continuation of #1846 and #1584

rebased and fixed mocks
prototype share manager changes as described in make share manager single source of truth #2001
check if the deleted webdav / ocm code is breaking things ... and what it was supposed to handle

Thanks for opening this pull request! The maintainers of this repository would appreciate it if you would create a changelog item based on your changes.

Following our discussion these are the remaining tasks to implement:

Change the ocs API to check for and handle collisions with already existing shares or other nodes on the storage when accepting shares (@butonic, @refs)
Extend the sharesstorageprovider to consider all shares pointing to the mountpoint in question, e.g. when renaming or deleting (declining) a share (@butonic, @refs)
Make the sql share manager completely hide the fact that accepted group shares can be represented as child shares in the database (@aduffeck)

We also concluded that spaces support will not be implemented as part of this PR.

2b9adac (#2023) should address points 1 and 2 from the last comment.

There is however a tradeoff that we made. When there are 2 shares to the same resource, one is a group share and the other a user share, the group share is excluded from the results, so there are not 2 folders to the same location, this is as we discussed.

However, when listing all shares (in the sahred with me tab) we should list both received shares, as the user might want to decline them (i.e update the share state). This is currently not possible since listing the shares (by navigating to /Shares/) uses the same endpoint as the shared with me endpoint, and there is no filtering options to hide shares which point to the same resource.

@aduffeck could you udate the todo list with a checkmark for both tasks? I for some reason am not able to do so :(

@refs I'm not really following the problem with the same endpoint being used in /Shares and the shared-with-me endpoint. /Shares uses the sharesstorageprovider which talks to the share manager directly and can - and in fact does - merge the two shares to the same resource together, no?

@aduffeck What I meant is when we list shares on "Shared with me":

I think it would be better if we list all of the shares, group and user shares alongside, even if the mount point is the same. And I'm comparing it to this view:

navigating to /Shares from the web ui actually renders the mount point, but here we should hide the group share (based in: user shares are more explicit, and just hide the less explicit shares, totally my choice, we can decide on this).

The issue comes that these 2 different pages use the same endpoint, and there are currently no filters in the CS3APIS to capture this behavior. What I want is to use the same endpoint and fetch different results depending on where the request was made. Maybe I'm missing an essential part elsewhere 🤷

The #2215 (comment) created a really ugly merge conflict: the findEmbeddedMounts() introduced in this PR solves the problem #2215 adresses in a different way. We are going to prepare tests for 'virtual views' and then make sure this PR does not break them.

@ishank011 there are several places in the gateway that have special "webdav" handling ... what for? AFAICT it is related to OCM. Unfortunately, there are no tests covering that right now. Well the oc10 core testsuite does cover federated sharing, but the drone ci does not set up a second instance ...

While there are ways forward to cover OCM let's start with what these webdav handling is meant to do? Could you enlighten us?

@butonic yep, the OCM share targets are saved as webdav://$token@$idp?name=$path. When OCM shares are accepted, the references have these targets instead of cs3 for other shares.
When checkRef is called and it detects that the reference is of type 'webdav', the requests are then forwarded to the methods in the webdavstorageprovider.go file, and they actually make the webdav calls to the idp of the share creator.

phew ... do you have an example setup with two reva instances that I can use to set up a test environment?

@ishank ... um $path? so the references will break when the path changes? Why are we not using ids? Is OCM necessary for your current deployment?

IMO the share storage provider will return a cs3 reference which resolves to a yet to be implemented OCM storage provider. That can encapsulate the token and idp data necessary to access the remote instance.

I am currently looking at the /examples/ocmd setup. AFAICT it is deployed next to an existing reva deployment ... is it only starts the ocmd service on the http port ... so normal webdav is not available without an additional reva deployment.

I started a PR to clean up the toml configs and add an ocm config set in #2239
