lib-submodule-update: pass 'test_must_fail' as an argument When we run a test helper function in test_submodule_switch_common(), we sometimes specify a whole helper function as the $command. When we do this, in some test cases, we just mark the whole function with `test_must_fail`. However, it's possible that the helper function might fail earlier or later than expected due to an introduced bug. If this happens, then the test case will still report as passing but it should really be marked as failing since it didn't actually display the intended behaviour. Instead of invoking `test_must_fail $command`, pass the string "test_must_fail" as the second argument in case where the git command is expected to fail. When $command is a helper function, the parent function calling test_submodule_switch_common() is test_submodule_switch_func(). For all test_submodule_switch_func() invocations, increase the granularity of the argument test helper function by prefixing the git invocation which is meant to fail with the second argument like this: $2 git checkout "$1" In the other cases, test_submodule_switch() and test_submodule_forced_switch(), instead of passing in the git command directly, wrap it using the git_test_func() and pass the git arguments using the global variable $gitcmd. Unfortunately, since closures aren't a thing in shell scripts, the global variable is necessary. Another unfortunate result is that the "git_test_func" will used as the test case name when $command is printed but it's worth it for the cleaner code. Finally, as an added bonus, `test_must_fail` will now only run on git commands. Signed-off-by: Denton Liu <liu.denton@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

wt-status: actually ignore submodules when requested Since ff6f1f564 (submodule-config: lazy-load a repository's .gitmodules file, 2017-08-03) rebase interactive fails if there are any submodules with unstaged changes which have been configured with a value for 'submodule.<name>.ignore' in the repository's config. This is due to how configured values of 'submodule.<name>.ignore' are handled in addition to a change in how the submodule config is loaded. When the diff machinery hits a submodule (gitlink as well as a corresponding entry in the submodule subsystem) it will read the value of 'submodule.<name>.ignore' stored in the repository's config and if the config is present it will clear the 'IGNORE_SUBMODULES' (which is the flag explicitly requested by rebase interactive), 'IGNORE_UNTRACKED_IN_SUBMODULES', and 'IGNORE_DIRTY_SUBMODULES' diff flags and then set one of them based on the configured value. Historically this wasn't a problem because the submodule subsystem wasn't initialized because the .gitmodules file wasn't explicitly loaded by the rebase interactive command. So when the diff machinery hit a submodule it would skip over reading any configured values of 'submodule.<name>.ignore'. In order to preserve the behavior of submodules being ignored by rebase interactive, also set the 'OVERRIDE_SUBMODULE_CONFIG' diff flag when submodules are requested to be ignored when checking for unstaged changes.
