Changelog History

  • v0.2.5 Changes

    September 08, 2019
    • โž• Add GHCJS support (statistical analysis is not supported)
    • ๐Ÿ›  Fix issue with perRunEnv
    • โฌ‡๏ธ Drop support for GHC 7.8
  • v0.2.4 Changes

    October 20, 2018
    • Enhancement: Add nfAppIO and whnfAppIO functions, which take a function and its argument separately like nf/whnf, but whose function returns IO like nfIO/whnfIO. This is useful for benchmarking functions in which the bulk of the work is not bound by IO, but by pure computations that might otherwise be optimized away if the argument is known statically.

    • Bug Fix: Pass -m exact option to the child processes used to run benchmarks in an isolated manner. This avoids running a wrong benchmark due to the default prefix match.

  • v0.2.3 Changes

    July 07, 2018
    • โž• Add a new benchmark matching option "-m exact" to match the benchmark name exactly.
  • v0.2.2 Changes

    June 25, 2018
    • Write data to CSV file in quick mode too.
    • ๐Ÿ›  Fix the CSV file header to match with the data rows for the --csvraw case.
    • ๐Ÿ›  Fix issue with GC metrics in 32 bits that would silently wrap and failure in optional machinery.
    • โœ… Simplify dependencies in tests using foudation checks.
  • v0.2.1 Changes

    January 17, 2018
    • Inline math-functions & mwc-random:
      • Remove most functions, instances and types, that are unnecessary for gauge
      • Remove unsafe seeding with partial seed (unused in gauge anyway)
      • Remove vector-th-unbox dependency (transitively template-haskell, pretty, ghc-boot-th)
      • Remove time dependency
    • Re-add Gauge.Benchmark to Gauge.Main to keep the transition between criterion and gauge easy
    • ๐Ÿ›  Fix cycles reporting on linux, osx and windows
    • โž• Add some extra callstack for reporting on partial function
    • ๐Ÿ›  Fix compilation with Semigroup => Monoid (compilation on 8.4). still unsupported
    • โž• Add some color on terminal output
  • v0.2.0 Changes

    January 05, 2018
    • ๐Ÿ“š Usability: Simplify and organize the documentation and user APIs.
    • Functionality:
      • Add measurement and reporting of more performance counters on Unices (collected via getrusage) for example page faults, user time, system time and rss are now available in verbose mode.
      • Re-enable CSV analysis with the same output format as criterion (--csv)
      • Add CSV measurement dumping with --csvraw
    • ๐Ÿ‘ Control: Provide better control over measurement process with --min-samples, --min-duration and --include-first-iter flags.
    • Speed: Add --quick flag that provides results much faster (10x) without using statistical analysis.
    • Reliability:
      • Fix a bug in GC stats collection and reporting with GHC 8.2 that caused incorrect reporting of some GC stats.
      • Fix a bug in statistical regression that caused incorrect reporting of mean and other stats.
      • Improve reliability by isolating benchmarks from one another using the --measure-with flag. The results of one benchmark are no longer affected by other benchmarks because each benchmark runs in a separate process.
      • Introduce an optional value type Optional with an efficient runtime representation to replace the ad-hoc fromXXX functions and the untyped approach.
    • Modularity:
      • Introduce --measure-only flag that allows just measurement and no analysis or reporting.
      • Provide modular build, measurement code is cleanly separated from statistical analysis code. As a result a leaner version can now be built without analysis code (controlled by the analysis build flag).
      • Clean, refactor & rewrite source code
    • โœ‚ Remove code-page dependency
  • v0.1.3 Changes

    October 30, 2017

  • v0.1.0 Changes
