Subject [jira] [Updated] (DERBY-5185) store/rollForwardRecovery.sql stuck in RAFContainer4.recoverContainerAfterInterrupt() during shutdown
Date Mon, 18 Apr 2011 14:53:05 GMT

     [ https://issues.apache.org/jira/browse/DERBY-5185?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Dag H. Wanvik updated DERBY-5185:

    Attachment: derby-5185-3a.diff

Since we don't have a lot of time to gain confidence in the code right now with the impending
release, I'd like to avoid the possibility of further hangs in the interrupt handling by committing
a follow-up patch which adds max waiting time logic to the two remaining loops in the code
for threads waiting for a condition to become true: the "gain entry" logic in readPage and
writePage. It should not be necessary now that we have fixed the state maintenance code, but
just to be safe.. In normal operation it does not add overhead (just one extra counter comparison)
so it seems a cheap price to pay to avoid the prospect of a hang during shutdown - (which
constitute regression). If we max out we will throw FILE_IO_INTERRUPTED as elsewhere. Uploading
derby-5185-3a for this.
