Closes #61346 # Objective At startup, a synchronous `try_recv` decides whether to restore the session. On a macOS cold launch the CLI request arrives via `application:openURLs:`, which AppKit dispatches only *after* the startup closure returns, so the check finds nothing, session restore begins, and the request lands moments later on the post-startup path. Both behaviors are individually correct: a user with `restore_on_startup: "last_session"` wants their session back, and the requested file should open. The defect is that they race, the CLI open runs its existing-window matching before restore has placed any windows, finds nothing to reuse, and opens a redundant window. ## Solution Make the post-startup open loop wait for restore to settle before handling a request, so `find_existing_workspace` sees the restored windows and honors `cli_default_open_behavior`. The wait races full restore completion against the first window being placed, so a slow or hung remote-workspace restore can't block a local open. No timeouts involved, the fix is ordering, not delay :). ## Testing **Steps**: 1. disable & enable the setting `close windows when quiting an application` in macos itself in `desktop & dock` section 2. create a bundled Zed app 3. install cli binary to actually test the change 4. Follow any of the steps inside the before/after video's to test all the cases we have I tested this with a manual prod build using a custom script that bundles Zed as a preview app. So I could actually test the cli baviour since it works different for non-bundled builds. So the easiest way to test this would be to run bundling on this PR and install the cli binary to actually test it with the fix included. ## Self-Review Checklist: - [x] I've reviewed my own diff for quality, security, and reliability - [x] Unsafe blocks (if any) have justifying comments - [x] The content adheres to Zed's UI standards ([UX/UI](https://github.com/zed-industries/zed/blob/main/CONTRIBUTING.md#uiux-checklist) and [icon](https://github.com/zed-industries/zed/blob/main/crates/icons/README.md) guidelines) - [ ] Tests cover the new/changed behavior - [x] Performance impact has been considered and is acceptable ## Showcase <details> <summary>**Disabled** Close windows when quiting an application</summary> **before** (disabled apps on close & `add to existing window` cli bahavior) https://github.com/user-attachments/assets/b497130b-3432-4fa8-9fbe-70c6f63d165e **After** (disabled apps on close & `add to existing window` cli bahavior) https://github.com/user-attachments/assets/354657f7-8dfe-4beb-9dd4-2bb615cb912c **After** (disabled apps on close & `open a new window` cli bahavior) https://github.com/user-attachments/assets/07fc3062-89a3-4e2a-811e-296533feaad7 </details> <details> <summary>**Enabled** Close windows when quiting an application (unchanged)</summary> **After** (enabled** apps on close & `add to existing window` cli bahavior (**unchanged**)) https://github.com/user-attachments/assets/445f1d3a-2987-46b1-9bfb-b2d61894ddec **After** (enabled apps on close & `open a new window` cli bahavior (**unchanged**)) https://github.com/user-attachments/assets/c3078b0d-7fb4-42db-9dea-095439e23830 </details> --- Release Notes: - Fixed an extra window opening on macOS when launching Zed from the CLI with session restore enabled |
