📝 Walkthrough

Walkthrough

The default IPC socket filename is renamed from webpack-dev-server.sock to rspack-dev-server.sock in src/server.ts. This change applies only when options.ipc is set to true (boolean); all other IPC path-handling logic is unchanged. Two corresponding assertions in tests/e2e/ipc.test.js are updated to expect the new rspack-dev-server.${process.pid}-N.sock filename pattern.
