…ut restart "Run... Customized" with "Restart shell" unchecked restarted the shell anyway when it was busy executing code, killing any pending input. It now reports that the shell is executing and does not run.

With the patch, the message is displayed just once instead of twice. I added a draft doc issue on the project page to maybe say something in the doc. |

The
AttributeErrorin the original report (bpo-38002) was fixed by bpo-42508. This addresses the remaining problem noted by @terryjreedy: with the Shell busy executing code (e.g. blocked oninput()), using "Run... Customized" with "Restart shell" unchecked restarted the subprocess anyway.run_module_eventskips the explicitrestart_subprocesswhen restart is unchecked, butruncodethen restarts the busy shell on its own, overriding the user's choice and killing the pending input.The new code cannot run in the busy shell's namespace without restarting it, so when restart is unchecked and the shell is executing it now reports "Already executing" and aborts, instead of restarting anyway.
