Linus Torvalds [Sat, 25 Mar 2006 04:13:22 +0000 (20:13 -0800)]
Use a *real* built-in diff generator

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" ]

git-apply: safety fixes

This was triggered by me testing the "@@" numbering shorthand by GNU
patch, which not only showed that git-apply thought it meant the number
was duplicated (when it means that the second number is 1), but my tests
showed than when git-apply mis-understood the number, it would then not
raise an alarm about it if the patch ended early.

Now, this doesn't actually _matter_, since with a three-line context, the
only case that "x,1" will be shorthanded to "x" is when x itself is 1 (in
which case git-apply got it right), but the fact that git-apply would also
silently accept truncated patches was a missed opportunity for additional
sanity-checking.

As pointed out by Junio, it may be dangerous to cut off people's names
after 15 bytes. If the name is encoded in an encoding which uses more
than one byte per code point we may end up with outputting garbage.
Instead of trying to do something smart, just output the entire name.
We don't gain much screen space by chopping it off anyway.

Furthermore, only output the file name if we actually found any
renames.

Fix up diffcore-rename scoring

The "score" calculation for diffcore-rename was totally broken.

It scaled "score" as

score = src_copied * MAX_SCORE / dst->size;

which means that you got a 100% similarity score even if src and dest were
different, if just every byte of dst was copied from src, even if source
was much larger than dst (eg we had copied 85% of the bytes, but _deleted_
the remaining 15%).

That's clearly bogus. We should do the score calculation relative not to
the destination size, but to the max size of the two.

This seems to fix it.
