// NOTE: when synchronising with the file system the time resolution is the second (unlike milliseconds for OneDrive for instance).
|
|
|
|
// What it means is that if, for example, client 1 changes a note at time t, and client 2 changes the same note within the same second,
|
|
|
|
// both clients will not know about each others updates during the next sync. They will simply both sync their note and whoever
|
|
|
|
// comes last will overwrite (on the remote storage) the note of the other client. Both client will then have a different note at
|
|
|
|
// that point and that will only be resolved if one of them changes the note and sync (if they don't change it, it will never get resolved).
|
|
|
|
//
|
|
|
|
// This is compound with the fact that we can't have a reliable delta API on the file system so we need to check all the timestamps
|
|
|
|
// every time and rely on this exclusively to know about changes.
|
|
|
|
//
|
|
|
|
// This explains occasional failures of the fuzzing program (it finds that the clients end up with two different notes after sync). To
|
|
|
|
// check that it is indeed the problem, check log-database.txt of both clients, search for the note ID, and most likely both notes
|
|
|
|
// will have been modified at the same exact second at some point. If not, it's another bug that needs to be investigated.
