When executing “make test -jX” (with X > 1) to build and run tests in a
build directory, there is a race condition between the
serial_test_low_level target and the test_prep target (a dependency of
serial_test_fishscript and serial_test_interactive).
As far as I can tell, these events happen in a serial build scenario
(“make test” with the “Unix Makefiles” CMake generator):
1. The fish_tests binary is built and executed.
2. The test_prep target (a dependency of serial_test_fishscript)
cleans up test directories.
3. Tests in test.fish are executed.
In a parallel build scenario, this often happens:
1. Build of the fish_tests binary is started.
2. The test_prep target cleans up test directories.
3. Build of the fish_tests binary is finished.
4. Execution of the fish_tests binary starts.
5. Execution of the fish_tests binary finishes.
6. Tests in test.fish are executed.
However, if building the fish_tests binary is fast enough but not
instant (e.g. when using ccache), this can happen:
1. Build of the fish_tests binary is started.
2. Build of the fish_tests binary is finished.
3. Execution of the fish_tests binary starts.
4. The test_prep target cleans up test directories.
5. fish_tests tests that depend on said test directories may,
depending on timing, fail because they are wiped by test_prep.
Fix this by making test_prep a dependency of serial_test_low_level so
that test_prep can’t interfere with fish_tests execution.
