const port =3000;

Unresolved thread: line +3

Graphite 1h ago

Logic bug
Change the port from 3000 to 8000 to match the exported port in the tests. The CI test is failing because it expects the server to run on port 8000.

Suggested change 

const port = 3000;
const port = 8000;

Commit suggestion
Update server.js

Logic bug

The condition in the if statement should be inverted. Change it to: 

if (!Object.keys(ASYNC_JOB_REGISTRY).includes(kind)) {

Potential edge case

readlink -f is not available on macOS by default. A more portable solution would be: 

filepath=$(perl -e 'use Cwd "abs_path";print abs_path(shift)' "$0")

This achieves the same result but works across both Linux and macOS environments.

Security issue

Please remove this token logging. Exposing GitHub access tokens in logs creates a security risk, as these tokens grant API access and should be treated as sensitive credentials.

Accidentally committed code

Adding || true to this condition causes the function to unconditionally return "BINARY", bypassing the binary detection logic. This appears to be unintentional and should be removed to restore the original file type detection behavior.

Performance

The await inside Promise.all([...]) is preventing parallel execution of these promises. Since Promise.all expects an array of promises, the await here will cause the stack dependency check to complete before the merge job query begins. To achieve the intended parallel execution, remove the await from db.stack.getStackDependencyForPr().

Code style/quality

The callsite value markNotifAsRead doesn't match the function name markAsReadEndpoint.

Documentation issue

The description 'Get auth tokens for user' doesn't match the command's actual functionality. Consider changing it to 'Run async job queue and send a test email'.
