Ken Giusti created DISPATCH-1795:
------------------------------------
Summary: Avoid clutter in debug output by not printing traceback
of suppressed leaks
Key: DISPATCH-1795
URL: https://issues.apache.org/jira/browse/DISPATCH-1795
Project: Qpid Dispatch
Issue Type: Improvement
Components: Routing Engine
Affects Versions: 1.14.0
Reporter: Ken Giusti
Fix For: Backlog
When a router that has been built for Debug exits the pool allocator will dump
stack tracebacks for all leaked pool objects.
This results in a lot of extra information appearing in the output.
To lessen the noise somewhat I propose avoiding printing the traceback for
those alloc pooled items that are suppressed. Keep printing the leak of the
suppressed item, just avoid the extra stack dump. For example:
{quote}alloc.c: Items of type 'qd_buffer_t' remain allocated at shutdown: 16
Leak: 2020-10-08 10:33:29.819821 -0400 type: qd_buffer_t address: 0x239ea10
(suppressed)

{quote}
Would now just print:
{quote}alloc.c: Items of type 'qd_buffer_t' remain allocated at shutdown: 16
Leak: 2020-10-08 10:33:29.819821 -0400 type: qd_buffer_t address: 0x239ea10
(suppressed)
{quote}
Non-suppressed items would include the backtrace of course.
