Tests all pass now.

Tested that locally with Python 3.9 from pyenv and it worked.

Still fails in Python 3.9: https://github.com/simonw/datasette/actions/runs/6266752548/job/17018363302 plugin_info["name"] = distinfo.name or distinfo.project_name AttributeError: 'PathDistribution' object has no attribute 'name' Test failed: datasette-json-html should not have been loaded

That does seem to fix the problem!

Hunch: https://pypi.org/project/importlib-metadata/ may help here.

No that's not it actually, it's something else.

Got to this point: bash DATASETTE_LOAD_PLUGINS=datasette-init python -i $(which datasette) plugins That fails and drops me into a debugger:

File "/Users/simon/Dropbox/Development/datasette/datasette/cli.py", line 186, in plugins app = Datasette([], plugins_dir=plugins_dir) File "/Users/simon/Dropbox/Development/datasette/datasette/app.py", line 405, in __init__ for plugin in get_plugins() File "/Users/simon/Dropbox/Development/datasette/datasette/plugins.py", line 89, in get_plugins plugin_info["name"] = distinfo.name or distinfo.project_name AttributeError: 'PathDistribution' object has no attribute 'name'

The problem is here: 86 distinfo = plugin_to_distinfo.get(plugin) 87 if distinfo is None: 88 breakpoint() 89 -> assert False 90 if distinfo.name is None: 91 breakpoint() 92 assert False 93 if distinfo: 94 plugin_info["version"] = distinfo.version (Pdb) distinfo (Pdb) plugin <module 'datasette.sql_functions' from '/Users/simon/Dropbox/Development/datasette/datasette/sql_functions.py'> That plugin_to_distinfo is missing some stuff.

So the problem is the get_plugins() function returning plugins with None for their name:

https://github.com/simonw/datasette/blob/80a9cd9620fddf2695d12d8386a91e7c6b145ef2/datasette/plugins.py#L61-L91

Relevant code: https://github.com/simonw/datasette/blob/80a9cd9620fddf2695d12d8386a91e7c6b145ef2/datasette/app.py#L1127-L1146

In the debugger: ```

import pdb pdb.pm() /Users/simon/Dropbox/Development/datasette/datasette/app.py(1136)_plugins() -> ps.sort(key=lambda p: p["name"]) (Pdb) ps [{'name': None, 'static_path': None, 'templates_path': None, 'hooks': ['prepare_connection', 'render_cell'], 'version': '1.0.1'}, {'name': None, 'static_path': None, 'templates_path': None, 'hooks': ['startup'], 'version': '0.2'}] ```

In my Python 3.8 environment I ran: bash datasette install datasette-init datasette-json-html And now datasette plugins produces this error: File "/Users/simon/Dropbox/Development/datasette/datasette/cli.py", line 192, in plugins click.echo(json.dumps(app._plugins(all=all), indent=4)) File "/Users/simon/Dropbox/Development/datasette/datasette/app.py", line 1136, in _plugins ps.sort(key=lambda p: p["name"]) TypeError: '<' not supported between instances of 'NoneType' and 'NoneType'

That passed on 3.8 but should have failed: https://github.com/simonw/datasette/actions/runs/6266341481/job/17017099801 - the "Test DATASETTE_LOAD_PLUGINS" test shows errors but did not fail the CI run.

I'll imitate certbot:

https://github.com/certbot/certbot/blob/694c758db7fcd8410b5dadcd136c61b3eb028fdc/certbot-ci/setup.py#L9

python 'importlib_resources>=1.3.1; python_version < "3.9"', Looks like 1.3 is the minimum version needed for compatibility with the 3.9 standard library, according to https://github.com/python/importlib_resources/blob/main/README.rst#compatibility

https://github.com/certbot/certbot/blob/694c758db7fcd8410b5dadcd136c61b3eb028fdc/certbot/certbot/_internal/constants.py#L13C29-L16

python if sys.version_info >= (3, 9): # pragma: no cover import importlib.resources as importlib_resources else: # pragma: no cover import importlib_resources

I think I can fix this using https://importlib-resources.readthedocs.io/en/latest/using.html - maybe as a dependency only installed if the Python version is less than 3.9.

Confirmed: https://docs.python.org/3/library/importlib.resources.html#importlib.resources.files

importlib.resources.files(package) [...] New in version 3.9.

This broke in Python 3.8:

if plugin.__name__ not in DEFAULT_PLUGINS: try: if (importlib.resources.files(plugin.__name__) / "static").is_dir(): E AttributeError: module 'importlib.resources' has no attribute 'files'
