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).
Added option to disable autoscan of external storages
Mount option file system scan is now an int
Move priority field to avoid undefined field in storage options
All input elements inside the storage options block get parsed into
storage options.
Moving the priority field outside prevents it to appear in the storage
config, as expected. It is still parsed by special code.
The mount options are now passed to the UI and stored in a hidden field.
The ext storage controllers and services also know how to load/save them
from the legacy config.
- Added StorageConfig class to replace ugly arrays
- Implemented StorageService and StorageController for Global and User
storages
- Async status checking for storages (from Xenopathic)
- Auto-generate id for external storage configs (not the same as
storage_id)
- Refactor JS classes for external storage settings, this mostly
moves/encapsulated existing global event handlers into the
MountConfigListView class.
- Added some JS unit tests for the external storage UI
remove minified select2 js
show avatars for users, simpler results
remove unneeded users and groups from settings template
fix css, escape user and group names
For external storage with lots of parameter settings (>4), wrap the content of the cell to let a full view of the parameters.
The rows of the table are now always visible until the end (the trash icon is accessible).
(Note : A strange 3px margin forces me to add a class on the row added by javascript, to be able to align them with the rows rendered by the server.)
Merging of configurations is whenever the same config is available for
multiple users/groups, in which case the config is considered as a
single one by the UI, and shows multiple users/groups selected.
Fixed merging logic to make sure that class, mount point and options are
the same before merging them.
Fixed merging to work correctly when the same mount point path is used
for separate users and configs. These are now correctly shows in the UI
as separate entries.
Existing code checks for the existence of a modifier ('&', '!', '#', '*')
anywhere in the field name, but strips the first character regardless. This
change makes it so that only modifiers at the beginning of the string are
counted.
