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.

Rene Scharfe [Thu, 28 Apr 2005 19:16:43 +0000 (12:16 -0700)]
[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
