TaskBucket’s saveAndExtend() is now accomplished through extendTimeout() with an option to save parameters. SaveAndExtendIncrementally() has been removed as it is no longer needed because TaskBucket’s normal execution loop calls extendTimeout() periodically as long as the TaskFunc’s execute() actor has not finished or thrown. If a TaskFunc wants to save changes to task parameters to checkpoint progress for task restarts to benefit from it can call extendTimeout() explicitly with the updateParams flag set to true.

TaskBucket’s TaskFunc interface now has an optional handleError() which is called on any task that throws an error from execute() or finish(). Restore and Backup tasks use this to ensure that any errors that occur are placed in the backup or restore config’s lastError property. Bug fixes in log and range file encodings.

IBackupContainer has been rewritten to be a logical interface for storing, reading, deleting, expiring, and querying backup data. The details of how the data is organized or stored is now hidden from users of the interface. Both the local and blobstore containers have been rewritten, the key changes being a multi level directory structure and no more use of temporary files or pseudo-symlinks in the blob store implementation. This refactor has a large impact radius as the previous backup container was just a thin wrapper that presented a single level list of files and offered no methods for managing or interpreting the file structure so all of that logic was spread around other places in the code base. This made moving to the new blob store schema very messy, and without this refactor further changes in the future would only be worse.

Several backup tasks have been cleaned up / simplified because they no longer need to manage the ‘raw’ structure of the backup. The addition of IBackupFile and its finish() method simplified the log and range writer tasks. Updated BlobStoreEndpoint to support now-required bucket creation and bucket listing prefix/delimiter options for finding common prefixes. Added KeyBackedSet<T> type. Moved JSONDoc to its own header. Added platform::findFilesRecursively().
Still to do: update command line tool to use new IBackupContainer interface, fix bugs in Restore startup.

TaskBucket now logs a trace event for any task execution failures. Previously only external timeouts were logged, but now timeouts or any other error from inside the task is logged as well.
