[jira] [Resolved] (DISPATCH-1795) Avoid clutter in debug output by
not printing traceback of suppressed leaks
[ https://issues.apache.org/jira/browse/DISPATCH-1795?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Ken Giusti resolved DISPATCH-1795.

Resolution: Fixed

>
> 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
> Priority: Major
> Fix For: 1.15.0
>
>
> 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}

> Non-suppressed items would include the backtrace of course.
