Moving files causes re-download and lost of shares with new chunking algorithmn

[kahlertl]

If you move a directory with a file manager on the client side, the moved files should not be re-downloaded and shares should be preserved - like in client v2.2.4. This issue is already known (owncloud/client#5670) and fixed in owncloud (owncloud/core#27508).

My current work around is to disable the new chunking algorithmn in the client with the env var OWNCLOUD_CHUNKING_NG=0 - as suggested here.

Steps to reproduce

1. Create test directory with two subdirectories shared and nested together with some dummy files
2. Share one shared subdirectory with some other user
3. Move shared subdirectory into nested on the client side (Ctrl+X or drag'N'drop in nautilus)

Expected behaviour

If you move a directory with a file manager on the client side, the moved files should not be re-downloaded and shares should be preserved - like in client v2.2.4.

Actual behaviour

After "moved to" event is propagated to the server, the client downloads the moved files from the server. The notification messages says "files ... updated". If the folder is a share or contains shares these shares are lost.

Are you using external storage, if yes which one: local

Are you using encryption: no

Are you using an external user-backend, if yes which one: LDAP

I tested this and it is fixed with #4524

Very nice 😃

@f3anaro How would I do this? Changing the owncloud.cfg file?

Done.

@travisbotello It is an environment variable -- you have to set it in your operating system.
