[Sqlrelay-discussion] LD_PRELOAD problem

[D. V. <as...@gm...>]

Hello,

I've got a problem with the mysql drop-in replacement library on Debian 4.0

Basically this:
vm-99:~# ldd `which mysql` | grep sql
        libmysqlclient.so.15 => /usr/lib/libmysqlclient.so.15 (0xb7d0a000)
vm-99:~# LD_PRELOAD=/usr/lib/libmysql50sqlrelay-0.37.1.so.1 ldd `which
mysql` | grep sql
        /usr/lib/libmysql50sqlrelay-0.37.1.so.1 (0xb7eea000)
        libmysqlclient.so.15 => /usr/lib/libmysqlclient.so.15 (0xb7c9a000)
        libsqlrclient-0.37.1.so.1 =>
/usr/lib/libsqlrclient-0.37.1.so.1 (0xb79ca000)

It seems regardless I specify the mysql replacement library, the mysql
client library (which I've used for testing) was somehow "forced" to
use the original one.

It isn't working:

vm-99:~# LD_PRELOAD=/usr/lib/libmysql50sqlrelay-0.37.1.so.1 mysql
--host=localhost --port=9000 --user=root -p
Enter password:
Welcome to the MySQL monitor.  Commands end with ; or \g.
Your MySQL connection id is 0
Server version: 5.0.0

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql> show tables;
ERROR:
Failed to get a cursor id.
 A network error may have ocurred.
mysql>

Do anyone have an idea why does it happen?
