Flyspray

Mmh, there is the Notifications tab where you can add a user as listener to a task.

An implementation of this feature require implementation for both dokuwiki and HTML/CKeditor syntax.

How do you want avoid misusage of that feature (spamming users for instance)
–> use of an existing permissions?

The autocomplete feature could use the same as the current autocompleter used in Flyspay + a javascript listener that reacts whenever the typing starts with a '@' or

\s+@

(regular expression) is typed (like in github.com)

If a user is mentioned in a task or comment, should that user be added to the notification list if he is not yet there?

That would mean:

• For dokuwiki description/comment must be parsed when saving serverside, not only on output.
• For HTML/CKeditor the HTMLpurifier configuration must be used or extended (avail since FS 1.0-rc4)

Before implementing, the Flyspray notification system should be reviewed. So probably not before FS1.1

If a user is mentioned in a task or comment, should that user be added to the notification list if he is not yet there?

hm when i compare it to other systems, then a mention would not add him to the notification list. i think it is the decision of the user to go to the list. or when the user want this user explicit in this list. i would only send him one notification when he is added to a task or a comment.
when the task/comment will be edit he dont get a e-mail.

something pseudo code like this:

if($aclAllowMentions) {
foreach(preg_match($userFromRegex == REGEX \s+@, $_POST['xyz'])  {
   $hasMention = (bool)$db->select('SELECT ID from ticket/comment where ID = $ticketID AND content LIKE "%@.$userFromRegex%"');
 
  if(!$hasMention) {
     notify::send('you go mentionted by user xyz in ticket/coment xyz (content preview)';
  }
}
}

the dokuwiki/HTML/CKeditor can we do in a second step.

(if you want i can implement it)

At least added now a mention plugin for Flyspray dokuwiki syntax that turns @username into a link to user profile. ( https://github.com/Flyspray/flyspray/tree/mentionlink )

Maybe a starting point.

Having a mention notification system requires tracking it in db tables, so whenever a comment or task is edited again, only new first time mentioned users of that task/comment are notified, right?

<table name="mention_user_task">
  <field name="user_id" type="I"><NOTNULL/></field>
  <field name="task_id" type="I"><NOTNULL/></field>
  <field name="created" type="T or D"></field>
  <field name="notified" type="T or D"></field>
  <index name="mention_user_task">
    <UNIQUE/>
    <col>user_id</col>
    <col>task_id</col>
  </index>
</table>
<table name="mention_user_comment">
  <field name="user_id" type="I"><NOTNULL/></field>
  <field name="comment_id" type="I"><NOTNULL/></field>
  <field name="created" type="T or D"></field>
  <field name="notified" type="T or D"></field>
  <index name="mention_user_comment">
    <UNIQUE/>
    <col>user_id</col>
    <col>comment_id</col>
  </index>
</table>

Maybe the datetime fields are not needed, just thought of a user had disabled mention notifications, then enables mention notification again, then a summary of time between last received mentions and now could be received. (meanwhile you were mentioned 1234 times in task and comments since you disabled notifications .. lol, or a list of tasks)

One more thing: How to handle (or prevent?) username retaken by other user after a user deleted himself or was deleted by admin?

Example

What solutions are possible?

@username

[@userid]

@username

Should the generated dokuwiki mention link expose info if the mentioned user is enabled/locked?

Should a hover with mouse show info of the mentioned user like real name, avatar, roles, .. ?

Some more thoughts about dokuwiki mention links:

How to limit/avoid a sql squery for each detected mention pattern for our dokuwiki mention link plugin?

Example: Lets say task list limit is 250 items, each task has a few mentions in their description or one funny guy creates a task with 1000 pseudo mentions…

dokuwiki mention plugin separates between normal mention in paragraph, table, list - but ignores within code snippets and the replacement

@username

with an actual html link is done on output, not cached.

Disable mention link plugin for task list preview (mouse hover)
Or do not generate hidden task description abstract for the task list view and replace it with an optional ajax request when hovering the task summary?
