test_readline fails randomly on aarc64 RHEL8 buildbots (3.9, 3.10 and 3.x). In some builds, test_readline fails but then pass when re-run in verbose mode.

I ran the test manually on the buildbot worker. Sometimes, the test process gets the EIO error even before getting the 2 newline bytes (b"\r\n"). I wrote PR 27813 to simply not expect the newline character. Adding flush=True to the print("History length:", readline.get_current_history_length()) call in the Python script doesn't fix the issue. |
