Erick Erickson updated SOLR-7836: --------------------------------- Attachment: deadlock_test deadlock_3.res.zip Here's the stack trace. A few things: > I got this source by "svn checkout -r1694809 > https://svn.apache.org/repos/asf/lucene/dev/trunk" and added the test to that > code base. > It appears to need two things to fail; a reload operation and a delete by > query. > thread WRITER5 and > TEST-TestReloadDeadlock.testReloadDeadlock-seed#[4CFFCB253DB33784]" are the > ones I think are fighting here. > The original fix was to pass the index writer from addDoc0() to addAndDelete, > but this doesn't work either. I'll see if I can attach a run with that change > for comparison. > I've also attached the script I use to run this, although I don't run it in > parallel. > Possible deadlock when closing refcounted index writers. > -------------------------------------------------------- > > Key: SOLR-7836 > URL: https://issues.apache.org/jira/browse/SOLR-7836 > Project: Solr > Issue Type: Bug > Reporter: Erick Erickson > Assignee: Erick Erickson > Fix For: Trunk, 5.4 > > Attachments: SOLR-7836-synch.patch, SOLR-7836.patch, SOLR-7836.patch, > SOLR-7836.patch, deadlock_3.res.zip, deadlock_test > > > Preliminary patch for what looks like a possible race condition between > writerFree and pauseWriter in DefaultSorlCoreState. > Looking for comments and/or why I'm completely missing the boat. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
