0.4.1

  • Force GC before collecting RTSStats, otherwise measurements are inaccurate.
  • Restore locale encoding after defaultMain.

0.4

  • Switch nf, nfIO and nfAppIO to evaluate outputs to a normal form with rnf instead of force. It means that parts of the output, which have already been forced, can be garbage collected early, without waiting for the entire output to be allocated at the same time. This decreases benchmarking overhead in many scenarios and brings the behaviour in line with criterion. See #39 for discussion.
  • Drop support of tasty < 1.4.
  • Make IO benchmarks immune to -fspec-constr-count limit.
  • Decomission debug build flag.
  • Decomission warning when --timeout is absent.
  • Add instance {Eq,Ord,Num,Fractional} {RelStDev,FailIfSlower,FailIfFaster}.
  • Add instance {Eq,Ord} {CsvPath,SvgPath,BaselinePath}.

0.3.5

  • Support tasty-1.5.
  • Report benchmarking progress.

0.3.4

  • Force single-threaded execution in defaultMain.
  • Expose measureCpuTimeAndStDev helper to analyse benchmarks manually.

0.3.3

  • Drop support of tasty < 1.2.3.
  • Make benchmarks immune to -fspec-constr-count limit.

0.3.2

  • Add locateBenchmark and mapLeafBenchmarks.
  • Support measuring of wall-clock time.
  • Make messages for baseline comparison less ambiguous.
  • Graceful degradation on non-Unicode terminals.

0.3.1

  • Add bcompareWithin for portable performance tests.
  • Add tasty and debug build flags.

0.3

  • Report mean time with 3 significant digits.
  • Report peak memory usage, when run with +RTS -T.
  • Run benchmarks only once, if RelStDev is infinite.
  • Make Benchmarkable constructor public.
  • Expose measureCpuTime helper to run benchmarks manually.
  • Expose CsvPath, BaselinePath, SvgPath.

0.2.5

  • Fix comparison against baseline.

0.2.4

  • Add a simplistic SVG reporter.
  • Add bcompare to compare between benchmarks.
  • Throw a warning, if benchmarks take too long.

0.2.3

  • Prohibit duplicated benchmark names in CSV reports.

0.2.2

  • Remove NFData constraint from whnfIO.

0.2.1

  • Fix integer overflow in stdev computations.

0.2

  • Add env and envWithCleanup.
  • Run console and CSV reporters in parallel.
  • Extend console reporter and export it as consoleBenchReporter.
  • Add comparison against baseline and relevant options.
  • Export RelStDev option.
  • Export benchIngredients.

0.1

  • Initial release.
