Updates since v1.5.2
--------------------
-* An initial interation of Porcelain level superproject support
- started to take shape.
-
-* Thee are a handful pack-objects changes to help you cope better with
- repositories with pathologically large blobs in them.
+* The commit walkers other than http are officially deprecated,
+ but still supported for now.
+
+* The submodule support has Porcelain layer.
+
+ Note that the current submodule support is minimal and this is
+ deliberately so. A design decision we made is that operations
+ at the supermodule level do not recurse into submodules by
+ default. The expectation is that later we would add a
+ mechanism to tell git which submodules the user is interested
+ in, and this information might be used to determine the
+ recursive behaviour of certain commands (e.g. "git checkout"
+ and "git diff"), but currently we haven't agreed on what that
+ mechanism should look like. Therefore, if you use submodules,
+ you would probably need "git submodule update" on the
+ submodules you care about after running a "git checkout" at
+ the supermodule level.
+
+* There are a handful pack-objects changes to help you cope better
+ with repositories with pathologically large blobs in them.
* For people who need to import from Perforce, a front-end for
- fast-import is in contrib/fast-import/ now.
+ fast-import is in contrib/fast-import/.
* Comes with git-gui 0.8.0.
* New commands and options.
- - "git log" learned a new option '--follow', to follow
+ - "git log --date=<format>" can use more formats: iso8601, rfc2822.
+
+ - The hunk header output from "git diff" family can be customized
+ with the attributes mechanism. See gitattributes(5) for details.
+
+ - "git stash" allows you to quickly save away your work in
+ progress and replay it later on an updated state.
+
+ - "git rebase" learned an "interactive" mode that let you
+ pick and reorder which commits to rebuild.
+
+ - "git fsck" can save its findings in $GIT_DIR/lost-found, without a
+ separate invocation of "git lost-found" command. The blobs stored by
+ lost-found are stored in plain format to allow you to grep in them.
+
+ - $GIT_WORK_TREE environment variable can be used together with
+ $GIT_DIR to work in a subdirectory of a working tree that is
+ not located at "$GIT_DIR/..".
+
+ - Giving "--file=<file>" option to "git config" is the same as
+ running the command with GIT_CONFIG=<file> environment.
+
+ - "git log" learned a new option "--follow", to follow
renaming history of a single file.
- - "git-filter-branch" is a reborn cg-admin-rewritehist.
+ - "git filter-branch" lets you rewrite the revision history of
+ specified branches. You can specify a number of filters to
+ modify the commits, files and trees.
+
+ - "git cvsserver" learned new options (--base-path, --export-all,
+ --strict-paths) inspired by "git daemon".
- - "git-cvsserver" learned new options (--base-path, --export-all,
- --strict-paths) inspired by git-daemon.
+ - "git daemon --base-path-relaxed" can help migrating a repository URL
+ that did not use to use --base-path to use --base-path.
- - "git-submodule" command helps you manage the projects from
+ - "git commit" can use "-t templatefile" option and commit.template
+ configuration variable to prime the commit message given to you in the
+ editor.
+
+ - "git submodule" command helps you manage the projects from
the superproject that contain them.
- In addition to core.compression configuration option,
independently tweak zlib compression levels used for loose
and packed objects.
- - "git-ls-tree -l" shows size of blobs pointed at by the
+ - "git ls-tree -l" shows size of blobs pointed at by the
tree entries, similar to "/bin/ls -l".
- - "git-rev-list" learned --regexp-ignore-case and
+ - "git rev-list" learned --regexp-ignore-case and
--extended-regexp options to tweak its matching logic used
for --grep fitering.
- - "git-describe --contains" is a handier way to call more
- obscure command "git-name-rev --tags".
+ - "git describe --contains" is a handier way to call more
+ obscure command "git name-rev --tags".
- "git gc --aggressive" tells the command to spend more cycles
to optimize the repository harder.
+ - "git repack" learned a "window-memory" limit which
+ dynamically reduces the window size to stay within the
+ specified memory usage.
+
- "git repack" can be told to split resulting packs to avoid
exceeding limit specified with "--max-pack-size".
- "git format-patch" learned --numbered-files option. This
may be useful for MH users.
+ - "git format-patch" learned format.subjectprefix configuration
+ variable, which serves the same purpose as "--subject-prefix"
+ option.
+
- "git tag -n -l" shows tag annotations while listing tags.
- "git cvsimport" can optionally use the separate-remote layout.
- - "git blame" can be told to see through commits that changes
+ - "git blame" can be told to see through commits that change
whitespaces and indentation levels with "-w" option.
- "git send-email" can be told not to thread the messages when
- "git config" learned NUL terminated output format via -z to
help scripts.
+ - "git add" learned "--refresh <paths>..." option to selectively refresh
+ the cached stat information.
+
+ - "git init -q" makes the command quieter.
+
* Updated behavior of existing commands.
+ - "gitweb" can offer multiple snapshot formats.
+
+ ***NOTE*** Unfortunately, this changes the format of the
+ $feature{snapshot}{default} entry in the per-site
+ configuration file 'gitweb_config.perl'. It used to be a
+ three-element tuple that describe a single format; with the
+ new configuration item format, you only have to say the name
+ of the format ('tgz', 'tbz2' or 'zip'). Please update the
+ your configuration file accordingly.
+
+ - "git clone" uses -l (hardlink files under .git) by default when
+ cloning locally.
+
+ - "git bundle create" can now create a bundle without negative refs,
+ i.e. "everything since the beginning up to certain points".
+
+ - "git diff" (but not the plumbing level "git diff-tree") now
+ recursively descends into trees by default.
+
+ - "git diff" does not show differences that come only from
+ stat-dirtiness in the form of "diff --git" header anymore. When
+ generating a textual diff, it shows a warning message at the end.
+
+ - The editor to use with many interactive commands can be
+ overridden with GIT_EDITOR environment variable, or if it
+ does not exist, with core.editor configuration variable. As
+ before, if you have neither, environment variables VISUAL
+ and EDITOR are consulted in this order, and then finally we
+ fall back on "vi".
+
+ - "git rm --cached" does not complain when removing a newly
+ added file from the index anymore.
+
+ - Options to "git log" to affect how --grep/--author options look for
+ given strings now have shorter abbreviations. -i is for ignore case,
+ and -E is for extended regexp.
+
+ - "git log" learned --log-size to show the number of bytes in
+ the log message part of the output to help qgit.
+
+ - "git svn dcommit" retains local merge information.
+
+ - "git svnimport" allows an empty string to be specified as the
+ trunk/ directory. This is necessary to suck data from a SVN
+ repository that doe not have trunk/ branches/ and tags/ organization
+ at all.
+
+ - "git config" to set values also honors type flags like --bool
+ and --int.
+
+ - core.quotepath configuration can be used to make textual git
+ output to emit most of the characters in the path literally.
+
- "git mergetool" chooses its backend more wisely, taking
notice of its environment such as use of X, Gnome/KDE, etc.
$path/$project/.git are more useful. We use $project part
in the filename, which we used to discard.
- - "git cvsimort" creates lightweight tag; there is not any
+ - "git cvsimport" creates lightweight tags; there is no
interesting information we can record in an annotated tag,
and the handcrafted ones the old code created was not
properly formed anyway.
- - "git-push" pretends that you immediately fetched back from
+ - "git push" pretends that you immediately fetched back from
the remote by updating corresponding remote tracking
branches if you have any.
- The diffstat given after a merge (or a pull) honors the
color.diff configuration.
- - "git-apply --whitespace=strip" removes blank lines added at
+ - "git commit --amend" is now compatible with various message source
+ options such as -m/-C/-c/-F.
+
+ - "git apply --whitespace=strip" removes blank lines added at
the end of the file.
- - "git-fetch" over git native protocols with -v shows connection
- status, and the IP address of the other end, to help
- diagnosing problems.
+ - "git fetch" over git native protocols with "-v" option shows
+ connection status, and the IP address of the other end, to
+ help diagnosing problems.
- We used to have core.legacyheaders configuration, when
set to false, allowed git to write loose objects in a format
- "--find-copies-harder" option to diff family can now be
spelled as "-C -C" for brevity.
- - "git-mailsplit" (hence "git-am") can read from Maildir
+ - "git mailsplit" (hence "git am") can read from Maildir
formatted mailboxes.
- - "git-cvsserver" does not barf upon seeing "cvs login"
+ - "git cvsserver" does not barf upon seeing "cvs login"
request.
- "pack-objects" honors "delta" attribute set in
.gitattributes. It does not attempt to deltify blobs that
come from paths with delta attribute set to false.
- - new-workdir script (in contrib) can now be used with a bare
- repository.
+ - "new-workdir" script (in contrib) can now be used with a
+ bare repository.
- - "git-mergetool" learned to use gvimdiff.
+ - "git mergetool" learned to use gvimdiff.
- "gitview" (in contrib) has a better blame interface.
concatenate them into a single line and treat the result as
"oneline".
+ - "git p4import" has been demoted to contrib status. For
+ a superior option, checkout the "git p4" front end to
+ "git fast-import" (also in contrib). The man page and p4
+ rpm have been removed as well.
+
+ - "git mailinfo" (hence "am") now tries to see if the message
+ is in utf-8 first, instead of assuming iso-8859-1, if
+ incoming e-mail does not say what encoding it is in.
+
* Builds
- old-style function definitions (most notably, a function
without parameter defined with "func()", not "func(void)")
have been eradicated.
+ - "git tag" and "git verify-tag" have been rewritten in C.
+
* Performance Tweaks
- - git-pack-objects avoids re-deltification cost by caching
+ - "git pack-objects" avoids re-deltification cost by caching
small enough delta results it creates while looking for the
best delta candidates.
+ - "git pack-objects" learned a new heuristcs to prefer delta
+ that is shallower in depth over the smallest delta
+ possible. This improves both overall packfile access
+ performance and packfile density.
+
- diff-delta code that is used for packing has been improved
to work better on big files.
- verifying pack contents done by "git fsck --full" got boost
by carefully choosing the order to verify objects in them.
+ - "git read-tree -m" to read into an already populated index
+ has been optimized vastly. The effect of this can be seen
+ when switching branches that have differences in only a
+ handful paths.
+
+ - "git commit paths..." has also been optimized.
