Constructor & Destructor Documentation

Gtid_log_event::Gtid_log_event	(	THD *	thd_arg,
		bool	using_trans,
		const Gtid_specification *	spec = NULL
	)

Create a new event using the GTID from the given Gtid_specification, or from @SESSION.GTID_NEXT if spec==NULL.

Definition at line 13146 of file log_event.cc.

Here is the call graph for this function:

Member Function Documentation

const rpl_sid* Gtid_log_event::get_sid ( ) const

inline

Return the SID for this GTID. The SID is shared with the Log_event so it should not be modified.

Definition at line 4921 of file log_event.h.

rpl_sidno Gtid_log_event::get_sidno ( bool  need_lock )

inline

Return the SIDNO relative to the global sid_map for this GTID.

This requires a lookup and possibly even update of global_sid_map, hence global_sid_lock must be held. If global_sid_lock is not held, the caller must pass need_lock=true. If there is an error (e.g. out of memory) while updating global_sid_map, this function returns a negative number.

Parameters

need_lock

If true, the read lock on global_sid_lock is acquired and released inside this function; if false, the read lock or write lock must be held prior to calling this function.

Return values

SIDNO	if successful
negative	if adding SID to global_sid_map causes an error.

Definition at line 4937 of file log_event.h.

Here is the call graph for this function:

Here is the caller graph for this function:

rpl_sidno Gtid_log_event::get_sidno ( Sid_map *  sid_map )

inline

Return the SIDNO relative to the given Sid_map for this GTID.

This assumes that the Sid_map is local to the thread, and thus does not use locks.

Parameters

sid_map

The sid_map to use.

Return values

SIDNO

if successful. if adding SID to sid_map causes an error.

Definition at line 4961 of file log_event.h.

Here is the call graph for this function:

enum_group_type Gtid_log_event::get_type ( ) const

inline

Return the group type for this Gtid_log_event: this can be either ANONYMOUS_GROUP, AUTOMATIC_GROUP, or GTID_GROUP.

Definition at line 4914 of file log_event.h.

Member Data Documentation

const int Gtid_log_event::POST_HEADER_LENGTH

static

Initial value:

    ENCODED_FLAG_LENGTH + ENCODED_SID_LENGTH + ENCODED_GNO_LENGTH

Total length of post header.

Definition at line 4988 of file log_event.h.
