Subject [jira] [Updated] (DERBY-5233) Interrupt of create table or index (i.e. a container) will throw XSDF1 under NIO - connection survives
Date Mon, 30 May 2011 23:33:47 GMT

     [ https://issues.apache.org/jira/browse/DERBY-5233?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dag H. Wanvik updated DERBY-5233:
---------------------------------

    Attachment: DERBY-5233-1.stat
                DERBY-5233-1.diff

Uploading a patch for this problem. I also adds a new test case to InterruptResilienceTest:
testCreateDropInterrupted.

The patch makes RAFContainer, when seeing an interrupt exception during container creation,
close it down and try again, up to MAX_INTERRUPT_RETRIES times. Since RAFContainer should
work also under CDC/Foundation 1.1, the exceptions are checked using reflection (NIO classes
are excluded there).

Running regressions.

Note that this is less serious than in the cases referred to in DERBY-4741: here the database
does not get shut down, even the connection survives, cf the repro. So, this can be considered
a follow-up to DERBY-4741 to further improve Derby's robustness under interrupts.
