Subject [jira] Closed: (UIMA-1477) UIMA AS client hangs while handling CPC request
Date Wed, 05 Aug 2009 13:22:14 GMT

     [ https://issues.apache.org/jira/browse/UIMA-1477?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jerry Cwiklik closed UIMA-1477.

    Resolution: Fixed

Fixed UIMA AS client to allow it to send a CPC request to a service even though it has not
sent any CASes. 

> UIMA AS client hangs while handling CPC request 
> ------------------------------------------------
>                 Key: UIMA-1477
>                 URL: https://issues.apache.org/jira/browse/UIMA-1477
>             Project: UIMA
>          Issue Type: Bug
>          Components: Async Scaleout
>            Reporter: Jerry Cwiklik
>            Assignee: Jerry Cwiklik
> When UIMA AS client is initialized it acquires a CPC semaphore to control when to send
a CPC request. The semaphore is released when a number of CASes sent equals a number of CASes
received. Only when equal the semaphore is released and the CPC request is allowed to be sent.

> In a case when a client is initialized but never sends any CASes this logic fails. The
semaphore is never released causing a hang while trying to acquire a semaphore in collectionProcessComplete().
> Add a new test case to replicate the problem.
> Fix the code to handle sending CPC from a client that doesnt send CASes to a service.
