This implements a new option "git gc --auto". When gc.auto is
set to a positive value, and the object database has accumulated
roughly that many number of loose objects, this runs a
lightweight version of "git gc". The primary difference from
the full "git gc" is that it does not pass "-a" option to "git
repack", which means we do not try to repack _everything_, but
only repack incrementally. We still do "git prune-packed". The
default threshold is arbitrarily set by yours truly to:
- not trigger it for fully unpacked git v0.99 history;
- do trigger it for fully unpacked git v1.0.0 history;
- not trigger it for incremental update to git v1.0.0 starting
from fully packed git v0.99 history.
This patch does not add invocation of the "auto repacking". It
is left to key Porcelain commands that could produce tons of
loose objects to add a call to "git gc --auto" after they are
done their work.

* 'master' of git://repo.or.cz/git/git-p4:
git-p4: Added support for automatically importing newly appearing perforce branches.
git-p4: Cleanup; moved the (duplicated) code for turning a branch into a git ref (for example foo -> refs/remotes/p4/<project>/foo) into a separate method.
git-p4: Cleanup; moved the code for the initial #head or revision import into a separate function, out of P4Sync.run.
git-p4: Cleanup; Turn self.revision into a function local variable (it's not used anywhere outside the function).
git-p4: Cleanup; moved the code to import a list of p4 changes using fast-import into a separate member function of P4Sync.
git-p4: Cleanup; moved the code for getting a sorted list of p4 changes for a list of given depot paths into a standalone method.
git-p4: After submission to p4 always synchronize from p4 again (into refs/remotes). Whether to rebase HEAD or not is still left as question to the end-user.
git-p4: Always call 'p4 sync ...' before submitting to Perforce.
this is still rough, hence it is disabled by default. You need to compile
with "make THREADED_DELTA_SEARCH=1 ..." at the moment.
Threading is done on different portions of the object list to be
deltified. This is currently done by spliting the list into n parts and
then a thread is spawned for each of them. A better method would consist
of spliting the list into more smaller parts and have the n threads
pick the next part available.

Kristian Høgsberg pointed out that the two file modifications
we were doing during the 'creating initial files' step are not even
used within the test suite. This was actually confusing as we do
not even need these changes for the tests to pass. All that really
matters here is the specific commit dates are used so that these
appear in the branch's reflog, and that the dates are different so
that the branch will update when asked and the reflog entry is
also updated. There is no need for the file modification.

Recently I found that doing a sequence like the following:
git-new-workdir a b
...
git-new-workdir a b
by accident will cause a (and now also b) to have an infinite cycle
in its refs directory. This is caused by git-new-workdir trying
to create the "refs" symlink over again, only during the second
time it is being created within a's refs directory and is now also
pointing back at a's refs.
This causes confusion in git as suddenly branches are named things
like "refs/refs/refs/refs/refs/refs/refs/heads/foo" instead of the
more commonly accepted "refs/heads/foo". Plenty of commands start
to see ambiguous ref names and others just take ages to compute.
git-clone has the same safety check, so git-new-workdir should
behave just like it.

When the preimage we are patching is shorter than what the patch
text expects, we tried to match the buffer contents at the
"original" line with the fragment in full, without checking we
have enough data to match in the preimage. This caused the size
of a later memmove() to wrap around and attempt to scribble
almost the entire address space. Not good.
The code that follows the part this patch touches tries to match
the fragment with line offsets. Curiously, that code does not
have the problem --- it guards against reading past the end of
the preimage.

When git-svn uses git-log to find embedded 'git-svn-id'-lines in commit
messages, it can get confused when local history contains merges with
other git-svn branches. But if --first-parent is supplied to git-log,
working_head_info() will only see 'branch-local' commits and thus the
first commit containing a 'git-svn-id' line should refer to the correct
subversion branch.

Today I found yet another way for the "Stage Hunk" and "Unstage
Hunk" context menu actions to leave the wrong state enabled in
the UI. The problem this time was that I connected the state
determination to the value of $::current_diff_side (the side the
diff is from). When the user was last looking at a diff from the
index side and unstages everything the diff panel goes empty, but
the action stayed enabled as we always assumed unstaging was a
valid action.
This change moves the logic for determining when the action is
enabled away from the individual side selection, as they really
are two unrelated concepts.

If the user tried to detach their HEAD while keeping the working
directory on the same commit we actually did not completely do
a detach operation internally. The problem was caused by git-gui
not forcing the HEAD symbolic ref to be updated to a SHA-1 hash
when we were not switching revisions. Now we update the HEAD ref
if we aren't currently detached or the hashes don't match.

Current versions of git-remote apparently are passing the -w option
to Perl as part of the shbang line:
#!/usr/bin/perl -w
this caused a problem in git-gui and gave the user a Tcl error with
the message: "git-remote not supported: #!/usr/bin/perl -w".
The fix for this is to treat the shbang line as a Tcl list and look
at the first element only for guessing the executable name. Once
we know the executable name we use the remaining elements (if any
exist) as arguments to the executable, before the script filename.

Add support for a new attribute, specfile. Files marked as being
specfiles are expanded by git-archive when they are written to an
archive. It has no effect on worktree files. The same placeholders
as those for the option --pretty=format: of git-log et al. can be

The attribute is useful for creating auto-updating specfiles. It is
limited by the underlying function format_commit_message(), though.
E.g. currently there is no placeholder for git-describe like output,
and expanded specfiles can't contain NUL bytes. That can be fixed
in format_commit_message() later and will then benefit users of

This is based on Martin Koegler's idea to keep the object that
was successfully used as the base of the delta when it is about
to fall off the edge of the window. Instead of doing so only
for the objects at the edge of the window, this makes the window
a lru eviction mechanism. If an entry is used as a base, it is
moved to the last of the queue to be evicted.
This is a quick-and-dirty implementation, as it keeps the original
implementation of the data structure used for the window. This
originally was done as an array, not as an array of pointers,
because it was meant to be used as a cyclic FIFO buffer and a
plain array avoids an extra pointer indirection, while its FIFOness
eant that we are not "moving" the entries like this patch does.

The warning message to suggest "Consider running git-status" from
"git-diff" that we experimented with during the 1.5.3 cycle turns
out to be a bad idea. It robbed cache-dirty information from people
who valued it, while still asking users to run "update-index --refresh".
It was hoped that the new behaviour would at least have some educational
value, but not showing the cache-dirty paths like before meant that the
user would not even know easily which paths were cache-dirty, and it
made the need to refresh the index look like even more unnecessary chore.
This commit reinstates the traditional behaviour, but with a twist.
By default, the empty "diff --git" output is totally squelched out
from "git diff" output. At the end of the command, it automatically
runs "update-index --refresh" as needed, without even bothering the
user. In other words, people who do not care about the cache-dirtyness
do not even have to see the warning.
The traditional behaviour to see the stat-dirty output and to bypassing
the overhead of content comparison can be specified by setting the
configuration variable diff.autorefreshindex to false.

This patch removes certain behaviour of "git tag -l foo", currently
listing every tag name having "foo" as a substring. The same
thing now could be achieved doing "git tag -l '*foo*'".
This feature was added recently when git-tag.sh got the -n option
for showing tag annotations, because that commit also replaced the
old "grep pattern" behaviour with a more preferable "shell pattern"
behaviour (although slightly modified as you can see).
Thus, the following builtin-tag.c implemented it in order to
ensure that tests were passing unchanged with both programs.
Since common "shell patterns" match names with a given substring
_only_ when * is inserted before and after (as in "*substring*"), and
the "plain" behaviour cannot be achieved easily with the current
implementation, this is mostly the right thing to do, in order to
make it more flexible and consistent.
Tests for "git tag" were also changed to reflect this.

Although dcommit could detect if the first commit in the series
would conflict with the HEAD revision in SVN, it could not
detect conflicts in further commits it made.
Now we rebase each uncommitted change after each revision is
committed to SVN to ensure that we are up-to-date. git-rebase
will bail out on conflict errors if our next change cannot be
applied and committed to SVN cleanly, preventing accidental
clobbering of changes on the SVN-side.
--no-rebase users will have trouble with this, and are thus
warned if they are committing more than one commit. Fixing this
for (hopefully uncommon) --no-rebase users would be more complex
and will probably happen at a later date.
