Description

I got this on October 25th 2006:

Warning: mysql error: Can't connect to local MySQL server through socket
'/var/lib/mysql/mysql.sock' (2) in query:

select count(*) from `tiki_banners` where `wed` = ? and `hourFrom`<=?
and `hourTo`>=? and
( `useDates` = ?) and (`fromDate`<=? and `toDate`>=? or
(`useDates` = ?) ) and
`impressions`<`maxImpressions` and `zone`=?

in lib/tikidblib.php on line 134


How could we show a more meaningful error message?



mysql tables sometimes crash.

When they do, the error message is cryptic, at best.

An average Tiki admin won't know what the problem is and could think it's Tiki's fault.


A graceful error message would inform the admin that:

"There are problems with the following tables: ". Please repair (link to how to repair)

Especially the tiki_sessions, which shuts down the site completely...

Some others are not so bad. Just a path disclosure.

Warning: mysql error: Can't open file: 'tiki_images.MYI' (errno: 145)  in query: select count(*) from `tiki_images` where `galleryId`=?  in lib/tikidblib.php on line  134


Another error to watch for:

Image
Unable to connect to the database !
User droit_tiki has already more than 'max_user_connections' active connections

Maybe Tiki admin email should be in db/local.php? So the system could send email alerts when DB can't connect.

Solution

Please upgrade to a recent version of tiki.
If the problem persists, please add a new tracker item.

Keywords

The following is a list of keywords that should serve as hubs for navigation within the Tiki development and should correspond to documentation keywords.

Each feature in Tiki has a wiki page which regroups all the bugs, requests for enhancements, etc. It is somewhat a form of wiki-based project management. You can also express your interest in a feature by adding it to your profile. You can also try out the Dynamic filter.
