ISSUE: 6001
|
|
TITLE: Invalid parameters of gds transaction in ISQL
|
|
DESCRIPTION:
|
|
ISQL hangs when trying to show various system objects in a case when other attachment has uncommitted changes to that objects
|
|
We create (in Python connection) one table TEST1 with PK and commit transaction.
|
|
Then we create second (similar) table TEST2 but do not commit transaction.
|
|
After this we launch ISQL in async. mode and ask him to perform SHOW TABLE and SHOW INDEX commands.
|
|
ISQL:
|
|
1) should NOT hang (it did this because of launching Tx in read committed NO record_version);
|
|
2) should output only info about table TEST1 and ints PK index.
|
|
3) should not output any info about non-committed DDL of table TEST2.
|
|
|
|
Confirmed bug on 3.0.3.32837 and 4.0.0.800 (ISQL did hang when issued any of 'SHOW TABLE' / 'SHOW INDEX' copmmand).
