The shell functions in this patch enable crashing processes with the core limit set correctly to dump core in directory /cores. They do so by remounting the root partition, which is RAM-backed, and by creating the 0777-chmodded /cores under it. They also set the core file pattern in /proc/sys/kernel/core_pattern to be /cores/core.%p, such that a core dump will have the crashing process' PID appended to it. You enable core-dump generation once per boot, as follows: coredump-setup If a process does not have its core-size rlimit set (as most do not), you can either set it manually by typing "adb shell prlimit <pid> 4 -1 -1", or by typing coredump-enable <name>, e.g. coredump-enable $(pid mediaserver) Alternatively, you can cause a running process to dump core by sending it a SIGSEGV via the shell function core <name>, e.g.: core $(pid mediaserver) Change-Id: Ib174e7ee95515fb9866fa6bf0d5b5bf23f3ec61b Signed-off-by: Iliyan Malchev <malchev@google.com> |
