From 5d23e133d23bc9e26d6f23a4d136901e18e6ffba Mon Sep 17 00:00:00 2001 From: Junio C Hamano Date: Mon, 9 Apr 2007 17:01:27 -0700 Subject: Refactor patch-id filtering out of git-cherry and git-format-patch. 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.
