Newly shared folder gets automatically synced

[yahesh]

Expected behaviour

When sharing a folder with a user, it should not be automatically synced by the sync client.

Actual behaviour

When a folder gets shared with a user then the sync client automatically starts syncing that folder. There seems to be a check so that huge folders don't get synced automatically. However, when the folder gets shared while it's still empty, the client assumes that it's okay to activate the syncing due to a minimal size. When that folder gets filled with files later on, the sync client sticks to its previous decision.

Steps to reproduce

1. Create an empty folder
2. Share the folder with another user
3. Wait until the sync client of that user has checked for new files on the server
4. Fill the newly shared (and accepted for sync) folder with data and look as the disk of that user fills up.

Work-arounds:

• If you set the 'ask for confirmation' setting to 0, you'll be asked for all folders with any data in them.
• our server will probably get a feature where you can enforce that you have to accept all shares before they become available

Otherwise, cool feature, thanks for doing a pull request, I hope we can find time to review it soon - sorry that that takes so long, we're a small team!

Leaving a reply here to get updates if this get's 'fixed'. Can do the above of course, but not really intuitive for non-tech users. When choosing to essentually sync everything, there should be a way to completely deselect the root folder and select individual folders, instead of having to manually add individual folders, or even a tick box that asks users if they would like to download a shared folder.

Looks like this issue can be closed now that the server has the feature implemented. See nextcloud/server#16828
