Data Structure Documentation

◆ unlang_child_request_t

struct unlang_child_request_t

Each child has a state, a number, a request, and a count of their siblings.

Definition at line 61 of file child_request_priv.h.

Collaboration diagram for unlang_child_request_t:

Data Fields
struct unlang_child_request_t.config	config
char const *	name	Cache the request name.
int	num	The child number.
request_t *	request	Child request. The actual request the child will run.
struct unlang_child_request_t.result	result
unsigned int *	sibling_count	Number of siblings. as a child completes, it decrements this number. once it reaches zero, the parent is signalled to resume.
unlang_child_request_state_t	state	State of the child.

◆ unlang_child_request_t.config

struct unlang_child_request_t.config

Definition at line 73 of file child_request_priv.h.

Data Fields
bool	free_child
void const *	session_unique_ptr	Session unique ptr identifier. If not NULL, the child's session data will be stored in the parent, and be restored during a later request.

◆ unlang_child_request_t.result

struct unlang_child_request_t.result

Definition at line 80 of file child_request_priv.h.

Data Fields
rlm_rcode_t *	p_result	If not NULL, write the rcode here too.
int	priority	Priority of the highest frame on the stack of the child.
rlm_rcode_t	rcode	Where to store the result of the child.

Enumeration Type Documentation

◆ unlang_child_request_state_t

enum unlang_child_request_state_t

Parallel child states.

Enumerator
CHILD_INIT	Initial state, has no request allocated.
CHILD_RUNNABLE	Running/runnable. The request is currently running, or is yielded but runnable.
CHILD_EXITED	Child has run to completion, and is waiting to be reaped.
CHILD_DETACHED	Child has detached, we can't signal it or communicate with it anymore. It will be freed by the interpreter when it completes.
CHILD_CANCELLED	Child was cancelled. The request is still available, but the result from it should not be used and it should be free by the parent.
CHILD_DONE	The child has been processed by the parent the request should still exist, and should be freed.
CHILD_FREED	The child has been freed. The request is no longer available, and should not be used. this is mostly for debugging purposes.

Definition at line 35 of file child_request_priv.h.

Function Documentation

◆ unlang_child_request_init()

int unlang_child_request_init	(	TALLOC_CTX *	ctx,
		unlang_child_request_t *	out,
		request_t *	child,
		rlm_rcode_t *	p_result,
		unsigned int *	sibling_count,
		void const *	unique_session_ptr,
		bool	free_child
	)

Initialize a child request.

This initializes the child request result and configuration structure, and pushes a resumption frame onto the child's stack.

Parameters

[in]	ctx	Memory to use for any additional memory allocated to the unlang_child_request_t.
[out]	out	Child request to initialize.
[in]	child	The child request to initialize.
[in]	p_result	Where to write out the rcode from the child.
[in,out]	sibling_count	If non-null the bumber of siblings. This is incremented for each child created.
[in]	unique_session_ptr	Unique session pointer for this child. If NULL session data won't be stored/restored for the child.
[in]	free_child	Free the child when done?

Returns

0 on success.
-1 on failure.
