<li>Improved the <a href="/api/updates">updates</a> documentation, specifically:<ul>
|
||||
<li>Clarified that <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> does <em>not</em> have to be invoked on startup for all channels, as it will be automatically triggered (only for channels that need catching up) by a set of <a href="/constructor/updateChannelTooLong">updateChannelTooLong</a> updates that will be returned by <a href="/method/updates.getDifference">updates.getDifference</a> (that <em>does</em> need to be called on startup).</li>
|
||||
<li>Clarified that <a href="/api/updates#subscribing-to-updates-of-channels-supergroups">users should short-poll updates.getChannelDifference for currently opened channels/supergroups (including subscribed ones) »</a>.</li>

<li>Clarified that <a href="/api/updates#subscribing-to-updates-of-channels-supergroups">users should short-poll updates.getChannelDifference for currently opened channels/supergroups (including subscribed ones, max 10 overall) »</a>.</li>
|
||||
<li>Clarified that <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> should not be short-polled via <code>timeout</code> by bots, or if the user is currently not viewing the channel/supergroup.</li>
|

<li>Clarified that clients should limit to 10 the maximum number of concurrent <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> calls.</li>

<p>For performance reasons and for better user experience, client can set maximum gap size to be filled: <code>pts_total_limit</code> parameter of <a href="/method/updates.getDifference">updates.getDifference</a> and <code>limit</code> parameter for <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> can be used.</p>
|
||||
<p>If the gap is too large and there are too many updates to fetch, a <code>*TooLong</code> constructor will be returned. In this case, the client must <a href="#fetching-state">re-fetch the state</a>, re-start fetching updates from that state and follow the instructions that can be found <a href="/constructor/updates.channelDifferenceTooLong">here</a>.</p>
|
||||
<p>It is recommended to use limit <code>10-100</code> for channels and <code>1000-10000</code> otherwise.</p>
|
||||
<p>Limit the maximum number of concurrent <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> calls to 10. </p>
|
||||
<p>Do not re-invoke <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> if the returned difference is <code>final</code>, unless <a href="#subscribing-to-updates-of-channels-supergroups">the user has opened the channel/supergroup</a> or <a href="#subscribing-to-updates-of-channels-supergroups-we-havent-joined">we're fetching updates from a channel/supergroup we're not a member of</a>. </p>

<p>Do not re-invoke <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> if the returned difference is <code>final</code>, unless <a href="#subscribing-to-updates-of-channels-supergroups">the user has opened the channel/supergroup »</a>. </p>

<p>The API will automatically send passive updates (i.e. as standalone <a href="/type/Updates">Updates</a> constructors in the socket) for channels/supergroups the user/bot is a member of. </p>
|
||||
<p>The API will automatically send passive updates (i.e. as standalone <a href="/type/Updates">Updates</a> constructors in the socket) for channels/supergroups the user/bot is a member of. </p>
|
||||
<p>However, clients (user accounts only) should also additionally invoke <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> periodically for channels and supergroups the user is currently viewing (i.e. explicitly opened channels/supergroups in one or more tabs/windows). </p>
|
||||
<p>If the returned difference is non-<code>final</code>, the method should be called immediately with the new parameters <a href="#recovering-gaps">as usual</a>. </p>
|
||||
<p>If the returned difference is <code>final</code>, and the user is still viewing the messages of the supergroup/channel (i.e. via distinct tabs/windows), <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> should be re-invoked after <code>timeout</code> seconds (if the flag is specified, otherwise after 1 second). </p>
|
||||
<p>Clients should stop <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> polling once the user closes the channel/supergroup: this will not interrupt reception of passive updates, as long as the user is subscribed to the channel/supergroup. </p>
|
||||
<p>Note that the shortpolling mechanism described above is also used to <a href="#subscribing-to-updates-of-channels-supergroups-we-havent-joined">enable passive delivery of updates from a channel/supergroup we're not a member of</a>. </p>

<h3><a class="anchor" href="#subscribing-to-updates-of-channels-supergroups-we-havent-joined" id="subscribing-to-updates-of-channels-supergroups-we-havent-joined" name="subscribing-to-updates-of-channels-supergroups-we-havent-joined"><i class="anchor-icon"></i></a>Subscribing to updates of channels/supergroups we haven't joined</h3>
|
||||
<p>Clients may ask the API to passively send them updates for <a href="/api/channel">channels/supergroups</a> they haven't joined, by simply making a <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> query. </p>
|
||||
<p>If the specified channel or supergroup is public, or is private but temporarily available for a limited time thanks to a <a href="/constructor/chatInvitePeek">chatInvitePeek</a>, the API will start passively sending updates (i.e. as standalone <a href="/type/Updates">Updates</a> constructors in the socket, as is already the case for normal channels/supergroups we've already joined) to all logged-in sessions, as long as any of the sessions continues to periodically invoke <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> every <code>timeout</code> seconds (returned by the method, or every second if the <code>timeout</code> flag is absent from the return value of the method, or immediately with the new parameters if the returned difference is non-<code>final</code>). </p>
|
||||
<p>To stop passively receiving updates, simply stop invoking <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a>, and the API will automatically stop passively sending updates after a while. </p>
|
||||
<p>This mechanism may also be used to enable <em>passive</em> reception of updates from channels or supergroups we're <em>not</em> a member of: if the specified channel or supergroup is public, or is private but temporarily available for a limited time thanks to a <a href="/constructor/chatInvitePeek">chatInvitePeek</a>, the API will start passively sending updates (i.e. as standalone <a href="/type/Updates">Updates</a> constructors in the socket, as is already the case for normal channels/supergroups we've already joined) to all logged-in sessions, as long as any of the sessions continues to periodically invoke <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> every <code>timeout</code> seconds (returned by the method, or every second if the <code>timeout</code> flag is absent from the return value of the method, or immediately with the new parameters if the returned difference is non-<code>final</code>). </p>
|
||||
<p>Clients should stop <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> polling once the user closes the channel/supergroup: the API will continue emitting passive updates <strong>only</strong> if the user is a member of the channel/supergroup. </p>
|
||||
<p>Clients should also limit to 10 the maximum number of channels/supergroups shortpolled using the above mechanism (i.e. if the user opens 11 windows on 11 different channels, shortpoll with <a href="/method/updates.getChannelDifference">updates.getChannelDifference</a> only the first 10). </p>

<p>Implementations also have to take care to postpone updates received via the socket while filling gaps in the event and Update sequences, as well as avoid filling gaps in the same sequence.</p>
