Subject: [PATCH 017/258] Beef up tests for when rspec-expectations is not
 available.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Specifically, in #1826, we changed the conditional for
whether or not to assign a generated description from
RSpec::Matchers for examples with no doc string. Before
#1826, the conditional was:

  assign_generated_description if RSpec.configuration.expecting_with_rspec?

In #1826 it changed to:

  assign_generated_description if defined?(::RSpec::Matchers)

We didn’t update the spec meant for that case to match, but it continued
to pass (as a false positive) due to rspec/rspec-mocks#874. @samphippen’s
fix in rspec/rspec-mocks#884 surfaced the issue (as the spec now failed)
so I decided to improve the tests.

- The spec now simulates the `RSpec::Matchers` constant being undefined
  to simulate the correct condition. We also have to prevent it from
  being autoloaded.
- The cukes for minitest/test-unit did not sufficiently cover this case,
  because the aforementioned autoload would autoload RSpec::Matchers,
  so we have to simulate rspec-expectations being completely uninstalled.
  Then the cukes properly fail if we break the `if defined?(::RSpec::Matchers)`
  conditional.

+      #   * Some external libraries issue warnings, which we can't do anything about.
+      #     Since we are trying to prevent _any_ warnings from loading RSpec, it's
+      #     easiest to avoid loading those libraries entirely.
+      #   * Some external libraries load many stdlibs. Here we allow a known set of
+      #     directly loaded stdlibs, and we're not directly concerned with transitive
+      #     dependencies.
+      #   * We're really only concerned with these issues w.r.t. rspec-mocks and
+      #     rspec-expectations from within their spec suites. Here we care only about
+      #     rspec-core, so avoiding loading them helps keep the spec suites independent.
+      #   * These are some of the slowest specs we have, and cutting out the loading
+      #     of external libraries cuts down on how long these specs take.
+      #
+      # To facilitate the avoidance of loading certain libraries, we have a bunch

+      #   * erb -- loaded by `ConfigurationOptions` so `.rspec` can use ERB. Loads other stdlibs (strscan, cgi/util).

Subject: [PATCH 036/258] Remove duplicate spec.

This exact spec is duplicated on line 775.
I suspect this was written for the old `--line-number` CLI flag
and got updated to the `file_path:line_num` form when
we dropped support for `--line-number`, creating the duplication.

It’s important that you see the expectation fail
(it’s how you “test the test”, so to speak, and
you can confirm it gives you a good failure message),
so let’s not skip that step.

+## A Word on Scope
+
+RSpec has two scopes:
+
+* **Example Group**: Example groups are defined by a `describe` or
+  `context` block, which is eagerly evaluated when the spec file is
+  loaded. The block is evaluated in the context of a subclass of
+  `RSpec::Core::ExampleGroup`, or a subclass of the parent example group
+  when you're nesting them.
+* **Example**: Examples, and any other blocks with per-example semantics
+  (such as a `before(:example)` hook), are evaluated in the context of
+  an _instance_ of the example group class to which the example belongs.
+  Examples are _not_ executed when the spec file is loaded; instead,
+  RSpec waits to run any examples until all spec files have been loaded,
+  at which point it can apply filtering, randomization, etc.
+
+To make this more concrete, consider this code snippet:
+
+``` ruby
+RSpec.describe "Using an array as a stack" do
+  def build_stack
+    []
+  end
+
+  before(:example) do
+    @stack = build_stack
+  end
+
+  it 'is initially empty' do
+    expect(@stack).to be_empty
+  end
+
+  context "after an item has been pushed" do
+    def build_stack
+      super.push :item
+    end
+
+    it 'allows the pushed item to be popped' do
+      expect(@stack.pop).to eq(:item)
+    end
+  end
+end
+```
+
+Under the covers, this is (roughly) equivalent to:
+
+``` ruby
+class UsingAnArrayAsAStack < RSpec::Core::ExampleGroup
+  def build_stack
+    []
+  end
+
+  def before_example
+    @stack = build_stack
+  end
+
+  def it_is_initially_empty
+    expect(@stack).to be_empty
+  end
+
+  class AfterAnItemHasBeenPushed < self
+    def build_stack
+      super.push :item
+    end
+
+    def it_allows_the_pushed_item_to_be_popped
+      expect(@stack.pop).to eq(:item)
+    end
+  end
+end

+Feature: Only Failures
+
+  The `--only-failures` option filters what examples are run so that only those that failed the last time they ran are executed. To use this option, you first have to configure `config.example_status_persistence_file_path`, which RSpec will use to store the status of each example the last time it ran.
+
+  There's also a `--next-failure` option, which is shorthand for `--only-failures --fail-fast --order defined`. It allows you to repeatedly focus on just one of the currently failing examples, then move on to the next failure, etc.
+
+  Either of these options can be combined with another a directory or file name; RSpec will run just the failures from the set of loaded examples.
+
+  Background:
+    Given a file named "spec/spec_helper.rb" with:
+      """ruby
+      RSpec.configure do |c|
+        c.example_status_persistence_file_path = "examples.txt"
+      end
+      """
+    And a file named ".rspec" with:
+      """
+      --require spec_helper
+      --order random
+      --format documentation

+    And a file named "spec/array_spec.rb" with:
+      """ruby

+
+        it "checks for inclusion of 2" do
+          expect([1, 2]).to include(2)
+        end
+
+        it "checks for inclusion of 3" do
+          expect([1, 2]).to include(3) # failure

Subject: [PATCH 080/258] Load only files with failures when using `rspec
 --only-failures`.

Loading ALL spec files when only a handful have failures is inefficient
and could make the run take significantly longer. Note that we only do
this if no file or directory arg is passed to `rspec`. If the user
passes anything, we load what they tell us to load.

Subject: [PATCH 081/258] Move `only_failures` config specs into their own
 file.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

`configuration_spec.rb` is too huge. The API needs to
remain large to support the configurability of RSpec,
but we don’t need to keep all the specs in one file.
I want to start breaking off different chunks into their
own files. This is a first step towards that.

Subject: [PATCH 082/258] Ensure derived values are updated when the config
 setting updates.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

It’s easier to make this work by moving the
`spec_files_with_failures` and the
`last_run_statuses` methods off of `world`
and over to `configuration.

as they were before but now they are on config so we
want to avoid that.

Before, we only did so when no file or directory arg was passed
to `rspec`, but it's better to take the intersection of files
matching the provided args and files with failures.

Subject: [PATCH 086/258] Use "unknown" for :last_run_status when we don't have
 a value.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This ensures that the value is consistent — before for an unknown
case it could either be `nil` or `"unknown"`.

We've also moved the constant into configuration, so that we can
avoid the cost of loading `example_status_persister` (via constant
access since it is setup to be autoloaded) if the user hasn't
configured the feature.

+  end
+
+  RSpec.describe SomeClass do
+    include_example "some example", "parameter1"
+    include_example "some example", "parameter2"
+  end
+  ```
+
+  You're actually doing this (notice that first example will fail):
+
+  ```ruby
+  RSpec.describe SomeClass do
+    \# Reordered code for better understanding of what is happening
+    let(:something) { "parameter1" }
+    let(:something) { "parameter2" }
+
+    it "uses the given parameter" do
+      \# This example will fail because last let "wins"
+      expect(something).to eq("parameter1")
+    end
+
+    it "uses the given parameter" do
+      expect(something).to eq("parameter2")
+    end
+  end
+  ```
+
+  To prevent this kind of subtle error a warning is emitted if you declare multiple
+  methods with the same name in the same context. Should you get this warning
+  the simplest solution is to replace `include_example` with `it_behaves_like`, in this
+  way method overriding is avoided because of the nested context created by `it_behaves_like`

Subject: [PATCH 095/258] Fix `RSpec::Core::RakeTask#failure_message`.

`system` returns a boolean value to indicate success/failure,
but the use of `failure_message` was in a `rescue` block that
never got executed.  It appears this has been broken since
ea70e4edbbc52846dcd63308ee349166bbcef29c. Before that commit,
we used `Rake::FileUtilsExt#ruby`, which does indicate failure
by raising an error (and thus the `rescue` was correct). In
ea70e4edbbc52846dcd63308ee349166bbcef29c, we switched to using
`system` and the rescue was left in place but never got hit
anymore.

The lack of test coverage here is why we never noticed, so I
addressed that as well.

Subject: [PATCH 101/258] =?UTF-8?q?Make=20`=E2=80=94order=20random`=20more?=
 =?UTF-8?q?=20deterministic.?=
MIME-Version: 1.0

When you’re troubleshooting an order dependent
failure, you want to get the repro case down to
a minimal run that loads and runs as few specs
as possible. With the old random ordering implementation,
that was hard to achieve because while rerunning with
a given seed produced the same order when the exact
same set of examples were loaded, the ordering would
be completely different when a subset was loaded.

By ordering by `hash(seed + example_id)` it ensures
that the ordering of any two examples should stay
consistently regardless of how many other examples are
loaded.

Jenkins or MD5 is significantly slower than `shuffle`,
but I think the tradeoff is worth it here. This isn’t
a hot spot.

Subject: [PATCH 111/258] Revert "Warn users when overriding methods (via let,
 def or define_method) in the same example group."

This reverts the lib and spec pieces of e072e5358b85a971010bc1a22d04eeca646321c8.

The warning is overzealous. After upgrading a project to RSpec HEAD, I
got spammed with tons of warnings of situations that weren't actually
problematic.  For example, it's common to define a `let` in a shared
context that provides a default value, and than to purposefully override
that in a host group where the shared context is included. We should'nt
warn in such a situation, but this did warn.

See #1903 for the original code this reverts.

Subject: [PATCH 112/258] Don't purge example groups when a `--fail-fast`
 failure is hit.

Doing so prevents us from persisting updates to example statuses,
interfering with `--next-failure` from working properly.

The purging was introduced in 6946d2d but has actually done nothing
since fde59555903644ba13df27519f494b4f874d60e8, when the runner switched
from doing `@world.example_groups.map { |g| g.run }` to
`order(@world.example_groups).map { |g| g.run }`. With the ordering
applied, purging the example group no longer had the intended "abort
the loop early" effect, since we were now mapping over a derived ordered
array. The purging isn't really needed anyway; each example group aborts
early if `wants_to_quit` is set, so we still don't run any more examples
or groups.

It might be nice to bring back the "abort the loop early" effect but
I can't think of an elegant way to do it and it doesn't seem worth
the complexity at this point.

Fixes #1914.

Subject: [PATCH 115/258] Make memoized helpers threadsafe

See https://github.com/rspec/rspec-core/pull/1858 for discussion.

The unsquashed version can be seen at
https://github.com/JoshCheek/rspec-core/tree/threadsafe-let-block-unsquashed
in case the intermediate state and thoughts have value.

Motivation
----------

When working in a truly threaded environment (e.g. Rbx and JRuby),
you can write a test like the one below, which should pass.
But, it will fail sometimes, because two threads request the uninitialized counter
concurrently. The first one to receive the value will then be
incrementing a counter, that is later overwritten when the second
thread's let block returns.

You can verify this by running the code sample below in Rubinius.
After some number of attempts, the value will be less than 10k.
If you then make the `let` block a `let!` block, it will memoize
before the threads are created, and the values will be correct again.
While this is a reasonable solution, it is incredibly confusing
when it arises (I spent a lot of hours trying to find the bug in my code),
and requires that the user understand it's something they need to
be aware of and guard against.

```ruby
class Counter
  def initialize
    @mutex = Mutex.new
    @count = 0
  end

  attr_reader :count

  def increment
    @mutex.synchronize { @count += 1 }
  end
end

RSpec.describe Counter do
  let(:counter) { Counter.new }

  it 'increments the count in a threadsafe manner' do
    threads = 10.times.map do
      Thread.new { 1000.times { counter.increment } }
    end
    threads.each &:join
    expect(counter.count).to eq 10_000
  end
end
```

Relevant Changes
----------------

* Adds `--[no]-threadsafe` command-line option
* `RSpec::Core::Configuration#threadsafe{?,=}`
  (notation there is from bash expansion)
  setting, defaults to `true`
* Mamoized is a threadsafe object instead of a hash,
  so rename `RSpec::Core::MemoizedHelpers::ContextHookMemoizedHash`
  to        `RSpec::Core::MemoizedHelpers::ContextHookMemoized`

  Create an object because only #fetch was being called on the hash,
  and to make that threadsafe required adding a new method.
  At that point, there is no value in having it subclass Hash,
  having to support an entire API that nothing else uses.
  So just make it an object which wraps a hash and presents a memoized
  getter/setter. Also named the method in such a way as to make it
  very clear that it's not a hash, so a dev won't mistakenly think
  they are working with one when they aren't.
* Adds private class `RSpec::Core::ReentrantMutex`,
  which is basically just `Monitor` from the stdlib.
* `RSpec::Core::ExampleGroup#initialize` now calls super so that
  `RSpec::Core::MemoizedHelpers` can initialize the memoized helper
  when the example is instantiated, rather than when it is accessed,
  as this is not threadsafe.

Context and daydreams
---------------------

* PR can be seen unsquashed at:
  https://github.com/JoshCheek/rspec-core/tree/threadsafe-let-block-unsquashed
  This is my first "real" squash, and it wasn't super smooth. I think I
  got it right, in the end, but if you're looking at it going "wtf?", and
  want some more context into the squash itself, I documented it at:
  https://gist.github.com/JoshCheek/017c399641a44286428b
  Also, while I'm pretty sold against anything that changes history,
  there's probably a way to do this that's better than what I did,
  so if you read that and have insights, shoot em my wya, I'd love to get better!
* This does not add any stedlib dependencies as they affect the test
  environment of all users.
* The threads need to be reentrant, which will allow a let block in a thread to
  access its parent let block. This can be achieved with Monitor from
  the stdlib. However, to avoid the dependency, the code was copied from
  https://github.com/ruby/ruby/blob/eb7ddaa3a47bf48045d26c72eb0f263a53524ebc/lib/monitor.rb#L9
  and pasted/edited into `lib/rspec/core/reentrant_mutex.rb`
  This way the user's test environment is preserved, but we still get
  reentrant mutexes.
* Reentrant mutexes are built on top of normal mutexes. These are in
  core now, but for 1.8.7, were defined in the stdlib's thread.rb
  So, similarly, copy that code into `RSpec::Core::ReentrantMutex::MUTEX`
  (capitalization due to Rubocop rules),
  with a note stating that it should be deleted once 1.8 support is dropped.
  If there is a Mutex available already, though, as on 1.9.x+, it will use that.
* Adds a development dependency on a gem, thread_order, which I extracted out of this work.
  Its purpose was to ease the difficulty and opacity of specifying what should
  happen and when, with regards to getting the threads into situations to illustrate
  expected behaviour. It similarly works on 1.8.7 - 2.2, and on JRuby and Rbx,
  without dependencies on the stdlib.
* Add benchmark for threadsafe let block, here is a summary:

  ```
  MRI 2.2

  1 call to let -- each sets the value
    non-threadsafe (original):   830988.5 i/s
    non-threadsafe (config)  :   665661.9 i/s - 1.25x slower
    threadsafe               :   323574.9 i/s - 2.57x slower
  10 calls to let -- 9 will find memoized value
    non-threadsafe (original):   346302.0 i/s
    non-threadsafe (config)  :   309970.2 i/s - 1.12x slower
    threadsafe               :   208946.3 i/s - 1.66x slower
  1 call to let which invokes super
    non-threadsafe (original):   591906.3 i/s
    non-threadsafe (config)  :   511295.0 i/s - 1.16x slower
    threadsafe               :   246079.6 i/s - 2.41x slower
  10 calls to let which invokes super
    non-threadsafe (original):   297422.6 i/s
    non-threadsafe (config)  :   264045.8 i/s - 1.13x slower
    threadsafe               :   170853.1 i/s - 1.74x slower
  ```

  The threasafe let is 1.5 to 2.5 times slower than the original hash
  implementation. The hash alternative is 1.1 to 1.25 times slower.
  If this matters for you, you can configure which one you want to use.

  Either way, you can call the method defined by a let block hundreds of
  thousands of times a second.

Subject: [PATCH 116/258] Tweak a few things about the threadsafe let solution
 from #1858.

1). Remove `--threadsafe` CLI option.

In general, we don't expose every config option via the CLI.
We want to make it easy for users to run `rspec --help` and
find the options that they are commonly going to want to customize
for a particular CLI run. I don't think `--threadsafe` is one of
those -- it's more something that'll be turned off globally for the
project or not touched at all, and as such, it adds noise to
the `--help` output to include it.

2). Extract Mutex class into its own file.

- Remove need for use of `MUTEX` over `Mutex`.
- No reason to force Ruby to parse the code
  for 1.8.7 Mutex implementation on other Rubies.

3). Remove threadsafe scenario.

A note about threadsafey is sufficient for the docs. Having
a full threadsafety example spec in the scenario is more
detail than users are likely to want to read.

Subject: [PATCH 117/258] Remove unnecessary `uniq!` call.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

No code is faster than no code.

It appears that the `uniq!` comes from micronaut:

https://github.com/rspec/rspec-core/commit/afca72820329d5f84aa60fcecb7bf188d8394919#diff-117c39fd53498f0c3f5a53efb3c24f05R52

However, it’s clear that it’s not actually needed. It didn’t do
anything for 2 years due to being a `uniq` (not `uniq!`)
call with an ignored return value, beginning in this commit:

https://github.com/rspec/rspec-core/commit/ad9281626a8e8bafe3c97d5e97a18fa9f981d74e#diff-3831ad1cf9ec21d559640a066a9d3bc8R40

…until this one, 2 years later:

67923ba940f0360740292710e798836c1c353d20

I don’t think there’s any way for there to be any duplicates to begin with, so it’s safe to remove.

`filter_manager.prune` avoids mutating the input array,
like a good citizen, so there’s no need to dup it.

Subject: [PATCH 129/258] Make option parsing simpler and more consistent.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Do not mutate the provided args.
- Include `:files_or_directories_to_run` in the
  returned options hash. After all, it’s part of
  the parsed options.

This will help support the new `--bisect` option
by making it easy for us to split CLI args into options
(which get re-used throughout the bisect process) and
files_or_directories_to_run (which get replaced during
bisect).

+Feature: Bisect
+
+  RSpec's `--order random` and `--seed` options help surface flickering examples that only fail when one or more other examples are executed first. It can be very difficult to isolate the exact combination of examples that triggers the failure. The `--bisect` flag helps solve that problem.
+
+  Pass the `--bisect` option (in addition to `--seed` any other options) and RSpec will repeatedly run subsets of your suite in order to isolate the minimal set of examples that reproduce the failure.
+
+  Scenario: Use `--bisect` flag to create a minimal repro case for the ordering dependency
+    Given a file named "lib/calculator.rb" with:
+      """ruby
+      class Calculator
+        def self.add(x, y)
+          x + y
+        end
+      end
+      """
+    And a file named "spec/calculator_1_spec.rb" with:
+      """ruby
+      require 'calculator'
+
+      RSpec.describe "Calculator" do
+        it 'adds numbers' do
+          expect(Calculator.add(1, 2)).to eq(3)
+        end
+      end
+      """
+    And files "spec/calculator_2_spec.rb" through "spec/calculator_9_spec.rb" with an unrelated passing spec in each file
+    And a file named "spec/calculator_10_spec.rb" with:
+      """ruby
+      require 'calculator'
+
+      RSpec.describe "Monkey patched Calculator" do
+        it 'does screwy math' do
+          # monkey patching `Calculator` affects examples that are
+          # executed after this one!
+          def Calculator.add(x, y)
+            x - y
+          end
+
+          expect(Calculator.add(5, 10)).to eq(-5)
+        end
+      end
+      """
+    When I run `rspec --seed 1234`
+    Then the output should contain "10 examples, 1 failure"
+    When I run `rspec --seed 1234 --bisect`
+    Then the output should contain "rspec ./spec/calculator_10_spec.rb[1:1] ./spec/calculator_1_spec.rb[1:1] --seed 1234"
+    When I run `rspec ./spec/calculator_10_spec.rb[1:1] ./spec/calculator_1_spec.rb[1:1] --seed 1234`

Subject: [PATCH 137/258] When bisecting, exit each run as soon as possible.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8

- When an expected failure passes (or is pending)
  we don’t care about any other results.
- When the last expected failure finishes, we don’t
  care about any later examples.

I have no idea why these pass on 1.9.3 but not on 2.1 on
AppVeyor.  It would be nice to get them to pass but
I don’t have access to a windows box and lack to the time
fix it now.

   RSpec's `--order random` and `--seed` options help surface flickering examples that only fail when one or more other examples are executed first. It can be very difficult to isolate the exact combination of examples that triggers the failure. The `--bisect` flag helps solve that problem.
 
-  Pass the `--bisect` option (in addition to `--seed` any other options) and RSpec will repeatedly run subsets of your suite in order to isolate the minimal set of examples that reproduce the failure.

This allows it to be loaded by the bisect runner but if
it’s loaded by other things it’ll notify by causing the
“minimizes stdlibs” spec to fail.

Subject: [PATCH 162/258] Remove slow spec that's not needed.

I wasn't sure that ENV vars would be propagated to spawned
process properly, but no logic was required to make that work.
I tried backticks and `system` as well and those also do
the right thing.

Given that, there's no need to keep this slow spec around.

Revert "Add spec demonstrating that ENV vars are propagated properly."

This reverts commit 45ed50c512c824ddf3cd87c0c69a2ffe964493f1.

   RSpec's `--order random` and `--seed` options help surface flickering examples that only fail when one or more other examples are executed first. It can be very difficult to isolate the exact combination of examples that triggers the failure. The `--bisect` flag helps solve that problem.

Subject: [PATCH 172/258] Make specs from #1935 more robust.

- Ensure the specified behavior applies to nested
  groups and not simply top-level groups. The existing
  specs would have passed if the implementation of
  `configure_existing_groups` wrongly used
  `RSpec.world.example_groups` instead of
  `RSpec.world.all_example_groups`. This guards against that.
- Ensure metadata-based `include`/`extend`/`prepend` applies
  only to matching example groups. The existing specs would pass
  even if the metadata check was removed from the implementation
  of `configure_existing_groups`.

Subject: [PATCH 176/258] `c.mock_framework = :foo` => `c.mock_with :foo`

Both work but the latter is the way we document the
config elsewhere, so it's worth standardizing here.

Subject: [PATCH 180/258] Allows user code to retain references to memoized
 helpers

Accomplish this by no longer clearing the example's ivars.

Fixes rspec/rspec-core#1921

Context
-------

* This pull request:
  https://github.com/rspec/rspec-core/pull/1950
* Originally clearing ivars due to memory leak:
  https://github.com/rspec/rspec-core/issues/321
* Threadsafe memoized helpers caused `__memoized` to stop lazily initializing:
  https://github.com/rspec/rspec-core/issues/321
* This caused it to be permawiped by by the resetting of the example's ivars:
  https://github.com/rspec/rspec-core/issues/1921

However, this patch tests the behaviour of the memory leak,
rather than its mechanics, which shows that it was fixed at some point.
So we simply remove that code.

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Remove unnecessary `Array#last` call.
- This version is threadsafe, whereas the prior
  version wasn’t.  Consider what would happen if
  another thread added an example to the `examples`
  array while this was happening: it would have returned
  a different example than the one created here. We don’t
  actually do any multithreading when examples are defined,
  and have no plans to do so, but it’s always nice to make
  things more threadsafe.

Subject: [PATCH 182/258] More helpful assertions on memory leak test

The test for a memory leak failed on CI
https://travis-ci.org/rspec/rspec-core/jobs/61159415,
saying "expected result to have changed to 0, but is now 1"

This updates it so that future failures will
tell us which one was not garbage collected.

See https://github.com/rspec/rspec-core/pull/1950#issuecomment-98784821
for more details.

Subject: [PATCH 188/258] Move exception formatting logic into its own class.

- Simplifies the notification classes.
- Provides something we can use to format multiple
  expectation failures packaged as a single exception
  for `aggregate_failures`.

Subject: [PATCH 193/258] Refactor: centralize exception presenter options.

We need to combine some of these cases (such
as when we get a `MultipleExpectationsNotMetError`
in a pending spec), and to do that we need to combine
the options, so having the options listed in the same
method is a stepping stone towards that.

+    * RSpec::Core provides much better failure output, adding code snippets and backtraces to the sub-failures, just like it does for any normal failure.
+    * RSpec::Core provides [metadata](../metadata/user-defined-metadata) integration for this feature. Each example that is tagged with `:aggregate_failures` will be wrapped in an `aggregate_failures` block. You can also use `config.define_derived_metadata` to apply this to every example automatically.
+
+  The metadata form is quite convenient, but may not work well for end-to-end tests that have multiple distinct steps. For example, consider a spec for an HTTP client workflow that (1) makes a request, (2) expects a redirect, (3) follows the redirect, and (4) expects a particular response.  You probably want the `expect(response.status).to be_between(300, 399)` expectation to immediately abort if it fails, because you can't perform the next step (following the redirect) if that is not satisfied. For these situations, we encourage you to use the `aggregate_failures` block form to wrap each set of expectations that represents a distinct step in the test workflow.

Subject: [PATCH 200/258] Remove `:in ...` portion of backtrace lines from
 example output.

- The presence of backticks within that part was causing rendering
  problems on relish.
- Different rubies have different output there so we already ignore
  that part when comparing the expected to actual output.

Subject: [PATCH 206/258] Run GC multiple times if necessary

As suggested in https://github.com/rspec/rspec-core/pull/1950#issuecomment-99492550
Still leaves the conditional in, b/c Rbx didn't collect all the instances in my trial,
and JRuby wouldn't iterate over ObjectSpace.

Subject: [PATCH 207/258] Use :rerun_file_path when checking location filters

Fixes #1961

The problem with using :absolute_file_path is that it doesn't function
correctly for shared examples in an external file. The filter manager thinks
that there are no location filters set, when actually there are. Since
MetadataFilter already handles location filtering correctly across multiple
nested examples / files, correcting the path that is checked is sufficient to
fix the line filtering issue.

Subject: [PATCH 212/258] Make backtrace truncation much more robust.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is necessary for the changes in rspec/rspec-support#210.

That adds an additional stack frame to the parent exception
(for the lambda that wraps `raise`) and our truncation wasn’t
working properly with it. Really, the old way just happened to
work. This is much more robust.

Subject: [PATCH 233/258] Improve handling of additional `around`/`after`
 exceptions.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Now that we have nice formatting logic for multiple
exception errors, let’s leverage that to improve the
output for this case.

Fixes #1966.

Subject: [PATCH 236/258] Always verify mocks at the end of each example.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

...even if the example has already failed.

Previously, we did not have a good way to display
multiple failures for a single example, but we
do now, so it’s simpler and more consistent to
always verify, and to provide the user with multiple
exceptions if there are multiple.

Subject: [PATCH 237/258] Add `add` method to
 `RSpec::Expectations::MultipleExpectationsNotMetError`.

It's a little weird ot add it from rspec-core, but we only need it here
and this allows us to provide a common implementation.

For some reason, this failed on Travis:

I’m hoping that increasing it will prevent it from
failing again.

Subject: [PATCH 250/258] Revert "Always verify mocks at the end of each
 example."

This reverts commit f989168c9dbbcd930af6e7cc61e08057194929a8.

This is necessary to avoid the issue discussed in rspec/rspec-mocks#203.
I'm reverting it so we can release 3.3. We may bring this back for
3.4 if we can find a better solution.

Subject: [PATCH 254/258] Use shared example group like it looks like it was
 intended.

This shared group was only included at one place in
this file but it looks like there were two intended
inclusions.  This fixes that.

Subject: [PATCH 255/258] Fix group profile output regressions introduced in
 #1971.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Regressions fixed by this commit:

- We only considered top-level groups before, but #1971
  made it consider nested groups as well.  However, the
  example count was only incremented on the top-level
  group, which meant the output said “Inf seconds”
  since `float / 0` returns `Infinity`.
- We were wrongly listing the example group class name
  rather than the location. This is because we changed from
  locations to groups in the hash.

Fixes #1989.

Subject: [PATCH 256/258] Fix flickering test.

Profile example group ordering no longer relies on `example.clock`.
It relies directly on `RSpec::Core::Time.now` so we have to update
the spec to make it consistent.
