Hi Alexis,
I made a patch to remove the deadlock in the histogram [1]. But
since the trace has a faulty timestamp, I cannot guarantee the
application behaves entirely correctly. I don't have any analyses
other than statistics and histogram, which work fine now. So if
you spot anything else that seems problematic with such a trace,
let us know!

Best regards,
Geneviève

Hi Genevieve,
I updated our
application to the last version of Trace Compass (5.3), and
the issue is still there, but from now on I would be able to
test patches.
Thank you,
Alexis
Hi Alexis,
So babeltrace detects it as a malformed trace? What is the
exact output of babeltrace? Maybe it's simply something that
we did not implement in Trace Compass yet.
Would you be allowed to share the trace with us?

To
avoid analyzing events that are malformed, I would like to
verify in the trace if there is any inconsistencies. But
I’m struggling to find how to do that outside of trace
compass source code, before any analysis are performed to
avoid ending in a deadlock.
Do
you know what I could use to do that ?
For now, you can first read the trace with babeltrace to make
sure it is ok. But Trace Compass should be able to figure out.
I'll try to fix the dealock you mention at least, thanks for
providing the stack trace, I'll see what can easily be done.
Can you test patches (ie running from Trace Compass sources)
or do use one of the Trace Compass RCP? If so, which version
of Trace Compass are you using? In any case, have you tried
the latest version (5.3) to make sure the bug is still
present?
Best regards,
Geneviève
