It's always a pain to get a core dump when enabling user/group setting (which disables the dumpable flag on Linux), when using a chroot and/or when haproxy is started by a service management tool which requires complex operations to just raise the core dump limit. This patch introduces a new "set-dumpable" global directive to work around these troubles by doing the following : - remove file size limits (equivalent of ulimit -f unlimited) - remove core size limits (equivalent of ulimit -c unlimited) - mark the process dumpable again (equivalent of suid_dumpable=1) Some of these will depend on the operating system. This way it becomes much easier to retrieve a core file. Temporarily moving the chroot to a user-writable place generally enough.
