Decide handling of unusual file names

[MikhailArkhipov]

Technically file names are module names and names like 1.py or a-b.py are unimportable. Currently we fail with Unable to find document message which is not informative.

Options:

1. Give informative warning message (or make it error and then fail).
2. Make files work in standalone way (with warning).

It is actually one fix for this one and #597: file that has name that can't be a module can have name and be analyzed (including absolute imports).

[jakebailey]

I'm not sure they're completely identical; I could have a file in some directory called a.py and my-script.py next to it which does from .a import foo and execute the latter just fine, right? The difference I'm seeing is that I think the assumption we'd make for #597 is to pretend untitled files are at the root, but I don't think that's so for the my-script.py case. I'd need to test and see what'd happen; this is just my initial thought.

[AlexanderSher]

If you do python my-script.py, you'll get an error:

cannot import name 'a' from '__main__' (my-script.py)

[jakebailey]

Yes, I did some testing and things do seem to break. Though it looks like you can actually do python -m my-script and it works. My choice in using a relative import was probably a bad one; so I tested using absolute which also failed. Maybe it won't matter all that much, I was just worried about removing potentially important info about where a file exists.

For completion's sake, if you're curious:

#778 too: We should be handling files without .py at the end in a similar fashion.

Files that start with [0-9] also don't seem to be working..Keep getting the following prints:

Unfortunately I am still getting errors Unable to find document file

:CocCommand python.upgradePythonLanguageServer

Upgrading to latest stable solved the issue.
