git-rebase--interactive.sh: Make 3-way merge strategies work for -p.

git-rebase--interactive.sh used to pass all parents of a merge commit to
git-merge, which means that we have at least 3 heads to merge: HEAD,
first parent and second parent. So 3-way merge strategies like recursive
wouldn't work.

Fortunately, we have checked out the first parent right before the merge
anyway, so that is HEAD. Therefore we can drop simply it from the list
of parents, making 3-way strategies work for merge commits with only
two parents.

Linus Torvalds [Sat, 20 Oct 2007 19:31:31 +0000 (12:31 -0700)]
Fix diffcore-break total breakage

Ok, so on the kernel list, some people noticed that "git log --follow"
doesn't work too well with some files in the x86 merge, because a lot of
files got renamed in very special ways.

In particular, there was a pattern of doing single commits with renames
that looked basically like

 - rename "filename.h" -> "filename_64.h"
 - create new "filename.c" that includes "filename_32.h" or
   "filename_64.h" depending on whether we're 32-bit or 64-bit.

which was preparatory for smushing the two trees together.

Now, there's two issues here:

 - "filename.c" *remained*. Yes, it was a rename, but there was a new file
   created with the old name in the same commit. This was important,
   because we wanted each commit to compile properly, so that it was
   bisectable, so splitting the rename into one commit and the "create
   helper file" into another was *not* an option.

   So we need to break associations where the contents change too much.
   Fine. We have the -B flag for that. When we break things up, then the
   rename detection will be able to figure out whether there are better
   alternatives.

 - "git log --follow" didn't with with -B.

Now, the second case was really simple: we use a different "diffopt"
structure for the rename detection than the basic one (which we use for
showing the diffs). So that second case is trivially fixed by a trivial
one-liner that just copies the break_opt values from the "real" diffopts
to the one used for rename following. So now "git log -B --follow" works
fine:

diff --git a/tree-diff.c b/tree-diff.c
index 26bdbdd..7c261fd 100644
--- a/tree-diff.c
+++ b/tree-diff.c

  diff_opts.output_format = DIFF_FORMAT_NO_OUTPUT;
  diff_opts.single_follow = opt->paths[0];

  paths[0] = NULL;
  diff_tree_setup_paths(paths, &diff_opts);
  if (diff_setup_done(&diff_opts) < 0)

however, the end result does *not* work. Because our diffcore-break.c
logic is totally bogus!

In particular:

 - it used to do

if (base_size < MINIMUM_BREAK_SIZE)
return 0; /* we do not break too small filepair */

   which basically says "don't bother to break small files". But that
   "base_size" is the *smaller* of the two sizes, which means that if some
   large file was rewritten into one that just includes another file, we
   would look at the (small) result, and decide that it's smaller than the
   break size, so it cannot be worth it to break it up! Even if the other
   side was ten times bigger and looked *nothing* like the samell file!

   That's clearly bogus. I replaced "base_size" with "max_size", so that
   we compare the *bigger* of the filepair with the break size.

 - It calculated a "merge_score", which was the score needed to merge it
   back together if nothing else wanted it. But even if it was *so*
   different that we would never want to merge it back, we wouldn't
   consider it a break! That makes no sense. So I added

if (*merge_score_p > break_score)
return 1;

   to make it clear that if we wouldn't want to merge it at the end, it
   was *definitely* a break.

 - It compared the whole "extent of damage", counting all inserts and
   deletes, but it based this score on the "base_size", and generated the
   damage score with

delta_size = src_removed + literal_added;
damage_score = delta_size * MAX_SCORE / base_size;

   but that makes no sense either, since quite often, this will result in
   a number that is *bigger* than MAX_SCORE! Why? Because base_size is
   (again) the smaller of the two files we compare, and when you start out
   from a small file and add a lot (or start out from a large file and
   remove a lot), the base_size is going to be much smaller than the
   damage!

   Again, the fix was to replace "base_size" with "max_size", at which
   point the damage actually becomes a sane percentage of the whole.

With these changes in place, not only does "git log -B --follow" work for
the case that triggered this in the first place, ie now

git log -B --follow arch/x86/kernel/vmlinux_64.lds.S

actually gives reasonable results. But I also wanted to verify it in
general, by doing a full-history

git log --stat -B -C

on my kernel tree with the old code and the new code.

There's some tweaking to be done, but generally, the new code generates
much better results wrt breaking up files (and then finding better rename
candidates). Here's a few examples of the "--stat" output:

 - This:
include/asm-x86/Kbuild        |    2 -
include/asm-x86/debugreg.h    |   79 +++++++++++++++++++++++++++++++++++------
include/asm-x86/debugreg_32.h |   64 ---------------------------------
include/asm-x86/debugreg_64.h |   65 ---------------------------------
4 files changed, 68 insertions(+), 142 deletions(-)

      Becomes:

include/asm-x86/Kbuild                        |    2 -
include/asm-x86/{debugreg_64.h => debugreg.h} |    9 +++-
include/asm-x86/debugreg_32.h                 |   64 -------------------------
3 files changed, 7 insertions(+), 68 deletions(-)

 - This:
include/asm-x86/bug.h    |   41 +++++++++++++++++++++++++++++++++++++++--
include/asm-x86/bug_32.h |   37 -------------------------------------
include/asm-x86/bug_64.h |   34 ----------------------------------
3 files changed, 39 insertions(+), 73 deletions(-)

      Becomes

include/asm-x86/{bug_64.h => bug.h} |   20 +++++++++++++-----
include/asm-x86/bug_32.h            |   37 -----------------------------------
2 files changed, 14 insertions(+), 43 deletions(-)

Now, in some other cases, it does actually turn a rename into a real
"delete+create" pair, and then the diff is usually bigger, so truth in
advertizing: it doesn't always generate a nicer diff. But for what -B was
meant for, I think this is a big improvement, and I suspect those cases
where it generates a bigger diff are tweakable.

So I think this diff fixes a real bug, but we might still want to tweak
the default values and perhaps the exact rules for when a break happens.

That happened in the case of a pathname that was ignored, and we did
not ask for "dir->show_ignored". That test used to be *together*
with the "DTYPE(de) != DT_DIR", but splitting the two tests up
means that we can do that (common) test before we even bother to
calculate the real dtype.

Of course, that optimization only matters for systems that don't
have, or don't fill in DTYPE properly.

I also clarified the real relationship between "exclude" and
"dir->show_ignored". It used to do

if (exclude != dir->show_ignored) {
..

which wasn't exactly obvious, because it triggers for two different
cases:

 - the path is marked excluded, but we are not interested in ignored
   files: ignore it

 - the path is *not* excluded, but we *are* interested in ignored
   files: ignore it unless it's a directory, in which case we might
   have ignored files inside the directory and need to recurse
   into it).

so this splits them into those two cases, since the first case
doesn't even care about the type.

I also made a the DT_UNKNOWN case a separate helper function,

So everybody is away right now, but considering that nobody even noticed
this bug, I don't think it matters. But for the record, here's the trivial
one-liner fix (well, two, since I also fixed the comment).

Because of the nature of the bug, if you ask for patches when following
(which is one of the things I normally do), the bug is hidden, because
then the request for diff output will automatically also enable the diffs
themselves.

So while "git log --follow <filename>" didn't work, adding a "-p"
magically made it work again even without this fix.

git-gui: accept versions containing text annotations, like 1.5.3.mingw.1

This commit teaches git-gui to accept versions with annotations
that start with text and optionally end with a dot followed by
a number.

This is needed by the current versioning scheme of msysgit,

is not limited to this use case. Any version of the form
<numeric version>.<anytext>.<number> would be parsed and only

point at the base of the allocation, and realloc will not be happy.

I verified that this was the only place in the current source which
modified any index_state.cache elements aside from the alloc/realloc
calls in read-cache by changing the type of the element to 'struct
cache_entry ** const cache' and recompiling.

diffcore-rename: cache file deltas

We find rename candidates by computing a fingerprint hash of
each file, and then comparing those fingerprints. There are
inherently O(n^2) comparisons, so it pays in CPU time to
hoist the (rather expensive) computation of the fingerprint
out of that loop (or to cache it once we have computed it once).

Previously, we didn't keep the filespec information around
because then we had the potential to consume a great deal of
memory. However, instead of keeping all of the filespec
data, we can instead just keep the fingerprint.

This patch implements and uses diff_free_filespec_data_large
to accomplish that goal. We also have to change
estimate_similarity not to needlessly repopulate the
filespec data when we already have the hash.

Do not over-quote the -f envelopesender value.

Without this, the value passed to sendmail would have an extra set of
single quotes.  At least exim's sendmail emulation would object to that:

    exim: bad -f address "'list-addr@example.org'": malformed address: ' \
      may not follow 'list-addr@example.org
