65 | # Detect the exit code produced when our particular flavor of unzip | |

67 | # code 1. But in the name of sanity, we do not expect other unzip | |
68 | # implementations to do the same thing (it would be perfectly | |
69 | # reasonable to exit 0, for example). | |
70 | # | |
71 | # This makes our test less rigorous on some platforms (unzip may not | |
72 | # handle the empty repo at all, making our later check of its exit code | |
73 | # a no-op). But we cannot do anything reasonable except skip the test | |
74 | # on such platforms anyway, and this is the moral equivalent. | |
