## Abstract
|
||||
## Overview
|
||||
|
||||
This service provides an oCIS extension that wraps [reva](https://github.com/cs3org/reva/) and adds an opinionated configuration to it.
|
||||
The storage extension wraps [reva](https://github.com/cs3org/reva/) and adds an opinionated configuration to provide two core services for the oCIS platform:
|
||||
1. A [*Spaces Registry*]({{< ref "./spacesregistry.md" >}}) that acts as a dictionary for storage *Spaces* and their metadata
|
||||
2. A [*Spaces Provider*]({{< ref "./spacesprovider.md" >}}) that organizes *Resources* in storage *Spaces* and persists them in an underlying *Storage System*
|
||||
|
||||
## Architecture Overview
|
||||
*Clients* will use the *Spaces Registry* to poll or get notified about changes in all *Spaces* a user has access to. Every *Space* has a dedicated `/dav/spaces/<spaceid>` WebDAV endpoint that is served by a *Spaces Provider* which uses a specific reva storage driver to wrap an underlying *Storage System*.
|
||||
|
||||
The below diagram shows the oCIS services and the contained reva services within as dashed boxes. In general:
|
||||
1. A request comes in at the proxy and is authenticated using OIDC.
|
||||
2. It is forwarded to the oCIS frontend which handles ocs and ocdav requests by talking to the reva gateway using the CS3 API.
|
||||
3. The gateway acts as a facade to the actual CS3 services: storage providers, user providers, group providers and sharing providers.
|
||||
|
||||
{{< svg src="extensions/storage/static/overview.drawio.svg" >}}
|
||||
|
||||
The dashed lines in the diagram indicate requests that are made to authenticate requests or lookup the storage provider:
|
||||
1. After authenticating a request, the proxy may either use the CS3 `userprovider` or the accounts service to fetch the user information that will be minted into the `x-access-token`.
|
||||
2. The gateway will verify the JWT signature of the `x-access-token` or try to authenticate the request itself, e.g. using a public link token.
|
||||
|
||||
{{< hint warning >}}
|
||||
The bottom part is lighter because we will deprecate it in favor of using only the CS3 user and group providers after moving some account functionality into reva and glauth. The metadata storage is not registered in the reva gateway to seperate metadata necessary for running the service from data that is being served directly.

||||

|
||||
## Endpoints and references
|
||||
|
||||
In order to reason about the request flow, two aspects in the architecture need to be understood well:
|
||||
1. What kind of [*namespaces*]({{< ref "./namespaces.md" >}}) are presented at the different WebDAV and CS3 endpoints?
|
||||
2. What kind of [*resource*]({{< ref "./terminology.md#resources" >}}) [*references*]({{< ref "./terminology.md#references" >}}) are exposed or required: path or id based?

With the spaces concept we are planning to introduce a global namespace to the ownCloud webdav endpoints.

To release a new version of the storage submodule, you have to follow a few simple steps.
|
||||
|
||||
## Preparation
|
||||
|
||||
1. Before releasing, make sure that reva has been [updated to the desired version]({{< ref "updating" >}})
|
||||
|
||||
## Release
|
||||
1. Check out master
|
||||
{{< highlight txt >}}
|
||||
git checkout master
|
||||
git pull origin master
|
||||
{{< / highlight >}}
|
||||
2. Create a new tag (preferably signed) and replace the version number accordingly. Prefix the tag with the submodule `storage/v`.
|
||||
{{< highlight txt >}}
|
||||
git tag -s storage/vx.x.x -m "release vx.x.x"
|
||||
git push origin storage/vx.x.x
|
||||
{{< / highlight >}}
|
||||
5. Wait for CI and check that the GitHub release was published.
|
||||
|
||||
Congratulations, you just released the storage submodule!

|
||||
## Storage Spaces
|
||||
A storage *space* is a logical concept. It organizes a set of [*resources*]({{< ref "#resources" >}}) in a hierarchical tree. It has a single *owner* (*user* or *group*),
|
||||
a *quota*, *permissions* and is identified by a `storage space id`.
|
||||
|
||||
{{< svg src="extensions/storage/static/storagespace.drawio.svg" >}}
|
||||
|
||||
Examples would be every user's personal storage *space*, project storage *spaces* or group storage *spaces*. While they all serve different purposes and may or may not have workflows like anti virus scanning enabled, we need a way to identify and manage these subtrees in a generic way. By creating a dedicated concept for them this becomes easier and literally makes the codebase cleaner. A storage [*Spaces Registry*]({{< ref "./spacesregistry.md" >}}) then allows listing the capabilities of storage *spaces*, e.g. free space, quota, owner, syncable, root etag, upload workflow steps, ...
|
||||
|
||||
Finally, a logical `storage space id` is not tied to a specific [*spaces provider*]({{< ref "./spacesprovider.md" >}}). If the [*storage driver*]({{< ref "./storagedrivers.md" >}}) supports it, we can import existing files including their `file id`, which makes it possible to move storage *spaces* between [*spaces providers*]({{< ref "./spacesprovider.md" >}}) to implement storage classes, e.g. with or without archival, workflows, on SSDs or HDDs.
|
||||
|
||||
## Shares
|
||||
*To be clarified: we are aware that [*storage spaces*]({{< ref "#storage-spaces" >}}) may be too 'heavywheight' for ad hoc sharing with groups. That being said, there is no technical reason why group shares should not be treated like storage [*spaces*]({{< ref "#storage-spaces" >}}) that users can provision themselves. They would share the quota with the users home or personal storage [*space*]({{< ref "#storage-spaces" >}}) and the share initiator would be the sole owner. Technically, the mechanism of treating a share like a new storage [*space*]({{< ref "#storage-spaces" >}}) would be the same. This obviously also extends to user shares and even file individual shares that would be wrapped in a virtual collection. It would also become possible to share collections of arbitrary files in a single storage space, e.g. the ten best pictures from a large album.*

In oc10 we originally had `remote.php/webdav` which would render the current users home [*storage space*]({{< ref "./terminology.md#storage-spaces" >}}). The early versions (pre OC7) would jail all received shares into a `remote.php/webdav/shares` subfolder. The semantics for syncing such a folder are [not trivially predictable](https://github.com/owncloud/core/issues/5349), which is why we made shares [freely mountable](https://github.com/owncloud/core/pull/8026) anywhere in the users home.
|
||||
|
||||
The current reva implementation jails shares into a `remote.php/webdav/Shares` folder for performance reasons. Obviously, this brings back the [special semantics for syncing](https://github.com/owncloud/product/issues/7). In the future we will follow [a different solution](https://github.com/owncloud/product/issues/302) and jail the received shares into a dedicated `/shares` space, on the same level as `/home` and `/spaces`. We will add a dedicated [API to list all *storage spaces*](https://github.com/owncloud/ocis/pull/1827) a user has access to and where they are mounted in the users *namespace*.

To ensure that all resources under that [*namespace*]({{< ref "./terminology.md#namespaces" >}}) are scoped to the user the URL would have to include the principal like `remote.php/dav/spaces/<username>`, a precondition for e.g. WebDAV [RFC5397](https://tools.ietf.org/html/rfc5397).

### User and Group provisioning

In oc10 users are identified by a username, which cannot change, because it is used as a foreign key in several tables. For oCIS we are internally identifying users by a UUID, while using the username in the WebDAV and OCS APIs for backwards compatability. To distinguish this in the URLs we are using `<username>` instead of `<userid>`. You may have encountered `<userlayout>`, which refers to a template that can be configured to build several path segments by filling in user properties, e.g. the first character of the username (`{{substr 0 1 .Username}}/{{.Username}}`), the identity provider (`{{.Id.Idp}}/{{.Username}}`) or the email (`{{.Mail}}`)

## Storage commands
|

A *storage driver* implements access to a [*storage system*]({{< ref "#storage-systems" >}}):
|
||||
|
||||
`storage` has multiple storage provider commands to preconfigure different default configurations for the reva *storage provider* service. While you could rerun `storage storage-oc` multiple times with different flags to get multiple instances we are giving the different commands the necessary default configuration to allow the `ocis` binary to simply start them and not deal with configuration.
|
||||
It maps the *path* and *id* based CS3 *references* to an appropriate [*storage system*]({{< ref "#storage-systems" >}}) specific reference, e.g.:
|
||||
- eos file ids
|
||||
- posix inodes or paths

- deconstructed filesystem nodes

A [*CS3 reference*](https://cs3org.github.io/cs3apis/#cs3.storage.provider.v1beta1.Reference) can carry a *path* and a [CS3 *resource id*](https://cs3org.github.io/cs3apis/#cs3.storage.provider.v1beta1.ResourceId). The references come in two flavors: absolute and combined.
|
||||
Absolute references have either the *path* or the *resource id* set:
|
||||
- An absolute *path* MUST start with a `/`. The *resource id* MUST be empty.
|
||||
@@ -28,59 +27,12 @@ Combined references have both, *path* and *resource id* set:
|
||||
- the *resource id* identifies the root [*resource*]({{< ref "#resources" >}})
|
||||
- the *path* is relative to that root. It MUST start with `.`
|
||||
|
||||
|
||||
### Storage Spaces
|
||||
A *storage space* organizes a set of [*resources*]({{< ref "#resources" >}}) in a hierarchical tree. It has a single *owner* (*user* or *group*),
|
||||
a *quota*, *permissions* and is identified by a `storage space id`.
|
||||
|
||||
{{< svg src="extensions/storage/static/storagespace.drawio.svg" >}}
|
||||
|
||||
Examples would be every user's personal storage space, project storage spaces or group storage spaces. While they all serve different purposes and may or may not have workflows like anti virus scanning enabled, we need a way to identify and manage these subtrees in a generic way. By creating a dedicated concept for them this becomes easier and literally makes the codebase cleaner. A [*storage space registry*]({{< ref "#storage-space-registries" >}}) then allows listing the capabilities of [*storage spaces*]({{< ref "#storage-spaces" >}}), e.g. free space, quota, owner, syncable, root etag, upload workflow steps, ...
|
||||
|
||||
Finally, a logical `storage space id` is not tied to a specific [*storage provider*]({{< ref "#storage-providers" >}}). If the [*storage driver*]({{< ref "#storage-drivers" >}}) supports it, we can import existing files including their `file id`, which makes it possible to move [*storage spaces*]({{< ref "#storage-spaces" >}}) between [*storage providers*]({{< ref "#storage-providers" >}}) to implement storage classes, e.g. with or without archival, workflows, on SSDs or HDDs.
|
||||
|
||||
### Shares
|
||||
*To be clarified: we are aware that [*storage spaces*]({{< ref "#storage-spaces" >}}) may be too 'heavywheight' for ad hoc sharing with groups. That being said, there is no technical reason why group shares should not be treated like [*storage spaces*]({{< ref "#storage-spaces" >}}) that users can provision themselves. They would share the quota with the users home [*storage space*]({{< ref "#storage-spaces" >}}) and the share initiator would be the sole owner. Technically, the mechanism of treating a share like a new [*storage space*]({{< ref "#storage-spaces" >}}) would be the same. This obviously also extends to user shares and even file indvidual shares that would be wrapped in a virtual collection. It would also become possible to share collections of arbitrary files in a single storage space, e.g. the ten best pictures from a large album.*
|
||||
|
||||
|
||||
### Storage Space Registries
|
||||
|
||||
A *storage space registry* manages the [*namespace*]({{< ref "./namespaces.md" >}}) for a *user*: it is used by *clients* to look up storage spaces a user has access to, the `/dav/spaces` endpoint to access it via WabDAV, and where the client should mount it in the users personal namespace.

## Technical concepts
|
||||
|
||||
### Storage Drivers
|
||||
|
||||
A *storage driver* implements access to a [*storage system*]({{< ref "#storage-systems" >}}):
|
||||
|
||||
It maps the *path* and *id* based CS3 *references* to an appropriate [*storage system*]({{< ref "#storage-systems" >}}) specific reference, e.g.:
|
||||
- eos file ids
|
||||
- posix inodes or paths
|
||||
- deconstructed filesystem nodes
|
||||
|
||||
### Storage Providers
|
||||
|
||||
A *storage provider* manages [*resources*]({{< ref "#resources" >}}) identified by a [*reference*]({{< ref "#references" >}})
|
||||
by accessing a [*storage system*]({{< ref "#storage-systems" >}}) with a [*storage driver*]({{< ref "#storage-drivers" >}}).
|
||||
|
||||
{{< svg src="extensions/storage/static/storageprovider.drawio.svg" >}}
|
||||
|
||||
### Storage Registry
|
||||
|
||||
A *storage registry* manages the [*CS3 global namespace*]({{< ref "./namespaces.md#cs3-global-namespaces" >}}):
|
||||
It is used by the *gateway*
|
||||
to look up `address` and `port` of the [*storage provider*]({{< ref "#storage-providers" >}})
|
||||
that should handle a [*reference*]({{< ref "#references" >}}).
|
||||
|
||||
{{< svg src="extensions/storage/static/storageregistry.drawio.svg" >}}
|
||||
|
||||
### Storage Systems
|
||||
Every *storage system* has different native capabilities like id and path based lookups, recursive change time propagation, permissions, trash, versions, archival and more.
|
||||
A [*storage provider*]({{< ref "#storage-providers" >}}) makes the storage system available in the CS3 API by wrapping the capabilities as good as possible using a [*storage driver*]({{< ref "#storage-drivers" >}}).
|
||||
There migt be multiple [*storage drivers*]({{< ref "#storage-drivers" >}}) for a *storage system*, implementing different tradeoffs to match varying requirements.

||||

|
||||

### Gateways
|
||||
A *gateway* acts as a facade to the storage related services. It authenticates and forwards API calls that are publicly accessible.

## Updating reva
|
||||
|
||||
1. Run `go get github.com/cs3org/reva@master` in all repos that depend on reva
|
||||
2. Create a changelog entry containing changes that were done in [reva](https://github.com/cs3org/reva/commits/master)
|
||||
3. Create a Pull Request to ocis master with those changes
|
||||
4. If test issues appear, you might need to adjust the tests
|
||||
5. After the PR is merged, consider doing a [release of the storage submodule]({{< ref "releasing" >}})

### User and Group provisioning
|
||||
|
||||
In oc10 users are identified by a username, which cannot change, because it is used as a foreign key in several tables. For oCIS we are internally identifying users by a UUID, while using the username in the WebDAV and OCS APIs for backwards compatability. To distinguish this in the URLs we are using `<username>` instead of `<userid>`. You may have encountered `<userlayout>`, which refers to a template that can be configured to build several path segments by filling in user properties, e.g. the first character of the username (`{{substr 0 1 .Username}}/{{.Username}}`), the identity provider (`{{.Id.Idp}}/{{.Username}}`) or the email (`{{.Mail}}`)
|
||||
|
||||
{{< hint warning >}}
|
||||
Make no mistake, the [OCS Provisioning API](https://doc.owncloud.com/server/developer_manual/core/apis/provisioning-api.html) uses `userid` while it actually is the username, because it is what you use to login.
|
||||
{{< /hint >}}
|
||||
|
||||
We are currently working on adding [user management through the CS3 API](https://github.com/owncloud/ocis/pull/1930) to handle user and group provisioning (and deprovisioning).
