Sergey Vojtovich	b8aceb707f	BUG#54989 - With null_audit installed, server hangs on an attempt to install a plugin twice Server crashes when [UN]INSTALL PLUGIN fails (returns an error) and general log is disabled and there are audit plugins interested in MYSQL_AUDIT_GENERAL_CLASS. When audit event is triggered, audit subsystem acquires interested plugins by walking through plugin list. Evidently plugin list iterator protects plugin list by acquiring LOCK_plugin, see plugin_foreach_with_mask(). On the other hand [UN]INSTALL PLUGIN is acquiring LOCK_plugin rather for a long time. When audit event is triggered during [UN]INSTALL PLUGIN, plugin list iterator acquires the same lock (within the same thread) second time. Repeatable only with general_log disabled, because general_log triggers MYSQL_AUDIT_GENERAL_LOG event, which acquires audit plugins before [UN]INSTALL PLUGIN acquired LOCK_plugin. With this fix we pre-acquire audit plugins for events that may potentially occur during [UN]INSTALL PLUGIN. This hack should be removed when LOCK_plugin is fixed so it protects only what it supposed to protect. No test case for this fix - we do not have facility to test audit plugins yet.	16 years ago
Sergey Vojtovich	1b12f4c233	BUG#47059 - In audit plugin I cannot see the event subclasses, e.g.MYSQL_AUDIT_GENERAL_ERROR General audit API (MYSQL_AUDIT_GENERAL_CLASS) didn't expose event subclass to plugins. This patch exposes event subclass to plugins via struct mysql_event_general::event_subclass. This change is not compatible with existing general audit plugins. Audit interface major version has been incremented.	16 years ago
Mats Kindahl	e409d6f69c	WL#5030: Split and remove mysql_priv.h This patch: - Moves all definitions from the mysql_priv.h file into header files for the component where the variable is defined - Creates header files if the component lacks one - Eliminates all include directives from mysql_priv.h - Eliminates all circular include cycles - Rename time.cc to sql_time.cc - Rename mysql_priv.h to sql_priv.h	16 years ago
Sergey Vojtovich	94098b22c0	Backport from 6.0-codebase. WL#3771 "Audit Plugin Interface" Implement new plug-in type - AUDIT New plug-in: audit_null simply increments counter for how many times it was called.	16 years ago
