6de08ae688 Log ref updates to logs/refs/<ref>
If config parameter core.logAllRefUpdates is true or the log
file already exists then append a line to ".git/logs/refs/<ref>"
whenever git-update-ref <ref> is executed.  Each log line contains
the following information:

  oldsha1 <SP> newsha1 <SP> committer <LF>

where committer is the current user, date, time and timezone in
the standard GIT ident format.  If the caller is unable to append
to the log file then git-update-ref will fail without updating <ref>.

An optional message may be included in the log line with the -m flag.

This conversion also adds the '-m' switch to update-ref allowing
the caller to record why the ref is changing.  At present this is
merely copied down into the ref_lock API.

4bd18c43d9 Improve abstraction of ref lock/write.
Created 'struct ref_lock' to contain the data necessary to perform
a ref update.  This change improves writing a ref as the file names
are generated only once (rather than twice) and supports following
symrefs (up to the maximum depth).  Further the ref_lock structure
provides room to extend the update API with ref logging.

Apparently <stdint.h> is not enough for uint32_t on OpenBSD; use
"unsigned int" -- hopefully that would stay 32-bit on every
platform we care about, at least until we update the pack-index
file format.

Our sha1 routines optimized for architectures use uint32_t and
expects '#include <stdint.h>' to be enough, so OpenBSD on arm or
ppc might have similar issues down the road, I dunno.

ff45715ce5 pack-object: slightly more efficient
Avoid creating a delta index for objects with maximum depth since they
are not going to be used as delta base anyway.  This also reduce peak
memory usage slightly as the current object's delta index is not useful
until the next object in the loop is considered for deltification. This
saves a bit more than 1% on CPU usage.

4e8da19581 simple euristic for further free packing improvements
Given that the early eviction of objects with maximum delta depth
may exhibit bad packing on its own, why not considering a bias against
deep base objects in try_delta() to mitigate that bad behavior.

This patch adjust the MAX_size allowed for a delta based on the depth of
the base object as well as enabling the early eviction of max depth
objects from the object window.  When used separately, those two things
produce slightly better and much worse results respectively.  But their
combined effect is a surprising significant packing improvement.

With this really simple patch the GIT repo gets nearly 15% smaller, and
the Linux kernel repo about 5% smaller, with no significantly measurable
CPU usage difference.

checkers to kill duplicates.

It'll default to using /usr/sbin/sendmail or /usr/lib/sendmail

server on localhost.

613f02739a read-tree -u one-way merge fix to check out locally modified paths.
The "-u" flag means "update the working tree files", but to
other types of merges, it also implies "I want to keep my local
changes" -- because they prevent local changes from getting lost
by using verify_uptodate.  The one-way merge is different from
other merges in that its purpose is opposite of doing something
else while keeping unrelated local changes.  The point of
one-way merge is to nuke local changes.  So while it feels
somewhat wrong that this actively loses local changes, it is the
right thing to do.

Testing and feedback for correctness and completeness of all formats

Nested expansions are also supported.

More than one alias file to be used.

All alias file formats must still of be the same type, though.

Two git repo-config keys are required for this
(as suggested by Ryan Anderson):

    sendemail.aliasfiletype = (mutt|gnus|pine|mailrc)

1e2398d7fa builtin-grep: use external grep when we can take advantage of it
It's not perfect, but it gets the "git grep some-random-string" down to
the good old half-a-second range for the kernel.

It should convert more of the argument flags for "grep", that should be
trivial to expand (I did a few just as an example). It should also bother
to try to return the right "hit" value (which it doesn't, right now - the
code is kind of there, but I didn't actually bother to do it _right_).

Also, right now it _just_ limits by number of arguments, but it should
also strictly speaking limit by total argument size (ie add up the length
of the filenames, and do the "exec_grep()" flush call if it's bigger than
some random value like 32kB).

But I think that it's _conceptually_ doing all the right things, and it
seems to work. So maybe somebody else can do some of the final polish.

c68998f5b5 Simplify "git reset --hard"
Now that the one-way merge strategy does the right thing wrt files that do
not exist in the result, just remove all the random crud we did in "git
reset" to do this all by hand.

Instead, just pass in "-u" to git-read-tree when we do a hard reset, and
depend on git-read-tree to update the working tree appropriately.

This basically means that git reset turns into

	# Always update the HEAD ref
	git update-ref HEAD "$rev"

	case "--soft"
		# do nothing to index/working tree
	case "--hard"
		# read index _and_ update working tree
		git-read-tree --reset -u "$rev"
	case "--mixed"
		# update just index, report on working tree differences
		git-read-tree --reset "$rev"
		git-update-index --refresh

which is what it was always semantically doing, it just did it in a
rather strange way because it was written to not expect git-read-tree to
do anything to the working tree.

76b99b8161 Allow one-way tree merge to remove old files
For some random reason (probably just because nobody noticed), the one-way
merge strategy didn't mark deleted files as deleted, so if you used

it would update the files that got changed in the index, but it would not
delete the files that got deleted.

This should fix it, and I can't imagine that anybody depends on the old
strange "update only existing files" behaviour.

We used to parse "-U" and "--unified" as part of the GIT_DIFF_OPTS
environment variable, but strangely enough we would _not_ parse them as
part of the normal diff command line (where we only accepted "-u").

This adds parsing of -U and --unified, both with an optional numeric
argument. So now you can just say

	git diff --unified=5

to get a unified diff with a five-line context, instead of having to do
something silly like

	GIT_DIFF_OPTS="--unified=5" git diff -u

(that silly format does continue to still work, of course).
