qpid-route hangs when connecting to the Java Broker ---------------------------------------------------
Key: QPID-2319 URL: https://issues.apache.org/jira/browse/QPID-2319 Project: Qpid Issue Type: Bug Components: python tools Reporter: Rob Godfrey When working on the QMF implementation in the Java Broker I found that the Python tools which use the qmf.console python API hung in the _waitForStable function of the Broker class Investigating showed that although the count of outstandingRequests did drop to zero (the condition the function is waiting for) it was not being alerted to this fact. Adding debugging information into the code I could see that on entering _waitForStable the count of outstanding requests was 1... After entering the wait() the count droppped to zero through a call to _decOustanding ... then increased again all the way up to through calls to incOutstanding 26... then again dropped all the way to 0. Looking at the code for _decOutstanding it's clear that the wait should be notified that the count has dropped to zero, as long as the syncInFlight variable is true. If this check is commented out (i.e. decOustanding calls notify even if syncInFlight is false) then the tools do not hang the conclusion would seem to be that something is setting syncInFlight to false causing the _waitForStable function to not receive notifications that it can stop waiting... -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online. --------------------------------------------------------------------- Apache Qpid - AMQP Messaging Implementation Project: http://qpid.apache.org Use/Interact: mailto:dev-subscr...@qpid.apache.org
