Introduce tree-walk.[ch] and move "struct tree_desc" and
associated functions from various places.
Rename DIFF_FILE_CANON_MODE(mode) macro to canon_mode(mode) and
move it to cache.h. This macro returns the canonicalized
st_mode value in the host byte order for files, symlinks and
directories -- to be compared with a tree_desc entry.
create_ce_mode(mode) in cache.h is similar but is intended to be
used for index entries (so it does not work for directories) and
returns the value in the network byte order.

When the executable bit is untrustworthy and when we are
comparing the tree with the working tree, we tried to reuse the
mode bits recorded in the index incorrectly (the computation was
bogus on little endian architectures). Just use mode from index
when it is a regular file.

With the new --boundary flag, the output from rev-list includes
the UNINTERESING commits at the boundary, which are usually not
shown. Their object names are prefixed with '-'.
For example, with this graph:
C side
/
A---B---D master
You would get something like this:
$ git rev-list --boundary --header --parents side..master
D B
tree D^{tree}
parent B
... log message for commit D here ...
\0-B A
tree B^{tree}
parent A
... log message for commit B here ...
\0

We do not need to track object refs, neither we need to save commit
unless we are doing verbose header. A lot of traversal happens
inside prepare_revision_walk() these days so setting things up before
calling that function is necessary.

The speed of the built-in diff generator is nice; but the function names
shown by `diff -p' are /really/ nice. And I hate having to choose. So,
we hack xdiff to find the function names and print them.
xdiff has grown a flag to say whether to dig up the function names. The
builtin_diff function passes this flag unconditionally. I suppose it
could parse GIT_DIFF_OPTS, but it doesn't at the moment. I've also
reintroduced the `function name' into the test suite, from which it was
removed in commit 3ce8f089.
The function names are parsed by a particularly stupid algorithm at the
moment: it just tries to find a line in the `old' file, from before the
start of the hunk, whose first character looks plausible. Still, it's
most definitely a start.

For some reason, I need ALL_LDFLAGS in the git target only on
AIX. Once it builds, only one test "fails" on AIX 5.1 with
1.3.0.rc1, t5500-fetch-pack.sh, but it looks like it's some
odd tool problem in the tester + my setup and not a real bug.

All of the things that were not in the "master" branch were
either cooked long enough in "next" without causing problems
(e.g. insanely fast rename detector or true built-in diff) or
isolated in a specific subsystem (e.g. tar-tree and svnimport).
So I am clearing the deck to prepare for a 1.3.0. Remaining
wrinkles, if any, will be ironed in the "master" branch.

Without the --directory flag, git-ls-files wouldn't ever list directories,
producing no output for empty directories, which is good since they cannot
be added and they bear no content, even untracked one (if Git ever starts
tracking directories on their own, this should obviously change since the
content notion will change).
With the --directory flag however, git-ls-files would list even empty
directories. This may be good in some situations but sometimes you want to
prevent that. This patch adds a --no-empty-directory option which makes
git-ls-files omit empty directories.

When passing in a pathname pattern without the "--" separator on the
command line, we verify that the pathnames in question exist. However,
there were two bugs in that verification:
- git-rev-parse would only check the first pathname, and silently allow
any invalid subsequent pathname, whether it existed or not (which
defeats the purpose of the check, and is also inconsistent with what
git-rev-list actually does)
- git-rev-list (and "git log" etc) would check each filename, but if the
check failed, it would print the error using the first one, i.e.:
[torvalds@g5 git]$ git log Makefile bad-file
fatal: 'Makefile': No such file or directory
instead of saying that it's 'bad-file' that doesn't exist.
This fixes both bugs.

The first was a simple typo where I put $yc instead of [yc $row].
The second was that I broke the logic for keeping up with fast
movement through the commits, e.g. when you select a commit and then
press down-arrow and let it autorepeat. That got broken when I
changed the merge diff display to use git-diff-tree --cc.

The point where the line for a parent joins to the first child
shown is visually different from the lines to the other children,
because the line doesn't branch, but terminates at the child.
Because of this, we now treat the first child a little differently
in the optimizer, and we draw its link in drawlineseg rather
than drawparentlinks. This improves the appearance of the graph.

It seems Tk 8.4 can't draw arrows on diagonal line segments. This
adds code to the optimizer to make the last bit of a line go vertically
before being terminated with an arrow pointing downwards, so that
it will be drawn correctly by Tk 8.4.

Lines in a diff beginning with --- or +++ were not being displayed
at all. Thanks to Robert Fitzsimons for pointing out the obvious
fix, that lines beginning with --- or +++ are only to be suppressed
in the diff header. I also took the opportunity to replace a regexp
call with a couple of string compare calls, which should be faster.

If you clicked on a line, so that it was drawn double-thickness,
and then scrolled to bring on-screen a child that hadn't previously
been drawn, the lines from it to the selected line were drawn
single-thickness. This fixes it so they are drawn double-thickness.
This also removes an unnecessary setting of phase in drawrest.

Now we don't parse the commits as we are reading them, we just put
commit data on a list as a blob, and instead parse the commit when
we need the various parts of it, such as when a commit is drawn on
the canvas. This makes searching a bit more interesting: now we
scan through the commit blobs doing a string or regexp match to find
commits that might match, then for those that might match, we parse
the commit info (if it isn't already parsed) and do the matching
for the various fields as before.

This rearranges the code a little to eliminate some procedure calls
and reduce the number of globals accessed. It makes rowidlist and
rowoffsets lists rather than arrays, and removes the lineid array,
since $lineid($l) was the same as [lindex $displayorder $l], and the
latter is a little faster.

This just does the simple thing of resetting everything, reading all
the commits, and redoing the whole layout from scratch. Hopefully
things are now fast enough that this simple approach is acceptable.
Also, this fits in better with future plans for adding the ability
to restrict the tree to just a few files and then expand back to
the whole tree.

This is a new version of gitk which is much faster and has much better
graph layout. It achieves the speed by only drawing the parts of the
canvases that are actually visible. It also draws the commits in the
order that git-rev-list produces them, so if you use -d, you need to
have a recent enough git-rev-list that understands the --date-order
flag.

We should be safely able to import histories with thousands
of revisions without hogging up lots of memory.
With this, we lose the ability to autocorrect mistakes when
people specify revisions in reverse, but it's probably no longer
a problem since we only have one method of log parsing nowadays.
I've added an extra check to ensure that revision numbers do
increment.
Also, increment the version number to 0.11.0. I really should
just call it 1.0 soon...

- Omit ---/+++ header unless we emit diff output;
- Detect and punt binary diff like GNU does;
- Honor GIT_DIFF_OPTS minimally (only -u<number> and
--unified=<number> are currently supported);
- Omit line count of 1 from "@@ -l,k +m,n @@" hunk header
(i.e. when k == 1 or n == 1)
- Adjust testsuite for the lack of -p support.

This uses a simplified libxdiff setup to generate unified diffs _without_
doing fork/execve of GNU "diff".
This has several huge advantages, for example:
Before:
[torvalds@g5 linux]$ time git diff v2.6.16.. > /dev/null
real 0m24.818s
user 0m13.332s
sys 0m8.664s
After:
[torvalds@g5 linux]$ time git diff v2.6.16.. > /dev/null
real 0m4.563s
user 0m2.944s
sys 0m1.580s
and the fact that this should be a lot more portable (ie we can ignore all
the issues with doing fork/execve under Windows).
Perhaps even more importantly, this allows us to do diffs without actually
ever writing out the git file contents to a temporary file (and without
any of the shell quoting issues on filenames etc etc).
NOTE! THIS PATCH DOES NOT DO THAT OPTIMIZATION YET! I was lazy, and the
current "diff-core" code actually will always write the temp-files,
because it used to be something that you simply had to do. So this current
one actually writes a temp-file like before, and then reads it into memory
again just to do the diff. Stupid.
But if this basic infrastructure is accepted, we can start switching over
diff-core to not write temp-files, which should speed things up even
further, especially when doing big tree-to-tree diffs.
Now, in the interest of full disclosure, I should also point out a few
downsides:
- the libxdiff algorithm is different, and I bet GNU diff has gotten a
lot more testing. And the thing is, generating a diff is not an exact
science - you can get two different diffs (and you will), and they can
both be perfectly valid. So it's not possible to "validate" the
libxdiff output by just comparing it against GNU diff.
- GNU diff does some nice eye-candy, like trying to figure out what the
last function was, and adding that information to the "@@ .." line.
libxdiff doesn't do that.
- The libxdiff thing has some known deficiencies. In particular, it gets
the "\No newline at end of file" case wrong. So this is currently for
the experimental branch only. I hope Davide will help fix it.
That said, I think the huge performance advantage, and the fact that it
integrates better is definitely worth it. But it should go into a
development branch at least due to the missing newline issue.
Technical note: this is based on libxdiff-0.17, but I did some surgery to
get rid of the extraneous fat - stuff that git doesn't need, and seriously
cutting down on mmfile_t, which had much more capabilities than the diff
algorithm either needed or used. In this version, "mmfile_t" is just a
trivial <pointer,length> tuple.
That said, I tried to keep the differences to simple removals, so that you
can do a diff between this and the libxdiff origin, and you'll basically
see just things getting deleted. Even the mmfile_t simplifications are
left in a state where the diffs should be readable.
Apologies to Davide, whom I'd love to get feedback on this all from (I
wrote my own "fill_mmfile()" for the new simpler mmfile_t format: the old
complex format had a helper function for that, but I did my surgery with
the goal in mind that eventually we _should_ just do
mmfile_t mf;
buf = read_sha1_file(sha1, type, &size);
mf->ptr = buf;
mf->size = size;
.. use "mf" directly ..
which was really a nightmare with the old "helpful" mmfile_t, and really
is that easy with the new cut-down interfaces).
[ Btw, as any hawk-eye can see from the diff, this was actually generated
with itself, so it is "self-hosting". That's about all the testing it
has gotten, along with the above kernel diff, which eye-balls correctly,
but shows the newline issue when you double-check it with "git-apply" ]
