Export `git_strarray_free` instead of inlining

2011-03-15T23:06:15+00:00

That way non-C bindings can use it.

Use memmove() in gitdirname and gitbasename

2011-03-05T11:58:47+00:00

We cannot make sure that the user doesn't use the same buffer as source
and destination, so write to it using memmove.

Slightly changed the behavior of gitjoinpath() and gitjoinpath_n().

Use the new git__joinpath to build paths in methods

2011-02-09T10:43:19+00:00

The `git__joinpath` function has been changed to use a statically
allocated buffer; we assume the buffer to be 4096 bytes, because fuck
you.

The new method also supports an arbritrary number of paths to join,
which may come in handy in the future.

Some methods which were manually joining paths with `strcpy` now use the
new function, namely those in `index.c` and `refs.c`.

Based on Emeric Fermas' original patch, which was using the old
`git__joinpath` because I'm stupid. Thanks!

Fixed a small issue in git__join_path(). Added tests to exercise git__join_path().

Fix directory/path manipulation methods

2011-02-05T10:42:41+00:00

The `dirname` and `dirbase` methods have been replaced with the Android
implementation, which is actually compilant to some kind of standard.

A new method `topdir` has been added, which returns the topmost
directory in a path.

These changes fix issue #49:

	`gitfo_prettify_dir_path` converts "./.git/" to ".git/", so
	the code at src/repository.c:190 goes out of bounds when
	trying to find the topmost directory.

	The new `git__topdir` method handles this gracefully, and the
	fixed `git__dirname` now returns the proper value for the
	repository's working dir.

	E.g.

		/repo/.git/ ==> working dir '/repo/'
		.git/		==> working dir '.'

Add generic hash function to util.c

2010-12-29T22:31:58+00:00

It's MurmurHash3 slightly edited to make it
cross-platform. Fast and neat.

Use this for hashing strings on hash tables instead
of a full SHA1 hash. It's very fast and well distributed.

Obviously not crypto-secure.

Remove git_errno

2010-12-22T22:15:09+00:00

It was not being used by any methods (only by malloc and calloc), and
since it needs to be TLS, it cannot be exported on DLLs on Windows.

Burn it with fire. The API always returns error codes!
