Terminal is unresponsive after running Vite

[bartlomieju]

running deno task dev in a vite project and stopping the devserver with ctrl-c the terminal does not accept keyboard input afterwards for me (manjaro linux, bash)

I'm using Manjaro Linux with zsh and I can confirm this issue as well.

Steps to reproduce:

1. run deno run npm:create-vite test and when prompted accept all permissions
2. cd test && deno task dev
3. Stop the process with Ctrl-C
4. run deno run npm:create-vite test again, this time when prompted for permissions Ctrl-C will print in the console instead of stopping the process.

I have the same issue in WSL2 Ubuntu 22 bash

I'm pretty sure this is the same problem as #16928

I found test cases in Node that check for this behavior:

• test/pseudo-tty/test-set-raw-mode-reset.js
• test/pseudo-tty/test-set-raw-mode-reset-signal.js
• test/pseudo-tty/test-set-raw-mode-reset-process-exit.js
  We should match this behavior in both Node polyfills and Deno APIs.

Any updates on this? #16928 seems to have been merged (and presumably released?) but I am experiencing this behavior with deno 1.37.1 on macOS 13.6, arm64, macports, bash 5.2.

Interestingly if I switch my shell from bash to zsh the shell will continue to echo after exiting the dev server, but the stty configuration has still subtly changed.

bash:

> deno run -A npm:create-vite-extra vite
✔ Select a template: › deno-svelte
✔ Select a variant: › TypeScript

Scaffolding project in /Users/wryfi/tmp/deno-test/vite...

Done. Now run:

  cd vite
  deno task dev

> cd vite
> stty
speed 38400 baud;
iutf8
-iexten
> deno task dev
> # `stty` again but nothing echoes
speed 38400 baud;
min = 1; time = 0;
-brkint -icrnl iutf8
-isig -icanon -iexten -echo

zsh:

> stty
speed 38400 baud;
iutf8
-iexten
> deno task dev
> stty
speed 38400 baud;
-brkint -icrnl iutf8
-isig -iexten

I believe this is now fixed thanks to #20892
