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.

[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-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.

16 years ago[PATCH] Introduce diff-tree-helper.

[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.
