Notification: 'Read empty file' and crashes

[glocalglocal]

Every few minutes DecSyncCC generates this notification:
Read empty file: org.decsync.library.RealFileSys@b...

The message is truncated and I can't read the rest.

This has been happening for weeks. 2-3 days ago DecSyncCC also started stopping immediately every time I tap on its icon, but it seems to do the job in the background, updating the calendar as it did before (ie not very well, with lots of triplicates, ghost events of deleted entries etc (see my earlier issues that may help explain the notification and clashes).

I updated to v2.0.1 earlier today but there was no improvement on any front.

(Android 7)

I have the same issue. DecSyncCC 2.1.0 installed from F-Droid. I'm running LineageOS 18.1 (Android 11). Let me know if I can help with debugging somehow.

The notification issue started with 2.1.0 (not earlier), but the app has been unable to open for a longer time - so probably the two issues are separate. Here's my older issue about the crashing: #59

It means that there is an empty file, which should never occur (it should delete it instead), but apparently it can happen... If you are on LInux on the desktop you can easily find the empty file by executing find .local/share/decsync -empty. (The notification should give the path of the file, but there was a bug in it.) If it is a .decsync-sequence file you can safely remove it. The next update will ignore the empty files, meaning it won't crash anymore.

I searched through my Windows 10 files and found an empty info. I deleted it and DecSyncCC stopped crashing. Not sure if this is related but I recently updated radicale_storage_decsync as well and suddenly most of the many problems I had disappeared (several missing calendars appeared, duplicate/triplicate etc events are gone, syncing from the mobile to the PC works). Only thing remaining is the many syncthing conflicts (20-30 conflict files per day). The big test will be when I add another 2 devices to the current 3 devices (incl a Raspberry Pi). Many thanks.
