* @file mod/dfrn_confirm.php
|
|
* @brief Module: dfrn_confirm
|
|
* Purpose: Friendship acceptance for DFRN contacts
|
|
*
|
|
* There are two possible entry points and three scenarios.
|
|
*
|
|
* 1. A form was submitted by our user approving a friendship that originated elsewhere.
|
|
* This may also be called from dfrn_request to automatically approve a friendship.
|
|
*
|
|
* 2. We may be the target or other side of the conversation to scenario 1, and will
|
|
* interact with that process on our own user's behalf.
|
|
*
|
|
* @see PDF with dfrn specs: https://github.com/friendica/friendica/blob/master/spec/dfrn2.pdf
|
|
* You also find a graphic which describes the confirmation process at
|
|
* https://github.com/friendica/friendica/blob/master/spec/dfrn2_contact_confirmation.png
