In this article, we show that TSFS transactions go beyond preserving file-level integrity, and can also be used to enforce coherence across multiple files and directories. To support the discussion, we present a real-life application example and demonstrate how a single additional call to tsfs_commit() is all that is needed to make the code immune to unexpected failures.

In this second article in this series we see how an application can be designed to withstand such unforeseen events, using TSFS transactions. Doing so, we introduce the tsfs_commit() API. We also discuss the write transaction atomicity property, by which applications can be safely designed ignoring potential partial update issues.

This is the first article of a three-part series on fail-safe, storage-related application design using an embedded file system. The first part of the series lays out the fundamental problem of unexpected failures and briefly discusses partial solutions. The second part introduces how a fail-safe transactional file system such as the TREEspan File System (TSFS)

Last week was one of pride and excitement for the JBLopen’s development team as we released our latest product, the TREEspan File System (TSFS). After the official announcement and presentation, we feel the need to introduce the newcomer in a more personal way, such as we see it from the inside. Above all, we would
