For a while now, e-mail notification and everything triggered by non-NULL values of watchlist.wl_notificationtimestamp (unseen edits bolded in Special:Watchlist and marked with green "changed since your last visit" markers in the history) have not worked on Meta, a wiki that does have these things enabled (testwiki doesn't, although it probably should for testing).
Steps to reproduce:
- Add a page on Meta to your watchlist
- Enable the "e-mail me when pages on my watchlist are changed" preference and make sure you have a confirmed e-mail address
- Log out and edit the page anonymously
- Log back in and go straight to Special:Watchlist without visiting the edited page first
- Observe that your anonymous edit shows up, but the page isn't bolded (it should be)
- Click the relevant (hist) link, which takes you to the history view for the edited page
- Observe that your anonymous edit doesn't have a green "changed since your last visit" marker (it should)
Strangely, all of this works on my local install (running HEAD).
