Conan: [question] why isn't python requires updated with --update?

[Mark-Hatch-Bose]

To help us debug your issue please explain:

• [x] I've read the CONTRIBUTING guide.
• [x] I've specified the Conan version, operating system version and any tool that can be relevant.
• [x] I've explained the steps to reproduce the error or the motivation/use case of the question/suggestion.

Conan Version 1.12.2
Distributor ID: Ubuntu
Description:    Ubuntu 16.04.5 LTS
Release:    16.04
Codename:   xenial

I see from documentation at:
https://docs.conan.io/en/latest/extending/python_requires.html

That python_requires are not updated with --update
They are not automatically updated with the --update argument from remotes.

But why? Every time I update the python_requires I need to inform all users to clear their cache for those packages to be updated? Seems very cumbersome.

[memsharded]

The main reason was that due to the "inversion of control" that is necessary to process python-requires, passing user information to the resolution of python-requires was quite ugly.

The architecture has improved a little bit, so I think it is possible, adding self.update and self.check_updates to ConanPythonRequires, I'll submit a draft PR, to be considered for 1.14

[memsharded]

Implemented. This will be released in next Conan 1.14.
Thanks for raising this issue!

@memsharded This is still not functioning. conan version 1.15.1

I'm using python requires in the manner described here:
https://docs.conan.io/en/latest/extending/python_requires.html#python-requires-reusing-code-experimental

I'm defining base ConanFile recipes, which works great!

In my downstream conanfiles:

common = python_requires('ConanRecipes/[>=0.1.0-0, include_prerelease=True]@mh/testing')

class ThisIsAPackage(common.BaseRecipe):

However, it still does not get updated with --update
I have to remove the ConanRecipes locally to get latest version.

conan remove ConanRecipes* -f

Then it downloads the latest one.
