Resizing terminal causes promptSecret to crash

[finleyjb]

Describe the bug

promptSecret appears to crash if I resize my terminal

Steps to Reproduce

1. Open deno repl
2. Run import { promptSecret } from "jsr:@std/cli"; promptSecret();
3. See the secret prompt
4. Resize your terminal window

This gives the following error:

Uncaught Interrupted: Interrupted system call (os error 4)
    at readSync (ext:deno_io/12_io.js:37:22)
    at Stdin.readSync (ext:deno_io/12_io.js:138:12)
    at readLineFromStdinSync (file:///home/fin/src/std/cli/prompt_secret.ts:85:21)
    at promptSecret (file:///home/fin/src/std/cli/prompt_secret.ts:65:12)
    at <anonymous>:1:22

Expected behavior

The promptSecret function should continue to run without throwing an error

Environment

This is running in the Tabby command-line app accessing Deno in a WSL Debian environment. I have not verified it in any other environments, so it might be a quirk due to this specific setup.

• OS: Windows 11 24h2, Debian 12
• deno version: 2.1.4
• std version: @std/cli v1.0.9

It looks like the root cause is Deno.stdin.readSync. The following also crashes if I resize the terminal.

> let buf = new Uint8Array(100);
> Deno.stdin.readSync(buf);

Note that this only seems to be a problem with the repl. If I run the following script and resize my terminal, it works as expected:

let buf = new Uint8Array(100);
Deno.stdin.readSync(buf);
