)

Member Function Documentation

◆ do_apply_event()

int Gtid_log_event::do_apply_event ( Relay_log_info const *  rli)
overridevirtual

Primitive to apply an event to the database.

This is where the change to the database is made.

Note
The primitive is protected instead of private, since there is a hierarchy of actions to be performed in some cases.
See also
Format_description_log_event::do_apply_event()
Parameters
rliPointer to relay log info structure
Return values
0Event applied successfully
errnoError code if event application failed

Set the original/immediate server version. It will be set to UNKNOWN_SERVER_VERSION if the event does not contain such information.

Reimplemented from Log_event.

◆ do_shall_skip()

Log_event::enum_skip_reason Gtid_log_event::do_shall_skip ( Relay_log_info rli)
overridevirtual

Decide if this event shall be skipped or not and the reason for skipping it.

The default implementation decide that the event shall be skipped if either:

  • the server id of the event is the same as the server id of the server and rli->replicate_same_server_id is true, or
  • if rli->slave_skip_counter is greater than zero.
See also
do_apply_event
do_update_pos
Return values
Log_event::EVENT_SKIP_NOTThe event shall not be skipped and should be applied.
Log_event::EVENT_SKIP_IGNOREThe event shall be skipped by just ignoring it, i.e., the slave skip counter shall not be changed. This happends if, for example, the originating server id of the event is the same as the server id of the slave.
Log_event::EVENT_SKIP_COUNTThe event shall be skipped because the slave skip counter was non-zero. The caller shall decrease the counter by one.

Reimplemented from Log_event.

◆ do_update_pos()

int Gtid_log_event::do_update_pos ( Relay_log_info rli)
overridevirtual

Advance relay log coordinates.

This function is called to advance the relay log coordinates to just after the event. It is essential that both the relay log coordinate and the group log position is updated correctly, since this function is used also for skipping events.

Normally, each implementation of do_update_pos() shall:

  • Update the event position to refer to the position just after the event.
  • Update the group log position to refer to the position just after the event if the event is last in a group
Parameters
rliPointer to relay log info structure
Return values
0Coordinates changed successfully
errnoError code if advancing failed (usually just 1). Observe that handler errors are returned by the do_apply_event() function, and not by this one.

Reimplemented from Log_event.

◆ get_data_size()

size_t Gtid_log_event::get_data_size ( )
inlineoverridevirtual

Reimplemented from Log_event.

◆ get_event_length()

size_t Gtid_log_event::get_event_length ( )
inline

◆ get_gno()

rpl_gno Gtid_log_event::get_gno ( ) const
inline

Return the GNO for this GTID.

◆ get_sid()

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.

◆ get_sidno() [1/2]

rpl_sidno Gtid_log_event::get_sidno ( bool  need_lock)

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_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.

◆ get_sidno() [2/2]

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_mapThe sid_map to use.
Return values
SIDNOif successful.
negativeif adding SID to sid_map causes an error.

◆ get_type()

enum_gtid_type Gtid_log_event::get_type ( ) const
inline

Return the gtid type for this Gtid_log_event: this can be either ANONYMOUS_GTID, AUTOMATIC_GTID, or ASSIGNED_GTID.

◆ pack_info()

int Gtid_log_event::pack_info ( Protocol protocol)
overridevirtual

Stores a string representation of this event in the Protocol.

This is used by SHOW BINLOG EVENTS.

Return values
0success
nonzeroerror

Reimplemented from Log_event.

◆ set_trx_length_by_cache_size()

void Gtid_log_event::set_trx_length_by_cache_size ( ulonglong  cache_size,
bool  is_checksum_enabled = false,
int  event_counter = 0 
)

Set the transaction length information based on binlog cache size.

Note that is_checksum_enabled and event_counter are optional parameters. When not specified, the function will assume that no checksum will be used and the informed cache_size is the final transaction size without considering the GTID event size.

The high level formula that will be used by the function is:

trx_length = cache_size + cache_checksum_active * cache_events * CRC32_payload + gtid_length + cache_checksum_active * CRC32_payload; // For the GTID.

Parameters
cache_sizeThe size of the binlog cache in bytes.
is_checksum_enabledIf checksum will be added to events on flush.
event_counterThe amount of events in the cache.

◆ to_string()

size_t Gtid_log_event::to_string ( char *  buf) const
private

Used internally by both print() and pack_info().

◆ write_body_to_memory()

uint32 Gtid_log_event::write_body_to_memory ( uchar buff)
private

Writes the body to the given memory buffer.

This is an auxiliary function used by write_to_memory.

Parameters
[in,out]buffBuffer to which the data will be written.
Returns
The number of bytes written, i.e., If the transaction did not originated on this server Gtid_event::IMMEDIATE_COMMIT_TIMESTAMP_LENGTH. else FULL_COMMIT_TIMESTAMP_LENGTH.

◆ write_data_body()

bool Gtid_log_event::write_data_body ( Basic_ostream ostream)
overrideprivatevirtual

Reimplemented from Log_event.

◆ write_data_header()

bool Gtid_log_event::write_data_header ( Basic_ostream ostream)
overrideprivatevirtual

Writes the post-header to the given output stream.

This is an auxiliary function typically used by the write() member function.

Parameters
ostreamThe output stream to write to.
Return values
trueError.
falseSuccess.

Reimplemented from Log_event.

◆ write_post_header_to_memory()

uint32 Gtid_log_event::write_post_header_to_memory ( uchar buffer)
private

Writes the post-header to the given memory buffer.

This is an auxiliary function used by write_to_memory.

Parameters
[in,out]bufferBuffer to which the post-header will be written.
Returns
The number of bytes written, i.e., always Gtid_log_event::POST_HEADER_LENGTH.

◆ write_to_memory()

uint32 Gtid_log_event::write_to_memory ( uchar buf)
inline

Writes this event to a memory buffer.

Parameters
bufThe event will be written to this buffer.
Returns
the number of bytes written, i.e., always LOG_EVENT_HEADER_LEN + Gtid_log_event::POST_HEADEr_LENGTH.
