    I just moved generator>History to the more standardly named generator > history and also put its content into a more standard form, with a link to generator. The cache bug is here, but that's nothing new. This is: the link to generator shows up as unfilled. An unwary editor could even create a new generator page, overwriting the current one, without realising it! (Although given where they find the link, an experienced editor would know better.)

    I’m afraid that the cache bug fooled you. The page generator was not created. All the log entries for that page over the relevant time period say:

    Page `generator` not found
    

    meaning that there was no page with that name in the database. However, there does appear to have been a redirect with that name and so there was a page in the cache and that’s what you were seeing. Looking further back in the logs, there appears to have been a page called generator created in April 2012. Maybe that became generator>History (there’s no record of page name changes) and the cache copy never got cleared. Anyway, however it happened, there is no record of anyone saving a page named generator until I just did it.

    So I’m not sure what you actually did there, but what you think you did isn’t what the server thinks you did!

    Did you just copy material from the history of generator > history to generator or what?

    I see that we also have separator. I should have done more work untangling this.

    What I did was the following. I clicked on the generator link in your post. That took me to a page. Then I clicked on the generator > history link where I got the grey link to generator. Overcome by curiosity, I clicked on it and it took me to the new link. I felt sure it would complain or it would just add a revision to the list1. It didn’t. A new page was created. I then felt a bit stupid as I was sure I’d deleted all your work so tried to recover the original data from the database. It wasn’t there. That’s when I went searching in the logs and discovered that it had never been there. Since I still had the generator page in a tab, I figured I would recreate it by copying across what was at the previous revision of generator > history and making the necessary edits. But once I’d copied it over, I couldn’t find any differences (not that there might not have been any - it was getting late by this time).

    So I don’t know what happened at your end. If you want me to look further in the logs, I can do so.


    1. Partly irrelevant since I didn’t know this at the time, but I’ve just experimented on page one (doriath) and found that if you deliberately recreate an existing page then it just acts as if you edited it. The difference being that you are presented with a blank edit box. Whilst it would be better if new redirected to edit on existing pages, this does mean that recreated pages are recoverable by rollbacks so nothing is lost.

    It looks likely that generator was combined into separator sometime around the new year, and the cache bug simply lasted for a rather long time. I am now combining everything into separator.

    Actually, the history is more complicated than that. On November 8, Urs wrote something brief at separator, then Tim combined generator into that four hours later, then Urs wrote over Tim's changes a couple hours more later. (I can only guess that Urs had the page open for editing for several hours, so that the 30-minute warning time warned neither Tim nor Urs.)

    OK, separator now has all of the missing material. We have generator > history and generator > history II; generator should redirect to separator but gets the cache bug instead.
