Remove the temp file if it is empty after the request has failed
After using cg-update to pull, empty files named *.temp are left in
the various subdirectories of .git/objects/. These are created by
git-http-fetch to hold data as it's being fetched from the remote
repository. They are left behind after a transfer error so that the

GIT 0.99.9
Done in 0.99.9
==============
Ports
~~~~~
* Cygwin port [HPA].
* OpenBSD build [Merlyn and others].
Fixes
~~~~~
* clone request over git native protocol from a repository with
too many refs did not work; this has been fixed.
* git-daemon got safer for kernel.org use [HPA].
* Extended SHA1 parser was not enforcing uniqueness for
abbreviated SHA1; this has been fixed.
* http transport does not barf on funny characters in URL.
* The ref naming restrictions have been formalized and the
coreish refuses to create funny refs; we still need to audit
importers. See git-check-ref-format(1).
New Features and Commands
~~~~~~~~~~~~~~~~~~~~~~~~~
* .git/config file as a per-repository configuration mechanism,
and some commands understand it [Linus]. See
git(7).
* The core.filemode configuration item can be used to make us a
bit more FAT friendly. See git(7).
* The extended SHA1 notation acquired Peel-the-onion operator
^{type} and ^{}. See git-rev-parse(1).
* SVN importer [Matthias]. See git-svnimport(1).
* .git/objects/[0-9a-f]{2} directories are created on demand,
and removed when becomes empty after prune-packed [Linus].
* Filenames output from various commands without -z option are
quoted when they embed funny characters (TAB and LF) using
C-style quoting within double-quotes, to match the proposed
GNU diff/patch notation [me, but many people contributed in
the discussion].
* git-mv is expected to be a better replacement for git-rename.
While the latter has two parameter restriction, it acts more
like the regular 'mv' that can move multiple things to one
destinatino directory [Josef Weidendorfer].
* git-checkout can take filenames to revert the changes to
them. See git-checkout(1)
* The new program git-am is a replacement for git-applymbox that
has saner command line options and a bit easier to use when a
patch does not apply cleanly.
* git-ls-remote can show unwrapped onions using ^{} notation, to
help Cogito to track tags.
* git-merge-recursive backend can merge unrelated projects.
* git-clone over native transport leaves the result packed.
* git-http-fetch issues multiple requests in parallel when
underlying cURL library supports it [Nick and Daniel].
* git-fetch-pack and git-upload-pack try harder to figure out
better common commits [Johannes].
* git-read-tree -u removes a directory when it makes it empty.
* git-diff-* records abbreviated SHA1 names of original and
resulting blob; this sometimes helps to apply otherwise an
unapplicable patch by falling back to 3-way merge.
* git-format-patch now takes series of from..to rev ranges and
with '-m --stdout', writes them out to the standard output.
This can be piped to 'git-am' to implement cheaper
cherry-picking.
* git-tag takes '-u' to specify the tag signer identity [Linus].
* git-rev-list can take optional pathspecs to skip commits that
do not touch them (--dense) [Linus].
* Comes with new and improved gitk [Paulus and Linus].

Be more careful about reference parsing
This does two things:
- we don't allow "." and ".." as components of a refname. Thus get_sha1()
will not accept "./refname" as being the same as "refname" any more.
- git-rev-parse stops doing revision translation after seeing a pathname,
to match the brhaviour of all the tools (once we see a pathname,
everything else will also be parsed as a pathname).
Basically, if you did
git log *
and "gitk" was somewhere in the "*", we don't want to replace the filename
"gitk" with the SHA1 of the branch with the same name.
Of course, if there is any change of ambiguity, you should always use "--"
to make it explicit what are filenames and what are revisions, but this
makes the normal cases sane. The refname rule also means that instead of
the "--", you can do the same thing we're used to doing with filenames
that start with a slash: use "./filename" instead, and now it's a
filename, not an option (and not a revision).
So "git log ./*.c" is now actually a perfectly valid thing to do, even if
the first C-file might have the same name as a branch.
Trivial test:
git-rev-parse gitk ./gitk gitk
should output something like
9843c3074dfbf57117565f6b7c93e3e6812857ee
./gitk
gitk
where the "./gitk" isn't seen as a revision, and the second "gitk" is a
filename simply because we've seen filenames already, and thus stopped
doing revision parsing.

Be marginally more careful about removing objects
The git philosophy when it comes to disk accesses is "Laugh in the face of
danger".
Notably, since we never modify an existing object, we don't really care
that deeply about flushing things to disk, since even if the machine
crashes in the middle of a git operation, you can never really have lost
any old work. At most, you'd need to figure out the proper heads (which
git-fsck-objects can do for you) and re-do the operation.
However, there's two exceptions to this: pruning and repacking. Those
operations will actually _delete_ old objects that they know about in
other ways (ie that they just repacked, or that they have found in other
places).
However, since they actually modify old state, we should thus be a bit
more careful about them. If the machine crashes and the duplicate new
objects haven't been flushed to disk, you can actually be in trouble.
This is trivially stupid about it by calling "sync" before removing the
objects. Not very smart, but we're talking about special operations than
are usually done once a week if that.

[PATCH] Make "gitk" work better with dense revlists
To generate the diff for a commit, gitk used to do
git-diff-tree -p -C $p $id
(and same thing to generate filenames, except using just "-r" there) which
does actually generate the diff from the parent to the $id, exactly like
it meant to do.
However, that really sucks with --dense, where the "parent" information
has all been rewritten to point to the previous commit. The diff actually
works exactly right, but now it's the diff of the _whole_ sequence of
commits all the way to the previous commit that last changed the file(s)
that we are looking at.
And that's really not what we want 99.9% of the time, even if it may be
perfectly sensible. Not only will the diff not actually match the commit
message, but it will usually be _huge_, and all of it will be totally
uninteresting to us, since we were only interested in a particular set of
files.
It also doesn't match what we do when we write the patch to a file.
So this makes gitk just show the diff of _that_ commit.
We might even want to have some way to limit the diff to only the
filenames we're interested in, but it's often nice to see what else
changed at the same time, so that's secondary.
The merge diff handling is left alone, although I think that should also
be changed to only look at what that _particular_ merge did, not what it
did when compared to the faked-out parents.

git-rev-list: do not forget non-commit refs
What happens is that the new logic decides that if it can't look up a
commit reference (ie "get_commit_reference()" returns NULL), the thing
must be a pathname.
Fair enough.
But wrong.
The thing is, it may be a perfectly fine ref that _isn't_ a commit. In
git, you have a tag that points to your PGP key, and in the kernel, I have
a tag that points to a tree (and a direct ref that points to that tree
too, for that matter).
So the rule is (as for all the other programs that mix revs and pathnames)
not that we only accept commit references, but _any_ valid object ref.
If the object then isn't a commit ref, git-rev-list will either ignore it,
or add it to the list of non-commit objects (if using "--objects").
The solution is to move the "get_sha1()" out of get_commit_reference(),
and into the callers. In fact, we already _have_ the SHA1 in the case of
the handle_all() loop, since for_each_ref() will have done it for us, so
this is the correct thing to do anyway.
This patch (on top of the original one) does exactly that.

git-rev-list: make --dense the default (and introduce "--sparse")
This actually does three things:
- make "--dense" the default for git-rev-list. Since dense is a no-op if
no filenames are given, this doesn't actually change any historical
behaviour, but it's logically the right default (if we want to prune on
filenames, do it fully. The sparse "merge-only" thing may be useful,
but it's not what you'd normally expect)
- make "git-rev-parse" show the default revision control before it shows
any pathnames.
This was a real bug, but nobody would ever have noticed, because
the default thing tends to only make sense for git-rev-list, and
git-rev-list didn't use to take pathnames.
- it changes "git-rev-list" to match the other commands that take a mix
of revisions and filenames - it no longer requires the "--" before
filenames (although you still need to do it if a filename could be
confused with a revision name, eg "gitk" in the git archive)
This all just makes for much more pleasant and obvous usage. Just doing a
gitk t/
does the obvious thing: it will show the history as it concerns the "t/"
subdirectory.

git-upload-pack: Support sending multiple ACK messages
The current fetch/upload protocol works like this:
- client sends revs it wants to have via "want" messages
- client sends a flush message (message with len 0)
- client sends revs it has via "have" messages
- after one window (32 revs), a flush is sent
- after each subsequent window, a flush is sent, and an ACK/NAK is received.
(NAK means that server does not have any of the transmitted revs;
ACK sends also the sha1 of the rev server has)
- when the first ACK is received, client sends "done", and does not expect
any further messages
One special case, though:
- if no ACK is received (only NAK's), and client runs out of revs to send,
"done" is sent, and server sends just one more "NAK"
A smarter scheme, which actually has a chance to detect more than one
common rev, would be to send more than just one ACK. This patch implements
the server side of the following extension to the protocol:
- client sends at least one "want" message with "multi_ack" appended, like
"want
1234567890123456789012345678901234567890 multi_ack"
- if the server understands that extension, it will send ACK messages for all
revs it has, not just the first one
- server appends "continue" to the ACK messages like
"ACK
1234567890123456789012345678901234567890 continue"
until it has MAX_HAS-1 revs. In this manner, client knows when to
stop sending revs by checking for the substring "continue" (and
further knows that server understands multi_ack)
In this manner, the protocol stays backwards compatible, since both client
must send "want ... multi_ack" and server must answer with "ACK ...
continue" to enable the extension.
