Subject: [PATCH v4 09/10] commit-reach: use corrected commit dates in paint_down_to_common()
Date: Wed, 07 Oct 2020 14:09:44 +0000	[thread overview]
Message-ID: <bb9b02af32d028fc0c26d372aa490e260c74e74d.1602079786.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.676.v4.git.1602079785.gitgitgadget@gmail.com>

From: Abhishek Kumar <abhishekkumar8222@gmail.com>

With corrected commit dates implemented, we no longer have to rely on
commit date as a heuristic in paint_down_to_common().

While using corrected commit dates Git walks nearly the same number of
commits as commit date, the process is slower as for each comparision we
have to access a commit-slab (for corrected committer date) instead of
accessing struct member (for committer date).

For example, the command `git merge-base v4.8 v4.9` on the linux
repository walks 167468 commits, taking 0.135s for committer date and
167496 commits, taking 0.157s for corrected committer date respectively.

t6404-recursive-merge setups a unique repository where all commits have
the same committer date without well-defined merge-base.

While running tests with GIT_TEST_COMMIT_GRAPH unset, we use committer
date as a heuristic in paint_down_to_common(). 6404.1 'combined merge
conflicts' merges commits in the order:
- Merge C with B to form a intermediate commit.
- Merge the intermediate commit with A.

With GIT_TEST_COMMIT_GRAPH=1, we write a commit-graph and subsequently
use the corrected committer date, which changes the order in which
commits are merged:
- Merge A with B to form a intermediate commit.
- Merge the intermediate commit with C.

While resulting repositories are equivalent, 6404.4 'virtual trees were
processed' fails with GIT_TEST_COMMIT_GRAPH=1 as we are selecting
different merge-bases and thus have different object ids for the
intermediate commits.

As this has already causes problems (as noted in 859fdc0 (commit-graph:
define GIT_TEST_COMMIT_GRAPH, 2018-08-29)), we disable commit graph
within t6404-recursive-merge.
