Note: The documentation of the extension has only partially been maintained since March 2006, but most of its features have been added to MediaWiki version REL1_6 in 2006. See Manual:Configuration settings#Email notification (Enotif) settings et al. Please take note that all Foundation wikis have Email notification enabled since May 14, 2011 - check your personal preferences to opt-in if you like to receive notification mails for changes on your user page (see also the help page).

This page and related bugzilla bugs will be updated in the next couple of days to reflect the current state. --Wikinaut 11:35, 14 May 2011 (UTC)

Email Notification (ENotif) v3.x/CVS REL1_4, REL1_5 ► Documentation ▪ Screenshots ▪ Installation ▪ To-Do list ▪ FAQ ▪ Bugs ▪ Versions ▪ Your feedback ▪ all pages at once

 

• E-mail notification (ENotif) - a program notifies a user by e-mail of page changes or page creation (listed as enhancement bugzilla 454) and
• E-mail address confirmation (EConfirm) - a program that confirms the stored e-mail address by e-mailing a link (enhancement bugzilla 866)

For the impatient: quick how-to

Operating System	GNU/Linux
Distribution	Debian Jessie
Mediawiki version	1.20.3
E-mail server	Postfix, installed on the same server as mediawiki

1. Installing PHP PEAR:

sudo aptitude update; sudo aptitude install php-pear

2. Install PEAR packages:

sudo pear install mail net_smtp

3. Edit:

sudo cp /srv/www/wiki/LocalSettings.php /srv/www/wiki/LocalSettings.php.bak
sudo vim /srv/www/wiki/LocalSettings.php

And add below lines:

# Email
$wgEnableEmail = true;
$wgEnableUserEmail = true;
$wgEmergencyContact = "admin@example.com";
$wgPasswordSender = "app_robot@www-1.local.example.com";
$wgEnotifUserTalk = true;
$wgEnotifWatchlist = true;
$wgEmailAuthentication = true;
$wgSMTP = array(
 'host'     => "127.0.0.1",
 'IDHost'   => "www-1.dev.local.jamgo.org",
 'port'     => 25,
 'auth'     => false,
);

NOTE : the value " IDHost " must match the hostname (run command "hostname")

4. Edit the postfix config file:

sudo cp /etc/postfix/main.cf /etc/postfix/main.cf.bak
sudo vim /etc/postfix/main.cf

And make sure the lines are as follows:

myhostname = www-1.dev.local.jamgo.org
mydestination = www-1.dev.local.jamgo.org

5. Restart services:

sudo /etc/init.d/postfix restart
sudo /etc/init.d/apache restart

6. Setting the User "watcher " to receive emails

6.1. Sign in mediawiki

6.2 . Go to "preferences/user profile"

6.3 . Make sure that you have valid email address and check all the options on "Email options" box

6.4 . Edit "page" and watch it.

7. Log in with user "editor" and edit "page". Once you are done save the changes.

Expected behaviour: www-1.dev.local.jamgo.org host should send an e-mail to e-mail address of user "watcher". You can check it live with:

sudo tail -F /var/log/mail.log

If it's not working, just in case:

1. Log out both users 2. Login user "watcher" and unwatch and watch again page "page" 3. Repeat step 7

EConfirm: E-mail address confirmation

• When a user adds or changes the e-mail address during account creation or on the user preferences form, the wiki sends a confirmation link to this address. The address remains marked as unconfirmed until the user follows the link. All enhanced mail functions, currently a) e-mail to user and b) e-mail notification, do only send mails to confirmed addresses, and nothing to unconfirmed addresses.

• E-mail address confirmation can be used and configured independently from ENotif: enabled or disabled with the switch $wgEmailAuthentication. If the switch is set to false, messages regarding (un)confirmed addresses are suppressed, and all e-mail functions do work (if e-mails as such are enabled on this wiki) as in standard MediaWiki.

• When using ENotif, you should always enable EConfirm. In that case, the wiki mails only to confirmed addresses.

• E-Mail addresses of bureaucrats, developers or sysops become confirmed as they are entered, i.e. without the confirmation cycle. This behaviour can be configured (enabled as described or disabled) with switch $wgEmailConfirmationRequiredForAll.

• The status (unconfirmed or date/time of confirmation) is always shown beneath the address on the user preferences page

• E-mail addresses are currently not checked for compliance with RFC-2822 when they are stored in the database. This is issue of bugzilla:959.

• If a user changes their e-mail address to another, non-empty address, the wiki automatically sends a link for confirmation.

Some of the enhancement bugs are marked as (OPEN); this means, that I will implement these enhancements in one my next versions.

"What can I expect and how does it work ?"

Basics

A single e-mail is sent to the watching user x

• if the WikiSysop has globally enabled this feature in the DefaultSettings.php or LocalSettings.php
• and if the user has stored an email address in the user preferences
• and if the user has enabled the personal enotif options in the user preferences

on the event that

• someone else changes a watched page listed in user x's watch list or
• someone else changes the user or user_talk page of user x or
• someone else creates a new page (if enabled by WikiSysop; a user option is shown in the preferences page)

No further mails are sent to you until you re-visit the watched page - or a difference view against it.

Update marker

All users can enjoy a side-effect of enotif - regardless whether they have enabled or disabled their personal enotif options:

• A garish updated marker  updated (since my last visit)  indicates new content on watch-listed pages since the last visit (of user x). The updated marker appears on the a) watchlist page, b) recent changes page close to the bold-titled page names of watched pages, and c) page history. Note: your own changes never trigger notification mails or "updated" markers, so you only get e-mails about somebody else's changes that you haven't seen.

The marker is so garish and big to attract your attention and because it directly links to show you the difference between current and last seen version of that page, see below. Before complaining: you can switch it off by un-checking the corresponding option in your preferences.

1:  updated (since my last visit) 

Markers indicate all watched pages with unseen changes.

Markers are also direct links to the (same) difference view between the current revision of that page and the(my) last-visited revision.

They link to http://server/testwiki/index.php?title=User:Test&diff=0&oldid=1956 in the example.

2: (last seen) : a direct link to Difference between this revision and the last seen revision (lsr)

These links are also active for older-than lsr revisions (e.g. you can quickly compare any arbitrary revision with the version, you saw last)

Only watched pages having unseen changes bear active (last seen) links; in the example you see some black inactive (last seen) links, because these pages are not watched pages. They cannot show unseen changes, because only watched pages offer information about last seen revision, which determines unseen changes of any watching the user.

3:   (last seen)   :

The(my) last visited revision of that page

4: [4] :

Number of users watching that page

See further screenshots on the versions page.

Features

• The ENotif patch was developed for small- to medium-scale MediaWiki implementations. Personalised e-mails (with recipient's name; times expressed in local time of the recipients) for every watching user. [The program flow will change in future versions to provide bulk notification e-mails, depending on parameters, to save processing time and bandwidth.]

• The sub-feature notification on user_talk page (UTP) changes could be enabled even for the largest WikiPedia, because the number of UTP changes is surprisingly low - according to Brion Vibber. About 800 alien UTP changes (changes by others than yourself) per day have been counted in August 2004, which would result in the same (relatively low) number of enotifs sent to the UTP owners.

• All features are configurable (enable/disable) in module DefaultSettings.php respectively LocalSettings.php for the WikiSysop, who can separately allow or disallow notifications for
  1. changes of pages in all name spaces (AO/UO) and/or
  2. changes of user and user_talk pages (AO/UO)
  3. creation of new pages (AO/SO/UO)

user preferences with an authenticated e-mail address and the new page notification option

• Implements and solves

Bug 1572 Add diff link to "You have new messages" (OK)

Bug 1876 Show "You have new messages on your user or user_talk page" -- i.e. both pages are notified (OK)

(AO) admin option:

allows to disable or fine-tune these extensions globally

(SO) special user option:

for bureaucrats, developers and sysops only

(UO) user option:

if the admin option enables the feature globally, a user option in user preferences is shown and allows the users to opt-in or opt-out to this feature at their discretion.

• The subject line and text of the notification message are pages in the MediaWiki:namespace and can therefore be changed live by Sysops. You can use several named $variables such as $PAGEEDITOR, see example below.

• The notification message contains a direkt link to the difference view (last seen) between the current page version and the last one the watching user has seen i.e. the page version just before the page change notification was sent. Remark: the (last seen) link is valid forever, because page revision identifiers are now sticky (permanent), they survive delete/undelete cycles since REL1_5 (this is not the case in older MediaWiki versions).

• Your own page changes or creation of a page (if enabled) never trigger a notification mail sent to yourself.

• Minor edits may trigger notification e-mails sent out depending on your preferences (AO/UO).

• All UTP changes trigger a notification, no matter whether the changing editor declared the change as minor edit or not.

• Only one mail is sent on the first page change. Further mails are suppressed until you re-visit the changed page or until you reset all notification flags. A new button has been introduced for this purpose on the watchlist page.

• On the watchlist page, a new marker  updated (since my last visit)  indicates such watched pages for which a notification mail was sent, meaning that the page has new content since your last visit (AO/UO).

• The marker also appears on your recent changes page and on page history pages for the pages watched by you (already marked bold) and have new content since your last visit (AO/UO).

• Recent changes view and page(article) footers show number of watching users (AO/UO).

• You can add non-existent page names to your watch list and receive e-mail notification if someone creates a page with that name. The updated marker appears for the page until you actually visit it.

• Debuggers can activate server beeps on notification mails, this is disabled by default. (AO)

Prerequisites

You definitely need a working php mail() system on your server. I suggest you quickly check your current wiki installation before trying the E-mail notification patch. Try requesting a temporary password for your wiki user account by clicking the button mail me a temporary password on the wiki login screen. If, sooner or later, you receive an e-mail from your "old" wiki, everything looks fine and ready for the installation of ENotif.

ENotif/EConfirm has been developed to work smoothly with

• php mail()

  thus it is not using the PEAR:Mail() module; see /includes/UserMailer.php

  $wgSMTP = false;

and

• MySQL database server

  thus it is not checked to work with PostgreSQL

  $wgDBtype = "mysql";

  $wgSearchType = "MyISAM";

For further information such as

• how to configure the php mail()
• Why do I need to set up a sender address information ("FROM:")
• and how to configure MySQL

please consult /includes/DefaultSettings.php

If you want to use it together with PEAR:Mail and/or PostgreSQL

• please let me know.

Code security and general issues

The code was peer-reviewed several times and the version 2.00 was committed to CVS HEAD (version 1.5) in December 2004. However, since then, several persons have modified this and that in the CVS HEAD version, which could have led to a non-working version in CVS.

I always publish a complete diff on the accompanying ENotif bugzilla.

"It does not work": common pitfalls

• Avoid the most common pitfalls from the beginning and read carefully:

Be aware, that

1. your wiki e-mail system must be working as such - test it by mailing you a temporary password (this is independent from ENotif)

   see provisionally Bug 664 for problems with PHP mail() function and PHP SAFE MODE mode enabled.

2. you obviously need an e-mail address - check the address field in user preferences
3. e-mail address must be marked as confirmed (if EConfirm is mandatory on your wiki)
4. there are never notifications for your own changes. Change a page watched by A as other user B and check, whether an ENotif is sent to watching user A.
5. only one ENotif is sent for the first page change of a page you are watching or, when a new page is created (if this feature is enabled)
6. notification is automatically re-enabled when you visit the current version of the page or the difference view to the current version
7. you also can clear all notification flags at one click (button on your watchlist)
8. you need to update the text message cache, if you have customized test strings in a LanguageXX.php file

Inside ENotif and EConfirm

Download

Available versions (see also version history)
always see EnotifWiki file release download section on BerliOS Open Source server
For MediaWiki developers version (CVS HEAD REL1_5)	Enotif v.2.x simply checkout or update from MediaWiki CVS, as this is the version included in MediaWiki 1.5 be reminded, that this large documentation page you are visiting now describes merely the features of my ENotif/EConfirm v3.x, now called EnotifWiki 3.x with permission of the Wikimedia Foundation. The 3.x version is much more powerful than the 2x, as it adds for example notification for new pages and the difference-to-last-seen-version links and has lean code. special version EnotifWiki v3.x for CVS REL1_5 beta versions code of is available from a repository on BerliOS Open Source Server be aware, in what subdirectories the code installs and save your directories, if you need it. important: the tgz files comprise CVS markers and tags, so that you easily can make further updates from CVS upon my version. Usually, you can delete these files (further instructions to follow on a different place).
For MediaWiki version 1.4.6	code of EnotifWiki versions before 3.47 for MediaWiki versions before 1.5 is available from an archived repository on SourceForge This version uses e-mail authentication, a deprecated method that e-mails a temporary password. It doesn't touch the regular password not being touched by this) This method has significantly changed in the other (newer) versions of EnotifWiki, which are strongly recommended; the new method being the same and therefore fully compatible with MediaWiki 1.5 mechanisms.
For older MediaWiki versions	See my archive or contact me.

Installation

• see Extension:email notification/installation

Implementation details and flowcharts

• see Extension:email notification/algorithms

Release Notes

• see Extension:Email notification/release notes

Configuration

ENotif configuration: sysop settings in /includes/DefaultSettings.php

• in LocalSettings.php or DefaultSettings.php
• (coming soon)

Notification mail (text templates and variables therein)

• In languages/Language.php, amongst other new constants, there are two important text templates with $VARIABLES, which get substituted with values when the ENotif mails are composed. The text templates are shown here for the sake of completeness of the documentation, so that you know in advance, what you can change.

• Please consult /includes/UserMailer.php if you are curious to learn where the variables such as $PAGEEDITOR get their values from, but you usually don't have to study this file.

• If you encounter problems with the message cache - e.g. that your changes on LanguageXX.php are not effective and do not work - please consult the pages you get with this search on MetaWiki. It is standard MediaWiki procedure, that you need to run an update program in certain cases !

MediaWiki:email_notification_body

This is the text template for the body of the notification mails. It resides in file /languages/Language.php and can be adapted by yourself according to your needs. You can change the text before or after the installation of your EnotifWiki. However, when you changed the text in the file /languages/Language.php after the installation, then it might be necessary to run once the program

run /maintenance/php rebuildMessages.php --rebuild

as explained above. This might take a few seconds. A detailed explanation, why this might be necessary, can be found on here.

Alternatively, you can also change the text live on your wiki by editing the page [[MediaWiki:email_notification_body]], but such a change must be done for every wiki, if you run several wikis.

MediaWiki:email_notification_subject

The previous section explains how you can change this text (change file /language/Language.php and run a maintenance program, or edit page [[MediaWiki:email_notification_subject]]).

{{SITENAME}} page $PAGETITLE has been $CHANGEDORCREATED by $PAGEEDITOR

Notification mail (sample)

• The subject text comes from language/Language.php MediaWiki:email_notification_subject as described above
• The body text comes from languages/Language.php MediaWiki:email_notification_body as described above
• This comprehensive (and therefore heavy) example shows all possibilities. If you wish to shorten the mail, you need to edit the Language.php file(s) or to change the mentioned MediaWiki: pages in your live system.
