I'm wondering if it's just running too slowly and we're hitting race conditions in test cases.) thanks -- PMM --- /home/gitlab-runner/builds/-LCfcJ2T/0/qemu-project/qemu/tests/qemu-iotests/tests/copy-before-write.out +++ /home/gitlab-runner/builds/-LCfcJ2T/0/qemu-project/qemu/build/scratch/qcow2-file-copy-before-write/copy-before-write.out.bad @@ -1,5 +1,21 @@ -.... +...F +====================================================================== +FAIL: test_timeout_break_snapshot (__main__.TestCbwError) +---------------------------------------------------------------------- +Traceback (most recent call last): + File "/home/gitlab-runner/builds/-LCfcJ2T/0/qemu-project/qemu/tests/qemu-iotests/tests/copy-before-write", line 210, in test_timeout_break_snapshot + self.assertEqual(log, """\ +AssertionError: 'wrot[195 chars]read 1048576/1048576 bytes at offset 0\n1 MiB,[46 chars]c)\n' != 'wrot[195 chars]read failed: Permission denied\n' + wrote 524288/524288 bytes at offset 0 + 512 KiB, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec) + wrote 524288/524288 bytes at offset 524288 + 512 KiB, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec) ++ read failed: Permission denied +- read 1048576/1048576 bytes at offset 0 +- 1 MiB, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec) + + ---------------------------------------------------------------------- Ran 4 tests
