7a59013290 GIT 0.99.4 (release candidate)
This is my first attempt to adjust Debian and RPM to pass
prefix, to prepare the 0.99.4 release.

It updates debian/rules and git-core.spec.in to properly pass
prefix when building binary packages.  It also updates
debian/changelog to make the resulting binary package name
0.99.4; this is not needed on the RPM side (it takes the version

b1bf95bba2 [PATCH] Added hook in git-receive-pack
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.

8cc6a08319 [PATCH] Making it easier to find which change introduced a bug
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.

399144f21c Add a "git rename" to help with - surprise surprise - renames
It's stupid.  We'd want to rename directories too, but this doesn't do
that yet - easy enough to do per se, we just need to carefully list all
the pathnames that got moved (and remember to ignore the files that
weren't tracked but are in the subdirectory that got moved).

Doing the directory case will require a bit more scripting.. Something like

	oldfiles=($(git-ls-files | grep '^$src'))
	newfiles=($(git-ls-files | sed ':^$src: s:^$src:$dst:'))
	mv $src $dst && git-update-cache --add --remove -- "${oldfiles[@]}" "${newfiles[@]}"

might do it, except it needs to be done right, and carefully.  Methinks
perl is probably better at this. Hint hint..

8f3f9b09dc [PATCH] Add update-server-info.
The git-update-server-info command prepares informational files
to help clients discover the contents of a repository, and pull
from it via a dumb transport protocols.  Currently, the
following files are produced.

 - The $repo/info/refs file lists the name of heads and tags
   available in the $repo/refs/ directory, along with their
   SHA1.  This can be used by git-ls-remote command running on
   the client side.

 - The $repo/info/rev-cache file describes the commit ancestry
   reachable from references in the $repo/refs/ directory.  This
   file is in an append-only binary format to make the server
   side friendly to rsync mirroring scheme, and can be read by
   git-show-rev-cache command.

 - The $repo/objects/info/pack file lists the name of the packs
   available, the interdependencies among them, and the head
   commits and tags contained in them.  Along with the other two
   files, this is designed to help clients to make smart pull
   decisions.

The git-receive-pack command is changed to invoke it at the end,
so just after a push to a public repository finishes via "git
push", the server info is automatically updated.

In addition, building of the rev-cache file can be done by a
standalone git-build-rev-cache command separately.

78d9d41412 Ahh, the heady days of 0.99 patchfiles
Now, not all projects can be as refined as Linux.  Before the final 1.0

through subreleases 'a' through 'z'. Now _that_ is a release process.

Not to mention the odd-ball releases, like 0.96c+

Sadly, in this day and age of RPM's etc, we have silly limitations, and
I cannot call this release '0.99pl5a or some such awe-inspiring name
just because "rpmbuild" is such a party pooper.  So it's just 0.99.1.

Nico pointed out that having verify_pack.c and verify-pack.c was
confusing.  Rename verify_pack.c to pack-check.c as suggested,
and enhances the verification done quite a bit.

 - Built-in sha1_file unpacking knows that a base object of a
   deltified object _must_ be in the same pack, and takes
   advantage of that fact.

 - Earlier verify-pack command only checked the SHA1 sum for the
   entire pack file and did not look into its contents.  It now
   checks everything idx file claims to have unpacks correctly.

 - It now has a hook to give more detailed information for
   objects contained in the pack under -v flag.

f9253394a2 [PATCH] Add git-verify-pack command.
Given a list of <pack>.idx files, this command validates the
index file and the corresponding .pack file for consistency.

This patch also uses the same validation mechanism in fsck-cache
when the --full flag is used.

During normal operation, sha1_file.c verifies that a given .idx
file matches the .pack file by comparing the SHA1 checksum
stored in .idx file and .pack file as a minimum sanity check.
We may further want to check the pack signature and version when
we map the pack, but that would be a separate patch.

Earlier, errors to map a pack file was not flagged fatal but led
to a random fatal error later.  This version explicitly die()s
when such an error is detected.

c323ac7d9c git-pack-objects: create a packed object representation.
This is kind of like a tar-ball for a set of objects, ready to be
shipped off to another end.  Alternatively, you could use is as a packed
representation of the object database directly, if you changed
"read_sha1_file()" to read these kinds of packs.

The latter is partiularly useful to generate a "packed history", ie you
could pack up your old history efficiently, but still have it available
(at a performance hit, of course).

I haven't actually written an unpacker yet, so the end result has not
been verified in any way yet.  I obviously always write bug-free code,
so it just has to work, no?

then allow you to use arguments like "v2.6.12-rc5.." or similar
human-readable ranges.

It's really quite stupid: "a..b" will be converted into "a" and "^b" if
"a" and "b" are valid object pointers.  And the "--default" case will be
used if nothing but flags have been seen, so that you can default to a
certain argument if there are no other ranges.

a3437b8c26 [PATCH] Modify git-rev-list to linearise the commit history in merge order.
This patch linearises the GIT commit history graph into merge order
which is defined by invariants specified in Documentation/git-rev-list.txt.

The linearisation produced by this patch is superior in an objective sense
to that produced by the existing git-rev-list implementation in that
the linearisation produced is guaranteed to have the minimum number of
discontinuities, where a discontinuity is defined as an adjacent pair of
commits in the output list which are not related in a direct child-parent
relationship.

With this patch a graph like this:

	a4 ---
	| \   \
	|  b4 |
	|/ |  |
	a3 |  |
	|  |  |
	a2 |  |
	|  |  c3
	|  |  |
	|  |  c2
	|  b3 |
	|  | /|
	|  b2 |
	|  |  c1
	|  | /
	|  b1
	a1 |
	|  |
	a0 |
	| /
	root

Sorts like this:

	= a4
	| c3
	| c2
	| c1
	^ b4
	| b3
	| b2
	| b1
	^ a3
	| a2
	| a1
	| a0
	= root

Instead of this:

	= a4
	| c3
	^ b4
	| a3
	^ c2
	^ b3
	^ a2
	^ b2
	^ c1
	^ a1
	^ b1
	^ a0
	= root

A test script, t/t6000-rev-list.sh, includes a test which demonstrates
that the linearisation produced by --merge-order has less discontinuities
than the linearisation produced by git-rev-list without the --merge-order
flag specified. To see this, do the following:

	cd t
	./t6000-rev-list.sh
	cd trash
	cat actual-default-order
	cat actual-merge-order

The existing behaviour of git-rev-list is preserved, by default. To obtain
the modified behaviour, specify --merge-order or --merge-order --show-breaks
on the command line.

This version of the patch has been tested on the git repository and also on the linux-2.6
repository and has reasonable performance on both - ~50-100% slower than the original algorithm.

This version of the patch has incorporated a functional equivalent of the Linus' output limiting
algorithm into the merge-order algorithm itself. This operates per the notes associated
with Linus' commit 337cb3fb8d.

This version has incorporated Linus' feedback regarding proposed changes to rev-list.c.
(see: [PATCH] Factor out filtering in rev-list.c)

This version has improved the way sort_first_epoch marks commits as uninteresting.

For more details about this change, refer to Documentation/git-rev-list.txt
and http://blackcubes.dyndns.org/epoch/.
