Function Documentation

reset_start_time_for_sp()

static void reset_start_time_for_sp ( THD *  thd )

static

Helper function which operates on a THD object to set the query start_time to the current time.

Parameters

thd	Thread context.

sp_update_sp_used_routines()

static void sp_update_sp_used_routines ( malloc_unordered_map< std::string, Sroutine_hash_entry * > *  dst, const malloc_unordered_map< std::string, Sroutine_hash_entry * > &  src  )

static

Merge contents of two hashes representing sets of routines used by statements or by other routines.

Parameters

dst	hash to which elements should be added
src	hash from which elements merged

Note

This procedure won't create new Sroutine_hash_entry objects, instead it will simply add elements from source to destination hash. Thus time of life of elements in destination hash becomes dependent on time of life of elements from source hash. It also won't touch lists linking elements in source and destination hashes.
