[DRE-maint] Bug#795677: ruby-hitimes: Non-determinstic FTBFS due to unreliable timing benchmarks in tests

[Chris Lamb]

Source: ruby-hitimes
Version: 1.2.1-2
Severity: serious
Justification: fails to build from source

Dear Maintainer,

ruby-hitimes non-deterministically fails to build from source due to
unreliable
timing benchmarks in tests:

  [..]
  
    7) Hitimes::TimedValueMetric can measure a block of code from an
    instance
       Failure/Error: t.duration.should be_within(0.004).of(0.15)
         expected 0.156623768 to be within 0.004 of 0.15
       # ./spec/timed_value_metric_spec.rb:125:in `block (2 levels) in
       <top (required)>'
  
  Deprecation Warnings:
  
  Requiring `rspec/autorun` when running RSpec via the `rspec` command
  is deprecated. Called from
  /tmp/buildd/ruby-hitimes-1.2.1/spec/spec_helper.rb:7:in `<top
  (required)>'.
  
  Using `should` from rspec-expectations' old `:should` syntax without
  explicitly enabling the syntax is deprecated. Use the new `:expect`
  syntax or explicitly enable `:should` with `config.expect_with(:rspec)
  { |c| c.syntax = :should }` instead. Called from
  /tmp/buildd/ruby-hitimes-1.2.1/spec/hitimes_spec.rb:8:in `block (2
  levels) in <top (required)>'.
  
  
  If you need more of the backtrace for any of these deprecations to
  identify where to make the necessary changes, you can configure
  `config.raise_errors_for_deprecations!`, and it will turn the
  deprecation warnings into errors, giving you the full backtrace.
  
  2 deprecation warnings total
