Webalizer stats missing or way too low every now and then

by Erik Zachte

Gabriel Wicke wrote: "Webalizer can't analyze logs out of order, so it just discards them when they arrive the next day." Server outages may be a partial explanation, yet low figures occur on different dates for different wikipedias and some were not effected at all. I'm not yet quite convinced that figures near but unequal zero on 5 days in April for en: (April 11-13 and 28-29) can be explained this way. Certainly outages did not occur 5 times around 00.15 AM. http://en.wikipedia.org/stats/usage_200404.html#DAYSTATS Erik Zachte

old revisions on test.wikipedia.org

by Gabriel Wicke

There's a weird phenomenon on test.wikipedia.org with 1427 old revisions only holding the text 'abc'. If it was just a flawed manual mysql query done around may 4 then we could be sure it's not a bug- if not we'd have to do a fair bit of investigation. This problem didn't appear in any other wiki running the cvs code, but to know is better than to guess in this case. Would be a serious bug/security problem otherwise. -- Gabriel Wicke

Webalizer stats missing or way too low every now and then

by Erik Zachte

Gaps or unrealistic low figures exist on many wikipedias on different days e.g. en: April 11-14 and 27-29 pl: April 19, May 5 de: May 1-2 ja: May 4 etc See for example file:///D:/Wikipedia/@Test/Csv/Webalizer/EN/usage_200404.html#DAYSTATS Of course other days may be affected partially and show reasonable figures which are yet in fact too low. e.g. de: May 3 is suspect For the international stats I assume extremely low figures are in fact faulty and treat them as missing, except when a known outage occurred, like in December 2003. However this is less than ideal. Is there some explanation for irratical webalizer stats and possibly a cure? Erik Zachte

images and the category system

by fabiform

People have just started [[Wikipedia:List of images]] (see http://en.wikipedia.org/wiki/Wikipedia:List_of_images/Animals for an example). It's a sorted list/index of images displayed in a simple gallery (using the markup: [[Image:Image Name.gif|thumb|100px|left|Short Description]]). It seems to me that this would be better organised using the category system. Would it be possible to create image categories which displayed their contents in a gallery like this, rather than as a list of links to image description pages? I don't know how we'd deal with the captions, other than making them be the file name, which might not be that useful... but creating a category system by hand like these pages are doing does seem labour-intensive.

Caching stuff

by Brion Vibber

I've checked in today two updates for caching certain types of data, which creates two new tables: querycache and objectcache. querycache is used for QueryPage derivatives which are considered "expensive": Wantedpages and its evil friends. For each special page, it stores up to 1000 page title<->numerical value tuples, to be returned sorted either forward or backwards. Storing a largeish number in a table instead of the first 50 in pre-rendered HTML in a hidden page solves a couple of problems: the pages can be checked for existence etc at view time (a common complaint on Wantedpages), you can page through a reasonable quantity if the first page's worth has been dealt with, and the hidden pages will no longer show up in contributions lists and other unexpected places. The interface to QueryPage has changed a bit to accomodate the requirement to save the data in an ordered fashion, though pages that don't need to cache (such as Newpages, which is indexed reasonably well) can still pull extra info. objectcache is in theory usable as a generic memcached workalike that's stored in the database. This seems to defeat the purpose of memcached... ;) but for the limited case of caching the all-messages bundle with $wgUseDatabaseMessages it's almost as fast on a lightly loaded system at least, and is a fair chunk faster than pulling every message individually. Results of quick n' dirty benchmark, take with grain of salt: DBM MEM OBJ median X n n n 1432 1.0 Y Y n 1550 1.08 Y n Y 1566 1.09 <- Y n n 1815 1.27 DBM = $wgUseDatabaseMessages MEM = $wgUseMemcached OBJ = using objectcache median = median milliseconds to render & load a short page in MonoBook on my powerbook (no PHP, file or squid cache), on a run of 50 hits, concurrency level 2. X = time compared to baseline, pulling from raw language files I've changed the interface of MessageCache to take the memcached interface object rather than a true/false check whether to use the global object. If not using memcached, the objectcache table will be automatically used. -- brion vibber (brion @ pobox.com)

I agree, last time, when Brion moved db from Suda to Curly, db was down during 2 hours, time to copy 60GB through a 100Mb network. Shaihulud
