ruby.git/test/benchmark, branch ruby_2_2

Ruby can delay arbitrarily because Ruby is not a realtime system,

test_benchmark.rb: use assert_in_epsilon

2014-08-31T02:49:50+00:00

* test/benchmark/test_benchmark.rb (test_realtime_output): use
  assert_in_epsilon which compares in relative range, instead of
  assert_in_delta which compares in absolute range.

test_benchmark.rb: extend sleep time

2014-08-30T06:18:57+00:00

* test/benchmark/test_benchmark.rb: extend sleep time, as 1ms is
  too short on some environments.

lib/benchmark.rb: speedup by reducing allocations

2014-08-24T02:03:06+00:00

* lib/benchmark.rb (module Benchmark): define BENCHMARK_CLOCK
  (realtime): use Process.clock_gettime(BENCHMARK_CLOCK)
  [Feature #10165]

* test/benchmark/test_benchmark.rb (test_realtime_output): new test

  patched by Benoit Daloze. [ruby-core:37593] [Bug #4940]

* lib/benchmark (Benchmark#bmbm): bmbm should be consistent with bm
  for the return value.

* test/benchmark: remove preemptive test instead of skipping
  I removed the preemptive test I wrote for Feature #4197.
  I'll add it back when the implementation will be able to satisfy it.

* lib/benchmark (Benchmark#bmbm): remove useless explicit call,
  #format is an alias of #to_s test/benchmark: add a test for
  format of long time.

* lib/benchmark: fix label width: always add 1 to ensure there is a
  space delimiter even with times over 100s
  When I asked for Feature #4197, I wanted to make delimiting spaces
  consistent for #bm and #bmbm.
  But with times over 100s, the output contains no space between the
  label and the first time (user).
  Now both ensure there is always a space, even if that means 3 spaces
  with times under 10s (because it is formatted as %10.6f)

* test/benchmark: let labels be a constant
  lib/benchmark (Benchmark#realtime): avoid creating an unused Proc
  lib/benchmark (Benchmark#benchmark): use ensure clause to restore
  STDOUT.sync, as in #bmbm

  replace '-' as space. On NetBSD, subtract between two Process.times
  after and before the short process may return negative value like:
  t0=Process.times; yield; t1=Process.times; p t1.utime-t0.utime

* test/benchmark/test_benchmark.rb (#capture_bench_output):

2011-02-01T04:33:00+00:00

	  Added explict sleep. Windows have imprecise time support.
	  Thus Tms.new.Add!{} may be or may be not equal 0. The
	  test failure started since r30747.
