From 31609c17251f368584f7b94d44b06194112b4251 Mon Sep 17 00:00:00 2001 From: Rene Scharfe Date: Sun, 2 Jul 2006 01:29:26 +0200 Subject: [PATCH] Add get_merge_bases_clean() Add get_merge_bases_clean(), a wrapper for get_merge_bases() that cleans up after doing its work and make get_merge_bases() NOT clean up. Single-shot programs like git-merge-base can use the dirty and fast version. Also move the object flags used in get_merge_bases() out of the range defined in revision.h. This fixes the "66ae0c77...ced9456a 89719209...262a6ef7" test of the ... operator which is introduced with the next patch.
