Watchlist like the one on Wikipedia

[Martin Scharrer]

Logged-in users should have an entry on the meta-nav-bar which allows them to add or remove the current wiki page to a personal watch list. Then there should be a page (e.g. /watchlist) which displays all the watched wiki pages with name, last change date and author, as well as links to diffs and a remove button, etc. See ​http://en.wikipedia.org/wiki/Special:Watchlist for reference.

Adding tickets to the watch list would be an additional feature.

My thought about the implementation:

• Create table watchlist with user,id,realm. Id is the wiki name or ticket number and the realm is either wiki or ticket (IEnvironmentSetupParticipant).
• Implement an INavigationContributor to add a meta-nav link for all wiki or ticket pages. If the wiki or ticket isn't already watched it should be an add button, otherwise an remove button.
• If the current user has a (non-empty) watchlist the main-nav should have a watchlist button to point to /watchlist.
• The watchlist is displayed using an IRequestHandler and a SQL query like: select name,author,MAX(time) from wiki where name in (select id from watchlist where user = 'martin' and realm = 'wiki') group by name order by time;.
• An custom Genshi template can be used for this (ITemplateProvider).

I might implement it by myself if I find the time.
