[PATCH] Produce a core dump file on error in mythfront/backend

[Lawrence Rust <lvr@…>]

Enabling a coredump after a SEGV or similar fault enables a post mortem backtrace to be obtained with gdb, which can be useful in debugging rare problems. See 'man 5 core' for coredump naming etc. See 'man gdb' and search for core

It's bad form to enable core dumps within an application. It's easy enough to enable this with ulimit in the startup script, and there you can also set the core pattern so all cores go to a single location that isn't likely to fill up and have knock on effects like crashing your mysql tables.

ulimit -c unlimited
echo 1 > /proc/sys/kernel/core_uses_pid
echo "/cores/core.%t.%u.%p.%e" > /proc/sys/kernel/core_pattern
