version.
core.sharedRepository::
- If true, the repository is made shareable between several users
- in a group (making sure all the files and objects are group-writable).
- See gitlink:git-init-db[1]. False by default.
+ When 'group' (or 'true'), the repository is made shareable between
+ several users in a group (making sure all the files and objects are
+ group-writable). When 'all' (or 'world' or 'everybody'), the
+ repository will be readable by all users, additionally to being
+ group-shareable. When 'umask' (or 'false'), git will use permissions
+ reported by umask(2). See gitlink:git-init-db[1]. False by default.
core.warnAmbiguousRefs::
If true, git will warn you if the ref name you passed it is ambiguous
and might match multiple refs in the .git/refs/ tree. True by default.
+core.compression::
+ An integer -1..9, indicating the compression level for objects that
+ are not in a pack file. -1 is the zlib and git default. 0 means no
+ compression, and 1..9 are various speed/size tradeoffs, 9 being
+ slowest.
+
+core.legacyheaders::
+ A boolean which enables the legacy object header format in case
+ you want to interoperate with old clients accessing the object
+ database directly (where the "http://" and "rsync://" protocols
+ count as direct access).
+
alias.*::
Command aliases for the gitlink:git[1] command wrapper - e.g.
after defining "alias.last = cat-file commit HEAD", the invocation
Tells `git-apply` how to handle whitespaces, in the same way
as the '--whitespace' option. See gitlink:git-apply[1].
+pager.color::
+ A boolean to enable/disable colored output when the pager is in
+ use (default is true).
+
+diff.color::
+ When true (or `always`), always use colors in patch.
+ When false (or `never`), never. When set to `auto`, use
+ colors only when the output is to the terminal.
+
+diff.color.<slot>::
+ Use customized color for diff colorization. `<slot>`
+ specifies which part of the patch to use the specified
+ color, and is one of `plain` (context text), `meta`
+ (metainformation), `frag` (hunk header), `old` (removed
+ lines), or `new` (added lines). The value for these
+ configuration variables can be one of: `normal`, `bold`,
+ `dim`, `ul`, `blink`, `reverse`, `reset`, `black`,
+ `red`, `green`, `yellow`, `blue`, `magenta`, `cyan`, or
+ `white`.
+
diff.renameLimit::
The number of files to consider when performing the copy/rename
detection; equivalent to the git diff option '-l'.
+diff.renames::
+ Tells git to detect renames. If set to any boolean value, it
+ will enable basic rename detection. If set to "copies" or
+ "copy", it will detect copies, as well.
+
format.headers::
Additional email headers to include in a patch to be submitted
by mail. See gitlink:git-format-patch[1].
Whether to include summaries of merged commits in newly created
merge commit messages. False by default.
+pack.window::
+ The size of the window used by gitlink:git-pack-objects[1] when no
+ window size is given on the command line. Defaults to 10.
+
pull.octopus::
The default merge strategy to use when pulling multiple branches
at once.
The default set of branches for gitlink:git-show-branch[1].
See gitlink:git-show-branch[1].
+tar.umask::
+ By default, gitlink:git-tar-tree[1] sets file and directories modes
+ to 0666 or 0777. While this is both useful and acceptable for projects
+ such as the Linux Kernel, it might be excessive for other projects.
+ With this variable, it becomes possible to tell
+ gitlink:git-tar-tree[1] to apply a specific umask to the modes above.
+ The special value "user" indicates that the user's current umask will
+ be used. This should be enough for most projects, as it will lead to
+ the same permissions as gitlink:git-checkout[1] would use. The default
+ value remains 0, which means world read-write.
+
user.email::
Your email address to be recorded in any newly created commits.
Can be overridden by the 'GIT_AUTHOR_EMAIL' and 'GIT_COMMITTER_EMAIL'

DESCRIPTION
A special notation <commit1>..<commit2> can be used as a

+Another special notation is <commit1>...<commit2> which is useful for

OPTIONS

Print the contents of the commit in raw-format; each
record is separated with a NUL character.
+--parents::

+
--objects::
Print the object IDs of any object referenced by the listed commits.
'git-rev-list --objects foo ^bar' thus means "send me all object IDs
--objects-edge::
Similar to `--objects`, but also print the IDs of
- excluded commits refixed with a `-` character. This is
+ excluded commits prefixed with a `-` character. This is
used by `git-pack-objects` to build 'thin' pack, which
records objects in deltified form based on objects

--remove-empty::
Stop when a given path disappears from the tree.
+--no-merges::
+ Do not print commits with more than one parent.
+
+--not::
+ Reverses the meaning of the '{caret}' prefix (or lack
+ thereof) for all following revision specifiers, up to

+SPECIFYING RANGES
+-----------------
+
+History traversing commands such as `git-log` operate on a set
+of commits, not just a single commit. To these commands,
+specifying a single revision with the notation described in the
+previous section means the set of commits reachable from that
+commit, following the commit ancestry chain.
+
+To exclude commits reachable from a commit, a prefix `{caret}`
+notation is used. E.g. "`{caret}r1 r2`" means commits reachable
+from `r2` but exclude the ones reachable from `r1`.
+
+This set operation appears so often that there is a shorthand
+for it. "`r1..r2`" is equivalent to "`{caret}r1 r2`". It is
+the difference of two sets (subtract the set of commits
+reachable from `r1` from the set of commits reachable from
+`r2`).
+
+A similar notation "`r1\...r2`" is called symmetric difference
+of `r1` and `r2` and is defined as
+"`r1 r2 --not $(git-merge-base --all r1 r2)`".
+It it the set of commits that are reachable from either one of
+`r1` or `r2` but not from both.
+
+Here are a few examples:
+
+ D A B D
+ D F A B C D F
+ ^A G B D
+ ^A F B C F
+ G...I C D F G I

+NAME
+----
+git-svn - bidirectional operation between a single Subversion branch and git
+
+SYNOPSIS
+--------
+'git-svn' <command> [options] [arguments]
+
+DESCRIPTION
+-----------
+git-svn is a simple conduit for changesets between a single Subversion
+branch and git.
+
+git-svn is not to be confused with git-svnimport. The were designed
+with very different goals in mind.
+
+git-svn is designed for an individual developer who wants a
+bidirectional flow of changesets between a single branch in Subversion
+and an arbitrary number of branches in git. git-svnimport is designed
+for read-only operation on repositories that match a particular layout
+(albeit the recommended one by SVN developers).
+
+For importing svn, git-svnimport is potentially more powerful when
+operating on repositories organized under the recommended
+trunk/branch/tags structure, and should be faster, too.
+
+git-svn mostly ignores the very limited view of branching that
+Subversion has. This allows git-svn to be much easier to use,
+especially on repositories that are not organized in a manner that
+git-svnimport is designed for.
+
+COMMANDS
+--------
+init::
+ Creates an empty git repository with additional metadata
+ directories for git-svn. The Subversion URL must be specified
+ as a command-line argument.
+
+fetch::
+ Fetch unfetched revisions from the Subversion URL we are
+ tracking. refs/remotes/git-svn will be updated to the
+ latest revision.
+
+ Note: You should never attempt to modify the remotes/git-svn
+ branch outside of git-svn. Instead, create a branch from
+ remotes/git-svn and work on that branch. Use the 'commit'
+ command (see below) to write git commits back to
+ remotes/git-svn.
+
+ See 'Additional Fetch Arguments' if you are interested in
+ manually joining branches on commit.
+
+commit::
+ Commit specified commit or tree objects to SVN. This relies on
+ your imported fetch data being up-to-date. This makes
+ absolutely no attempts to do patching when committing to SVN, it
+ simply overwrites files with those specified in the tree or
+ commit. All merging is assumed to have taken place
+ independently of git-svn functions.
+
+rebuild::
+ Not a part of daily usage, but this is a useful command if
+ you've just cloned a repository (using git-clone) that was
+ tracked with git-svn. Unfortunately, git-clone does not clone
+ git-svn metadata and the svn working tree that git-svn uses for
+ its operations. This rebuilds the metadata so git-svn can
+ resume fetch operations. A Subversion URL may be optionally
+ specified at the command-line if the directory/repository you're
+ tracking has moved or changed protocols.
+
+show-ignore::
+ Recursively finds and lists the svn:ignore property on
+ directories. The output is suitable for appending to
+ the $GIT_DIR/info/exclude file.
+
+OPTIONS
+-------
+-r <ARG>::
+--revision <ARG>::
+ Only used with the 'fetch' command.
+
+ Takes any valid -r<argument> svn would accept and passes it
+ directly to svn. -r<ARG1>:<ARG2> ranges and "{" DATE "}" syntax
+ is also supported. This is passed directly to svn, see svn
+ documentation for more details.
+
+ This can allow you to make partial mirrors when running fetch.
+
+-::
+--stdin::
+ Only used with the 'commit' command.
+
+ Read a list of commits from stdin and commit them in reverse
+ order. Only the leading sha1 is read from each line, so
+ git-rev-list --pretty=oneline output can be used.
+
+--rmdir::
+ Only used with the 'commit' command.
+
+ Remove directories from the SVN tree if there are no files left
+ behind. SVN can version empty directories, and they are not
+ removed by default if there are no files left in them. git
+ cannot version empty directories. Enabling this flag will make
+ the commit to SVN act like git.
+
+ repo-config key: svn.rmdir
+
+-e::
+--edit::
+ Only used with the 'commit' command.
+
+ Edit the commit message before committing to SVN. This is off by
+ default for objects that are commits, and forced on when committing
+ tree objects.
+
+ repo-config key: svn.edit
+
+-l<num>::
+--find-copies-harder::
+ Both of these are only used with the 'commit' command.
+
+ They are both passed directly to git-diff-tree see
+ git-diff-tree(1) for more information.
+
+ repo-config key: svn.l
+ repo-config key: svn.findcopiesharder
+
+-A<filename>::
+--authors-file=<filename>::
+
+ Syntax is compatible with the files used by git-svnimport and
+ git-cvsimport:
+
+------------------------------------------------------------------------
+loginname = Joe User <user@example.com>
+------------------------------------------------------------------------
+
+ If this option is specified and git-svn encounters an SVN
+ committer name that does not exist in the authors-file, git-svn
+ will abort operation. The user will then have to add the
+ appropriate entry. Re-running the previous git-svn command
+ after the authors-file is modified should continue operation.
+
+ repo-config key: svn.authors-file
+
+ADVANCED OPTIONS
+----------------
+-b<refname>::
+--branch <refname>::
+ Used with 'fetch' or 'commit'.
+
+ This can be used to join arbitrary git branches to remotes/git-svn
+ on new commits where the tree object is equivalent.
+
+ When used with different GIT_SVN_ID values, tags and branches in
+ SVN can be tracked this way, as can some merges where the heads
+ end up having completely equivalent content. This can even be
+ used to track branches across multiple SVN _repositories_.
+
+ This option may be specified multiple times, once for each
+ branch.
+
+ repo-config key: svn.branch
+
+-i<GIT_SVN_ID>::
+--id <GIT_SVN_ID>::
+ This sets GIT_SVN_ID (instead of using the environment). See
+ the section on "Tracking Multiple Repositories or Branches" for
+ more information on using GIT_SVN_ID.
+
+COMPATIBILITY OPTIONS
+---------------------
+--upgrade::
+ Only used with the 'rebuild' command.
+
+ Run this if you used an old version of git-svn that used
+ "git-svn-HEAD" instead of "remotes/git-svn" as the branch
+ for tracking the remote.
+
+--no-ignore-externals::
+ Only used with the 'fetch' and 'rebuild' command.
+
+ By default, git-svn passes --ignore-externals to svn to avoid
+ fetching svn:external trees into git. Pass this flag to enable
+ externals tracking directly via git.
+
+ Versions of svn that do not support --ignore-externals are
+ automatically detected and this flag will be automatically
+ enabled for them.
+
+ Otherwise, do not enable this flag unless you know what you're
+ doing.
+
+ repo-config key: svn.noignoreexternals
+
+Basic Examples
+~~~~~~~~~~~~~~
+
+Tracking and contributing to an Subversion managed-project:
+
+------------------------------------------------------------------------
+# Initialize a tree (like git init-db):
+ git-svn init http://svn.foo.org/project/trunk
+# Fetch remote revisions:
+ git-svn fetch
+# Create your own branch to hack on:
+ git checkout -b my-branch remotes/git-svn
+# Commit only the git commits you want to SVN:
+ git-svn commit <tree-ish> [<tree-ish_2> ...]
+# Commit all the git commits from my-branch that don't exist in SVN:
+ git-svn commit remotes/git-svn..my-branch
+# Something is committed to SVN, pull the latest into your branch:
+ git-svn fetch && git pull . remotes/git-svn
+# Append svn:ignore settings to the default git exclude file:
+ git-svn show-ignore >> .git/info/exclude
+------------------------------------------------------------------------
+
+DESIGN PHILOSOPHY
+-----------------
+Merge tracking in Subversion is lacking and doing branched development
+with Subversion is cumbersome as a result. git-svn completely forgoes
+any automated merge/branch tracking on the Subversion side and leaves it
+entirely up to the user on the git side. It's simply not worth it to do
+a useful translation when the original signal is weak.
+
+TRACKING MULTIPLE REPOSITORIES OR BRANCHES
+------------------------------------------
+This is for advanced users, most users should ignore this section.
+
+Because git-svn does not care about relationships between different
+branches or directories in a Subversion repository, git-svn has a simple
+hack to allow it to track an arbitrary number of related _or_ unrelated
+SVN repositories via one git repository. Simply set the GIT_SVN_ID
+environment variable to a name other other than "git-svn" (the default)
+and git-svn will ignore the contents of the $GIT_DIR/git-svn directory
+and instead do all of its work in $GIT_DIR/$GIT_SVN_ID for that
+invocation. The interface branch will be remotes/$GIT_SVN_ID, instead of
+remotes/git-svn. Any remotes/$GIT_SVN_ID branch should never be modified
+by the user outside of git-svn commands.
+
+ADDITIONAL FETCH ARGUMENTS
+--------------------------
+This is for advanced users, most users should ignore this section.
+
+Unfetched SVN revisions may be imported as children of existing commits
+by specifying additional arguments to 'fetch'. Additional parents may
+optionally be specified in the form of sha1 hex sums at the
+command-line. Unfetched SVN revisions may also be tied to particular
+git commits with the following syntax:
+
+ svn_revision_number=git_commit_sha1
+
+This allows you to tie unfetched SVN revision 375 to your current HEAD::
+
+ `git-svn fetch 375=$(git-rev-parse HEAD)`
+
+Advanced Example: Tracking a Reorganized Repository
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+If you're tracking a directory that has moved, or otherwise been
+branched or tagged off of another directory in the repository and you
+care about the full history of the project, then you can read this
+section.
+
+This is how Yann Dirson tracked the trunk of the ufoai directory when
+the /trunk directory of his repository was moved to /ufoai/trunk and
+he needed to continue tracking /ufoai/trunk where /trunk left off.
+
+------------------------------------------------------------------------
+ # This log message shows when the repository was reorganized:
+ r166 | ydirson | 2006-03-02 01:36:55 +0100 (Thu, 02 Mar 2006) | 1 line
+ Changed paths:
+ D /trunk
+ A /ufoai/trunk (from /trunk:165)
+
+ # First we start tracking the old revisions:
+ GIT_SVN_ID=git-oldsvn git-svn init \
+ https://svn.sourceforge.net/svnroot/ufoai/trunk
+ GIT_SVN_ID=git-oldsvn git-svn fetch -r1:165
+
+ # And now, we continue tracking the new revisions:
+ GIT_SVN_ID=git-newsvn git-svn init \
+ https://svn.sourceforge.net/svnroot/ufoai/ufoai/trunk
+ GIT_SVN_ID=git-newsvn git-svn fetch \
+ 166=`git-rev-parse refs/remotes/git-oldsvn`
+------------------------------------------------------------------------
+
+BUGS
+----
+If somebody commits a conflicting changeset to SVN at a bad moment
+(right before you commit) causing a conflict and your commit to fail,
+your svn working tree ($GIT_DIR/git-svn/tree) may be dirtied. The
+easiest thing to do is probably just to rm -rf $GIT_DIR/git-svn/tree and
+run 'rebuild'.
+
+We ignore all SVN properties except svn:executable. Too difficult to
+map them since we rely heavily on git write-tree being _exactly_ the
+same on both the SVN and git working trees and I prefer not to clutter
+working trees with metadata files.
+
+svn:keywords can't be ignored in Subversion (at least I don't know of
+a way to ignore them).
+
+Renamed and copied directories are not detected by git and hence not
+tracked when committing to SVN. I do not plan on adding support for
+this as it's quite difficult and time-consuming to get working for all
+the possible corner cases (git doesn't do it, either). Renamed and
+copied files are fully supported if they're similar enough for git to
+detect them.

+CONFIGURATION
+-------------
+By default, file and directories modes are set to 0666 or 0777. It is
+possible to change this by setting the "umask" variable in the
+repository configuration as follows :
+
+[tar]
+ umask = 002 ;# group friendly
+
+The special umask value "user" indicates that the user's current umask
+will be used instead. The default value remains 0, which means world
+readable/writable files and directories.
+

+Subject: Setting up a git repository which can be pushed into and pulled from over HTTP.
+Date: Thu, 10 Aug 2006 22:00:26 +0200
+
+Since Apache is one of those packages people like to compile
+themselves while others prefer the bureaucrat's dream Debian, it is
+impossible to give guidelines which will work for everyone. Just send
+some feedback to the mailing list at git@vger.kernel.org to get this
+document tailored to your favorite distro.
+
+
+What's needed:
+
+- Have an Apache web-server
+
+ On Debian:
+ $ apt-get install apache2
+ To get apache2 by default started,
+ edit /etc/default/apache2 and set NO_START=0
+
+- can edit the configuration of it.
+
+ This could be found under /etc/httpd, or refer to your Apache documentation.
+
+ On Debian: this means being able to edit files under /etc/apache2
+
+- can restart it.
+
+ 'apachectl --graceful' might do. If it doesn't, just stop and
+ restart apache. Be warning that active connections to your server
+ might be aborted by this.
+
+ On Debian:
+ $ /etc/init.d/apache2 restart
+ or
+ $ /etc/init.d/apache2 force-reload
+ (which seems to do the same)
+ This adds symlinks from the /etc/apache2/mods-enabled to
+ /etc/apache2/mods-available.
+
+- have permissions to chown a directory
+
+- have git installed at the server _and_ client
+
+In effect, this probably means you're going to be root.
+
+
+Step 1: setup a bare GIT repository
+-----------------------------------
+
+At the time of writing, git-http-push cannot remotely create a GIT
+repository. So we have to do that at the server side with git. Another
+option would be to generate an empty repository at the client and copy
+it to the server with WebDAV. But then you're probably the first to
+try that out :)
+
+Create the directory under the DocumentRoot of the directories served
+by Apache. As an example we take /usr/local/apache2, but try "grep
+DocumentRoot /where/ever/httpd.conf" to find your root:
+
+ $ cd /usr/local/apache/htdocs
+ $ mkdir my-new-repo.git
+
+ On Debian:
+
+ $ cd /var/www
+ $ mkdir my-new-repo.git
+
+
+Initialize a bare repository
+
+ $ cd my-new-repo.git
+ $ git --bare init-db
+
+
+Change the ownership to your web-server's credentials. Use "grep ^User
+httpd.conf" and "grep ^Group httpd.conf" to find out:
+
+ $ chown -R www.www .
+
+ On Debian:
+
+ $ chown -R www-data.www-data .
+
+
+If you do not know which user Apache runs as, you can alternatively do
+a "chmod -R a+w .", inspect the files which are created later on, and
+set the permissions appropriately.
+
+Restart apache2, and check whether http://server/my-new-repo.git gives
+a directory listing. If not, check whether apache started up
+successfully.
+
+
+Step 2: enable DAV on this repository
+-------------------------------------
+
+First make sure the dav_module is loaded. For this, insert in httpd.conf:
+
+ LoadModule dav_module libexec/httpd/libdav.so
+ AddModule mod_dav.c
+
+Also make sure that this line exists which is the file used for
+locking DAV operations:
+
+ DAVLockDB "/usr/local/apache2/temp/DAV.lock"
+
+ On Debian these steps can be performed with:
+
+ Enable the dav and dav_fs modules of apache:
+ $ a2enmod dav_fs
+ (just to be sure. dav_fs might be unneeded, I don't know)
+ $ a2enmod dav
+ The DAV lock is located in /etc/apache2/mods-available/dav_fs.conf:
+ DAVLockDB /var/lock/apache2/DAVLock
+
+Of course, it can point somewhere else, but the string is actually just a
+prefix in some Apache configurations, and therefore the _directory_ has to
+be writable by the user Apache runs as.
+
+Then, add something like this to your httpd.conf
+
+ <Location /my-new-repo.git>
+ DAV on
+ AuthType Basic
+ AuthName "Git"
+ AuthUserFile /usr/local/apache2/conf/passwd.git
+ Require valid-user
+ </Location>
+
+ On Debian:
+ Create (or add to) /etc/apache2/conf.d/git.conf :
+
+ <Location /my-new-repo.git>
+ DAV on
+ AuthType Basic
+ AuthName "Git"
+ AuthUserFile /etc/apache2/passwd.git
+ Require valid-user
+ </Location>
+
+ Debian automatically reads all files under /etc/apach2/conf.d.
+
+The password file can be somewhere else, but it has to be readable by
+Apache and preferably not readable by the world.
+
+Create this file by
+ $ htpasswd -c /usr/local/apache2/conf/passwd.git <user>
+
+ On Debian:
+ $ htpasswd -c /etc/apache2/passwd.git <user>
+
+You will be asked a password, and the file is created. Subsequent calls
+to htpasswd should omit the '-c' option, since you want to append to the
+existing file.
+
+You need to restart Apache.
+
+Now go to http://<username>@<servername>/my-new-repo.git in your
+browser to check whether it asks for a password and accepts the right
+password.
+
+On Debian:
+
+ To test the WebDAV part, do:
+
+ $ apt-get install litmus
+ $ litmus http://<servername>/my-new-repo.git <username> <password>
+
+ Most tests should pass.
+
+A command line tool to test WebDAV is cadaver.
+
+If you're into Windows, from XP onwards Internet Explorer supports
+WebDAV. For this, do Internet Explorer -> Open Location ->
+http://<servername>/my-new-repo.git [x] Open as webfolder -> login .
+
+
+Step 3: setup the client
+------------------------
+
+Make sure that you have HTTP support, i.e. your git was built with curl.
+The easiest way to check is to look for the executable 'git-http-push'.
+
+Then, add the following to your $HOME/.netrc (you can do without, but will be
+asked to input your password a _lot_ of times):
+
+ machine <servername>
+ login <username>
+ password <password>
+
+...and set permissions:
+ chmod 600 ~/.netrc
+
+If you want to access the web-server by its IP, you have to type that in,
+instead of the server name.
+
+To check whether all is OK, do:
+
+ curl --netrc --location -v http://<username>@<servername>/my-new-repo.git/
+
+...this should give a directory listing in HTML of /var/www/my-new-repo.git .
+
+
+Now, add the remote in your existing repository which contains the project
+you want to export:
+
+ $ git-repo-config remote.upload.url \
+ http://<username>@<servername>/my-new-repo.git/
+
+It is important to put the last '/'; Without it, the server will send
+a redirect which git-http-push does not (yet) understand, and git-http-push
+will repeat the request infinitely.
+
+
+Step 4: make the initial push
+-----------------------------
+
+From your client repository, do
+
+ $ git push upload master
+
+This pushes branch 'master' (which is assumed to be the branch you
+want to export) to repository called 'upload', which we previously
+defined with git-repo-config.
+
+
+Troubleshooting:
+----------------
+
+If git-http-push says
+
+ Error: no DAV locking support on remote repo http://...
+
+then it means the web-server did not accept your authentication. Make sure
+that the user name and password matches in httpd.conf, .netrc and the URL
+you are uploading to.
+
+If git-http-push shows you an error (22/502) when trying to MOVE a blob,
+it means that your web-server somehow does not recognize its name in the
+request; This can happen when you start Apache, but then disable the
+network interface. A simple restart of Apache helps.
+
+Errors like (22/502) are of format (curl error code/http error
+code). So (22/404) means something like 'not found' at the server.
+
+Reading /usr/local/apache2/logs/error_log is often helpful.
+
+ On Debian: Read /var/log/apache2/error.log instead.

+ * git-checkout-index -a -f file.c
+ *
+ * Will first check out all files listed in the cache (but not
+ * overwrite any old ones), and then force-checkout "file.c" a

+ *
+ * Also, just doing "git-checkout-index" does nothing. You probably
+ * meant "git-checkout-index -a". And if you want to force it, you
+ * want "git-checkout-index -f -a".
+ *
+ * Intuitiveness is not the goal here. Repeatability is. The
+ * reason for the "no arguments means no work" thing is that
+ * from scripts you are supposed to be able to do things like
+ *
+ * find . -name '*.h' -print0 | xargs -0 git-checkout-index -f --
+ *
+ * or:
+ *
+ * find . -name '*.h' -print0 | git-checkout-index -f -z --stdin
+ *
+ * which will force all existing *.h files to be replaced with
+ * their cached copies. If an empty command line implied "all",
+ * then this would force-refresh everything in the cache, which
+ * was not the point.
+ *
+ * Oh, and the "--" is just a good idea when you know the rest
+ * will be filenames. Just so that you wouldn't have a filename
+ * of "-a" causing problems (not possible in the above example,

- * Check-out files from the "current cache directory"
- *
- * Copyright (C) 2005 Linus Torvalds
- *
- * Careful: order of argument flags does matter. For example,
- *
- * git-checkout-index -a -f file.c
- *
- * Will first check out all files listed in the cache (but not
- * overwrite any old ones), and then force-checkout "file.c" a
- * second time (ie that one _will_ overwrite any old contents
- * with the same filename).
- *
- * Also, just doing "git-checkout-index" does nothing. You probably
- * meant "git-checkout-index -a". And if you want to force it, you
- * want "git-checkout-index -f -a".
- *
- * Intuitiveness is not the goal here. Repeatability is. The
- * reason for the "no arguments means no work" thing is that
- * from scripts you are supposed to be able to do things like
- *
- * find . -name '*.h' -print0 | xargs -0 git-checkout-index -f --
- *
- * or:
- *
- * find . -name '*.h' -print0 | git-checkout-index -f -z --stdin
- *
- * which will force all existing *.h files to be replaced with
- * their cached copies. If an empty command line implied "all",
- * then this would force-refresh everything in the cache, which
- * was not the point.
- *
- * Oh, and the "--" is just a good idea when you know the rest
- * will be filenames. Just so that you wouldn't have a filename
- * of "-a" causing problems (not possible in the above example,
- * but get used to it in scripting!).

-NAME
-----
-git-svn - bidirectional operation between a single Subversion branch and git
-
-SYNOPSIS
---------
-'git-svn' <command> [options] [arguments]
-
-DESCRIPTION
------------
-git-svn is a simple conduit for changesets between a single Subversion
-branch and git.
-
-git-svn is not to be confused with git-svnimport. The were designed
-with very different goals in mind.
-
-git-svn is designed for an individual developer who wants a
-bidirectional flow of changesets between a single branch in Subversion
-and an arbitrary number of branches in git. git-svnimport is designed
-for read-only operation on repositories that match a particular layout
-(albeit the recommended one by SVN developers).
-
-For importing svn, git-svnimport is potentially more powerful when
-operating on repositories organized under the recommended
-trunk/branch/tags structure, and should be faster, too.
-
-git-svn mostly ignores the very limited view of branching that
-Subversion has. This allows git-svn to be much easier to use,
-especially on repositories that are not organized in a manner that
-git-svnimport is designed for.
-
-COMMANDS
---------
-init::
- Creates an empty git repository with additional metadata
- directories for git-svn. The Subversion URL must be specified
- as a command-line argument.
-
-fetch::
- Fetch unfetched revisions from the Subversion URL we are
- tracking. refs/remotes/git-svn will be updated to the
- latest revision.
-
- Note: You should never attempt to modify the remotes/git-svn
- branch outside of git-svn. Instead, create a branch from
- remotes/git-svn and work on that branch. Use the 'commit'
- command (see below) to write git commits back to
- remotes/git-svn.
-
- See 'Additional Fetch Arguments' if you are interested in
- manually joining branches on commit.
-
-commit::
- Commit specified commit or tree objects to SVN. This relies on
- your imported fetch data being up-to-date. This makes
- absolutely no attempts to do patching when committing to SVN, it
- simply overwrites files with those specified in the tree or
- commit. All merging is assumed to have taken place
- independently of git-svn functions.
-
-rebuild::
- Not a part of daily usage, but this is a useful command if
- you've just cloned a repository (using git-clone) that was
- tracked with git-svn. Unfortunately, git-clone does not clone
- git-svn metadata and the svn working tree that git-svn uses for
- its operations. This rebuilds the metadata so git-svn can
- resume fetch operations. A Subversion URL may be optionally
- specified at the command-line if the directory/repository you're
- tracking has moved or changed protocols.
-
-show-ignore::
- Recursively finds and lists the svn:ignore property on
- directories. The output is suitable for appending to
- the $GIT_DIR/info/exclude file.
-
-OPTIONS
--------
--r <ARG>::
---revision <ARG>::
- Only used with the 'fetch' command.
-
- Takes any valid -r<argument> svn would accept and passes it
- directly to svn. -r<ARG1>:<ARG2> ranges and "{" DATE "}" syntax
- is also supported. This is passed directly to svn, see svn
- documentation for more details.
-
- This can allow you to make partial mirrors when running fetch.
-
--::
---stdin::
- Only used with the 'commit' command.
-
- Read a list of commits from stdin and commit them in reverse
- order. Only the leading sha1 is read from each line, so
- git-rev-list --pretty=oneline output can be used.
-
---rmdir::
- Only used with the 'commit' command.
-
- Remove directories from the SVN tree if there are no files left
- behind. SVN can version empty directories, and they are not
- removed by default if there are no files left in them. git
- cannot version empty directories. Enabling this flag will make
- the commit to SVN act like git.
-
- repo-config key: svn.rmdir
-
--e::
---edit::
- Only used with the 'commit' command.
-
- Edit the commit message before committing to SVN. This is off by
- default for objects that are commits, and forced on when committing
- tree objects.
-
- repo-config key: svn.edit
-
--l<num>::
---find-copies-harder::
- Both of these are only used with the 'commit' command.
-
- They are both passed directly to git-diff-tree see
- git-diff-tree(1) for more information.
-
- repo-config key: svn.l
- repo-config key: svn.findcopiesharder
-
--A<filename>::
---authors-file=<filename>::
-
- Syntax is compatible with the files used by git-svnimport and
- git-cvsimport:
-
-------------------------------------------------------------------------
-loginname = Joe User <user@example.com>
-------------------------------------------------------------------------
-
- If this option is specified and git-svn encounters an SVN
- committer name that does not exist in the authors-file, git-svn
- will abort operation. The user will then have to add the
- appropriate entry. Re-running the previous git-svn command
- after the authors-file is modified should continue operation.
-
- repo-config key: svn.authors-file
-
-ADVANCED OPTIONS
-----------------
--b<refname>::
---branch <refname>::
- Used with 'fetch' or 'commit'.
-
- This can be used to join arbitrary git branches to remotes/git-svn
- on new commits where the tree object is equivalent.
-
- When used with different GIT_SVN_ID values, tags and branches in
- SVN can be tracked this way, as can some merges where the heads
- end up having completely equivalent content. This can even be
- used to track branches across multiple SVN _repositories_.
-
- This option may be specified multiple times, once for each
- branch.
-
- repo-config key: svn.branch
-
--i<GIT_SVN_ID>::
---id <GIT_SVN_ID>::
- This sets GIT_SVN_ID (instead of using the environment). See
- the section on "Tracking Multiple Repositories or Branches" for
- more information on using GIT_SVN_ID.
-
-COMPATIBILITY OPTIONS
----------------------
---upgrade::
- Only used with the 'rebuild' command.
-
- Run this if you used an old version of git-svn that used
- "git-svn-HEAD" instead of "remotes/git-svn" as the branch
- for tracking the remote.
-
---no-ignore-externals::
- Only used with the 'fetch' and 'rebuild' command.
-
- By default, git-svn passes --ignore-externals to svn to avoid
- fetching svn:external trees into git. Pass this flag to enable
- externals tracking directly via git.
-
- Versions of svn that do not support --ignore-externals are
- automatically detected and this flag will be automatically
- enabled for them.
-
- Otherwise, do not enable this flag unless you know what you're
- doing.
-
- repo-config key: svn.noignoreexternals
-
-Basic Examples
-~~~~~~~~~~~~~~
-
-Tracking and contributing to an Subversion managed-project:
-
-------------------------------------------------------------------------
-# Initialize a tree (like git init-db):
- git-svn init http://svn.foo.org/project/trunk
-# Fetch remote revisions:
- git-svn fetch
-# Create your own branch to hack on:
- git checkout -b my-branch remotes/git-svn
-# Commit only the git commits you want to SVN:
- git-svn commit <tree-ish> [<tree-ish_2> ...]
-# Commit all the git commits from my-branch that don't exist in SVN:
- git-svn commit remotes/git-svn..my-branch
-# Something is committed to SVN, pull the latest into your branch:
- git-svn fetch && git pull . remotes/git-svn
-# Append svn:ignore settings to the default git exclude file:
- git-svn show-ignore >> .git/info/exclude
-------------------------------------------------------------------------
-
-DESIGN PHILOSOPHY
------------------
-Merge tracking in Subversion is lacking and doing branched development
-with Subversion is cumbersome as a result. git-svn completely forgoes
-any automated merge/branch tracking on the Subversion side and leaves it
-entirely up to the user on the git side. It's simply not worth it to do
-a useful translation when the the original signal is weak.
-
-TRACKING MULTIPLE REPOSITORIES OR BRANCHES
-------------------------------------------
-This is for advanced users, most users should ignore this section.
-
-Because git-svn does not care about relationships between different
-branches or directories in a Subversion repository, git-svn has a simple
-hack to allow it to track an arbitrary number of related _or_ unrelated
-SVN repositories via one git repository. Simply set the GIT_SVN_ID
-environment variable to a name other other than "git-svn" (the default)
-and git-svn will ignore the contents of the $GIT_DIR/git-svn directory
-and instead do all of its work in $GIT_DIR/$GIT_SVN_ID for that
-invocation. The interface branch will be remotes/$GIT_SVN_ID, instead of
-remotes/git-svn. Any remotes/$GIT_SVN_ID branch should never be modified
-by the user outside of git-svn commands.
-
-ADDITIONAL FETCH ARGUMENTS
---------------------------
-This is for advanced users, most users should ignore this section.
-
-Unfetched SVN revisions may be imported as children of existing commits
-by specifying additional arguments to 'fetch'. Additional parents may
-optionally be specified in the form of sha1 hex sums at the
-command-line. Unfetched SVN revisions may also be tied to particular
-git commits with the following syntax:
-
- svn_revision_number=git_commit_sha1
-
-This allows you to tie unfetched SVN revision 375 to your current HEAD::
-
- `git-svn fetch 375=$(git-rev-parse HEAD)`
-
-Advanced Example: Tracking a Reorganized Repository
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-If you're tracking a directory that has moved, or otherwise been
-branched or tagged off of another directory in the repository and you
-care about the full history of the project, then you can read this
-section.
-
-This is how Yann Dirson tracked the trunk of the ufoai directory when
-the /trunk directory of his repository was moved to /ufoai/trunk and
-he needed to continue tracking /ufoai/trunk where /trunk left off.
-
-------------------------------------------------------------------------
- # This log message shows when the repository was reorganized:
- r166 | ydirson | 2006-03-02 01:36:55 +0100 (Thu, 02 Mar 2006) | 1 line
- Changed paths:
- D /trunk
- A /ufoai/trunk (from /trunk:165)
-
- # First we start tracking the old revisions:
- GIT_SVN_ID=git-oldsvn git-svn init \
- https://svn.sourceforge.net/svnroot/ufoai/trunk
- GIT_SVN_ID=git-oldsvn git-svn fetch -r1:165
-
- # And now, we continue tracking the new revisions:
- GIT_SVN_ID=git-newsvn git-svn init \
- https://svn.sourceforge.net/svnroot/ufoai/ufoai/trunk
- GIT_SVN_ID=git-newsvn git-svn fetch \
- 166=`git-rev-parse refs/remotes/git-oldsvn`
-------------------------------------------------------------------------
-
-BUGS
-----
-If somebody commits a conflicting changeset to SVN at a bad moment
-(right before you commit) causing a conflict and your commit to fail,
-your svn working tree ($GIT_DIR/git-svn/tree) may be dirtied. The
-easiest thing to do is probably just to rm -rf $GIT_DIR/git-svn/tree and
-run 'rebuild'.
-
-We ignore all SVN properties except svn:executable. Too difficult to
-map them since we rely heavily on git write-tree being _exactly_ the
-same on both the SVN and git working trees and I prefer not to clutter
-working trees with metadata files.
-
-svn:keywords can't be ignored in Subversion (at least I don't know of
-a way to ignore them).
-
-Renamed and copied directories are not detected by git and hence not
-tracked when committing to SVN. I do not plan on adding support for
-this as it's quite difficult and time-consuming to get working for all
-the possible corner cases (git doesn't do it, either). Renamed and
-copied files are fully supported if they're similar enough for git to
-detect them.

From the git version 1.4.0 gitweb is bundled with git.
-Any comment/question/concern to:
+
+How to configure gitweb for your local system:
+
+You can specify the following configuration variables when building GIT:
+ * GITWEB_SITENAME
+ Shown in the title of all generated pages, defaults to the servers name.
+ * GITWEB_PROJECTROOT
+ The root directory for all projects shown by gitweb.
+ * GITWEB_LIST
+ points to a directory to scan for projects (defaults to project root)
+ or to a file for explicit listing of projects.
+ * GITWEB_HOMETEXT
+ points to an .html file which is included on the gitweb project
+ overview page.
+ * GITWEB_CSS
+ Points to the location where you put gitweb.css on your web server.
+ * GITWEB_LOGO
+ Points to the location where you put git-logo.png on your web server.
+ * GITWEB_CONFIG
+ This file will be loaded using 'require'. If the environment
+ $GITWEB_CONFIG is set when gitweb.cgi is executed the file in the
+ environment variable will be loaded instead of the file
+ specified when gitweb.cgi was created.

- * A pathological example of how this thing works.
- *
- * Suppose we had this commit graph, where chronologically
- * the timestamp on the commit are A <= B <= C <= D <= E <= F
- * and we are trying to figure out the merge base for E and F
- * commits.
- *
- * F
- * / \
- * E A D
- * \ / /
- * B /
- * \ /
- * C
- *
- * First we push E and F to list to be processed. E gets bit 1
- * and F gets bit 2. The list becomes:
- *
- * list=F(2) E(1), result=empty
- *
- * Then we pop F, the newest commit, from the list. Its flag is 2.
- * We scan its parents, mark them reachable from the side that F is
- * reachable from, and push them to the list:
- *
- * list=E(1) D(2) A(2), result=empty
- *
- * Next pop E and do the same.
- *
- * list=D(2) B(1) A(2), result=empty
- *
- * Next pop D and do the same.
- *
- * list=C(2) B(1) A(2), result=empty
- *
- * Next pop C and do the same.
- *
- * list=B(1) A(2), result=empty
- *
- * Now it is B's turn. We mark its parent, C, reachable from B's side,
- * and push it to the list:
- *
- * list=C(3) A(2), result=empty
- *
- * Now pop C and notice it has flags==3. It is placed on the result list,
- * and the list now contains:
- *
- * list=A(2), result=C(3)
- *
- * We pop A and do the same.
- *
- * list=B(3), result=C(3)
- *
- * Next, we pop B and something very interesting happens. It has flags==3
- * so it is also placed on the result list, and its parents are marked
- * uninteresting, retroactively, and placed back on the list:
- *
- * list=C(7), result=C(7) B(3)
- *
- * Now, list does not have any interesting commit. So we find the newest
- * commit from the result list that is not marked uninteresting. Which is
- * commit B.
- *
- *
- * Another pathological example how this thing used to fail to mark an
- * ancestor of a merge base as UNINTERESTING before we introduced the
- * postprocessing phase (mark_reachable_commits).
- *

- * 1 / \
- * G A \
- * |\ / \
- * | B \
- * | \ \
- * \ C F
- * \ \ /
- * \ D /
- * \ | /
- * \| /
- * E
- *
- * list A B C D E F G H
- * G1 H2 - - - - - - 1 2
- * H2 E1 B1 - 1 - - 1 - 1 2
- * F2 E1 B1 A2 2 1 - - 1 2 1 2
- * E3 B1 A2 2 1 - - 3 2 1 2
- * B1 A2 2 1 - - 3 2 1 2
- * C1 A2 2 1 1 - 3 2 1 2

- * B3 2 3 1 1 3 2 1 2
- * C7 2 3 7 1 3 2 1 2
- *
- * At this point, unfortunately, everybody in the list is
- * uninteresting, so we fail to complete the following two
- * steps to fully marking uninteresting commits.
- *
- * D7 2 3 7 7 3 2 1 2
- * E7 2 3 7 7 7 2 1 2
- *
- * and we ended up showing E as an interesting merge base.
- * The postprocessing phase re-injects C and continues traversal
- * to contaminate D and E.

+ * Then the variables are renamed: (A,B,C,D,E) = (E,A,B,C,D).
+ *
+ * Every 20 rounds, the function F() and the contant K changes:
+ * - 20 rounds of f0(b,c,d) = "bit wise b ? c : d" = (^b & d) + (b & c)
+ * - 20 rounds of f1(b,c,d) = b^c^d = (b^d)^c
+ * - 20 rounds of f2(b,c,d) = majority(b,c,d) = (b&d) + ((b^d)&c)
+ * - 20 more rounds of f1(b,c,d)
+ *
+ * These are all scheduled for near-optimal performance on a G4.
+ * The G4 is a 3-issue out-of-order machine with 3 ALUs, but it can only
+ * *consider* starting the oldest 3 instructions per cycle. So to get
+ * maximum performace out of it, you have to treat it as an in-order
+ * machine. Which means interleaving the computation round t with the
+ * computation of W[t+4].
+ *
+ * The first 16 rounds use W values loaded directly from memory, while the
+ * remaining 64 use values computed from those first 16. We preload
+ * 4 values before starting, so there are three kinds of rounds:
+ * - The first 12 (all f0) also load the W values from memory.
+ * - The next 64 compute W(i+4) in parallel. 8*f0, 20*f1, 20*f2, 16*f1.
+ * - The last 4 (all f1) do not do anything with W.
+ *
+ * Therefore, we have 6 different round functions:
+ * STEPD0_LOAD(t,s) - Perform round t and load W(s). s < 16
+ * STEPD0_UPDATE(t,s) - Perform round t and compute W(s). s >= 16.
+ * STEPD1_UPDATE(t,s)
+ * STEPD2_UPDATE(t,s)
+ * STEPD1(t) - Perform round t with no load or update.
+ *
+ * The G5 is more fully out-of-order, and can find the parallelism
+ * by itself. The big limit is that it has a 2-cycle ALU latency, so
+ * even though it's 2-way, the code has to be scheduled as if it's
+ * 4-way, which can be a limit. To help it, we try to schedule the
+ * read of RA(t) as late as possible so it doesn't stall waiting for
+ * the previous round's RE(t-1), and we try to rotate RB(t) as early
+ * as possible while reading RC(t) (= RB(t-1)) as late as possible.
