From: Junio C Hamano Date: Sat, 15 Apr 2006 10:16:46 +0000 (-0700) Subject: Extract "log [diff options]" parser out. X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=f4235f8b2ef875b85ead74ffa199d827f9ee9d8d;p=git.git Extract "log [diff options]" parser out. Merging of the log-tree-opt structure with rev-info structure did not work out very well and it broke things that did not want diff options and/or rev options. This is an alternative approach to define a combined interface that can be used by commands that wants both. The use of it is opt-in to reduce the risk of breaking existing programs. We might want to slurp "setup_revisions() places things in pending objects list" part from Linus's earlier attempt.
