git remote: Separate usage strings for subcommands
When the usage string for a subcommand must be printed,
only print the information relevant to that command.
This commit also removes the complete options list from
the first line of the subcommand usage string. Instead,
individual options are documented in the detailed
description following the general usage line.

diffcore-rename: reduce memory footprint by freeing blob data early
After running one round of estimate_similarity(), filespecs on either
side will have populated their cnt_data fields, and we do not need
the blob text anymore. We used to retain the blob data to optimize
for smaller projects (not freeing the blob data here would mean that
the final output phase would not have to re-read it), but we are
efficient enough without such optimization for smaller projects anyway,
and freeing memory early will help larger projects.
replace: use a GIT_NO_REPLACE_OBJECTS env variable
This has the same effect as --no-replace-objects option; git ignores the
replace refs. When --no-replace-objects option is passed to git, this
environment variable is set to "1" and exported to subprocesses in order
to propagate the same setting.
It is useful for example for scripts, as the git commands used in them can
now be aware that they must not read replace refs.

setup_revisions(): do not call get_pathspec() too early
This is necessary because we will later allow pathspecs to be fed from the
standard input, and pathspecs taken from the command line (and converted
via get_pathspec() already) in revs->prune_data too early gets in the way
when we want to append from the standard input.
Move the logic to read revs from standard input that rev-list knows about
from it to revision machinery, so that all the users of setup_revisions()
can feed the list of revs from the standard input when "--stdin" is used
on the command line.
Allow some users of the revision machinery that want different semantics
from the "--stdin" option to disable it by setting an option in the
rev_info structure.
This also cleans up the kludge made to bundle.c via cut and paste.
gitweb.js: fix null object exception in initials calculation
Currently handleLine() assumes that a commit author name will always
start with a capital letter. It's possible that the author name is
user@example.com and therefore calling a match() on the name will fail
to return any matches. Subsequently joining these matches will cause an
exception. Fix by checking that we have a match before trying to join
the results into a set of initials for the author.

The t/t9700/test.pl script uses method invocation syntax when
using the Cwd module to determine the current working directory.
This fails on cygwin, since cygwin perl specifically checks for
any arguments to the cwd() function and croak()'s with the message
"Usage: Cwd::cwd()". (In perl v5.8.8 distribution, see the file
perl-5.8.8/cygwin/cygwin.c lines 139-157)
In order to avoid the problem, we replace the method invocation
syntax with a simple function call.

used by the repository at that location. However, this only affects
how the name of the helper is determined, not anything about the

Since git is not used in each and every interactive xterm, it
seems best to load completion support with cold caches and then
load each needed thing lazily. This has most of the speed
advantage of pre-generating everything at build time, without the
complication of figuring out at build time what commands will be
available at run time.
On this slow laptop, this decreases the time to load
git-completion.bash from about 500 ms to about 175 ms.

Make sure $PERL_PATH is defined when the test suite is run.
Some test scripts run Perl scripts as if they were git-* scripts, and
thus need to use the same perl that will be put in the shebang line of
git*.perl commands. $PERL_PATH therefore needs to be used instead of
a bare "perl".
The tests can fail if another perl is found in $PATH before the one
defined in $PERL_PATH.
Example test failure caused by this: the perl defined in $PERL_PATH has
Error.pm installed, and therefore the Git.pm's Makefile.PL doesn't install
the private copy. The perl from $PATH doesn't have Error.pm installed, and
all git*.perl scripts invoked during the test will fail loading Error.pm.

The "break" phase works by counting changes between two
blobs with the same path. We do this by splitting the file
into chunks (or lines for text oriented files) and then
keeping a count of chunk hashes.
The "rename" phase counts changes between blobs at two
different paths. However, it uses the exact same set of
chunk hashes (which are immutable for a given sha1).
The rename phase can therefore use the same hash data as
break. Unfortunately, we were throwing this data away after
computing it in the break phase. This patch instead attaches
it to the filespec and lets it live through the rename
phase, working under the assumption that most of the time
that breaks are being computed, renames will be too.
We only do this optimization for files which have actually
been broken, as those ones will be candidates for rename
detection (and it is a time-space tradeoff, so we don't want
to waste space keeping useless data).

As we look at each changed file and consider breaking it, we
load the blob data and make a decision about whether to
break, which is independent of any other blobs that might
have changed. However, we keep the data in memory while we
consider breaking all of the other files. Which means that
both versions of every file you are diffing are in memory at
the same time.
This patch instead frees the blob data as we finish with
each file pair, leading to much lower memory usage.

git svn: attempt to create empty dirs on clone+rebase
We parse unhandled.log files for empty_dir statements and make a

branches do not differ in empty directories.
Since this cannot affect "normal" git commands like "checkout"

working directory should use the new "git svn mkdirs" command
after switching branches.

The logic for this was originally introduced when

when "git config" was "git repo-config"), so the function is
renamed to "read_git_config" instead of "read_repo_config".
git svn: handle SVN merges from revisions past the tip of the branch
When recording the revisions that it has merged, SVN sets the top
revision to be the latest revision in the repository, which is not
necessarily a revision on the branch that is being merged from. When
it is not on the branch, git-svn fails to add the extra parent to
represent the merge because it relies on finding the commit on the
branch that corresponds to the top of the SVN merge range.
In order to correctly handle this case, we look for the maximum
revision less than or equal to the top of the SVN merge range that is
actually on the branch being merged from.
[ew: This includes the following (squashed) commit to prevent
errors during bisect:]
git-svn: add (failing) test for SVN 1.5+ merge with intervening commit
This test exposes a bug in git-svn's handling of SVN 1.5+ mergeinfo
properties. The problematic case is when there is some commit on an
unrelated branch after the last commit on the merged-from branch.
When SVN records the mergeinfo property, it records the latest
revision in the whole repository, which, in the problematic case, is
not on the branch it is merging from.
To trigger the git-svn bug, we modify t9151 to include two SVN merges,
the second of which has an intervening commit. The SVN dump was
generated using SVN 1.6.6 (on Debian squeeze amd64).

gitk: Fix "git gui blame" invocation when called from top-level directory
When run in the top-level directory of a git repository, "git
rev-parse --git-dir" doesn't return an absolute path, but merely
".git", so the selected file for "git gui blame" has a relative path.
The function make_relative then tries to make the already relative
path relative, which results in a path like "../../../../Makefile"
with as many ".." as there are elements of [pwd].
This regression was introduced by commit 9712b81 (gitk: Fix bugs in

gitk: Improve appearance of radiobuttons and checkbuttons
Commit 5497f7a23ac11f9b230892220d5ed80263eedd1f ("gitk: Add configuration

Unfortunately, tk_setPalette always chooses a dark red color for
the selectColor value if none is given explicitly, and this makes
checkbuttons and radiobuttons look rather bad.
This restores the previous appearance by specifying selectColor
explicitly. For light backgrounds we use white for selectColor, and
for dark backgrounds we use black. The formula and threshold for
distinguishing light from dark are the same as used in tk_setPalette
for choosing the foreground color.
http-backend: Fix bad treatment of uintmax_t in Content-Length
Our Content-Length needs to report an off_t, which could be larger
precision than size_t on this system (e.g. 32 bit binary built with

We also shouldn't be passing a size_t parameter to printf when
we've used PRIuMAX as the format specifier.
Fix both issues by using uintmax_t for the hdr_int() routine,
allowing strbuf's size_t to automatically upcast, and off_t to
always fit.
Also fixed the copy loop we use inside of send_local_file(), we never
actually updated the size variable so we might as well not use it.

In theory it is possible for sideband channel #2 to be delayed if
pack data is quick to come up for sideband channel #1. And because
data for channel #2 is read only 128 bytes at a time while pack data
is read 8192 bytes at a time, it is possible for many pack blocks to
be sent to the client before the progress message fifo is emptied,
making the situation even worse. This would result in totally garbled
progress display on the client's console as local progress gets mixed
with partial remote progress lines.
Let's prevent such situations by giving transmission priority to
progress messages over pack data at all times.
