Dockerode attach hangs

[pwilkin]

What version of Bun is running?

1.2.8+adab0f64f

What platform is your computer?

Linux Ubuntu 24.10

What steps can reproduce the bug?

Create the following Jest test:

import Docker from 'dockerode';

describe("Dockerode", () => {
    it("should run a container", async () => {        
        const docker: Docker = new Docker();
        process.env.DEBUG = "dockerode:*";

        try {
            const container = await docker.createContainer({
                Image: 'python:3.12-bookworm',
                Cmd: ['/bin/bash', '-i'],
                Tty: true,
                AttachStdin: true,
                AttachStdout: true,
                AttachStderr: true,
                OpenStdin: true,
                StdinOnce: false,
            });
            await container.start();

            const logs = await container.logs({
                stdout: true,
                stderr: true,
                follow: false,
            });
            console.log(logs.toString());

            console.log("Boo");
            const stream = await container.attach({
                stream: false,
                stdin: true,
                hijack: true, // include hijack for a proper upgrade (even if it didn’t help before)
            });
            console.log("Boo2");

            // When the "READY" marker has been printed by the shell, you’ll see it on STDOUT.
            stream.setEncoding('utf-8');
            stream.on('data', (chunk) => console.log('STDOUT:', chunk));

            // Now send your command:
            stream.write('echo "Hello, World!"\n');
        } catch (error) {
            console.error('Error running Docker IRF:', error);
        }
    });
});

The test hangs after "Boo":

ilintar@LinuksowaJaskinia:/mnt/win/h/aidev/ts-src$ bun test "/mnt/win/h/aidev/ts-src/test/basic.test.ts" -t "Dockerode"
bun test v1.2.8 (adab0f64)

test/basic.test.ts:

Boo
^C
ilintar@LinuksowaJaskinia:/mnt/win/h/aidev/ts-src$ bun test "/mnt/win/h/aidev/ts-src/test/basic.test.ts" -t "basic"^C
ilintar@LinuksowaJaskinia:/mnt/win/h/aidev/ts-src$ npx jest test/basic.test.ts 
  console.log


      at Object.<anonymous> (test/basic.test.ts:26:21)

  console.log
    Boo

      at Object.<anonymous> (test/basic.test.ts:28:21)

  console.log
    Boo2

      at Object.<anonymous> (test/basic.test.ts:34:21)

 PASS  test/basic.test.ts
  Dockerode
    ✓ should run a container (146 ms)

Tests:       1 passed, 1 total

Ran all test suites matching /test\/basic.test.ts/i.

What is the expected behavior?

The test should complete correctly writing "Boo" and "Boo2" on the console.

What do you see instead?

Test hangs on container.attach(...).

I noticed this as well.

[hg0428]

Works fine with Node.

Yep, I setup Jest and retested it with npx jest to see if it was Bun-specific before adding this issue.
