Thanks for the heads-up. It turns out that "in_merge_bases_many()"
returns different results depending on "GIT_TEST_COMMIT_GRAPH".
Initially I thought that it might be related to batching the entries,
but that is not the case.
One of the tests that is failing is:
cd src &&
git switch branch &&
test_commit I &&
git switch master &&
test_commit J &&
git pull --rebase origin master &&
git push --force-if-includes --force-with-lease="master"
Here, we are testing to check if forced updates are allowed after
the remote changes have been incorporated locally, which is true
in this case and should pass.
"in_merge_bases_many()" used in the check as follows:
for (chunk = list.items; chunk < list.items + list.nr; chunk += size) {
size = list.items + list.nr - chunk;
if (MERGE_BASES_BATCH_SIZE < size)
size = MERGE_BASES_BATCH_SIZE;
if ((ret = in_merge_bases_many(commit, size, chunk)))
break;
}
In "repo_in_merge_bases_many()" [1], the following condition evaluates
to true when "GIT_TEST_COMMIT_GRAPH" is 1.
generation = commit_graph_generation(commit);
if (generation > min_generation)
return ret;
Unfortunately, I am unfamiliar with the code, and not sure why this
happens; I remember Junio mention [2] something about generation
numbers could it be related to that?
A possible "workaround" is to use "in_merge_bases()" for each of the
commits we collect in the list, and the tests seem to pass with
"GIT_TEST_COMMIT_GRAPH" being set; but I wonder if that's the right
way to fix this.
