Don't know if this should concern us in preparation for 2.0b1 release, but the following came across c.l.py this morning.

FYI.

I am beginning development of a very large web application, and I would like to use Python (no, Zope is not an option). PyApache seems to be my best bet, but there is a MASSIVE problem with Python/PyApache that prevents it from being even marginally useful to me, and to most major software companies.

My product requires database access, and the database module that I use for connecting depends on a library called mxDateTime. This is a very robust library that is in use all over our system (it has never given us problems). Yet, when I use PyApache to connect to a database, I have major issues.

I have seen this same problem posted to this newsgroup and to the PyApache mailing list several times from over a year ago, and it appears to be unresolved. The essential problem is this: the second time a module is loaded, Python has cleaned up its dictionaries in its cleanup mechanism, and does not allow a re-init. With mxDateTime this gives an error:

"TypeError:  call of non-function (type None)"

Essentially, this is a major problem in either the Python internals, or in PyApache. After tracing the previous discussions on this issue, it appears that this is a Python problem. I am very serious when I say that this problem must be resolved before Python can be taken seriously for use in web applications, especially when Zope is not an option. I require the use of Apache's security features, and several other Apache extensions. If anyone knows how to resolve this issue, or can even point out a way that I can resolve this myself I would love to hear it.

This is the single stumbling block standing in the way of my company converting almost entirely to Python development, and I am hoping that python developers will take this bug and smash it quickly.

Thanks in advance, please cc: all responses to my email address at jal@faxnet.com.
