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
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.
When we modified the code in revision
68ffd86594 (pull request #4018) to
consider collections of IListResultFilesets instead of DateTimes, we
neglected to preserve the backup times in the logs.
This fixes#4109.
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.
Since we are keeping around a reference to the IndexVolumeWriter and
BlockVolumeWriter instances, we cannot wrap their usages in using
statements.
This fixes issue #4046.
The LocalDatabase class was deleting from the BlocklistHash table based on the volume id of blocks. The deletes for the Blockset and BlocksetEntry tables were using a union query which included the same query the BlocklistHash delete was using. Changed the BlocklistHash delete query to use the union as well to ensure that all three tables would use the same query to delete the necessary rows. This fixes the "Detected non-empty blocksets with no associated blocks!" error.
Moved a write call in the DataBlockProcessor to send a volume for upload after setting blockvolume to null. This prevents a null reference exception because otherwise it would be sent to the SpillCollector and it tries to add a block, but the volume has already been closed.
Added the ? operator to the RegistryUtility class to prevent a null reference exception while debugging. It was annoying catching it in the debugger.
Fixes#4037
The ID in the Fileset table is the auto-incremented integer. When
considering filesets for deletion (in particular, when deleting specific
versions), we need to reference the backup version number that is
exposed to the user (integers where the newest backup version is 0).
This extracts the logic for various fileset deletion strategies into
separate classes. This simplifies the code and makes it easier to test
the individual functionalities.
If the most recent backups were partials (and not followed by a full
backup), they should not be removed. A partial backup should only be
removed if it is followed by a full backup.
This concerns issue #3982.
We declare this to be a partial backup, with the presumption being that
a synthetic filelist is only created when a backup is interrupted.
This concerns issue #3982.
