Expected Behavior

If the underlying database file changes for whatever reason, KeePassXC should detect this and prompt to merge those changes prior to saving.

Current Behavior

This works sometimes using the file watcher construct. However, it often fails for USB drives and network shares.

Possible Solution

Store a hash of the database file when opening and after every save. Compare this hash to one developed just prior to saving and trigger actions if they differ.

Steps to Reproduce (for bugs)

  1. Create database, store on SMB share
  2. Open database on another computer, make changes
  3. Make changes on original computer, save
  4. Data is lost

Every database that has been opened now watch's it's own file. This allows the database class to manage file changes and detect fail conditions during saving. Additionally, all stakeholders of the database can listen for the database file changed notification and respond accordingly.

Performed significant cleanup of the autoreload code within DatabaseWidget. Fixed several issues with handling changes due to merging, not merging, and other scenarios while reloading.

Prevent database saves to the same file if there are changes on disk that have not been merged with the open database.
