Description Carl Austin Bennett 2006-12-31 20:33:43 UTC
Presumably, `hitcounter` is an SQL memory table which temporarily pagenumbers as
pages are viewed; this is supposed to be periodically written back to the main
database. The number of entries amassed before doing so is $wgHitcounterUpdateFreq.

With the MW 1.9-svn software (Dec 29 version, installed with memcached and
eAccelerator), I'm seeing entries do indeed find their way into the `hitcounter`
table (in memory) but then never get written back to the main `page` table. They
accumulate until $wgHitcounterUpdateFreq records are created in memory, then
they disappear entirely.

End result is that, for example, if "this page has been viewed 230234 times":
come back a few days later and it's still at 230234.

Configuring the wiki to write the page counter to the main database on every
pageview does make the problem goes away - but with a penalty in speed.
Comment 1 Brion Vibber 2007-01-01 00:03:48 UTC

hc_n FROM `hitcounter` GROUP BY hc_id
SQL ERROR (ignored): You have an error in your SQL syntax; check the manual that
corresponds to your MySQL server version for the right syntax to use near
'ASSELECT hc_id,COUNT(*) AS hc_n FROM `hitcounter` GROUP BY hc_id' at line 1

Fixed in r18704.
