This struct represents a specification of a GTID for a statement to be executed: either "AUTOMATIC", "AUTOMATIC:<tag>", "ANONYMOUS" or "TSID:GNO".
This is a POD. It has to be a POD because it is used in THD::variables.
std::size_t Gtid_specification::automatic_to_string | ( | char * | buf | ) | const |
Prints automatic tag specification to the given buffer.
[in,out] | buf | Buffer to write to, must be allocated |
|
inline |
Print this Gtid_specification to the trace file if debug is enabled; no-op otherwise.
|
inline |
Return true if this Gtid_specification is a ASSIGNED_GTID with the same TSID, GNO as 'other_gtid'.
|
inline |
Return true if this Gtid_specification is equal to 'other'.
Tag Gtid_specification::generate_tag | ( | ) | const |
Returns tag object generated from internal tag data.
|
inline |
Helper function indicating whether this is an assigned GTID.
|
inline |
Helper function indicating whether this is to-be-generated GTID.
true | This GTID will be generated |
false | Other type of the GTID |
|
inlinestatic |
Helper function indicating whether this is to-be-generated GTID.
[in] | type | Type of the GTID |
true | This GTID will be generated |
false | Other type of the GTID |
bool Gtid_specification::is_automatic_tagged | ( | ) | const |
Helper function indicating whether this is to-be-generated GTID with a tag assigned.
true | This GTID will be generated with assigned tag |
false | Other type of the GTID |
|
static |
Returns true if the given string is a tagged Gtid_specification.
[in] | text | Textual representation of the GTID specification |
|
inline |
Helper function indicating whether this is an undefined GTID.
|
static |
Returns true if the given string is a valid Gtid_specification.
[in] | text | Textual representation of the GTID specification |
Return_status Gtid_specification::parse | ( | Tsid_map * | tsid_map, |
const char * | text | ||
) |
Parses the given string and stores in this Gtid_specification.
tsid_map | tsid_map to use when converting TSID to a sidno. |
text | The text to parse |
|
inline |
Debug only: print this Gtid_specification to stdout.
|
inline |
Set the type to ASSIGNED_GTID and TSID, GNO to the given Gtid.
gtid_param GTID to copy from
void Gtid_specification::set | ( | const Gtid_specification & | other | ) |
Copy spec from other.
[in] | other | Pattern to copy from |
Set the type to ASSIGNED_GTID and SIDNO, GNO to the given values.
|
inline |
Set the type to ANONYMOUS_GTID.
|
inline |
Set the type to AUTOMATIC_GTID.
|
inline |
Set the type to NOT_YET_DETERMINED_GTID.

int Gtid_specification::to_string | ( | const Tsid & | tsid, |
char * | buf | ||
) | const |
Writes this Gtid_specification to the given string buffer.
tsid | TSID to use if the type of this Gtid_specification is ASSIGNED_GTID. Can be NULL if this Gtid_specification is ANONYMOUS_GTID or AUTOMATIC_GTID. | |
[out] | buf | The buffer |
The | number of characters written. |
int Gtid_specification::to_string | ( | const Tsid_map * | tsid_map, |
char * | buf, | ||
bool | need_lock = false |
||
) | const |
Writes this Gtid_specification to the given string buffer.
tsid_map | Tsid_map to use if the type of this Gtid_specification is ASSIGNED_GTID. | |
[out] | buf | The buffer |
need_lock | If true, this function acquires global_tsid_lock before looking up the sidno in tsid_map, and then releases it. If false, this function asserts that the lock is held by the caller. |
The | number of characters written. |
Tag_plain Gtid_specification::automatic_tag |
Tag defined by the user while specifying GTID_NEXT="AUTOMATIC:TAG".
We must store here the information about tag, because automatic tagged GTID does not have sidno assigned
Gtid Gtid_specification::gtid |
The GTID: { SIDNO, GNO } if type == GTID; { 0, 0 } if type == AUTOMATIC or ANONYMOUS.
