- Changed ER(ER_...) to ER_THD(thd, ER_...) when thd was known or if there was many calls to current_thd in the same function. - Changed ER(ER_..) to ER_THD_OR_DEFAULT(current_thd, ER...) in some places where current_thd is not necessary defined. - Removing calls to current_thd when we have access to thd Part of this is optimization (not calling current_thd when not needed), but part is bug fixing for error condition when current_thd is not defined (For example on startup and end of mysqld) Notable renames done as otherwise a lot of functions would have to be changed: - In JOIN structure renamed: examined_rows -> join_examined_rows record_count -> join_record_count - In Field, renamed new_field() to make_new_field() Other things: - Added DBUG_ASSERT(thd == tmp_thd) in Item_singlerow_subselect() just to be safe. - Removed old 'tab' prefix in JOIN_TAB::save_explain_data() and use members directly - Added 'thd' as argument to a few functions to avoid calling current_thd.
