- Yes, push does not lock, but that does not mean it is not
meant for multi-user repository. It just ought to perform
correctly without using locks.
- Let's not pretend we know _the_ right way.

This adds support to http-pull for finding the list of pack files
available on the server, downloading the index files for those pack
files, and downloading pack files when they contain needed objects not
available individually. It retains the index files even if the pack
files were not needed, but downloads the list of pack files once per
run if an object is not found separately.

Just before updating a ref,
$GIT_DIR/hooks/update refname old-sha1 new-sha1
is called if executable. The hook can decline the ref to be
updated by exiting with a non-zero status, or allow it to be
updated by exiting with a zero status. The mechanism also
allows e.g sending of a mail with pushed commits on the remote
repository.
Documentation update with an example hook is included.
jc: The credits of the basic idea and initial implementation go
to Josef, but I ended up rewriting major parts of his patch, so
bugs are all mine. Also I changed the semantics for the hook
from his original version (which were post-update hook) so that
the hook can optionally decline to update the ref, and also can
be used to implement the overall cleanups. The latter was
primarily to implement a suggestion from Linus that calling
update-server-info should be made optional.

Introduce a new file $GIT_DIR/info/grafts (or $GIT_GRAFT_FILE)
which is a list of "fake commit parent records". Each line of
this file is a commit ID, followed by parent commit IDs, all
40-byte hex SHA1 separated by a single SP in between. The
records override the parent information we would normally read
from the commit objects, allowing both adding "fake" parents
(i.e. grafting), and pretending as if a commit is not a child of
some of its real parents (i.e. cauterizing).

Hmm.. Here's a tentative fix. I'm not really happy with it, and maybe
somebody else can come up with a better one. I think this one ends up
being quite a bit more expensive than the old one (it will look up _all_
common parents that have a child that isn't common, and then select the
newest one of the bunch), but I haven't really thought it through very
much.

This adds a new "git bisect" command.
- "git bisect start"
start bisection search.
- "git bisect bad <rev>"
mark some version known-bad (if no arguments, then current HEAD)
- "git bisect good <revs>..."
mark some versions known-good (if no arguments, then current HEAD)
- "git bisect reset <branch>"
done with bisection search and go back to your work (if
no arguments, then "master").
The way you use it is:
git bisect start
git bisect bad # Current version is bad
git bisect good v2.6.13-rc2 # v2.6.13-rc2 was the last version
# tested that was good
When you give at least one bad and one good versions, it will
bisect the revision tree and say something like:
Bisecting: 675 revisions left to test after this
and check out the state in the middle. Now, compile that kernel, and boot
it. Now, let's say that this booted kernel works fine, then just do
git bisect good # this one is good
which will now say
Bisecting: 337 revisions left to test after this
and you continue along, compiling that one, testing it, and depending on
whether it is good or bad, you say "git bisect good" or "git bisect bad",
and ask for the next bisection.
Until you have no more left, and you'll have been left with the first bad
kernel rev in "refs/bisect/bad".
Oh, and then after you want to reset to the original head, do a
git bisect reset
to get back to the master branch, instead of being in one of the bisection
branches ("git bisect start" will do that for you too, actually: it will
reset the bisection state, and before it does that it checks that you're
not using some old bisection branch).
Not really any harder than doing series of "quilt push" and "quilt pop",
now is it?
[jc: This patch is a rework based on what Linus posted to the
list. The changes are:
- The original introduced four separate commands, which was
three too many, so I merged them into one with subcommands.
- Since the next thing you would want to do after telling it
"bad" and "good" is always to bisect, this version does it
automatically for you.
- I think the termination condition was wrong. The original
version checked if the set of revisions reachable from next
bisection but not rechable from any of the known good ones
is empty, but if the current bisection was a bad one, this
would not terminate, so I changed it to terminate it when
the set becomes a singleton or empty.
- Removed the use of shell array variable.

Support for completely OpenSSL-less builds. FSF considers distributing GPL
binaries with OpenSSL linked in as a legal problem so this is trouble

anyway. If you

-g as well now and is not overriden if it was already declared in the

there was already a $CFLAGS environment variable, it's appended to. Some
more variables are also made overridable through the environment. Renamed

I have reviewed all occurrences of mmap() in git and fixed three types
of errors/defects:
1) The result is not checked.
2) The file descriptor is closed if mmap() succeeds, but not when it
fails.
3) Various casts applied to -1 are used instead of MAP_FAILED, which is
specifically defined to check mmap() return value.
[jc: This is a second round of Pavel's patch. He fixed up the problem
that close() potentially clobbering the errno from mmap, which
the first round had.]

Pasky and others raised many valid points on the problems
initial exclude pattern enhancement work had. Based on the
list discussion, rework the exclude logic to use "last match
determines its fate" rule, and order the list by exclude-from
(the fallback default pattern file), exclude-per-directory
(shallower to deeper, so deeper ones can override), and then
command line exclude patterns.

This corner-case was triggered by a kernel commit that was not in date
order, due to a misconfigured time zone that made the commit appear three
hours older than it was.
That caused git-rev-list to traverse the commit tree in a non-obvious
order, and made it parse several of the _parents_ of the misplaced commit
before it actually parsed the commit itself. That's fine, but it meant
that the grandparents of the commit didn't get marked uninteresting,
because they had been reached through an "interesting" branch.
The reason was that "mark_parents_uninteresting()" (which is supposed to
mark all existing parents as being uninteresting - duh) didn't actually
traverse more than one level down the parent chain.
NORMALLY this is fine, since with the date-based traversal order,
grandparents won't ever even have been looked at before their parents (so
traversing the chain down isn't needed, because the next time around when
we pick out the parent we'll mark _its_ parents uninteresting), but since
we'd gotten out of order, we'd already seen the parent and thus never got
around to mark the grandparents.
Anyway, the fix is simple. Just traverse parent chains recursively.
Normally the chain won't even exist (since the parent hasn't been parsed
yet), so this is not actually going to trigger except in this strange
corner-case.
Add a comment to the simple one-liner, since this was a bit subtle, and I
had to really think things through to understand how it could happen.

Darrin Thompson noticed when he was showing off GIT to others
that the use of filenames "a" and "b" in the tutorial example
was unnecessarily confusing, especially with our "patch -p1"
prefix a/ and b/, without giving us any patch. I was very
tempted to change them back to l/ and k/ prefixes, but decided
to restrain myself and update the tutorial instead ;-).
