Repro Steps

I've recently noticed VS Code isn't indexing my Python files properly - find usages and workspace symbol search aren't working. My code is inside a src directory.

Looking at the logs, I see:

If I add the directory manually to python.analysis.include, I see:

[Info  - 4:07:30 PM] (7229) Searching for source files
[Info  - 4:07:30 PM] (7229) Found 85 source files

and "Show references" starts working. This used to work before out of the box, so I'm assuming src isn't being scanned by default any more? The docs seem to imply it should be.

[debonte]

@Tinche, any chance you have set:

"python.analysis.diagnosticMode": "workspace",

Wondering if you might be seeing #3343.

[Tinche]

Negative, my global and workspace settings do not reference that key :(

[debonte]

Ok, and I'm assuming you don't have python.analysis.autoSearchPaths set to false, since I believe it's the docs for that config setting that you were referring to when you said, "The docs seem to imply it should be."

Is there an __init__.py in your src directory?

If not, could you set "python.analysis.logLevel": "Trace", restart Pylance, and then provide a new "Python Language Server" log?

[Tinche]

Oh, interesting, my src does not have an __init__.py. We're using namespace packages since some other code is in the same package, but another directory.

Here's the full log with logLevel: Trace:

Apparently, we do not automatically search src if it contains an __init__.py. Anyway, that's why I asked. But you're good there.

Hmmm, the log shows that we are adding src to the search path.

Is this code in a public repo that I can try out on my machine?

[Tinche]

No, it's a private repo, but I could try paring it down as much as I can while still reproing and then publishing it somewhere.

[Tinche]

I whittled it down to https://github.com/Tinche/vs-code-test.

Still says No source files found. unless I explicitly add src to python.analysis.include, then it says Found 1 source file.

[debonte]

Excellent, thanks! I can repro the issue.

I don't see it in 2022.9.10 (last week's release), so you could work around the issue by switching to that build.

[Tinche]

Glad I could help and thanks for looking into this ;)

[debonte]

This issue has been fixed in prerelease version 2022.9.31, which we've just released. You can find the changelog here: CHANGELOG.md

[Tinche]

Thanks!
