Implement support for deny ACLs #1798

glpatcern · 2021-06-16T12:45:45Z

This is still work in progress, but we thought to expose it earlier to gather feedback. Fixes #1792.

The important aspect especially for ownCloud is that now an empty permission set (equivalent to '' in WebDAV terms, and 0 for the integer representation) is considered valid. So the introduced change does not break the existing APIs but does represent a breaking change from a semantic point of view.

EDIT: to avoid breaking any existing assumption, the denial permission gets for now a different bit, PermissionNone. PermissionInvalid is still defined as 0.

@glpatcern @gmgigi96 I'm looking for a better alternative for GetOwners.
This new method sets a new dependency with the gateway service that was not there before.
With this change the storage providers needs to know where the gateway service is to query group information.
This means to also add this configuration change to our deployment in every storage provider.
We can do better.

While I'm looking how to add this logic into gateway layer reusing the permission set from the FileInfo and pass it down from the gateway to the storage provider you can replicate this PR against https://github.com/cernbox/reva@qa so we can merge it there and deploy it in our QA infra.

EDIT: just did cernbox#3
I'll merge it, but please do a quick review (nothing changes compared to this one)
