Subject: [PATCH v2 5/6] commit/revisions: bookkeeping before refactoring
Date: Mon, 17 Sep 2018 21:08:48 -0700 (PDT) [thread overview]
Message-ID: <0e64fc144cf4eb8b15c9e8453cf8af83330930e2.1537243720.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.25.v2.git.gitgitgadget@gmail.com>
From: Derrick Stolee <dstolee@microsoft.com>
There are a few things that need to move around a little before
making a big refactoring in the topo-order logic:
1. We need access to record_author_date() and
compare_commits_by_author_date() in revision.c. These are used
currently by sort_in_topological_order() in commit.c.
2. Moving these methods to commit.h requires adding the author_slab
definition to commit.h.
3. The add_parents_to_list() method in revision.c performs logic
around the UNINTERESTING flag and other special cases depending
on the struct rev_info. Allow this method to ignore a NULL 'list'
parameter, as we will not be populating the list for our walk.
