Files disappear when overwriting due to GD revisions

[mmattel]

Initial copy a file via oC to a GD mount.
Then change the content of the file by editing it on your local computer.
Re-upload the file, the name is the same.

What happens is, that the files gets deleted in oC, but is present in GD as actual and older revision.

When you delete the revisions in GD, refresh, the file appears and is synced again.

oC can´t manage multiple files with the same name, therefore they are "deleted".

It seems that the API access currently used is not managing revisions.

Background:
Mounting a GD
Syncing it with the client
Regular dropping existing content with updates into that mount.
As more changed files you have, as less files you see via oC 💥
But they are present as revsions in GD itself.

I digged a bit in the code.

There is a mechanism to check if filenames are present multiple times in a folder.
This mechanism can be improved to take only that file with the youngest date vs to reject all files having the same name. Then it would behave like a normal filesystem for oC.
