Installation

  • The database user must have been granted the "REFERENCES" right for the database. How you check this depends on how you set up the database in the first place. For example, if you used a control panel application, then that interface should provide a way to check and change the privileges of the database user ($wgDBuser in LocalSettings.php ).
  • Download and move the extracted Echo folder to your extensions/ directory.
    Developers and code contributors should install the extension from Git instead, using:cd extensions/
    git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/Echo
  • Add the following code at the bottom of your LocalSettings.php file: 
    wfLoadExtension( 'Echo' );
  • Run the update script which will automatically create the necessary database tables that this extension needs.
  • If necessary configure at your convenience
  • Yes Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

To allow daily or weekly summary notifications to be delivered by mail (for users that choose that in preferences), the following script inside the Echo extension directory needs to be run on a daily basis, which can be scheduled in a cron job: 

maintenance/processEchoEmailBatch.php

Configuration

It is possible to use conditional user options to set different notification preferences for new users, without affecting existing users.

See Special:DisplayNotificationsConfiguration for local details.

Parameters

$wgEchoNewMsgAlert true Whether or not to enable a new talk page message alert for logged in users.
$wgNotifyTypeAvailabilityByCategory 
[
	// Otherwise, a user->user email could trigger an additional redundant notification email.
	'emailuser' => [
		'web' => true,
		'email' => false,
	],
	'mention-failure' => [
		'web' => true,
		'email' => false,
	],
	'mention-success' => [
		'web' => true,
		'email' => false,
	],
]
Define which notify types are available for each notification category. If any notify types are omitted, it defaults to $wgDefaultNotifyTypeAvailability.
$wgEchoNotifiers 
[
	'web' => [ 'EchoNotifier', 'notifyWithNotification' ],
	'email' => [ 'EchoNotifier', 'notifyWithEmail' ],
]
Definitions of the different types of notification delivery that are possible. Each definition consists of a class name and a function name. See also EchoNotificationController class.
$wgEchoAgentBlacklist [] List of usernames which will not trigger notifications
$wgEchoOnWikiBlacklist Echo-blacklist Page location of community maintained blacklist within NS_MEDIAWIKI containing one username per line which will not trigger notifications. Set to null to disable.
$wgEchoPerUserWhitelistFormat %s/Echo-whitelist An sprintf format of the location of the per-user notification agent whitelist within the NS_USER namespace. %s will be replaced with the users name. The whitelists must contain one username per line which will always trigger notifications regardless of their existence in the blacklists. Set to null to disable.
$wgEchoCrossWikiNotifications false Whether to enable the cross-wiki notifications feature. To enable this feature you need to:
  • have CentralAuth for a global user system (T243412)
  • have $wgMainStash and $wgMainWANCache shared between wikis
  • configure $wgEchoSharedTrackingDB
$wgEchoUseCrossWikiBetaFeature false Feature flag for the cross-wiki notifications beta feature

If this is true, the cross-wiki notifications preference will appear in the BetaFeatures section. If this is false, it'll appear in the Notifications section instead.

This does not control whether cross-wiki notifications are enabled by default. For that, use $wgDefaultUserOptions['echo-cross-wiki-notifications'] = true;

$wgEchoNotificationCategories See extension.json Define the categories that notifications can belong to. Categories can be assigned the following parameters. All parameters are optional:
  • priority - controls the order in which notifications are displayed in preferences and batch emails. Priority ranges from 1 to 10. If the priority is not specified, it defaults to 10, which is the lowest.
  • no-dismiss - disables the dismissability of notifications in the category. It can either be set to an array of output formats (see $wgEchoNotifiers) or an array containing 'all'.
  • usergroups - specifies an array of usergroups eligible to receive the notifications in the category. If no usergroups parameter is specified, all groups are eligible.

If a notifications type doesn't have a category parameter, it is automatically assigned to the other category which is lowest priority and has no preferences or dismissibility.

$wgEchoNotificationIcons See extension.json Defines icons, which are 30x30 images. This is passed to BeforeCreateEchoEvent so extensions can define their own icons with the same structure. It is recommended that extensions prefix their icon key. An example is myextension-name. This will help avoid namespace conflicts.

You can use either a path or a url, but not both. The value of 'path' is relative to $wgExtensionAssetsPath.

The value of 'url' should be a URL.

You should customize the site icon URL, which is: $wgEchoNotificationIcons['site']['url']

$wgEchoNotifications See extension.json Define the event types for echo. Event definitions are in the form of 'event-name' => [ ... ].
  • category - defines the category the event belongs to. Defaults to 'other'.
  • group - defaults to 'neutral'.
  • bundle - define which output formats are available for bundling.
  • presentation-model - define which class is used to render notification messages and links for notification panels, special page and emails. It must extend EchoEventPresentationModel.
$wgEchoConfig See extension.json Configuration for EventLogging. Individual schemas can be disabled.
$wgEchoPerUserBlacklist null Boolean that enabled Per User Blacklist.


User preferences

Preference settings (defaults defined in extension.json)
Preference Default Comment
$wgDefaultUserOptions['echo-email-frequency'] 0 How often to send emails, by default:
  • 0 - send emails for each notification as they come in (default)
  • -1 - do not send emails
  • 1 - each day
  • 7 - each 7 days
  • ...
$wgDefaultUserOptions['echo-email-format'] Depends on $wgAllowHTMLEmail Default user preference for whether to use HTML or text email. Either html or plain-text.
$wgDefaultUserOptions["echo-subscriptions-email-{$category}"] false for most categories; depends Default user preference for whether to notify via email for a particular category
$wgDefaultUserOptions["echo-subscriptions-web-{$category}"] true for most categories; depends Default user preference for whether to notify via web for a particular category


Architecture

See the architecture section of the feature page .

Usage

Notification negative list / positive list

There are occasionally specific users, typically bots, which perform maintenance tasks that should not generate notifications. To handle these cases, users can be globally blacklisted from the LocalSettings.php file (or InitialiseSettings.php in the case of WMF wikis): 

$wgEchoAgentBlacklist = [ 'SampleBot', 'SampleUser' ];

There is also an on-wiki blacklist that can be maintained by the wiki's community. The location of the global on-wiki blacklist defaults to MediaWiki:Echo-blacklist. Individual users can override the blacklist by creating a whitelist. The whitelist location defaults to Special:MyPage/Echo-whitelist. All on-wiki lists expect to receive one case-specific username per line with no special markup or prefixes. For example: 

SampleBot
SampleUser

"Mention" option

One of the notification types that this extension allows is: "Notify me when someone links to my user page." It might not be obvious to some users, but this particular notification only works when the person linking to another user's page also signs (~~~~) the post.

After installation of the extension, a new tab "Notifications" is created in a user's Special:Preferences page. Under the section "Notify me about these events", in front of the "Mention" option, the hoverbox states: "Notify me when someone links to my user page." If an administrator feels, that the requirement for signing the post isn't obvious in this help text, it can be modified by changing the text in the Wiki's MediaWiki:Echo-pref-tooltip-mention page.

Terminology

  • notification - Any individual notice that is delivered by Echo
  • message - A notification about activity in a Flow discussion
  • alert - Any notification other than a message
