This ensures that files cannot appear on the remote destination, despite terminating the host program.
This fixes#4485
There is still work needed to handle the repair and compact operations so they use transactions and can commit changes during transfer progress.
This adds an extra option to allow setting the SQLite page cache size as a regular option.
Prior to this commit it was only possible to set the SQLite page cache size via environment variables.
The option to use environment variables is preserved, and as options from the environment variable are applied after the new setting, environment variables take precedence.
The default value for the new option is to use 1% of the system memory for the page cache. For the restore process, a connection per worker may be made which defaults to half the number of cores, so the maximum amount of memory is 1% * half the CPU cores.
This is just the upper limit, and SQLite may choose not to use all of it.
This fixes#6178
The code was using a two-way reference linking the database to the results and the results to the database.
However, this was not really used so it ended up just cluttering the code. With this commit, the results and databases are no longer keeping track of each other, and the only interaction is when the results are written to the database at the end of the operation.
To ensure result data is always written, this code has been moved into the controller, which will now flush the results for all operations. Prior to this, only some operations would write result data to the log.
The controller now also handles logic for cleaning old log data and invoking the vacuum command.
Fixed a bug due to using System.Text.Json where some attributes from NewtonSoft.Json were being applied and not picked up.
Rewrote all operation handlers to be async.
This moves the async/sync threshold out into the controller.
Fixed all the uses of cancellation token in the handlers to use the provided cancellation token.
Introduced a new ReusableTransaction that can be passed around, avoiding a ref parameter passing of the transaction instance.
If the user selects the blocksize to be the same as the remote volume size, this will cause each block to be in a separate volume and will trigger repeated compact calls.
This commit adds a check that ensures the volume size is large enough to hold at least two blocks.
Also fixed an issue where the compact could create volumes larger than the set limit (at most one block larger).
Backup will auto-repair, and user otherwise need to call "repair" to recover the state, before invoking compact/delete/purge.
This is done to prevent cases where the remote state contiains partial data and the automatic cleanup process would remove remote files.
This commit adds extra logic to prevent cases where the backup reports success but leaves behind partial files.
A new flag is recorded to track if partial files are possible. If no partial files are possible, the verification will fail if any are found.
* Rewrite the backend manager.
This creates a new more logic backend manager that handles all backend operations.
For each top-level operation, there is now a single backend manager instance that is passed to sub-commands.
The internals of the backend manager are now rewritten to use async logic instead of threading.
The design uses a single task runner that dispatches operations and honors concurrent settings and limits from one place.
The logic for each operation has been moved into a separate files/classes to make it easier to understand each operation.
This fixes#5804
* Fixed a few issues with not awaiting tasks
* Fixed not creating empty databases
* Fixed an issue with hashes not being recorded on download
* Reworked the download logic to avoid attempting to decrypt the file if it has been modified.
* Review fixes
* Renamed db collector to better reflect the purpose.
* Review fixes
* 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
The first optimization was to add guards around the queries in case the second collection is empty (which is was when the slow path was found).
The second optimization is to use a HashSet for the second collection, as this speeds up lookup, compared to using two List of string.
Before the dindex files are deleted on the remote, update the state in the database to Deleting. Previously, only dblock files were handled this way.

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.
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.
Previously, the indentation of the following code block gave the
impression that it was part of the foreach loop when in fact it would
only be executed once.
