|
* xchan is your connection
|
|
* We will load their friend list, and store in xlink_xchan your connection hash and xlink_link the hash for each connection
|
|
* If xchan isn't provided we will load the list of people from url who have indicated they are willing to be friends with
|
|
* new folks and add them to xlink with no xlink_xchan.
|
|
*
|
|
* Old behaviour: (documentation only):
|
|
* Given a contact-id (minimum), load the PortableContacts friend list for that contact,
|
|
* and add the entries to the gcontact (Global Contact) table, or update existing entries
|
|
* if anything (name or photo) has changed.
|
|
* We use normalised urls for comparison which ignore http vs https and www.domain vs domain
|
|
*
|
|
* Once the global contact is stored add (if necessary) the contact linkage which associates
|
|
* the given uid, cid to the global contact entry. There can be many uid/cid combinations
|
|
* pointing to the same global contact id.
|
|
*
