Bug 234272 – GTK EWS crashlogs contain no useful information.

• Status: NEW
• Component: Tools / Tests

[Jean-Yves Avenard [:jya]]

Similar to bug 233614 (windows crash log are empty). This is for GTK

Example:
https://ews-build.webkit.org/#/builders/35/builds/2902
When attempting to view the crash log:
https://ews-build.s3-us-west-2.amazonaws.com/GTK-WK2-Tests-EWS/r446967-2902/results.html

You get useless output:

GTK post-commit Buildbot shows backtraces as expected.

GTK-Linux-64-bit-Release-Tests
https://build.webkit.org/#/builders/57/builds/5154

This seems GTK EWS bots configuration.

[Carlos Alberto Lopez Perez]

There are two issue here:

1. WTFCrash() on GTK doesn't anymore report the symbol names due to https://bugs.webkit.org/show_bug.cgi?id=181916#c96

2. The crashlogs (gdb backtraces) still work but on the workers for the EWS are 
not enabled. This is a local configuration issue. I will fix it.

Thanks for the notice.

I think this should be fixed. The GTK WK2 EWS should be reporting crash logs now. Let me know if it doesn't
