[BUG] `Python: Restart Language Server` command fails to start the language server after shutdown #24218

Closed tboddyspargo closed 2 weeks ago

tboddyspargo commented 2 weeks ago

Type: Bug

Behaviour

I'm in a multi-root workspace. I use the command palette to run Python: Restart Language Server its failing to re-index my workspace. It fails to start up the language server again. Perhaps due to a failure to merge config values from my code-workspace file into its runtime config?

Steps to reproduce:

  1. Open the command palette
  2. Run Python: Restart Language Server

Diagnostic data

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)
