Subject [jira] Updated: (DERBY-4982) Retrying after interrupts in store pops a bug in derbyall/storeall/storeunit/T_RawStoreFactory in some cases
Date Tue, 25 Jan 2011 04:52:43 GMT

     [ https://issues.apache.org/jira/browse/DERBY-4982?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Dag H. Wanvik updated DERBY-4982:
---------------------------------

    Attachment: derby-4982.stat
                derby-4982.diff

Uploading a patch which makes store throw a session level exception (after releasing the latch
and notifying an other threads) for both sane and insane, instead of assert for sane, and
in stead of waiting eternally fo insane,  In stead of 08000, I made a new error, DATA_DOUBLE_LATCH_INTERNAL_ERROR
for this situation.I chose not to make it database level since the the thread is only dead-locked
with itself and we have no sign that the database is compromised. Maybe it is overkill to
make a new error for this internal error which is not expected to happen, but according to
Knut, waiting for lock timeout is no longer an option: we get an eternal hang. Opinions are
welcome as always.

The test code has been adjusted accordingly.

Running regressions.
