[jira] [Updated] (QPIDJMS-464) zero prefetch receive can hang if
timeout reached whilst message is partially transferred
[ https://issues.apache.org/jira/browse/QPIDJMS-464?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Robbie Gemmell updated QPIDJMS-464:
-----------------------------------
Description:
When a receive with timeout call is made and the client configured to use zero prefetch, the client issues a credit, waits for a message to arrive, and if one doesn't in the given time it drains the credit to either get a message or ensure there is none available and remove the credit. If the message is already partially transferred (i.e it is multi-framed and so likely a larger message) at this point the client knows it doesn't need to drain, but the way it handles this triggers a later mishandling of completing the receive request when the message arrives.
Some related comments can be found [here|https://issues.apache.org/jira/browse/QPIDJMS-458?focusedCommentId=16872498&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-16872498] onwards.
