* test-pselect, test-select: use different portsPaul Eggert2023-03-224-5/+19
| | | | | | | | | | | | | I have observed rare and hard-to-reproduce problems with the GNU grep release candidate with ‘make -j5 check’ on Fedora 37 x86-64. One possibility is that test-pselect and test-select interfere with each other somehow when run simultaneously, as they use the same port. Work around this possibility by using different ports from each other, and from test-poll (which also uses 12345). Of course it’d be better if all these tests used system-assigned ports, but I assume that’d take more work. * tests/test-pselect.c, tests/test-select.c (TEST_PORT): New macro. * tests/test-select.h (TEST_PORT): Remove.
