Description Dereckson 2013-04-29 12:37:17 UTC
Some thumbnails aren't updated on a PNG update.

File:

Comment 1 Nemo 2013-04-29 13:12:48 UTC
Purging a couple dozens times didn't help. I don't know if it's related, but yesterday (I think) there was reuploaded SVG whose original didn't get purged; I had to manually purge it and the HTTP request took 12 s to have an answer, presumably while the cache servers retrieved the original.

Are there more files, or just that one?

Do you refer to the 800px version, and/or others?

And last but not least, what exactly is the difference that I can spot to compare with my eyes?
Comment 3 Andre Klapper 2013-04-29 14:43:40 UTC
By the way, required data can be seen here: bug 46976 comment 8.
Needs two wget commands that show different file sizes, preferably.
Comment 4 Dereckson 2013-04-29 15:40:59 UTC
800px are ok, 250px and 300px aren't.

Old version: https://upload.wikimedia.org/wikipedia/commons/archive/4/44/20130429085637!Christian_distribution.png

New version: https://upload.wikimedia.org/wikipedia/commons/4/44/Christian_distribution.png

You can spot the difference in the the legend at the bottom.

workaround does not scale. I think there are more instances.

This particular file is fixed but there seem to be more:

* https://commons.wikimedia.org/wiki/File:River_Rak_going_underground.ogv

$ wget --no-check-certificate -S https://upload.wikimedia.org/wikipedia/commons/3/37/River_Rak_going_underground.ogv

always gives the old file! (Can be seen by   "Content-Length: 104609673"
and   "Last-Modified: Tue, 23 Apr 2013 16:00:17 GMT" )

The real fix is fixing bug 43449.

That's not about thumbnail purging, but about the actual file. :)
Hence separate bug reports are better, as it's a different problem.
I've created bug 48004 for it.
