Now, you can say "git diff --stat" (to get an idea how many changes are

Some words, e.g., `match', are special to expr(1), and cause strange
parsing effects. Track down all uses of expr and mangle the arguments
so that this isn't a problem.

This trivially avoids keeping the commit message data around after we
don't need it any more, avoiding a continually growing "git log" memory
footprint.
It's not a huge deal, but it's somewhat noticeable. For the current kernel
tree, doing a full "git log" I got
- before: /usr/bin/time git log > /dev/null
0.81user 0.02system 0:00.84elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (0major+8851minor)pagefaults 0swaps
- after: /usr/bin/time git log > /dev/null
0.79user 0.03system 0:00.83elapsed 100%CPU (0avgtext+0avgdata 0maxresident)k
0inputs+0outputs (0major+5039minor)pagefaults 0swaps
ie the touched pages dropped from 8851 to 5039. For the historic kernel
archive, the numbers are 18357->11037 minor page faults.
We could/should in theory free the commits themselves, but that's really a
lot harder, since during revision traversal we may hit the same commit
twice through different children having it as a parent, even after we've
shown it once (when that happens, we'll silently ignore it next time, but
we still need the "struct commit" to know).
And as the commit message data is clearly the biggest part of the commit,
this is the really easy 60% solution.

This target lists undocumented commands, and/or whose document
is not referenced from the main git documentation.
For now, there are some exceptions I added primarily because I
lack the energy to document them myself:
- merge backends (we should really document them)
- ssh-push/ssh-pull (does anybody still use them?)
- annotate and blame (maybe after one of them eats the other ;-)

When dealing with a commit log message for human consumption, it
never makes sense to keep a log that ends with an incomplete
line, so make it a part of the clean-up process done by
git-stripspace.

Spotted by Linus and Darrin Thompson. When we took a commit
message from -F <file> with an incomplete line, we appended "git
status" output, which ended up attaching a lone "#" at the end.
We still need the "do we have anything to commit?" check by
running "status" (which has to know what to do in different
cases with -i/-o/-a), but there is no point appending its output
to the proposed commit message given by the user.

We used to lose hunks that appear at the end and have only

Ok this really should be the good version. The option
handling has been reworked to be automation safe.
Currently to import the -mm tree I have to work around
git-apply by using patch. Because some of Andrews
patches in quilt will only apply with fuzz.
I started out implementing a --fuzz option and then I realized
fuzz is not a very safe concept for an automated system. What
you really want is a minimum number of context lines that must
match. This allows policy to be set without knowing how many
lines of context a patch actually provides. By default
the policy remains to match all provided lines of context.
Allowng git-apply to match a restricted set of context makes
it much easier to import the -mm tree into git. I am still only
processing 1.5 to 1.6 patches a second for the 692 patches in
2.6.17-rc1-mm2 is still painful but it does help.
If I just loop through all of Andrews patches in order
and run git-apply --index -C1 I process the entire patchset
in 1m53s or about 6 patches per second. So running
git-mailinfo, git-write-tree, git-commit-tree, and
git-update-ref everytime has a measurable impact,
and shows things can be speeded up even more.
All of these timings were taking on my poor 700Mhz Athlon
with 512MB of ram. So people with fast machiens should
see much better performance.
When a match is found after the number of context are reduced a
warning is generated. Since this is a rare event and possibly
dangerous this seems to make sense. Unless you are patching
a single file the error message is a little bit terse at
the moment, but it should be easy to go back and fix.
I have also updated the documentation for git-apply to reflect
the new -C option that sets the minimum number of context
lines that must match.

This makes things that include revision.h build again.
Blame is also built, but I am not sure how well it works (or how
well it worked to begin with) -- it was relying on tree-diff to
be using whatever pathspec was used the last time, which smells
a bit suspicious.

Without this flag, "git log -p paths..." shows commits that
touch the specified paths, and diffs about the same specified
paths. With this, the full diff is shown for commits that touch
the specified paths.

The way tree-diff was set up assumed we would use only one set
of pathspec during the entire life of the program. Move the
pathspec related static variables out to diff_options structure
so that we can filter commits with one set of paths while show
the actual diffs using different set of paths.
I suspect this breaks blame.c, and makes "git log paths..." to
default to the --full-diff, the latter of which is dealt with
the next commit.

This separates out the part that deals with one-commit diff-tree
(and --stdin form) into a separate log-tree module.
There are two goals with this. The more important one is to be
able to make this part available to "git log --diff", so that we
can have a native "git whatchanged" command. Another is to
simplify the commit log generation part simpler.

The parent rewriting feature caused us to create the whole history in one
go, and then simplify it later, because of how rewrite_parents() had been
written. However, with a little tweaking, it's perfectly possible to do
even that one incrementally.
Right now, this doesn't really much matter, because every user of
"--parents" will probably generally _also_ use "--topo-order", which will
cause the old non-incremental behaviour anyway. However, I'm hopeful that
we could make even the topological sort incremental, or at least
_partially_ so (for example, make it incremental up to the first merge).
In the meantime, this at least moves things in the right direction, and
removes a strange special case.

Compiling this module gave the following warnings (some double dutch!):
xdiff/xdiffi.c: In functie 'xdl_recs_cmp':
xdiff/xdiffi.c:298: let op: 'spl.i1' may be used uninitialized in this function
xdiff/xdiffi.c:298: let op: 'spl.i2' may be used uninitialized in this function
xdiff/xdiffi.c:219: let op: 'fbest1' may be used uninitialized in this function
xdiff/xdiffi.c:219: let op: 'bbest1' may be used uninitialized in this function
A superficial tracking of their usage, without deeper knowledge about the
algorithm, indeed confirms that there are code paths on which these
variables will be used uninitialized. In practice these code paths might never
be reached, but then these fixes will not change the algorithm. If these
code paths are ever reached we now at least have a predictable outcome. And
should the very small performance impact of these initializations be
noticeable, then they should at least be replaced by comments why certain
code paths will never be reached.
Some extra initializations in this patch now fix the warnings.

When a broken pair is matched up by rename detector to be merged
back, we do not want to say it is "dissimilar" with the
similarity index. The output should just say they were changed,
taking the break score left by the earlier diffcore-break run if
any.
