            Bug ID: 178700
           Summary: [WPE] Cannot get backtrace from WPE release bot
           Product: WebKit
           Version: Other
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: WebKit WPE
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: mcatanzaro at igalia.com
                CC: bugs-noreply at webkitgtk.org, clopez at igalia.com

We have crashing tests on the WPE release bot, but no way to get backtraces out of them:

crash log for WPEWebProcess (pid 29100):

Coredump core-pid_29100.dump not found. To enable crash logs:

- run this command as super-user: echo "/var/www/cores/bb-wpe-release-test-64/core-pid_%p.dump" > /proc/sys/kernel/core_pattern
- enable core dumps: ulimit -c unlimited
- set the WEBKIT_CORE_DUMPS_DIRECTORY environment variable: export WEBKIT_CORE_DUMPS_DIRECTORY=/var/www/cores/bb-wpe-release-test-64


STDERR: <empty>

I also notice that we don't have WPE debug bots, so the backtrace is not going to be very useful even if it were present. If we're only going to have one bot, it's much more important to have a working debug bot IMO.
