ISSUE: 4525
|
|
TITLE: An uncommitted select of the pseudo table sec$users blocks new database connections
|
|
DESCRIPTION:
|
|
JIRA: CORE-4200
|
|
FBTEST: bugs.core_4200
|
|
NOTES:
|
|
[08.12.2023] pzotov
|
|
Removed excessive split: code for FB 3.x and 4.x is identical.
|
|
Initial version of test (.in FBT framework) was created 29 may 2015, so one may to assume
|
|
that bug was fixed at that time. Current QA uses firebird-driver which has no ability to
|
|
make connection to such ancient FB version (3.0 Alpha1 ?). This means that we can not check
|
|
whether this test can reproduce source problem.
