Summary: connection problem with postgresql driver 8.03.0100 to postgresql 8.3.0

Initial Comment:
I compiled postgres odbc driver version 8.03.0100, but when I try to connect
to a 8.3.0 postgres database, then there connection/authentication problems
happen:

isql FIS MyUser MyPassword -v
[28000][unixODBC]Communication error during authentication;
Error while reading from the socket.
[ISQL]ERROR: Could not SQLConnect
dbuser@dbhost:~> isql FIS MyDatabase MyDatabase -v
+---------------------------------------+
| Connected! |
| |
| sql-statement |
| help [tablename] |
| quit |
| |
+---------------------------------------+
SQL>

I can only connect to the database by a chance of 1/10. Also when I get
connected, then when I try entering a SQL statement, I get error messages
about not being connected anymore.

and below the postgres log from the tries:


LOG: connection authorized: user=MyUser database=MyDatabase
LOG: unexpected EOF on client connection
LOG: disconnection: session time: 0:00:00.002 user=MyUser

LOG: statement: select pg_client_encoding()
ERROR: synt x error at or near " at character 1
LOG: could not send data to client: Broken pipe
LOG: unexpected EOF on client connection

This is the part of the configuration from my odbc.ini:
[FIS]
Description = PostgreSQL DB
Driver = PostgreSQL
commlog = yes
Database = MyDatabase
Host = localhost
Server = localhost
ServerName = pdtest106.pdtest.intern
Username = MyUser
Password = MyPassword
Port = 5430
Protocol = 6.4
ReadOnly = No
RowVersioning = No
ShowSystemTables = No
ShowOidColumn = No
FakeOidIndex = No
ConnSettings =

Actually, I have no idea, what the protocol version number means. The
version 6.4 was the one I found most of the time in the net. I also tried to
set it to 8.3, and 8.3.0, but with no difference. Any pointer to an
explanation would be great.

when I exchange the odbc driver file, with an older one, odbc drvier version
8.1.2, then I do not have connection/login problems at all.

Message:
I just retried to compile against postgresql 8.3.1, but
with the same result. Note, for the test I did not used
your patch.

Forgot to mention, I compiled with and
without --disable-unicode --disable-openssl
but both versions show the same results.

Thanks for the patch, I just tested. It did not apply
cleanly:
/usr/local/src/psqlodbc-08.03.0100 # patch -p0
< ../psqlodbc.patch
patching file ./socket.c
Hunk #1 succeeded at 347 (offset -6 lines).
Hunk #2 FAILED at 519.
Hunk #3 FAILED at 529.
Hunk #4 succeeded at 811 (offset -6 lines).
Hunk #5 succeeded at 868 (offset -6 lines).
Hunk #6 succeeded at 947 (offset -6 lines).
2 out of 6 hunks FAILED -- saving rejects to
file ./socket.c.rej

However, after taking a look into the source and the patch
file, I changed the section to look like this:

#ifdef USE_SSL
/*
* The stuff for SSL.
*/
/* included in */
#define SSL_ERROR_NONE 0
#define SSL_ERROR_SSL 1
#define SSL_ERROR_WANT_READ 2
#define SSL_ERROR_WANT_WRITE 3
#define SSL_ERROR_WANT_X509_LOOKUP 4
#define SSL_ERROR_SYSCALL 5 // look at error
stack/return value/errno
#define SSL_ERROR_ZERO_RETURN 6
#define SSL_ERROR_WANT_CONNECT 7
#define SSL_ERROR_WANT_ACCEPT 8
// */

However, the patch did not helped.
I still get these error messages:

isql MyDatabase -v
[28000][unixODBC]Communication error during
authentication;
Error while reading from the socket.
[ISQL]ERROR: Could not SQLConnect


The mylog_root21305.log is from above message.


isql MyDatabase -v
[S1000][unixODBC]The database does not exist on the server
or user authentication failed.
[ISQL]ERROR: Could not SQLConnect

The mylog_root21305.log is from above message.

Message:
Could you attach the Mylog output ?
You will be able to take the log (/tmp/mylog_xxxx.log) by adding the line
Debug = 1
to your odbc.ini.
