* Package name : libjio Version : 0.50 Upstream Author : Alberto Bertogli (albert...@blitiri.com.ar) * URL : http://blitiri.com.ar/p/libjio/ * License : Buena Onda License Agreement (v1.0) Programming Lang: C Description : library for journaled I/O To ensure reliability, some file systems and databases provide support for something known as journalling. The idea is to ensure data consistency by creating a log of actions to be taken (called a Write Ahead Log) before committing them to disk. That way, if a transaction were to fail due to a system crash or other unexpected event, the write ahead log could be used to finish writing the data. While this functionality is often available with networked databases, it can be a rather memory- and processor-intensive solution, even where reliable writes are important. In other cases, the filesystem does not provide native journalling support, so other tricks may be used to ensure data integrity, such as writing to a separate temporary file and then overwriting the file instead of modifying it in-place. Unfortunately, this method cannot handle threaded operations appropriately. Thankfully, Alberto Bertogli published a userspace C library called libjio that can provide these features in a small (less than 1500 lines of code) library with no external dependencies. -- _________________________ Ryan Niebur ryanrya...@gmail.com
