<p>can_comment_on_post($observer_xchan,$item);</p>
<p>This function examines the comment_policy attached to an item and decides if the current observer has sufficient privileges to comment. This will normally be called on a remote site where <a class="el" href="permissions_8php.html#a67ada9ed51e77885b6b0f6a28cee1835">perm_is_allowed()</a> will not be suitable because the post owner does not have a local channel_id. Generally we should look at the item - in particular the author['book_flags'] and see if ABOOK_FLAG_SELF is set. If it is, you should be able to use perm_is_allowed( ... 'post_comments'), and if it isn't you need to call <a class="el" href="items_8php.html#a1e75047cf175aaee8dd16aa761913ff9">can_comment_on_post()</a> We also check the comments_closed date/time on the item if this is set. </p>

<p>consume_feed - process atom feed and update anything/everything we might need to update</p>
<p>$xml = the (atom) feed to consume - RSS isn't as fully supported but may work for simple feeds.</p>
<p>$importer = the contact_record (joined to user_record) of the local user who owns this relationship. It is this person's stuff that is going to be updated. $contact = the person who is sending us stuff. If not set, we MAY be processing a "follow" activity from an external network and MAY create an appropriate contact record. Otherwise, we MUST have a contact record. $hub = should we find a hub declation in the feed, pass it back to our calling process, who might (or might not) try and subscribe to it. $datedir sorts in reverse order $pass - by default ($pass = 0) we cannot guarantee that a parent item has been imported prior to its children being seen in the stream unless we are certain of how the feed is arranged/ordered. With $pass = 1, we only pull parent items out of the stream. With $pass = 2, we only pull children (comments/likes).</p>
<p>So running this twice, first with pass 1 and then with pass 2 will do the right thing regardless of feed ordering. This won't be adequate in a fully-threaded model where comments can have sub-threads. That would require some massive sorting to get all the feed items into a mostly linear ordering, and might still require recursion. </p>

<p>Sourced and tag-delivered posts are re-targetted for delivery to the connections of the channel receiving the post. This starts the second delivery chain, by resetting permissions and ensuring that ITEM_UPLINK is set on the parent post, and storing the current owner_xchan as the source_xchan. We'll become the new owner. If called without $parent, this <em>is</em> the parent post. </p>

<p>A "union" is a message which our channel has sourced from another channel. This sets up a second delivery chain just like forum tags do. Find out if this is a source-able post.</p>
<p>Now we've got those out of the way. Let's see if this is a post that's tagged for re-delivery</p>

<p>can_comment_on_post($observer_xchan,$item);</p>
<p>This function examines the comment_policy attached to an item and decides if the current observer has sufficient privileges to comment. This will normally be called on a remote site where <a class="el" href="permissions_8php.html#a67ada9ed51e77885b6b0f6a28cee1835">perm_is_allowed()</a> will not be suitable because the post owner does not have a local channel_id. Generally we should look at the item - in particular the author['book_flags'] and see if ABOOK_FLAG_SELF is set. If it is, you should be able to use perm_is_allowed( ... 'post_comments'), and if it isn't you need to call <a class="el" href="items_8php.html#a1e75047cf175aaee8dd16aa761913ff9">can_comment_on_post()</a> We also check the comments_closed date/time on the item if this is set. </p>

It is this person's stuff that is going to be updated. $contact = the person who is sending us stuff. If not set, we MAY be processing a "follow" activity from an external network and MAY create an appropriate contact record. Otherwise, we MUST have a contact record. $hub = should we find a hub declation in the feed, pass it back to our calling process, who might (or might not) try and subscribe to it. $datedir sorts in reverse order $pass - by default ($pass = 0) we cannot guarantee that a parent item has been imported prior to its children being seen in the stream unless we are certain of how the feed is arranged/ordered. With $pass = 1, we only pull parent items out of the stream. With $pass = 2, we only pull children (comments/likes).</p>
<p>So running this twice, first with pass 1 and then with pass 2 will do the right thing regardless of feed ordering. This won't be adequate in a fully-threaded model where comments can have sub-threads. That would require some massive sorting to get all the feed items into a mostly linear ordering, and might still require recursion. </p>
