git-apply: implement "diffstat" output
Hey, it's almost free by now, and it's a good way to see that

git-apply: parse the whole list of patches into memory first
Make it a clear two-phase thing: first a read-only parse of
the patch itself (which is independent of any current index
information), and then the second phase actually uses the patch.
The second phase might not be a real apply, it could be just a
diffstat, for example. Which is trivial to do once the patch is
parsed.

[PATCH] Test case portability fix.
This is the remainder of testcase fix by Mark Allen to make them
work on his Darwin box. I was using "xargs -r" (GNU) where it
was not needed, sed -ne '/^\(author\|committer\)/s|>.*|>|p'
where some sed does not know what to do with '\|', and also
"cmp - file" to compare standard input with a file, which his
cmp does not support.

git-rev-list: add "end" commit and "--header" flag
The "end" commit is just faking it right now, it's sorting things
purely by date, so this is _not_ a reachability analysis. Some day.
The "--header" flag causes the commit message to be printed out,
with a NUL character separator after it for parseability. This
allows you to do things like use "grep -z" to grep for certain
authors etc.

[PATCH] Redo rename/copy detection logic.
Earlier implementation had a major screw-up in the memory
management area. Rename/copy logic sometimes borrowed a pointer
to a structure without any provision for downstream to determine
which pointer is shared and which is not. This resulted in the
later clean-up code to sometimes double free such structure,
resulting in a segfault. This made -M and -C useless.
Another problem the earlier implementation had was that it
reordered the patches, and forced the logic to differentiate
renames and copies to depend on that particular order. This
problem was fixed by teaching rename/copy detection logic not to
do any reordering, and rename-copy differentiator not to depend
on the order of the patches. The diffs will leave rename/copy
detector in the same destination path order as the patch that
was fed into it. Some test vectors have been reordered to
accommodate this change.
It also adds a sanity check logic to the human-readable diff-raw
output to detect paths with embedded TAB and LF characters,
which cannot be expressed with that format. This idea came up
during a discussion with Chris Wedgwood.

[PATCH] Rename/copy detection fix.
The rename/copy detection logic in earlier round was only good
enough to show patch output and discussion on the mailing list
about the diff-raw format updates revealed many problems with
it. This patch fixes all the ones known to me, without making
things I want to do later impossible, mostly related to patch
reordering.
(1) Earlier rename/copy detector determined which one is rename
and which one is copy too early, which made it impossible
to later introduce diffcore transformers to reorder
patches. This patch fixes it by moving that logic to the
very end of the processing.
(2) Earlier output routine diff_flush() was pruning all the
"no-change" entries indiscriminatingly. This was done due
to my false assumption that one of the requirements in the
diff-raw output was not to show such an entry (which
resulted in my incorrect comment about "diff-helper never
being able to be equivalent to built-in diff driver"). My
special thanks go to Linus for correcting me about this.
When we produce diff-raw output, for the downstream to be
able to tell renames from copies, sometimes it _is_
necessary to output "no-change" entries, and this patch
adds diffcore_prune() function for doing it.
(3) Earlier diff_filepair structure was trying to be not too
specific about rename/copy operations, but the purpose of
the structure was to record one or two paths, which _was_
indeed about rename/copy. This patch discards xfrm_msg
field which was trying to be generic for this wrong reason,
and introduces a couple of fields (rename_score and
rename_rank) that are explicitly specific to rename/copy
logic. One thing to note is that the information in a
single diff_filepair structure _still_ does not distinguish
renames from copies, and it is deliberately so. This is to
allow patches to be reordered in later stages.
(4) This patch also adds some tests about diff-raw format
output and makes sure that necessary "no-change" entries
appear on the output.

[PATCH] Diffcore updates.
This moves the path selection logic from individual programs to a new
diffcore transformer (diff-tree still needs to have its own for
performance reasons). Also the header printing code in diff-tree was
tweaked not to produce anything when pickaxe is in effect and there is
nothing interesting to report. An interesting example is the following
in the GIT archive itself:
$ git-whatchanged -p -C -S'or something in a real script'

[PATCH] The diff-raw format updates.
Update the diff-raw format as Linus and I discussed, except that
it does not use sequence of underscore '_' letters to express
nonexistence. All '0' mode is used for that purpose instead.
The new diff-raw format can express rename/copy, and the earlier
restriction that -M and -C _must_ be used with the patch format
output is no longer necessary. The patch makes -M and -C flags
independent of -p flag, so you need to say git-whatchanged -M -p
to get the diff/patch format.
Updated are both documentations and tests.

[PATCH] Tweak diffcore-rename heuristics.
The heuristics so far was to compare file size change and xdelta

[PATCH] Introducing software archaeologist's tool "pickaxe".
This steals the "pickaxe" feature from JIT and make it available
to the bare Plumbing layer. From the command line, the user
gives a string he is intersted in.
Using the diff-core infrastructure previously introduced, it
filters the differences to limit the output only to the diffs
between <src> and <dst> where the string appears only in one but
not in the other. For example:
$ ./git-rev-list HEAD | ./git-diff-tree -Sdiff-tree-helper --stdin -M
would show the diffs that touch the string "diff-tree-helper".
In real software-archaeologist application, you would typically
look for a few to several lines of code and see where that code
came from.
The "pickaxe" module runs after "rename/copy detection" module,
so it even crosses the file rename boundary, as the above
example demonstrates.

[PATCH] Diff overhaul, adding half of copy detection.
This introduces the diff-core, the layer between the diff-tree
family and the external diff interface engine. The calls to the
interface diff-tree family uses (diff_change and diff_addremove)
have not changed and will not change. The purpose of the
diff-core layer is to provide an infrastructure to transform the
set of differences sent from the applications, before sending
them to the external diff interface.
The recently introduced rename detection code has been rewritten
to use the diff-core facility. When applications send in
separate creates and deletes, matching ones are transformed into
a single rename-and-edit diff, and sent out to the external diff
interface as such.
This patch also enhances the rename detection code further to be
able to detect copies. Currently this happens only as long as
copy sources appear as part of the modified files, but there
already is enough provision for callers to report unmodified
files to diff-core, so that they can be also used as copy source
candidates. Extending the callers this way will be done in a
separate patch.
Please see and marvel at how well this works by trying out the
newly added t/t4003-diff-rename-1.sh test script.

[PATCH] Deltification library work by Nicolas Pitre.
This patch adds the basic library functions to create and replay delta
information. Also included is a test-delta utility to validate the
code.
diff-delta was based on LibXDiff written by Davide Libenzi

[PATCH] A test case addition for strbuf regression
This test would have caught the strbuf eof condition gotcha,
hopefully fixed with my previous patch.

[PATCH] fix strbuf take #2
I just remembered why I placed that bogus "sb->len ==0 implies
sb->eof" condition there. We need at least something like this
to catch the normal EOF (that is, line termination immediately
followed by EOF) case. "if (feof(fp))" fires when we have
already read the eof, not when we are about read it.

merge-base: use the new lookup_commit_reference() helper function
This allows you to use tags for merge bases.
This allows you to use tags for merge bases.
commit: add "lookup_commit_reference()" helper function
It's pretty much the same as "lookup_commit()", but it will take
tags too, and look up the commit (if any) associated with them.

diff-tree: don't match non-directories as partial pathnames
This normally doesn't matter, but if you have a filename that is
sometimes a directory and sometimes a regular file (or symlink),
we don't want the regular file case to trigger a "partial match".

diff-tree: fix "whole sub-tree disappeared or appeared" case
We still need to check which part of the sub-tree is interesting.

diff-tree: fix up comparison of "interesting" sub-trees
We used to trigger the "interesting subdirectory" check for any
matching name that started with the same character series, regardless
of whether it had the matching slash or not.
