- fix(autosave): every time the typing stops
- chore(refactor): document tracking into provideSyncService
- fix(autosave): only save when server is ready
- fix(autosave): better dirty tracking with versions
- chore(refactor): Save service with its own bus
- chore(refactor): separate SaveService from SyncService and ydoc
- fix(autosave): exponential delay for retries on error
- fix(autosave): retry if server throttled save request
- fix(autosave): handle out of sync clocks
Debounce will delay the execution of the function every time it is called. So autosave was waiting until no updates occured for 30 seconds. That's a long time and does not feel responsive. Try to autosave every time the user stops typing for at least one second. Signed-off-by: Max <max@nextcloud.com>
Also removed the document attribute from the `sync` event load. It is already included in the `change` event load. Signed-off-by: Max <max@nextcloud.com>
The server will only accept autosaves every 10 seconds. `document` contains the last saved timestamp. Compute the time to autosave next. Add a small random delay (up to 3 seconds) to avoid all connected clients from saving at the same time. Signed-off-by: Max <max@nextcloud.com>
Keep track of the version that has our changes and compare it to the last saved version on the server. This allows fixing two scenarios: * Server response happily to save but does not actually save. The server will only save new versions every 10 seconds. If the latest save just happened it will still respond with 200 but list the outdated version in the response. Comparing the versions shows that our changes have not been saved yet. * Other user already saved the file. our changes. So far dirty would stay true until WE save our changes. Comparing the versions also shows the file was saved when it was saved by someone else. Signed-off-by: Max <max@nextcloud.com>

* `getSaveData` now prepares the data to send to the server. * `provideSaveService` now handles all the sync service events calling functions on `saveService` where needed. Signed-off-by: Max <max@nextcloud.com>

The server will only perform one actual save every 10 seconds. Trigger another autosave if the save attempt was throttled. `document` is udpated by throttled save attempts. Rely on its `lastSavedVersionTime` for the retry. Signed-off-by: Max <max@nextcloud.com>
* If the server claims to have saved the doc in the future use the current timestamp instead. Autosave happens at least ten seconds after `lastSavedVersionTime`. So if that was far into the future it would never happen. * If the server is living in the past delay the autosave retries without relying on `lastSavedVersionTime`.
