453ec4bdf4 libify git-ls-files directory traversal
This moves the core directory traversal and filename exclusion logic
into the general git library, making it available for other users
directly.

If we ever want to do "git commit" or "git add" as a built-in (and we
do), we want to be able to handle most of git-ls-files as a library.

NOTE! Not all of git-ls-files is libified by this.  The index matching
and pathspec prefix calculation is still in ls-files.c, but this is a
big part of it.

051308f6e9 binary patch.
This adds "binary patch" to the diff output and teaches apply
what to do with them.

On the diff generation side, traditionally, we said "Binary
files differ\n" without giving anything other than the preimage
and postimage object name on the index line.  This was good
enough for applying a patch generated from your own repository
(very useful while rebasing), because the postimage would be
available in such a case.  However, this was not useful when the
recipient of such a patch via e-mail were to apply it, even if
the preimage was available.

This patch allows the diff to generate "binary" patch when
operating under --full-index option.  The binary patch follows
the usual extended git diff headers, and looks like this:

	"GIT binary patch\n"
	<length byte><data>"\n"
	...
	"\n"

Each line is prefixed with a "length-byte", whose value is upper
or lowercase alphabet that encodes number of bytes that the data
on the line decodes to (1..52 -- 'A' means 1, 'B' means 2, ...,
'Z' means 26, 'a' means 27, ...).  <data> is 1 or more groups of
5-byte sequence, each of which encodes up to 4 bytes in base85
encoding.  Because 52 / 4 * 5 = 65 and we have the length byte,
an output line is capped to 66 characters.  The payload is the
same diff-delta as we use in the packfiles.

On the consumption side, git-apply now can decode and apply the
binary patch when --allow-binary-replacement is given, the diff
was generated with --full-index, and the receiving repository
has the preimage blob, which is the same condition as it always
required when accepting an "Binary files differ\n" patch.

5010cb5fcc built-in "git grep"
This attempts to set up built-in "git grep" to further reduce
our dependence on the shell, while at the same time optionally
allowing to run grep against object database.  You could do
funky things like these:

	git grep --cached -e pattern	;# grep from index
	git grep -e pattern master	;# or in a rev
	git grep -e pattern master next ;# or in multiple revs
	git grep -e pattern pu^@	;# even like this with an
					;# extension from another topic ;-)
	git grep -e pattern master..next ;# or even from rev ranges
	git grep -e pattern master~20:Documentation
					;# or an arbitrary tree
	git grep -e pattern next:git-commit.sh
        				;# or an arbitrary blob

Right now, it does not understand and/or obey many options grep
should accept, and the pattern must be given with -e option due
to the way the parameter parser is structured, both of which
obviously need to be fixed for usability.

But this is going in the right direction.  The shell script
version is one of the worst Portability offender in the git
barebone Porcelainish; it uses xargs -0 to pass paths around and
shell arrays to sift flags and parameters.

755225de6c git builtin "push"
This adds a builtin "push" command, which is largely just a C'ification of
the "git-push.sh" script.

Now, the reason I did it as a built-in is partly because it's yet another
step on relying less on shell, but it's actually mostly because I've
wanted to be able to push to _multiple_ repositories, and the most obvious
and simplest interface for that would seem be to just have a "remotes"
file that has multiple URL entries.

(For "pull", having multiple entries should either just select the first
one, or you could fall back on the others on failure - your choice).

And quite frankly, it just became too damn messy to do that in shell.
Besides, we actually have a fair amount of infrastructure in C, so it just
wasn't that hard to do.

Of course, this is almost totally untested. It probably doesn't work for
anything but the one trial I threw at it. "Simple" doesn't necessarily
mean "obviously correct".

749864627c Add cache-tree.
The cache_tree data structure is to cache tree object names that
would result from the current index file.

The idea is to have an optional file to record each tree object
name that corresponds to a directory path in the cache when we
run write_cache(), and read it back when we run read_cache().
During various index manupulations, we selectively invalidate
the parts so that the next write-tree can bypass regenerating
tree objects for unchanged parts of the directory hierarchy.

We could perhaps make the cache-tree data an optional part of
the index file, but that would involve the index format updates,
so unless we need it for performance reasons, the current plan
is to use a separate file, $GIT_DIR/index.aux to store this
information and link it with the index file with the checksum
that is already used for index file integrity check.

6973dcaee7 Libify diff-files.
This is the first installment to libify diff brothers.

The updated diff-files uses revision.c::setup_revisions()
infrastructure to parse its command line arguments, which means
the pathname arguments are checked more strictly than before.
The tests are adjusted to separate possibly missing paths from
the rest of arguments with double-dashes, to show the kosher
way.

As Linus pointed out, renaming diff.c to diff-lib.c was simply
stupid, so I am renaming it back.  The new diff-lib.c is to

Linus Torvalds
3443546f6e Use a *real* built-in diff generator
This uses a simplified libxdiff setup to generate unified diffs _without_
doing  fork/execve of GNU "diff".

This has several huge advantages, for example:

Before:

	[torvalds@g5 linux]$ time git diff v2.6.16.. > /dev/null

	real    0m24.818s
	user    0m13.332s
	sys     0m8.664s

After:

	[torvalds@g5 linux]$ time git diff v2.6.16.. > /dev/null

	real    0m4.563s
	user    0m2.944s
	sys     0m1.580s

and the fact that this should be a lot more portable (ie we can ignore all
the issues with doing fork/execve under Windows).

Perhaps even more importantly, this allows us to do diffs without actually
ever writing out the git file contents to a temporary file (and without
any of the shell quoting issues on filenames etc etc).

NOTE! THIS PATCH DOES NOT DO THAT OPTIMIZATION YET! I was lazy, and the
current "diff-core" code actually will always write the temp-files,
because it used to be something that you simply had to do. So this current
one actually writes a temp-file like before, and then reads it into memory
again just to do the diff. Stupid.

But if this basic infrastructure is accepted, we can start switching over
diff-core to not write temp-files, which should speed things up even
further, especially when doing big tree-to-tree diffs.

Now, in the interest of full disclosure, I should also point out a few
downsides:

 - the libxdiff algorithm is different, and I bet GNU diff has gotten a
   lot more testing. And the thing is, generating a diff is not an exact
   science - you can get two different diffs (and you will), and they can
   both be perfectly valid. So it's not possible to "validate" the
   libxdiff output by just comparing it against GNU diff.

 - GNU diff does some nice eye-candy, like trying to figure out what the
   last function was, and adding that information to the "@@ .." line.
   libxdiff doesn't do that.

 - The libxdiff thing has some known deficiencies. In particular, it gets
   the "\No newline at end of file" case wrong. So this is currently for
   the experimental branch only. I hope Davide will help fix it.

That said, I think the huge performance advantage, and the fact that it
integrates better is definitely worth it. But it should go into a
development branch at least due to the missing newline issue.

Technical note: this is based on libxdiff-0.17, but I did some surgery to
get rid of the extraneous fat - stuff that git doesn't need, and seriously
cutting down on mmfile_t, which had much more capabilities than the diff
algorithm either needed or used. In this version, "mmfile_t" is just a
trivial <pointer,length> tuple.

That said, I tried to keep the differences to simple removals, so that you
can do a diff between this and the libxdiff origin, and you'll basically
see just things getting deleted. Even the mmfile_t simplifications are
left in a state where the diffs should be readable.

Apologies to Davide, whom I'd love to get feedback on this all from (I
wrote my own "fill_mmfile()" for the new simpler mmfile_t format: the old
complex format had a helper function for that, but I did my surgery with
the goal in mind that eventually we _should_ just do

	mmfile_t mf;

	buf = read_sha1_file(sha1, type, &size);
	mf->ptr = buf;
	mf->size = size;
	.. use "mf" directly ..

which was really a nightmare with the old "helpful" mmfile_t, and really
is that easy with the new cut-down interfaces).

[ Btw, as any hawk-eye can see from the diff, this was actually generated
  with itself, so it is "self-hosting". That's about all the testing it
  has gotten, along with the above kernel diff, which eye-balls correctly,
  but shows the newline issue when you double-check it with "git-apply" ]

This brings http-push functionality more in line with the ssh/git version,
by borrowing bits from send-pack and rev-list to process refspecs and
revision history in more standard ways.  Also, the status of remote objects
is determined using PROPFIND requests for the object directory rather than
HEAD requests for each object - while it may be less efficient for small
numbers of objects, this approach is able to get the status of all remote
loose objects in a maximum of 256 requests.

This adds a git-rm command which provides convenience similar to

given -f).

Like git-add, git-rm expands the given path names through
git-ls-files. This means it only acts on files listed in the
index. And it does act recursively on directories by default, (no -r
needed as in the case of rm itself). When it recurses, it does not
remove empty directories that are left behind.

3fda8c4cc7 Introducing git-cvsserver -- a CVS emulator for git.
git-cvsserver is highly functional. However, not all methods are implemented,
and for those methods that are implemented, not all switches are implemented.
All the common read operations are implemented, and add/remove/commit are
supported.

Testing has been done using both the CLI CVS client, and the Eclipse CVS
plugin. Most functionality works fine with both of these clients.

Currently git-cvsserver only works over SSH connections, see the
Documentation for more details on how to configure your client. It
does not support pserver for anonymous access but it should not be
hard to implement. Anonymous access will need tighter input validation.

In our very informal tests, it seems to be significantly faster than a real
CVS server.

This utility depends on a version of git-cvsannotate that supports -S and on
DBD::SQLite.

cbfb73d73f Add git-blame, a tool for assigning blame.
I have also been working on a blame program. The algorithm is pretty
much the one described by Junio in his blame.perl. My variant doesn't
handle renames, but it shouldn't be too hard to add that. The output
is minimal, just the line number followed by the commit SHA1.

An interesting observation is that the output from my git-blame and
your git-annotate doesn't match on all files in the git
repository. One example where several lines differ is read-cache.c. I
haven't investigated it further to find out which one is correct.

The code should be considered as a work in progress. It certainly has
a couple of rough edges. The output looks fairly sane on the few files
I have tested it on, but it wouldn't be too surprising if it gets some
cases wrong.

Actually, I got interested in seeing how hard this is, and wrote a simple
first cut at doing a tree-optimized merger.

Let me shout a bit first:

  THIS IS WORKING CODE, BUT BE CAREFUL: IT'S A TECHNOLOGY DEMONSTRATION
  RATHER THAN THE FINAL PRODUCT!

With that out of the way, let me descibe what this does (and then describe
the missing parts).

This is basically a three-way merge that works entirely on the "tree"
level, rather than on the index. A lot of the _concepts_ are the same,
though, and if you're familiar with the results of an index merge, some of
the output will make more sense.

You give it three trees: the base tree (tree 0), and the two branches to
be merged (tree 1 and tree 2 respectively). It will then walk these three
trees, and resolve them as it goes along.

The interesting part is:
 - it can resolve whole sub-directories in one go, without actually even
   looking recursively at them. A whole subdirectory will resolve the same
   way as any individual files will (although that may need some
   modification, see later).
 - if it has a "content conflict", for subdirectories that means "try to
   do a recursive tree merge", while for non-subdirectories it's just a
   content conflict and we'll output the stage 1/2/3 information.
 - a successful merge will output a single stage 0 ("merged") entry,
   potentially for a whole subdirectory.
 - it outputs all the resolve information on stdout, so something like the
   recursive resolver can pretty easily parse it all.

Now, the caveats:
 - we probably need to be more careful about subdirectory resolves. The
   trivial case (both branches have the exact same subdirectory) is a
   trivial resolve, but the other cases ("branch1 matches base, branch2 is
   different" probably can't be silently just resolved to the "branch2"
   subdirectory state, since it might involve renames into - or out of -
   that subdirectory)
 - we do not track the current index file at all, so this does not do the
   "check that index matches branch1" logic that the three-way merge in
   git-read-tree does. The theory is that we'd do a full three-way merge
   (ignoring the index and working directory), and then to update the
   working tree, we'd do a two-way "git-read-tree branch1->result"
 - I didn't actually make it do all the trivial resolve cases that
   git-read-tree does. It's a technology demonstration.

Finally (a more serious caveat):
 - doing things through stdout may end up being so expensive that we'd
   need to do something else. In particular, it's likely that I should
   not actually output the "merge results", but instead output a "merge
   results as they _differ_ from branch1"

However, I think this patch is already interesting enough that people who
are interested in merging trees might want to look at it. Please keep in
mind that tech _demo_ part, and in particular, keep in mind the final
"serious caveat" part.

In many ways, the really _interesting_ part of a merge is not the result,
but how it _changes_ the branch we're merging into. That's particularly
important as it should hopefully also mean that the output size for any
reasonable case is minimal (and tracks what we actually need to do to the
current state to create the final result).

The code very much is organized so that doing the result as a "diff
against branch1" should be quite easy/possible. I was actually going to do
it, but I decided that it probably makes the output harder to read. I
dunno.

Anyway, let's think about this kind of approach.. Note how the code itself
is actually quite small and short, although it's prbably pretty "dense".

As an interesting test-case, I'd suggest this merge in the kernel:

	git-merge-tree $(git-merge-base 4cbf876 7d2babc) 4cbf876 7d2babc

which resolves beautifully (there are no actual file-level conflicts), and
you can look at the output of that command to start thinking about what
it does.

The interesting part (perhaps) is that timing that command for me shows
that it takes all of 0.004 seconds.. (the git-merge-base thing takes
considerably more ;)

The point is, we _can_ do the actual merge part really really quickly.

		Linus

PS. Final note: when I say that it is "WORKING CODE", that is obviously by
my standards. IOW, I tested it once and it gave reasonable results - so it
must be perfect.

Whether it works for anybody else, or indeed for any other test-case, is
not my problem ;)

cf7bb589af git-status -v
This revamps the git-status command to take the same set of
parameters as git commit.  It gives a preview of what is being
committed with that command.  With -v flag, it shows the diff
output between the HEAD commit and the index that would be
committed if these flags were given to git-commit command.

git-commit also acquires -v flag (it used to mean "verify" but
that is the default anyway and there is --no-verify to turn it
off, so not much is lost), which uses the updated git-status -v
to seed the commit log buffer.  This is handy for writing a log
message while reviewing the changes one last time.

Now, git-commit and git-status are internally share the same
implementation.

Unlike previous git-commit change, this uses a temporary index
to prepare the index file that would become the real index file
after a successful commit, and moves it to the real index file
once the commit is actually made.  This makes it safer than the
previous scheme, which stashed away the original index file and
restored it after an aborted commit.

8389b52b2a git-rerere: reuse recorded resolve.
In a workflow that employs relatively long lived topic branches,
the developer sometimes needs to resolve the same conflict over
and over again until the topic branches are done (either merged
to the "release" branch, or sent out and accepted upstream).

This commit introduces a new command, "git rerere", to help this
process by recording the conflicted automerge results and
corresponding hand-resolve results on the initial manual merge,
and later by noticing the same conflicted automerge and applying
the previously recorded hand resolution using three-way merge.

A new option '-c' to diff-tree changes the way a merge commit is

    diff-tree fec9ebf... (from parents)

    diff --combined describe.c

       {
     +      unsigned char sha1[20];
     +      struct commit *cmit;

There are a few things to note about this feature:

 - The '-c' option implies '-p'.  It also implies '-m' halfway
   in the sense that "interesting" merges are shown, but not all
   merges.

 - When a blob matches one of the parents, we do not show a diff
   for that path at all.  For a merge commit, this option shows
   paths with real file-level merge (aka "interesting things").

 - As a concequence of the above, an "uninteresting" merge is
   not shown at all.  You can use '-m' in addition to '-c' to
   show the commit log for such a merge, but there will be no
   combined diff output.

 - Unlike "gitk", the output is monochrome.

A '-' character in the nth column means the line is from the nth
parent and does not appear in the merge result (i.e. removed
from that parent's version).

A '+' character in the nth column means the line appears in the
merge result, and the nth parent does not have that line
(i.e. added by the merge itself or inherited from another
parent).

The above example output shows that the function signature was
changed from either parents (hence two "-" lines and a "++"
line), and "unsigned char sha1[20]", prefixed by a " +", was
inherited from the first parent.

The code as sent to the list was buggy in few corner cases,
which I have fixed since then.

It does not bother to keep track of and show the line numbers
from parent commits, which it probably should.

77cb17e940 Exec git programs without using PATH.
The git suite may not be in PATH (and thus programs such as
git-send-pack could not exec git-rev-list).  Thus there is a need for
logic that will locate these programs.  Modifying PATH is not
desirable as it result in behavior differing from the user's
intentions, as we may end up prepending "/usr/bin" to PATH.

- git C programs will use exec*_git_cmd() APIs to exec sub-commands.
- exec*_git_cmd() will execute a git program by searching for it in
  the following directories:
	1. --exec-path (as used by "git")
	2. The GIT_EXEC_PATH environment variable.
	3. $(gitexecdir) as set in Makefile (default value $(bindir)).
- git wrapper will modify PATH as before to enable shell scripts to
  invoke "git-foo" commands.

Ideally, shell scripts should use the git wrapper to become independent
of PATH, and then modifying PATH will not be necessary.

908e5310b9 Add a "git-describe" command
It shows you the most recent tag that is reachable from a particular
commit is.

Maybe this is something that "git-name-rev" should be taught to do,
instead of having a separate command for it. Regardless, I find it useful.

What it does is to take any random commit, and "name" it by looking up the
most recent commit that is tagged and reachable from that commit. If the
match is exact, it will just print out that ref-name directly. Otherwise
it will print out the ref-name, followed by the 8-character "short SHA".

IOW, with something like Junios current tree, I get:

	[torvalds@g5 git]$ git-describe parent
	refs/tags/v1.0.4-g2414721b

ie the current head of my "parent" branch (ie Junio) is based on v1.0.4,
but since it has a few commits on top of that, it has added the git hash
of the thing to the end: "-g" + 8-char shorthand for the commit
2414721b19.

Doing a "git-describe" on a tag-name will just show the full tag path:

	[torvalds@g5 git]$ git-describe v1.0.4
	refs/tags/v1.0.4

unless there are _other_ tags pointing to that commit, in which case it
will just choose one at random.

This is useful for two things:

 - automatic version naming in Makefiles, for example. We could use it in
   git itself: when doing "git --version", we could use this to give a
   much more useful description of exactly what version was installed.

 - for any random commit (say, you use "gitk <pathname>" or
   "git-whatchanged" to look at what has changed in some file), you can
   figure out what the last version of the repo was. Ie, say I find a bug
   in commit 39ca371c45b04cd50d0974030ae051906fc516b6, I just do:

	[torvalds@g5 linux]$ git-describe 39ca371c45b04cd50d0974030ae051906fc516b6
	refs/tags/v2.6.14-rc4-g39ca371c

   and I now know that it was _not_ in v2.6.14-rc4, but was presumably in
   v2.6.14-rc5.

The latter is useful when you want to see what "version timeframe" a
commit happened in.

release that follows 1.0.0 will not be 1.0.0c as planned, but

Added an AIX clause in the Makefile; that clause likely

4050c0df8e Clean up compatibility definitions.
This attempts to clean up the way various compatibility
functions are defined and used.

 - A new header file, git-compat-util.h, is introduced.  This
   looks at various NO_XXX and does necessary function name
   replacements, equivalent of -Dstrcasestr=gitstrcasestr in the
   Makefile.

 - Those function name replacements are removed from the Makefile.

 - Common features such as usage(), die(), xmalloc() are moved
   from cache.h to git-compat-util.h; cache.h includes
   git-compat-util.h itself.

8e49d50388 C implementation of the 'git' program, take two.
This patch provides a C implementation of the 'git' program and
introduces support for putting the git-* commands in a directory
of their own. It also saves some time on executing those commands
in a tight loop and it prints the currently available git commands
in a nicely formatted list.

The location of the GIT_EXEC_PATH (name discussion's closed, thank gods)
can be obtained by running

	git --exec-path

which will hopefully give porcelainistas ample time to adapt their
heavy-duty loops to call the core programs directly and thus save
the extra fork() / execve() overhead, although that's not really
necessary any more.

The --exec-path value is prepended to $PATH, so the git-* programs
should Just Work without ever requiring any changes to how they call
other programs in the suite.

Some timing values for 10000 invocations of git-var >&/dev/null:
	git.sh: 24.194s
	git.c:   9.044s
	git-var: 7.377s

The git-<tab><tab> behaviour can, along with the someday-to-be-deprecated
git-<command> form of invocation, be indefinitely retained by adding
the following line to one's .bash_profile or equivalent:

	PATH=$PATH:$(git --exec-path)

Experimental libraries can be used by either setting the environment variable
GIT_EXEC_PATH, or by using

	git --exec-path=/some/experimental/exec-path

Relative paths are properly grok'ed as exec-path values.

3299c6f6a8 diff: make default rename detection limit configurable.
A while ago, a rename-detection limit logic was implemented as a
response to this thread:

	http://marc.theaimsgroup.com/?l=git&m=112413080630175

where gitweb was found to be using a lot of time and memory to
detect renames on huge commits.  git-diff family takes -l<num>
flag, and if the number of paths that are rename destination
candidates (i.e. new paths with -M, or modified paths with -C)
are larger than that number, skips rename/copy detection even
when -M or -C is specified on the command line.

This commit makes the rename detection limit easier to use.  You
can have:

	[diff]
		renamelimit = 30

in your .git/config file to specify the default rename detection
limit.  You can override this from the command line; giving 0
means 'unlimited':

	git diff -M -l0

We might want to change the default behaviour, when you do not
have the configuration, to limit it to say 20 paths or so.  This
would also help the diffstat generation after a big 'git pull'.

12aa7456c9 Simplify CFLAGS/DEFINES in Makefile
I think the original intention was to make CFLAGS overridable
from the make command line, but somehow we ended up accumulating
conditional makefile sections that wrongly appends values to
CFLAGs.  These assignments do not work when the user actually
override them from the make command line!

DEFINES are handled the same way; it was seemingly overridable,
but the makefile sections had assignments, which meant
overriding it from the command line broke things.

This simplifies things by limiting the internal futzing to
ALL_CFLAGS, and by removing DEFINES altogether.  Overriding
CFLAGS from the command line should start working with this
change.

Done in 0.99.9
==============

Ports
~~~~~

* Cygwin port [HPA].

* OpenBSD build [Merlyn and others].

Fixes
~~~~~

* clone request over git native protocol from a repository with
  too many refs did not work; this has been fixed.

* git-daemon got safer for kernel.org use [HPA].

* Extended SHA1 parser was not enforcing uniqueness for
  abbreviated SHA1; this has been fixed.

* http transport does not barf on funny characters in URL.

* The ref naming restrictions have been formalized and the
  coreish refuses to create funny refs; we still need to audit
  importers.  See git-check-ref-format(1).

New Features and Commands
~~~~~~~~~~~~~~~~~~~~~~~~~

* .git/config file as a per-repository configuration mechanism,
  and some commands understand it [Linus].  See
  git(7).

* The core.filemode configuration item can be used to make us a
  bit more FAT friendly.  See git(7).

* The extended SHA1 notation acquired Peel-the-onion operator
  ^{type} and ^{}.  See git-rev-parse(1).

* SVN importer [Matthias].  See git-svnimport(1).

* .git/objects/[0-9a-f]{2} directories are created on demand,
  and removed when becomes empty after prune-packed [Linus].

* Filenames output from various commands without -z option are
  quoted when they embed funny characters (TAB and LF) using
  C-style quoting within double-quotes, to match the proposed
  GNU diff/patch notation [me, but many people contributed in
  the discussion].

* git-mv is expected to be a better replacement for git-rename.
  While the latter has two parameter restriction, it acts more
  like the regular 'mv' that can move multiple things to one
  destinatino directory [Josef Weidendorfer].

* git-checkout can take filenames to revert the changes to
  them.  See git-checkout(1)

* The new program git-am is a replacement for git-applymbox that
  has saner command line options and a bit easier to use when a
  patch does not apply cleanly.

* git-ls-remote can show unwrapped onions using ^{} notation, to
  help Cogito to track tags.

* git-merge-recursive backend can merge unrelated projects.

* git-clone over native transport leaves the result packed.

* git-http-fetch issues multiple requests in parallel when
  underlying cURL library supports it [Nick and Daniel].

* git-fetch-pack and git-upload-pack try harder to figure out
  better common commits [Johannes].

* git-read-tree -u removes a directory when it makes it empty.

* git-diff-* records abbreviated SHA1 names of original and
  resulting blob; this sometimes helps to apply otherwise an
  unapplicable patch by falling back to 3-way merge.

* git-format-patch now takes series of from..to rev ranges and
  with '-m --stdout', writes them out to the standard output.
  This can be piped to 'git-am' to implement cheaper
  cherry-picking.

* git-tag takes '-u' to specify the tag signer identity [Linus].

* git-rev-list can take optional pathspecs to skip commits that
  do not touch them (--dense) [Linus].

* Comes with new and improved gitk [Paulus and Linus].

names have the same count of ~'s, take the one whose last number is smaller.

With "--tags", the names are derived only from tags.

With "--stdin", the stdin is parsed, and after every sha1 for which a name
could be found, the name is appended. (Try "git log | git name-rev --stdin".)

f3123c4ab3 pack-objects: Allow use of pre-generated pack.
git-pack-objects can reuse pack files stored in $GIT_DIR/pack-cache
directory, when a necessary pack is found.  This is hopefully useful
when upload-pack (called from git-daemon) is expected to receive
requests for the same set of objects many times (e.g full cloning
request of any project, or updates from the set of heads previous day
to the latest for a slow moving project).

Currently git-pack-objects does *not* keep pack files it creates for
reusing.  It might be useful to add --update-cache option to it,
which would allow it store pack files it created in the pack-cache
directory, and prune rarely used ones from it.

1114b26e8f Add git-mv
It supersedes git-rename by adding functionality to move multiple
files, directories or symlinks into another directory.  It also
provides according documentation.

The implementation renames multiple files, using the arguments from
the command line to produce an array of sources and destinations.  In
a first pass, all requested renames are checked for errors, and
overwriting of existing files is only allowed with '-f'.  The actual
renaming is done in a second pass.  This ensures that any error
condition is checked before anything is changed.

ac1b3d1248 Split up tree diff functions into tree-diff.c library
This makes the tree diff functionality independent of the "git-diff-tree"
program, by splitting the core functionality up into a library file.

This will be needed for when we teach git-rev-list to only follow a
specified set of pathnames, rather than the global revision history.

Most of it is a fairly straightforward code move, but it also involves
some calling convention cleanup, and moving some of the static variables
from diff-tree.c into the options structure.

The actual tree change callback routines also become paramterized by the
diff_options structure, allowing the library functionality to do something
else than just show the diff on stdout.

Right now the only user of this functionality remains git-diff-tree
itself.

e1b10391ea Use git config file for committer name and email info
This starts using the "user.name" and "user.email" config variables if
they exist as the default name and email when committing.  This means
that you don't have to use the GIT_COMMITTER_EMAIL environment variable
to override your email - you can just edit the config file instead.

The patch looks bigger than it is because it makes the default name and
email information non-static and renames it appropriately.  And it moves
the common git environment variables into a new library file, so that
you can link against libgit.a and get the git environment without having
to link in zlib and libcrypt.

In short, most of it is renaming and moving, the real change core is
just a few new lines in "git_default_config()" that copies the user
config values to the new base.

It also changes "git-var -l" to list the config variables.

17712991a5 Add ".git/config" file parser
This is a first cut at a very simple parser for a git config file.

The format of the file is a simple ini-file like thing, with simple
variable/value pairs. You can (and should) make the variables have a
simple single-level scope, ie a valid file looks something like this:

	#
	# This is the config file, and
	# a '#' or ';' character indicates
	# a comment
	#

	; core variables
	[core]
		; Don't trust file modes
		filemode = false

	; Our diff algorithm
	[diff]
		external = "/usr/local/bin/gnu-diff -u"
		renames = true

which parses into three variables: "core.filemode" is associated with the
string "false", and "diff.external" gets the appropriate quoted value.

Right now we only react to one variable: "core.filemode" is a boolean that
decides if we should care about the 0100 (user-execute) bit of the stat
information. Even that is just a parsing demonstration - this doesn't
actually implement that st_mode compare logic itself.

Different programs can react to different config options, although they
should always fall back to calling "git_default_config()" on any config
option name that they don't recognize.

66bf85a462 [PATCH] Add "git-update-ref" to update the HEAD (or other) ref
This is a careful version of the script stuff that currently just
blindly writes HEAD with a new value.

You can use

	git-update-ref HEAD <newhead>

or

	git-update-ref HEAD <newhead> <oldhead>

where the latter version verifies that the old value of HEAD matches
oldhead.

It basically allows a "ref" file to be a symbolic pointer to another ref
file by starting with the four-byte header sequence of "ref:".

More importantly, it allows the update of a ref file to follow these
symbolic pointers, whether they are symlinks or these "regular file
symbolic refs".

NOTE! It follows _real_ symlinks only if they start with "refs/":
otherwise it will just try to read them and update them as a regular file
(ie it will allow the filesystem to follow them, but will overwrite such a
symlink to somewhere else with a regular filename).

In general, using

	git-update-ref HEAD "$head"

should be a _lot_ safer than doing

	echo "$head" > "$GIT_DIR/HEAD"

both from a symlink following standpoint _and_ an error checking
standpoint.  The "refs/" rule for symlinks means that symlinks that point
to "outside" the tree are safe: they'll be followed for reading but not
for writing (so we'll never write through a ref symlink to some other
tree, if you have copied a whole archive by creating a symlink tree).

91063bbc6c Multi-backend merge driver.
The new command 'git merge' takes the current head and one or more
remote heads, with the commit log message for the automated case.

If the heads being merged are simple fast-forwards, it acts the
same way as the current 'git resolve'.  Otherwise, it tries
different merge strategies and takes the result from the one that
succeeded auto-merging, if there is any.

If no merge strategy succeeds auto-merging, their results are
evaluated for number of paths needed for hand resolving, and the
one with the least number of such paths is left in the working
tree.  The user is asked to resolve them by hand and make a
commit manually.

The calling convention from the 'git merge' driver to merge
strategy programs is very simple:

 - A strategy program is to be called 'git-merge-<strategy>'.

 - They take input of this form:

	<common1> <common2> ... '--' <head> <remote1> <remote2>...

   That is, one or more the common ancestors, double dash, the
   current head, and one or more remote heads being merged into
   the current branch.

 - Before a strategy program is called, the working tree is
   matched to the current <head>.

 - The strategy program exits with status code 0 when it
   successfully auto-merges the given heads.  It should do
   update-cache for all the merged paths when it does so -- the
   index file will be used to record the merge result as a
   commit by the driver.

 - The strategy program exits with status code 1 when it leaves
   conflicts behind.  It should do update-cache for all the
   merged paths that it successfully auto-merged, and leave the
   cache entry in the index file as the same as <head> for paths
   it could not auto-merge, and leave its best-effort result
   with conflict markers in the working tree when it does so.

 - The strategy program exists with status code other than 0 or
   1 if it does not handle the given merge at all.

As examples, this commit comes with merge strategies based on
'git resolve' and 'git octopus'.

The reverse patch application using "git apply" sometimes is too
rigid.  Since the user would get used to resolving conflicting merges
by hand during the normal merge experience, using the same machinery
would be more helpful rather than just giving up.

Cherry-picking and reverting are essentially the same operation.
You pick one commit, and apply the difference that commit introduces
to its own commit ancestry chain to the current tree.  Revert applies
the diff in reverse while cherry-pick applies it forward.  They share
the same logic, just different messages and merge direction.

insists that your working tree is clean (no local changes) and matches

whole process is aborted and tries to rewind your working tree is to

The 'git show-branches' command turns out to be reasonably useful,
but painfully slow.  So rewrite it in C, using ideas from merge-base
while enhancing it a bit more.

 - Unlike show-branches, it can take --heads (show me all my
   heads), --tags (show me all my tags), or --all (both).

 - It can take --more=<number> to show beyond the merge-base.

 - It shows the short name for each commit in the extended SHA1
   syntax.

 - It can find merge-base for more than two heads.

Examples:

    $ git show-branch --more=6 HEAD

    is almost the same as "git log --pretty=oneline --max-count=6".

    $ git show-branch --merge-base master mhf misc

    finds the merge base of the three given heads.

    $ git show-branch master mhf misc

    shows logs from the top of these three branch heads, up to their
    common ancestor commit is shown.

    $ git show-branch --all --more=10

    is poor-man's gitk, showing all the tags and heads, and
    going back 10 commits beyond the merge base of those refs.

b05701c5b4 Make CFLAGS overridable from make command line.
This patch renames COPTS to CFLAGS, because it's COPTS that was user
overridable.  Also, -Wall is moved there because it's optional.  What
was CFLAGS is now ALL_CFLAGS, which users should not override.

Defines are added to DEFINES.  Since ALL_CFLAGS is recursively expanded,
it uses the final value of DEFINES.

Implicit rules are made explicit since the implicit rules use CFLAGS
rather than ALL_CFLAGS.  I believe that serious projects should not rely
on implicit rules anyway.  Percent rules are used because they are used
already and because they don't need the .SUFFIXES target.

[jc: in addition to updating the patch for 0.99.4, I fixed up a

b1bf95bba2 [PATCH] Added hook in git-receive-pack
Just before updating a ref,

    $GIT_DIR/hooks/update refname old-sha1 new-sha1

is called if executable.  The hook can decline the ref to be
updated by exiting with a non-zero status, or allow it to be
updated by exiting with a zero status.  The mechanism also
allows e.g sending of a mail with pushed commits on the remote
repository.

Documentation update with an example hook is included.

jc: The credits of the basic idea and initial implementation go
to Josef, but I ended up rewriting major parts of his patch, so
bugs are all mine.  Also I changed the semantics for the hook
from his original version (which were post-update hook) so that
the hook can optionally decline to update the ref, and also can
be used to implement the overall cleanups.  The latter was
primarily to implement a suggestion from Linus that calling
update-server-info should be made optional.

8cc6a08319 [PATCH] Making it easier to find which change introduced a bug
This adds a new "git bisect" command.

 - "git bisect start"
	start bisection search.

 - "git bisect bad <rev>"
	mark some version known-bad (if no arguments, then current HEAD)

 - "git bisect good <revs>..."
	mark some versions known-good (if no arguments, then current HEAD)

 - "git bisect reset <branch>"
	done with bisection search and go back to your work (if
	no arguments, then "master").

The way you use it is:

	git bisect start
	git bisect bad			# Current version is bad
	git bisect good v2.6.13-rc2	# v2.6.13-rc2 was the last version
					# tested that was good

When you give at least one bad and one good versions, it will
bisect the revision tree and say something like:

	Bisecting: 675 revisions left to test after this

and check out the state in the middle. Now, compile that kernel, and boot
it. Now, let's say that this booted kernel works fine, then just do

	git bisect good			# this one is good

which will now say

	Bisecting: 337 revisions left to test after this

and you continue along, compiling that one, testing it, and depending on
whether it is good or bad, you say "git bisect good" or "git bisect bad",
and ask for the next bisection.

Until you have no more left, and you'll have been left with the first bad
kernel rev in "refs/bisect/bad".

Oh, and then after you want to reset to the original head, do a

	git bisect reset

to get back to the master branch, instead of being in one of the bisection
branches ("git bisect start" will do that for you too, actually: it will
reset the bisection state, and before it does that it checks that you're
not using some old bisection branch).

Not really any harder than doing series of "quilt push" and "quilt pop",
now is it?

[jc: This patch is a rework based on what Linus posted to the
     list.  The changes are:

  - The original introduced four separate commands, which was
    three too many, so I merged them into one with subcommands.
    
  - Since the next thing you would want to do after telling it
    "bad" and "good" is always to bisect, this version does it
    automatically for you.

  - I think the termination condition was wrong.  The original
    version checked if the set of revisions reachable from next
    bisection but not rechable from any of the known good ones
    is empty, but if the current bisection was a bad one, this
    would not terminate, so I changed it to terminate it when
    the set becomes a singleton or empty.

  - Removed the use of shell array variable.

the pathnames that got moved (and remember to ignore the files that

Doing the directory case will require a bit more scripting.. Something like

	oldfiles=($(git-ls-files | grep '^$src'))
	newfiles=($(git-ls-files | sed ':^$src: s:^$src:$dst:'))
	mv $src $dst && git-update-cache --add --remove -- "${oldfiles[@]}" "${newfiles[@]}"

8f3f9b09dc [PATCH] Add update-server-info.
The git-update-server-info command prepares informational files
to help clients discover the contents of a repository, and pull
from it via a dumb transport protocols.  Currently, the
following files are produced.

 - The $repo/info/refs file lists the name of heads and tags
   available in the $repo/refs/ directory, along with their
   SHA1.  This can be used by git-ls-remote command running on
   the client side.

 - The $repo/info/rev-cache file describes the commit ancestry
   reachable from references in the $repo/refs/ directory.  This
   file is in an append-only binary format to make the server
   side friendly to rsync mirroring scheme, and can be read by
   git-show-rev-cache command.

 - The $repo/objects/info/pack file lists the name of the packs
   available, the interdependencies among them, and the head
   commits and tags contained in them.  Along with the other two
   files, this is designed to help clients to make smart pull
   decisions.

The git-receive-pack command is changed to invoke it at the end,
so just after a push to a public repository finishes via "git
push", the server info is automatically updated.

In addition, building of the rev-cache file can be done by a
standalone git-build-rev-cache command separately.

Sadly, in this day and age of RPM's etc, we have silly limitations, and

Nico pointed out that having verify_pack.c and verify-pack.c was

and enhances the verification done quite a bit.

 - Built-in sha1_file unpacking knows that a base object of a

   advantage of that fact.

 - Earlier verify-pack command only checked the SHA1 sum for the
   entire pack file and did not look into its contents.  It now
   checks everything idx file claims to have unpacks correctly.

 - It now has a hook to give more detailed information for

This patch also uses the same validation mechanism in fsck-cache
when the --full flag is used.

During normal operation, sha1_file.c verifies that a given .idx
file matches the .pack file by comparing the SHA1 checksum
stored in .idx file and .pack file as a minimum sanity check.
We may further want to check the pack signature and version when
we map the pack, but that would be a separate patch.

Earlier, errors to map a pack file was not flagged fatal but led
to a random fatal error later.  This version explicitly die()s
when such an error is detected.

The latter is partiularly useful to generate a "packed history", ie you
could pack up your old history efficiently, but still have it available

I haven't actually written an unpacker yet, so the end result has not

human-readable ranges.

It's really quite stupid: "a..b" will be converted into "a" and "^b" if
"a" and "b" are valid object pointers.  And the "--default" case will be
used if nothing but flags have been seen, so that you can default to a
certain argument if there are no other ranges.

a3437b8c26 [PATCH] Modify git-rev-list to linearise the commit history in merge order.
This patch linearises the GIT commit history graph into merge order
which is defined by invariants specified in Documentation/git-rev-list.txt.

The linearisation produced by this patch is superior in an objective sense
to that produced by the existing git-rev-list implementation in that
the linearisation produced is guaranteed to have the minimum number of
discontinuities, where a discontinuity is defined as an adjacent pair of
commits in the output list which are not related in a direct child-parent
relationship.

With this patch a graph like this:

	a4 ---
	| \   \
	|  b4 |
	|/ |  |
	a3 |  |
	|  |  |
	a2 |  |
	|  |  c3
	|  |  |
	|  |  c2
	|  b3 |
	|  | /|
	|  b2 |
	|  |  c1
	|  | /
	|  b1
	a1 |
	|  |
	a0 |
	| /
	root

Sorts like this:

	= a4
	| c3
	| c2
	| c1
	^ b4
	| b3
	| b2
	| b1
	^ a3
	| a2
	| a1
	| a0
	= root

Instead of this:

	= a4
	| c3
	^ b4
	| a3
	^ c2
	^ b3
	^ a2
	^ b2
	^ c1
	^ a1
	^ b1
	^ a0
	= root

A test script, t/t6000-rev-list.sh, includes a test which demonstrates
that the linearisation produced by --merge-order has less discontinuities
than the linearisation produced by git-rev-list without the --merge-order
flag specified. To see this, do the following:

	cd t
	./t6000-rev-list.sh
	cd trash
	cat actual-default-order
	cat actual-merge-order

The existing behaviour of git-rev-list is preserved, by default. To obtain
the modified behaviour, specify --merge-order or --merge-order --show-breaks
on the command line.

This version of the patch has been tested on the git repository and also on the linux-2.6
repository and has reasonable performance on both - ~50-100% slower than the original algorithm.

This version of the patch has incorporated a functional equivalent of the Linus' output limiting
algorithm into the merge-order algorithm itself. This operates per the notes associated
with Linus' commit 337cb3fb8d.

This version has incorporated Linus' feedback regarding proposed changes to rev-list.c.
(see: [PATCH] Factor out filtering in rev-list.c)

This version has improved the way sort_first_epoch marks commits as uninteresting.

For more details about this change, refer to Documentation/git-rev-list.txt
and http://blackcubes.dyndns.org/epoch/.

f345b0a066 [PATCH] Add -B flag to diff-* brothers.
A new diffcore transformation, diffcore-break.c, is introduced.

When the -B flag is given, a patch that represents a complete
rewrite is broken into a deletion followed by a creation.  This
makes it easier to review such a complete rewrite patch.

The -B flag takes the same syntax as the -M and -C flags to
specify the minimum amount of non-source material the resulting
file needs to have to be considered a complete rewrite, and
defaults to 99% if not specified.

As the new test t4008-diff-break-rewrite.sh demonstrates, if a
file is a complete rewrite, it is broken into a delete/create
pair, which can further be subjected to the usual rename
detection if -M or -C is used.  For example, if file0 gets
completely rewritten to make it as if it were rather based on
file1 which itself disappeared, the following happens:

    The original change looks like this:

	file0     --> file0' (quite different from file0)
	file1     --> /dev/null

    After diffcore-break runs, it would become this:

	file0     --> /dev/null
	/dev/null --> file0'
	file1     --> /dev/null

    Then diffcore-rename matches them up:

	file1     --> file0'

The internal score values are finer grained now.  Earlier
maximum of 10000 has been raised to 60000; there is no user
visible changes but there is no reason to waste available bits.

8597697458 [PATCH] Update rename/copy similarity estimator.
The second round similarity estimator simply used the size of
the xdelta itself to estimate the extent of damage.  This patch
keeps that logic to detect big insertions to terminate the check
early, but otherwise looks at the generated delta in order to
estimate the extent of edit more accurately.

That allows for a lot more flexibility, and means that if a

52e9578985 [PATCH] Introducing software archaeologist's tool "pickaxe".
This steals the "pickaxe" feature from JIT and make it available
to the bare Plumbing layer.  From the command line, the user
gives a string he is intersted in.

Using the diff-core infrastructure previously introduced, it
filters the differences to limit the output only to the diffs
between <src> and <dst> where the string appears only in one but
not in the other.  For example:

 $ ./git-rev-list HEAD | ./git-diff-tree -Sdiff-tree-helper --stdin -M

would show the diffs that touch the string "diff-tree-helper".

In real software-archaeologist application, you would typically
look for a few to several lines of code and see where that code
came from.

The "pickaxe" module runs after "rename/copy detection" module,
so it even crosses the file rename boundary, as the above
example demonstrates.

427dcb4bca [PATCH] Diff overhaul, adding half of copy detection.
This introduces the diff-core, the layer between the diff-tree
family and the external diff interface engine.  The calls to the
interface diff-tree family uses (diff_change and diff_addremove)
have not changed and will not change.  The purpose of the
diff-core layer is to provide an infrastructure to transform the
set of differences sent from the applications, before sending
them to the external diff interface.

The recently introduced rename detection code has been rewritten
to use the diff-core facility.  When applications send in
separate creates and deletes, matching ones are transformed into
a single rename-and-edit diff, and sent out to the external diff
interface as such.

This patch also enhances the rename detection code further to be
able to detect copies.  Currently this happens only as long as
copy sources appear as part of the modified files, but there
already is enough provision for callers to report unmodified
files to diff-core, so that they can be also used as copy source
candidates.  Extending the callers this way will be done in a
separate patch.

Please see and marvel at how well this works by trying out the
newly added t/t4003-diff-rename-1.sh test script.

d19938ab60 Rename environment variables.
H. Peter Anvin mentioned that using SHA1_whatever as an
environment variable name is not nice and we should instead use
names starting with "GIT_" prefix to avoid conflicts.  Here is
what this patch does:

 * Renames the following environment variables:

    New name                           Old Name

    GIT_AUTHOR_DATE                    AUTHOR_DATE
    GIT_AUTHOR_EMAIL                   AUTHOR_EMAIL
    GIT_AUTHOR_NAME                    AUTHOR_NAME
    GIT_COMMITTER_EMAIL                COMMIT_AUTHOR_EMAIL
    GIT_COMMITTER_NAME                 COMMIT_AUTHOR_NAME
    GIT_ALTERNATE_OBJECT_DIRECTORIES   SHA1_FILE_DIRECTORIES
    GIT_OBJECT_DIRECTORY               SHA1_FILE_DIRECTORY

 * Introduces a compatibility macro, gitenv(), which does an
   getenv() and if it fails calls gitenv_bc(), which in turn
   picks up the value from old name while giving a warning about
   using an old name.

 * Changes all users of the environment variable to fetch
   environment variable with the new name using gitenv().

 * Updates the documentation and scripts shipped with Linus GIT
   distribution.

The transition plan is as follows:

 * We will keep the backward compatibility list used by gitenv()
   for now, so the current scripts and user environments
   continue to work as before.  The users will get warnings when
   they have old name but not new name in their environment to
   the stderr.

 * The Porcelain layers should start using new names.  However,
   just in case it ends up calling old Plumbing layer
   implementation, they should also export old names, taking
   values from the corresponding new names, during the
   transition period.

 * After a transition period, we would drop the compatibility
   support and drop gitenv().  Revert the callers to directly
   call getenv() but keep using the new names.

   The last part is probably optional and the transition
   duration needs to be set to a reasonable value.

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 \

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.

e74f8f6aa7 Add "diff-cache" helper program to compare a tree (or commit) with
the current cache state and/or working directory.

Very useful to see what has changed since the last commit, either in
the index file or in the whole working directory.

Also very possibly very buggy. Matching the two up is not entirely
trivial.

c9823a427a Add stupid "git export" thing, which can export a git archive
as a set of patches and commentary.

You'd want something like this if you are tracking a git archive
in another SCM format. Notably, we want something like that for
BK users.

0fcfd160b0 Split up read-cache.c into more logical clumps.
Do the usage and error reporting in "usage.c", and the sha1 file
accesses in "sha1_file.c".

Small, nice, easily separated parts. Good.

0a02ce72d9 Clean up the Makefile a bit.
This introduces the concept of git "library" objects that
the real programs use, and makes it easier to add such things
to a "libgit.a".

This will also make it trivial to split the current "read-cache.o"
into more aptly named pieces (it does a lot more than just read
the index file).

Not pretty, but it's half-way functional.

6683463ed6 Do a very simple "merge-base" that finds the most recent common
parent of two commits.

The question of "best" commit can probably be tweaked almost arbitrarily.
In particular, trying to take things like how big the tree differences
are into account migt be a good idea. This one is just very simple.

2fbdd13174 Remove "merge-tree.c"
It's there in the history if somebody wants to resurrect it, but it

bdd4da595a [PATCH] Make nsec checking optional
The nsec field of ctime/mtime is now checked only with -DNSEC defined during
compilation. nsec acts broken since it is stored in the icache but apparently
just gets to zero when flushed to filesystem not supporting it (e.g. ext3),
creating illusions of false changes. At least that's my impression.

ls-tree tool provides just a way to export the binary tree objects

It's quite fast when the commit-objects are cached, but since
