Summary:                    upgrade to 5.3.10,REV=2012.02.10 breaks installed
libraries
Description: 
After upgrade to CSWphp5 5.3.10,REV=2012.02.10  and CSWphp5-mysql 
5.3.10,REV=2012.02.10, Mantis no longer can reach the database (the
database is up and running just fine: I use command-line mysql client and
query mysql just fine).

I am investigating to find the configuration file that got smacked.

I'm setting up a clean PHP/MySQL (client) install in another zone.
Meanwhile, googling the error message found this interesting statement from
the official PHP5 documentation
(http://php.net/manual/en/migration51.databases.php):

Changes in MySQL support

In PHP 4, MySQL 3 support was built-in. With the release of PHP 5.0 there
were two MySQL extensions, named 'mysql' and 'mysqli', which were designed
to support MySQL < 4.1 and MySQL 4.1 and up, respectively. With the
introduction of PDO, which provides a very fast interface to all the
database APIs supported by PHP, the PDO_MYSQL driver can support any of the
current versions (MySQL 3, 4 or 5) in PHP code written for PDO, depending
on the MySQL library version used during compilation. The older MySQL
extensions remain in place for reasons of back compatibility, but are not
enabled by default.

the bit at the end about 'not enabled by default' caught my eye. I need to
check Mantis and see whether it uses PDO. I would think, not.

You asked what PHP I upgraded from. I previously used the previous CSW
release. 5.1 I believe.
