Function Documentation

◆ check_and_apply_resource_grp()

static bool check_and_apply_resource_grp ( THD thd,
ulonglong  thread_id,
resourcegroups::Resource_group resource_group,
bool  error 
)
inlinestatic

Check if resource group controls can be applied to thread identified by PFS thread id.

Apply the controls to thread if the checks were successful.

Parameters
thdTHD context
thread_idThread id of the thread.
resource_groupPointer to resource group.
errorLog error so that error is returned to client.
Returns
true if the function fails else false.

◆ check_and_load_resource_group()

static resourcegroups::Resource_group * check_and_load_resource_group ( THD thd,
const LEX_CSTRING resource_group_name 
)
inlinestatic

Check if a resource group specified by a name is present in memory.

Load a resource group from the Data Dictionary if it missed in memory.

Parameters
thdTHD context.
resource_group_nameResource group name.
Returns
nullptr in case of error, else return a pointer to an instance of class resourcegroups::Resource_group.
Note
in case nullptr is returned an error is set in Diagnostics_area.

◆ check_resource_group_set_privilege()

static bool check_resource_group_set_privilege ( Security_context sctx)
static

Check if user has sufficient privilege to exercise SET RESOURCE GROUP.

Parameters
sctxPointer to security context.
Returns
true if sufficient privilege exists for SET RESOURCE GROUP else false.
