All reloadCallback must return either true for success or false in case
of failure / non-existing folder.
Some file lists only have a root folder (favorite, shares), so restrict
the path to that to avoid having a wrong path in the breadcrumbs.
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
Failure to prepare the storage during backend or auth mechanism
manipulation will throw an InsufficientDataForMeaningfulAnswerException,
which is propagated to StorageNotAvailableException in the filesystem
layer via the FailedStorage helper class.
When a storage is unavailable not due to failure, but due to
insufficient data being available, a special 'indeterminate' status is
returned to the configuration UI.
Prior to this, the storage class name was stored in mount.json under the
"class" parameter, and the auth mechanism class name under the
"authMechanism" parameter. This decouples the class name from the
identifier used to retrieve the backend or auth mechanism.
Now, backends/auth mechanisms have a unique identifier, which is saved in
the "backend" or "authMechanism" parameter in mount.json respectively.
An identifier is considered unique for the object it references, but the
underlying class may change (e.g. files_external gets pulled into core
and namespaces are modified).
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.
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
Add support for external files accessed via SFTP using public key exchange authentication.
Keys are generated automatically when the configuration is added, or can be regenerated on demand if a key is compromised.
Creation of a new configuration row now triggers focus on that row. This is used to trigger auto-configuration for SFTP keys.
Generated public keys are saved in user's data directory for easy retrieval by an external application.
Add controller for SFTP key generation AJAX
SFTP class initialisation no longer produces a warning if the password field is missing.
Add unit tests for SFTP with key authentication backend
