Syncfile / Overwritten dataset after failed sync attempt

[ximenabb]

Describe the bug
Failed attempt to sync is still overwriting the syncfile when it shouldn’t, causing data to be lost/manipulated.

How to reproduce

1. On desktop, import custom config and record some data.
2. Export data as a syncfile
3. Clean up desktop so that you go back to default configuration
4. Attempt to sync with syncfile created in (2). It should fail
5. Import the same custom config used in (1)
6. Repeat (4). This time it seems like it works (no errors are surfaced), but notice that no database entries are being synced. Only media is synced.
7. If you look in the kappa.db folder, you’ll see media was successfully transferred over. You’ll also notice that the database file size has changed (probably decreased). Since syncfiles are two-way, step (6) essentially has removed the recorded database data from the syncfile, but the images remain. Those images will get ported over as you continue to use the same syncfile, accumulating “orphaned” images on the machine (i.e. images without associated db data)

Mapeo Version:

• Desktop - v.5.4.0
