Dawid Weiss commented on LUCENE-3429: ------------------------------------- Not really. Thread.stop is deprecated and I know the reasons it is deprecated, but this doesn't mean it doesn't work. interrupt() is not a solution if you have busy code loops that never do any I/O or waiting/sleeping -- try interrupting while(true); and you'll see what I mean. The code I posted is correct. Thread.stop() is not even called because no methods do timeout at the moment. The problem with hangs and jre crashes is something else, but I didn't have the time to peek at it yet. > improve build system when tests hang > ------------------------------------ > > Key: LUCENE-3429 > URL: https://issues.apache.org/jira/browse/LUCENE-3429 > Project: Lucene - Java > Issue Type: Test > Reporter: Robert Muir > Fix For: 3.5, 4.0 > > Attachments: LUCENE-3429.patch, LUCENE-3429.patch > > > Currently, if tests hang in hudson it can go hung for days until we manually > kill it. > The problem is that when a hang happens its probably serious, what we want to > do (I think), is: > # time out the build. > # ensure we have enough debugging information to hopefully fix any hang. > So I think the ideal solution would be: > # add a sysprop "-D" that LuceneTestCase respects, it could default to no > timeout at all (some value like zero). > # when a timeout is set, LuceneTestCase spawns an additional timer thread for > the test class? method? > # if the timeout is exceeded, LuceneTestCase dumps all thread/stack > information, random seed information to hopefully reproduce the hang, and > fails the test. > # nightly builds would pass some reasonable -D for each test. > separately, I think we should have an "ant-level" timeout for the whole > build, in case it goes completely crazy (e.g. jvm completely hangs or > something else), just as an additional safety. -- This message is automatically generated by JIRA.
