CommentStreams ist ein Kommentarsystem für Wikis. Benutzer*innen können Kommentare unter den Inhalt einer Wikiseite posten. The comments are displayed with the user's username, linked to their user page if it exists, the creation and last modification dates of the comment, and an optional user avatar. Kommentare können nur vom Kommentarautor bearbeitet oder gelöscht werden. Comments are added in streams which include a title and a head comment that can be replied to by other comments.

CommentStreams does not depend upon any other extensions, but it provides several additional features if some other extensions are installed:

  • If Echo is installed, web and email notifications are sent to users who have enabled them when comments are added on pages the user is watching or replies are posted to comments authored by the user.
  • If Semantic MediaWiki is installed, optional, user-configurable properties to set an avatar and display name for a user as well as special properties that can be queried on each comment to provide the comment title, a link to the page to which the comment refers, and a link to the head comment if the comment is a reply.

CommentStreams stores comments on pages in the CommentStreams namespace. These pages are given a randomly-generated string of characters as the name. Users cannot edit or delete these pages directly. A database table stores the comment title and IDs of the page to which the comment refers and the page containing the head comment if the comment is a reply.

Installation

  • Die Erweiterung herunterladen und die Datei(en) in ein Verzeichnis namens CommentStreams im Ordner extensions/ ablegen.
    Entwickler und Code-Beitragende sollten stattdessen die Erweiterung von Git installieren, mit:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/CommentStreams
  • Folgenden Code am Ende deiner LocalSettings.php -Datei einfügen: 
    wfLoadExtension( 'CommentStreams' );
  • Führe das Aktualisierungsskript aus, welches automatisch die notwendigen Datenbanktabellen erstellt, die diese Erweiterung braucht.
  • Konfiguriere nach Bedarf.
  • Because CommentStreams uses DISPLAYTITLE, you will need to set the following variables:
$wgAllowDisplayTitle = true;
$wgRestrictDisplayTitle = false;
  • Yes Erledigt – Navigiere zu Special:Version in deinem Wiki, um zu überprüfen, ob die Erweiterung erfolgreich installiert wurde.
If you are enabling CommentStreams with Semantic MediaWiki, you must load CommentStreams before enabling Semantic MediaWiki.

Upgrading to Version 7.0

Two major changes were added in Version 7.0 that require special care upon upgrading:

  • change to the database schema
  • change to the way comment block ids are stored

The change to the database schema requires that you first upgrade to version 6.3 if you are running an earlier version and then upgrade to version 7.0. If you want to upgrade to a version after version 7.0, upgrade to version 7.0 first.

With respect to comment block ids, in versions prior to 7.0 the cst_id column of the cs_comment_data table stored the MD5 hash of the comment block name prepended by 'csc_' except for the default comment block, which is designated by 'cs-comments' in the cst_id column. This made it extremely difficult to maintain comment blocks. If a comment block was renamed in wikitext, there was not an easy way to identify which rows needed to get adjusted.

Version 7.0 replaces the value in the comment id column with null for the default comment block and with the name of the comment block (unhashed) for named comment blocks. It no longer uses the comment block name as an id for the element in the DOM. Version 7.0 includes three maintenance scripts that can be used to update the database and to move comments between comment blocks:

  • extensions/CommentStreams/maintenance/MigrateToAbstractSchema.php is run on upgrade by maintenance/update.php to null out the comment id column for rows that previously were set to 'cs-comments' (the default comment block) and to change the database schema. You should not need to run this script directly, as it is run once by maintenance/update.php.
  • extensions/CommentStreams/maintenance/listCommentBlocks.php lists all of the comment blocks either across the entire wiki or, with the 'pages' option, sorted by the page they appear on.
  • extensions/CommentStreams/maintenance/migrateCommentBlock.php takes the unhashed name of a comment block and either replaces cst_id with the unhashed name for all rows that currently hold 'csc_' followed by the hashed name - or - takes both a from name and a to name to rename any comment block.
  • extensions/CommentStreams/maintenance/migrateDefaultCommentBlock.php takes an (unhashed) comment block name and migrates all comments in the default comment block to the new comment block name.

To upgrade from previous versions of CommentStreams to version 7.0 or later,

  • If the version is older than 6.3, upgrade to version 6.3 and run maintenance/update.php.
  • Upgrade to version 7.0 and run maintenance/update.php.
  • If your wiki contains named comment blocks, use the extensions/CommentStreams/maintenance/migrateCommentBlocks.php script to rename them in the database. You can use the extensions/CommentStreams/maintenance/listCommentBlocks.php script to see which comment blocks exist in the database currently.

Konfiguration

Konfigurationsflag Standardwert Beschreibung
$wgCommentStreamsNamespaceIndex 844 The index of the CommentStreams namespace. This defines the constants NS_COMMENTSTREAMS and NS_COMMENTSTREAMS_TALK and assigns the value NS_COMMENTSTREAMS + 1 to NS_COMMENTSTREAMS_TALK. NS_COMMENTSTREAMS is configured to be a content namespace, and it is configured to be searchable. If Semantic MediaWiki is installed, it is also configured to allow semantic properties. See extension default namespaces.
$wgCommentStreamsAllowedNamespaces null An array of indices of namespaces that will display comments by default. To display comments in namespaces not listed in $wgCommentStreamsAllowedNamespaces, use the ‎<comment-streams /> tag function as described below. If the value ot $wgCommentStreamsAllowedNamespaces is null, the value of $wgContentNamespaces will be used. To allow comments on pages with the presence of the ‎<comment-streams /> tag function only, set $wgCommentStreamsAllowedNamespaces to -1.
$wgCommentStreamsNewestStreamsOnTop true If this is true, comments streams will be displayed with the newest comment stream on top. If it is false, the newest comment stream will be on the bottom. Comment streams are sorted chronologically by creation date of the head comment.
$wgCommentStreamsInitiallyCollapsedNamespaces [] An array of indices of namespaces in which the comment streams will be displayed collapsed (i.e. only the head comment showing) when the page is initially rendered if comment streams are enabled in that namespace. For other namespaces with comment streams enabled, the comment streams will be displayed expanded when the page is initially rendered. After the page is rendered, comment streams can be toggled between being expanded and collapsed by clicking on the EXPAND/COLLAPSE toggle button in the top right of the comment stream.
$wgCommentStreamsUserRealNamePropertyName null If Semantic MediaWiki is installed, this variable is given a Text value, and a property named with that value exists on a user's user page, then the value of that property will be used as the display name for that user on any comments authored by them. If this variable is not set or the property does not have a value, then if DISPLAYTITLE has been used to set the displaytitle page property of the user page, the displaytitle value will be used, Otherwise, if the user's real name is set in the database, the value from the database will be used. Otherwise, the user's username will be used.
$wgCommentStreamsUserAvatarPropertyName null If Semantic MediaWiki is installed and SocialProfile is not installed, this variable is given a Page or Text value, and a property named with that value exists on a user's user page, then if the value points to a File: page for an image (e.g. File:MyAvatar.png), this image will be used as an avatar for the user beside their name on any comment authored by them. If these conditions are not met, no avatar will be displayed unless the SocialProfile extension is installed. By default, the avatar will be sized to 48 pixels in height, but this can be overridden by changing the width and height properties of .cs-avatar in CSS.
$wgCommentStreamsShowLabels true If true, show labels beside the Add and Reply buttons. If false, do not display the labels.
$wgCommentStreamsModeratorFastDelete false If true, allows users with csdelete right to delete a comment and all of its replies in one action rather than having to individually delete all of the replies first.
$wgCommentStreamsEnableVoting false If true, allows logged in users to vote thumbs up, thumbs down, or neither on top level comments.
$wgCommentStreamsEnableSearch true If true, disables comments from appearing in search results and titles from appearing in search auto-complete.
$wgCommentStreamsSuppressLogsFromRCs true If true, comment-related logs will not be added to Special:RecentChanges.

Semantische MediaWiki-Unterstützung

If Semantic MediaWiki is installed, CommentStreams defines the following properties on each comment page, which can be used to query for comments:

Eigenschaftsname Typ Beschreibung
Comment on Page The page that this comment refers to.
Reply to Page The page containing the head comment that this comment is a reply to if this comment is a reply.
Comment title of Text The comment title of this comment if this comment is a head comment.
Comment up votes Number The number of up votes on the comment (if $wgCommentStreamsEnableVoting is true).
Comment down votes Number The number of down votes on the comment (if $wgCommentStreamsEnableVoting is true).
Comment vote diff Number The difference between the number of up votes and the number of down votes (if $wgCommentStreamsEnableVoting is true).

CommentStreams namespace

You can use the MediaWiki search box to search for comments. In the search result page, the page that the comment appears on, rather than the comment page in the CommentStreams namespace, appears in the search results. While it is possible to visit comment pages directly in the CommentStreams namespace, for example if they are listed in Special:RecentChanges, this is not encouraged. Editing, deleting, and moving comment pages by visiting them in the CommentStreams namespace is disabled. Instead editing and deleting comments is done from the content page on which the comment appears.

Aktivieren und Deaktivieren von Kommentaren auf einer Seite

CommentStreams also offers two tag functions, ‎<comment-streams /> and ‎<no-comment-streams />.

‎<comment-streams /> enables CommentStreams on a page even if it is in a namespace in which comments are disabled. Optionally, an id for the comment block may be provided: <comment-streams id="some-unique-id"/>.

‎<no-comment-streams /> disables CommentStreams on a page even if it is in a namespace in which comments are enabled.

If both of these tag functions exist on a page, the last one parsed will win.

Multiple comment blocks on a page

If you want to place more than one comment block on a page, you can use <comment-streams id="some-unique-id"/> with a different unique id in each tag. If a comment block with an id (also referred to as a named comment block) appears on the page, the default comment block (the comment block with no id) will not appear unless ‎<comment-streams /> appears in the wikitext of the page.

Platzierung der Kommentare

The default comment block (the comment block with no id) will always be placed at the bottom of the page below the categories. (Note that this is a change from prior to version 7.0 where the default comment block would appear on the page where it appeared in the wikitext. The earlier behavior caused complications in namespaces where comments were not enabled by default.)

Named comment blocks (those with a unique id) will appear on the page where they appear in the wikitext. If you have only one comment block on a page that you want to place specifically, you can also use <comment-streams id="{{FULLPAGENAME}}"/>

Initially collapsed CommentStreams

CommentStreams also offers a tag function, ‎<comment-streams-initially-collapsed />, which makes comments appear initially in a collapsed state (only the comment header with the comment title, author, dates, and buttons showing) on a page. This tag function has no effect if comments are disabled on the page.

Comment right

If no groups are assigned the cs-comment right, then all users who have the edit right are allowed to post and reply to comments. The cs-comment right can be assigned, for example, to the group commenters by setting 

$wgGroupPermissions['commenters']['cs-comment'] = true;

If you use the LockDown extension, you might want to use this to prevent access to the Special page that shows all comments: 

$wgSpecialPageLockdown['CommentStreamsAllComments'] = [ 'cs-comment' ];

Anonyme Kommentare

It is possible to enable anonymous comments by setting 

$wgGroupPermissions['*']['cs-comment'] = true;

Anonymous commenters are warned that their IP address will be recorded if they post or reply to a comment and that they will not be able to edit or delete their comments after they are submitted. While these comments show anonymous as the author on the page where the comment appears, the author's IP address does appear in the comment log and comment page history.

Echo-Unterstützung

For a user to receive Echo notifications by web or email, the Echo extension must be installed and echo notifications must be enabled for that user. To enable CommentStreams Echo notifications by default for all users on a wiki, the following configuration should be used: 

$wgDefaultUserOptions["echo-subscriptions-email-commentstreams-notification-category"] = true; // enable email notifications
$wgDefaultUserOptions["echo-subscriptions-web-commentstreams-notification-category"] = true; // enable web notifications

Users may edit their notification settings by visiting the page Special:Preferences#mw-prefsection-echo.

Notifications will be sent to a user when another user posts a new comment or a reply on a page the first user is watching. Notifications will also be sent to a user when another user posts a reply to a comment the first user is watching. A user can watch a comment by clicking on the star on the comments title bar. Clicking on the star again will remove the comment from the user's comment watchlist. When a users posts a new comment, it will automatically be added to the user's comment watchlist.

If it is taking a long time to create or reply to a comment with Echo enabled, you can have the Echo event creations done on the job queue (see Erweiterung:Echo ), by setting the following: 

$wgEchoUseJobQueue = true;

Kommentarmoderation

A group (csmoderators) and two new rights (cs-moderator-edit and cs-moderator-delete) exist to support comment moderation. By default, members of csmoderators have the csdelete right (they may delete any comment) but they do not have the cs-moderator-edit right (they may not edit any comment). Those rights may be assigned to other groups or changed. In addition, the $wgCommentStreamsModeratorFastDelete configuration variable makes it easy for moderators to quickly delete entire comment threads. For example: 

$wgGroupPermissions['csmoderator']['cs-moderator-edit'] = true;
$wgCommentStreamsModeratorFastDelete = true;

As an aid in comment moderation, the special page "Special:AllComments" lists all comments in reverse chronological order of when they were last edited.

Avatar

If the SocialProfile extension is installed, avatars set for users will be displayed beside the comments and replies they author. If the Social Profile extension is not installed but the Semantic MediaWiki extension is installed, the $wgCommentStreamsUserAvatarPropertyName configuration variable can be used to specify avatars.

Version 4.3.1
  • Sanitized comment wikitext before passing back to the browser to avoid future XSS vulnerability.
Version 4.3
  • Added ‎<comment-streams />
Version 4.2
  • Fixed Special:AllComments for comments beginning with a '+'

  • changed DB_SLAVE to DB_REPLICA, requiring MediaWiki 1.30+
Version 4.1
  • Removed foreign key from comment data table as it was causing issues deleting pages with comments on them for some database versions.
