Analysis Engine Errors with URI

[DonJayamanne]

The following errors are getting logged in VSC by the Analysis Engine and none of the analysis engine features work:

  ERR [UriError]: If a URI does not contain an authority component, then the path cannot begin with two slash characters ("//"): Error: [UriError]: If a URI does not contain an authority component, then the path cannot begin with two slash characters ("//")

You need #1934 to match the engine

[DonJayamanne]

Step to reproduce:

• Open any folder with python files
• Create a virtual environment in this folder virtualenv --python=python3.6 venv
• Reload VS Code

Not sure if it's related but I'm getting these errors when trying to use the new analysis engine

[Error - 2:37:47 PM] Request textDocument/documentSymbol failed.
  Message: This operation is not supported for a relative URI.
  Code: -32000

This is using the latest development version of vscode-python that seems to include #1934.

@albireox Are you using Python 2?

[albireox]

I get that message when the interpreter is set to 3.6.5. In a different package with 2.7.15 I get

[Error - 7:49:45 AM] Request textDocument/documentSymbol failed.
  Message: Object reference not set to an instance of an object.
  Code: -32000

Please delete the Analysis directory for the extension and then reload VS Code to trigger a fresh download (some changes landed recently which I think might help with this).

[albireox]

No, I removed ~/.vscode-insiders/extensions/ms-python.python-2018.6.0-beta/analysis which triggered the analysis engine to be downloaded again but that didn't solve the problem. Worth saying the the completion works fine (apparently), it's just the annoying output message.

[albireox]

Not sure if something changed in the analysis engine but I tried again a bit ago and it seems to be working now.

[MikhailArkhipov]

OK, that one is fixed in microsoft/PTVS#4399
