[Sqlrelay-discussion] Testing sqlrelay's drop-in replacement libraries on Debian Wheezy

[Petros M. <ern...@ya...>]

I' ve tested sqlrelay's drop-in replacement libraries for MySQL and
PostgreSQL on Debian Wheezy (x86_64).

The drop-in for MySQL does not seem to work. It just hangs when trying
to connect with the mysql client program. It asks for password and after
entering it, it freezes without ever giving back a mysql prompt. Maybe
this is related to the fact that Debian Wheezy comes with mysql 5.5, but
sqlrelay provides libraries up to 5.1? If this is not relevant, I would
be glad to do any tests needed to narrow down the possible causes of the
problem.

The drop-in replacement library for PostgreSQL works when using the psql
client program.
However, it is not usable if trying to connect with psycopg2, the most
popular library to interface with postgres from python. In particular,
psycopg2 checks for the protocol version of the connection and if it is
not 3, it exits. Maybe sqlrelay's implementation of postgres api does
not support protocol version requests. Dave, if that is the case, would
it be easy to include support for this type of requests in a following
release of sqlrelay?
