Todd Lipcon updated KUDU-2384:
------------------------------
Status: In Review (was: Open)
> Disable periodic stack trace dumps when running under gdb
> ---------------------------------------------------------
>
> Key: KUDU-2384
> URL: https://issues.apache.org/jira/browse/KUDU-2384
> Project: Kudu
> Issue Type: Bug
> Components: test
> Affects Versions: 1.7.0
> Reporter: Adar Dembo
> Assignee: Todd Lipcon
> Priority: Major
>
> The new periodic stack trace dump functionality involves sending SIGUSR2
> signals between threads from time to time. If you are running a Kudu server
> or test under gdb, this has the annoying habit of stopping gdb momentarily
> until you disable it via {{handle SIGUSR2 nostop noprint}}.
> Perhaps we should disable this functionality altogether if we're running
> inside gdb. [This SO
> post|https://stackoverflow.com/questions/3596781/how-to-detect-if-the-current-process-is-being-run-by-gdb]
> has some ideas. I also wonder whether we should check for gdb just once at
> startup or before every dump; the latter would obviate the workaround when
> attaching to a live server.
