travis: analyze core files resulting from tests #28

Closed mdavidsaver closed 4 years ago

mdavidsaver commented 4 years ago

Add core-dumper.py which hooks into the Linux kernel core_pattern facility to redirect core files. The net result is a stack trace of all threads for any test which produces a core (SIGSEGV or abort()).

The only added requirement is to have gdb installed. If it isn't, then core-dumper.py is a no-op (as on OSX). The rest is self-contained within build.sh.

On second thought, this should be a separate module. I'm going to want core dump analysis in basically all of my CI builds.

Why does that push for a separate module?

mdavidsaver commented 4 years ago

Complexity mainly. This code is hooking into OS specific hooks which aren't often used. And I think it benefits from its own (much faster) set of CI tests. work in progress at https://github.com/mdavidsaver/ci-core-dumper
