ISSUE: Hang when database with disconnect trigger using MON$ tables is shutting down
|
|
TITLE:
|
|
DESCRIPTION:
|
|
NOTES:
|
|
[02.02.2024] pzotov
|
|
### ACHTUNG ###
|
|
Bug could NOT be reproduced on Windows.
|
|
Bug can be reproduced only when appropriate code runs OUTSIDE current firebird-QA framework, i.e. directly from OS.
|
|
Because of that, this test creates temporary .py script which is launched further using subprocess.run( [ sys.executable ...] )
|
|
Confirmed problem on 6.0.0.219: 'gfix -shut full -force 0' hangs.
|
|
Checked on 6.0.0.244.
