This defines functions to let logging services add error log events to performance_schema.error_log.
For documentation of the individual functions, see log_sink_perfschema.cc Primitives for logging services to add to performance_schema.error_log.
| log_service_error(* s_mysql_log_sink_perfschema::event_add) (ulonglong timestamp, ulonglong thread_id, ulong prio, const char *error_code, uint error_code_length, const char *subsys, uint subsys_length, const char *message, uint message_length) |
Add a log-event to the ring buffer.
We require the various pieces of information to be passed individually rather than accepting a log_sink_pfs_event so we can sanity check each part individually and don't have to worry about different components using different versions/sizes of the struct.
We copy the data as needed, so caller may free their copy once this call returns.
