list_mod_apply()

static unlang_action_t list_mod_apply ( rlm_rcode_t *  p_result, request_t *  request  )

static

Apply a list of modifications on one or more fr_pair_t lists.

Parameters

[in]	request	The current request.
[out]	p_result	The rcode indicating what the result of the operation was.

Returns

• UNLANG_ACTION_CALCULATE_RESULT changes were applied.
• UNLANG_ACTION_PUSHED_CHILD async execution of an expansion is required.

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.
