An earlier commit 8098a178b2
accidentally lost race protection from git-commit command.
This commit reinstates it. When something else updates HEAD
pointer while you were editing your commit message, the command
would notice and abort the commit.

The new flag is used to amend the tip of the current branch. Prepare
the tree object you would want to replace the latest commit as usual
(this includes the usual -i/-o and explicit paths), and the commit log
editor is seeded with the commit message from the tip of the current
branch. The commit you create replaces the current tip -- if it was a
merge, it will have the parents of the current tip as parents -- so the
current top commit is discarded.
It is a rough equivalent for:
$ git reset --soft HEAD^
$ ... do something else to come up with the right tree ...
$ git commit -c ORIG_HEAD
but can be used to amend a merge commit.

This adds a new flag, --topics, to help managing topic
branches. When you have topic branches forked some time ago
from your primary line of development, show-branch would show
many "uninteresting" things that happend on the primary line of
development when trying to see what are still not merged from
the topic branches.
With this flag, the first ref given to show-branch is taken as
the primary branch, and the rest are taken as the topic
branches. Output from the command is modified so that commits
only on the primary branch are not shown. In other words,
$ git show-branch --topics master topic1 topic2 ...
shows an (almost) equivalent of
$ git rev-list ^master topic1 topic2 ...
The major differences are that (1) you can tell which commits
are on which branch, and (2) the commit at the fork point is
shown.

Now this is really a corner case, but if you have the git source
tree from somewhere other than the official tarball, you do not
have version file. And if git-describe does not work for you
(maybe you do not have git yet), we spilled an error message
from "cat version".

Here is an updated version of git-blame. The main changes compared to
the first version are:
* Use the new revision.h interface to do the revision walking
* Do the right thing in a lot of more cases than before. In particular
parallel development tracks are hopefully handled sanely.
* Lots of clean-up
It still won't follow file renames though.
There are still some differences in the output between git-blame and
git-annotate. For example, in 'Makefile' git-blame assigns lines
354-358 to 455a7f3275 and git-annotate
assigns the same lines to 79a9d8ea0d.
I think git-blame is correct in this case. This patterns occur in
several other places, git-annotate seems to sometimes assign lines to
merge commits when the lines actually changed in some other commit
which precedes the merge.
[jc: I have conned Ryan into doing test cases, so that it would
help development and fixes on both implementations. Let the
battle begin! ;-) ]

* master:
contrib/git-svn: use refs/remotes/git-svn instead of git-svn-HEAD
Merge branch 'maint'
read-tree --aggressive: remove deleted entry from the working tree.
Merge branch 'jc/tag'
Merge part of 'jc/diff'
After reading a lengthy discussion on the list, I've come to the
conclusion that creating a 'remotes' directory in refs isn't
such a bad idea.
You can still branch from it by specifying remotes/git-svn (not
needing the leading 'refs/'), and the documentation has been
updated to reflect that.
The 'git-svn' part of the ref can of course be set to whatever
you want by using the GIT_SVN_ID environment variable, as
before.
I'm using refs/remotes/git-svn, and not going with something
like refs/remotes/git-svn/HEAD as it's redundant for Subversion
where there's zero distinction between branches and directories.
Run git-svn rebuild --upgrade to upgrade your repository to use
the new head. git-svn-HEAD must be manually deleted for safety
reasons.
Side note: if you ever (and I hope you never) want to run
git-update-refs on a 'remotes/' ref, make sure you have the
'refs/' prefix as you don't want to be clobbering your
'remotes/' in $GIT_DIR (where remote URLs are stored).

* np/delta:
diff-delta: allow reusing of the reference buffer index
diff-delta: bound hash list length to avoid O(m*n) behavior

annotate: fix -S parameter to take a string
annotate: Add a basic set of test cases.
annotate: handle \No newline at end of file.
gitview: Use horizontal scroll bar in the tree view
When a reference buffer is used multiple times then its index can be
computed only once and reused multiple times. This patch adds an extra
pointer to a pointer argument (from_index) to diff_delta() for this.
If from_index is NULL then everything is like before.
If from_index is non NULL and *from_index is NULL then the index is
created and its location stored to *from_index. In this case the caller
has the responsibility to free the memory pointed to by *from_index.
If from_index and *from_index are non NULL then the index is reused as
is.
This currently saves about 10% of CPU time to repack the git archive.

The diff-delta code can exhibit O(m*n) behavior with some patological
data set where most hash entries end up in the same hash bucket.
The latest code rework reduced the block size making it particularly
vulnerable to this issue, but the issue was always there and can be
triggered regardless of the block size.
This patch does two things:
1) the hashing has been reworked to offer a better distribution to
atenuate the problem a bit, and
2) a limit is imposed to the number of entries that can exist in the
same hash bucket.
Because of the above the code is a bit more expensive on average, but
the problematic samples used to diagnoze the issue are now orders of
magnitude less expensive to process with only a slight loss in
compression.

Indexing based on adler32 has a match precision based on the block size
(currently 16). Lowering the block size would produce smaller deltas
but the indexing memory and computing cost increases significantly.
For optimal delta result the indexing block size should be 3 with an
increment of 1 (instead of 16 and 16). With such low params the adler32
becomes a clear overhead increasing the time for git-repack by a factor
of 3. And with such small blocks the adler 32 is not very useful as the
whole of the block bits can be used directly.
This patch replaces the adler32 with an open coded index value based on
3 characters directly. This gives sufficient bits for hashing and
allows for optimal delta with reasonable CPU cycles.
The resulting packs are 6% smaller on average. The increase in CPU time
is about 25%. But this cost is now hidden by the delta reuse patch
while the saving on data transfers is always there.

Initial checkouts were failing to create Entries files under Eclipse.
Eclipse was waiting for two non-standard directory-resets to prepare for a new

This patch is tricky, because the same directory resets tend to confuse other

$ git-cat-file -p v1.2.3

$ git-verify-tag --verbose v1.2.3

The war on trailing whitespace
Moving a directory ending in a slash was not working as the
destination was not calculated correctly.
E.g. in the git repo,
git-mv t/ Documentation
gave the error
Error: destination 'Documentation' already exists
To get rid of this problem, strip trailing slashes from all arguments.
The comment in cg-mv made me curious about this issue; Pasky, thanks!
As result, the workaround in cg-mv is not needed any more.
Also, another bug was shown by cg-mv. When moving files outside of
a subdirectory, it typically calls git-mv with something like
git-mv Documentation/git.txt Documentation/../git-mv.txt
which triggers the following error from git-update-index:
Ignoring path Documentation/../git-mv.txt
The result is a moved file, removed from git revisioning, but not
added again. To fix this, the paths have to be normalized not have ".."
in the middle. This was already done in git-mv, but only for
a better visual appearance :(
