[isf-wifidog] MySQL support - shouldn't we skip it?

I'm OK, as long as you don't use highly specific non-SQL99 / SQL2003  
commands. Can anybody confirm that the new PHP PDO supports BLOB  
encapsulation for Postgresql ? And I don't mean BYTEA fields, I'm  
referring to OID-based BLOBs. We'd have to modify some SQL generation  
logic for using PDO's prepared statements, but that should be trivial  
in most cases, althought since its critical and it has to be done  
carefully ...

I'm all for not taking care of MySQL too much, but with MySQL 5.0  
plenty of things have changed ... it will be more and more trivial to  
support it I guess. For 1.0, let's forget it. But moving to PHP PDO  
is always a good thing, if only for preventing SQL Injection with  
prepared statements. I haven't analyzed all our code , but just  
escaped strings might not be enough... ie. $user_id="0; DELETE FROM  
users" ....  "SELECT * FROM users WHERE user_id = {$user_id};"    So,  
we might be vulnerable where we use integers fields. PDO's prepared  
statement take care of this by escaping semi-colons, adding single  
quotes on integer fields etc...
