libpressio version 0.5.0

libpressio version 0.5.0

Major Features

• Implemented a framework to collect metrics about a compressor
• Implemented metrics plugins for compression ratios and bandwidths.
• Reorganized headers to make it clear which headers exported C++
  symbols, and which plugins implement compressors vs metrics

libpressio version 0.4.0

libpressio version 0.4.0

• Major Features
  • Bulk rename from liblossy -> libpressio to indicate that the library
    will eventually adopt lossless compression plugins
  • Support the ability to provide a type but not a value in
    pressio_option structures to allow more clear specification of the
    expected types for plugins
• Minor Features
  • Adopt optional types for the sz and zfp plugins
  • Moved more functions to the pressio_option structure to reduce
    duplicate functionality.

liblossy version 0.3.0

liblossy version 0.3.0

Major Changes

• Added functions to work with lossy_option structures with different
  types. Added similar convenience functions to lossy_options.
• Casting functions allow three levels of casting implicit, explicit,
  and special function casting.

Minor Changes

• Refactored type generic code to macros. Macros were used instead of
  templates to preserve a C-compatible interface.

liblossy version 0.2.0

liblossy version 0.2.0

Major Features

• Introduced a ZFP plugin
• Introduced owning lossy_data structures to better manage memory given
  to or from the library. Removed lossy_data_new in favor of these
  functions.
• More refined semantics for lossy_compressor_{get,set}_options
• New lossy_compressor_check_options function to verify usage
• New lossy_options_merge function to ease combining lossy_options
  structures
• liblossy_plugin now uses set_error(int, std::string const&) to set
  both the error code and message at the same time. Implementing plugins
  are recommended to create private functions that call this function to
  set error conditions.

Minor Features

• Updated Examples
• Improved Documentation
• Reduced internal code duplication

0.0.1: liblossy verison 0.1.0

liblossy verison 0.1.0

Major Features:

• C compatible API
• A generic way to set options for lossy compressors
• A generic way to represent data of different types
• A generic way to run different lossy decompressors and compressors
• A plugin system to easily extend the library with other compressors
• An implementation for a liblossy for the SZ error bounded lossy compressor
