Environment data

• VS Code version: 1.30.1
• Extension version (available under the Extensions sidebar): 2018.12.1 (14 Dec 2018)

Expected behaviour

On pressing Ctrl + Space, all members of the module should be populated

Actual behaviour

On pressing Ctrl + Space, VS is stuck at loading... and on pressing backspace starts to show module members

Steps to reproduce:

1. Create a new python file and import any well-known package
2. Type os. and press Ctrl + Space
3. Press backspace and clear the (.)
4. Now add the (.) and type sys (for os.system) and press Ctrl + Space
5. While Loading.. is being displayed hit backspace until only one character is left to the right of the (.) --> os.s ==> now all the data members show up

Settings:

{
"python.jediEnabled": false,
"python.linting.pylintEnabled": false,
"python.autoComplete.addBrackets": true,
"terminal.integrated.shell.windows": "C:\WINDOWS\System32\cmd.exe",

"diffEditor.renderSideBySide": false,
"explorer.confirmDelete": true,
"terminal.integrated.rendererType": "dom",
"workbench.iconTheme": "vscode-icons",
"python.autoUpdateLanguageServer": true
}

Note: all paths have double \ . Paths do not have any issues

Hi @rohansekhri. Thanks for letting us know about this. I haven't been able to reproduce the problem using Linux, so I wonder if it is Windows-specific. Also, how long has this been a problem for you? For instance, did it start happening after an update or has it always been this way?

[rohansekhri]

I have seen it a few times and I haven't been coding on Linux for a while so I'm not sure of the behavior on Linux. Is there something needed in addition to what I have already provided?

Could you try updating the language server to the latest stable version?
