[Sqlrelay-discussion] Sqlrelay 0.39.4 + dropin mysql library + PHP 5.1.6 + MySQL 5.0.22

[Jani O. <jan...@pr...>]

Hi,

Subject is the problem.

If I set the LD_PRELOAD cli mysql client
can connect and works nicely.

But with PHP neither pdo_mysql or mysql
works. It just hangs when connecting.

Strace says it is trying to connect the
right socket but it just cannot get anything from there.

Any ideas?

The system is CentOS.

Strace output:
connect(3, {sa_family=AF_FILE, path="/tmp/sqlrelay.sock"}, 110) = 0
setsockopt(3, SOL_IP, IP_TOS, [8], 4)   = -1 EOPNOTSUPP (Operation not 
supported)
setsockopt(3, SOL_SOCKET, SO_KEEPALIVE, [1], 4) = 0
