62 | # Detect the exit code produced when our particular flavor of unzip | |
63 | # sees an empty archive. Infozip will generate a warning and exit with | |
64 | # code 1. But in the name of sanity, we do not expect other unzip | |
65 | # implementations to do the same thing (it would be perfectly | |
66 | # reasonable to exit 0, for example). | |
67 | # | |
68 | # This makes our test less rigorous on some platforms (unzip may not | |
69 | # handle the empty repo at all, making our later check of its exit code | |
70 | # a no-op). But we cannot do anything reasonable except skip the test | |
71 | # on such platforms anyway, and this is the moral equivalent. | |
