* New commands and options.
- - "git log" and friends take --reverse. This makes output
- that typically goes reverse order in chronological order.
- "git shortlog" usually lists commits in chronological order,
- but with "--reverse", they are shown in reverse
- chronological order.
+ - "git log" and friends take --reverse, which instructs them
+ to give their output in the order opposite from their usual.
+ They typically output from new to old, but with this option
+ their output would read from old to new. "git shortlog"
+ usually lists older commits first, but with this option,
+ they are shown from new to old.
+
+ - "git log --pretty=format:<string>" to allow more flexible
+ custom log output.
- "git diff" learned --ignore-space-at-eol. This is a weaker
form of --ignore-space-change.
+ - "git diff --no-index pathA pathB" can be used as diff
+ replacement with git specific enhancements.
+
+ - "git diff --no-index" can read from '-' (standard input).
+
+ - "git diff" also learned --exit-code to exit with non-zero
+ status when it found differences. In the future we might
+ want to make this the default but that would be a rather big
+ backward incompatible change; it will stay as an option for
+ now.
+
+ - "git diff --quiet" is --exit-code with output turned off,
+ meant for scripted use to quickly determine if there is any
+ tree-level difference.
+
+ - Textual patch generation with "git diff" without -w/-b
+ option has been significantly optimized. "git blame" got
+ faster because of the same change.
+
+ - "git log" and "git rev-list" has been optimized
+ significantly when they are used with pathspecs.
+
+ - "git branch --track" can be used to set up configuration
+ variables to help it easier to base your work on branches
+ you track from a remote site.
+
+ - "git format-patch --attach" now emits attachments. Use
+ --inline to get an inlined multipart/mixed.
+
- "git name-rev" learned --refs=<pattern>, to limit the tags
used for naming the given revisions only to the ones
matching the given pattern.
-* Updated behaviour of existing commands.
+ - "git remote update" is to run "git fetch" for defined remotes
+ to update tracking branches.
+
+ - "git cvsimport" can now take '-d' to talk with a CVS
+ repository different from what are recorded in CVS/Root
+ (overriding it with environment CVSROOT does not work).
+
+ - "git bundle" can help sneaker-netting your changes between
+ repositories.
+
+ - "git mergetool" can help 3-way file-level conflict
+ resolution with your favorite graphical merge tools.
+
+ - A new configuration "core.symlinks" can be used to disable
+ symlinks on filesystems that do not support them; they are
+ checked out as regular files instead.
+
+ - You can name a commit object with its first line of the
+ message. The syntax to use is ':/message text'. E.g.
+
+ $ git show ":/object name: introduce ':/<oneline prefix>' notation"
+
+ means the same thing as:
+
+ $ git show 28a4d940443806412effa246ecc7768a21553ec7
+
+ - "git bisect" learned a new command "run" that takes a script
+ to run after each revision is checked out to determine if it
+ is good or bad, to automate the bisection process.
+
+ - "git log" family learned a new traversal option --first-parent,
+ which does what the name suggests.
+
+
+* Updated behavior of existing commands.
+
+ - "git-merge-recursive" used to barf when there are more than
+ one common ancestors for the merge, and merging them had a
+ rename/rename conflict. This has been fixed.
+
+ - "git fsck" does not barf on corrupt loose objects.
+
+ - "git rm" does not remove newly added files without -f.
+
+ - "git archimport" allows remapping when coming up with git
+ branch names from arch names.
+
+ - git-svn got almost a rewrite.
+
+ - core.autocrlf configuration, when set to 'true', makes git
+ to convert CRLF at the end of lines in text files to LF when
+ reading from the filesystem, and convert in reverse when
+ writing to the filesystem. The variable can be set to
+ 'input', in which case the conversion happens only while
+ reading from the filesystem but files are written out with
+ LF at the end of lines. Currently, which paths to consider
+ 'text' (i.e. be subjected to the autocrlf mechanism) is
+ decided purely based on the contents, but the plan is to
+ allow users to explicitly override this heuristic based on
+ paths.
+
+ - The behavior of 'git-apply', when run in a subdirectory,
+ without --index nor --cached were inconsistent with that of
+ the command with these options. This was fixed to match the
+ behavior with --index. A patch that is meant to be applied
+ with -p1 from the toplevel of the project tree can be
+ applied with any custom -p<n> option. A patch that is not
+ relative to the toplevel needs to be applied with -p<n>
+ option with or without --index (or --cached).
- "git diff" outputs a trailing HT when pathnames have embedded
SP on +++/--- header lines, in order to help "GNU patch" to
parse its output. "git apply" was already updated to accept
this modified output format since ce74618d (Sep 22, 2006).
+ - "git cvsserver" runs hooks/update and honors its exit status.
+
+ - "git cvsserver" can be told to send everything with -kb.
+
+ - "git diff --check" also honors the --color output option.
+
+ - "git name-rev" used to stress the fact that a ref is a tag too
+ much, by saying something like "v1.2.3^0~22". It now says
+ "v1.2.3~22" in such a case (it still says "v1.2.3^0" if it does
+ not talk about an ancestor of the commit that is tagged, which
+ makes sense).
+
+ - "git rev-list --boundary" now shows boundary markers for the
+ commits omitted by --max-age and --max-count condition.
+
+ - The configuration mechanism now reads $(prefix)/etc/gitconfig.
+
+ - "git apply --verbose" shows what preimage lines were wanted
+ when it couldn't find them.
+
+ - "git status" in a read-only repository got a bit saner.
+
+ - "git fetch" (hence "git clone" and "git pull") are less
+ noisy when the output does not go to tty.
+
+ - "git fetch" between repositories with many refs were slow
+ even when there are not many changes that needed
+ transferring. This has been sped up by partially rewriting
+ the heaviest parts in C.
+
+ - "git mailinfo" which splits an e-mail into a patch and the
+ meta-information was rewritten, thanks to Don Zickus. It
+ handles nested multipart better. The command was broken for
+ a brief period on 'master' branch since 1.5.0 but the
+ breakage is fixed now.
+
+ - send-email learned configurable bcc and chain-reply-to.
+
+ - "git remote show $remote" also talks about branches that
+ would be pushed if you run "git push remote".
+
+ - Using objects from packs is now seriously optimized by clever
+ use of a cache. This should be most noticeable in git-log
+ family of commands that involve reading many tree objects.
+ In addition, traversing revisions while filtering changes
+ with pathspecs is made faster by terminating the comparison
+ between the trees as early as possible.
+
+
* Hooks
- - The sample update hook to show how to send out notification
- e-mail was updated to show only new commits that appeared in
- the repository. Earlier, it showed new commits that appeared
- on the branch.
+ - The part to send out notification e-mails was removed from
+ the sample update hook, as it was not an appropriate place
+ to do so. The proper place to do this is the new post-receive
+ hook. An example hook has been added to contrib/hooks/.
+
+
+* Others
+
+ - git-revert, git-gc and git-cherry-pick are now built-ins.
+
+Fixes since v1.5.0
+------------------
+
+These are all in v1.5.0.x series.
+
+* Documentation updates
+
+ - Clarifications and corrections to 1.5.0 release notes.
+
+ - The main documentation did not link to git-remote documentation.
+
+ - Clarified introductory text of git-rebase documentation.
+
+ - Converted remaining mentions of update-index on Porcelain
+ documents to git-add/git-rm.
+
+ - Some i18n.* configuration variables were incorrectly
+ described as core.*; fixed.
+
+ - added and clarified core.bare, core.legacyheaders configurations.
+
+ - updated "git-clone --depth" documentation.
+
+ - user-manual updates.
+
+ - Options to 'git remote add' were described insufficiently.
+
+ - Configuration format.suffix was not documented.
+
+ - Other formatting and spelling fixes.
+
+ - user-manual has better cross references.
+
+ - gitweb installation/deployment procedure is now documented.
+
+
+* Bugfixes
+
+ - git-upload-pack closes unused pipe ends; earlier this caused
+ many zombies to hang around.
+
+ - git-rerere was recording the contents of earlier hunks
+ duplicated in later hunks. This prevented resolving the same
+ conflict when performing the same merge the other way around.
+
+ - git-add and git-update-index on a filesystem on which
+ executable bits are unreliable incorrectly reused st_mode
+ bits even when the path changed between symlink and regular
+ file.
+
+ - git-daemon marks the listening sockets with FD_CLOEXEC so
+ that it won't be leaked into the children.
+
+ - segfault from git-blame when the mandatory pathname
+ parameter was missing was fixed; usage() message is given
+ instead.
+
+ - git-rev-list did not read $GIT_DIR/config file, which means
+ that did not honor i18n.logoutputencoding correctly.
+
+ - Automated merge conflict handling when changes to symbolic
+ links conflicted were completely broken. The merge-resolve
+ strategy created a regular file with conflict markers in it
+ in place of the symbolic link. The default strategy,
+ merge-recursive was even more broken. It removed the path
+ that was pointed at by the symbolic link. Both of these
+ problems have been fixed.
+
+ - 'git diff maint master next' did not correctly give combined
+ diff across three trees.
+
+ - 'git fast-import' portability fix for Solaris.
+
+ - 'git show-ref --verify' without arguments did not error out
+ but segfaulted.
+
+ - 'git diff :tracked-file `pwd`/an-untracked-file' gave an extra
+ slashes after a/ and b/.
+
+ - 'git format-patch' produced too long filenames if the commit
+ message had too long line at the beginning.
+
+ - Running 'make all' and then without changing anything
+ running 'make install' still rebuilt some files. This
+ was inconvenient when building as yourself and then
+ installing as root (especially problematic when the source
+ directory is on NFS and root is mapped to nobody).
+
+ - 'git-rerere' failed to deal with two unconflicted paths that
+ sorted next to each other.
+
+ - 'git-rerere' attempted to open(2) a symlink and failed if
+ there was a conflict. Since a conflicting change to a
+ symlink would not benefit from rerere anyway, the command
+ now ignores conflicting changes to symlinks.
+
+ - 'git-repack' did not like to pass more than 64 arguments
+ internally to underlying 'rev-list' logic, which made it
+ impossible to repack after accumulating many (small) packs
+ in the repository.
+
+ - 'git-diff' to review the combined diff during a conflicted
+ merge were not reading the working tree version correctly
+ when changes to a symbolic link conflicted. It should have
+ read the data using readlink(2) but read from the regular
+ file the symbolic link pointed at.
+
+ - 'git-remote' did not like period in a remote's name.
+
+ - 'git.el' honors the commit coding system from the configuration.
+
+ - 'blameview' in contrib/ correctly digs deeper when a line is
+ clicked.
+
+ - 'http-push' correctly makes sure the remote side has leading
+ path. Earlier it started in the middle of the path, and
+ incorrectly.
+
+ - 'git-merge' did not exit with non-zero status when the
+ working tree was dirty and cannot fast forward. It does
+ now.
+
+ - 'cvsexportcommit' does not lose yet-to-be-used message file.
+
+ - int-vs-size_t typefix when running combined diff on files
+ over 2GB long.
+
+ - 'git apply --whitespace=strip' should not touch unmodified
+ lines.
+
+ - 'git-mailinfo' choke when a logical header line was too long.
+
+ - 'git show A..B' did not error out. Negative ref ("not A" in
+ this example) does not make sense for the purpose of the
+ command, so now it errors out.
+
+ - 'git fmt-merge-msg --file' without file parameter did not
+ correctly error out.
+
+ - 'git archimport' barfed upon encountering a commit without
+ summary.
+
+ - 'git index-pack' did not protect itself from getting a short
+ read out of pread(2).
+
+ - 'git http-push' had a few buffer overruns.
+
+ - Build dependency fixes to rebuild fetch.o when other headers
+ change.
+
+ - git.el does not add duplicate sign-off lines.
+
+ - git-commit shows the full stat of the resulting commit, not
+ just about the files in the current directory, when run from
+ a subdirectory.
+
+ - "git-checkout -m '@{8 hours ago}'" had a funny failure from
+ eval; fixed.
+
+ - git-merge (hence git-pull) did not refuse fast-forwarding
+ when the working tree had local changes that would have
+ conflicted with it.
+
+ - a handful small fixes to gitweb.
+
+ - build procedure for user-manual is fixed not to require locally
+ installed stylesheets.
+
+ - "git commit $paths" on paths whose earlier contents were
+ already updated in the index were failing out.
+
+
+* Tweaks
---
-exec >/var/tmp/1
-O=v1.5.0-49-g69bc0e2
-echo O=`git describe master`
-git shortlog --no-merges $O..master ^maint
+ - sliding mmap() inefficiently mmaped the same region of a
+ packfile with an access pattern that used objects in the
+ reverse order. This has been made more efficient.
