News for kodo-c

This file lists the major changes between versions. For a more detailed list of every change, see the Git log.

Latest

  • tbd

8.0.1

  • Patch: Disable the rlnc and fulcrum API when the corresponding repositories are not available.

8.0.0

  • Major: The kodo_ prefix was changed to kodoc_ in all functions, types and enums. The old prefix caused name collisions with symbols defined in the main kodo repositories.
  • Major: Replaced kodo_factory_new_encoder and kodo_factory_new_decoder with kodo_factory_build_coder.
  • Minor: Added the enable_codecs option to only enable specific codecs when configuring kodo-c. This option can be used to build a smaller library.
  • Major: Depend on kodo-core, kodo-rlnc, kodo-fulcrum and kodo-reed-solomon instead of kodo (kodo has been split to multiple repositories).
  • Major: Replaced kodo_has_set_trace_callback, kodo_has_set_trace_stdout and kodo_has_set_trace_off `` with ``kodo_has_trace_interface.
  • Major: Replaced kodo_has_set_systematic_off with kodo_has_systematic_interface.
  • Major: Renamed kodo_has_partial_decoding_tracker to kodo_has_partial_decoding_interface.
  • Minor: Added the Reed-Solomon codec (kodo_reed_solomon code type).
  • Major: Upgrade to kodo 34
  • Major: Renamed kodo_is_partial_complete to kodo_is_partially_complete.
  • Major: Renamed kodo_symbols_seen to kodo_symbols_partially_decoded.

7.0.1

  • Patch: Removed the post() call on the task generator of the shared library, which led to problems in dependent projects.

7.0.0

  • Minor: Completely rewrote the C bindings backend to use Kodo's new polymorphic API.
  • Minor: Added fulcrum stack.
  • Major: Renamed kodo_delete_encoder_factory and kodo_delete_decoder_factory to kodo_delete_factory.
  • Major: Renamed kodo_delete_encoder and kodo_delete_decoder to kodo_delete_coder.
  • Major: Upgrade to kodo 33
  • Major: Upgrade to waf-tools 3
  • Minor: Upgrade to gtest 3
  • Major: Removed support for deep storage (shallow storage is used for all codecs).
  • Major: The trace API is available in all codecs (option removed).
  • Major: Split kodo_set_symbol to const and mutable variants: kodo_set_const_symbol and kodo_set_mutable_symbol.
  • Major: Split kodo_set_symbols to const and mutable variants: kodo_set_const_symbols and kodo_set_mutable_symbols.
  • Major: Removed copy_from_symbol and copy_from_symbols since they are not used with shallow storage.

6.0.0

  • Major: Renamed files to follow the name of the class defined in the files.
  • Major: Upgrade to kodo 30.
  • Minor: Added perpetual stack.
  • Major: Renamed enum values kodo_full_rlnc, kodo_sparse_seed_rlnc, kodo_seed_rlnc to kodo_full_vector, kodo_sparse_seed, kodo_seed respectively, to better follow the Kodo API.
  • Major: Added context pointer to trace callback.

5.0.0

  • Major: Renamed copy_symbol and copy_symbols to copy_from_symbol and copy_from_symbols to their name in kodo 29.
  • Major: Upgrade to kodo 29
  • Major: Upgrade to fifi 20
  • Major: Renamed trace and trace_callback to the appropriate names from the new kodo version.
  • Major: Upgrade to kodo 27
  • Minor: Added buildbot.py for coverage reports.
  • Minor: Added kodo_has_write_payload to check if a coder provides the kodo_write_payload function.

4.0.0

  • Major: Upgrade to kodo 26
  • Major: Renamed kodo_symbol_pivot to kodo_is_symbol_pivot to match the function name in Kodo.

3.1.0

  • Minor: Added the kodo_sparse_seed_rlnc code type that implements a sparse seed-based RLNC codec. The code density should be set on the encoder side. The maximum size of the coding header is 9 bytes.
  • Minor: Moved the factory functions from kodoc.cpp to separate translation units in order to decrease the compilation time. The optimizer might use gigabytes of RAM when instantiating a lot of coder stack variants in a single cpp file. This problem is mitigated with this separation.
  • Minor: Added a seed-based RLNC codec (kodo_seed_rlnc).

3.0.0

  • Minor: Added sparse RLNC encoder.
  • Major: Upgrade to kodo 25
  • Major: Upgrade to fifi 19
  • Minor: Added simple throughput benchmark in benchmark/kodoc_throughput
  • Minor: Extended the C API with functions for reading and writing symbols directly on the decoder and encoder.
  • Minor: Added a shallow full RLNC codec.
  • Major: Upgrade to sak 14
  • Minor: Re-enabled the build task for the kodo-c static library.

2.0.0

  • Major: Restructured the API according to the Hourglass pattern that was presented at CppCon 2014: https://www.youtube.com/watch?v=PVYdHDm0q6Y This pattern encapsulates the complexity of the underlying C++ libraries by hiding all implementation details behind a simple C89 API. It makes providing bindings from other languages easier, facilitates integration with other C++ projects and build systems, and insulates from ABI issues.
  • Minor: Update to waf 1.8.0-pre1
  • Minor: Made python files comply with pep8
  • Major: Upgrade to kodo 21
  • Major: Upgrade to fifi 15
  • Major: Upgrade to sak 13
  • Major: Added recycle dependency
  • Patch: The kodo_is_symbol_decoded() function call was forwarded to the wrong kodo function.
  • Major: Removed debug functions (Replaced by trace layers)
  • Minor: Add trace layer functions
  • Minor: Added the sliding window algorithm
  • Minor: Added new examples:
    sliding_window, switch_systematic_on_off use_trace_layers
  • Minor: Updated examples:
    encode_decode_simple encode_decode_on_the_fly udp_sender_receiver
  • Minor: Implemented method kodo_read_feedback
  • Minor: Implemented method kodo_write_feedback

1.7.0

  • Minor: Bump dependency to Kodo version 14.x.y

1.6.0

  • Minor: Bump dependency to Kodo version 13.x.y

1.5.0

  • Minor: Added API for creating debug stacks and printing debug information.

1.4.0

  • Minor: Added API to control systematic encoding. Systematic encoding means that all source symbols will be sent once un-coded before coding begins.

1.3.0

  • Minor: Bump dependency to Kodo version 12.x.y
  • Minor: Improve on-the-fly encoding / decoding support

1.2.1

  • Patch: Allow compilation without using a makespec

1.2.0

  • Minor: Added support for on-the-fly encoding and a corresponding example.
  • Patch: Setting c++11 compiler flag to -std=c++0x in the makefile/Makefile

1.1.0

  • Minor: Added the standalone archiver Waf tool. The tool makes it possible to create self contained archives of the Kodo C bindings i.e. it contains all needed dependencies.

1.0.0

  • Major: Initial version of the Kodo C bindings based on Kodo version 11.x.y.
