d5c7721d58 Git.pm: Add support for subdirectories inside of working copies
This patch adds support for subdirectories inside of working copies;
you can specify them in the constructor either as the Directory
option (it will just get autodetected using rev-parse) or explicitly
using the WorkingSubdir option. This makes Git->repository() do the
exact same path setup and repository lookup as the Git porcelain
does.

This patch also introduces repo_path(), wc_path() and wc_subdir()
accessor methods and wc_chdir() mutator.

This gives the user a way to easily pass options to the command routines.

what shall be done with error output of the called command (most usefully,

8b9150e3e3 Git.pm: Handle failed commands' output
Currently if an external command returns error exit code, a generic exception
is thrown and there is no chance for the caller to retrieve the command's
output.

This patch introduces a Git::Error::Command exception class which is thrown
in this case and contains both the error code and the captured command output.
You can use the new git_cmd_try statement to fatally catch the exception
while producing a user-friendly message.

It also adds command_close_pipe() for easier checking of exit status of
a command we have just a pipe handle of. It has partial forward dependency
on the next patch, but basically only in the area of documentation.

97b16c0674 Git.pm: Better error handling
So far, errors just killed the whole program and in case of an error
inside of libgit it would be totally uncatchable. This patch makes
Git.pm throw standard Perl exceptions instead. In the future we might
subclass Error to Git::Error or something but for now Error::Simple
is more than enough.

5c4082fd68 Add Error.pm to the distribution
I have been thinking about how to do the error reporting the best
way and after scraping various overcomplicated concepts, I have
decided that by far the most elegant way is to throw Error exceptions;
the closest sane alternative is to catch the dies in Git.pm by
enclosing the calls in eval{}s and that's really _quite_ ugly.

The only "small" trouble is that Error.pm turns out sadly not to be
part of the standard distribution, and installation from CPAN is
a bother, especially if you can't install it system-wide. But since
it is very small, I've decided to just bundle it.

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.

My current working state is available all the time at

	http://pasky.or.cz/~xpasky/git-perl/Git.pm

and an irregularily updated API documentation is at

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

0556a11a0d git object hash cleanups
This IMNSHO cleans up the object hashing.

The hash expansion is separated out into a function of its own, the hash
array (and size) names are made more obvious, and the code is generally
made to look a bit more like the object-ref hashing.

It also gets rid of "find_object()" returning an index (or negative
position if no object is found), since that is made redundant by the
simplified object rehashing. The basic operation is now "lookup_object()"
which just returns the object itself.

There's an almost unmeasurable speed increase, but more importantly, I
think the end result is more readable.

6631c73685 revision.c: --full-history fix.
With history simplification, we still show merges that are required
to make the history _complete_, i.e. say that you had:

	  a
	  |
	  b
	 / \
	c   d
	|   |

and neither "a" nor "b" actually changed the file, but both "c" and "d"
did: in this case we have to leave "b" around just because otherwise there
would be no way to show the _relationship_, even if "b" itself doesn't
actually change the tree in any way what-so-ever.

It would make sense to make that further simplification if the
"--parents" flag wasn't present.  In that case the user is
literally asking for a list of commits and is not interested in
the relationship between them.

This patch also fixes a real bug.  Without this patch, the
"--parents --full-history" combination (which you'd get if you
do something like

	gitk --full-history Makefile

or similar) will actually _drop_ merges where all children are identical.
That's wrong in the --full-history case, because it means that the graph
ends up missing lots of entries.

In the process, this also should make

	git-rev-list --full-history Makefile

give just the _true_ list of all commits that changed Makefile (and
properly ignore merges that were identical in one parent), because now
we're not asking for "--parent", so we don't need the unnecessary merge
commits to keep the history together.
