Cauterize dropped or duplicate bits from next.

I am very sorry to do this, but without this funky octopus, "git
log --no-merges master..next" will show commits already merged
into "master" forever.

There are some commits on the next branch (which is never to be
rewound) that are reverts of other commits on the next branch.
They are to revert the finer grained delta experiments that
turned out to have undesirable performance effects.  Also there
are some other commits that were first done as a merge into
"next" (a pull request based on next) and then cherry picked
into master.  Since they are not going to be merged into
"master" ever, they will stay forever in "log master..next".

Yuck.

So this commit records the fact that the commits currently shown
by "git log --no-merges master..next" to be merged into "master"
are already in the master, either because they really are (in
the case of git-cvsserver bits, which needed cherry-picking into
"master"), or because they are fully reverted in "next" (in the
case of finer-grained delta bits).

Here is the way I made this commit:

 (1) Inspect "gitk --no-merges --parents master..next"

     This shows what git thinks are missing from master.  It
     shows chain of commits that are already merged and chain of
     commits whose net effect should amount to a no-op.

     Look at each commits and make sure they are either unwanted
     or already merged by cherry-picking.

 (2) Record the tip of branches that I do not want.  In this
     case, the following were unwanted:

     cfcbd3427e67056a00ec832645b057eaf33888d9 cvsserver
     c436eb8cf1efa3fe2c70100ae0cbc48f0feaf5af diff-delta

     2b8d9347aa1a11f1ac13591f89ca9f984d467c77 diff-delta

 (3) Shorten the list by finding independent ones from the
     above.

     $ git show-branch --independent $the $above $tips

     cfcbd3427e67056a00ec832645b057eaf33888d9
     c436eb8cf1efa3fe2c70100ae0cbc48f0feaf5af

 (4) Checkout "master" and cauterize them with "ours" strategy:

     $ git merge -s ours "`cat $this-file`" HEAD cfcbd3 c436eb

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.

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 455a7f3275d264f6e66045b92c83747ec461dda5 and git-annotate
assigns the same lines to 79a9d8ea0d88a3667ad19be8e705405ab5d896f1.

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.

contrib/git-svn: use refs/remotes/git-svn instead of git-svn-HEAD

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).

diff-delta: allow reusing of the reference buffer index

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.

diff-delta: bound hash list length to avoid O(m*n) behavior

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.

Nicolas Pitre [Wed, 22 Feb 2006 01:45:36 +0000 (20:45 -0500)]
diff-delta: produce optimal pack data

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.
