QMF Main-Loop Integration
-------------------------
Key: QPID-3484
URL: https://issues.apache.org/jira/browse/QPID-3484
Project: Qpid
Issue Type: Improvement
Components: Qpid Managment Framework
Reporter: Ted Ross
Assignee: Ted Ross
Priority: Minor
Fix For: 0.13
This improvement to the qmf interface in cpp/include/qmf provides an optional
event notifier that can be integrated into the application's main loop allowing
the application to block on multiple event sources including QMF sessions.
The solution provides platform-specific classes for use in different platforms.
The commit associated with this Jira supports only Posix FDs for integration
with main-loops based on select or poll. A future enhancement will provide a
Windows notifier based on a HANDLE.
Prior to this enhancement, applications that block on multiple event sources
(i.e. sockets, files, etc.) had two choices for working with qmf sessions:
Poll periodically for events, thus introducing high latency in the overall
operation; or spin rapidly on the qmf session thus creating high CPU loads.
