Title: fsspec: support fsspec>=2023.12.0 glob changes
Author: pmrowla (CONTRIBUTOR)
State: closed
Created: 2024-02-22T08:59:32Z

- adds support for the `fs.glob` changes introduced in `fsspec==2023.12.0` and unpins the current upper bound

Should close #6644
Should close #6645

The `test_data_files` glob/pattern tests pass for me in:
- `fsspec==2023.10.0` (the pinned max version in datasets `main`)
- `fsspec==2023.12.0` (#6644)
- `fsspec==2024.2.0` (#6645)

Comments:
The docs for this PR live [here](https://moon-ci-docs.huggingface.co/docs/datasets/pr_6687). All of your documentation changes will be reflected on that endpoint. The docs are available until 30 days after the last update.

Looking into the CI failure, this PR is incompatible with `huggingface-hub>=0.20.0`. It looks like there were several changes made to HfFileSystem in 0.20.0, @lhoestq any ideas on what the issue might be in particular?

a bisect indicates that it's related to https://github.com/huggingface/huggingface_hub/pull/1815

It looks like huggingface-hub's `HfFileSystem.glob` is broken for exact string matches (that don't contain glob wildcards) when combining `huggingface-hub>=0.20.0` and `fsspec>=2023.12.0`.

I did a quick test with huggingface-hub `main`, and adding this test case to `tests/test_hf_filesystem::HfFileSystemTests::test_glob` (https://github.com/huggingface/huggingface_hub/blob/main/tests/test_hf_file_system.py) passes with `fsspec==2023.10.0` and fails with `fsspec==2023.12.0`
```python
        self.assertEqual(
            sorted(self.hffs.glob(self.hf_path + "/.gitattributes")),
            sorted([self.hf_path + "/.gitattributes"]),
        )

```

the `hffs.glob()` call with a pattern that does not contain any wildcards returns an empty list:
```
E       AssertionError: Lists differ: [] != ['datasets/__DUMMY_TRANSFORMERS_USER__/rep[35 chars]tes']
E
E       Second list contains 1 additional elements.
E       First extra element 0:
E       'datasets/__DUMMY_TRANSFORMERS_USER__/repo-7d0ae9-17091013467064/.gitattributes'
E
E       - []
E       + ['datasets/__DUMMY_TRANSFORMERS_USER__/repo-7d0ae9-17091013467064/.gitattributes']
```
(and with the compatible/passing older fsspec versions the glob call returns the single exact file match as expected)

So it looks like the CI failure here isn't directly related to this PR. The failing patterns that don't contain any `*` wildcards are generated by `datasets` with or without this PR, but now that this PR installs the incompatible fsspec version, the underlying `HfFileSystem.glob()` call ends up failing.

I just opened https://github.com/huggingface/huggingface_hub/pull/2056 to fix this.

Do you mind if I continue this PR to run the CI against `huggingface_hub@main` until the fix is released ?

EDIT: the fix has been released in `huggingface_hub` 0.21.2 - I removed my commits that were using `huggingface_hub@main`

I just added two additional patterns to cover cases like `test-data/xxx.csv` and `data-test/xxx.csv`
