[PATCH] fetch/pull: short-hand notation for remote repositories.
Since pull and fetch are done often against the same remote
repository repeatedly, keeping the URL to pull from along with
the name of the head to use in $GIT_DIR/branches/$name makes a
lot of sense. Adopt that convention from Cogito, and try to be
compatible when possible; storing a partial URL and completing
it with a trailing path may not be understood by Cogito.
While we are at it, fix pulling a tag. Earlier, we updated only
refs/tags/$tag without updating FETCH_HEAD, and called
resolve-script using a stale (or absent) FETCH_HEAD.

Be slightly smarter about git-daemon client shutdown
Shut down connections that haven't even identified themselves as git
clients first. That should get rid of people who just connect to the
port and wait for something to happen.
The cvsimport example in the cvs migration document was still
using the old syntax for target repository after new and
improved cvsimport-script was merged.

Now, not all projects can be as refined as Linux. Before the final 1.0
release, we went through fifteen 0.99 patchfiles, and pl14 alone went
through subreleases 'a' through 'z'. Now _that_ is a release process.
Not to mention the odd-ball releases, like 0.96c+
Sadly, in this day and age of RPM's etc, we have silly limitations, and
I cannot call this release '0.99pl5a or some such awe-inspiring name
just because "rpmbuild" is such a party pooper. So it's just 0.99.1.
Oh well. Aspiring to such greatness as the Linux release numbering is
hubris anyway. You can attain such perfection only once in your life.
And finally what all of this has been leading up to.
The 2 line code change to record who made a tag,
and the 8 line code change to check that we recorded
the tag.
Gosh the error checking is always so much bigger than the code :)
[PATCH] Update git-tag-script to create the .git/refs/tags if it does not already exist
When testing tags I ran into an interesting problem.
git-tag-script dies if .git/refs/tags/ does not exist.
And that directory didn't get created when I build my repository,
so we need to create it if it doesn't exist.

[PATCH] Add git-var a tool for reading interesting git variables.
Sharing code between shell scripts and C is a challenge. The program
git-var allows us to have a set of named values that a shell script can
interrogate and a normal C program can simply call the functions that
compute them. Allowing sharing when computing plain test values.
git-daemon: re-organize code a bit for --inetd flag
Alexey Nezhdanov sent a patch that made git-daemon usable from inetd (ie
where inetd has already done the accept on the new connection, the fork,
and the setup of stdin/stdout). I wanted to organize the thing slightly
differently, though.
Split up "diff_format" into "format" and "line_termination".
This removes the separate "formats" for name and name-with-zero-
termination.
It also removes the difference between HUMAN and MACHINE formats, and
they both become DIFF_FORMAT_RAW, with the difference being just in the
line and inter-filename termination.
... and make git-diff-files use it too. This all _should_ make the
diffcore-pathspec.c phase unnecessary, since the diff'ers now all do the
path matching early interally.
Start using the partial tree reading in "git-diff-cache"
The reason I say "start using" is that we really should also limit the
index checking by name - now we limit the tree object accesses by name,
but we still check the whole index.
Make "git prune" use the "--full" flag to git-fsck-cache
It's too dangerous not to. We need to follow alternate object
directories etc, or we might say something is unreachable just because
we didn't look it up completely.

Oh, well.. FC4 has UTF-8 as the default environment, and I applaud
that, but then it sometimes results in these characters that aren't

[PATCH] clone-pack and clone-script: documentation and add a missing parameter.
While adding the documentation for these two commands, I noticed
that the name of the program on the other end (git-upload-pack)
is already almost configurable but git-clone-pack lacked command
line parameter parsing to actually use anything but default, so
I introduced --exec= like other remote commands while I was at it.

[PATCH] cat-file: be consistent in usage string and documentation.
Now that we have something called tag object, and a notion of
"tags" stored in .git/refs/tags/ directory, the word "tagname"
has become misleading in the usage string. The documentation
already calls that <type>.

Useful for pulling stuff off a dedicated server. Instead of connecting
with ssh or just starting a local pipeline, we connect over TCP to the
other side and try to see if there's a git server listening.
Of course, since I haven't written the git server yet, that will never
happen. But the server really just needs to listen on a port, and
execute a "git-upload-pack" when somebody connects.
(It should read one packet-line, which should be of the format
"git-upload-pack directoryname\n"
and eventually we migth have other commands the server might accept).
git-apply: be a lot more careful when writing files
We write them under another name and rename them to their destination,
so that if something bad happens in the middle, we won't have caused any
bigger harm.
Also, this makes the writing be NFS "intr" safe, and as a side effects
makes sure that if the target is hardlinked (or symlinked) we will have
broken the link.
[PATCH] git-diff-*: --name-only and --name-only-z.
Porcelain layers often want to find only names of changed files,
and even with diff-raw output format they end up having to pick
out only the filename. Support --name-only (and --name-only-z
for xargs -0 and cpio -0 users that want to treat filenames with
embedded newlines sanely) flag to help them.

That way we avoid any confusion with "GNU Interactive Tools", and it's
more descriptive anyway (the rpm documentation talks about how git is
split into a "core" part and an "SCM" part, this makes it clear that
this is the core one).
and it creates a new branch of name <branchname>. If a starting point
is specified, that will be where the branch is created, otherwise it
will be created at the current HEAD.
Make "git checkout" verify that the argument refers to a commit
We still need to create a new branch if it didn't refer to an existing
branch, otherwise our HEAD will continue to point to something totally
different than what we just checked out.
I'll need to think about it. Maybe only do it with "-f" and force it to
the "master" branch?
git-rev-parse: Allow a "zeroth" parent of a commit - the commit itself.
This sounds nonsensical, but it's useful to make sure that the result is
a commit.
For example, "git-rev-parse v2.6.12" will return the _tag_ object for
v2.6.12, but "git-rev-parse v2.6.12^0" will return the _commit_ object
associated with that tag (and v2.6.12^1 will return the first parent).
Also, since the "parent" code will actually parse the commit, this,
together with the "--verify" flag, will verify not only that the result
is a single SHA1, but will also have verified that it's a proper commit
that we can see.
Cut-and-paste dup noticed by Junio. It's not even harmless, since a
match also causes that match to be invalidated, so this made it
impossible to update an existing branch by name.
I'd only tested the case of "ref doesn't exist at all on the other end",
which worked fine.
[PATCH] git-clone-script local optimization tweaks
- When local optimization is used, the variable repo has
already been passed through get_repo_base so there is no need
to check for .git subdirectory in there.

This reverses the order of object lookup, to check pack index first and
then go to the filesystem to find .git/objects/??/ hierarchy.
When most of the objects are packed, this saves quite many stat() calls
and negative dcache entries; while the price this approach has to pay is
negligible, even when most of the objects are outside pack, because
checking pack index file is quite cheap.

[PATCH] Dereference tag repeatedly until we get a non-tag.
When we allow a tag object in place of a commit object, we only
dereferenced the given tag once, which causes a tag that points at a tag
that points at a commit to be rejected. Instead, dereference tag
repeatedly until we get a non-tag.
This patch makes change to two functions:
- commit.c::lookup_commit_reference() is used by merge-base,
rev-tree and rev-parse to convert user supplied SHA1 to that of
a commit.
- rev-list uses its own get_commit_reference() to do the same.
Dereferencing tags this way helps both of these uses.

The location alt_odb[j].name[0..] is filled with ??/?{38} to form a sha1
filename to try, but I was too lazy to allocate a copy, so while
fsck_object_dir() is running for the directory, the filenames ??/?{38}
are filled after NUL (usually and always the location should have '/'),
making them "not found".
git-unpack-objects: show progress report by default
This ends up being very calming for big "git clone"s, since otherwise
you just get very frustrated with a long silence, wondering whether it's
working at all.
Use "-q" to quiet it down.
Now if we could just do the same for the initial "figure out what to
pack" phase, which can also be quite slow if the other end is busy (or
not packed and not in cache)...
If it is fed a commit with more than one leading blank lines,
the sed scripts git-format-patch-script used looped forever.
Using git-stripspace upfront makes the sed script somewhat
simpler to work around this problem.
Also use git-rev-parse so that we can say
$ git-format-patch-script HEAD^^^^

This silently adds the ".git" directory component if needed, so you
don't need to state it explicitly for the source. Also, it turns the
source into an absolute pathname when local, so that you can use
relative pathnames without losing sight of the source when we cd into
the destination.
Teach 'git-send-pack' to send new branches and tags.
The protocol always supported it, but send-pack didn't actually know how
to tell the other side about a new branch/tag.
NOTE! You'll have to name it explicitly on the command line: if you
don't name any branches, git-send-pack will default to the branches that
already exist.
[PATCH] Use sq_quote() to properly quote the parameter to call shell.
This tries to be more lenient to the users and stricter to the
attackers by quoting the input properly for shell safety,
instead of forbidding certain characters from the input.
Things to note:
- We do not quote "prog" parameter (which comes from --exec).
The user should know what he is doing. --exec='echo foo'
will supply the first two parameters to the resulting
command, while --exec="'echo foo'" will give the first
parameter, a single string with a space inside.
- We do not care too much about leaking the sq_quote() output
just before running exec().

Add "git-sh-setup-script" for common git shell script setup
It sets up the normal git environment variables and a few helper
functions (currently just "die()"), and returns ok if it all looks like
a git archive. So use it something like
. git-sh-setup-script || die "Not a git archive"
to make the rest of the git scripts more careful and readable.
I still worry about just quoting things when passing it off to "ssh" or
"sh -c", so I'm being anal. But _, ^ and , are certainly ok and while
both ~ and @ can have speacial meaning to shell/ssh they are benign.
