Tech:Cache bug on DE

From Wikitravel Shared
Jump to: navigation, search

What happens[edit]

The cache isn't always being cleared when after someone edits. I noticed this when I was editing de:Mobile, and again after editing the de:Wikitravel:Kandidaten für das Reiseziel des Monats.

After several edits I realized the cache was not being cleared and had to manually purge the cache for the updated version of the page to display.

When it happens[edit]

Randomly, but it began today (Tuesday, January 23, 2007)

I already noticed it on 21 January 2007 editing this here [1]. I thought it is a problem with my browser's cache. For me it happens every time I edit a page. --Flip666 21:50, 23 January 2007 (EST)

What should happen[edit]

The cache should be cleared after the page is edited and the current/updated form of the page should be displayed. However, with this problem the opposite is happening and when I edit a page and the page is reloaded the edits are not displayed until the user purges the cache manually.

How to fix it[edit]

If I knew I wouldn't work in a kitchen. -- Andrew Haggard (Sapphire) 20:55, 23 January 2007 (EST)

OK, so, a few days ago I set the "cache epoch" -- the minimum time for the cache to report how old a page was -- as 21 Jan. We'd changed the titles to show "Reiseführer für ...", and this would let browsers and bots know that they should get the new version. However, I mistyped the date (it's in a funky format), and it ended up being a meaningless number that MediaWiki treated as "infinitely far in the future". So, caching wasn't working.
I've fixed the number so it should work correctly. You may need to manually reload some pages for a while, but it should correct itself soon. Let me know if there are further problems. --Evan 01:49, 24 January 2007 (EST)
Thank you. -- Andrew Haggard (Sapphire) 12:53, 24 January 2007 (EST)
