StoragesService::getStorages() will check the visibility of the backend
and auth mechanism for the storage, and if either are not visible to the
user (aka disabled by admin) then the storage will be filtered out. The
original method StoragesService::getAllStorages() still exists in case
such storages need to be detected, but its use is discouraged.
VisibilityTrait -> PermissionsTrait
PermissionsTrait stores two sets of data, $permissions and
$allowedPermissions (analogous to $visibility and $allowedVisibility of
VisibilityTrait). Each set is a map of user type ('admin' or 'personal')
to permissions (mounting permission, create permission).
The result is that a backend can now be restricted for creation, while
still allowing it to be mounted. This is useful for deprecating backends
or auth mechanisms, preventing new storages being created, while still
allowing existing storages to be mounted.
Loading custom JS on a per-backend basis added needless complexity and
made dealing with async required. Now all backends/auth mechanisms load
custom JS in PHP
A backend can now specify generic authentication schemes that it
supports, instead of specifying the parameters for its authentication
method directly. This allows multiple authentication mechanisms to be
implemented for a single scheme, providing altered functionality.
This commit introduces the backend framework for this feature, and so at
this point the UI will be broken as the frontend does not specify the
required information.
Terminology:
- authentication scheme
Parameter interface for the authentication method. A backend
supporting the 'password' scheme accepts two parameters, 'user' and
'password'.
- authentication mechanism
Specific mechanism implementing a scheme. Basic mechanisms may
forward configuration options directly to the backend, more advanced
ones may lookup parameters or retrieve them from the session
New dropdown selector for external storage configurations to select the
authentication mechanism to be used.
Authentication mechanisms can have visibilities, just like backends.
The API was extended too to make it easier to add/remove visibilities.
In addition, the concept of 'allowed visibility' has been introduced, so
a backend/auth mechanism can force a maximum visibility level (e.g.
Local storage type) that cannot be overridden by configuration in the
web UI.
An authentication mechanism is a fully instantiated implementation. This
allows an implementation to have dependencies injected into it, e.g. an
\OCP\IDB for database operations.
When a StorageConfig is being prepared for mounting, the authentication
mechanism implementation has manipulateStorage() called,
which inserts the relevant authentication method options into the
storage ready for mounting.
Backends are registered to the BackendService through new data
structures:
Backends are concrete classes, deriving from
\OCA\Files_External\Lib\Backend\Backend. During construction, the
various configuration parameters of the Backend can be set, in a design
similar to Symfony Console.
DefinitionParameter stores a parameter configuration for an external
storage: name of parameter, human-readable name, type of parameter
(text, password, hidden, checkbox), flags (optional or not).
Storages in the StoragesController now get their parameters validated
server-side (fixes a TODO).
When reading in old mount.json files, they do not contain config ids.
Since these are needed to be able to use the UI and the new service
classes, these will be generated automatically.
The config grouping is based on a config hash.
