Improve accuracy of check for presence of deflateBound.
ZLIB_VERNUM isn't defined in some zlib versions, so this patch does a proper
linking test in autoconf to see whether deflateBound exists in zlib. Also,
setting NO_DEFLATE_BOUND will also work for folk not using autoconf.

git-svn: fix dcommit clobbering when committing a series of diffs
Our revision number sent to SVN is set to the last revision we
committed if we've made any previous commits in a dcommit
invocation.
Although our SVN Editor code uses the delta of two (old) trees
to generate information to send upstream, it'll still send
complete resultant files upstream; even if the tree they're
based against is out-of-date.
The combination of sending a file that does not include the
latest changes, but set with a revision number of a commit we
just made will cause SVN to accept the resultant file even if it
was generated against an old tree.
More trouble was caused when fixing this because we were
rebasing uncessarily at times. We used git-diff-tree to check
the imported SVN revision against our HEAD, not the last tree we
committed to SVN. The unnecessary rebasing caused merge commits
upstream to SVN to fail.

Fortunately, we have checked out the first parent right before the merge

Make merge-recursive honor diff.renamelimit
It might be a sign of source code management gone bad, but when two branches
has diverged almost beyond recognition and time has come for the branches to
merge, the user is going to need all the help his tool can give him. Honoring
diff.renamelimit has great potential as a painkiller in such situations.
The painkiller effect could have been achieved by e.g. 'merge.renamelimit',
but the flexibility gained by a separate option is questionable: our user
would probably expect git to detect renames equally good when merging as
when diffing (I known I did).

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_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:

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.

Fix directory scanner to correctly ignore files without d_type

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,
and added some commentary to the cases.

Avoid scary errors about tagged trees/blobs during git-fetch
Ok, what is going on is:
- append_fetch_head() looks up the SHA1 for all heads (including tags):
if (get_sha1(head, sha1))
return error("Not a valid object name: %s", head);
- it then wants to check if it's a candidate for merging (because
fetching also does the whole "list which heads to merge" in case
it is going to be part of a "pull"):
commit = lookup_commit_reference(sha1);
if (!commit)
not_for_merge = 1;
- and that "lookup_commit_reference()" is just very vocal about the
case where it fails. It really shouldn't be, and it shouldn't
affect the actual end result, but that basically explains why
you get that scary warning.
In short, the warning is just bogus, and should be harmless, but
I agree that it's ugly. I think the appended patch should fix it.

git-blame shouldn't crash if run in an unmerged tree
If we are in the middle of resolving a merge conflict there may be
one or more files whose entries in the index represent an unmerged
state (index entries in the higher-order stages).
Attempting to run git-blame on any file in such a working directory
resulted in "fatal: internal error: ce_mode is 0" as we use the magic
marker for an unmerged entry is 0 (set up by things like diff-lib.c's
do_diff_cache() and builtin-read-tree.c's read_tree_unmerged())
and the ce_match_stat_basic() function gets upset about this.
I'm not entirely sure that the whole "ce_mode = 0" case is a good
idea to begin with, and maybe the right thing to do is to remove
that horrid freakish special case, but removing the internal error
seems to be the simplest fix for now.

the only reason that this did not lead to problems is the fact that we

This fixes an unnecessary empty line that we add to the log message when

This can happen with pickaxe or with rename following. The reason is that
we normally add an empty line between the commit and the diff, but we do
that even for the case where we've then suppressed the actual printing of
the diff.
This also updates a couple of tests that assumed the extraneous empty

Fix embarrassing "git log --follow" bug
It turns out that I completely broke "git log --follow" with my recent
patch to revision.c ("Fix revision log diff setup, avoid unnecessary diff
generation", commit b7bb760d5ed4881422673d32f869d140221d3564).
Why? Because --follow obviously requires the diff machinery to function,
exactly the same way pickaxe does.
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.

Must not modify the_index.cache as it may be passed to realloc at some point.
The index cache is not static, growing as new entries are added. If
entries are added after prune_cache is called, cache will no longer
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.
A more efficient patch would create a separate 'cache_base' value to
track the allocation and then fix things up when reallocation was
necessary, instead of the brute-force memmove used here.

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.
Practical tests showed 4.5x speedup for a 10% memory usage
increase.
