             Summary: Refactor logging so that it doesn't allocate any heap 
memory
                 Key: PROTON-2562
                 URL: https://issues.apache.org/jira/browse/PROTON-2562
             Project: Qpid Proton
          Issue Type: Improvement
          Components: proton-c
            Reporter: Andrew Stitcher
            Assignee: Andrew Stitcher


Currently the logging subsystem depends on the pn_string_t class to manage the 
messages that it sends out. This means that it is subject heap allocations at 
unknown time with unknown amounts.

Given that a logging subsystem should always succeed and take as little time as 
possible, it would be much better to avoid any allocations at all, but at 
eliminating as many as possible will be a significant improvement.
