Bug 178700 – [WPE] Cannot get backtrace from WPE release bot

• Component: WPE WebKit
• Status: RESOLVED FIXED

[Michael Catanzaro]

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.

This probably needs to be fixed in the same way that Fujii fixed https://trac.webkit.org/changeset/228731/webkit.

Also, I'm skeptical about the "DatabaseProcess" literal as that *should* have been renamed to StorageProcess. Not sure if that actually happened, though.
