Tom Lane 25dd07e0f6 Fix uuid-ossp regression tests based on buildfarm feedback. The previous version of these tests expected uuid_generate_v1() to always emit MAC addresses with the local-admin and multicast address bits zero. However, several of the buildfarm critters are reporting values with the local-admin bit set. (Perhaps they're running inside VMs or jails.) And a couple are reporting values with the multicast bit set, probably meaning that the UUID library couldn't read the system MAC address. Also, it emerges that if OSSP UUID can't read the system MAC address, it falls back to V1MC behavior wherein the whole node field gets randomized each time, breaking the test that expected the node field to remain stable in V1 output. (It looks like e2fs doesn't behave that way, though.) It's not entirely clear why we can't get a system MAC address, since the buildfarm scripts would not work without internet access. Nonetheless, the regression tests had better cope with the case, so adjust the tests to expect these behaviors.	11 years ago
