Since the core changes in the cancelation process where now cancellationTokens are observed rather than a thread.abort attempt, the expected exception is now OperationCanceledException when calling .Abort on the controller.
Also eliminated the time based awaiting to abort in favor of monitoring the backup phase to ensure the .Abort happens after the controller has had time to initiate the backend and backend is at Backup_ProcessingFiles state.
This adds a test with a failed upload.
The failed upload is done in parallel, so (at least) one of the uploads succeeeds and one upload fails.
The backup then errors, but a subsequent backup continues without errors and creates a synthetic filelist.
Also refactored the DeterministicErrorBackend to not use magic strings.
And made it actually deterministic.
* Two small test fixes
* Ignore exceptions when comitting an empty transaction
* Attempt to fix FTP connection issue
* Unified test by having a single download function.
Added DNS probing call to attempt fixing sporadic DNS errors.
* Fixed argument order
* Avoid creating temp file during tests, if not needed
* 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
Replace `VerifyDir` and `CompareFiles` with
`AssertDirectoryTreesAreEquivalent` and `AssertFilesAreEqual`.
Move `WriteFile` to `TestUtils`.
Add "Symlink" category to start.sh.
When a backup is interrupted it will now show as a partial backup in the list of backups on the restore files page.
Temporary filelist volumes are protected from deletion in several places. All but the RestoreHandler
only protect the most recent filelist. The RestoreHandler protects all temporary filelist volumes as the user
might be restoring from one that would be deleted.
Prevent the CoCoL BackendRequests channel is retired exception from appearing when the backup is stopped by checking
if the channel is retired before trying to add the FlushRequest to the channel. Any exceptions from the BackendUploader
task will still be thrown.
One of the first things UploadSyntheticFilelist does is throw an exception if the volume is not in the Uploaded state. Or if it is in the Uploaded state, the next check would prevent a synthetic filelist from being created if the volume was not in the Uploading or Temporary states.
Removed the check for the volume not being in the Uploaded state as the warning in the second check handles that case.
Removed the using statement as it would dispose of the FilesetVolumeWriter after passing it to the UploadChannel. The UploadChannel could not use it since it had been disposed.
Fixed the GetRemoteVolumeFromIDAsync taking a fileset id and matching it up against a volume id. Now it will use fileset id to get the volume that matches the fileset.
Change the StopNow disruption test to not use a synthetic file list. The test was written with it not working and therefore fails a check on the number of filesets after stopping a backup.
Bonus fix for a possible null exception in Dispose for VolumeWriterBase.
This test would have failed prior to the changes in revision 8ab64071f0
("Display correct backup type when using direct restore"). Prior to
revision 8ab64071f0, all filesets would have been marked as partial when
performing a direct restore without the local database.
This concerns issue #3982.
This test would have failed prior to the changes in revision 0cfce6be39
("Include fileset file when repairing missing dlist file").
This concerns issue #3982.
This test would have failed prior to the changes in revision 51b4ecfb28
("Include fileset file in dlist files after purge operation").
This concerns issue #3982.
