[jira] [Created] (QPID-3231) timeout period used during synchronous
0-8/0-9 operations may begin before transmission of the operation occurs
timeout period used during synchronous 0-8/0-9 operations may begin before transmission of the operation occurs
---------------------------------------------------------------------------------------------------------------
Key: QPID-3231
URL: https://issues.apache.org/jira/browse/QPID-3231
Project: Qpid
Issue Type: Bug
Components: Java Client
Affects Versions: 0.8, 0.7, 0.6, 0.5, 0.9, 0.10
Reporter: Robbie Gemmell
Fix For: 0.11
The timeout period used during synchronous 0-8/0-9 operations may begin before transmission of the operation actually occurs.
If a large amount of data is sent (asynchronously) before a synchronous operation is performed (e.g session commit) then this data may still be in the effectively unbounded network buffers and delay transmission of the frames for the synchronous operation. However, the timer used to indicate timeout of the synchronous operation begins as soon as the asynchronous send operation for it returns, and so could also include time spent transmitting the previous data asynchronously. This would mean that the synchronous operation is timed out prematurely, and may later succeed once the command is actually placed on the wire.
We should ensure that the send method only returns once the data is actually on the wire when it used for synchronous operations with timeouts.

Andrew MacBean closed QPID-3231.
--------------------------------
Resolution: Not A Problem
Since the removal of MINA this is no longer an issue.
Raised new JIRA for removal of now unused system property: QPID-3511
