Andy Jefferson commented on JDO-623:
------------------------------------
JDO TCK SVN will look for datanucleus-core/datanucleus-jpa 2.0.1-
SNAPSHOT. They are in the DN M2 nightly repo (and also the DN M1
nightly repo I'd guess). Just running Maven not "offline" should
find them.
Query cancel and timeout support
--------------------------------
Key: JDO-623
URL: https://issues.apache.org/jira/browse/JDO-623
Project: JDO
Issue Type: New Feature
Components: api2, tck2
Reporter: Andy Jefferson
Fix For: JDO 2 maintenance release 3
Attachments: JDO-623-mbo.patch, JDO-623-tck2-mbo.patch,
JDO-623-testcase.patch, jdo623.patch, pmf_option.patch,
query.patch, query_timeout.patch
JDO doesn't have a mechanism to stop queries from overrunning. JPA2
now allows
a persistence property to allow timing them out, and most JDO
implementations
have allowed this as an extension since JDO1. It would make sense
for JDO
(2.3) to have the same or a variation. I propose having the following
Simple PMF property "javax.jdo.option.queryTimeout" to specify the
number of millisecs (or secs) before any query is timed out. Throw
a QueryTimeoutException (extends JDOException) when the timeout
happens.
Add methods Query.setTimeout(int), Query.getTimeout() to allow
setting/retrieving the timeout interval on a per-query basis.
Add method Query.cancel() to cancel any running query. If an
implementation doesn't support cancelling of queries then it should
throw a JDOUnsupportedOptionException. Any query execute() that is
cancelled will throw a QueryInterruptedException (extends
JDOUserException).
