getlogin: don’t assume one name per uid Problem reported by Wolfgang F. Muthmann (Bug#27640). * modules/getlogin-tests (Files): Add tests/test-getlogin_r.c. (ttyname): Remove test. * modules/getlogin_r-tests (ttyname): Remove test. * tests/test-getlogin.c: Replace this near-clone of test-getlogin_r.c with ‘#define TEST_LOGIN’ followed by ‘#include "test-getlogin_r.c"’. * tests/test-getlogin_r.c: If TEST_GETLOGIN is defined, test getlogin rather than getlogin_r. This avoids code duplication. (main): Use isatty and fstat rather than ttyname and stat. Use getpwnam instead of getpwuid, to be portable to test platforms that have multiple login names for the same uid.
