* diff_setup_done(): return voidThomas Rast2012-08-031-2/+1
| | | | | | | | | | | | | | | | | diff_setup_done() has historically returned an error code, but lost the last nonzero return in 943d5b7 (allow diff.renamelimit to be set regardless of -M/-C, 2006-08-09). The callers were in a pretty confused state: some actually checked for the return code, and some did not. Let it return void, and patch all callers to take this into account. This conveniently also gets rid of a handful of different(!) error messages that could never be triggered anyway. Note that the function can still die().

* Refactor patch-id filtering out of git-cherry and git-format-patch.Junio C Hamano2007-04-111-0/+192
This implements the patch-id computation and recording library, patch-ids.c, and rewrites the get_patch_ids() function used in cherry and format-patch to use it, so that they do not pollute the object namespace. Earlier code threw non-objects into the in-core object database, and hoped for not getting bitten by SHA-1 collisions. While it may be practically Ok, it still was an ugly hack.
