[cx-oracle-users] finding the module from a connection

[Mario F. <mf...@zo...>]

I'm writing a library making use of various dbapi2 modules.

one of the options to inizialize my library is from an open database
connection cx.

I don't know how to get the *module* from the connection object, but
with most other dbapi2 modules, I can at least retrieve the *name*
of the module by taking cx.__class__.__module__

for a cx_Oracle database connection I get the string '__builtin__'

any hints?

thanks in advance,
Mario Frasca

I found the problem...  to solve it I had to modify the sources, not
much, but still...  

http://docs.python.org/ext/dnt-type-methods.html states:
    char *tp_name; /* For printing, in format "<module>.<name>" */

but 
mario@loki:~/cx_Oracle-4.1$ grep tp_name Connection.c 
    "OracleConnection",       // tp_name

modifying it to "cx_Oracle.OracleConnection" solves the problem.

I filed a bug report on the sourceforge cx_Oracle project, hope that is
the correct place.

regards, thanks,

Mario Frasca

Yes, that is the correct place. And apparently you also discovered
that this is not a problem with cx_Oracle 4.2.... :-)
