Android: Conflict promt on Auto Upload with "Overwrite remote version" checked

[jeroen7s]

Steps to reproduce

1. Add a folder to auto upload (the Whatsapp folder in my case)
2. Set the option "Overwrite remote version" on file conflicts
3. replace file in that folder with new version

Expected behaviour

Nextcloud should automatically overwrite the old file with the new one

Actual behaviour

Nextcloud gives a notification for a File Conflict
After clicking on a notification I have to manually resolve the conflict

Environment data

Android version: Android 10 / MIUI12 and Android9 / LineageOS16.0

Device model: (POCO F2 Pro) and (Oneplus 3T)

Stock or customized system: Stock and Customized

Nextcloud app version: 3.13.1 RC1 / 1.13.1

I can confirm this! I think it started happening two updates ago...

[computersalat]

same here...since update to 3.13.0 I am even not able to resolve conflict manually

Device: OnePlus6
Android: 10
Oxygen OS: 10.3.5

Failed uploads are piling up. If anyone has a workaround in the meantime please share !

[tobiasKaminsky]

This should be fixed with 3.13.1 RC1. You can try it via Google Play Beta version.
Stable 3.13.1 is planned for tomorrow.

[jeroen7s]

I don't think this is accurate as I definitely have this issue on 3.13.1 RC1

[tobiasKaminsky]

Is this also happening for new files?
Can you try to set the resolve strategy on this folder to something else, save, then set it back to overwrite?

[bestouff]

For me it happens for new files, and doing your manipulations doesn't change the behavior.

[smb500]

This error still exists with new files, as I posted here: https://github.com/nextcloud/android/issues/6963
Sorry, I didn't saw this thread here..

[Nodeswitch]

Can confirm this is happening with new files.

Running 20200908 from F-Droid.

[jeroen7s]

Seems to be fixed for me after manually cancelling all pending conflicts (manually resolving wouldn't work, as they would re-appear as a conflict for some reason)

[smb500]

Sorry, not for me. I can (manually resolve and then) cancel all pending conflicts, but next day this error (that the resolved conflicts won't be cleared) is coming again with other files.

[neurer]

Manually resolved conflict. Manually cancelled pending operations. Re-added the directory. "File upload conflict" persists with 3.13.1 RC1 from F-Droid.

[computersalat]

logcat_09-28-2020_11-15-16.txt

The latest Versions of this app became ... sorry ... a complete mess.
3.13.1 is showing autoupload conflicts that need to be handled manually. But even after manually resolving the conflicting file is shown as conflict ... the conflicting file is getting uploaded but still shown as conflicting file ... not good.
Instead of solving that issue you make it worse ...
with 3.13.0 you able to solve the conflict manually ... the file got uploaded and the conflict was solved.

I needed to re-add an account and reconfigure the whole autoupload again, cause there is nowhere an option to export or import the settings ... great job :+1:
Now after having all that configured again the app is now trying to sync ALL files of the configured folder (in the past this used to be only new files being added to the folders) ...

• why am I not asked if I want to sync ALL or just new files coming ?
• why is the app so dumb and trying to upload everything instead of syncing ?
  ... ending up not being able to use the app cause of continously crashing and only showing black screen and showing the message nexcloud is not responding ...

From my point of view sync means:

• check if the file exists before uploading
  not
• uploading and then showing conflict that file exists

[neurer]

Disabled sync for the specific folder. Updated from 3.13.1 RC1 to 3.13.1 via F-Droid -- changelog mentions "fix conflict handling on auto upload". Re-Enabled sync for the specific folder. Haven't had a single file upload conflict in the last three days.

[computersalat]

sync the WhatsApp database folder and you will have a conflict every morning cause of newly created msgstore.db.crypt12

[tobiasKaminsky]

sync the WhatsApp database folder and you will have a conflict every morning cause of newly created msgstore.db.crypt12

I cannot verify this.
I tried this

• set up screenshot folder with "overwrite"
• take a screenshot -> uploads directly
• edit this screenshot
• save -> uploads & overwrites

@computersalat are your settings correct?

@neurer says that it is working, or?

[neurer]

@neurer says that it is working, or?

Correct. Everything is in sync as of now and file upload conflict hasn't appeared ever since.

[bestouff]

Strange. I have 3.13.1 from F-Droid and still the same sync troubles.

[tobiasKaminsky]

Can you provide us additional infos via logcat? https://github.com/nextcloud/android/blob/master/README.md#getting-debug-info-via-logcat

Maybe this helps?

[tobiasKaminsky]

Hm. I added debug output which should be outputted when instant upload is running.
Have you added new files to all of those auto upload folders and gave me the entire logcat?
It must include "AutoUpload" and "Absolute path"…

[bestouff]

I don't really understand your question.
I'm using my phone regularly, especially the "DCIM" and "Call Recorder" folders get new files. The files do get uploaded to my server, but the conflict notifications continue to pile up.
What must include "AutoUpload" and "Absolute path" ? My settings ? The logcat command ? Something else ?

[tobiasKaminsky]

What must include "AutoUpload" and "Absolute path" ?

I gave you a custom APK, or?
And logcat creates a text file, in this there must be above strings, then I can have a better understanding of what is going on.

[bestouff]

I'm sorry I must have missed something. Where is that custom APK ?

[tobiasKaminsky]

Ah, I mixed something up.
Let me have soon a more detailed look into it.
