Milestone: Actor colour theme plugin
|
|
</title><description><![CDATA[
|
|
|
|
<p>Actors are now able to set their own colours, through a brand new plugin: "Oomox".
|
|
Those accustomed to customising their own desktop should know where the name comes from ;)</p>
|
|
|
|
<h2>Here's how it works!</h2>
|
|
|
|
<p>The Oomox plugin main class catches the "PopulateProfileSettingsTabs" event upon visiting user panel.</p>
|
|
|
|
<pre><code>public function onPopulateProfileSettingsTabs(Request $request, array &$tabs): bool
|
|
{
|
|
$tabs[] = [
|
|
'title' => 'Light theme colours',
|
|
'desc' => 'Change the theme colours.',
|
|
'controller' => C\Oomox::oomoxSettingsLight($request),
|
|
];
|
|
|
|
$tabs[] = [
|
|
'title' => 'Dark theme colours',
|
|
'desc' => 'Change the theme colours.',
|
|
'controller' => C\Oomox::oomoxSettingsDark($request),
|
|
];
|
|
|
|
return Event::next;
|
|
}
|
|
</code></pre>
|
|
|
|
<p>As made evident by the code, two new tabs are added to profile settings, light and dark theme colours.
|
|
Since the page styling follows the system theme, actors may want to style each theme differently, therefore they are treated separately.</p>
|
|
|
|
<p>The actor's defined colours are then saved in the respective entity and cached.
|
|
Finally, the colour preferences are used to render the corresponding CSS file which defines the various colour variables used:</p>
|
|
|
|
<pre><code>public function oomoxCSS(): Response
|
|
{
|
|
$user = Common::ensureLoggedIn();
|
|
|
|
$oomox_table = PluginOomox::getEntity($user);
|
|
if (is_null($oomox_table)) {
|
|
throw new ClientException(_m('No custom colours defined', 404));
|
|
}
|
|
|
|
$content = Formatting::twigRenderFile('/oomox/root_override.css.twig', ['oomox' => $oomox_table]);
|
|
return new Response($content, status: 200, headers: ['content-type' => 'text/css']);
|
|
}
|
|
</code></pre>
|
|
|
|
<p>Please note, upon rendering for the first time, page render may be blocked until the resulting file is served. Nonetheless, subsequent page renders
|
|
won't experience the issue again. That is, if the file is cached by the browser.</p>
|
|
|
|
<h2>How it looks</h2>
|
|
|
|
<p>Tabs added using the "PopulateProfileSettingsTabs" event:
|
|
<img src="assets/actor_colour_theme_plugin/settings_change_theme_colours.png" alt="User panel Oomox sections" title="" /></p>
|
|
|
|
<p>Changing the dark theme colours!
|
|
<img src="assets/actor_colour_theme_plugin/settings_change_theme_colours3.png" alt="Dark theme colours selection" title="" /></p>
|
|
|
|
<p>The result of given changes, please note it's no longer a 'dark' theme.
|
|
Given a valid colour, it's the actor's responsibility whether or not the colours make sense. So, go wild!

Milestone: ActivityPub
|
|
</title><description><![CDATA[
|
|
|
|
<p><a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/plugins/ActivityPub">ActivityPub Plugin source</a>.</p>
|
|
|
|
<p>This milestone could be just this, what's different from any other ActivityPub
|
|
plugin? How is it better than v2's?</p>
|
|
|
|
<p>It's better in how it's organised and extensible. See the examples below to have
|
|
an idea.</p>
|
|
|
|
<p>To extend an Activity properties you do:</p>
|
|
|
|
<pre><code>public function onActivityPubValidateActivityStreamsTwoData(string $type_name, array &$validators): bool {
|
|
if ($type_name === '{Type}') {
|
|
$validators['attribute'] = myValidator::class;
|
|
}
|
|
return Event::next;
|
|
}
|
|
</code></pre>
|
|
|
|
<p>The Validator should be of the form:</p>
|
|
|
|
<pre><code>class myValidator extends Plugin\ActivityPub\Util\ModelValidator
|
|
{
|
|
/**
|
|
* Validate Attribute's value
|
|
*
|
|
* @param mixed $value from JSON's attribute
|
|
* @param mixed $container A {Type}
|
|
* @return bool
|
|
* @throws Exception
|
|
*/
|
|
public function validate($value, $container): bool
|
|
{
|
|
// Validate that container is a {Type}
|
|
Util::subclassOf($container, Type\Extended\Object\{Type}::class, true);
|
|
|
|
return {Validation Result};
|
|
</code></pre>
|
|
|
|
<p>To act on received activities do:</p>
|
|
|
|
<pre><code>public function onActivityPubNew{Type}(&$obj): bool {
|
|
</code></pre>
|
|
|
|
<p>To add information to Activities being federated by ActivityPub do:</p>
|
|
|
|
<pre><code>public function ActivityPubAddActivityStreamsTwoData(string $type_name, &$type): bool {
|
|
</code></pre>
|
|
|
|
<p>To implement an ActivityStreams 2.0 representation do:</p>
|
|
|
|
<pre><code>public function onActivityPubActivityStreamsTwoResponse(string $route, arrray $vars, ?TypeResponse &$response = null): bool {
|
|
if ($route === '{Object route}') {
|
|
$response = ModelResponse::handle($vars[{Object}]);
|
|
return Event::stop;
|
|
}
|
|
return Event::next;
|
|
}
|
|
</code></pre>

Milestone: ActivityStreams 2.0 and WebFinger
|
|
</title><description><![CDATA[
|
|
|
|
<p>The primary use of GNU social is to access the <a href="https://blog.diogo.site/what-is-the-fediverse">free network</a>, be it ActivityWeb (ActivityPub) or Fediverse (OStatus).</p>
|
|
|
|
<p>Contrary to the original plan, we have merged <a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/nightly/modules/TheFreeNetwork">The Free Network Module</a>, <a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/nightly/plugins/WebFinger">WebFinger</a> and <a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/nightly/plugins/LRDD">LRDD</a> into a single component named <a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/components/FreeNetwork">FreeNetwork</a>. Likewise, ActivityPub and ActivityStreams 2.0 was kept the same plugin instead of separated.</p>
|
|
|
|
<h2>Understanding the organisation chosen</h2>
|
|
|
|
<p>The FreeNetwork component adds WebFinger (RFC7033) lookup and implements Link-based Resource Descriptor Discovery (LRDD) based on RFC6415, Web Host Metadata. It takes and produces both Extensible Resource Descriptor (XRD) and JSON (JavaSript Object Notation). Furthermore, and different from v2, every federation protocol will use the same distribution queue maintained by this component instead of holding its own.</p>
|
|
|
|
<p>We originally intended to have data modelling plugins that would extend the GS's "language". We then understood that it added more complexity than we wanted without any considerable advantage because we cannot dissociate data reception handling of the protocol itself.</p>
|
|
|
|
<h2>Situation Report</h2>
|
|
|
|
<p><a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/plugins/ActivityPub">ActivityPub</a> already translates between activity and entity and allows plugins to extend it (thus serving a similar purpose to data modelling and representation plugins).</p>
|
|
|
|
<p>GNU social v3 now supports <a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/src/Util/Formatting.php#L292">mentions</a>, which is a process that starts in the <a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/components/Posting/Posting.php#L197">Posting component</a>. The processing of local mentions naturally finds its entire handling here.</p>
|
|
|
|
<p>For remote ActivityPub mentions, <a href="(https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/plugins/ActivityPub/Entity/ActivitypubActor.php#L179">ActivityPub handles it aided by the FreeNetwork component</a>).</p>
|
|
|
|
<h2>Next steps</h2>
|
|
|
|
<p>We still have to port OStatus (and ActivityStreams 1.0) and implement the distribution by FreeNetwork, although the base work is done. Regarding ActivityPub, although some of it already works, expanding the existing plugins to supplement ActivityPub, and full validation isn't ready yet. We will most likely finish the implementation of the whole federation stack in the next week.</p>

Milestone: Documentation and Tests Infrastructure

<p><strong><a href="https://agile.gnusocial.rocks/doku.php?id=milestones:initial_test_documentation_infrastructure">>WIKI Milestone entry</a></strong></p>
|
|
|
|
<p>GNU social now has its documentation available in
|
|
<a href="https://docs.gnusocial.rocks/">https://docs.gnusocial.rocks/</a>. It features four
|
|
different books. These are automatically generated from the <a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/docs">source</a> using <a href="https://rust-lang.github.io/mdBook/">mdBook</a>.</p>
|
|
|
|
<blockquote>
|
|
<p>Only the development book is in an elaborated state, the other books are
|
|
holding for more ready code.</p>
|
|
</blockquote>
|
|
|
|
<p>And two of them are new:</p>
|
|
|
|
<ul>
|
|
<li>The <a href="https://docs.gnusocial.rocks/developer">Developer</a> is both intended to guide third-party plugin developers and to make it easier of contributing to the code.</li>
|
|
<li>The <a href="https://docs.gnusocial.rocks/designer">Designer</a> is the most recent of the four and came from a necessity of keeping some standardization between templates and ensuring the same principles are kept in mind when designing new themes.</li>
|
|
</ul>
|
|
|
|
<p>And two of them are updates from existing documentation:</p>
|
|
|
|
<ul>
|
|
<li>The <a href="https://docs.gnusocial.rocks/user">User</a> one is adapted
|
|
from the existing GNU social documentation for users that was provided in v2.</li>
|
|
<li>The <a href="https://docs.gnusocial.rocks/administrator">Administrator</a> one is adapted
|
|
from the "Unofficial GNU social docs" by Thomask who <a href="https://notabug.org/diogo/gnu-social/issues/246">asked us to make it official</a>.</li>
|
|
</ul>
|
|
|
|
<p>Together with the documentation we've introduced a
|
|
<a href="https://agile.gnusocial.rocks/">wiki</a>. Its purpose is to walk-through decisions,
|
|
convention, terminology. It's where we document the reasoning the development team went
|
|
through before implementing more sophisticated functionalities.</p>
|
|
|
|
<p>Finally, when the documentation doesn't explain, and to ensure the whole code
|
|
is properly tested, we have the
|
|
<a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/tests">tests</a>. And the coverage is available <a href="https://coverage.gnusocial.rocks/">here</a>. At the time of writing the coverage has 98.76% code lines tested.</p>

Milestone: Notes and Actors with languages
|
|
</title><description><![CDATA[
|
|
|
|
<p>Well, it's that, our notes now have a language attribute.</p>
|
|
|
|
<p>... All right, all right, it's not <em>just</em> it.</p>
|
|
|
|
<h2>Here's what comes with it:</h2>
|
|
|
|
<ul>
|
|
<li><a href="">Filter the streams with only the languages you know</a></li>
|
|
<li><a href="">Federate the language for a more inclusive free network</a></li>
|
|
<li><a href="">Make Tag Wrangling possible and transversal to languages</a></li>
|
|
</ul>
|
|
|
|
<h2>Here's how it looks</h2>
|
|
|
|
<p>First, the user panel section where the desired preferences are selected:
|
|
<img src="assets/notes_and_actors_with_languages/settings_language.png" alt="User panel language settings section" title="" /></p>
|
|
|
|
<p>Upon sending the previous form, the user is redirected to order their selection:
|
|
<img src="assets/notes_and_actors_with_languages/settings_language_order.png" alt="Ordering the selections made in previous page" title="" /></p>
|
|
|
|
<p>Finally, when posting the language with the highest priority is selected by default.</p>
|
|
|
|
<p>However, by accessing "Additional options", another language may be selected. The resulting
|
|
note will have the lang attribute according to it.</p>
|
|
|
|
<p>The posting widget itself:
|
|
<img src="assets/notes_and_actors_with_languages/posting_language_options.png" alt="Selecting the language of a note when posting" title="" /></p>
|
|
|
|
<h2>What does this mean?</h2>
|
|
|
|
<p>We can now show you the notes you can read, but for groups, this mean that you
|
|
can access umbrella groups and filter the feeds to see what's in your language
|
|
and even region.</p>
|
|
|
|
<p>For too long the fediverse struggled with languages, this step makes it easier
|
|
for actual internationalization of the free network.</p>
|
|
|
|

Milestone: Port Media handling from v2
|
|
</title><description><![CDATA[
|
|
|
|
<p><strong><a href="https://agile.gnusocial.rocks/doku.php?id=milestones:attachment_media_embed_handling">>WIKI Milestone entry</a></strong></p>
|
|
|
|
<p>File Storage in GNU social is used for avatars, for notes containing
|
|
attachments, and for notes containing links (in which case is an Embed preview).
|
|
Notes can be created by local users or fetched from remote actors. Filehash is
|
|
used to reduce file duplication.</p>
|
|
|
|
<p>When a user shares a Link that uses OpenGraph tags or has an OEmbed provider,
|
|
the <a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/plugins/Embed">Embed plugin</a> generates a preview for it that may contain a thumbnail.</p>
|
|
|
|
<p>When a user shares a Link to an image, the <a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/plugins/StoreRemoteMedia">StoreRemoteMedia plugin</a> can fetch the
|
|
file and make it available as an attachment, and will generate a thumbnail.</p>
|
|
|
|
<p>When an image, video, or other file type is uploaded or retrieved, an Attachment
|
|
entity is created. When a thumbnail is requested, one is generated if an
|
|
EncoderPlugin that supports the mime type is available.</p>
|
|
|
|
<p>There are two EncoderPlugins implemented:</p>
|
|
|
|
<ul>
|
|
<li><a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/plugins/ImageEncoder">ImageEncoder</a>: Allows to compress, validate, rescale, and sanitize images using VIPS.</li>
|
|
<li><a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/plugins/VideoEncoder">VideoEncoder</a>: Allows to rescale gifs using FFMpeg.</li>
|
|
</ul>
|
|
|
|
<p>Another helpful plugin is <a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/plugins/FileQuota">FileQuota</a> which ensures a user stays under the file quota.</p>
|
|
|
|
<h2>How is the code organised?</h2>
|
|
|
|
<p>There are various entities related to attachment and thumbnail handling.
|
|
The key ones are:</p>
|
|
|
|
<ul>
|
|
<li><a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/src/Entity/Attachment.php">Attachment</a></li>
|
|
<li><a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/src/Entity/AttachmentThumbnail.php">AttachmentThumbnail</a></li>
|
|
</ul>
|
|
|
|
<p>The plugins are able to act by means of the Events system, as elaborated in the
|
|
<a href="https://docs.gnusocial.rocks/developer/storage.html">documentation</a>.</p>

Milestone: Tags
|
|
</title><description><![CDATA[
|
|
|
|
<blockquote>
|
|
<p>Due to the high density of technical aspects, we decided to keep this blog
|
|
post more on the light side and focus on explaining the new functionalities.
|
|
Check our Wiki Milestone entry for all the juicy details.</p>
|
|
</blockquote>
|
|
|
|
<p><strong><a href="https://agile.gnusocial.rocks/doku.php?id=milestones:tags">>WIKI Milestone entry</a></strong></p>
|
|
|
|
<p>GNU social v2 has tags and lists. It allows you to:
|
|
- search for an <code>#hashtag</code> and see a stream of notes tagged with it;
|
|
- make lists of actors and mention them with <code>@#list_name</code>
|
|
- self tag and enter a list of people in your instance with the same self tag</p>
|
|
|
|
<p>It is limited with regards to federation of self tags and the <code>@#list_name</code> can't
|
|
target remote actors even when they are inside your list.</p>
|
|
|
|
<h2>What's new with v3?</h2>
|
|
|
|
<h3>Federated self tags</h3>
|
|
|
|
<p>We now federate self tags and lists, so that constraint from v2 was moved out of
|
|
the way.</p>
|
|
|
|
<p>In the future, the use of these tags can allow you to find people,
|
|
groups and even individual notes that have a tag you're interested in. We only
|
|
mean filtering, not magic recommendation algorithms.</p>
|
|
|
|
<h3>Tag Wrangling</h3>
|
|
|
|
<p>Proposed by <a href="https://archiveofourown.org/users/licho">@licho</a> in Tue, 02 Jun 2019 17:52:07 GMT:</p>
|
|
|
|
<blockquote>
|
|
<p>I like the tag wrangling feature of AO3, which I think would help for cases of synonymous tags like #introduction and #introductions</p>
|
|
|
|
<p>https://archiveofourown.org/wrangling_guidelines/11</p>
|
|
|
|
<p>Is it feasible for !gnusocial ? Or would it cause problems?</p>
|
|
</blockquote>
|
|
|
|
<p>The answer is <strong>yes</strong> and will be released with v3. With the addition of
|
|
<a href="(https://gnusocial.rocks/v3/milestone-notes-and-actors-with-languages.html">Languages in notes and actors</a>) there was little excuse not to be feasible.</p>
|
|
|
|
<p>Whenever you post a note containing tags, you can choose whether to
|
|
make those tags canonical. This means that, for instance, the tags
|
|
<code>#run</code> and <code>#running</code> become the 'same', meaning that when you click on
|
|
the link for the <code>#run</code> tag, you'll also see notes tagged #running. You
|
|
can opt out of the behaviour by unchecking the "Make note tags
|
|
canonical". An identical process occurs for people tags.</p>
|
|
|
|
<p>Internally, this transformation is accomplished by splitting the tag
|
|
into words and <a href="https://en.wikipedia.org/wiki/Stemming">stemming</a> each word.</p>
|
|
|
|
<h3>Related Tags</h3>
|
|
|
|
<p>In a tag feed, you can see tags that are often used together with the
|
|
one you're seeing. This can be useful, for instance, for finding other
|
|
content you'd be interested in.</p>
|
|
|
|
<h1>Improved Tag feeds</h1>
|
|
|
|
<p>When you click on a tag, be it a note tag or a person tag, you'll see
|
|
a feed of notes/people with that tag. You can also edit the feeds you
|
|
see in your left panel, so you can follow a given tag.</p>
|
|
|
|
<h1>Mute Self Tags and Note Tags</h1>
|
|
|
|
<p>If you don't like seeing a given tag in your feeds, for whatever
|
|
reason, you can choose to mute it. You can mute a note tag or a person
|
|
tag, in which case you wouldn't see any notes from people with that
|
|
tag.</p>

Updates: Implement StoreRemoteMedia for v3 and port Embed
|
|
</title><description><![CDATA[
|
|
|
|
<p>GNU social comes with two plugins that add relevant media functionality.
|
|
Not talking neither about ImageEncoder nor VideoEncoder this time, but rather about StoreRemoteMedia and Embed.</p>
|
|
|
|
<p><a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/plugins/StoreRemoteMedia">StoreRemoteMedia</a>
|
|
fetches remote files when they are <code>Linked</code> to in a note. I.e., when the major mime type isn't <code>text</code>. It triggers thumbnail generation.</p>
|
|
|
|
<p><a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/src/branch/v3/plugins/Embed">Embed</a>
|
|
attempts to generate a page preview from open graph and oembed. I.e., acts when the major mime type is <code>text</code>.</p>
|
|
|
|
<p>We've changed so much with GNU social v3 that, regarding SRM there was no possible port, just a complete rewrite. Both plugins became smaller and easier to understand while promoting the same functionality with more stability.</p>

Updates: Improve the Attachments system
|
|
</title><description><![CDATA[
|
|
|
|
<p>With the milestone <a href="https://www.gnusocial.rocks/v3/milestone-port-media-handling-from-v2.html">Port Media system from
|
|
v2</a> we had ported the existing
|
|
attachment system. The fact is that this system wasn't good enough.</p>
|
|
|
|
<p>It's always important to start with the original code as that allows us
|
|
to review past decisions and understand all the corner cases previously
|
|
considered.</p>
|
|
|
|
<p>Sadly, what motivated us to re-design the attachment system were the
|
|
non-considered corner cases. In particular:</p>
|
|
|
|
<ul>
|
|
<li>Remove <code>title</code> from attachment, as it's part of the relation between attachment and note.</li>
|
|
<li>Remove <code>actor</code> from attachment, many actors may publish the same attachment.</li>
|
|
<li>Remove <code>is_local</code> from attachment, as it's part of the relation between attachment and note.</li>
|
|
<li>Remove <code>remote_url</code> from attachment, different urls can return the same attachment.</li>
|
|
<li>Attachment now has a reference counter </li>
|
|
<li>Add entity GSActorToAttachment</li>
|
|
<li>Add entity GSActorToRemoteURL</li>
|
|
<li>Add entity RemoteURL</li>
|
|
<li>Add entity RemoteURLToNote</li>
|
|
<li>Add entity RemoteURLToAttachment</li>
|
|
<li>AttachmentToNote now has a title attribute</li>
|
|
</ul>
|
|
|
|
<p>Key commits:</p>
|
|
|
|
<ul>
|
|
<li><a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/commit/32ad5dbd74ebb369c4b3ed688e1fb78464fabe49">32ad5dbd74 - [ENTITY] Split Attachment in various new entities</a></li>
|
|
<li><a href="https://code.undefinedhackers.net/GNUsocial/gnu-social/commit/c381e58d3307e7dd07abeb9cf5b3998e34f5bd48">c381e58d33 - [ENTITY] Refactor RemoteURL entities to Link</a></li>
|
|
</ul>
|
|
|
|
<p>The structural changes and how it compares to v2 is detailed in our
|
|
<a href="http://agile.gnusocial.rocks/doku.php?id=attachment">wiki</a>.</p>
|
|
|
|
<p>Some relevant observations:</p>
|
|
|
|
<ul>
|
|
<li><code>Link</code> is now part of GNU social Data Representation terms. It represents
|
|
any remote URL being shared in a note.</li>
|
|
<li>There's only one fixed directory for GSFiles.</li>
|
|
</ul>
