a história. Se você precisa desfazer mudanças que você empurrou, use
+'git-revert' no lugar.
+
+O comando 'git-grep' pode buscar strings em qualquer versão de seu
+projeto, então
+
+-------------------------------------
+$ git grep "hello" v2.5
+-------------------------------------
+
+procura por todas as ocorrências de "hello" em v2.5.
+
+Se você deixar de fora o nome do commit, 'git-grep' irá procurar
+quaisquer dos arquivos que ele gerencia no diretório corrente. Então
+
+-------------------------------------
+$ git grep "hello"
+-------------------------------------
+
+é uma forma rápida de buscar somente os arquivos que são rastreados pelo
+git.
+
+Muitos comandos git também recebem um conjunto de commits, o que pode
+ser especificado de várias formas. Aqui estão alguns exemplos com 'git-log':
+
+-------------------------------------
+$ git log v2.5..v2.6            # commits entre v2.5 e v2.6
+$ git log v2.5..                # commits desde v2.5
+$ git log --since="2 weeks ago" # commits das últimas 2 semanas
+$ git log v2.5.. Makefile       # commits desde v2.5 que modificam
+                               # Makefile
+-------------------------------------
+
+Você também pode dar ao 'git-log' um "intervalo" de commits onde o
+primeiro não é necessariamente um ancestral do segundo; por exemplo, se
+as pontas dos ramos "stable" e "master" divergiram de um commit
+comum algum tempo atrás, então
+
+-------------------------------------
+$ git log stable..master
+-------------------------------------
+
+irá listar os commits feitos no ramo "master" mas não no ramo
+"stable", enquanto
+
+-------------------------------------
+$ git log master..stable
+-------------------------------------
+
+irá listar a lista de commits feitos no ramo "stable" mas não no ramo
+"master".
+
+O comando 'git-log' tem uma fraqueza: ele precisa mostrar os commits em
+uma lista. Quando a história tem linhas de desenvolvimento que
+divergiram e então foram unificadas novamente, a ordem em que 'git-log'
+apresenta essas mudanças é irrelevante.
+
+A maioria dos projetos com múltiplos contribuidores (como o kernel
+Linux, ou o próprio git) tem unificações frequentes, e 'gitk' faz um
+trabalho melhor de visualizar sua história. Por exemplo,
+
+-------------------------------------
+$ gitk --since="2 weeks ago" drivers/
+-------------------------------------
+
+permite a você navegar em quaisquer commits desde as últimas duas semanas
+de commits que modificaram arquivos sob o diretório "drivers". (Nota:
+você pode ajustar as fontes do gitk segurando a tecla control enquanto
+pressiona "-" ou "+".)
+
+Finalmente, a maioria dos comandos que recebem nomes de arquivo permitirão
+também, opcionalmente, preceder qualquer nome de arquivo por um
+commit, para especificar uma versão particular do arquivo:
+
+-------------------------------------
+$ git diff v2.5:Makefile HEAD:Makefile.in
+-------------------------------------
+
+Você pode usar 'git-show' para ver tal arquivo:
+
+-------------------------------------
+$ git show v2.5:Makefile
+-------------------------------------
+
+Próximos passos
+----------
+
+Este tutorial deve ser o bastante para operar controle de revisão
+distribuído básico para seus projetos. No entanto, para entender
+plenamente a profundidade e o poder do git você precisa entender duas
+idéias simples nas quais ele se baseia:
+
+  * A base de objetos é um sistema bem elegante usado para armazenar a
+    história de seu projeto--arquivos, diretórios, e commits.
+
+  * O arquivo de índice é um cache do estado de uma árvore de diretório,
+    usado para criar commits, restaurar diretórios de trabalho, e
+    armazenar as várias árvores envolvidas em uma unificação.
+
+A parte dois deste tutorial explica a base de objetos, o arquivo de
+índice, e algumas outras coisinhas que você vai precisar pra usar o
+máximo do git. Você pode encontrá-la em linkgit:gittutorial-2[7].
+
+Se você não quiser continuar com o tutorial agora nesse momento, algumas
+outras digressões que podem ser interessantes neste ponto são:
+
+  * linkgit:git-format-patch[1], linkgit:git-am[1]: Estes convertem
+    séries de commits em patches para email, e vice-versa, úteis para
+    projetos como o kernel Linux que dependem fortemente de patches
+    enviados por email.
+
+  * linkgit:git-bisect[1]: Quando há uma regressão em seu projeto, uma
+    forma de rastrear um bug é procurando pela história para encontrar o
+    commit culpado. Git bisect pode ajudar a executar uma busca binária
+    por esse commit. Ele é inteligente o bastante para executar uma
+    busca próxima da ótima mesmo no caso de uma história complexa
+    não-linear com muitos ramos unificados.
+
+  * link:everyday.html[GIT diariamente com 20 e tantos comandos]
+
+  * linkgit:gitcvs-migration[7]: Git para usuários de CVS.

 hash API
 ========
 
-Talk about <hash.h>
+The hash API is a collection of simple hash table functions. Users are expected
+to implement their own hashing.
 
-(Linus)
+Data Structures
+---------------
+
+`struct hash_table`::
+
+       The hash table structure. The `array` member points to the hash table
+       entries. The `size` member counts the total number of valid and invalid
+       entries in the table. The `nr` member keeps track of the number of
+       valid entries.
+
+`struct hash_table_entry`::
+
+       An opaque structure representing an entry in the hash table. The `hash`
+       member is the entry's hash key and the `ptr` member is the entry's
+       value.
+
+Functions
+---------
+
+`init_hash`::
+
+       Initialize the hash table.
+
+`free_hash`::
+
+       Release memory associated with the hash table.
+
+`insert_hash`::
+
+       Insert a pointer into the hash table. If an entry with that hash
+       already exists, a pointer to the existing entry's value is returned.
+       Otherwise NULL is returned.  This allows callers to implement
+       chaining, etc.
+
+`lookup_hash`::
+
+       Lookup an entry in the hash table. If an entry with that hash exists
+       the entry's value is returned. Otherwise NULL is returned.
+
+`for_each_hash`::
+
+       Call a function for each entry in the hash table. The function is
+       expected to take the entry's value as its only argument and return an
+       int. If the function returns a negative int the loop is aborted
+       immediately.  Otherwise, the return value is accumulated and the sum
+       returned upon completion of the loop.

+       mode.
+
+`struct tree_desc`::
+
+       A semi-opaque data structure used to maintain the current state of the
+       walk.
++
+* `buffer` is a pointer into the memory representation of the tree. It always
+points at the current entry being visited.
+
+* `size` counts the number of bytes left in the `buffer`.
+
+* `entry` points to the current entry being visited.
+
+`struct traverse_info`::
+
+       A structure used to maintain the state of a traversal.
++
+* `prev` points to the traverse_info which was used to descend into the
+current tree. If this is the top-level tree `prev` will point to
+a dummy traverse_info.
+
+* `name` is the entry for the current tree (if the tree is a subtree).
+
+* `pathlen` is the length of the full path for the current tree.
+
+* `conflicts` can be used by callbacks to maintain directory-file conflicts.
+
+* `fn` is a callback called for each entry in the tree. See Traversing for more
+information.
+
+* `data` can be anything the `fn` callback would want to use.
+
+Initializing
+------------
+
+`init_tree_desc`::
+
+       Initialize a `tree_desc` and decode its first entry. The buffer and
+       size parameters are assumed to be the same as the buffer and size
+       members of `struct tree`.
+
+`fill_tree_descriptor`::
+
+       Initialize a `tree_desc` and decode its first entry given the sha1 of
+       a tree. Returns the `buffer` member if the sha1 is a valid tree
+       identifier and NULL otherwise.
+
+`setup_traverse_info`::
+
+       Initialize a `traverse_info` given the pathname of the tree to start
+       traversing from. The `base` argument is assumed to be the `path`
+       member of the `name_entry` being recursed into unless the tree is a
+       top-level tree in which case the empty string ("") is used.
+
+Walking
+-------
+
+`tree_entry`::
+
+       Visit the next entry in a tree. Returns 1 when there are more entries
+       left to visit and 0 when all entries have been visited. This is
+       commonly used in the test of a while loop.
+
+`tree_entry_len`::
+
+       Calculate the length of a tree entry's pathname. This utilizes the
+       memory structure of a tree entry to avoid the overhead of using a
+       generic strlen().
+
+`update_tree_entry`::
+
+       Walk to the next entry in a tree. This is commonly used in conjunction
+       with `tree_entry_extract` to inspect the current entry.
+
+`tree_entry_extract`::
+
+       Decode the entry currently being visited (the one pointed to by
+       `tree_desc's` `entry` member) and return the sha1 of the entry. The
+       `pathp` and `modep` arguments are set to the entry's pathname and mode
+       respectively.
+
+`get_tree_entry`::
+
+       Find an entry in a tree given a pathname and the sha1 of a tree to
+       search. Returns 0 if the entry is found and -1 otherwise. The third
+       and fourth parameters are set to the entry's sha1 and mode
+       respectively.
+
+Traversing
+----------
+
+`traverse_trees`::
+
+       Traverse `n` number of trees in parallel. The `fn` callback member of
+       `traverse_info` is called once for each tree entry.
+
+`traverse_callback_t`::
+       The arguments passed to the traverse callback are as follows:
++
+* `n` counts the number of trees being traversed.
+
+* `mask` has its nth bit set if something exists in the nth entry.
+
+* `dirmask` has its nth bit set if the nth tree's entry is a directory.
+
+* `entry` is an array of size `n` where the nth entry is from the nth tree.
+
+* `info` maintains the state of the traversal.
+
++
+Returning a negative value will terminate the traversal. Otherwise the
+return value is treated as an update mask. If the nth bit is set the nth tree
+will be updated and if the bit is not set the nth tree entry will be the
+same in the next callback invocation.
+
+`make_traverse_path`::
+
+       Generate the full pathname of a tree entry based from the root of the
+       traversal. For example, if the traversal has recursed into another
+       tree named "bar" the pathname of an entry "baz" in the "bar"
+       tree would be "bar/baz".
+
+`traverse_path_len`::
+
+       Calculate the length of a pathname returned by `make_traverse_path`.
+       This utilizes the memory structure of a tree entry to avoid the
+       overhead of using a generic strlen().

+Packfile transfer protocols
+===========================
+
+Git supports transferring data in packfiles over the ssh://, git:// and
+file:// transports.  There exist two sets of protocols, one for pushing
+data from a client to a server and another for fetching data from a
+server to a client.  All three transports (ssh, git, file) use the same
+protocol to transfer data.
+
+The processes invoked in the canonical Git implementation are 'upload-pack'
+on the server side and 'fetch-pack' on the client side for fetching data;
+then 'receive-pack' on the server and 'send-pack' on the client for pushing
+data.  The protocol functions to have a server tell a client what is
+currently on the server, then for the two to negotiate the smallest amount
+of data to send in order to fully update one or the other.
+
+Transports
+----------
+There are three transports over which the packfile protocol is
+initiated.  The Git transport is a simple, unauthenticated server that
+takes the command (almost always 'upload-pack', though Git
+servers can be configured to be globally writable, in which 'receive-
+pack' initiation is also allowed) with which the client wishes to
+communicate and executes it and connects it to the requesting
+process.
+
+In the SSH transport, the client just runs the 'upload-pack'
+or 'receive-pack' process on the server over the SSH protocol and then
+communicates with that invoked process over the SSH connection.
+
+The file:// transport runs the 'upload-pack' or 'receive-pack'
+process locally and communicates with it over a pipe.
+
+Git Transport
+-------------
+
+The Git transport starts off by sending the command and repository
+on the wire using the pkt-line format, followed by a NUL byte and a
+hostname paramater, terminated by a NUL byte.
+
+   0032git-upload-pack /project.git\0host=myserver.com\0
+
+--
+   git-proto-request = request-command SP pathname NUL [ host-parameter NUL ]
+   request-command   = "git-upload-pack" / "git-receive-pack" /
+                      "git-upload-archive"   ; case sensitive
+   pathname          = *( %x01-ff ) ; exclude NUL
+   host-parameter    = "host=" hostname [ ":" port ]
+--
+
+Only host-parameter is allowed in the git-proto-request. Clients
+MUST NOT attempt to send additional parameters. It is used for the
+git-daemon name based virtual hosting.  See --interpolated-path
+option to git daemon, with the %H/%CH format characters.
+
+Basically what the Git client is doing to connect to an 'upload-pack'
+process on the server side over the Git protocol is this:
+
+   $ echo -e -n \
+     "0039git-upload-pack /schacon/gitbook.git\0host=example.com\0" |
+     nc -v example.com 9418
+
+
+SSH Transport
+-------------
+
+Initiating the upload-pack or receive-pack processes over SSH is
+executing the binary on the server via SSH remote execution.
+It is basically equivalent to running this:
+
+   $ ssh git.example.com "git-upload-pack '/project.git'"
+
+For a server to support Git pushing and pulling for a given user over
+SSH, that user needs to be able to execute one or both of those
+commands via the SSH shell that they are provided on login.  On some
+systems, that shell access is limited to only being able to run those
+two commands, or even just one of them.
+
+In an ssh:// format URI, it's absolute in the URI, so the '/' after
+the host name (or port number) is sent as an argument, which is then
+read by the remote git-upload-pack exactly as is, so it's effectively
+an absolute path in the remote filesystem.
+
+       git clone ssh://user@example.com/project.git
+                   |
+                   v
+    ssh user@example.com "git-upload-pack '/project.git'"
+
+In a "user@host:path" format URI, its relative to the user's home
+directory, because the Git client will run:
+
+     git clone user@example.com:project.git
+                   |
+                   v
+  ssh user@example.com "git-upload-pack 'project.git'"
+
+The exception is if a '~' is used, in which case
+we execute it without the leading '/'.
+
+      ssh://user@example.com/~alice/project.git,
+                    |
+                    v
+   ssh user@example.com "git-upload-pack '~alice/project.git'"
+
+A few things to remember here:
+
+- The "command name" is spelled with dash (e.g. git-upload-pack), but
+  this can be overridden by the client;
+
+- The repository path is always quoted with single quotes.
+
+Fetching Data From a Server
+===========================
+
+When one Git repository wants to get data that a second repository
+has, the first can 'fetch' from the second.  This operation determines
+what data the server has that the client does not then streams that
+data down to the client in packfile format.
+
+
+Reference Discovery
+-------------------
+
+When the client initially connects the server will immediately respond
+with a listing of each reference it has (all branches and tags) along
+with the object name that each reference currently points to.
+
+   $ echo -e -n "0039git-upload-pack /schacon/gitbook.git\0host=example.com\0" |
+      nc -v example.com 9418
+   00887217a7c7e582c46cec22a130adf4b9d7d950fba0 HEAD\0multi_ack thin-pack side-band side-band-64k ofs-delta shallow no-progress include-tag
+   00441d3fcd5ced445d1abc402225c0b8a1299641f497 refs/heads/integration
+   003f7217a7c7e582c46cec22a130adf4b9d7d950fba0 refs/heads/master

+   003fe92df48743b7bc7d26bcaabfddde0a1e20cae47c refs/tags/v1.0^{}
+   0000
+
+Server SHOULD terminate each non-flush line using LF ("\n") terminator;
+client MUST NOT complain if there is no terminator.
+
+The returned response is a pkt-line stream describing each ref and
+its current value.  The stream MUST be sorted by name according to
+the C locale ordering.
+
+If HEAD is a valid ref, HEAD MUST appear as the first advertised
+ref.  If HEAD is not a valid ref, HEAD MUST NOT appear in the
+advertisement list at all, but other refs may still appear.
+
+The stream MUST include capability declarations behind a NUL on the
+first ref. The peeled value of a ref (that is "ref^{}") MUST be
+immediately after the ref itself, if presented. A conforming server
+MUST peel the ref if it's an annotated tag.
+
+----
+  advertised-refs  =  (no-refs / list-of-refs)
+                     flush-pkt
+
+  no-refs          =  PKT-LINE(zero-id SP "capabilities^{}"
+                     NUL capability-list LF)
+
+  list-of-refs     =  first-ref *other-ref
+  first-ref        =  PKT-LINE(obj-id SP refname
+                     NUL capability-list LF)
+
+  other-ref        =  PKT-LINE(other-tip / other-peeled)
+  other-tip        =  obj-id SP refname LF
+  other-peeled     =  obj-id SP refname "^{}" LF
+
+  capability-list  =  capability *(SP capability)
+  capability       =  1*(LC_ALPHA / DIGIT / "-" / "_")
+  LC_ALPHA         =  %x61-7A
+----
+
+Server and client MUST use lowercase for obj-id, both MUST treat obj-id
+as case-insensitive.
+
+See protocol-capabilities.txt for a list of allowed server capabilities
+and descriptions.
+
+Packfile Negotiation
+--------------------
+After reference and capabilities discovery, the client can decide
+to terminate the connection by sending a flush-pkt, telling the
+server it can now gracefully terminate (as happens with the ls-remote
+command) or it can enter the negotiation phase, where the client and
+server determine what the minimal packfile necessary for transport is.
+
+Once the client has the initial list of references that the server
+has, as well as the list of capabilities, it will begin telling the
+server what objects it wants and what objects it has, so the server
+can make a packfile that only contains the objects that the client needs.
+The client will also send a list of the capabilities it wants to be in
+effect, out of what the server said it could do with the first 'want' line.
+
+----
+  upload-request    =  want-list
+                      have-list
+                      compute-end
+
+  want-list         =  first-want
+                      *additional-want
+                      flush-pkt
+
+  first-want        =  PKT-LINE("want" SP obj-id SP capability-list LF)
+  additional-want   =  PKT-LINE("want" SP obj-id LF)
+
+  have-list         =  *have-line
+  have-line         =  PKT-LINE("have" SP obj-id LF)
+  compute-end       =  flush-pkt / PKT-LINE("done")
+----
+
+Clients MUST send all the obj-ids it wants from the reference
+discovery phase as 'want' lines. Clients MUST send at least one
+'want' command in the request body. Clients MUST NOT mention an
+obj-id in a 'want' command which did not appear in the response
+obtained through ref discovery.
+
+If client is requesting a shallow clone, it will now send a 'deepen'
+line with the depth it is requesting.
+
+Once all the "want"s (and optional 'deepen') are transferred,
+clients MUST send a flush-pkt. If the client has all the references
+on the server, client flushes and disconnects.
+
+TODO: shallow/unshallow response and document the deepen command in the ABNF.
+
+Now the client will send a list of the obj-ids it has using 'have'
+lines.  In multi_ack mode, the canonical implementation will send up
+to 32 of these at a time, then will send a flush-pkt.  The canonical
+implementation will skip ahead and send the next 32 immediately,
+so that there is always a block of 32 "in-flight on the wire" at a
+time.
+
+If the server reads 'have' lines, it then will respond by ACKing any
+of the obj-ids the client said it had that the server also has. The
+server will ACK obj-ids differently depending on which ack mode is
+chosen by the client.
+
+In multi_ack mode:
+
+  * the server will respond with 'ACK obj-id continue' for any common
+    commits.
+
+  * once the server has found an acceptable common base commit and is
+    ready to make a packfile, it will blindly ACK all 'have' obj-ids
+    back to the client.
+
+  * the server will then send a 'NACK' and then wait for another response
+    from the client - either a 'done' or another list of 'have' lines.
+
+In multi_ack_detailed mode:
+
+  * the server will differentiate the ACKs where it is signaling
+    that it is ready to send data with 'ACK obj-id ready' lines, and
+    signals the identified common commits with 'ACK obj-id common' lines.
+
+Without either multi_ack or multi_ack_detailed:
+
+ * upload-pack sends "ACK obj-id" on the first common object it finds.
+   After that it says nothing until the client gives it a "done".
+
+ * upload-pack sends "NAK" on a flush-pkt if no common object
+   has been found yet.  If one has been found, and thus an ACK
+   was already sent, it's silent on the flush-pkt.
+
+After the client has gotten enough ACK responses that it can determine
+that the server has enough information to send an efficient packfile
+(in the canonical implementation, this is determined when it has received
+enough ACKs that it can color everything left in the --date-order queue
+as common with the server, or the --date-order queue is empty), or the
+client determines that it wants to give up (in the canonical implementation,
+this is determined when the client sends 256 'have' lines without getting
+any of them ACKed by the server - meaning there is nothing in common and
+the server should just send all of its objects), then the client will send
+a 'done' command.  The 'done' command signals to the server that the client
+is ready to receive its packfile data.
+
+However, the 256 limit *only* turns on in the canonical client
+implementation if we have received at least one "ACK %s continue"
+during a prior round.  This helps to ensure that at least one common
+ancestor is found before we give up entirely.
+
+Once the 'done' line is read from the client, the server will either
+send a final 'ACK obj-id' or it will send a 'NAK'. The server only sends
+ACK after 'done' if there is at least one common base and multi_ack or
+multi_ack_detailed is enabled. The server always sends NAK after 'done'
+if there is no common base found.
+
+Then the server will start sending its packfile data.
+
+----
+  server-response = *ack_multi ack / nak
+  ack_multi       = PKT-LINE("ACK" SP obj-id ack_status LF)
+  ack_status      = "continue" / "common" / "ready"
+  ack             = PKT-LINE("ACK SP obj-id LF)
+  nak             = PKT-LINE("NAK" LF)

+
+   S: 003aACK 74730d410fcb6603ace96f1dc55ea6196122532d\n
+   S: [PACKFILE]
+----
+
+
+Packfile Data
+-------------
+
+Now that the client and server have finished negotiation about what
+the minimal amount of data that needs to be sent to the client is, the server
+will construct and send the required data in packfile format.
+
+See pack-format.txt for what the packfile itself actually looks like.
+
+If 'side-band' or 'side-band-64k' capabilities have been specified by
+the client, the server will send the packfile data multiplexed.
+
+Each packet starting with the packet-line length of the amount of data
+that follows, followed by a single byte specifying the sideband the
+following data is coming in on.
+
+In 'side-band' mode, it will send up to 999 data bytes plus 1 control
+code, for a total of up to 1000 bytes in a pkt-line.  In 'side-band-64k'
+mode it will send up to 65519 data bytes plus 1 control code, for a
+total of up to 65520 bytes in a pkt-line.
+
+The sideband byte will be a '1', '2' or a '3'. Sideband '1' will contain
+packfile data, sideband '2' will be used for progress information that the
+client will generally print to stderr and sideband '3' is used for error
+information.
+
+If no 'side-band' capability was specified, the server will stream the
+entire packfile without multiplexing.
+
+
+Pushing Data To a Server
+========================
+
+Pushing data to a server will invoke the 'receive-pack' process on the
+server, which will allow the client to tell it which references it should
+update and then send all the data the server will need for those new
+references to be complete.  Once all the data is received and validated,
+the server will then update its references to what the client specified.
+
+Authentication
+--------------
+
+The protocol itself contains no authentication mechanisms.  That is to be
+handled by the transport, such as SSH, before the 'receive-pack' process is
+invoked.  If 'receive-pack' is configured over the Git transport, those
+repositories will be writable by anyone who can access that port (9418) as
+that transport is unauthenticated.
+
+Reference Discovery
+-------------------
+
+The reference discovery phase is done nearly the same way as it is in the
+fetching protocol. Each reference obj-id and name on the server is sent
+in packet-line format to the client, followed by a flush-pkt.  The only
+real difference is that the capability listing is different - the only
+possible values are 'report-status', 'delete-refs' and 'ofs-delta'.
+
+Reference Update Request and Packfile Transfer
+----------------------------------------------
+
+Once the client knows what references the server is at, it can send a
+list of reference update requests.  For each reference on the server
+that it wants to update, it sends a line listing the obj-id currently on
+the server, the obj-id the client would like to update it to and the name
+of the reference.
+
+This list is followed by a flush-pkt and then the packfile that should
+contain all the objects that the server will need to complete the new
+references.
+
+----
+  update-request    =  command-list [pack-file]
+
+  command-list      =  PKT-LINE(command NUL capability-list LF)
+                      *PKT-LINE(command LF)
+                      flush-pkt
+
+  command           =  create / delete / update
+  create            =  zero-id SP new-id  SP name
+  delete            =  old-id  SP zero-id SP name
+  update            =  old-id  SP new-id  SP name
+
+  old-id            =  obj-id
+  new-id            =  obj-id
+
+  pack-file         = "PACK" 28*(OCTET)
+----
+
+If the receiving end does not support delete-refs, the sending end MUST
+NOT ask for delete command.
+
+The pack-file MUST NOT be sent if the only command used is 'delete'.
+
+A pack-file MUST be sent if either create or update command is used,
+even if the server already has all the necessary objects.  In this
+case the client MUST send an empty pack-file.   The only time this
+is likely to happen is if the client is creating
+a new branch or a tag that points to an existing obj-id.
+
+The server will receive the packfile, unpack it, then validate each
+reference that is being updated that it hasn't changed while the request
+was being processed (the obj-id is still the same as the old-id), and
+it will run any update hooks to make sure that the update is acceptable.
+If all of that is fine, the server will then update the references.
+
+Report Status
+-------------
+
+After receiving the pack data from the sender, the receiver sends a
+report if 'report-status' capability is in effect.
+It is a short listing of what happened in that update.  It will first
+list the status of the packfile unpacking as either 'unpack ok' or
+'unpack [error]'.  Then it will list the status for each of the references
+that it tried to update.  Each line is either 'ok [refname]' if the
+update was successful, or 'ng [refname] [error]' if the update was not.
+
+----
+  report-status     = unpack-status
+                     1*(command-status)
+                     flush-pkt
+
+  unpack-status     = PKT-LINE("unpack" SP unpack-result LF)
+  unpack-result     = "ok" / error-msg
+
+  command-status    = command-ok / command-fail
+  command-ok        = PKT-LINE("ok" SP refname LF)
+  command-fail      = PKT-LINE("ng" SP refname SP error-msg LF)
+
+  error-msg         = 1*(OCTECT) ; where not "ok"
+----
+

+Git Protocol Capabilities
+=========================
+
+Servers SHOULD support all capabilities defined in this document.
+
+On the very first line of the initial server response of either
+receive-pack and upload-pack the first reference is followed by
+a NUL byte and then a list of space delimited server capabilities.
+These allow the server to declare what it can and cannot support
+to the client.
+
+Client will then send a space separated list of capabilities it wants
+to be in effect. The client MUST NOT ask for capabilities the server
+did not say it supports.
+
+Server MUST diagnose and abort if capabilities it does not understand
+was sent.  Server MUST NOT ignore capabilities that client requested
+and server advertised.  As a consequence of these rules, server MUST
+NOT advertise capabilities it does not understand.
+
+The 'report-status' and 'delete-refs' capabilities are sent and
+recognized by the receive-pack (push to server) process.
+
+The 'ofs-delta' capability is sent and recognized by both upload-pack
+and receive-pack protocols.
+
+All other capabilities are only recognized by the upload-pack (fetch
+from server) process.
+
+multi_ack
+---------
+
+The 'multi_ack' capability allows the server to return "ACK obj-id
+continue" as soon as it finds a commit that it can use as a common
+base, between the client's wants and the client's have set.
+
+By sending this early, the server can potentially head off the client
+from walking any further down that particular branch of the client's
+repository history.  The client may still need to walk down other
+branches, sending have lines for those, until the server has a
+complete cut across the DAG, or the client has said "done".
+
+Without multi_ack, a client sends have lines in --date-order until
+the server has found a common base.  That means the client will send
+have lines that are already known by the server to be common, because
+they overlap in time with another branch that the server hasn't found
+a common base on yet.
+
+For example suppose the client has commits in caps that the server
+doesn't and the server has commits in lower case that the client
+doesn't, as in the following diagram:
+
+       +---- u ---------------------- x
+      /              +----- y
+     /              /
+    a -- b -- c -- d -- E -- F
+       \
+       +--- Q -- R -- S
+
+If the client wants x,y and starts out by saying have F,S, the server
+doesn't know what F,S is.  Eventually the client says "have d" and
+the server sends "ACK d continue" to let the client know to stop
+walking down that line (so don't send c-b-a), but it's not done yet,
+it needs a base for x. The client keeps going with S-R-Q, until a
+gets reached, at which point the server has a clear base and it all
+ends.
+
+Without multi_ack the client would have sent that c-b-a chain anyway,
+interleaved with S-R-Q.
+
+thin-pack
+---------
+
+This capability means that the server can send a 'thin' pack, a pack
+which does not contain base objects; if those base objects are available
+on client side. Client requests 'thin-pack' capability when it
+understands how to "thicken" it by adding required delta bases making
+it self-contained.
+
+Client MUST NOT request 'thin-pack' capability if it cannot turn a thin
+pack into a self-contained pack.
+
+
+side-band, side-band-64k
+------------------------
+
+This capability means that server can send, and client understand multiplexed
+progress reports and error info interleaved with the packfile itself.
+
+These two options are mutually exclusive. A modern client always
+favors 'side-band-64k'.
+
+Either mode indicates that the packfile data will be streamed broken
+up into packets of up to either 1000 bytes in the case of 'side_band',
+or 65520 bytes in the case of 'side_band_64k'. Each packet is made up
+of a leading 4-byte pkt-line length of how much data is in the packet,
+followed by a 1-byte stream code, followed by the actual data.
+
+The stream code can be one of:
+
+ 1 - pack data
+ 2 - progress messages
+ 3 - fatal error message just before stream aborts
+
+The "side-band-64k" capability came about as a way for newer clients
+that can handle much larger packets to request packets that are
+actually crammed nearly full, while maintaining backward compatibility
+for the older clients.
+
+Further, with side-band and its up to 1000-byte messages, it's actually
+999 bytes of payload and 1 byte for the stream code. With side-band-64k,
+same deal, you have up to 65519 bytes of data and 1 byte for the stream
+code.
+
+The client MUST send only maximum of one of "side-band" and "side-
+band-64k".  Server MUST diagnose it as an error if client requests
+both.
+
+ofs-delta
+---------
+
+Server can send, and client understand PACKv2 with delta refering to
+its base by position in pack rather than by an obj-id.  That is, they can
+send/read OBJ_OFS_DELTA (aka type 6) in a packfile.
+
+shallow
+-------
+
+This capability adds "deepen", "shallow" and "unshallow" commands to
+the  fetch-pack/upload-pack protocol so clients can request shallow
+clones.
+
+no-progress
+-----------
+
+The client was started with "git clone -q" or something, and doesn't
+want that side band 2.  Basically the client just says "I do not
+wish to receive stream 2 on sideband, so do not send it to me, and if
+you did, I will drop it on the floor anyway".  However, the sideband
+channel 3 is still used for error responses.
+
+include-tag
+-----------
+
+The 'include-tag' capability is about sending annotated tags if we are
+sending objects they point to.  If we pack an object to the client, and
+a tag object points exactly at that object, we pack the tag object too.
+In general this allows a client to get all new annotated tags when it
+fetches a branch, in a single network connection.
+
+Clients MAY always send include-tag, hardcoding it into a request when
+the server advertises this capability. The decision for a client to
+request include-tag only has to do with the client's desires for tag
+data, whether or not a server had advertised objects in the
+refs/tags/* namespace.
+
+Servers MUST pack the tags if their referrant is packed and the client
+has requested include-tags.
+
+Clients MUST be prepared for the case where a server has ignored
+include-tag and has not actually sent tags in the pack.  In such
+cases the client SHOULD issue a subsequent fetch to acquire the tags
+that include-tag would have otherwise given the client.
+
+The server SHOULD send include-tag, if it supports it, regardless
+of whether or not there are tags available.
+
+report-status
+-------------
+
+The upload-pack process can receive a 'report-status' capability,
+which tells it that the client wants a report of what happened after
+a packfile upload and reference update.  If the pushing client requests
+this capability, after unpacking and updating references the server
+will respond with whether the packfile unpacked successfully and if
+each reference was updated successfully.  If any of those were not
+successful, it will send back an error message.  See pack-protocol.txt
+for example messages.
+
+delete-refs
+-----------
+
+If the server sends back the 'delete-refs' capability, it means that
+it is capable of accepting a zero-id value as the target
+value of a reference update.  It is not sent back by the client, it
+simply informs the client that it can be sent zero-id values
+to delete references.

+Documentation Common to Pack and Http Protocols
+===============================================
+
+ABNF Notation
+-------------
+
+ABNF notation as described by RFC 5234 is used within the protocol documents,
+except the following replacement core rules are used:
+----
+  HEXDIG    =  DIGIT / "a" / "b" / "c" / "d" / "e" / "f"
+----
+
+We also define the following common rules:
+----
+  NUL       =  %x00
+  zero-id   =  40*"0"
+  obj-id    =  40*(HEXDIGIT)
+
+  refname  =  "HEAD"
+  refname /=  "refs/" <see discussion below>
+----
+
+A refname is a hierarchical octet string beginning with "refs/" and
+not violating the 'git-check-ref-format' command's validation rules.
+More specifically, they:
+
+. They can include slash `/` for hierarchical (directory)
+  grouping, but no slash-separated component can begin with a
+  dot `.`.
+
+. They must contain at least one `/`. This enforces the presence of a
+  category like `heads/`, `tags/` etc. but the actual names are not
+  restricted.
+
+. They cannot have two consecutive dots `..` anywhere.
+
+. They cannot have ASCII control characters (i.e. bytes whose
+  values are lower than \040, or \177 `DEL`), space, tilde `~`,
+  caret `{caret}`, colon `:`, question-mark `?`, asterisk `*`,
+  or open bracket `[` anywhere.
+
+. They cannot end with a slash `/` nor a dot `.`.
+
+. They cannot end with the sequence `.lock`.
+
+. They cannot contain a sequence `@{`.
+
+. They cannot contain a `\\`.
+
+
+pkt-line Format
+---------------
+
+Much (but not all) of the payload is described around pkt-lines.
+
+A pkt-line is a variable length binary string.  The first four bytes
+of the line, the pkt-len, indicates the total length of the line,
+in hexadecimal.  The pkt-len includes the 4 bytes used to contain
+the length's hexadecimal representation.
+
+A pkt-line MAY contain binary data, so implementors MUST ensure
+pkt-line parsing/formatting routines are 8-bit clean.
+
+A non-binary line SHOULD BE terminated by an LF, which if present
+MUST be included in the total length.
+
+The maximum length of a pkt-line's data component is 65520 bytes.
+Implementations MUST NOT send pkt-line whose length exceeds 65524
+(65520 bytes of payload + 4 bytes of length data).
+
+Implementations SHOULD NOT send an empty pkt-line ("0004").
+
+A pkt-line with a length field of 0 ("0000"), called a flush-pkt,
+is a special case and MUST be handled differently than an empty
+pkt-line ("0004").
+
+----
+  pkt-line     =  data-pkt / flush-pkt
+
+  data-pkt     =  pkt-len pkt-payload
+  pkt-len      =  4*(HEXDIG)
+  pkt-payload  =  (pkt-len - 4)*(OCTET)
+
+  flush-pkt    = "0000"
+----
+
+Examples (as C-style strings):
+
+----
+  pkt-line          actual value
+  ---------------------------------
+  "0006a\n"         "a\n"
+  "0005a"           "a"
+  "000bfoobar\n"    "foobar\n"
+  "0004"            ""

+nedalloc v1.05 15th June 2008:
+-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
+
+by Niall Douglas (http://www.nedprod.com/programs/portable/nedmalloc/)
+
+Enclosed is nedalloc, an alternative malloc implementation for multiple
+threads without lock contention based on dlmalloc v2.8.4. It is more
+or less a newer implementation of ptmalloc2, the standard allocator in
+Linux (which is based on dlmalloc v2.7.0) but also contains a per-thread
+cache for maximum CPU scalability.
+
+It is licensed under the Boost Software License which basically means
+you can do anything you like with it. This does not apply to the malloc.c.h
+file which remains copyright to others.
+
+It has been tested on win32 (x86), win64 (x64), Linux (x64), FreeBSD (x64)
+and Apple MacOS X (x86). It works very well on all of these and is very
+significantly faster than the system allocator on all of these platforms.
+
+By literally dropping in this allocator as a replacement for your system
+allocator, you can see real world improvements of up to three times in normal
+code!
+
+To use:
+-=-=-=-
+Drop in nedmalloc.h, nedmalloc.c and malloc.c.h into your project.
+Configure using the instructions in nedmalloc.h. Run and enjoy.
+
+To test, compile test.c. It will run a comparison between your system
+allocator and nedalloc and tell you how much faster nedalloc is. It also
+serves as an example of usage.
+
+Notes:
+-=-=-=
+If you want the very latest version of this allocator, get it from the
+TnFOX SVN repository at svn://svn.berlios.de/viewcvs/tnfox/trunk/src/nedmalloc
+
+Because of how nedalloc allocates an mspace per thread, it can cause
+severe bloating of memory usage under certain allocation patterns.
+You can substantially reduce this wastage by setting MAXTHREADSINPOOL
+or the threads parameter to nedcreatepool() to a fraction of the number of
+threads which would normally be in a pool at once. This will reduce
+bloating at the cost of an increase in lock contention. If allocated size
+is less than THREADCACHEMAX, locking is avoided 90-99% of the time and
+if most of your allocations are below this value, you can safely set
+MAXTHREADSINPOOL to one.
+
+You will suffer memory leakage unless you call neddisablethreadcache()
+per pool for every thread which exits. This is because nedalloc cannot
+portably know when a thread exits and thus when its thread cache can
+be returned for use by other code. Don't forget pool zero, the system pool.
+
+For C++ type allocation patterns (where the same sizes of memory are
+regularly allocated and deallocated as objects are created and destroyed),
+the threadcache always benefits performance. If however your allocation
+patterns are different, searching the threadcache may significantly slow
+down your code - as a rule of thumb, if cache utilisation is below 80%
+(see the source for neddisablethreadcache() for how to enable debug
+printing in release mode) then you should disable the thread cache for
+that thread. You can compile out the threadcache code by setting
+THREADCACHEMAX to zero.
+
+Speed comparisons:
+-=-=-=-=-=-=-=-=-=
+See Benchmarks.xls for details.
+
+The enclosed test.c can do two things: it can be a torture test or a speed
+test. The speed test is designed to be a representative synthetic
+memory allocator test. It works by randomly mixing allocations with frees
+with half of the allocation sizes being a two power multiple less than
+512 bytes (to mimic C++ stack instantiated objects) and the other half
+being a simple random value less than 16Kb.
+
+The real world code results are from Tn's TestIO benchmark. This is a
+heavily multithreaded and memory intensive benchmark with a lot of branching
+and other stuff modern processors don't like so much. As you'll note, the
+test doesn't show the benefits of the threadcache mostly due to the saturation
+of the memory bus being the limiting factor.
+
+ChangeLog:
+-=-=-=-=-=
+v1.05 15th June 2008:
+ * { 1042 } Added error check for TLSSET() and TLSFREE() macros. Thanks to
+Markus Elfring for reporting this.
+ * { 1043 } Fixed a segfault when freeing memory allocated using
+nedindependent_comalloc(). Thanks to Pavel Vozenilek for reporting this.
+
+v1.04 14th July 2007:
+ * Fixed a bug with the new optimised implementation that failed to lock
+on a realloc under certain conditions.
+ * Fixed lack of thread synchronisation in InitPool() causing pool corruption
+ * Fixed a memory leak of thread cache contents on disabling. Thanks to Earl
+Chew for reporting this.
+ * Added a sanity check for freed blocks being valid.
+ * Reworked test.c into being a torture test.
+ * Fixed GCC assembler optimisation misspecification
+
+v1.04alpha_svn915 7th October 2006:
+ * Fixed failure to unlock thread cache list if allocating a new list failed.
+Thanks to Dmitry Chichkov for reporting this. Futher thanks to Aleksey Sanin.
+ * Fixed realloc(0, <size>) segfaulting. Thanks to Dmitry Chichkov for
+reporting this.
+ * Made config defines #ifndef so they can be overriden by the build system.
+Thanks to Aleksey Sanin for suggesting this.
+ * Fixed deadlock in nedprealloc() due to unnecessary locking of preferred
+thread mspace when mspace_realloc() always uses the original block's mspace
+anyway. Thanks to Aleksey Sanin for reporting this.
+ * Made some speed improvements by hacking mspace_malloc() to no longer lock
+its mspace, thus allowing the recursive mutex implementation to be removed
+with an associated speed increase. Thanks to Aleksey Sanin for suggesting this.
+ * Fixed a bug where allocating mspaces overran its max limit. Thanks to
+Aleksey Sanin for reporting this.
+
+v1.03 10th July 2006:
+ * Fixed memory corruption bug in threadcache code which only appeared with >4
+threads and in heavy use of the threadcache.
+
+v1.02 15th May 2006:
+ * Integrated dlmalloc v2.8.4, fixing the win32 memory release problem and
+improving performance still further. Speed is now up to twice the speed of v1.01
+(average is 67% faster).
+ * Fixed win32 critical section implementation. Thanks to Pavel Kuznetsov
+for reporting this.
+ * Wasn't locking mspace if all mspaces were locked. Thanks to Pavel Kuznetsov
+for reporting this.
+ * Added Apple Mac OS X support.
+
+v1.01 24th February 2006:
+ * Fixed multiprocessor scaling problems by removing sources of cache sloshing
+ * Earl Chew <earl_chew <at> agilent <dot> com> sent patches for the following:
+   1. size2binidx() wasn't working for default code path (non x86)
+   2. Fixed failure to release mspace lock under certain circumstances which
+      caused a deadlock
+
+v1.00 1st January 2006:
+ * First release

+   Note: There may be an updated version of this malloc obtainable at
+          ftp://gee.cs.oswego.edu/pub/misc/malloc.c
+        Check before installing!
+
+* Quickstart
+
+  This library is all in one file to simplify the most common usage:
+  ftp it, compile it (-O3), and link it into another program. All of
+  the compile-time options default to reasonable values for use on
+  most platforms.  You might later want to step through various
+  compile-time and dynamic tuning options.
+
+  For convenience, an include file for code using this malloc is at:
+     ftp://gee.cs.oswego.edu/pub/misc/malloc-2.8.4.h
+  You don't really need this .h file unless you call functions not
+  defined in your system include files.  The .h file contains only the
+  excerpts from this file needed for using this malloc on ANSI C/C++
+  systems, so long as you haven't changed compile-time options about
+  naming and tuning parameters.  If you do, then you can create your
+  own malloc.h that does include all settings by cutting at the point
+  indicated below. Note that you may already by default be using a C
+  library containing a malloc that is based on some version of this
+  malloc (for example in linux). You might still want to use the one
+  in this file to customize settings or to avoid overheads associated
+  with library versions.
+
+* Vital statistics:
+
+  Supported pointer/size_t representation:       4 or 8 bytes
+       size_t MUST be an unsigned type of the same width as
+       pointers. (If you are using an ancient system that declares
+       size_t as a signed type, or need it to be a different width
+       than pointers, you can use a previous release of this malloc
+       (e.g. 2.7.2) supporting these.)
+
+  Alignment:                                     8 bytes (default)
+       This suffices for nearly all current machines and C compilers.
+       However, you can define MALLOC_ALIGNMENT to be wider than this
+       if necessary (up to 128bytes), at the expense of using more space.
+
+  Minimum overhead per allocated chunk:   4 or  8 bytes (if 4byte sizes)
+                                         8 or 16 bytes (if 8byte sizes)
+       Each malloced chunk has a hidden word of overhead holding size
+       and status information, and additional cross-check word
+       if FOOTERS is defined.
+
+  Minimum allocated size: 4-byte ptrs:  16 bytes    (including overhead)
+                         8-byte ptrs:  32 bytes    (including overhead)
+
+       Even a request for zero bytes (i.e., malloc(0)) returns a
+       pointer to something of the minimum allocatable size.
+       The maximum overhead wastage (i.e., number of extra bytes
+       allocated than were requested in malloc) is less than or equal
+       to the minimum size, except for requests >= mmap_threshold that
+       are serviced via mmap(), where the worst case wastage is about
+       32 bytes plus the remainder from a system page (the minimal
+       mmap unit); typically 4096 or 8192 bytes.
+
+  Security: static-safe; optionally more or less
+       The "security" of malloc refers to the ability of malicious
+       code to accentuate the effects of errors (for example, freeing
+       space that is not currently malloc'ed or overwriting past the
+       ends of chunks) in code that calls malloc.  This malloc
+       guarantees not to modify any memory locations below the base of
+       heap, i.e., static variables, even in the presence of usage
+       errors.  The routines additionally detect most improper frees
+       and reallocs.  All this holds as long as the static bookkeeping
+       for malloc itself is not corrupted by some other means.  This
+       is only one aspect of security -- these checks do not, and
+       cannot, detect all possible programming errors.
+
+       If FOOTERS is defined nonzero, then each allocated chunk
+       carries an additional check word to verify that it was malloced
+       from its space.  These check words are the same within each
+       execution of a program using malloc, but differ across
+       executions, so externally crafted fake chunks cannot be
+       freed. This improves security by rejecting frees/reallocs that
+       could corrupt heap memory, in addition to the checks preventing
+       writes to statics that are always on.  This may further improve
+       security at the expense of time and space overhead.  (Note that
+       FOOTERS may also be worth using with MSPACES.)
+
+       By default detected errors cause the program to abort (calling
+       "abort()"). You can override this to instead proceed past
+       errors by defining PROCEED_ON_ERROR.  In this case, a bad free
+       has no effect, and a malloc that encounters a bad address
+       caused by user overwrites will ignore the bad address by
+       dropping pointers and indices to all known memory. This may
+       be appropriate for programs that should continue if at all
+       possible in the face of programming errors, although they may
+       run out of memory because dropped memory is never reclaimed.
+
+       If you don't like either of these options, you can define
+       CORRUPTION_ERROR_ACTION and USAGE_ERROR_ACTION to do anything
+       else. And if if you are sure that your program using malloc has
+       no errors or vulnerabilities, you can define INSECURE to 1,
+       which might (or might not) provide a small performance improvement.
+
+  Thread-safety: NOT thread-safe unless USE_LOCKS defined
+       When USE_LOCKS is defined, each public call to malloc, free,
+       etc is surrounded with either a pthread mutex or a win32
+       spinlock (depending on WIN32). This is not especially fast, and
+       can be a major bottleneck.  It is designed only to provide
+       minimal protection in concurrent environments, and to provide a
+       basis for extensions.  If you are using malloc in a concurrent
+       program, consider instead using nedmalloc
+       (http://www.nedprod.com/programs/portable/nedmalloc/) or
+       ptmalloc (See http://www.malloc.de), which are derived
+       from versions of this malloc.
+
+  System requirements: Any combination of MORECORE and/or MMAP/MUNMAP
+       This malloc can use unix sbrk or any emulation (invoked using
+       the CALL_MORECORE macro) and/or mmap/munmap or any emulation
+       (invoked using CALL_MMAP/CALL_MUNMAP) to get and release system
+       memory.  On most unix systems, it tends to work best if both
+       MORECORE and MMAP are enabled.  On Win32, it uses emulations
+       based on VirtualAlloc. It also uses common C library functions
+       like memset.
+
+  Compliance: I believe it is compliant with the Single Unix Specification
+       (See http://www.unix.org). Also SVID/XPG, ANSI C, and probably
+       others as well.
+
+* Overview of algorithms
+
+  This is not the fastest, most space-conserving, most portable, or
+  most tunable malloc ever written. However it is among the fastest
+  while also being among the most space-conserving, portable and
+  tunable.  Consistent balance across these factors results in a good
+  general-purpose allocator for malloc-intensive programs.
+
+  In most ways, this malloc is a best-fit allocator. Generally, it
+  chooses the best-fitting existing chunk for a request, with ties
+  broken in approximately least-recently-used order. (This strategy
+  normally maintains low fragmentation.) However, for requests less
+  than 256bytes, it deviates from best-fit when there is not an
+  exactly fitting available chunk by preferring to use space adjacent
+  to that used for the previous small request, as well as by breaking
+  ties in approximately most-recently-used order. (These enhance
+  locality of series of small allocations.)  And for very large requests
+  (>= 256Kb by default), it relies on system memory mapping
+  facilities, if supported.  (This helps avoid carrying around and
+  possibly fragmenting memory used only for large chunks.)
+
+  All operations (except malloc_stats and mallinfo) have execution
+  times that are bounded by a constant factor of the number of bits in
+  a size_t, not counting any clearing in calloc or copying in realloc,
+  or actions surrounding MORECORE and MMAP that have times
+  proportional to the number of non-contiguous regions returned by
+  system allocation routines, which is often just 1. In real-time
+  applications, you can optionally suppress segment traversals using
+  NO_SEGMENT_TRAVERSAL, which assures bounded execution even when
+  system allocators return non-contiguous spaces, at the typical
+  expense of carrying around more memory and increased fragmentation.
+
+  The implementation is not very modular and seriously overuses
+  macros. Perhaps someday all C compilers will do as good a job
+  inlining modular code as can now be done by brute-force expansion,
+  but now, enough of them seem not to.
+
+  Some compilers issue a lot of warnings about code that is
+  dead/unreachable only on some platforms, and also about intentional
+  uses of negation on unsigned types. All known cases of each can be
+  ignored.
+
+  For a longer but out of date high-level description, see
+     http://gee.cs.oswego.edu/dl/html/malloc.html
+
+* MSPACES
+  If MSPACES is defined, then in addition to malloc, free, etc.,
+  this file also defines mspace_malloc, mspace_free, etc. These
+  are versions of malloc routines that take an "mspace" argument
+  obtained using create_mspace, to control all internal bookkeeping.
+  If ONLY_MSPACES is defined, only these versions are compiled.
+  So if you would like to use this allocator for only some allocations,
+  and your system malloc for others, you can compile with
+  ONLY_MSPACES and then do something like...
+    static mspace mymspace = create_mspace(0,0); // for example
+    #define mymalloc(bytes)  mspace_malloc(mymspace, bytes)
+
+  (Note: If you only need one instance of an mspace, you can instead
+  use "USE_DL_PREFIX" to relabel the global malloc.)
+
+  You can similarly create thread-local allocators by storing
+  mspaces as thread-locals. For example:
+    static __thread mspace tlms = 0;
+    void*  tlmalloc(size_t bytes) {
+      if (tlms == 0) tlms = create_mspace(0, 0);
+      return mspace_malloc(tlms, bytes);
+    }
+    void  tlfree(void* mem) { mspace_free(tlms, mem); }
+
+  Unless FOOTERS is defined, each mspace is completely independent.
+  You cannot allocate from one and free to another (although
+  conformance is only weakly checked, so usage errors are not always
+  caught). If FOOTERS is defined, then each chunk carries around a tag
+  indicating its originating mspace, and frees are directed to their
+  originating spaces.
+
+ -------------------------  Compile-time options ---------------------------
+
+Be careful in setting #define values for numerical constants of type
+size_t. On some systems, literal values are not automatically extended
+to size_t precision unless they are explicitly casted. You can also
+use the symbolic values MAX_SIZE_T, SIZE_T_ONE, etc below.
+
+WIN32                    default: defined if _WIN32 defined
+  Defining WIN32 sets up defaults for MS environment and compilers.
+  Otherwise defaults are for unix. Beware that there seem to be some
+  cases where this malloc might not be a pure drop-in replacement for
+  Win32 malloc: Random-looking failures from Win32 GDI API's (eg;
+  SetDIBits()) may be due to bugs in some video driver implementations
+  when pixel buffers are malloc()ed, and the region spans more than
+  one VirtualAlloc()ed region. Because dlmalloc uses a small (64Kb)
+  default granularity, pixel buffers may straddle virtual allocation
+  regions more often than when using the Microsoft allocator.  You can
+  avoid this by using VirtualAlloc() and VirtualFree() for all pixel
+  buffers rather than using malloc().  If this is not possible,
+  recompile this malloc with a larger DEFAULT_GRANULARITY.
+
+MALLOC_ALIGNMENT         default: (size_t)8
+  Controls the minimum alignment for malloc'ed chunks.  It must be a
+  power of two and at least 8, even on machines for which smaller
+  alignments would suffice. It may be defined as larger than this
+  though. Note however that code and data structures are optimized for
+  the case of 8-byte alignment.
+
+MSPACES                  default: 0 (false)
+  If true, compile in support for independent allocation spaces.
+  This is only supported if HAVE_MMAP is true.
+
+ONLY_MSPACES             default: 0 (false)
+  If true, only compile in mspace versions, not regular versions.
+
+USE_LOCKS                default: 0 (false)
+  Causes each call to each public routine to be surrounded with
+  pthread or WIN32 mutex lock/unlock. (If set true, this can be
+  overridden on a per-mspace basis for mspace versions.) If set to a
+  non-zero value other than 1, locks are used, but their
+  implementation is left out, so lock functions must be supplied manually.
+
+USE_SPIN_LOCKS           default: 1 iff USE_LOCKS and on x86 using gcc or MSC
+  If true, uses custom spin locks for locking. This is currently
+  supported only for x86 platforms using gcc or recent MS compilers.
+  Otherwise, posix locks or win32 critical sections are used.
+
+FOOTERS                  default: 0
+  If true, provide extra checking and dispatching by placing
+  information in the footers of allocated chunks. This adds
+  space and time overhead.
+
+INSECURE                 default: 0
+  If true, omit checks for usage errors and heap space overwrites.
+
+USE_DL_PREFIX            default: NOT defined
+  Causes compiler to prefix all public routines with the string 'dl'.
+  This can be useful when you only want to use this malloc in one part
+  of a program, using your regular system malloc elsewhere.
+
+ABORT                    default: defined as abort()
+  Defines how to abort on failed checks.  On most systems, a failed
+  check cannot die with an "assert" or even print an informative
+  message, because the underlying print routines in turn call malloc,
+  which will fail again.  Generally, the best policy is to simply call
+  abort(). It's not very useful to do more than this because many
+  errors due to overwriting will show up as address faults (null, odd
+  addresses etc) rather than malloc-triggered checks, so will also
+  abort.  Also, most compilers know that abort() does not return, so
+  can better optimize code conditionally calling it.
+
+PROCEED_ON_ERROR           default: defined as 0 (false)
+  Controls whether detected bad addresses cause them to bypassed
+  rather than aborting. If set, detected bad arguments to free and
+  realloc are ignored. And all bookkeeping information is zeroed out
+  upon a detected overwrite of freed heap space, thus losing the
+  ability to ever return it from malloc again, but enabling the
+  application to proceed. If PROCEED_ON_ERROR is defined, the
+  static variable malloc_corruption_error_count is compiled in
+  and can be examined to see if errors have occurred. This option
+  generates slower code than the default abort policy.
+
+DEBUG                    default: NOT defined
+  The DEBUG setting is mainly intended for people trying to modify
+  this code or diagnose problems when porting to new platforms.
+  However, it may also be able to better isolate user errors than just
+  using runtime checks.  The assertions in the check routines spell
+  out in more detail the assumptions and invariants underlying the
+  algorithms.  The checking is fairly extensive, and will slow down
+  execution noticeably. Calling malloc_stats or mallinfo with DEBUG
+  set will attempt to check every non-mmapped allocated and free chunk
+  in the course of computing the summaries.
+
+ABORT_ON_ASSERT_FAILURE   default: defined as 1 (true)
+  Debugging assertion failures can be nearly impossible if your
+  version of the assert macro causes malloc to be called, which will
+  lead to a cascade of further failures, blowing the runtime stack.
+  ABORT_ON_ASSERT_FAILURE cause assertions failures to call abort(),
+  which will usually make debugging easier.
+
+MALLOC_FAILURE_ACTION     default: sets errno to ENOMEM, or no-op on win32
+  The action to take before "return 0" when malloc fails to be able to
+  return memory because there is none available.
+
+HAVE_MORECORE             default: 1 (true) unless win32 or ONLY_MSPACES
+  True if this system supports sbrk or an emulation of it.
+
+MORECORE                  default: sbrk
+  The name of the sbrk-style system routine to call to obtain more
+  memory.  See below for guidance on writing custom MORECORE
+  functions. The type of the argument to sbrk/MORECORE varies across
+  systems.  It cannot be size_t, because it supports negative
+  arguments, so it is normally the signed type of the same width as
+  size_t (sometimes declared as "intptr_t").  It doesn't much matter
+  though. Internally, we only call it with arguments less than half
+  the max value of a size_t, which should work across all reasonable
+  possibilities, although sometimes generating compiler warnings.
+
+MORECORE_CONTIGUOUS       default: 1 (true) if HAVE_MORECORE
+  If true, take advantage of fact that consecutive calls to MORECORE
+  with positive arguments always return contiguous increasing
+  addresses.  This is true of unix sbrk. It does not hurt too much to
+  set it true anyway, since malloc copes with non-contiguities.
+  Setting it false when definitely non-contiguous saves time
+  and possibly wasted space it would take to discover this though.
+
+MORECORE_CANNOT_TRIM      default: NOT defined
+  True if MORECORE cannot release space back to the system when given
+  negative arguments. This is generally necessary only if you are
+  using a hand-crafted MORECORE function that cannot handle negative
+  arguments.
+
+NO_SEGMENT_TRAVERSAL       default: 0
+  If non-zero, suppresses traversals of memory segments
+  returned by either MORECORE or CALL_MMAP. This disables
+  merging of segments that are contiguous, and selectively
+  releasing them to the OS if unused, but bounds execution times.
+
+HAVE_MMAP                 default: 1 (true)
+  True if this system supports mmap or an emulation of it.  If so, and
+  HAVE_MORECORE is not true, MMAP is used for all system
+  allocation. If set and HAVE_MORECORE is true as well, MMAP is
+  primarily used to directly allocate very large blocks. It is also
+  used as a backup strategy in cases where MORECORE fails to provide
+  space from system. Note: A single call to MUNMAP is assumed to be
+  able to unmap memory that may have be allocated using multiple calls
+  to MMAP, so long as they are adjacent.
+
+HAVE_MREMAP               default: 1 on linux, else 0
+  If true realloc() uses mremap() to re-allocate large blocks and
+  extend or shrink allocation spaces.
+
+MMAP_CLEARS               default: 1 except on WINCE.
+  True if mmap clears memory so calloc doesn't need to. This is true
+  for standard unix mmap using /dev/zero and on WIN32 except for WINCE.
+
+USE_BUILTIN_FFS            default: 0 (i.e., not used)
+  Causes malloc to use the builtin ffs() function to compute indices.
+  Some compilers may recognize and intrinsify ffs to be faster than the
+  supplied C version. Also, the case of x86 using gcc is special-cased
+  to an asm instruction, so is already as fast as it can be, and so
+  this setting has no effect. Similarly for Win32 under recent MS compilers.
+  (On most x86s, the asm version is only slightly faster than the C version.)
+
+malloc_getpagesize         default: derive from system includes, or 4096.
+  The system page size. To the extent possible, this malloc manages
+  memory from the system in page-size units.  This may be (and
+  usually is) a function rather than a constant. This is ignored
+  if WIN32, where page size is determined using getSystemInfo during
+  initialization.
+
+USE_DEV_RANDOM             default: 0 (i.e., not used)
+  Causes malloc to use /dev/random to initialize secure magic seed for
+  stamping footers. Otherwise, the current time is used.
+
+NO_MALLINFO                default: 0
+  If defined, don't compile "mallinfo". This can be a simple way
+  of dealing with mismatches between system declarations and
+  those in this file.
+
+MALLINFO_FIELD_TYPE        default: size_t
+  The type of the fields in the mallinfo struct. This was originally
+  defined as "int" in SVID etc, but is more usefully defined as
+  size_t. The value is used only if  HAVE_USR_INCLUDE_MALLOC_H is not set
+
+REALLOC_ZERO_BYTES_FREES    default: not defined
+  This should be set if a call to realloc with zero bytes should
+  be the same as a call to free. Some people think it should. Otherwise,
+  since this malloc returns a unique pointer for malloc(0), so does
+  realloc(p, 0).
+
+LACKS_UNISTD_H, LACKS_FCNTL_H, LACKS_SYS_PARAM_H, LACKS_SYS_MMAN_H
+LACKS_STRINGS_H, LACKS_STRING_H, LACKS_SYS_TYPES_H,  LACKS_ERRNO_H
+LACKS_STDLIB_H                default: NOT defined unless on WIN32
+  Define these if your system does not have these header files.
+  You might need to manually insert some of the declarations they provide.
+
+DEFAULT_GRANULARITY        default: page size if MORECORE_CONTIGUOUS,
+                               system_info.dwAllocationGranularity in WIN32,
+                               otherwise 64K.
+      Also settable using mallopt(M_GRANULARITY, x)
+  The unit for allocating and deallocating memory from the system.  On
+  most systems with contiguous MORECORE, there is no reason to
+  make this more than a page. However, systems with MMAP tend to
+  either require or encourage larger granularities.  You can increase
+  this value to prevent system allocation functions to be called so
+  often, especially if they are slow.  The value must be at least one
+  page and must be a power of two.  Setting to 0 causes initialization
+  to either page size or win32 region size.  (Note: In previous
+  versions of malloc, the equivalent of this option was called
+  "TOP_PAD")
+
+DEFAULT_TRIM_THRESHOLD    default: 2MB
+      Also settable using mallopt(M_TRIM_THRESHOLD, x)
+  The maximum amount of unused top-most memory to keep before
+  releasing via malloc_trim in free().  Automatic trimming is mainly
+  useful in long-lived programs using contiguous MORECORE.  Because
+  trimming via sbrk can be slow on some systems, and can sometimes be
+  wasteful (in cases where programs immediately afterward allocate
+  more large chunks) the value should be high enough so that your
+  overall system performance would improve by releasing this much
+  memory.  As a rough guide, you might set to a value close to the
+  average size of a process (program) running on your system.
+  Releasing this much memory would allow such a process to run in
+  memory.  Generally, it is worth tuning trim thresholds when a
+  program undergoes phases where several large chunks are allocated
+  and released in ways that can reuse each other's storage, perhaps
+  mixed with phases where there are no such chunks at all. The trim
+  value must be greater than page size to have any useful effect.  To
+  disable trimming completely, you can set to MAX_SIZE_T. Note that the trick
+  some people use of mallocing a huge space and then freeing it at
+  program startup, in an attempt to reserve system memory, doesn't
+  have the intended effect under automatic trimming, since that memory
+  will immediately be returned to the system.
+
+DEFAULT_MMAP_THRESHOLD       default: 256K
+      Also settable using mallopt(M_MMAP_THRESHOLD, x)
+  The request size threshold for using MMAP to directly service a
+  request. Requests of at least this size that cannot be allocated
+  using already-existing space will be serviced via mmap.  (If enough
+  normal freed space already exists it is used instead.)  Using mmap
+  segregates relatively large chunks of memory so that they can be
+  individually obtained and released from the host system. A request
+  serviced through mmap is never reused by any other request (at least
+  not directly; the system may just so happen to remap successive
+  requests to the same locations).  Segregating space in this way has
+  the benefits that: Mmapped space can always be individually released
+  back to the system, which helps keep the system level memory demands
+  of a long-lived program low.  Also, mapped memory doesn't become
+  `locked' between other chunks, as can happen with normally allocated
+  chunks, which means that even trimming via malloc_trim would not
+  release them.  However, it has the disadvantage that the space
+  cannot be reclaimed, consolidated, and then used to service later
+  requests, as happens with normal chunks.  The advantages of mmap
+  nearly always outweigh disadvantages for "large" chunks, but the
+  value of "large" may vary across systems.  The default is an
+  empirically derived value that works well in most systems. You can
+  disable mmap by setting to MAX_SIZE_T.
+
+MAX_RELEASE_CHECK_RATE   default: 4095 unless not HAVE_MMAP
+  The number of consolidated frees between checks to release
+  unused segments when freeing. When using non-contiguous segments,
+  especially with multiple mspaces, checking only for topmost space
+  doesn't always suffice to trigger trimming. To compensate for this,
+  free() will, with a period of MAX_RELEASE_CHECK_RATE (or the
+  current number of segments, if greater) try to release unused
+  segments to the OS when freeing chunks that result in
+  consolidation. The best value for this parameter is a compromise
+  between slowing down frees with relatively costly checks that
+  rarely trigger versus holding on to unused memory. To effectively
+  disable, set to MAX_SIZE_T. This may lead to a very slight speed
+  improvement at the expense of carrying around more memory.

+  independent_calloc is similar to calloc, but instead of returning a

+  independent elements that can hold contents of size elem_size, each
+  of which starts out cleared, and can be independently freed,
+  realloc'ed etc. The elements are guaranteed to be adjacently
+  allocated (this is not guaranteed to occur with multiple callocs or
+  mallocs), which may also improve cache locality in some
+  applications.
+
+  The "chunks" argument is optional (i.e., may be null, which is
+  probably the most typical usage). If it is null, the returned array
+  is itself dynamically allocated and should also be freed when it is
+  no longer needed. Otherwise, the chunks array must be of at least
+  n_elements in length. It is filled in with the pointers to the
+  chunks.
+
+  In either case, independent_calloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and "chunks"
+  is null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use regular calloc and assign pointers into this
+  space to represent elements.  (In this case though, you cannot
+  independently free elements.)
+
+  independent_calloc simplifies and speeds up implementations of many
+  kinds of pools.  It may also be useful when constructing large data
+  structures that initially have a fixed number of fixed-sized nodes,
+  but the number is not known at compile time, and some of the nodes
+  may later need to be freed. For example:
+
+  struct Node { int item; struct Node* next; };
+
+  struct Node* build_list() {
+    struct Node** pool;
+    int n = read_number_of_nodes_needed();

+  independent_comalloc(size_t n_elements, size_t sizes[], void* chunks[]);
+
+  independent_comalloc allocates, all at once, a set of n_elements
+  chunks with sizes indicated in the "sizes" array.    It returns
+  an array of pointers to these elements, each of which can be
+  independently freed, realloc'ed etc. The elements are guaranteed to
+  be adjacently allocated (this is not guaranteed to occur with
+  multiple callocs or mallocs), which may also improve cache locality
+  in some applications.
+
+  The "chunks" argument is optional (i.e., may be null). If it is null
+  the returned array is itself dynamically allocated and should also
+  be freed when it is no longer needed. Otherwise, the chunks array
+  must be of at least n_elements in length. It is filled in with the
+  pointers to the chunks.
+
+  In either case, independent_comalloc returns this pointer array, or
+  null if the allocation failed.  If n_elements is zero and chunks is
+  null, it returns a chunk representing an array with zero elements
+  (which should be freed if not wanted).
+
+  Each element must be individually freed when it is no longer
+  needed. If you'd like to instead be able to free all at once, you
+  should instead use a single regular malloc, and assign pointers at
+  particular offsets in the aggregate space. (In this case though, you
+  cannot independently free elements.)
+
+  independent_comallac differs from independent_calloc in that each
+  element may have a different size, and also that it does not
+  automatically clear elements.
+
+  independent_comalloc can be used to speed up allocation in cases
+  where several structs or objects must always be allocated at the
+  same time.  For example:
+
+  struct Head { ... }
+  struct Foot { ... }
+

+    struct Foot* foot = (struct Foot*)(chunks[2]);
+    // ...
+  }
+
+  In general though, independent_comalloc is worth using only for
+  larger values of n_elements. For small values, you probably won't
+  detect enough difference from series of malloc calls to bother.

+  (The following includes lightly edited explanations by Colin Plumb.)
+
+  The malloc_chunk declaration below is misleading (but accurate and
+  necessary).  It declares a "view" into memory allowing access to
+  necessary fields at known offsets from a given base.
+
+  Chunks of memory are maintained using a `boundary tag' method as
+  originally described by Knuth.  (See the paper by Paul Wilson
+  ftp://ftp.cs.utexas.edu/pub/garbage/allocsrv.ps for a survey of such
+  techniques.)  Sizes of free chunks are stored both in the front of
+  each chunk and at the end.  This makes consolidating fragmented
+  chunks into bigger chunks fast.  The head fields also hold bits
+  representing whether chunks are free or in use.
+
+  Here are some pictures to make it clearer.  They are "exploded" to
+  show that the state of a chunk can be thought of as extending from
+  the high 31 bits of the head field of its header through the
+  prev_foot and PINUSE_BIT bit of the following chunk header.
+
+  A chunk that's in use looks like:
+
+   chunk-> +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+
+          | Size of previous chunk (if P = 0)                             |

+        +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |P|

+  Note that since we always merge adjacent free chunks, the chunks
+  adjacent to a free chunk must be in use.
+
+  Given a pointer to a chunk (which can be derived trivially from the
+  payload pointer) we can, in O(1) time, find out whether the adjacent
+  chunks are free, and if so, unlink them from the lists that they
+  are on and merge them with the current chunk.
+
+  Chunks always begin on even word boundaries, so the mem portion
+  (which is returned to the user) is also on an even word boundary, and
+  thus at least double-word aligned.
+
+  The P (PINUSE_BIT) bit, stored in the unused low-order bit of the
+  chunk size (which is always a multiple of two words), is an in-use
+  bit for the *previous* chunk.  If that bit is *clear*, then the
+  word before the current chunk size contains the previous chunk
+  size, and can be used to find the front of the previous chunk.
+  The very first chunk allocated always has this bit set, preventing
+  access to non-existent (or non-owned) memory. If pinuse is set for
+  any given chunk, then you CANNOT determine the size of the
+  previous chunk, and might even get a memory addressing fault when
+  trying to do so.
+
+  The C (CINUSE_BIT) bit, stored in the unused second-lowest bit of
+  the chunk size redundantly records whether the current chunk is
+  inuse. This redundancy enables usage checks within free and realloc,
+  and reduces indirection when freeing and consolidating chunks.
+
+  Each freshly allocated chunk must have both cinuse and pinuse set.
+  That is, each allocated chunk borders either a previously allocated
+  and still in-use chunk, or the base of its memory arena. This is
+  ensured by making all allocations from the the `lowest' part of any
+  found chunk.  Further, no free chunk physically borders another one,
+  so each free chunk is known to be preceded and followed by either
+  inuse chunks or the ends of memory.
+
+  Note that the `foot' of the current chunk is actually represented
+  as the prev_foot of the NEXT chunk. This makes it easier to
+  deal with alignments etc but can be very confusing when trying
+  to extend or adapt this code.
+
+  The exceptions to all this are
+
+     1. The special chunk `top' is the top-most available chunk (i.e.,
+       the one bordering the end of available memory). It is treated
+       specially.  Top is never included in any bin, is used only if
+       no other chunk is available, and is released back to the
+       system if it is very large (see M_TRIM_THRESHOLD).  In effect,
+       the top chunk is treated as larger (and thus less well
+       fitting) than any other available chunk.  The top chunk
+       doesn't update its trailing size field since there is no next
+       contiguous chunk that would have to index off it. However,
+       space is still allocated for it (TOP_FOOT_SIZE) to enable
+       separation or merging when space is extended.
+
+     3. Chunks allocated via mmap, which have the lowest-order bit
+       (IS_MMAPPED_BIT) set in their prev_foot fields, and do not set
+       PINUSE_BIT in their head fields.  Because they are allocated
+       one-by-one, each must carry its own prev_foot field, which is
+       also used to hold the offset this chunk has within its mmapped
+       region, which is needed to preserve alignment. Each mmapped
+       chunk is trailed by the first two fields of a fake next-chunk
+       for sake of usage checks.

+
+  Each tree holding treenodes is a tree of unique chunk sizes.  Chunks
+  of the same size are arranged in a circularly-linked list, with only
+  the oldest chunk (the next to be used, in our FIFO ordering)
+  actually in the tree.  (Tree members are distinguished by a non-null
+  parent pointer.)  If a chunk with the same size an an existing node
+  is inserted, it is linked off the existing node using pointers that
+  work in the same way as fd/bk pointers of small chunks.
+
+  Each tree contains a power of 2 sized range of chunk sizes (the
+  smallest is 0x100 <= x < 0x180), which is is divided in half at each
+  tree level, with the chunks in the smaller half of the range (0x100
+  <= x < 0x140 for the top nose) in the left subtree and the larger
+  half (0x140 <= x < 0x180) in the right subtree.  This is, of course,
+  done by inspecting individual bits.
+
+  Using these rules, each node's left subtree contains all smaller
+  sizes than its right subtree.  However, the node at the root of each
+  subtree has no particular ordering relationship to either.  (The
+  dividing line between the subtree sizes is based on trie relation.)
+  If we remove the last chunk of a given size from the interior of the
+  tree, we need to replace it with a leaf node.  The tree ordering
+  rules permit a node to be replaced by any leaf below it.
+
+  The smallest chunk in a tree (a common operation in a best-fit
+  allocator) can be found by walking a path to the leftmost leaf in
+  the tree.  Unlike a usual binary tree, where we follow left child
+  pointers until we reach a null, here we follow the right child
+  pointer any time the left one is null, until we reach a leaf with
+  both child pointers null. The smallest chunk in the tree will be
+  somewhere along that path.
+
+  The worst case number of steps to add, find, or remove a node is
+  bounded by the number of bits differentiating chunks within
+  bins. Under current bin calculations, this ranges from 6 up to 21
+  (for 32 bit sizes) or up to 53 (for 64 bit sizes). The typical case
+  is of course much better.

+/* ----------------------------- Segments -------------------------------- */
+
+/*
+  Each malloc space may include non-contiguous segments, held in a
+  list headed by an embedded malloc_segment record representing the
+  top-most space. Segments also include flags holding properties of
+  the space. Large chunks that are directly allocated by mmap are not
+  included in this list. They are instead independently created and
+  destroyed without otherwise keeping track of them.
+
+  Segment management mainly comes into play for spaces allocated by
+  MMAP.  Any call to MMAP might or might not return memory that is
+  adjacent to an existing segment.  MORECORE normally contiguously
+  extends the current space, so this space is almost always adjacent,
+  which is simpler and faster to deal with. (This is why MORECORE is
+  used preferentially to MMAP when both are available -- see
+  sys_alloc.)  When allocating using MMAP, we don't use any of the
+  hinting mechanisms (inconsistently) supported in various
+  implementations of unix mmap, or distinguish reserving from
+  committing memory. Instead, we just ask for space, and exploit
+  contiguity when we get it.  It is probably possible to do
+  better than this on some systems, but no general scheme seems
+  to be significantly better.
+
+  Management entails a simpler variant of the consolidation scheme
+  used for chunks to reduce fragmentation -- new adjacent memory is
+  normally prepended or appended to an existing segment. However,
+  there are limitations compared to chunk consolidation that mostly
+  reflect the fact that segment processing is relatively infrequent
+  (occurring only when getting memory from system) and that we
+  don't expect to have huge numbers of segments:
+
+  * Segments are not indexed, so traversal requires linear scans.  (It
+    would be possible to index these, but is not worth the extra
+    overhead and complexity for most programs on most platforms.)
+  * New segments are only appended to old ones when holding top-most
+    memory; if they cannot be prepended to others, they are held in
+    different segments.
+
+  Except for the top-most segment of an mstate, each segment record
+  is kept at the tail of its segment. Segments are added by pushing
+  segment records onto the list headed by &mstate.seg for the
+  containing mstate.
+
+  Segment flags control allocation/merge/deallocation policies:
+  * If EXTERN_BIT set, then we did not allocate this segment,
+    and so should not try to deallocate or merge with others.
+    (This currently holds only for the initial segment passed
+    into create_mspace_with_base.)
+  * If IS_MMAPPED_BIT set, the segment may be merged with
+    other surrounding mmapped segments and trimmed/de-allocated
+    using munmap.
+  * If neither bit is set, then the segment was obtained using
+    MORECORE so can be merged with surrounding MORECORE'd segments
+    and deallocated/trimmed using MORECORE with negative arguments.

+
+/*
+   A malloc_state holds all of the bookkeeping for a space.
+   The main fields are:
+
+  Top
+    The topmost chunk of the currently active segment. Its size is
+    cached in topsize.  The actual size of topmost space is
+    topsize+TOP_FOOT_SIZE, which includes space reserved for adding
+    fenceposts and segment records if necessary when getting more
+    space from the system.  The size at which to autotrim top is
+    cached from mparams in trim_check, except that it is disabled if
+    an autotrim fails.
+
+  Designated victim (dv)
+    This is the preferred chunk for servicing small requests that
+    don't have exact fits.  It is normally the chunk split off most
+    recently to service another small request.  Its size is cached in
+    dvsize. The link fields of this chunk are not maintained since it
+    is not kept in a bin.
+
+  SmallBins
+    An array of bin headers for free chunks.  These bins hold chunks
+    with sizes less than MIN_LARGE_SIZE bytes. Each bin contains
+    chunks of all the same size, spaced 8 bytes apart.  To simplify
+    use in double-linked lists, each bin header acts as a malloc_chunk
+    pointing to the real first node, if it exists (else pointing to
+    itself).  This avoids special-casing for headers.  But to avoid
+    waste, we allocate only the fd/bk pointers of bins, and then use
+    repositioning tricks to treat these as the fields of a chunk.
+
+  TreeBins
+    Treebins are pointers to the roots of trees holding a range of
+    sizes. There are 2 equally spaced treebins for each power of two
+    from TREE_SHIFT to TREE_SHIFT+16. The last bin holds anything
+    larger.
+
+  Bin maps
+    There is one bit map for small bins ("smallmap") and one for
+    treebins ("treemap).  Each bin sets its bit when non-empty, and
+    clears the bit when empty.  Bit operations are then used to avoid
+    bin-by-bin searching -- nearly all "search" is done without ever
+    looking at bins that won't be selected.  The bit maps
+    conservatively use 32 bits per map word, even if on 64bit system.
+    For a good description of some of the bit-based techniques used
+    here, see Henry S. Warren Jr's book "Hacker's Delight" (and
+    supplement at http://hackersdelight.org/). Many of these are
+    intended to reduce the branchiness of paths through malloc etc, as
+    well as to reduce the number of memory locations read or written.
+
+  Segments
+    A list of segments headed by an embedded malloc_segment record
+    representing the initial space.
+
+  Address check support
+    The least_addr field is the least address ever obtained from
+    MORECORE or MMAP. Attempted frees and reallocs of any address less
+    than this are trapped (unless INSECURE is defined).
+
+  Magic tag
+    A cross-check field that should always hold same value as mparams.magic.
+
+  Flags
+    Bits recording whether to use MMAP, locks, or contiguous MORECORE
+
+  Statistics
+    Each space keeps track of current and maximum system memory
+    obtained via MORECORE or MMAP.
+
+  Trim support
+    Fields holding the amount of unused topmost memory that should trigger
+    timming, and a counter to force periodic scanning to release unused
+    non-topmost segments.
+
+  Locking
+    If USE_LOCKS is defined, the "mutex" lock is acquired and released
+    around every public call using this mspace.
+
+  Extension support
+    A void* pointer and a size_t field that can be used to help implement
+    extensions to this malloc.

+  For security, the main invariant is that malloc/free/etc never
+  writes to a static address other than malloc_state, unless static
+  malloc_state itself has been corrupted, which cannot occur via
+  malloc (because of these checks). In essence this means that we
+  believe all pointers, sizes, maps etc held in malloc_state, but
+  check all of those linked or offsetted from other embedded data
+  structures.  These checks are interspersed with main code in a way
+  that tends to minimize their run-time cost.
+
+  When FOOTERS is defined, in addition to range checking, we also
+  verify footer fields of inuse chunks, which can be used guarantee
+  that the mstate controlling malloc/free is intact.  This is a
+  streamlined version of the approach described by William Robertson
+  et al in "Run-time Detection of Heap-based Overflows" LISA'03
+  http://www.usenix.org/events/lisa03/tech/robertson.html The footer
+  of an inuse chunk holds the xor of its mstate and a random seed,
+  that is checked upon calls to free() and realloc().  This is
+  (probablistically) unguessable from outside the program, but can be
+  computed by any code successfully malloc'ing any chunk, so does not
+  itself provide protection against code that has already broken
+  security through some other means.  Unlike Robertson et al, we
+  always dynamically check addresses of all offset chunks (previous,
+  next, etc). This turns out to be cheaper than relying on hashes.

+/* -------------------- Alternative MORECORE functions ------------------- */
+
+/*
+  Guidelines for creating a custom version of MORECORE:
+
+  * For best performance, MORECORE should allocate in multiples of pagesize.
+  * MORECORE may allocate more memory than requested. (Or even less,
+      but this will usually result in a malloc failure.)
+  * MORECORE must not allocate memory when given argument zero, but
+      instead return one past the end address of memory from previous
+      nonzero call.
+  * For best performance, consecutive calls to MORECORE with positive
+      arguments should return increasing addresses, indicating that
+      space has been contiguously extended.
+  * Even though consecutive calls to MORECORE need not return contiguous
+      addresses, it must be OK for malloc'ed chunks to span multiple
+      regions in those cases where they do happen to be contiguous.
+  * MORECORE need not handle negative arguments -- it may instead
+      just return MFAIL when given negative arguments.
+      Negative arguments are always multiples of pagesize. MORECORE
+      must not misinterpret negative args as large positive unsigned
+      args. You can suppress all such calls from even occurring by defining
+      MORECORE_CANNOT_TRIM,
+
+  As an example alternative MORECORE, here is a custom allocator
+  kindly contributed for pre-OSX macOS.  It uses virtually but not
+  necessarily physically contiguous non-paged memory (locked in,
+  present and won't get swapped out).  You can use it by uncommenting
+  this section, adding some #includes, and setting up the appropriate
+  defines above:
+
+      #define MORECORE osMoreCore
+
+  There is also a shutdown routine that should somehow be called for
+  cleanup upon program exit.
+
+  #define MAX_POOL_ENTRIES 100
+  #define MINIMUM_MORECORE_SIZE  (64 * 1024U)
+  static int next_os_pool;
+  void *our_os_pools[MAX_POOL_ENTRIES];
+
+  void *osMoreCore(int size)
+  {
+    void *ptr = 0;
+    static void *sbrk_top = 0;
+
+    if (size > 0)
+    {
+      if (size < MINIMUM_MORECORE_SIZE)
+        size = MINIMUM_MORECORE_SIZE;
+      if (CurrentExecutionLevel() == kTaskLevel)
+        ptr = PoolAllocateResident(size + RM_PAGE_SIZE, 0);
+      if (ptr == 0)
+      {
+       return (void *) MFAIL;
+      }
+      // save ptrs so they can be freed during cleanup
+      our_os_pools[next_os_pool] = ptr;
+      next_os_pool++;
+      ptr = (void *) ((((size_t) ptr) + RM_PAGE_MASK) & ~RM_PAGE_MASK);
+      sbrk_top = (char *) ptr + size;
+      return ptr;

+    V2.6.1 Sat Dec  2 14:10:57 1995  Doug Lea  (dl at gee)
+      * Re-tuned and fixed to behave more nicely with V2.6.0 changes.
+      * Removed all preallocation code since under current scheme
+       the work required to undo bad preallocations exceeds
+       the work saved in good cases for most test programs.
+      * No longer use return list or unconsolidated bins since
+       no scheme using them consistently outperforms those that don't
+       given above changes.

+
+    V2.5.2 Tue Apr  5 16:20:40 1994  Doug Lea  (dl at g)
+      * realloc: try to expand in both directions
+      * malloc: swap order of clean-bin strategy;
+      * realloc: only conditionally expand backwards
+      * Try not to scavenge used bins
+      * Use bin counts as a guide to preallocation
+      * Occasionally bin return list chunks in first scan
+      * Add a few optimizations from colin@nyx10.cs.du.edu
+
+    V2.5.1 Sat Aug 14 15:40:43 1993  Doug Lea  (dl at g)
+      * faster bin computation & slightly different binning
+      * merged all consolidations to one part of malloc proper
+        (eliminating old malloc_find_space & malloc_clean_bin)
+      * Scan 2 returns chunks (not just 1)
+      * Propagate failure in realloc if malloc returns 0
+      * Add stuff to allow compilation on non-ANSI compilers
+         from kpv@research.att.com

+      * removed potential for odd address access in prev_chunk
+      * removed dependency on getpagesize.h
+      * misc cosmetics and a bit more internal documentation
+      * anticosmetics: mangled names in macros to evade debugger strangeness
+      * tested on sparc, hp-700, dec-mips, rs6000
+         with gcc & native cc (hp, dec only) allowing
+         Detlefs & Zorn comparison study (in SIGPLAN Notices.)
+
+    Trial version Fri Aug 28 13:14:29 1992  Doug Lea  (dl at g.oswego.edu)
+      * Based loosely on libg++-1.2X malloc. (It retains some of the overall
+        structure of old version,  but most details differ.)

+The Steps of Build Git with VS2008
+
+1. You need the build environment, which contains the Git dependencies
+   to be able to compile, link and run Git with MSVC.
+
+   You can either use the binary repository:
+
+       WWW: http://repo.or.cz/w/msvcgit.git
+       Git: git clone git://repo.or.cz/msvcgit.git
+       Zip: http://repo.or.cz/w/msvcgit.git?a=snapshot;h=master;sf=zip
+
+   and call the setup_32bit_env.cmd batch script before compiling Git,
+   (see repo/package README for details), or the source repository:
+
+       WWW: http://repo.or.cz/w/gitbuild.git
+       Git: git clone git://repo.or.cz/gitbuild.git
+       Zip: (None, as it's a project with submodules)
+
+   and build the support libs as instructed in that repo/package.
+
+2. Ensure you have the msysgit environment in your path, so you have
+   GNU Make, bash and perl available.
+
+       WWW: http://repo.or.cz/w/msysgit.git
+       Git: git clone git://repo.or.cz/msysgit.git
+       Zip: http://repo.or.cz/w/msysgit.git?a=snapshot;h=master;sf=zip
+
+   This environment is also needed when you use the resulting
+   executables, since Git might need to run scripts which are part of
+   the git operations.
+
+3. Inside Git's directory run the command:
+       make common-cmds.h
+   to generate the common-cmds.h file needed to compile git.
+
+4. Then either build Git with the GNU Make Makefile in the Git projects
+   root
+       make MSVC=1
+   or generate Visual Studio solution/projects (.sln/.vcproj) with the
+   command
+       perl contrib/buildsystems/generate -g Vcproj
+   and open and build the solution with the IDE
+       devenv git.sln /useenv
+   or build with the IDE build engine directly from the command line
+       devenv git.sln /useenv /build "Release|Win32"
+   The /useenv option is required, so Visual Studio picks up the
+   environment variables for the support libraries required to build
+   Git, which you set up in step 1.
+
+Done!

-===============

-NAME
-----
-git-difftool - compare changes using common merge tools
-
-SYNOPSIS
---------
-'git difftool' [--tool=<tool>] [--no-prompt] ['git diff' options]
-
-DESCRIPTION
------------
-'git-difftool' is a git command that allows you to compare and edit files
-between revisions using common merge tools.  At its most basic level,
-'git-difftool' does what 'git-mergetool' does but its use is for non-merge
-situations such as when preparing commits or comparing changes against
-the index.
-
-'git difftool' is a frontend to 'git diff' and accepts the same
-arguments and options.
-
-See linkgit:git-diff[1] for the full list of supported options.
-
-OPTIONS
--------
--t <tool>::
---tool=<tool>::
-       Use the merge resolution program specified by <tool>.
-       Valid merge tools are:
-       kdiff3, kompare, tkdiff, meld, xxdiff, emerge,
-       vimdiff, gvimdiff, ecmerge, and opendiff
-+
-If a merge resolution program is not specified, 'git-difftool'
-will use the configuration variable `merge.tool`.  If the
-configuration variable `merge.tool` is not set, 'git difftool'
-will pick a suitable default.
-+
-You can explicitly provide a full path to the tool by setting the
-configuration variable `mergetool.<tool>.path`. For example, you
-can configure the absolute path to kdiff3 by setting
-`mergetool.kdiff3.path`. Otherwise, 'git-difftool' assumes the
-tool is available in PATH.
-+
-Instead of running one of the known merge tool programs,
-'git-difftool' can be customized to run an alternative program
-by specifying the command line to invoke in a configuration
-variable `mergetool.<tool>.cmd`.
-+
-When 'git-difftool' is invoked with this tool (either through the
-`-t` or `--tool` option or the `merge.tool` configuration variable)
-the configured command line will be invoked with the following
-variables available: `$LOCAL` is set to the name of the temporary
-file containing the contents of the diff pre-image and `$REMOTE`
-is set to the name of the temporary file containing the contents
-of the diff post-image.  `$BASE` is provided for compatibility
-with custom merge tool commands and has the same value as `$LOCAL`.
-
---no-prompt::
-       Do not prompt before launching a diff tool.
-
-CONFIG VARIABLES
-----------------
-merge.tool::
-       The default merge tool to use.
-+
-See the `--tool=<tool>` option above for more details.
-
-merge.keepBackup::
-       The original, unedited file content can be saved to a file with
-       a `.orig` extension.  Defaults to `true` (i.e. keep the backup files).
-
-mergetool.<tool>.path::
-       Override the path for the given tool.  This is useful in case
-       your tool is not in the PATH.
-
-mergetool.<tool>.cmd::
-       Specify the command to invoke the specified merge tool.
-+
-See the `--tool=<tool>` option above for more details.
-

-
-linkgit:git-mergetool[1]::
-       Run merge conflict resolution tools to resolve merge conflicts
-
-linkgit:git-config[1]::

+=head1 NAME
+
+import-directories - Import bits and pieces to Git.
+
+=head1 SYNOPSIS
+
+B<import-directories.perl> F<configfile> F<outputfile>
+
+=head1 DESCRIPTION
+
+Script to import arbitrary projects version controlled by the "copy the
+source directory to a new location and edit it there"-version controlled
+projects into version control. Handles projects with arbitrary branching
+and version trees, taking a file describing the inputs and generating a
+file compatible with the L<git-fast-import(1)> format.
+
+=head1 CONFIGURATION FILE
+
+=head2 Format
+
+The configuration file is based on the standard I<.ini> format.
+
+ ; Comments start with semi-colons
+ [section]
+ key=value
+
+Please see below for information on how to escape special characters.
+
+=head2 Global configuration
+
+Global configuration is done in the B<[config]> section, which should be
+the first section in the file. Configuration can be changed by
+repeating configuration sections later on.
+
+ [config]
+ ; configure conversion of CRLFs. "convert" means that all CRLFs
+ ; should be converted into LFs (suitable for the core.autocrlf
+ ; setting set to true in Git). "none" means that all data is
+ ; treated as binary.
+ crlf=convert
+
+=head2 Revision configuration
+
+Each revision that is to be imported is described in three
+sections. Revisions should be defined in topological order, so
+that a revision's parent has always been defined when a new revision
+is introduced. All the sections for one revision must be defined
+before defining the next revision.
+
+Each revision is assigned a unique numerical identifier. The
+numbers do not need to be consecutive, nor monotonically
+increasing.
+
+For instance, if your configuration file contains only the two
+revisions 4711 and 42, where 4711 is the initial commit, the
+only requirement is that 4711 is completely defined before 42.
+
+=pod
+
+=head3 Revision description section
+
+A section whose section name is just an integer gives meta-data
+about the revision.
+
+ [3]
+ ; author sets the author of the revisions
+ author=Peter Krefting <peter@softwolves.pp.se>
+ ; branch sets the branch that the revision should be committed to
+ branch=master
+ ; parent describes the revision that is the parent of this commit
+ ; (optional)
+ parent=1
+ ; merges describes a revision that is merged into this commit
+ ; (optional; can be repeated)
+ merges=2
+ ; selects one file to take the timestamp from
+ ; (optional; if unspecified, the most recent file from the .files
+ ;  section is used)
+ timestamp=3/source.c
+
+=head3 Revision contents section
+
+A section whose section name is an integer followed by B<.files>
+describe all the files included in this revision. If a file that
+was available previously is not included in this revision, it will
+be removed.
+
+If an on-disk revision is incomplete, you can point to files from
+a previous revision. There are no restriction as to where the source
+files are located, nor to the names of them.
+
+ [3.files]
+ ; the key is the path inside the repository, the value is the path
+ ; as seen from the importer script.
+ source.c=ver-3.00/source.c
+ source.h=ver-2.99/source.h
+ readme.txt=ver-3.00/introduction to the project.txt
+
+File names are treated as byte strings (but please see below on
+quoting rules), and should be stored in the configuration file in
+the encoding that should be used in the generated repository.
+
+=head3 Revision commit message section
+
+A section whose section name is an integer followed by B<.message>
+gives the commit message. This section is read verbatim, up until
+the beginning of the next section. As such, a commit message may not
+contain a line that begins with an opening square bracket ("[") and
+ends with a closing square bracket ("]"), unless they are surrounded
+by whitespace or other characters.
+
+ [3.message]
+ Implement foobar.
+ ; trailing blank lines are ignored.

+=head2 Escaping special characters
+
+Key and value strings may be enclosed in quotes, in which case
+whitespace inside the quotes is preserved. Additionally, an equal
+sign may be included in the key by preceding it with a backslash.
+For example:
+
+ "key1 "=value1
+ key2=" value2"
+ key\=3=value3
+ key4=value=4
+ "key5""=value5
+
+Here the first key is "key1 " (note the trailing white-space) and the
+second value is " value2" (note the leading white-space). The third
+key contains an equal sign "key=3" and so does the fourth value, which
+does not need to be escaped. The fifth key contains a trailing quote,
+which does not need to be escaped since it is inside a surrounding
+quote.
+

+       # First remove enclosing quotes. Backslash before the trailing
+       # quote leaves both.

+
+If you do not want this feature on your server just remove the second rewrite rule.
+
+If you already use mod_userdir in your virtual host or you don't want to use
+the '~' as first character just comment or remove the second rewrite rule and

+
+Second, repositories found in /pub/scm/ and /var/git/ will be accesible
+through http://git.example.org/scm/ and http://git.example.org/var/.
+You can add as many project roots as you want by adding rewrite rules like the
+third and the fourth.

- *
- *    - if it is a hit, we are happy.
- *
- *    - if it is strictly higher than the target, we update hi with
- *      it.
- *
- *    - if it is strictly lower than the target, we update lo to be
- *      one slot after it, because we allow lo to be at the target.
- *
- * When choosing 'mi', we do not have to take the "middle" but
- * anywhere in between lo and hi, as long as lo <= mi < hi is
- * satisfied.  When we somehow know that the distance between the
- * target and lo is much shorter than the target and hi, we could
- * pick mi that is much closer to lo than the midway.

+When using GIT_TEST_INSTALLED, you can also set GIT_TEST_EXEC_PATH to

+And then we will see the scissors.

+This repository is for testing the ability to group revisions
+correctly along tags and branches.  Here is its history:
+
+  1.  The initial import (revision 1.1 of everybody) created a
+      directory structure with a file named `default' in each dir:
+
+            ./
+              default
+              sub1/default
+                   subsubA/default
+                   subsubB/default
+              sub2/default
+                   subsubA/default
+              sub3/default
+
+  2.  Then tagged everyone with T_ALL_INITIAL_FILES.
+
+  3.  Then tagged everyone except sub1/subsubB/default with
+      T_ALL_INITIAL_FILES_BUT_ONE.
+
+  4.  Then created branch B_FROM_INITIALS on everyone.
+
+  5.  Then created branch B_FROM_INITIALS_BUT_ONE on everyone except
+      /sub1/subsubB/default.
+
+  6.  Then committed modifications to two files: sub3/default, and
+      sub1/subsubA/default.
+
+  7.  Then committed a modification to all 7 files.
+
+  8.  Then backdated sub3/default to revision 1.2, and
+      sub2/subsubA/default to revision 1.1, and tagged with T_MIXED.
+
+  9.  Same as 8, but tagged with -b to create branch B_MIXED.
+
+  10. Switched the working copy to B_MIXED, and added
+      sub2/branch_B_MIXED_only.  (That's why the RCS file is in
+      sub2/Attic/ -- it never existed on trunk.)
+
+  11. In one commit, modified default, sub1/default, and
+      sub2/subsubA/default, on branch B_MIXED.
+
+  12. Did "cvs up -A" on sub2/default, then in one commit, made a
+      change to sub2/default and sub2/branch_B_MIXED_only.  So this
+      commit should be spread between the branch and the trunk.
+
+  13. Do "cvs up -A" to get everyone back to trunk, then make a new
+      branch B_SPLIT on everyone except sub1/subsubB/default,v.
+
+  14. Switch to branch B_SPLIT (see sub1/subsubB/default disappear)
+      and commit a change that affects everyone except sub3/default.
+
+  15. An hour or so later, "cvs up -A" to get sub1/subsubB/default
+      back, then commit a change on that file, on trunk.  (It's
+      important that this change happened after the previous commits
+      on B_SPLIT.)
+
+  16. Branch sub1/subsubB/default to B_SPLIT, then "cvs up -r B_SPLIT"
+      to switch the whole working copy to the branch.
+
+  17. Commit a change on B_SPLIT, to sub1/subsubB/default and
+      sub3/default.
