Hi Jaroslaw.
I'm checking that.
In my nunit tests here I'm not getting this problem.
We had this problem some time ago, but we already fixed it. But may there is
some case which is still getting problems.
In the Open method, near its end, and before the call to ProcessServerVersion
there is a line:
ServerVersion = Connector.ServerVersion;
Could you check what is the value of ServerVersion when this code executes?
Also, a little bit above, is where we set the Connector.ServerVersion. Could
you also check what value is being set?
Thanks in advance.
Regards,
Francisco Figueiredo Jr.

Re: [Mono-list] Re: Npgsql doesn't work anymore
I've made some tests. My new diff is attached (I've added two WriteLine's,
one of them never was never executed).
The output is:
ZZZ ServerVersion: False
_serverVersion is null
-
Hope it helps.
BTW. I've tried to add "MaxPoolSize=0" to the CS but it just caused the
connection to hang.

Sorry, obviously I forgot to add the diff.

This is the output I get with the latest cvs code... AAA ServerVersion: PostgreSQL 7.3.4 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5) True ZZZ ServerVersion: PostgreSQL 7.3.4 on i686-pc-linux-gnu, compiled by GCC gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5) True If you aren't seeing the AAA output, it's because the connector is already initialized, but it shouldn't!! Could you add the following lines in your test app? NpgsqlEventLog.Level = LogLevel.Debug; NpgsqlEventLog.LogName = "NpgsqlTests.LogFile"; This will create a file NpgsqlTests.LogFile with logging which could help track the problem. Thanks in advance. The output is: ZZZ ServerVersion: False _serverVersion is null - Hope it helps. BTW. I've tried to add "MaxPoolSize=0" to the CS but it just caused the connection to hang. Yeap, it has to be at least 1 :) I will add a check for that. -- Regards, Francisco Figueiredo Jr. Membro Fundador do Projeto MonoBrasil - MonoBrasil Project Founder Member http://monobrasil.softwarelivre.org - "Science without religion is lame; religion without science is blind." ~ Albert Einstein ___ Mono-list maillist - [EMAIL PROTECTED] http://lists.ximian.com/mailman/listinfo/mono-list
Re: [Mono-list] Re: Npgsql doesn't work anymore
OK. It was my fault. I didn't notice the first AAA message (I ran the tests through nunit) My problem was related to invalid hostname in the connection string. I should have used localhost instead of DNS name. After I changed it - it worked.
