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.

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.

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.

need_lockIf 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:
SIDNOif successful
negativeif adding SID to global_sid_map causes an error.
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.

sid_mapThe sid_map to use.
Return values:
SIDNOif successful. if adding SID to sid_map causes an error.
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.
