Changes from 2.2.0 to 2.3.0

  • [API change] In order to allow to compile with both C-Blosc and C-Blosc2 libraries, a new API has been created for the symbols and function names that had collisions. Here are the changed symbols and functions:

    • Blosc2 symbols that take different values than in Blosc1:

      • BLOSC_VERSION_MAJOR -> BLOSC2_VERSION_MAJOR
      • BLOSC_VERSION_MINOR -> BLOSC2_VERSION_MINOR
      • BLOSC_VERSION_RELEASE -> BLOSC2_VERSION_RELEASE
      • BLOSC_VERSION_STRING -> BLOSC2_VERSION_STRING
      • BLOSC_VERSION_DATE -> BLOSC2_VERSION_DATE
      • BLOSC_MAX_OVERHEAD -> BLOSC2_MAX_OVERHEAD
      • BLOSC_MAX_BUFFERSIZE -> BLOSC2_MAX_BUFFERSIZE

    • Original Blosc1 API that takes the blosc1_ prefix:

      • blosc_compress -> blosc1_compress
      • blosc_decompress -> blosc1_decompress
      • blosc_getitem -> blosc1_getitem
      • blosc_get_compressor -> blosc1_get_compressor
      • blosc_set_compressor -> blosc_set_compressor
      • blosc_cbuffer_sizes -> blosc1_cbuffer_sizes
      • blosc_cbuffer_validate -> blosc1_cbuffer_validate
      • blosc_cbuffer_metainfo -> blosc1_cbuffer_metainfo
      • blosc_get_blocksize -> blosc1_get_blocksize
      • blosc_set_blocksize -> blosc1_set_blocksize
      • blosc_set_splitmode -> blosc1_set_splitmode

    • API that has been migrated to blosc2_ prefix

      • blosc_init -> blosc2_init
      • blosc_destroy -> blosc2_destroy
      • blosc_free_resources -> blosc2_free_resources
      • blosc_get_nthreads -> blosc2_get_nthreads
      • blosc_set_nthreads -> blosc2_set_nthreads
      • blosc_compcode_to_compname -> blosc2_compcode_to_compname
      • blosc_compname_to_compcode -> blosc2_compname_to_compcode
      • blosc_list_compressors -> blosc2_list_compressors
      • blosc_get_version_string -> blosc2_get_version_string
      • blosc_get_complib_info -> blosc2_get_complib_info
      • blosc_cbuffer_versions -> blosc2_cbuffer_versions
      • blosc_cbuffer_complib -> blosc2_cbuffer_complib

    It is recommended to migrate to the new API as soon as possible. In the meanwhile, you can still compile with the previous API (corresponding to C-Blosc2 pre-2.3.0), by defining the BLOSC1_COMPAT symbol in your C-Blosc2 app (before including the 'blosc2.h' header).

  • Fixed some issues in converting from super-chunks to frames and back. Now it is possible to do a rountrip without (known) problems.

  • LZ4 codec has been bumped to 1.9.4.
