When running test_timestamp08.py with disagg hook, an assertion was raised getting an unexpected timestamp for the all_durable query before transaction commit:
====================================================================== [pid:6625]: FAIL: None ---------------------------------------------------------------------- [pid:6625]: Traceback (most recent call last): File "/home/ubuntu/work/wiredtiger/test/suite/wttest.py", line 243, in _callTestMethod method() File "/home/ubuntu/work/wiredtiger/test/suite/test_timestamp08.py", line 265, in test_all_durable self.assertTimestampsEqual(self.conn.query_timestamp('get=all_durable'), self.timestamp_str(9)) File "/home/ubuntu/work/wiredtiger/test/suite/wttest.py", line 734, in assertTimestampsEqual self.assertEqual(int(ts1, 16), int(ts2, 16)) AssertionError: 0 != 9
The command to reproduce the failure:
$ python3 ../test/suite/run.py -v 2 --hook disagg test_timestamp08.py
