Coda doesn't like cross-directory hardlinks. So try to fall back

Improve sha1 object file writing.
Make it much safer: we write to a temporary file, and then link that
temporary file to the final destination. This avoids all the nasty
races if several people write the same object at the same time.
It should also result in nicer on-disk layout, since it means that
objects all get created in the same subdirectory. That makes a lot
of block allocation algorithms happier, since the objects will now
be allocated from the same zone.

Fix missing '\n' at end of git-cat-file -t output.
Make "cat-file" use "read_object_with_reference()"
This means that you can take a tag object, and do
git-cat-file commit tagname
and it will cat the commit that the tag points to. Or you can
cat the tree that a commit (or tag) points to.
It still gives the old behaviour if you just give it the
original type, ie if you want to see the tag object itself,
you'd do
git-cat-file -t tagname
and you'd get the expected tag output.

If somebody wants it later, we can re-do it, but for now we consider

Add "look up parent" logic for the simple names.
It uses the jit syntax, at least for now. 0-xxxx is the first parent of xxxx,
while 1-xxxx is the second, and so on. You can use just "-xxxx" for the first
parent, but a lot of commands will think that the initial '-' implies a

the SHA1 names, eg just say "HEAD" for the SHA1 pointed to by
the .git/HEAD file etc.

[PATCH] Really fix git-merge-one-file-script this time.
The merge-cache program was updated to pass executable bits when
calling git-merge-one-file-script, but the called script
supplied as an example were not using them carefully.
This patch fixes the following problems in the script:
* When a new file is created in a directory, which is a file in
the work tree, it tried to create leading directory but did
not check for failure from the "mkdir -p" command.
* The script did not check the exit status from the
git-update-cache command at all.
* The parameter "$4" to the script is a file name that can
contain almost any characters, so it must be quoted with
double quotes and also needs to be preceded with -- to mark
it as a non-option when passed to certain commands.
* The chmod command was used with parameter "$6" or "$7" to set
the mode bits. This contradicts with the strategy taken by
checkout-cache, where we honor user's umask and force only
the executable bits. With this patch, it creates a new file
by redirecting into it (thus honoring user's default umask),
and then uses "chmod +x" if we want the resulting file
executable. Without this fix, the merge result becomes 0644
or 0755 for users whose umask is 002 for whom it should
become 0664 or 0775.
* When "$1 -> $2 -> $3" case was not handled, the script did
not say which path it was working on, which was not so useful
when used with the -a option of git-merge-cache.

Rename git core commands to be "git-xxxx" to avoid name clashes.
This also regularizes the make. The source files themselves don't get
the "git-" prefix, because that's just inconvenient. So instead we just
make the rule that "git-xxxx" depends on "xxxx.c", and do that for
all the core programs (ie the old "git-mktag.c" got renamed to just
"mktag.c" to match everything else).
And "show-diff" got renamed to "git-diff-files" while at it, since
that's what it really should be to match the other git-diff-xxx cases.

[PATCH] GIT: Honour SHA1_FILE_DIRECTORY env var in git-pull-script
If you set SHA1_FILE_DIRECTORY to something else than .git/objects
git-pull-script will store the fetched files in a location the rest of

git-prune-script also ignores this setting, but I think this is good,
because pruning a shared tree to fit a single project means throwing

[PATCH] create tar archives of tree on the fly
This is an improved version of tar-tree, a streaming archive creator for
GIT. The major added feature is blocking; all write(2) calls now have a
size of 10240, just as GNU tar (and tape drives) likes them. The
buffering overhead does not seem to degrade performance because most
files in the repositories I tested this with are smaller than 10KB, so
we need fewer system calls.
File names are still restricted to 500 bytes and the archive format
currently only allows for files up to 8GB. Both restrictions can be
lifted if need be with more pax extended headers.
The archive format used is the pax interchange format, i.e. POSIX tar
format. It can be read by (and created with) GNU tar. If I read the
specs correctly tar-tree should now be standards compliant (modulo
bugs).
Because it streams the archive (think ls-tree merged with cat-file),
tar-tree doesn't need to create any temporary files. That makes it
quite fast.
It accepts tree IDs and commit IDs as first parameter. In the latter
case tar-tree tries to get the commit date out of the committer line.
Else all files in the archive are time-stamped with the current time.
An optional second parameter is used as a path prefix for all files in
the archive. Example:
$ tar-tree a2755a80f40e5794ddc20e00f781af9d6320fafb \
linux-2.6.12-rc3 | bzip9 -9 > linux-2.6.12-rc3.tar.bz2

[PATCH] diff-cache buglet
diff-cache attempts to first remove all merge entries before letting the
diff_cache() do its work, but it incorrectly stops after the first
merge-entry it finds.
Fix by just replacing the "break" with a "continue".

[PATCH] Diff-tree-helper take two.
This reworks the diff-tree-helper and show-diff to further make external
diff command interface simpler.
These commands now honor GIT_EXTERNAL_DIFF environment variable which
can point at an arbitrary program that takes 7 parameters:
name file1 file1-sha1 file1-mode file2 file2-sha1 file2-mode
The parameters for an external diff command are as follows:
name this invocation of the command is to emit diff
for the named cache/tree entry.
file1 pathname that holds the contents of the first
file. This can be a file inside the working
tree, or a temporary file created from the blob
object, or /dev/null. The command should not
attempt to unlink it -- the temporary is
unlinked by the caller.
file1-sha1 sha1 hash if file1 is a blob object, or "."
otherwise.
file1-mode mode bits for file1, or "." for a deleted file.
If GIT_EXTERNAL_DIFF environment variable is not set, the
default is to invoke diff with the set of parameters old
show-diff used to use. This built-in implementation honors the
GIT_DIFF_CMD and GIT_DIFF_OPTS environment variables as before.

[PATCH] Introduce diff-tree-helper.
This patch introduces a new program, diff-tree-helper. It reads
output from diff-cache and diff-tree, and produces a patch file.
The diff format customization can be done the same way the
show-diff uses; the same external diff interface introduced by
the previous patch to drive diff from show-diff is used so this
is not surprising.
It is used like the following examples:
$ diff-cache --cached -z <tree> | diff-tree-helper -z -R paths...
$ diff-tree -r -z <tree1> <tree2> | diff-tree-helper -z paths...
- As usual, the use of the -z flag is recommended in the script
to pass NUL-terminated filenames through the pipe between
commands.
- The -R flag is used to generate reverse diff. It does not
matter for diff-tree case, but it is sometimes useful to get
a patch in the desired direction out of diff-cache.
- The paths parameters are used to restrict the paths that
appears in the output. Again this is useful to use with
diff-cache, which, unlike diff-tree, does not take such paths
restriction parameters.

[PATCH] Split external diff command interface to a separate file.
With this patch, the non-core'ish part of show-diff command that
invokes an external "diff" comand to obtain patches is split
into a separate file. The next patch will introduce a new
command, diff-tree-helper, which uses this common diff interface
to format diff-tree and diff-cache output into a patch form.

fsck-cache: show root objects only with "--root"
This makes the default fsck behaviour be quiet for a repository
that doesn't have any problems. Which is good.

fsck-cache: only show tags if asked to do so with "--tags"
Normally we don't care, we just check them for being valid tag
objects.

Add the git-*-script files to the install
Add example "git-tag-script" to show how to create signed tag objects.
Make "fsck" also show what the name of the tag object is, not just
the name of the object it tags.
You need this if you actually want to build up a list of tags.
