So the plan is to turn on the commit graph for the whole test suite excluding these selected tests? > diff --git a/t/t0410-partial-clone.sh b/t/t0410-partial-clone.sh > index 4984ca583d..73d5284a91 100755 > --- a/t/t0410-partial-clone.sh > +++ b/t/t0410-partial-clone.sh > @@ -181,7 +181,7 @@ test_expect_success 'rev-list stops traversal at missing and promised commit' ' > > git -C repo config core.repositoryformatversion 1 && > git -C repo config extensions.partialclone "arbitrary string" && > - git -C repo rev-list --exclude-promisor-objects --objects bar >out && > + GIT_TEST_COMMIT_GRAPH=0 git -C repo rev-list --exclude-promisor-objects --objects bar >out && > + GIT_TEST_COMMIT_GRAPH=0 && > + test_must_fail git merge -m final G This could go on the same line without the && in between, setting the variable as a prefix.
