From c849c48d19cc0b086f98688d760fa6e008adc50e Mon Sep 17 00:00:00 2001 From: Thiago Macieira Date: Tue, 11 Oct 2022 09:38:42 -0700 Subject: Autotest/Unix: request zero-sized core dumps for crashing code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Unix systems have got crash loggers in the past 15-20 years, notably macOS and Linux (abrtd, systemd-coredumpd, etc.). By setting the core dump limit to zero, those tools should be mostly inhibited from running and thus not interfere with the parent process' timeouts. Even for systems without core dump loggers, disabling the writing of a core dump to the filesystem should also help.
