-GIT v1.5.3 Release Notes
-========================
-
-Updates since v1.5.2
---------------------
-
-* 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/.
-
-* Comes with git-gui 0.8.2.
-
-* Comes with updated gitk.
-
-* New commands and options.
-
- - "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" 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 daemon --base-path-relaxed" can help migrating a repository URL
- that did not use to use --base-path to use --base-path.
-
- - "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,
- core.loosecompression and pack.compression options can
- independently tweak zlib compression levels used for loose
- and packed objects.
-
- - "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
- --extended-regexp options to tweak its matching logic used
- for --grep filtering.
-
- - "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 fsck" gained --verbose option. This is really really
- verbose but it might help you identify exact commit that is
- corrupt in your repository.
-
- - "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 change
- whitespaces and indentation levels with "-w" option.
-
- - "git send-email" can be told not to thread the messages when
- sending out more than one patches.
-
- - "git send-email" can also be told how to find whom to cc the
- message to for each message via --cc-cmd.
-
- - "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.
-
- - "git -p command" now has a cousin of opposite sex, "git --no-pager
- command".
-
-* 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.
-
- - URL used for "git clone" and friends can specify nonstandard SSH port
- by using ssh://host:port/path/to/repo syntax.
-
- - "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.
- It runs "update-index --refresh" silently as needed.
-
- - "git tag -l" used to match tags by globbing its parameter as if it
- has wildcard '*' on both ends, which made "git tag -l gui" to match
- tag 'gitgui-0.7.0'; this was very annoying. You now have to add
- asterisk on the sides you want to wildcard yourself.
-
- - 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 log --name-status" does not require you to give "-r" anymore.
- As a general rule, Porcelain commands should recurse when showing
- diff.
-
- - "git format-patch --root A" can be used to format everything
- since the beginning up to A. This was supported with
- "git format-patch --root A A" for a long time, but was not
- properly documented.
-
- - "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.
-
- - "gitweb" shows merge commits a lot nicer than before. The
- default view uses more compact --cc format, while the UI
- allows to choose normal diff with any parent.
-
- - snapshot files "gitweb" creates from a repository at
- $path/$project/.git are more useful. We use $project part
- in the filename, which we used to discard.
-
- - "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
- 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 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" 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
- that mimics the format used by objects stored in packs. It
- turns out that this was not so useful. Although we will
- continue to read objects written in that format, we do not
- honor that configuration anymore and create loose objects in
- the legacy/traditional 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
- formatted mailboxes.
-
- - "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.
-
- - "git mergetool" learned to use gvimdiff.
-
- - "gitview" (in contrib) has a better blame interface.
-
- - "git log" and friends did not handle a commit log message
- that is larger than 16kB; they do now.
-
- - "--pretty=oneline" output format for "git log" and friends
- deals with "malformed" commit log messages that have more
- than one lines in the first paragraph better. We used to
- show the first line, cutting the title at mid-sentence; we
- 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
- small enough delta results it creates while looking for the
- best delta candidates.
-
- - "git pack-objects" learned a new heuristic 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.
-
- - when there are more than one pack files in the repository,
- the runtime used to try finding an object always from the
- newest packfile; it now tries the same packfile as we found
- the object requested the last time, which exploits the
- locality of references.
-
- - 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 add paths..." and "git commit paths..." has also been
- heavily optimized.
-
-Fixes since v1.5.2
-------------------
-
-All of the fixes in v1.5.2 maintenance series are included in
-this release, unless otherwise noted.
-
-* Bugfixes
-
- - "gitweb" had trouble handling non UTF-8 text with older
- Encode.pm Perl module.
-
- - "git svn" misparsed the data from the commits in the repository when
- the user had "color.diff = true" in the configuration. This has been
- fixed.
-
- - There was a case where "git svn dcommit" clobbered changes made on the
- SVN side while committing multiple changes.
-
- - "git-write-tree" had a bad interaction with racy-git avoidance and
- gitattributes mechanisms.
-
- - "git --bare command" overrode existing GIT_DIR setting and always
- made it treat the current working directory as GIT_DIR.
-
- - "git ls-files --error-unmatch" does not complain if you give the
- same path pattern twice by mistake.
-
- - "git init" autodetected core.filemode but not core.symlinks, which
- made a new directory created automatically by "git clone" cumbersome
- to use on filesystems that require these configurations to be set.
-
- - "git log" family of commands behaved differently when run as "git
- log" (no pathspec) and as "git log --" (again, no pathspec). This
- inconsistency was introduced somewhere in v1.3.0 series but now has
- been corrected.
-
- - "git rebase -m" incorrectly displayed commits that were skipped.
