18b0fc1ce1 Git.pm: Kill Git.xs for now
This patch removes Git.xs from the repository for the time being. This
should hopefully enable Git.pm to finally make its way to master.

Git.xs is not going away forever. When the Git libification makes some
progress, it will hopefully return (but most likely as an optional
component, due to the portability woes) since the performance boosts are
really important for applications like Gitweb or Cogito. It needs to go
away now since it is not really reliable in case you use it for several
repositories in the scope of a single process, and that is not possible
to fix without some either very ugly or very intrusive core changes.

Rest in peace. (While you can.)

83b5d2f5b0 builtin-grep: make pieces of it available as library.
This makes three functions and associated option structures from
builtin-grep available from other parts of the system.

 * options to drive built-in grep engine is stored in struct
   grep_opt;

 * pattern strings and extended grep expressions are added to
   struct grep_opt with append_grep_pattern();

 * when finished calling append_grep_pattern(), call
   compile_grep_patterns() to prepare for execution;

 * call grep_buffer() to find matches in the in-core buffer.

This also adds an internal option "status_only" to grep_opt,
which suppresses any output from grep_buffer().  Callers of the
function as library can use it to check if there is a match
without producing any output.

e1e22e37f4 Start handling references internally as a sorted in-memory list
This also adds some very rudimentary support for the notion of packed
refs.  HOWEVER! At this point it isn't used to actually look up a ref
yet, only for listing them (ie "for_each_ref()" and friends see the
packed refs, but none of the other single-ref lookup routines).

Note how we keep two separate lists: one for the loose refs, and one for
the packed refs we read. That's so that we can easily keep the two apart,
and read only one set or the other (and still always make sure that the
loose refs take precedence).

[ From this, it's not actually obvious why we'd keep the two separate
  lists, but it's important to have the packed refs on their own list
  later on, when I add support for looking up a single loose one.

  For that case, we will want to read _just_ the packed refs in case the
  single-ref lookup fails, yet we may end up needing the other list at
  some point in the future, so keeping them separated is important ]

358ddb62cf Add "git show-ref" builtin command
It's kind of like "git peek-remote", but works only locally (and thus
avoids the whole overhead of git_connect()) and has some extra
verification features.

For example, it allows you to filter the results, and to choose whether
you want the tag dereferencing or not. You can also use it to just test
whether a particular ref exists.

For example:

	git show-ref master

will show all references called "master", whether tags or heads or
anything else, and regardless of how deep in the reference naming
hierarchy they are (so it would show "refs/heads/master" but also
"refs/remote/other-repo/master").

When using the "--verify" flag, the command requires an exact ref path:

	git show-ref --verify refs/heads/master

will only match the exact branch called "master".

If nothing matches, show-ref will return an error code of 1, and in the
case of verification, it will show an error message.

For scripting, you can ask it to be quiet with the "--quiet" flag, which
allows you to do things like

	git-show-ref --quiet --verify -- "refs/heads/$headname" ||
		echo "$headname is not a valid branch"

to check whether a particular branch exists or not (notice how we don't
actually want to show any results, and we want to use the full refname for
it in order to not trigger the problem with ambiguous partial matches).

To show only tags, or only proper branch heads, use "--tags" and/or
"--heads" respectively (using both means that it shows tags _and_ heads,
but not other random references under the refs/ subdirectory).

To do automatic tag object dereferencing, use the "-d" or "--dereference"
flag, so you can do

	git show-ref --tags --dereference

to get a listing of all tags together with what they dereference.

39345a216f Add git-upload-archive
This command implements the git archive protocol on the server
side. This command is not intended to be used by the end user.
Underlying git-archive command line options are sent over the
protocol from "git-archive --remote=...", just like upload-tar
currently does with "git-tar-tree=...".

As for "git-archive" command implementation, this new command
does not execute any existing "git-{tar,zip}-tree" but rely
on the archive API defined by "git-archive" patch. Hence we
get 2 good points:

 - "git-archive" and "git-upload-archive" share all option
   parsing code.

 - All kind of git-upload-{tar,zip} can be deprecated.

4df096a5ca Add git-archive
git-archive is a command to make TAR and ZIP archives of a git tree.
It helps prevent a proliferation of git-{format}-tree commands.

Instead of directly calling git-{tar,zip}-tree command, it defines
a very simple API, that archiver should implement and register in
"git-archive.c". This API is made up by 2 functions whose prototype
is defined in "archive.h" file.

 - The first one is used to parse 'extra' parameters which have
   signification only for the specific archiver. That would allow
   different archive backends to have different kind of options.

 - The second one is used to ask to an archive backend to build
   the archive given some already resolved parameters.

The main reason for making this API is to avoid using
git-{tar,zip}-tree commands, hence making them useless. Maybe it's
time for them to die ?

It also implements remote operations by defining a very simple
protocol: it first sends the name of the specific uploader followed
the repository name (git-upload-tar git://example.org/repo.git).
Then it sends options. It's done by sending a sequence of one
argument per packet, with prefix "argument ", followed by a flush.

The remote protocol is implemented in "git-archive.c" for client
side and is triggered by "--remote=<repo>" option. For example,
to fetch a TAR archive in a remote repo, you can issue:

$ git archive --format=tar --remote=git://xxx/yyy/zzz.git HEAD

We choose to not make a new command "git-fetch-archive" for example,
avoind one more GIT command which should be nice for users (less
commands to remember, keeps existing --remote option).

make sure messages from processes do net get mixed up in
the middle.

e4fbbfe9ec Add git-zip-tree
In the Windows world ZIP files are better supported than tar files.
Windows even includes built-in support for ZIP files nowadays.

git-zip-tree is similar to git-tar-tree; it creates ZIP files out of
git trees.  It stores the commit ID (if available) in a ZIP file comment
which can be extracted by unzip.

There's still quite some room for improvement: this initial version
supports no symlinks, calls write() way too often (three times per file)
and there is no unit test.

7230e6d042 Add write_or_die(), a helper function
The little helper write_or_die() won't come back with bad news about
full disks or broken pipes.  It either succeeds or terminates the
program, making additional error handling unnecessary.

This patch adds the new function and uses it to replace two similar
ones (the one in tar-tree originally has been copied from cat-file
btw.).  I chose to add the fd parameter which both lacked to make
write_or_die() just as flexible as write() and thus suitable for
lib-ification.

There is a regression: error messages emitted by this function don't
show the program name, while the replaced two functions did.  That's
acceptable, I think; a lot of other functions do the same.

f754fa9c54 builtins: Makefile clean-up
This cleans up the build procedure for built-in commands by:

 - generating mostly redundant definition of BUILT_INS from
   BUILTIN_OBJS in the Makefile,
 - renaming a few files to make the above possible, and
 - sorting the built-in command table in git.c.

It might be a good idea to binary search (or perfect hash) the built-in
command table, but that can be done later when somebody feels like.

Configuration will first be taken from variables inside the gitweb.cgi

6d297f8137 Status update on merge-recursive in C
This is just an update for people being interested. Alex and me were
busy with that project for a few days now. While it has progressed nicely,
there are quite a couple TODOs in merge-recursive.c, just search for "TODO".

For impatient people: yes, it passes all the tests, and yes, according
to the evil test Alex did, it is faster than the Python script.

But no, it is not yet finished. Biggest points are:

- there are still three external calls
- in the end, it should not be necessary to write the index more than once
  (just before exiting)
- a lot of things can be refactored to make the code easier and shorter

BTW we cannot just plug in git-merge-tree yet, because git-merge-tree
does not handle renames at all.

This patch is meant for testing, and as such,

- it compile the program to git-merge-recur
- it adjusts the scripts and tests to use git-merge-recur instead of
  git-merge-recursive
- it provides "TEST", a script to execute the tests regarding -recursive
- it inlines the changes to read-cache.c (read_cache_from(), discard_cache()
  and refresh_cache_entry())

ba84a797e7 builtin "git prune"
This actually removes the objects to be pruned, unless you specify "-n"
(at which point it will just tell you which files it would prune).

This doesn't do the pack-file pruning that the shell-script used to do,
but if somebody really wants to, they could add it easily enough. I wonder
how useful it is, though, considering that "git repack -a -d" is just a
lot more efficient and generates a better end result.

6fcca938b0 Use $GITPERLLIB instead of $RUNNING_GIT_TESTS and centralize @INC munging
This makes the Git perl scripts check $GITPERLLIB instead of
$RUNNING_GIT_TESTS, which makes more sense if you are setting up your shell
environment to use a non-installed Git instance.

It also weeds out the @INC munging from the individual scripts and makes
Makefile add it during the .perl files processing, so that we can change
just a single place when we modify this shared logic. It looks ugly in the
scripts, too. ;-)

And instead of doing arcane things with the @INC array, we just do 'use lib'
instead, which is essentialy the same thing anyway.

I first want to do three separate patches but it turned out that it's quite
a lot neater when bundled together, so I hope it's ok.

b1edc53d06 Introduce Git.pm (v4)
This patch introduces a very basic and barebone Git.pm module
with a sketch of how the generic interface would look like;
most functions are missing, but this should give some good base.
I will continue expanding it.

Most desirable now is more careful error reporting, generic_in() for feeding
input to Git commands and the repository() constructor doing some poking
with git-rev-parse to get the git directory and subdirectory prefix.
Those three are basically the prerequisities for converting git-mv.
I will send them as follow-ups to this patch.

Currently Git.pm just wraps up exec()s of Git commands, but even that
is not trivial to get right and various Git perl scripts do it in
various inconsistent ways. In addition to Git.pm, there is now also
Git.xs which provides barebone Git.xs for directly interfacing with
libgit.a, and as an example providing the hash_object() function using
libgit.

This adds the Git module, integrates it to the build system and as
an example converts the git-fmt-merge-msg.perl script to it (the result
is not very impressive since its advantage is not quite apparent in this
one, but I just picked up the simplest Git user around).

Compared to v3, only very minor things were fixed in this patch (some
whitespaces, a missing export, tiny bug in git-fmt-merge-msg.perl);
at first I wanted to post them as a separate patch but since this
is still only in pu, I decided that it will be cleaner to just resend
the patch.

556677144b autoconf: Use autoconf to write installation directories to config.mak.autogen
This is beginning of patch series introducing installation configuration
using autoconf (and no other autotools) to git. The idea is to generate
config.mak.autogen using ./configure (generated from configure.ac by running
autoconf) from config.mak.in, so one can use autoconf as an _alternative_ to
ordinary Makefile, and creating one's own config.mak. Local settings in
config.mak override generated settings in config.mak.autogen

This patch includes minimal configure.ac and config.mak.in, so one can set
installation directories using autoconf generated ./configure script
e.g. ./configure --prefix=/usr

0c7993839b Improved three-way blob merging code
This fleshes out the code that generates a three-way merge of a set of
blobs.

It still actually does the three-way merge using an external executable
(ie just calling "merge"), but the interfaces have been cleaned up a lot
and are now fully based on the 'mmfile_t' interface, so if libxdiff were
to ever grow a compatible three-way-merge, it could probably be directly
plugged in.

It also uses the previous XDL_EMIT_COMMON functionality extension to
libxdiff to generate a made-up base file for the merge for the case where
no base file previously existed. This should be equivalent to what we
currently do in git-merge-one-file.sh:

	diff -u -La/$orig -Lb/$orig $orig $src2 | git-apply --no-add

except it should be much simpler and can be done using the direct libxdiff
interfaces.

855419f764 Add specialized object allocator
This creates a simple specialized object allocator for basic
objects.

This avoids wasting space with malloc overhead (metadata and
extra alignment), since the specialized allocator knows the
alignment, and that objects, once allocated, are never freed.

It also allows us to track some basic statistics about object
allocations. For example, for the mozilla import, it shows
object usage as follows:

     blobs:   627629 (14710 kB)
     trees:  1119035 (34969 kB)
   commits:   196423  (8440 kB)
      tags:     1336    (46 kB)

and the simpler allocator shaves off about 2.5% off the memory
footprint off a "git-rev-list --all --objects", and is a bit
faster too.

[ Side note: this concludes the series of "save memory in object storage".
  The thing is, there simply isn't much more to be saved on the objects.

  Doing "git-rev-list --all --objects" on the mozilla archive has a final
  total RSS of 131498 pages for me: that's about 513MB. Of that, the
  object overhead is now just 56MB, the rest is going somewhere else (put
  another way: the fact that this patch shaves off 2.5% of the total
  memory overhead, considering that objects are now not much more than 10%
  of the total shows how big the wasted space really was: this makes
  object allocations much more memory- and time-efficient).

  I haven't looked at where the rest is, but I suspect the bulk of it is
  just the pack-file loading. It may be that we should pack the tree
  objects separately from the blob objects: for git-rev-list --objects, we
  don't actually ever need to even look at the blobs, but since trees and
  blobs are interspersed in the pack-file, we end up not being dense in
  the tree accesses, so we end up looking at more pages than we strictly
  need to.

  So with a 535MB pack-file, it's entirely possible - even likely - that
  most of the remaining RSS is just the mmap of the pack-file itself. We
  don't need to map in _all_ of it, but we do end up mapping a fair
  amount. ]

3e4339e6f9 Remove "refs" field from "struct object"
This shrinks "struct object" to the absolutely minimal size possible.
It now contains /only/ the object flags and the SHA1 hash name of the
object.

The "refs" field, which is really needed only for fsck, is maintained in
a separate hashed lookup-table, allowing all normal users to totally
ignore it.

This helps memory usage, although not as much as I hoped: it looks like
the allocation overhead of malloc (and the alignment constraints in
particular) means that while the structure size shrinks, the actual
allocation overhead mostly does not.

[ That said: memory usage is actually down, but not as much as it should
  be: I suspect just one of the object types actually ended up shrinking
  its effective allocation size.

  To get to the next level, we probably need specialized allocators that
  don't pad the allocation more than necessary. ]

The separation makes for some code cleanup, though, and makes the ref
tracking that fsck wants a clearly separate thing.

d9b814cc97 Add builtin "git rm" command
This changes semantics very subtly, because it adds a new atomicity
guarantee.

In particular, if you "git rm" several files, it will now do all or
nothing. The old shell-script really looped over the removed files one by
one, and would basically randomly fail in the middle if "-f" was used and
one of the files didn't exist in the working directory.

This C builtin one will not re-write the index after each remove, but
instead remove all files at once. However, that means that if "-f" is used
(to also force removal of the file from the working directory), and some
files have already been removed from the workspace, it won't stop in the
middle in some half-way state like the old one did.

So what happens is that if the _first_ file fails to be removed with "-f",
we abort the whole "git rm". But once we've started removing, we don't
leave anything half done. If some of the other files don't exist, we'll
just ignore errors of removal from the working tree.

This is only an issue with "-f", of course.

I think the new behaviour is strictly an improvement, but perhaps more
importantly, it is _different_. As a special case, the semantics are
identical for the single-file case (which is the only one our test-suite
seems to test).

The other question is what to do with leading directories. The old "git
rm" script didn't do anything, which is somewhat inconsistent. This one
will actually clean up directories that have become empty as a result of
removing the last file, but maybe we want to have a flag to decide the
behaviour?

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.

("log", "show" and "whatchanged"), and "builtin-help.c" for the
informational commands (usage printing and "help" and "version").

This just makes things easier to read, I find.

2006-03-25 17:44:01 -08:00
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" ]

by borrowing bits from send-pack and rev-list to process refspecs and

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.

Like git-add, git-rm expands the given path names through

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

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.

       {
     +      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.

Minor fixes.

Starting from this one I won't be touching debian/ directory
since the official maintainer seems to be reasonably quick to
package up things.  The packaging procedure used there seems to
be quite different from what I have, so I'd like to avoid
potential confusion and reduce work by the official maintainer
and myself.

e99fcf96de git-format-patch should show the correct version
We want to record the version of the tools the patch was generated with.
While these tools could be rebuilt, git-format-patch stayed the same and
report the wrong version.
