Editor temp files breaks auto reloading due to a `ValueError: <file> is not in the subpath of '.'`

[frmdstryr]

I have a simple aiohttp app in a package solarpi. When run using adev runserver solarpi and making a change my editor (KDevelop) sometimes creates temporary .kate-swp files that cause the following error:

[08:38:02] '/home/usr/projects/solar-pi/solarpi/templates/.index.html.kate-swp' is not in the subpath of '.'
Traceback (most recent call last):
  File "/home/usr/.local/share/mamba/envs/solarpi/lib/python3.13/site-packages/aiohttp_devtools/runserver/watch.py", line 97, in _run
    await src_reload(self._app, changes.pop()[1])
  File "/home/usr/.local/share/mamba/envs/solarpi/lib/python3.13/site-packages/aiohttp_devtools/runserver/serve.py", line 221, in src_reload
    path = str(Path(app[STATIC_URL]) / Path(path).relative_to(app[STATIC_PATH]))

ValueError: '/home/usr/projects/solar-pi/solarpi/templates/.index.html.kate-swp' is not in the subpath of '.'

After this error reloading stops working. Adding a try/except around that appears to fix the issue.

Does the error happen with watchfiles 1.0.4? I'm trying to understand why the path there is ".".

[frmdstryr]

It looks like I have 1.0.4, so yes:

$ pip list | grep watchfiles
watchfiles         1.0.4

Does the test I added produce the error for you (if you remove the try/except that is)?

[Dreamsorcerer]

Why are you setting the STATIC_PATH to .? Surely you'd encounter the same error when editing any file, including static ones, thus breaking the reload logic.

[Dreamsorcerer]

For comparison, I'm running an app like this:

adev runserver some_app -s some_app/static/

[frmdstryr]

I'm not setting app's STATIC_PATH anywhere that I know of. In my app It just does this.

routes = web.RouteTableDef()
routes.static('/static', os.path.join(os.path.dirname(__file__), 'static'))

Edit: Here's the whole module solarpi.tar.gz

If you're not setting it as part of the runserver command as I demonstrated above, then maybe there's a bug where it tries to do static reloading when you haven't enabled a static path. I'll test it out later and try and fix.

But, in your case, it looks like you do have a static path and you should be passing it to the command. Looking back at the README, I see it doesn't mention the parameter and still claims that it'll reload on static files, so I think that needs fixing too.

The help argument also says if excluded static files aren't served. I'm not sure if that's correct, I've always used the static argument for as long as I can remember..
