Hi all,
Here are my patches to extend Wim's extension. I'm only including in this
bundle those of his that my patches depend on, but you also need at least
some of the others, including Juliusz' patch, to make this actually work.
When included with those, one now can just stick a git directory (or a
symlink to one) in the darcs source and configure --enable-git. I've
verified that darcs changes works with the git repository.
Alas, darcs changes --summary is horribly slow, due to the cost of merging.
Unless we come up with some other trick, we *really* will want to look into
faster commutation tricks (e.g. sorting patches according to what files
they modify, so a commute is cheaper than O(N*M) where N and M are the
number of primitive patches in each of the two patches being commuted.
This is definitely both possible and practical, but there hasn't been a
compelling need to implement the code to do so, which might get a bit
ugly.
I'll be applying this stuff directly to darcs-stable. My current policy is
that git stuff that can't mess up non-git code goes quickly into
darcs-stable (since git isn't ready for prime time anyways, may as well
provide as nice support as possible). Also, build changes go there more
quickly than code changes, since build stuff doesn't get much tested in
darcs-unstable anyways.
David.

* Autoconf support for linking against libgit.a
Allow (actually, require) the user to specify the location of the Git
implementation when including Git support. Attempt to discover whether
Git was compiled to require OpenSSL's implementation of SHA1.
Sun Jul 31 06:56:56 EDT 2005 David Roundy <droundy@abridgegame.org>
* remove the now-unneeded git/.
Sun Jul 31 07:27:40 EDT 2005 David Roundy <droundy@abridgegame.org>
* check for a git/ in current directory (when --enable-git).

David Roundy <droundy@abridgegame.org>**20050723125507
The bug was that we sometimes looked at patches that weren't strictly
necesary. This was because of the concat in get_patches_beyond_tag, which
loses information about tag dependencies. A clean implementation of a
get_extra that accepts a true PatchSet would be a nicer fix (since it might
fix other similar problems), but this fix is also correct and simple.

[replace write_pending with "with_new_pending".
David Roundy <droundy@abridgegame.org>**20050722125725
This patch is basically an extension of Ian's earlier patch that created a
"write_pending_then" function. This one creates two functions,
with_new_pending and add_to_pending.
The idea is that we can't check if a new pending is valid until after we've
updated the pristine cache. But it's possible that the pending patch
itself was lazily generated with get_unrecorded, in which case it's not
safe to modify the pristine cache until after we've written pending. This
new interface makes it much harder to make this kind of mistake. I also
think it's pretty intuitive.

[bugfix, make _darcs/prefs/defaults really override $HOME/.darcs/defaults
Tommy Pettersson <ptp@lysator.liu.se>**20050612174925
Variants of the same flag from the two defaults files where just merged,
and an ALL in the local defaults could not override an explicit command
in the global defaults, as would be expected.

Modified read_conf() so it caches the parsed configuration values

effect of this is that flag names can no longer contain spaces, but
that shouldn't affect anybody.)

Wim Lewis <wiml@hhhh.org>**20050710051424
Unquoted regexp evaluated to 0 or 1, which didn't immediately break the cgi
