             Summary: Improved logging API
                 Key: PROTON-2131
                 URL: https://issues.apache.org/jira/browse/PROTON-2131
             Project: Qpid Proton
          Issue Type: New Feature
          Components: proton-c
            Reporter: Andrew Stitcher
            Assignee: Andrew Stitcher


Problems with current proton logging:
 * There are multiple logging systems that are not connected

 - {{pn_log_*}} is used for some things that are not connected to an AMQP
 connection (but not all things)
 - pn_transport_t has its own logging system that is the major logging
 system in proton, with an {{pn_transport_logf()}} and friends API and an
 ability to sink the log its output log messages using
{{pn_transport_set_tracer()}}. However not everything that might need to
 log messages is connected to a {{pn_transport_t}} so it makes a lot more
 sense for logging to be its own system that the {{pn_transport_t}} is
 connected to rather than the other way around.

 * The logging only has a set of vague somewhat amorphous trace flags to
 decide which messages get logged. Currently the only coherent use for
 this subsystem is to set the environment variable {{PN_TRACE_FRM}} to get
 AMQP frame traces. There are other environment variable which produce
 output (and flags can be set programmatically by client programs) but
 which flags produce what output is not very systematic. There is no way
 to output only logging related to SSL/TLS for example.

 * The callback function that an application can attach to receive the
 log messages only gets the message and maybe the {{pn_transport_t}} that is
 associated, but no indication of the severity or what pert of the
 library it came from.
