Resize event on stdout not invoked in TTY on macOS

[samholmes]

Version: Deno 2.0.4
macOS: 14.2.1

Repro steps

1. deno in Alacritty
2. process.stdout.on('resize', () => { console.log(${process.stdout.columns}x${process.stdout.rows}) })
3. Resize Alacritty window

Expected

Printed console output with the process columns and rows.

Actual

Nothing happens.

Additionally

If you run the same process.stdout.on('resize', () => { console.log(${process.stdout.columns}x${process.stdout.rows}) }) in node (I'm using v20), then you'll see the expected results.

Also, I've tested in Warp and Terminal TTY apps as well and got the same bug.

Update:

PR #27363 hooks up resize signal listeners, this works with deno run and friends.

It didn't work on REPL because rustyline would swallow SIGWINCH signals. Switching to the rustyline signal_hook features fixes the issue in the REPL.

Unfortunately, this causes PTY-based repl tests to timeout because reads would never appear. https://github.com/denoland/deno/actions/runs/14018704803/job/39247719404?pr=27363
