Annamalai Gurusami ad84fb5c37 Bug #13117023: Innodb increments handler_read_key when it should not ... The counter handler_read_key (SSV::ha_read_key_count) is incremented incorrectly. The mysql server maintains a per thread system_status_var (SSV) object. This object contains among other things the counter SSV::ha_read_key_count. The purpose of this counter is to measure the number of requests to read a row based on a key (or the number of index lookups). This counter was wrongly incremented in the ha_innobase::innobase_get_index(). The fix removes this increment statement (for both innodb and innodb_plugin). The various callers of the innobase_get_index() was checked to determine if anybody must increment this counter (if they first call innobase_get_index() and then perform an index lookup). It was found that no caller of innobase_get_index() needs to worry about the SSV::ha_read_key_count counter.		2011-12-13 14:26:12 +05:30
