[jira] [Commented] (PROTON-2231) Assertion fail on macOS with libuv in c-threaderciser test

["Roddie Kieley (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/PROTON-2231?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17227457#comment-17227457 ] 

Roddie Kieley commented on PROTON-2231:
---------------------------------------

Investigation ongoing. Seeing two variations of the hang at the end of the threaderciser using the following on a 6 core i7 based mac:
{code}
for i in {1..10}; do `echo echo $i; date +%H:%M:%S; ./c-threaderciser -time 10 -threads 12`; done;
{code}
This hangs the very first time it runs in many cases in one of two places
{code}
for (i = 0; i < threads/2; ++i) pthread_join(proactor_threads[i], &ignore);
{code}
with 6 of the 7 threads sitting in pn_proactor_wait

OR threaderciser hangs at
{code}
global_destroy(&g)
{code}

which itself is hung on
{code}
pn_proactor_free(g->proactor);
{code}

As well I also see the Assertion failed from the above comment periodically. More investigation and understanding required to put the pieces together.

> As described on PROTON-2225, the test fails with assertion error. It is currently disabled on macOS for this reason (in .travis.yml).

> If the test is meant to stay disabled for a longer time, it will have to be disabled in CMakeLists.txt, so that users compiling the project do not run it accidentally.
