* | | MDEV-15051: signal handler - output information about the core generationDaniel Black2019-05-011-4/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The working directory, resource limits and core pattern will aid the user finding a core file in the case of failure. While the core file size is most relevant however other resource limits may give a clue as the the cause of the fatal signal so include them also. As signal handler functions are limited, proc filesystem reads/ readlink calls are used instead of the more obvious getcwd/getrlimits functions which aren't listed as signal safe. Results in output of the form: Writing a core file: working directory at /tmp/datadir Resource Limits: Limit Soft Limit Hard Limit Units Max cpu time unlimited unlimited seconds Max file size unlimited unlimited bytes Max data size unlimited unlimited bytes Max stack size 8388608 unlimited bytes Max core file size unlimited unlimited bytes Max resident set unlimited unlimited bytes Max processes 47194 47194 processes Max open files 1024 4096 files Max locked memory 65536 65536 bytes Max address space unlimited unlimited bytes Max file locks unlimited unlimited locks Max pending signals 47194 47194 signals Max msgqueue size 819200 819200 bytes Max nice priority 0 0 Max realtime priority 0 0 Max realtime timeout unlimited unlimited us Core pattern: |/usr/libexec/abrt-hook-ccpp %s %c %p %u %g %t %P %I Segmentation fault (core dumped) Closes #537

| | * | [MDEV-9127] Crash reporter often fails to show the query that crashedVicențiu Ciorbaru2016-07-121-1/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Addreses are not necessarily between heap_start && heap_end. Malloc calls using mmap can place pointers outside these bounds. In this case, we'll warn the user that the query pointer is potentially invalid. However, we'll attempt to print the data anyway after we're done printing everything else.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - If run with valgrind, mysqltest will now wait longer when syncronizing slave with master - Ensure that we wait with cleanup() until slave thread has stopped. - Added signal_thd_deleted() to signal close_connections() that all THD's has been freed. - Check in handle_fatal_signal() that we don't use variables that has been freed. - Increased some timeouts when run with --valgrind Other things: - Fixed wrong test in one_thread_per_connection_end() if galera is used. - Removed not needed calls to THD_CHECK_SENTRY() when we are calling 'delete thd'.
