Alan Conway commented on QPID-154:
----------------------------------
When complete, update daemon quit/kill tests to verify from logs that daemon was shut down correctly.
> Logging/tracing for C++.

> Key: QPID-154
> URL: https://issues.apache.org/jira/browse/QPID-154
> Project: Qpid
> Issue Type: New Feature
> Components: C++ Broker, C++ Client
> Affects Versions: M2
> Reporter: Alan Conway

> Qpid needs logging infrastructure for user logging and debug tracing.
> Performance is critical, in particular the descision *not* to log a disabled messages must be extremely cheap so that disabled logging statements have no significant performance impact.
> Ideally a single system for both user logging and debug tracing so that debug tracing can be left in release builds and enabled to diagnose problems in the users's environment.
> Only if we can't get acceptable performance should we consider a separate debug tracing facility that is compiled out of release builds for tracing critical code.
> Highly desirable to use an existing open source solution rather than reinvent the wheel provided we can find one that is acceptable, need some research & discussion on dev list before selecting and implementing.
> Having the file/line in exception messages (as qpid does currently) is valuable, qpid::Exception should take a srcline parameter.
> Low-level tracing should provide function entry-exit logging via a macro+guard object that logs in constructor/destructor. (note BOOST_FUNCTION_NAME gives the current function name in a macro)
