oauth.py uses cgi.parse_qs which isn't available anymore

[Alberto Donato]

python-oauth uses cgi.parse_qs, which was deprecated in python3 (in favor of the urllib equivalent), and is no longer available in python 3.8.

Thanks Alberto. The library is not in a very nice shape, with no upstream development for more than 11 years and the python3 module being auto-generated with 2to3. Apparently 2to3 doesn't handle switching cgi.parse_qs to the urllib equivalent.

Currently python-oauth and python3-oauth have no reverse dependencies in the archive, at least in Focal and Groovy, so I wonder if we still want the package in the archive. There are probably reasons for which we do, given that you hit this bug and doko restored the python-oauth binary package in 1.0.1-6ubuntu1 mentioning in the changelog that it's still needed. The reasons are however not clear to me.

Can we consider dropping the package from the archive in Groovy?

It's needed for MAAS, Alberto hit this bug whilst looking to update MAAS to a Focal (core20) base.

FWIW, there's a pending request to remove python-oauth from the archives at #1118815.

Hi Adam,

Interesting. Given that Focal ships Python 3.8, how do you guys make python-oauth work?

Thanks!

[Alberto Donato (ack)]

@Paride @Sergio, we're getting rid of python-oauth uses in MAAS, so there's no blocker on our side for the focal RM.

[Alberto Donato (ack)]

(Sorry I meant groovy RM)

[José Pekkarinen (koalinux)]

the python maas cli hits this for dns-ha, the fix is quite straight
forward as now parse_qs comes from urllib.parse, instead of cgi,
changing the calls to use this package will fix it.

José.

Hi José, is the cli in question python-libmaas?

If so, this has been switched to oauthlib in

https://github.com/maas/python-libmaas/commit/e2660f5e4b560eced243dc295976ea6fe1d3bfdd

and it should be OK to remove python-oauth in jammy from this perspective, right?

[Athos Ribeiro (athos-ribeiro)]

I will start pushing this forward in https://bugs.launchpad.net/ubuntu/+source/python-oauth/+bug/1118815 since there are no objections here and MAAS seems to no longer use python-oauth
