If MPL isn't ok for X11, then we'd need to make sure that even the
silliest Mozilla crud has been rewritten. There really isn't much, but
hey, the _history_ is based on the mozilla code, and who knows - the
'blk_SHA_CTX' struct has things like the fields in the same order as the
Mozilla equivalent, for all those historical reasons.
(Heh. Looking at that, I probably should move the 'size' field first,
since that would have different alignment rules, and the struct would be
more tightly packed that way, and initialize better).
Afaik, none of the actual code remains (the mozilla SHA1 thing did the
wrong thing for performance even for just the final bytes, and did those a
byte at a time etc, so I rewrote even the trivial SHA1_Final parts).
Of course, maybe the Mozilla people would be interested in taking my
faster version, and say that the new-BSD license is ok, and make everybody
happy. The only listed author for the Mozilla SHA1 is Paul Kocher. I added
him to the Cc.
Paul, for your information, we're talking about a faster rewritten "mostly
portable" SHA1 routines that you can find at
http://git.kernel.org/?p=git/git.git;a=tree;f=block-sha1;hb=pu
(follow the "blob" pointers to see sha1.c and sha1.h). I don't know if
you're active with Mozilla/Firefox or whether you even care, but you seem
to be the logical choice of person to ask.
I contacted Paul in february this year to get permission to use the mozilla
sha1 code for libgit2. His reply then was:
"I'm not sure which version the diffs are relative to, so I haven't reviewed them.
It's fine to distribute under BSD, GPL, or LGPL, however."
I also got explicit permission to relicense it under GPLv2 with the gcc exception.
I added the mail-address I used to contact him to CC as well. Sorry if you get
this twice, Paul.
Naturally, I'd like to use the faster version for libgit2 as well. The people
who Linus listed as contributors earlier (Brandon Casy, Linus, Junio and Nicolas
Pitre) have already consented to relicense their git contributions for libgit2
use. If anyone would like to revoke that consent for this code, speak now please,
or I'll patch it into libgit2 as well.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
