This adds the ability for Zed to restore unsaved buffers on restart. The user is no longer prompted to save/discard/cancel when trying to close a Zed window with dirty buffers in it. Instead those dirty buffers are stored and restored on restart. It does this by saving the contents of dirty buffers to the internal SQLite database in which Zed stores other data too. On restart, if there are dirty buffers in the database, they are restored. On certain events (buffer changed, file saved, ...) Zed will serialize these buffers, throttled to a 100ms, so that we don't overload the machine by saving on every keystroke. When Zed quits, it waits until all the buffers are serialized. ### Current limitations - It does not persist undo-history (right now we don't persist/restore undo-history regardless of dirty buffers or not) - It does not restore buffers in windows without projects/worktrees. Example: if you open a new window with `cmd-shift-n` and type something in a buffer, this will _not_ be stored and you will be asked whether to save/discard on quit. In the future, we want to fix this by also restoring windows without projects/worktrees. ### Demo https://github.com/user-attachments/assets/45c63237-8848-471f-8575-ac05496bba19 ### Related tickets I'm unsure about closing them, without also fixing the 2nd limitation: restoring of worktree-less windows. So let's wait until that. - https://github.com/zed-industries/zed/issues/4985 - https://github.com/zed-industries/zed/issues/4683 ### Note on performance - Serializing editing buffer (asynchronously on background thread) with 500k lines takes ~200ms on M3 Max. That's an extreme case and that performance seems acceptable. Release Notes: - Added automatic restoring of unsaved buffers. Zed can now be closed even if there are unsaved changes in buffers. One current limitation is that this only works when having projects open, not single files or empty windows with unsaved buffers. The feature can be turned off by setting `{"session": {"restore_unsaved_buffers": false}}`. --------- Co-authored-by: Bennet <bennet@zed.dev> Co-authored-by: Antonio <antonio@zed.dev> |
