Subject: [Freeswitch-users] Problem importing modules in mod_python
To: freeswitch-users@lists.freeswitch.org (freeswitch-users@lists.freeswitch.org)
Message-ID: <195670.44941.qm@web50805.mail.re2.yahoo.com (195670.44941.qm@web50805.mail.re2.yahoo.com)>

In the latter versions of mod_python, I'm unable to import standard python modules such as time and MySQLdb.?
For example, the following script works fine in version 1.0.1:

??? ??? import time
??? ??? import os
??? ??? from freeswitch import *
??? ??? def handler(session, args):
??? ??? ??? session.answer()
??? ??? ??? session.execute("sleep", "2000")
??? ??? ??? session.streamFile("/usr/local/freeswitch/prompts/01Welcome.wav")
??? ??? ??? return(session)

But in freeswitch-1.0.latest.tar.gz, and svn versions 10556-10558, I get the following error:

??? ??? 2008-11-30 21:13:09 [ERR] mod_python.c:129 eval_some_python() Error reloading module
??? ??? Traceback (most recent call last):
??????? File "/usr/lib/python2.4/site-packages/scripts/test.py", line 1, in ?
??? ??? import time
??? ??? ImportError: /usr/lib/python2.4/lib-dynload/timemodule.so: undefined symbol: PyExc_ValueError

Thanks for your help!

I have run into the same problem and put some documentation on the wiki:

http://wiki.freeswitch.org/wiki/Mod_python#ImportError:_.2F...2Fdatetime.so:_undefined_symbol:_PyExc_IOError

I think something changed in freeswitch in the way it is loading modules, or at least the way it is loading mod_python. This behavior appeared all of the sudden in recent freeswitch versions.

we no longer use global name space in our shared objects which seems to have a side effect on modules who in turn try to load it's own shared objects because they too inherit the non-global namespace param.

you can either add an attribute to the modues.conf to ask it to load with global name space

<load module="mod_foo" global="true"/>

or you can edit the code to request global loading every time.

by adding the param SMODF_GLOBAL_SYMBOLS to the SWITCH_MODULE_DEFINITION macro
(See mod_cepstral at the top)

Try changing the module definition to use global symbols the same way we did in mod_lua, see if that resolves the issue.
