ISSUE: 2170
|
|
TITLE: Expression index can be created while doing inserts into table
|
|
DESCRIPTION:
|
|
JIRA: CORE-1746
|
|
FBTEST: bugs.core_1746
|
|
NOTES:
|
|
[15.01.2022] pcisar
|
|
This test may FAIL when run on slow machine (like VM), or fast one (Windows 10 with SSD)
|
|
[19.09.2022] pzotov
|
|
Fully reimplemented. Issue described in the ticket can be easy reproduced WITHOUT any concurrent workload.
|
|
We can create table with single column and two connections. First of them just inserts one record and
|
|
second attempts to create index.
|
|
On 2.5.3.26780 and 3.0.0.32483 statement 'create index' will pass (and this must be considered as problem).
|
|
On 2.5.27020 and 3.0.1 such attempt leads to exception "-901 / object ... in use" - and this is expected.
|
|
See also core_4386_test.py.
|
|
|
|
Checked on 3.0.8.33535 (SS/CS), 4.0.1.2692 (SS/CS), 5.0.0.730 (SS/CS)
