809809bb75 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.

6476b38b1f 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.

7a0d61bb45 describe: do not use unannotated tag even if exact match
4d23660 (describe: when failing, tell the user about options that
work, 2009-10-28) forgot to update the shortcut path where the code
detected and used a possible exact match.  This means that an
unannotated tag on HEAD would be used by 'git describe'.

Guard this code path against the new circumstances, where unannotated
tags can be present in ->util even if we're not actually planning to
use them.

While there, also add some tests for --all.

8b3dce5650 Teach --stdin option to "log" family
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.

e42a05f75c 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.

81f40262a4 t9700-perl-git.sh: Fix a test failure on Cygwin
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.

c578f51d52 Add a config option for remotes to specify a foreign vcs
If this is set, the url is not required, and the transport always uses
a helper named "git-remote-<value>".

It is a separate configuration option in order to allow a sensible
configuration for foreign systems which either have no meaningful urls
for repositories or which require urls that do not specify the system
used by the repository at that location. However, this only affects
how the name of the helper is determined, not anything about the
interaction with the helper, and the contruction is such that, if the
foreign scm does happen to use a co-named url method, a url with that
method may be used directly.

For fetch and ls-remote, which use the first url of a remote, have
transport_get() determine this by passing a remote and passing NULL
for the url. For push, which uses every url of a remote, use each url
in turn if there are any, and use NULL if there are none.

This will allow the transport code to do something different if the
location is not specified with a url.

Also, have the message for a fetch say "foreign" if there is no url.

eaa4e6ee2a Speed up bash completion loading
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.

be38ca3d19 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.

8282de94bc diffcore-break: save cnt_data for other phases
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).

f4f19fb634 diffcore-break: free filespec data as we go
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.
