ij should remove async statements from session after completion
---------------------------------------------------------------
Key: DERBY-4560
URL: https://issues.apache.org/jira/browse/DERBY-4560
Project: Derby
Issue Type: Bug
Components: Tools
Affects Versions: 10.6.0.0
Reporter: Sylvain Leroux
ij has statements to execute (ASYNC) and join (WAIT FOR) asynchronous
statements.
Asynchronous statements are stored in the corresponding Session object. but -
as far as I can see - are never removed. This leads to memory leaks:
ij> CONNECT 'jdbc:derby:memory:dummy;create=true';
ij> WAIT FOR stmt;
IJ ERROR: No async statement exists with the name STMT
ij> ASYNC stmt 'VALUES(1),(2),(3)';
ij> WAIT FOR stmt;
1

3 rows selected
ij> WAIT FOR stmt;
ERROR XJ012: 'Statement' already closed.
After completion, WAIT FOR should remove the async statement from the session
since it is no longer useful.
