I'm working on moving a number of Wiki's to V1.9 and have hit a problem with the kWBreadCrumbs extension, which is complaining about both wfStrencode & wfQuery functions, I've tried the various suggestions about replacing wfStrencode with addQuotes() but I'm rather out of my depth. The rest of the extension works with 1.9 (I've dot it running without the kwBreadCrumbsNoCache function, any help would be appreciated, as I'm out of my depth here, I've added the function code to this email. If I can get it working I'll add it back into the extensions list if this is felt appropriate.
Change:
wfStrencode($blah) to $db->strencode($blah) (or better $db->addQuotes($blah); note this includes the outer quotes)
wfQuery($blah, DB_WRITE, $fname); to $db->query($blah, $fname);
(or better use the various query-builder functions, which will tend to be safer due to applying propr quoting always, and may be more portable for not-quite-standard constructs).
These long-, long-, long-obsolete functions have been removed because they are unreliable -- it's hard to know which database object they will be sent to, and that's generally icky.
You get a Database object from wfGetDB(DB_MASTER) or wfGetDB(DB_SLAVE). Writes must go to the master *only*. Many read operations can be taken from a slave, which will spread load away from your primary server in a load-balancing replication setup. (On a single server they will both return the same connection.)
