Greetings,

I think the following may be a bug in mod_python. I can't seem to find a
bug database or tracker for mod_python?

When subscripted access is used to access variable 'SCRIPT_FILENAME' in
the request.subprocess_env table/mapping, the code hangs.

The following snippet illustrates the problem.

# -=-=-=-=-=-=

def postreadrequesthandler(request):
request.add_common_vars()
value = request.subprocess_env['SCRIPT_FILENAME']    # This hangs
# value = request.subprocess_env.get('SCRIPT_FILENAME')# This works
return apache.OK

# -=-=-=-=-=-=

The strange thing is that the .get() access works fine: only the
subscript hangs?

The environment is

Apache:     2.0.59
ModPython:  3.2.10
Python:     2.4
OS:         Windows Server 2003

If anyone is wondering about a use-case, I don't actually have one. I
was just iterating over the contents of the request.subprocess_env using
a for loop (code below), and found that the code hung when accessing
'SCRIPT_FILENAME', and not for any other variable.

# -=-=-=
d = {}
for sek in request.subprocess_env.keys():
d[sek] = request.subprocess_env[sek]
# -=-=-=

Regards,

Alan.

No time to investigate right now. I'll take a look tonight.
