Bug with Python 3.12

[mgrover1]

As of now, several components break with Python 3.12. Here is a sample of the output after installing Python 3.12 in the datatree dev environment. It appears to be related to pathlib, but I am not exactly sure. Any thoughts here?

Uh oh! Perhaps it wasn't so clever to subclass a class from the pathlib standard libary 😅

[mgrover1]

@TomNicholas - from the highlights, it looks like subclassing the pathlib.Path class is now supported directly

Significant improvements in the standard library:

The pathlib.Path class now supports subclassing

The os module received several improvements for Windows support

A command-line interface has been added to the sqlite3 module

https://docs.python.org/3/whatsnew/3.12.html

[TomNicholas]

Oh interesting! I deliberately didn't subclass Path though because (a) these paths should not be linked to the filesystem and (b) I don't want the direction of the separator slashes flipping on Windows systems. (Also do the docs clearly state which classes do and don't support subclassing...?)

[mgrover1]

Those are great questions... I am not sure. Also it is unclear of what exactly changed here that is causing the lack of those methods...

[mgrover1]

@TomNicholas from further down the page:

Add support for subclassing pathlib.PurePath and pathlib.Path, plus their Posix- and Windows-specific variants. Subclasses may override the pathlib.PurePath.with_segments() method to pass information between path instances.

[mgrover1]

@TomNicholas - how difficult of a fix would you think this would be? I am happy to help where possible.

[TomNicholas]

how difficult of a fix would you think this would be? I am happy to help where possible.

Probably really easy - I suspect that we would just need to rewrite NodePath to initialize using whatever the newly-recommended approach is. (Looks like we can just use __init__ now.) NodePath doesn't even add any functionality on top of using PurePosixPath, it just forbids some obviously-invalid path strings, so we can just keep those checks in the new __init__.

To make it work on different versions of python I think we would need to wrap the definition of NodePath within an if else check of sys.version.

It might also be good to add a test that specifically checks that we can create a NodePath object and successfully do whatever it is that causes those errors (looks like simply viewing the repr?)

[mgrover1]

@TomNicholas - once #260 is merged, would you be willing to cut a new release for datatree, which would release 3.12 wheels?
