Latest

  • tbd

12.0.0

  • Major: Upgrade to boost 4
  • Major: Upgrade to tables 8
  • Minor: Added a test for specifying options using BENCHMARK_OPTION.
  • Major: Replaced boost::chrono references with std::chrono.

11.2.0

  • Minor: Add the prepare_table(...) function to allow benchmarks to create their needed result columns in advance. The allocation of new columns during the benchmark can disrupt the performance measurements.

11.1.2

  • Patch: Reserve runs in result table.

11.1.1

  • Patch: Added virtual constructor to printer.

11.1.0

  • Minor: Added a CPU warm-up time before starting first benchmark to avoid unfavorable results for the first few benchmarks. The time interval can be controlled by the --warmup_time option.

11.0.0

  • Major: Upgrade to waf-tools 4
  • Major: Upgrade to boost 3
  • Major: Upgrade to tables 7
  • Minor: Upgrade to gtest 4

10.0.0

  • Major: Upgrade to waf-tools 3
  • Major: Upgrade to boost 2
  • Major: Upgrade to tables 6
  • Minor: Upgrade to gtest 3
  • Minor: Added buildbot.py for coverage reports.

9.1.0

  • Minor: Adding a way to skip a benchmark at run-time. An example use-case for this is benchmarking run-time dispatched CPU specific instructions e.g. SSE, AVX etc.

9.0.1

  • Patch: Fixed warnings in using_options.cpp.
  • Patch: Added the proper use flags for all targets

9.0.0

  • Major: Updated the benchmark macros. There are now three variants to choose from when declaring a benchmark. This introduced one breaking change: The BENCHMARK_F macro has been renamed to BENCHMARK_F_INLINE. You should now use BENCHMARK_F if your fixture has a test_body() function that you want to run automatically. See gauge.hpp for a description of the different macros.
  • Patch: Fix version define.

8.0.0

  • Major: Upgrade to tables 5.x.y
  • Major: Made single argument constructors explicit
  • Minor: Fixed style issues
  • Minor: Update to waf 1.8.0-pre1
  • Minor: Made python files comply with pep8
  • Minor: Added command line options to print testcases and benchmarks.
  • Minor: Added version.

7.1.0

  • Minor: Added newlines to the stdout_printer's output.

7.0.0

  • Major: Removed unused commandline_arguments class.
  • Major: Removed vector separator options form csv_printer as it was unused.
  • Minor: Added dry_run option to execute the benchmark initialization code without running the actual benchmark.
  • Minor: Added use_[printer_name] option to enable or disable certain printers.
  • Minor: Added stdout_printer which is a printer that can print results in a specified format to standard output.
  • Bug: If an exception occurred, gauge now returns an appropriate error code.

6.3.0

  • Minor: Added a convenience function add_default_printers() to the gauge runner. This enables most common printers in a project.

6.2.0

  • Minor: runner::run now catches all exceptions. The API has been extended with runner::run_unsafe which doesn't catch exceptions.

6.1.0

  • Bug: Removed configuration information from the result table.
  • Minor: Improved filter options for benchmark testing purposes.

6.0.0

  • Major: Started using tables version 4.
  • Major: Extracted tables and related logic to its own repository.

5.5.0

  • Minor: The python- and CSV-printers can now take the default output filename as a parameter.

5.4.0

  • Minor: Eased use of python output file.

5.3.0

  • Minor: Improved filtering options for filtering benchmarks and results.

5.2.1

  • Bug: Fix file printers so that they correctly detect the end of all benchmarks.

5.2.0

  • Minor: Adding time-stamping to the console printer to give an overview of the time spent in every step.
  • Minor: Added the option to control the CSV printer's value separator, the default is comma however this can now be changed command-line.

5.1.0

  • Minor: Cleanup

5.0.0

  • Minor: Update waf to version 1.7.10 and use the wurf_install_path tool.
  • Minor: Updated to waf-tools version 2.x.y
  • Minor: Added CSV (comma separated values) printer.
  • Major: Changed the benchmark interface. Implementers of new benchmarks may now register several measurement results in a single run. The new benchmark also supports specifying custom benchmark options (available on the command-line).
  • Minor: The benchmark fixtures are now only allocated when needed and destroyed after completing a benchmark. This releases resources allocated by previous benchmarks.
  • Minor: Added a number of unit-test for testing gauge itself.

4.0.0

  • Updated waf to use new external waf tools repository

3.0.0

  • Switched to mkspec enabled builds

2.0.0

  • Using .hpp extension instead of .h

1.0.0
