[jira] Commented: (WAGON-220) Wagon HTTP Deadlocks under high load

John Casey commented on WAGON-220:
----------------------------------
Is this still an issue? I've added cleanupGetTransfer to the catch blocks of getInputStream(..) on the StreamWagon, to avoid problems there, but I'm not sure about releasing the connection from the get method just before we actually start reading from the InputStream resulting from that GET...not sure what the implications are for the connection maintenance, etc.

--------------------------------------
Attachment: WAGON-220.patch
Initial patch. This releases the connection for the GetMethod back into the pool.
We should have some tests for the connection releasing.

[jira] Closed: (WAGON-220) Wagon HTTP Deadlocks under high load
Posted by "John Casey (JIRA)" <ji...@codehaus.org>.
[ http://jira.codehaus.org/browse/WAGON-220?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
John Casey closed WAGON-220.
----------------------------
Assignee: John Casey
Resolution: Fixed
Fix Version/s: (was: 1.0)
1.0-beta-6
I've added code to ensure the current get method instance releases its connection when an error occurs, but I'm not sure of the wisdom of releasing the connection before reading from the method's response body...I simply don't know the internals of httpclient that well.
I'm closing this based on the code I added...if it's still an issue, reopen it and we should start from a failing test case.
