Some static files are not served with Flask 2.0

[encukou]

Flask 2.0 seems to have made changes around serving static files, and Frozen-Flask's approach no longer finds all static files.

Working on a little more confirmation here, but it looks like this may relate to pallets/flask#3762 (included in Flask 2.x).

We use a test at

Frozen-Flask/flask_frozen/__init__.py

Lines 439 to 440 in 435bd1c

	if unwrap_method(view) is send_static_file:
	yield rule.endpoint

to check whether each view function is the same as the send_static_file method, and yield the matching endpoint names.

With the introduction of the lambda function 'in front' of the send_static_file method, the equality check will not pass, the static endpoint is skipped from the list of Frozen-Flask static rules, and the contents aren't retrieved for freezing into the resulting document set.

Because it didn't seem clear how Flask-Frozen could fix this easily, I thought it might be worth asking the flask community whether they have any ideas or suggestions.

This has been opened as a GitHub discussion (filed as Q&A) here: pallets/flask#4136

Hi @jayaddison, this is amazing work, thank you so much! I haven't had much time lately to assist here, I'm sorry for that.

[jayaddison]

No problem at all @honzajavorek; thanks for maintaining the library. I'd offer some time if I could, but not sure I can promise much; I'll try to check in on the health of frozen-flask when possible.

I'd be happy to see you around! Thank you for the work on this issue, I think that was already an excellent way how you helped this project :)
