unixODBC (again)

Hi,

Having seen that the driver I distribute doesn't work against 7.1 Beta
4, and not wanting to continue the split between the two versions,
I have tried to get the driver in the beta working with unixODBC, but
I have come against a couple of problems, one a show stopper.

First let me say that I want to stop the split between the version, If
I can just point people to your distribution, thats fine by me, but it
needs to work :-). I am not trying to get you to standardise on
unixODBC, just to provide the option.

Initially I had to link my system odbc.ini to a user odbc, because the
driver looks in the home account. This would be SO much better if there
was a build option to link with libodbcini.so, not saying it should be
the default, just that the option would be great.

After this, it still didn't find the entries, I fould the problem was
the code couldn't handle spaces in the ini file, so

[dsn]
Servername=fred

works, but

[dsn]
Servername = fred

doesn't. Not a major point, but again the ini lib would fix this.

Then having sorted this out, I get a core dump, that I have traced to
CC_lookup_pg_version, the code did

CC_lookup_pg_version(ConnectionClass *self)
{
HSTMT hstmt;
StatementClass *stmt;
RETCODE result;
char *szVersion = "0.0";
static char *func = "CC_lookup_pg_version";

Then later did a

sprintf( szVersion... );

This seems to be trying to write into, what the compiler is marking as
read only storage. A quick change to

CC_lookup_pg_version(ConnectionClass *self)
{
HSTMT hstmt;
StatementClass *stmt;
RETCODE result;
char szVersion[ 3 ];
static char *func = "CC_lookup_pg_version";

strcpy( szVersion, "0.0" );

Fixes the problem, and it connects. I will continue testing, with some
apps and see how it gets on
