* Workaround for multi-backend.
There is currently an issue with creating the BackendManager which has a backend instance. This instance is not used by the uploader, so they will create new instances.
The BackendManager instance can then time out, but is used later.
This commit will allow the uploader to "borrow" the instance from the backend manager, so only a single instance is needed.
This is not a clean fix, but doing so requires a full rewrite of the backend manager and uploader, so the controller creates a single instance of the manager, which is then used for all operations.
This would allow the backend manager to keep track of instances across all requests.
* Improved reuse after shutdown
* Fixed issues with timeout in msgraph
Fixed a place where the cancellation token was not applied.
Fixed a problem with msgraph not sending correct DNS information.
Fixed a problem with msgraph downloading the entire file before streaming it, bypassing throttle and tripping the timeout.
Added `ITimeoutExemptBackend` to selectively disable timeouts for backends that do not support it.
Updated the backendmanager to support `ITimeoutExemptBackend`.
Updated the backendmanager to abort as soon as a timeout happens.
* Updated BackendTester to use the `TimeoutObservingStream` and support the `--read-write-timeout` setting.
Updated backend tester code to use `var`
* Fixed a bug reading the `read-write-timeout`
* Updated to using constants with names instead of `-1`.
* Simplified task control by having all logic in a single class and using async control mechanism
* Fixed the tests
* Made the marking of a backup partial explicitly communicated if the enumeration process is stopped.
* Added support for pausing active transfers
* Introduced transfer token to abort operations.
* Updated the way LiveControl is emitting events.
* Retains the paused state of the server across reboots, this fixes#5760.
* Reworked the way throttle speeds are propagated through LiveControls.
* Added option to pause transfers in the UI.
* Removed throttle settings from the LiveControls class so it is exclusively handled by the ApplicationSettings.
* Removed `thread-priority` as it does not work at all when tasks are used.
* Fixed the stop dialog and API to only support stop and abort.
* Removed unused variables
Since a reference to the IndexVolumeWriter is passed to the
FileEntryItem, we should not dispose of it here.
This reverts commit b6123cc156.
This is a potential fix for issue #4130.
In code the throttling generally works backwards than what one would expect.
The streams that are throttled are the streams that operate on files from the local machine.
This fixes the download throttling not working and the upload throttling applying to
both uploads and downloads.
When doing a Put operation the stream on the local machine is reading from the
local filesystem and hence the upload throttle bytes per second needs to be
applied to the reading of the stream, not the writing.
Similarly when doing a Get operation the download throttle bytes per second needs
to be applied to the writing of the stream.
Fixes#4115
The list folder was not being written to dindex files when performing a
compact operation. After the data blocks have been moved to a new volume
and the new volume data is finished being written to the new index file,
read the blocklists from the database and write them to the new index
file.
The InnerException property of an AggregateException can be another
AggregateException. By calling Flatten(), we remove inner
AggregateExceptions so that the InnerExceptions property contains all
the original exceptions. The InnerException property is the first
element of InnerExceptions.
