Zarr version

2.17.0

Numcodecs version

0.12.1

Python Version

3.12.1

Operating System

Fedora 39/40/Rawhide

Installation

pip into virtual environment; also from source

Description

When testing against fsspec 2024.2.0, some hierarchy tests fail. These tests passed with 2023.12.2 (the previous release).

Steps to reproduce

$ python -m venv venv
$ . venv/bin/activate
$ pip install pytest zarr
$ pip install fsspec==2023.12.2
$ pytest --pyargs zarr.tests.test_storage  # All tests pass.

but then with fsspec 2024.2.0:

$ pip install fsspec==2024.2.0
$ pytest --pyargs zarr.tests.test_storage
