Changelog of @hackage/criterion 1.2.1.0

1.2.1.0

  • Add GCStatistics, getGCStatistics, and applyGCStatistics to Criterion.Measurement. These are inteded to replace GCStats (which has been deprecated in base and will be removed in GHC 8.4), as well as getGCStats and applyGCStats, which have also been deprecated and will be removed in the next major criterion release.

  • Add new matchers for the --match flag:

    • --match pattern, which matches by searching for a given substring in benchmark paths.
    • --match ipattern, which is like --match pattern but case-insensitive.

  • Export Criterion.Main.Options.config.

  • Export Criterion.toBenchmarkable, which behaves like the Benchmarkable constructor did prior to criterion-1.2.0.0.

1.2.0.0

  • Use statistics-0.14.

  • Replace the hastache dependency with microstache.

  • Add support for per-run allocation/cleanup of the environment with perRunEnv and perRunEnvWithCleanup,

  • Add support for per-batch allocation/cleanup with perBatchEnv and perBatchEnvWithCleanup.

  • Add envWithCleanup, a variant of env with cleanup support.

  • Add the criterion-report executable, which creates reports from previously created JSON files.

1.1.4.0

  • Unicode output is now correctly printed on Windows.

1.1.4.0

  • Add Safe Haskell annotations.

  • Add --json option for writing reports in JSON rather than binary format. Also: various bugfixes related to this.

  • Use the js-jquery and js-flot libraries to substitute in JavaScript code into the default HTML report template.

  • Use the code-page library to ensure that criterion prints out Unicode characters (like ², which criterion uses in reports) in a UTF-8-compatible code page on Windows.

  • Give an explicit implementation for get in the Binary Regression instance. This should fix sporadic criterion failures with older versions of binary.

  • Use tasty instead of test-framework in the test suites.

  • Restore support for 32-bit Intel CPUs.

  • Restore build compatibilty with GHC 7.4.

1.1.1.0

  • If a benchmark uses Criterion.env in a non-lazy way, and you try to use --list to list benchmark names, you'll now get an understandable error message instead of something cryptic.

  • We now flush stdout and stderr after printing messages, so that output is printed promptly even when piped (e.g. into a pager).

  • A new function runMode allows custom benchmarking applications to run benchmarks with control over the Mode used.

  • Added support for Linux on non-Intel CPUs.

  • This version supports GHC 8.

  • The --only-run option for benchmarks is renamed to --iters.

1.1.0.0

  • The dependency on the either package has been dropped in favour of a dependency on transformers-compat. This greatly reduces the number of packages criterion depends on. This shouldn't affect the user-visible API.

  • The documentation claimed that environments were created only when needed, but this wasn't implemented. (gh-76)

  • The package now compiles with GHC 7.10.

  • On Windows with a non-Unicode code page, printing results used to cause a crash. (gh-55)

1.0.2.0

  • Bump lower bound on optparse-applicative to 0.11 to handle yet more annoying API churn.

1.0.1.0

  • Added a lower bound of 0.10 on the optparse-applicative dependency, as there were major API changes between 0.9 and 0.10.
