This PR adds a flag to the test method so we can choose to test for read-only access (needed for restore) or read-write (needed for backups).
Additionally, this PR fixes a logic bug in that the BackendSourceProvider would not actually test the connection, but just check the placeholder element returned (which is always returned). With this PR the backend's ListAsync command is tested fully.
Also renamed the methods on ISourceProvider to have the `...Async` prefix.
This replaces #6939
This PR adds support for using Box, Dropbox, GoogleDrive, SharepointV2, MicrosoftGroups, and OneDrive as remote sources.
For GoogleDrive, this requires full permissions and not just the regular OAuth access token.
Also extended S3 and SMB to actually look up a file if requested, which makes it possible to rely on the backup exclusion files, even when using remote sources. (SSH/SFTP does not currently support this).
This PR updates existing backends to implement the `IRenameEnabledBackend` interface, allowing for more efficient file renaming operations. The implementation varies by backend, with some using native rename operations and others falling back to copy-and-delete patterns.
This PR adds a dynamic property so a backend can signal if it supports streaming, based on the settings.
This is currently used for the File backend, so that toggling `--use-move-for-put` will disable streaming on the backend instead of relying on the `--disable-streaming-transfers` flag.
This PR removes the `OAuthContextSettings` class, and makes the `--oauth-url` option available on each backend that uses it, so it can be configured as part of the destination.
To assemble everything related to configuring OAuth, the code was moved to the `AuthIdOptionsHelper`, such that the usage can be shared between implementations.
This PR also adds the option to set the default OAuth url from the environment variable `DUPLICATI_OAUTH_SERVICE`.
The server can then be set in the following locations (most important last):
- Environment variable
- Server-wide advanced settings
- Backup job advanced settings (or commandline)
- Destination url
This PR moves the check from the FTP backend into shared code, so all backends will now check for read/write permissions when using the "Test" button.
For situations where write permissions are not required (like restore or verify) there is a flag on the v2 API that indicates if the connection was established, so the UI can show a message suggesting that it is possible to proceed, if the current UI operation does not require write permissions.
This fixes#2473
When an error is thrown from box.com, it is sometimes not formatted according to the API documentation (most likely html/xml output).
This commit handles an invalid JSON response and returns the body contents in the error message.
This fixes#4283
This PR is the final change, where all backends are now purely implemented with async interfaces.
The code changes here replace the LIST call with an async version. This affect all backends (and then some) but the changes are mostly mechanical rewrites of the code.
In many places, the backeds were already prepared for async output, in other some glue was needed.
To reduce the scope of this change, some backends simply report a synchronous result as an async list.
Without await, the using statement can dispose the Stream before the
call to PutAsync completes, resulting in an ObjectDisposedException.
This fixes#4556.
The previous implementations resulted in an overload being hidden by one
without a default parameter, making it unclear which method was being
called. For example, consider the following signatures:
public MultipartItem(string content, string contenttype = null, string name = null, string filename = null)
public MultipartItem(string contenttype, string name = null, string filename = null)
