Detailed Description

Private interface for the server (declarations).

Definition in file pfs_server.h.

Function Documentation

int add_pfs_instr_to_array	(	const char *	name,
		const char *	value
	)

Process one PFS_INSTRUMENT configuration string.

Process one performance_schema_instrument configuration string. Isolate the instrument name, evaluate the option value, and store them in a dynamic array. Return 'false' for success, 'true' for error.

Parameters

name	Instrument name
value	Configuration option: 'on', 'off', etc.

Returns

0 for success, non zero for errors

Definition at line 245 of file pfs_server.cc.

void check_performance_schema

(

)

Check that the performance schema tables have the expected structure. Discrepancies are written in the server log, but are not considered fatal, so this function does not return an error code:

• some differences are compatible, and should not cause a failure
• some differences are not compatible, but then the DBA needs an operational server to be able to DROP+CREATE the tables with the proper structure, as part of the initial server installation or during an upgrade. In case of discrepancies, later attempt to perform DML against the performance schema will be rejected with an error.
