[PATCH] Make -C less eager.
Like diff-tree, this patch makes -C option for diff-* brothers
to use only pre-image of modified files as rename/copy detection
by default. Give --find-copies-harder to use unmodified files
to find copies from as well.
This also fixes "diff-files -C" problem earlier noticed by
Linus. It was feeding the null sha1 even when the file in the
work tree was known to match what is in the index file. This
resulted in diff-files showing everything in the project.

[PATCH] read-tree: fix too strong index requirement #5ALT
This fixes too strong index requirement 3-way merge enforces in
one case: the same file is added in both branches.
In this case, the original code insisted that if the index file
has that path, it must match our branch and be up-to-date.
However in this particular case, it only has to match it, and
can be dirty. We just need to make sure that we keep the
work-tree copy instead of checking out the merge result.
The resolution of such a path, however, cannot be left to
outside script, because we will not keep the original stage0
entries for unmerged paths when read-tree finishes, and at that
point, the knowledge of "if we resolve it to match the new file
added in both branches, the merge succeeds and the work tree
would not lose information, but we should _not_ update the work
tree from the resulting index file" is lost. For this reason,
the now code needs to resolve this case (#5ALT) internally.
This affects some existing tests in the test suite, but all in
positive ways. In t1000 (3-way test), this #5ALT case now gets
one stage0 entry, instead of an identical stage2 and stage3
entry pair, for such a path, and one test that checked for merge
failure (because the test assumed the "stricter-than-necessary"
behaviour) does not have to fail anymore. In t1005 (emu23
test), two tests that involves a case where the work tree
already had a change introduced in the upstream (aka "merged
head"), the merge succeeds instead of failing.

This new flag causes two-way fast forward to internally use the

The new test t1005 is parallel to the existing t1001 "pure

These failures are due to three-way merge enforcing too strict

will be addressed by later patches.
Without even changing three-way mechanism, the --emu23 two-way

Fix up git-merge-one-file-script
Junio points out that we may need to create the path leading
up the the file we merge.
And we need to be more careful with the "exec"s we've done
to exit on success - only do the on the last command in the
pipeline, not the first one ;)

Leave merge failures in the filesystem
This changes how we handle merges: if a automated merge
fails, we will leave the index as a clean entry pointing
to the original branch, and leave the actual file _dirty_
the way the "merge" program left it.
You can then just do "git-diff-files -p" to see what the
merge conflicts did, fix them up, and commit the end result.
NOTE NOTE NOTE! Do _not_ use "git commit" to commit such
a merge. It won't set the parents right. I'll need to fix
that. In the meantime, you'd need to merge using
git-commit-tree $(git-write) -p HEAD -p MERGE_HEAD

[PATCH] three --merge-order bug fixes
This patch fixes three bugs in --merge-order support
* mark_ancestors_uninteresting was unnecessarily exponential which
caused a problem when a commit with no parents was merged near the
head of something like the linux kernel
* removed a spurious statement from find_base which wasn't
apparently causing problems now, but wasn't correct either.
* removed an unnecessarily strict check from find_base_for_list
that causes a problem if git-rev-list commit ^parent-of-commit
is specified.
* added some unit tests which were accidentally omitted from
original merge-order patch
The fix to mark_ancestors_uninteresting isn't an optimal fix - a full
graph scan will still be performed in this case even though it is
not strictly required. However, a full graph scan is linear
and still no worse than git-rev-list HEAD which runs in less than 2
seconds on a warm cache.

[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
337cb3fb8da45f10fe9a0c3cf571600f55ead2ce.
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.
