Git v1.7.7 Release Notes
========================
Updates since v1.7.6
--------------------
* The scripting part of the codebase is getting prepared for i18n/l10n.
* Interix, Cygwin and Minix ports got updated.
* Various updates to git-p4 (in contrib/), fast-import, and git-svn.
* Gitweb learned to read from /etc/gitweb-common.conf when it exists,
before reading from gitweb_config.perl or from /etc/gitweb.conf
(this last one is read only when per-repository gitweb_config.perl
does not exist).
* Various codepaths that invoked zlib deflate/inflate assumed that these
functions can compress or uncompress more than 4GB data in one call on
platforms with 64-bit long, which has been corrected.
* Git now recognizes loose objects written by other implementations that
use a non-standard window size for zlib deflation (e.g. Agit running on
Android with 4kb window). We used to reject anything that was not
deflated with 32kb window.
* Interaction between the use of pager and coloring of the output has
been improved, especially when a command that is not built-in was
involved.
* "git am" learned to pass the "--exclude=<path>" option through to underlying
"git apply".
* You can now feed many empty lines before feeding an mbox file to
"git am".
* "git archive" can be told to pass the output to gzip compression and
produce "archive.tar.gz".
* "git bisect" can be used in a bare repository (provided that the test
you perform per each iteration does not need a working tree, of
course).
* The length of abbreviated object names in "git branch -v" output
now honors the core.abbrev configuration variable.
* "git check-attr" can take relative paths from the command line.
* "git check-attr" learned an "--all" option to list the attributes for a
given path.
* "git checkout" (both the code to update the files upon checking out a
different branch and the code to checkout a specific set of files) learned
to stream the data from object store when possible, without having to
read the entire contents of a file into memory first. An earlier round
of this code that is not in any released version had a large leak but
now it has been plugged.
* "git clone" can now take a "--config key=value" option to set the
repository configuration options that affect the initial checkout.
* "git commit <paths>..." now lets you feed relative pathspecs that
refer to outside your current subdirectory.
* "git diff --stat" learned a --stat-count option to limit the output of
a diffstat report.
* "git diff" learned a "--histogram" option to use a different diff
generation machinery stolen from jgit, which might give better
performance.
* "git diff" had a weird worst case behaviour that can be triggered
when comparing files with potentially many places that could match.
* "git fetch", "git push" and friends no longer show connection
errors for addresses that couldn't be connected to when at least one
address succeeds (this is arguably a regression but a deliberate
one).
* "git grep" learned "--break" and "--heading" options, to let users mimic
the output format of "ack".
* "git grep" learned a "-W" option that shows wider context using the same
logic used by "git diff" to determine the hunk header.
* Invoking the low-level "git http-fetch" without "-a" option (which
git itself never did--normal users should not have to worry about
this) is now deprecated.
* The "--decorate" option to "git log" and its family learned to
highlight grafted and replaced commits.
* "git rebase master topci" no longer spews usage hints after giving
the "fatal: no such branch: topci" error message.
* The recursive merge strategy implementation got a fairly large
fix for many corner cases that may rarely happen in real world
projects (it has been verified that none of the 16000+ merges in
the Linux kernel history back to v2.6.12 is affected with the
corner case bugs this update fixes).
* "git stash" learned an "--include-untracked option".
* "git submodule update" used to stop at the first error updating a
submodule; it now goes on to update other submodules that can be
updated, and reports the ones with errors at the end.
* "git push" can be told with the "--recurse-submodules=check" option to
refuse pushing of the supermodule, if any of its submodules'
commits hasn't been pushed out to their remotes.
* "git upload-pack" and "git receive-pack" learned to pretend that only a
subset of the refs exist in a repository. This may help a site to
put many tiny repositories into one repository (this would not be
useful for larger repositories as repacking would be problematic).
* "git verify-pack" has been rewritten to use the "index-pack" machinery
that is more efficient in reading objects in packfiles.
* test scripts for gitweb tried to run even when CGI-related perl modules
are not installed; they now exit early when the latter are unavailable.
Also contains various documentation updates and minor miscellaneous
changes.
Fixes since v1.7.6
------------------
Unless otherwise noted, all fixes in the 1.7.6.X maintenance track are
included in this release.
* "git branch -m" and "git checkout -b" incorrectly allowed the tip
of the branch that is currently checked out updated.
