Add a Qt6 compatibility check when releasing a version

[florentfougeres]

Goals

The purpose of this PR is to run the Qt6 compatibility script pyqt5_to_pyqt6.py everytime when a new plugin version is uploaded. You can then access to the compatibility result in the web interface.

Our goal is to enforce the QGIS 4 compatibility for new plugins. It was already discussed in QEP #287 (see Trigger linters on plugins.qgis.org)

This is still a work in progress, tests and mail notifications are missing. I'd like to check that the overall looks good before continuing any further.

I'm aware of #266 and I'm prepared to rebase this work on it once merged. I'm wondering if Qt6 compatbility tests shall be synchronous with the #266 ones. This could be tricky because they require to be run in the appropriate docker environnement. I'm open to suggestions.

To sum up this PR:

• Starts a new docker from https://github.com/qgis/pyqgis4-checker/ which contans the script pyqt5_to_pyqt6.py
• Triggers a celery task to run the script inside this docker when a new plugin version is created
• Save the results in the database once the script is finished
• Display the results in a table in a new tab in the version view

Thanks so much for this @florentfougeres . This looks awesome. I will try it locally to check out how it works and get back to you.

Thanks so much for this @florentfougeres . I was able to spin it locally (with some tweaks), and it's working as you described. This will definitely be a huge addition to the Plugins Website.

I've also reviewed the code implementation, and I have some suggestions/questions.

Thanks again!

Could you please explain why this (qt6-validator) is implemented outside the Django App?

[florentfougeres]

Since we need access to a QGIS installation with Qt6 and the pyqt5_to_pyqt6.py script, we use the Docker image provided by the pyqgis4-checker project. This allows us to keep it well isolated from the rest of Django.

We will also ask QGIS Container to flag deprecated methods in a future validator that we plan to release later (see this QEP)

If you have any other ideas for accessing this in a Django app, I’m of course open to any suggestions

[Xpirix]

Thanks for the explanation. That sounds fine.

[Xpirix]

I wonder if you could also please share your thoughts on this @timlinux ? Thanks!

[Xpirix]

It will also be appreciated if you could please add unit tests and perhaps add docs or update the Qt6 migration docs (https://plugins.qgis.org/docs/migrate-qgis4) for this new implementation @florentfougeres. Thanks!

[timlinux]

This is a really great addition, thank you for sharing @florentfougeres - happy for @Xpirix to merge when he is happy with the code quality.

[florentfougeres]

Thanks @Xpirix for the review. I'll take the time to reply to you and make the necessary changes next week.

The overall changes look good to me!

Are you still planning to add these to this PR?
