merge-ort handles submodules (and directory/file conflicts in general) differently than merge-recursive does; it basically puts all the special handling for different filetypes into one place in the codebase instead of needing special handling for different filetypes in many different code paths. This one code path in merge-ort could perhaps use some work still (there are still test_expect_failure cases in the testsuite), but it passes all the tests that merge-recursive does as well as 12 additional ones that merge-recursive fails. Mark those 12 tests as test_expect_success under merge-ort.

|
|
# ('child') hard-resets its branch to a new root commit with the same tree as the one
|
|
# from the upstream superproject, so that its branch has no merge-base with its
|
|
# remote-tracking counterpart, and then calls 'git pull --recurse-submodules --rebase'.
|
|
# The result is that the local branch is reset to the remote-tracking branch (as it was
|
|
# originally before the hard-reset).
|
|
|
|
# The only commit in the range generated by 'submodule.c::submodule_touches_in_range' and
|
|
# passed to 'submodule.c::collect_changed_submodules' is the new (regenerated) initial commit,
|
|
# which adds the submodule.
|
|
# However, 'submodule_touches_in_range' does not error (even though this commit adds the submodule)
|
|
# because 'combine-diff.c::diff_tree_combined' returns early, as the initial commit has no parents.
