submodule tests: use symbolic-ref --short to discover branch name

2021-05-11T03:45:18Z

Change a use of $GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME added in 704fed9ea22 (tests: start moving to a different default main branch name, 2020-10-23) to simply discover the initial branch name of a repository set up in this function with "symbolic-ref --short". That's something done in another test in 704fed9ea22, so doing it like this seems like an omission, or rather an overly eager search/replacement instead of fixing the test logic. There are only three uses of the GIT_TEST_DEFAULT_INITIAL_BRANCH_NAME variable in the test suite, this gets rid of one of those. Signed-off-by: Ævar Arnfjörð Bjarmason Signed-off-by: Junio C Hamano

stash: remove unnecessary process forking

2020-12-01T22:39:04Z

When stash was converted from shell to a builtin, it merely transliterated the forking of various git commands from shell to a C program that would fork the same commands. Some of those were converted over to actual library calls, but much of the pipeline-of-commands design still remains. Fix some of this by replacing the portion corresponding to git diff-index --cached --name-only --diff-filter=A $CTREE >"$a" git read-tree --reset $CTREE git update-index --add --stdin <"$a" rm -f "$a" into a library function that does the same thing. (The read-tree --reset was already partially converted over to a library call, but as an independent piece.) Note here that this came after a merge operation was performed. The merge machinery always stages anything that cleanly merges, and the above code only runs if there are no conflicts. Its purpose is to make it so that when there are no conflicts, all the changes from the stash are unstaged. However, that causes brand new files from the stash to become untracked, so the code above first saves those files off and then re-adds them afterwards. We replace the whole series of commands with a simple function that will unstage files that are not newly added. This doesn't fix any bugs in the usage of these commands, it simply matches the existing behavior but makes it into a single atomic operation that we can then operate on as a whole. A subsequent commit will take advantage of this to fix issues with these commands in sparse-checkouts. This conversion incidentally fixes t3906.1, because the separate update-index process would die with the following error messages: error: uninitialized_sub: is a directory - add files inside instead fatal: Unable to process path uninitialized_sub The unstaging of the directory as a submodule meant it was no longer tracked, and thus as an uninitialized directory it could not be added back using `git update-index --add`, thus resulting in this error and early abort. Most of the submodule tests in 3906 continue to fail after this change, this change was just enough to push the first of those tests to success.

tests: start moving to a different default main branch name

2020-10-23T15:57:40Z

To allow for an incremental conversion to a new default main branch name, let's introduce `GIT_TEST_DEFAULT_MAIN_BRANCH_NAME`. This environment variable can be set at the top of each converted test script, overriding the default main branch name to use when initializing new repositories (or cloning empty repositories). Note: the `GIT_TEST_DEFAULT_MAIN_BRANCH_NAME` is _not_ intended to be used manually; many tests require a specific main branch name and cannot simply work with another one. This `GIT_TEST_*` variable is meant purely for the transitional period while the entire test suite is converted to use `main` as the initial branch name by default. We also introduce the `PREPARE_FOR_MAIN_BRANCH` prereq that determines whether the default main branch name is `main`, and adjust a couple of test functions to use it. This prereq will be used to temporarily disable a couple test cases to allow for adjusting the test script incrementally. Once an entire test is adjusted, we will adjust the test so that it is run with `GIT_TEST_DEFAULT_MAIN_BRANCH_NAME=main`. Signed-off-by: Johannes Schindelin Signed-off-by: Junio C Hamano

t: remove test_oid_init in tests

2020-07-30T16:16:49Z

Now that we call test_oid_init in the setup for all test scripts, there's no point in calling it individually. Remove all of the places where we've done so to help keep tests tidy. Signed-off-by: brian m. carlson Reviewed-by: Eric Sunshine Signed-off-by: Junio C Hamano

lib-submodule-update: pass 'test_must_fail' as an argument

2020-06-24T15:54:18Z

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 Signed-off-by: Junio C Hamano

lib-submodule-update: prepend "git" to $command

2020-06-12T18:33:40Z

Since all invocations of test_submodule_forced_switch() are git commands, automatically prepend "git" before invoking test_submodule_switch_common(). Similarly, many invocations of test_submodule_switch() are also git commands so automatically prepend "git" before invoking test_submodule_switch_common() as well. Finally, for invocations of test_submodule_switch() that invoke a custom function, rename the old function to test_submodule_switch_func(). This is necessary because in a future commit, we will be adding some logic that needs to distinguish between an invocation of a plain git comamnd and an invocation of a test helper function.

lib-submodule-update: consolidate --recurse-submodules

2020-04-29T17:36:55Z

Both test_submodule_switch_recursing_with_args() and test_submodule_forced_switch_recursing_with_args() call the internal function test_submodule_recursing_with_args_common() with the final argument of `--recurse-submodules`. Consolidate this duplication by appending the argument in test_submodule_recursing_with_args_common(). Signed-off-by: Denton Liu Signed-off-by: Junio C Hamano
