Subject [jira] [Updated] (DERBY-5445) Enhance existing concurrency test to stress sequence generators to also stress identity columns
Date Mon, 17 Oct 2011 09:26:12 GMT

     [ https://issues.apache.org/jira/browse/DERBY-5445?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Knut Anders Hatlen updated DERBY-5445:
--------------------------------------

    Attachment: fix-init-msg.diff

The original "initializing database..." message was changed by this issue to "initializing
database for identity column testing..." or "initializing database for sequence generator
testing..."

Although the new messages are more accurate when testing identity columns or sequence generators,
they are wrong when running the other tests that don't use identity columns or sequence generators.

The attached patch changes the message back to the original.

Committed revision 1185056.

> DERBY-4565 added a concurrency test for sequence generators to test the possible race
condition for allocating a new range of pre-allocated numbers for the sequence. I have been
looking at enhancing that test to provide similar test for identity columns. I plan to add
another command line parameter to the test which will run the concurrency test to stress identity
column generator.
