@ -41,6 +41,12 @@ NOTES:
Appearance of 'gfix' process is checked in loop by querying mon$attachments, see also: MAX_WAIT_FOR_SWEEP_START_MS.
More precise pattern for line with message about failed sweep (see 'p_sweep_failed').
Checked on Windows and Linux: 3.0.8.33535 (SS/CS), 4.0.1.2692 (SS/CS), 5.0.0.730
[22.02.2023] pzotov
During run on 5.0.0.958 SS, "Windows fatal exception: access violation" error occurs and its full text + stack was 'embedded'
in the pytest output. This error happens on garbage collection of Python code, when Statement destructor (__del__) was executed.
Although all resources, including prepared statement, are used here within 'with' context manager, it will be good to put every
'ps' usage inside 'with' block related to appropriate cursor. Before this, second 'ps' usage was linked to 1st [closed] cursor,
so this may be relate4d somehow to this AV.
