Edgar Toernig ecee9d9e79 [PATCH] Do date parsing by hand...
...since everything out there is either strange (libc mktime has issues
with timezones) or introduces unnecessary dependencies for people (libcurl).

This goes back to the old date parsing, but moves it out into a file of
its own, and does the "struct tm" to "seconds since epoch" handling by
hand. 

I grepped through the tz-database and it seems there's one "country"
left that has non-60-minute DST: Lord Howe Island.  All others dropped
that before 1970.

tony.luck@intel.com d167f147dc [PATCH] Fix AUTHOR_DATE timezone confusion
This switches git-commit-tree to using curl_getdate() for the
AUTHOR_DATE, and thus fixes the problem with "mktime()" parsing dates in
the local timezone.  It also ends up being more permissive about the
format of the date.

Linus Torvalds a3df180138 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 731ab9ccf2 [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

their temporary files behind.  Also when the external diff
program is killed instead of exiting (this usually happens when

Junio C Hamano 2f97813870 [PATCH] Make diff-cache and friends output more cg-patch friendly.
This changes the way the default arguments to diff are built when
diff-cache and friends are invoked with -p and there is no
GIT_EXTERNAL_DIFF environment variable.  It attempts to be more cg-patch
friendly by:

 - Showing diffs against /dev/null to denote added or removed
   files;

 - Showing file modes for existing files as a comment after the
   diff label.

Unfortunately with this change GIT_DIFF_CMD customization cannot
be supported easily anymore, so it has been dropped.
GIT_DIFF_OPTS customization to change diffs from unified to
context is still there, though.

Junio C Hamano be3cfa85f4 [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.

Junio C Hamano d1df574380 [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.
