A recent server upgrade seems to have broken our installation of
LibStats. It appears that the database abstraction layer it uses,
PEAR::DB, is not working correctly. Once instantiated, it's supposed to
have methods like getOne() and getAll() that execute a SQL query and
retrieve the results; but keeps complaining that these are undefined.
I'm pretty sure this has something to do with the fact that the upgrade
-- to Ubuntu 16.04.1 LTS -- installed PHP 7, up from 5.6. According to
the PEAR web site, PEAR::DB is supposed to be compatible with PHP 7
despite being ancient and crufty, but it's not working.
Anyone have any insight on how to get PEAR::DB to play nice in its new
environment? Because the other option would be going in and rewriting
all the database queries to use a more modern database abstraction
layer. Probably PDO. That's certainly doable, but it'd be quite a
pretty fair chunk of work, and in the meantime our reference and access
services staff can't log their stats normally.
