Ignore empty directory file #6

Closed tobihagemann closed 7 years ago

tobihagemann commented 7 years ago

Related to https://github.com/cryptomator/cryptofs/issues/8.

Expected

Contents of a directory should be shown even if there is an empty directory file. So it should be just ignored.

Actual

Contents of a directory aren't shown if there is an empty directory file inside.

Hm okay, maybe it's wrong in this repository. Maybe it should just be silently ignored in CryptoFS. I have no clue. :smile:

Doesn't this issue belong into the https://github.com/cryptomator/cryptofs repo?

In my opinion we should definetely ignore empty directory files, as well as missing directories. What still is strange is that empty directory files seem to be "common". Not sure why that happens - checked the code and it looks good - maybe we should peer review the code in question again.
