# Objective Fixes #28398 ## Solution This issue was occurring because `ProjectSearch` stored `Entity<MultiBuffer>` with has reference counted pointers to underlying buffers The function `remove_deleted_buffers` is renamed to `remove_stale_buffers` and it now also checks for buffers which do not have a file associated with them and are closed. Then, it removes them from `Entity<MultiBuffer>` stored in ProjectSearch. This function is also called in again when workspace is upgraded. ## Testing Bug being fixed was manually verified. ## 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 Release Notes: - Fixed project search retaining results from closed untitled buffers. --------- Co-authored-by: Kirill Bulatov <kirill@zed.dev> Co-authored-by: zed-zippy[bot] <234243425+zed-zippy[bot]@users.noreply.github.com>
