nLab > nLab Technical Matters: The cache bug is dead ... I hope

    I’ve been experimenting with installing a local version of instiki to try to find a reliable set of steps to convince Jacques that the cache bug exists. After discovering that it didn’t exist on my local version, I started comparing it with a live installation (actually mathsnotes) and found that one key module was at a newer version in my local installation when compared with the live installation. I updated that module and - hey presto! - the cache bug disappeared.

    I’ve updated that module on the nLab as well and the steps that I’d found that reliably showed the cache bug no longer do so. I’ve deleted the entire cache from the nLab (not the personal webs). So with a bit of luck the cache bug should be well and truly squashed.

    Of course, I feel Murphy’s law lurking around the corner so I’ll not believe that it has gone until about a year’s gone by with no-one reporting it … but I’m hopeful.

    Huzzah! That’s truly wonderful news… perhaps people here should try doing the usual things they did which led the cache bug to rear its ugly head. But many thousands of thanks in advance, Andrew.

    Great. Incidently I once had a computer with a faulty keyboard which when I tried to type book it produced bok, when I typed good I got god, and for dog …. strangely it sometimes came out as doog!

    There is the old announcement: The King is dead, long live the King! so perhaps Urs’s comment on the Lab Down thread is of the same ilk!

    Andrew,

    could you maybe check, it seems to me I just ran into the cache bug again: go to Comparison lemma and then try to edit it. That will take you to the HomePage, signaling the fact that the entry had meanwhile been renamed to comparison lemma, but the old caching is still there. It seems to me.

    Oh … botheration.

    So, not completely dead then.

    I did a bit more digging, and have made a conjecture about the cause of the cache bug. Jacques still can’t reproduce it, although I get pretty consistent results between the nLab, my course wiki (mathsnotes), and a test installation on my local machine.

    So, with Jacques’ blessing, I’ve made a small modification to the Instiki code underlying the nLab which ought to clonk the cache bug firmly on the head. We’ll see …

    I don't know if the cache bug has come back from the dead or thisis anew bug, but I no loger get ntification of recent posting to n-cafe or nforum as I used to. I am ablew to click on the name n-category cafe or nforum
    and can then scroll through a bunch of stuff, but it was much better to have a lsitn fo what's new.

    Jim, you weren’t using Google Reader, were you? (I was, but switched over to The Old Reader after Google announced they were pulling the plug on their own Reader.)

    Getting off-topic, but how do you like The Old Reader, Todd? I was also left high and dry by the death of Google Reader; so far I’ve been using Feedly, which is okay but not ideal.

    The math seems to render better for me on TOR than it ever did with GR, so that’s a definite plus. Overall, I think this gives it an edge over GR; there is some minor annoyance where, if you click on an older post, the posts after that one temporarily lose their markings as unread (so that I feel obligated to read in reverse chronological order). But maybe there’s an easy fix; I’m not too good with stuff like that.

    Jim,

    That’s definitely not the cache bug, since that was related to the nLab itself and neither the forum nor the café. I’m not sure what’s going wrong with the forum. If you go to the “Account” tab and click on “Notifications” in the menu on the left-hand side then you can see what things you should get notified about. Are any of those checked?
