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].

git-upload-pack: Support the multi_ack protocol
This implements three things (trying very hard to be backwards
compatible):
It sends the "multi_ack" capability via the mechanism proposed by
Sergey Vlasov.
When the client sends "multi_ack" with at least one "want", multi_ack
is enabled.
When multi_ack is enabled, "continue" is appended to each "ACK" until
either the server can not store more refs, or "done" is received.
In contrast to the original protocol, as long as "continue" is sent,
flushes are answered by a "NAK" (not just until an "ACK" was sent),
and if "continue" was sent at least once, the last message is an
"ACK" without "continue".

Subject: [PATCH] git-fetch-pack: Do not use git-rev-list
The code used to call git-rev-list to enumerate the local revisions.
A disadvantage of that method was that git-rev-list, lacking a
control apart from the command line, would happily enumerate
ancestors of acknowledged common commits, which was just taking
unnecessary bandwidth.
Therefore, do not use git-rev-list on the fetching side, but rather
construct the list on the go. Send the revisions starting from the
local heads, ignoring the revisions known to be common.

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.

Create object subdirectories on demand (phase II)
This removes the unoptimization. The previous round does not mind
missing fan-out directories, but still makes sure they exist, lest
older versions choke on a repository created/packed by it.
This round does not play that nicely anymore -- empty fan-out
directories are not created by init-db, and will stay removed by
prune-packed. The prune command also removes empty fan-out directories.

[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.

With "--tags", the names are derived only from tags.
With "--stdin", the stdin is parsed, and after every sha1 for which a name

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.

a first pass, all requested renames are checked for errors, and
overwriting of existing files is only allowed with '-f'. The actual
renaming is done in a second pass. This ensures that any error

Silence confusing and false-positive curl error message
git-http-fetch spits out curl 404 error message when unable to fetch an object,
but that's confusing since no error really happened and the object is usually
found in a pack it tries right after that. And if the object still cannot be
retrieved, it will say another error message anyway. OTOH other HTTP errors
(403 etc) are likely fatal and the user should be still informed about them.

git-rev-list: add "--dense" flag
This is what the recent git-rev-list changes have all been gearing up for.
When we use a path filter to git-rev-list, the new "--dense" flag asks
git-rev-list to compress the history so that it _only_ contains commits
that change files in the path filter. It also rewrites the parent
information so that tools like "gitk" will see the result as a dense
history tree.
For example, on the current kernel archive:
[torvalds@g5 linux]$ git-rev-list HEAD | wc -l
9904
[torvalds@g5 linux]$ git-rev-list HEAD -- kernel | wc -l
5442
[torvalds@g5 linux]$ git-rev-list --dense HEAD -- kernel | wc -l
356
which shows that while we have almost ten thousand commits, we can prune
down the work to slightly more than half by only following the merges
that are interesting. But further, we can then compress the history to
just 356 entries that actually make changes to the kernel subdirectory.
To see this in action, try something like
gitk --dense -- gitk
to see just the history that affects gitk. Or, to show that true
parallel development still remains parallel, do
gitk --dense -- daemon.c
which shows some parallel commits in the current git tree.

Teach git-rev-list to follow just a specified set of files
This is the first cut at a git-rev-list that knows to ignore commits that
don't change a certain file (or set of files).
NOTE! For now it only prunes _merge_ commits, and follows the parent where
there are no differences in the set of files specified. In the long run,
I'd like to make it re-write the straight-line history too, but for now
the merge simplification is much more fundamentally important (the
rewriting of straight-line history is largely a separate simplification
phase, but the merge simplification needs to happen early if we want to
optimize away unnecessary commit parsing).
If all parents of a merge change some of the files, the merge is left as
is, so the end result is in no way guaranteed to be a linear history, but
it will often be a lot /more/ linear than the full tree, since it prunes
out parents that didn't matter for that set of files.
As an example from the current kernel:
[torvalds@g5 linux]$ git-rev-list HEAD | wc -l
9885
[torvalds@g5 linux]$ git-rev-list HEAD -- Makefile | wc -l
4084
[torvalds@g5 linux]$ git-rev-list HEAD -- drivers/usb | wc -l
5206
and you can also use 'gitk' to more visually see the pruning of the
history tree, with something like
gitk -- drivers/usb
showing a simplified history that tries to follow the first parent in a
merge that is the parent that fully defines drivers/usb/.

Split up tree diff functions into tree-diff.c library
This makes the tree diff functionality independent of the "git-diff-tree"
program, by splitting the core functionality up into a library file.
This will be needed for when we teach git-rev-list to only follow a
specified set of pathnames, rather than the global revision history.
Most of it is a fairly straightforward code move, but it also involves
some calling convention cleanup, and moving some of the static variables
from diff-tree.c into the options structure.
The actual tree change callback routines also become paramterized by the
diff_options structure, allowing the library functionality to do something
else than just show the diff on stdout.
Right now the only user of this functionality remains git-diff-tree
itself.

Allow git-merge not to commit.
Martin Langhoff wants to use git-merge from outside git-pull and wants
to do further processing; for this, he wants git-merge no to commit
even when it cleanly merges. I think other script writers would want
something like that as well, so here it is.
Instead of the "merge commit message" parameter (which usually is made
for you by "git-pull" which calls this command), you pass an empty
string to it. Then it will not update your HEAD -- you can do whatever
you want with the resulting index file, which contains the merge results.
