upgrade webpy from 0.62 to 0.70 due to python 3.13 removal of cgi module

[detheridge02]

I've setup a new server to host ASM3 version 50.

When accessing the site Apache is throwing an error :

Thanks for raising this. We were using webpy 0.62 with our own patches, however it still has a dependency on the cgi module - which has been removed in Python 3.13.

I've upgraded to webpy 0.70 on our master branch and reapplied our patches. In terms of getting it running on your setup, you will need to either pull the latest code from git or downgrade Python/Debian to Bookworm.

@bobintetley Will there be a new .deb build?
Thanks for the prompt fix!

[detheridge02]

I see you've rolled back webpy to 0.62 for Multipart.
I'm not sure if it's related but the 0.70 code caused a further error (after installing python3-multipart) :

File "/usr/lib/sheltermanager3/asm3/i18n.py", line 10, in <module>
ModuleNotFoundError: No module named 'asm3.__version__' 

[bobintetley]

Yes, it's just temporary while I work on it. The issue is that the multipart package in Debian 12 and Ubuntu is ancient and doesn't have the functions needed by webpy, so I'm going to have to bundle it alongside the updated webpy.

The version file is constructed as part of the build/make process, which I guess you haven't run? You could copy the one from your old build if needed, or create it:

#!/usr/bin/env python3
VERSION = "51u [Tue  2 Sep 11:14:45 BST 2025]"
BUILD = "0902111445"

[bobintetley]

It seems webpy 0.70 is fundamentally broken with multipart posts, even when using the correct version of multipart. I can see where the devs are working on it, and I'll look into it as well. But for now, this is not going to be a quick fix.

I would suggest downgrading to Debian 12 until it's resolved and using v50 as is.

[bobintetley]

Ok, I think I have everything working on 0.70 now. I've merged multipart and 0.70 together for our bundle since there are fixes we've submitted to web.py years ago now that still haven't been merged upstream. If you're at the stage where you can build, it should now work with Debian 13.

I appreciate you raising this now, because we'll be moving to Debian 13 for some of our hosted servers in the next few months.

[detheridge02]

No problem. I've updated and it's all working well thanks. If you need anyone to run some tests give me a shout, I'm great at breaking things ;-)
Is there anywhere I could drop a feature request? A simple(ish) one to allow upload extensions to be changed. The shelter I work for has a lot of older managers that prefer doc/docx
