GIT v1.5.5 Release Notes
========================

Updates since v1.5.4
--------------------

(subsystems)

 * Comes with git-gui 0.9.3.

(portability)

 * We shouldn't ask for BSD group ownership semantics by setting g+s bit
 on directories on older BSD systems that refuses chmod() by non root
 users. BSD semantics is the default there anyway.

 * Bunch of portability improvement patches coming from an effort to port
 to Solaris has been applied.

(performance)

 * On platforms with suboptimal qsort(3) implementation, there
 is an option to use more reasonable substitute we ship with
 our software.

 * New configuration variable "pack.packsizelimit" can be used
 in place of command line option --max-pack-size.

 * "git fetch" over the native git protocol used to make a
 connection to find out the set of current remote refs and
 another to actually download the pack data. We now use only
 one connection for these tasks.

 * "git commit" does not run lstat(2) more than necessary
 anymore.

(usability, bells and whistles)

 * Bash completion script (in contrib) are aware of more commands and
 options.

 * You can be warned when core.autocrlf conversion is applied in
 such a way that results in an irreversible conversion.

 * A catch-all "color.ui" configuration variable can be used to
 enable coloring of all color-capable commands, instead of
 individual ones such as "color.status" and "color.branch".

 * The commands refused to take absolute pathnames where they
 require pathnames relative to the work tree or the current
 subdirectory. They now can take absolute pathnames in such a
 case as long as the pathnames do not refer outside of the
 work tree. E.g. "git add $(pwd)/foo" now works.

 * Error messages used to be sent to stderr, only to get hidden,
 when $PAGER was in use. They now are sent to stdout along
 with the command output to be shown in the $PAGER.

 * A pattern "foo/" in .gitignore file now matches a directory
 "foo". Pattern "foo" also matches as before.

 * bash completion's prompt helper function can talk about
 operation in-progress (e.g. merge, rebase, etc.).

 * Configuration variables "url.<usethis>.insteadof = <otherurl>" can be
 used to tell "git-fetch" and "git-push" to use different URL than what
 is given from the command line.

 * "git add -i" behaves better even before you make an initial commit.

 * "git am" refused to run from a subdirectory without a good reason.

 * After "git apply --whitespace=fix" fixes whitespace errors in a patch,
 a line before the fix can appear as a context or preimage line in a
 later patch, causing the patch not to apply. The command now knows to
 see through whitespace fixes done to context lines to successfully
 apply such a patch series.

 * "git branch" (and "git checkout -b") to branch from a local branch can
 optionally set "branch.<name>.merge" to mark the new branch to build on
 the other local branch, when "branch.autosetupmerge" is set to
 "always". By default, this does not happen when branching from a local
 branch.

 * "git checkout" to switch to a branch that has "branch.<name>.merge" set
 (i.e. marked to build on another branch) reports how much the branch
 and the other branch diverged.

 * When "git checkout" has to update a lot of paths, it used to be silent
 for 4 seconds before it showed any progress report. It is now a bit
 more impatient and starts showing progress report early.

 * "git commit" learned a new hook "prepare-commit-msg" that can
 inspect what is going to be committed and prepare the commit
 log message template to be edited.

 * "git cvsimport" can now take more than one -M options.

 * "git describe" learned to limit the tags to be used for
 naming with --match option.

 * "git describe --contains" now barfs when the named commit
 cannot be described.

 * "git describe --exact-match" describes only commits that are tagged.

 * "git describe --long" describes a tagged commit as $tag-0-$sha1,
 instead of just showing the exact tagname.

 * "git describe" warns when using a tag whose name and path contradict
 with each other.

 * "git diff" learned "--relative" option to limit and output paths
 relative to the current directory when working in a subdirectory.

 * "git diff" learned "--dirstat" option to show birds-eye-summary of
 changes more concisely than "--diffstat".

 * "git format-patch" learned --cover-letter option to generate a cover
 letter template.

 * "git gc" learned --quiet option.

 * "git gc" now automatically prunes unreachable objects that are two
 weeks old or older.

 * "git gc --auto" can be disabled more easily by just setting gc.auto
 to zero. It also tolerates more packfiles by default.

 * "git grep" now knows "--name-only" is a synonym for the "-l" option.

 * "git help <alias>" now reports "'git <alias>' is alias to <what>",
 instead of saying "No manual entry for git-<alias>".

 * "git help" can use different backends to show manual pages and this can
 be configured using "man.viewer" configuration.

 * "gitk" does not restore window position from $HOME/.gitk anymore (it
 still restores the size).

 * "git log --grep=<what>" learned "--fixed-strings" option to look for
 <what> without treating it as a regular expression.

 * "git gui" learned an auto-spell checking.

 * "git push <somewhere> HEAD" and "git push <somewhere> +HEAD" works as
 expected; they push the current branch (and only the current branch).
 In addition, HEAD can be written as the value of "remote.<there>.push"
 configuration variable.

 * When the configuration variable "pack.threads" is set to 0, "git
 repack" auto detects the number of CPUs and uses that many threads.

 * "git send-email" learned to prompt for passwords
 interactively.

 * "git send-email" learned an easier way to suppress CC
 recipients.

 * "git stash" learned "pop" command, that applies the latest stash and
 removes it from the stash, and "drop" command to discard the named
 stash entry.

 * "git submodule" learned a new subcommand "summary" to show the
 symmetric difference between the HEAD version and the work tree version
 of the submodule commits.

 * Various "git cvsimport", "git cvsexportcommit", "git svn" and
 "git p4" improvements.

(internal)

 * Duplicated code between git-help and git-instaweb that
 launches user's preferred browser has been refactored.

 * It is now easier to write test scripts that records known
 breakages.

 * "git checkout" is rewritten in C.

 * "git remote" is rewritten in C.

 * Two conflict hunks that are separated by a very short span of common
 lines are now coalesced into one larger hunk, to make the result easier
 to read.

 * Run-command API's use of file descriptors is documented clearer and
 is more consistent now.

 * diff output can be sent to FILE * that is different from stdout. This
 will help reimplementing more things in C.

Fixes since v1.5.4
------------------

All of the fixes in v1.5.4 maintenance series are included in
this release, unless otherwise noted.

 * "git-http-push" did not allow deletion of remote ref with the usual
 "push <remote> :<branch>" syntax.

 * "git-rebase --abort" did not go back to the right location if
 "git-reset" was run during the "git-rebase" session.
