Compatibility with Python 3.12

[amotl]

Hi there,

thank you very much for conceiving and maintaining the geojson package.

We are currently evaluating support for Python 3.12 on behalf of https://github.com/earthobservations/wetterdienst/pull/1008, and wanted to report an observation we just made over there ^1:

SolverProblemError

The current project's Python requirement (3.12.0rc3) is not compatible with some of the required packages Python requirement:
- geojson requires Python >=3.7, <3.12, so it will not be satisfied for Python 3.12.0rc3

Because geojson (3.0.1) requires Python >=3.7, <3.12
and no versions of geojson match >=3,<3.0.1 || >3.0.1,<4, geojson is forbidden.
So, because wetterdienst depends on geojson (>=3,<4), version solving failed.

Python 3.12 will be released on 2023-10-02 ^2, so, if nothing speaks against it, it might be applicable to relax the version constraint, and run another release in order to unlock a few other applications depending on geojson?

With kind regards, Andreas.

This restriction was relaxed to 3.7 - 3.12 in https://github.com/jazzband/geojson/pull/215 (although I don't think there should be any upper bound).

What is missing is a release to PyPI.

@rayrrr After #222 is merged, please could you make a new release?

Hi again,

thank you for integrating GH-222 so quickly, @hugovk.

The package can now be installed well interactively, as a workaround, by invoking pip install git+https://github.com/jazzband/geojson, but it can't be used as a dependency in setup.py / setup.cfg / pyproject.toml, unless it will be released on PyPI, right?

So, in order to support the advent of Python 3.12, can we humbly ask you to run a release on PyPI?

With kind regards, Andreas.

[hugovk]

Yes, it's possible.

Here's an example: https://peps.python.org/pep-0508/#examples

For example in pyproject.toml:

dependencies = [
  "geojson @ https://github.com/jazzband/geojson/archive/refs/heads/main.zip",
]

Note this installs from a zip which should be quicker than from a Git clone.

What’s blocking to make a proper Pypi release?

[rayrrr]

New release forthcoming. I just need to write up the changelog and push it out. Will aim to get it done by this weekend at the latest.

3.1.0 has been released with Python 3.12 support. https://pypi.org/project/geojson/

Dear Ray,

thank you so much for running a release ❤️. On two downstream projects, we've invoked corresponding CI runs. It seems to work well [^1].

• https://github.com/crate/crate-python/pull/592
• https://github.com/earthobservations/wetterdienst/pull/1008

With kind regards, Andreas.
