Correct priority of lightweight tags in git-describe.
We really want to always favor an annotated tag over a lightweight
tag when describing a commit. Unfortunately git-describe wasn't
doing this as it was favoring the depth attribute of a possible_tag
over the priority. Now priority is the highest sort and we only
consider a lightweight tag if no annotated tags were identified.
Rather than searching for the minimum tag using a simple loop we
now sort them using a stable sort algorithm, this way the possible
tags display in order if --debug gets used. The stable sort helps
to preseve the inherit topology/date order that we obtain during
our search loop.

Improve git-describe performance by reducing revision listing.
My prior version of git-describe ran very slowly on even reasonably
sized projects like git.git and linux.git as it tended to identify
a large number of possible tags and then needed to generate the
revision list for each of those tags to sort them and select the
best tag to describe the input commit.
All we really need is the number of commits in the input revision
which are not in the tag. We can generate these counts during
the revision walking and tag matching loop by assigning a color to
each tag and coloring the commits as we walk them. This limits us
to identifying no more than 26 possible tags, as there is limited
space available within the flags field of struct commit.
The limitation of 26 possible tags is hopefully not going to be a
problem in real usage, as most projects won't create 26 maintenance
releases and merge them back into a development trunk after the
development trunk was tagged with a release candidate tag. If that
does occur git-describe will start to revert to its old behavior of
using the newer maintenance release tag to describe the development
trunk, rather than the development trunk's own tag. The suggested
workaround would be to retag the development trunk's tip.
However since even 26 possible tags can take a while to generate a
description for on some projects I'm defaulting the limit to 10 but
offering the user --candidates to increase the number of possible
matches if they need a more accurate result. I specifically chose
10 for the default as it seems unlikely projects will have more
than 10 maintenance releases merged into a development trunk before
retagging the development trunk, and it seems to perform about the
same on linux.git as v1.4.4.4 git-describe.
A large amount of debugging information was also added during
the development of this change, so I've left it in to be toggled
on with --debug. It may be useful to the end user to help them
understand why git-describe took one particular tag over another.

Chose better tag names in git-describe after merges.
Recently git.git itself encountered a situation on its master and
next branches where git-describe stopped reporting 'v1.5.0-rc0-gN'
and instead started reporting 'v1.4.4.4-gN'. This appeared to be
a backward jump in version numbering.
The issue is that commit C in the diagram claims it is version
1.5.0, as the tag v1.5.0 is placed on commit 5. Yet commit W
claims it is version 1.4.4.4 as the tag v1.5.0 has an older tag

As it turns out this situation is very common. A bug fix applied

it should Just Work Right(tm).
Rather than taking the first tag that gets found git-describe will
now generate a list of all possible tags and select the one which
has the most number of commits in common with HEAD (or whatever
revision the user requested the description of).
This rule is based on the principle shown in the diagram above.
There are a large number of commits on the primary development branch
'master' which do not appear in the 'maint' branch, and many of
these are already tagged as part of v1.5.0-rc0. Additionally these

Better error messages for corrupt databases
This fixes another problem that Andy's case showed: git-fsck-objects
reports nonsensical results for corrupt objects.
There were actually two independent and confusing problems:
- when we had a zero-sized file and used map_sha1_file, mmap() would
return EINVAL, and git-fsck-objects would report that as an insane and
confusing error. I don't know when this was introduced, it might have
been there forever.
- when "parse_object()" returned NULL, fsck would say "object not found",
which can be very confusing, since obviously the object might "exist",
it's just unparseable because it's totally corrupt.
So this just makes "xmmap()" return NULL for a zero-sized object (which is
a valid thing pointer, exactly the same way "malloc()" can return NULL for
a zero-sized allocation). That fixes the first problem (but we could have
fixed it in the caller too - I don't personally much care whichever way it
goes, but maybe somebody should check that the NO_MMAP case does
something sane in this case too?).
And the second problem is solved by just making the error message slightly
clearer - the failure to parse an object may be because it's missing or

Improve merge performance by avoiding in-index merges.
In the early days of Git we performed a 3-way read-tree based merge
before attempting any specific merge strategy, as our core merge
strategies of merge-one-file and merge-recursive were slower script
based programs which took far longer to execute. This was a good
performance optimization in the past, as most merges were able to
be handled strictly by `read-tree -m -u`.
However now that merge-recursive is a C based program which performs
a full 3-way read-tree before it starts running we need to pay the
cost of the 3-way read-tree twice if we have to do any sort of file
level merging. This slows down some classes of simple merges which
`read-tree -m -u` could not handle but which merge-recursive does
automatically.
For a really trivial merge which can be handled entirely by
`read-tree -m -u`, skipping the read-tree and just going directly
into merge-recursive saves on average 50 ms on my PowerPC G4 system.
May sound odd, but it does appear to be true.
In a really simple merge which needs to use merge-recursive to handle
a file that was modified on both branches, skipping the read-tree
in git-merge saves on average almost 100 ms (on the same PowerPC G4)
as we avoid doing some work twice.
We only avoid `read-tree -m -u` if the only strategy to use is
merge-recursive, as not all merge strategies perform as well as
merge-recursive does.

send-email: work around double encoding of in-body From field.
git-send-email sends out the message taken from format-patch
output without quoting nor encoding. When copying the From:
line to form in-body From: field, it should not copy it
verbatim, because the From: for the header is quoted according
to RFC 2047 when not ASCII.
The original came from Jürgen Rühle, but I moved the
string munging into a separate function so that later other
people can tweak it more easily. Bugs introduced during the
translation are mine.
Since c869753e, core.filemode is hardwired to false on Cygwin.
So this test had no chance to succeed, since an early commit
(changing just the filemode) failed, and therefore all subsequent
tests.

git-checkout: handle local changes sanely when detaching HEAD
When switching branches, we usually first try read-tree to make
sure that we do not lose the local changes and then updated the
HEAD using update-ref. However, we detached and updated HEAD
before these checks, which was quite bad in a repository with
local changes.

Don't die in git-http-fetch when fetching packs.
My sp/mmap changes to pack-check.c modified the function such that
it expects packed_git.pack_size to be populated with the total
bytecount of the packfile by the caller.
But that isn't the case for packs obtained by git-http-fetch as
pack_size was not initialized before being accessed. This caused
verify_pack to think it had 2^32-21 bytes available when the
downloaded pack perhaps was only 305 bytes in length. The use_pack
function then later dies with "offset beyond end of packfile"
when computing the overall file checksum.

Replacing the system call pread() with lseek()/xread()/lseek() sequence.
Using cygwin with cygwin.dll before 1.5.22 the system call pread() is buggy.
This patch introduces NO_PREAD. If NO_PREAD is set git uses a sequence of
lseek()/xread()/lseek() to emulate pread.

It used to ignore the return value of the helper function; now, it
expects it to return 0, and stops iteration upon non-zero return
values; this value is then passed on as the return value of
for_each_reflog_ent().
Further, it makes no sense to force the parsing upon the helper
functions; for_each_reflog_ent() now calls the helper function with
old and new sha1, the email, the timestamp & timezone, and the message.

Do not ignore a detected patchfile brokenness.
find_header() function is used to read and parse the patchfile

Auto-quote config values in config.c:store_write_pair()
Suggested by Jakub Narebski <jnareb@gmail.com> on the list.
When we send a value to store_write_pair(), make sure that the value
that gets read out matches the one passed in. This means that for any
value that contains leading or trailing whitespace or any comment
character (# and ;), we need to surround it in quotes.

short i/o: fix calls to write to use xwrite or write_in_full
We have a number of badly checked write() calls. Often we are
expecting write() to write exactly the size we requested or fail,
this fails to handle interrupts or short writes. Switch to using
the new write_in_full(). Otherwise we at a minimum need to check
for EINTR and EAGAIN, where this is appropriate use xwrite().
Note, the changes to config handling are much larger and handled

short i/o: clean up the naming for the write_{in,or}_xxx family
We recently introduced a write_in_full() which would either write
the specified object or emit an error message and fail. In order
to fix the read side we now want to introduce a read_in_full()
but without an error emit. This patch cleans up the naming
of this family of calls:
1) convert the existing write_or_whine() to write_or_whine_pipe()
to better indicate its pipe specific nature,
2) convert the existing write_in_full() calls to write_or_whine()
to better indicate its nature,
3) introduce a write_in_full() providing a write or fail semantic,
and
4) convert write_or_whine() and write_or_whine_pipe() to use
write_in_full().
