TODO check deny feature during the upgrade test between 5.0.0 and 7.0.0
put FRONTEND_OCS_ENABLE_DENIALS to deprecated envs
enable e2e test https://github.com/owncloud/web/blob/master/tests/e2e/cucumber/features/shares/denyShareAccess.feature

If this gets merged, I will do the needed translation on transifex for the new strings.

Note, if TX needs to be added quickly befor final releasing, one needs to initiate a manualy sync, I will do the TX and another sync needs to be done. Then all is up to date.

tested:

creating/changing/deleting share with role cannot access - works correct
user can see/change/delete cannot access share which was created in 5.0 version

remarks:

500 error when deleting deny share (was created in version 5.0) but looks like works -> user recipient can see resource
steps:
- switch ocis version 5
- admin creates folder and shares folder to Users group
- admin shares folder to einstein with denied role
- upgrade ocis to version 7
- admin deletes denied role

@micbar today I saw that you had similar issue and fixed it. it was case with project space - it works

no german translation

user can see activity of the denied resource
sse events in this case work correct but confuse users. If we deny access -> user gets notification that resource was shared but user doesn't see resource. If we delete cannot access - user see notification that share was deleted and user can see resource.
user can search by denied resource and cannot create resource with same name - existing bugs User doesn't get correct message if he creates resource with same of denied resource name web#9029 Denial of access to a resource. User can find denied resource #6288

Correct. That was a general issue with sharing and has been fixed in reva cs3org/reva#4968.

Needs a reva bump to arrive in ocis master.

@rhafer Not the "nicest" solution, I admit.

We have the contract with the clients that we

either set a value on roles

or set a value on @libre.graph.permissions.actions

That means, if we disable the role "RoleDenied" and have existing shares, we need to return at least a hint to the user.

Fine for me, if you want to solve it differently.

After discussion with @butonic and @kobergj we decided to return none in that case.

Important Info: We decided long ago, that we will only go with a "full denial", we do not intend to think about negative permissions in the future. So my assumption here is valid.

put FRONTEND_OCS_ENABLE_DENIALS to deprecated envs

Before merging, if the var has been deprecated, please run make -C docs docs-generate to add the changed env_vars.yaml to the PR. I need to do afterwards with a separate PR the changed envvar magic... 😅

Needs to be discussed with @kobergj

We deprecated the whole OCS Api with 5.0.0.

I would have removed it already but the clients were not able to move to the LibreGraph API in time.

butonic · 2024-11-25T08:38:30Z

7.0.0?
