Motivation: Before this changes Bzip2BitReader and Bzip2BitWriter accessed to ByteBuf byte by byte. So tests for Bzip2 compression codec takes a lot of time if we ran them with paranoid level of resource leak detection. For more information see comments to #2681 and #2689. Modifications: - Increased size of bit buffers from 8 to 64 bits. - Improved reading and writing operations. - Save link to incoming ByteBuf inside Bzip2BitReader. - Added methods to check possible readable bits and bytes in Bzip2BitReader. - Updated Bzip2 classes to use new API of Bzip2BitReader. - Added new constants to Bzip2Constants. Result: Increased size of bit buffers and improved performance of Bzip2 compression codec (for general work by 13% and for tests with paranoid level of resource leak detection by 55%). |
