static

Simple pair building callback for use with tmpl_dcursors.

Which always appends the new pair to the tail of the list since it is only called when no matching pairs were found when walking the list.

Note that this function is called for all intermediate nodes which are built!

Parameters

[in]	parent	to allocate new pair within.
[in,out]	cursor	to append new pair to.
[in]	da	of new pair.
[in]	uctx	unused.

Returns

• newly allocated fr_pair_t.
• NULL on error.

unlang_edit_push()

int unlang_edit_push	(	request_t *	request,
		bool *	success,
		fr_edit_list_t *	el,
		map_list_t const *	map_list
	)

Push a map onto the stack for edit evaluation.

If the "success" variable returns "false", the caller should call fr_edit_list_abort().

If the "success" variable returns "true", the caller can free the edit list (or rely on talloc to do that) and the transaction will be finalized.

Parameters

[in]	request	The current request.
[out]	success	Whether or not the edit succeeded
[in]	el	Edit list which can be used to apply multiple edits
[in]	map_list	The map list to process

static

Execute an update block.

Update blocks execute in two phases, first there's an evaluation phase where each input map is evaluated, outputting one or more modification maps. The modification maps detail a change that should be made to a list in the current request. The request is not modified during this phase.

The second phase applies those modification maps to the current request. This re-enables the atomic functionality of update blocks provided in v2.x.x. If one map fails in the evaluation phase, no more maps are processed, and the current result is discarded.
