Unwanted execution of KeyboardInterrupt . #25468
Description
Type: Bug
Behaviour
I updated the extension to Python v2025.14.0. When I run shift+enter, KeyboardInterrupt appears in the terminal. When I return to the previous version, this does not happen.
Steps to reproduce:
Python 3.12.3 (main, Aug 14 2025, 17:47:21) [GCC 13.3.0] on linux
Type "help", "copyright", "credits" or "license" for more information.

Hi! Can you update to the newest version for the python environments extension and try it again? I think I merged in a code change that should help with this. If not, please return the command you are trying to execute, and what happens when you do so from the terminal (as we look to replicate that experience).
marciomocellin commentedon Sep 22, 2025
Unfortunately, it still happens. I verified that the unintended triggering of
KeyboardInterruptstarted with the pre-release versionPython v2025.13.2025080801 (pre-release). The behavior was not present in earlier builds.Python v2025.15.2025092201 (pre-release)

Márcio Mocellin (@marciomocellin) What happens if you set
python.terminal.shellIntegration.enabledto false?If that doesnt work, what happens if you set terminal.integrated.shellIntegration.enabled to false?

I have the same problem, with a keyboard interrupt in the REPL (with
shift+enter).It also happens in a regular terminal. I'm mid-command, and I get interrupted by the command
^C; & C:\...\.venv\Scripts\Activate.ps1which takes a few seconds to come.The worst is that it kills the debugger the first time the debug terminal opens.
I have to launch it again every time this terminal is closed.

I suspect this is better (at least for executing via shift+enter) with https://code.visualstudio.com/updates/v1_106#_consolidated-shell-integration-timeout-setting but it may not be enough.
I think we need a better fix. I will look into this and share any updates here, thanks all.
Fix KeyboardInterrupt in REPL (microsoft#25625)
anthonykim1 commentedon Dec 4, 2025
I believe this should be fixed with #25625
Please give it a try on the latest VS Code Insiders:
Insiders build?
And using Python extension PRE-Release version.

Same here. Keyboard interrupt when I run Python code with or without debugging. A immediate rerun attempt is successful without any issues.
LeFanch commentedon Mar 29, 2026
Same here, (exactly same as snympi), since 1 to 3 weeks :
