Bootsnap precomputes load path resolution and caches ruby ISeq
and YAML parsing/compilation, reducing application boot time by
approximately 50% on supported configurations.
The test using mathn was first introduced in f1d9179 to check that the
`distance_of_time_in_words` properly doesn't use the `Fixnum#/` method
by explicitly requiring this library as it redefines this method.
Given that `mathn` has been gemified in Ruby 2.5 and is deprecated since
version 2.2, we can certainly safely assume that people will most-likely
not require this library in their application.
However, to make sure that we don't regress, let's add a test similar to
the one before f1d9179.
Capybara was updated in teamcapybara/capybara#1841 to use Minitest style
assertions so that system test output shows x number of assertions, x
numbe of failures, etc.
Before:
```
6 runs, 0 assertions, 0 failures, 0 errors, 0 skips
```
After:
```
6 runs, 7 assertions, 1 failures, 0 errors, 0 skips
```
This change bumps Capybara from 2.7.0 to 2.13.0 and includes the
required minitest assertion file in the test case. 🎉
* Move system tests back into Action Pack
* Rename `ActionSystemTest` to `ActionDispatch::SystemTestCase`
* Remove private base module and only make file for public
`SystemTestCase` class, name private module `SystemTesting`
* Rename `ActionSystemTestCase` to `ApplicationSystemTestCase`
* Update corresponding documentation and guides
* Delete old `ActionSystemTest` files
Erubi offers the following advantages for Rails:
* Works with ruby's --enable-frozen-string-literal option
* Has 88% smaller memory footprint
* Does no freedom patching (Erubis adds a method to Kernel)
* Has simpler internals (1 file, <150 lines of code)
* Has an open development model (Erubis doesn't have a
public source control repository or bug tracker)
* Is not dead (Erubis hasn't been updated since 2011)
Erubi is a simplified fork of Erubis that contains just the
parts that are generally needed (which includes the parts
that Rails uses). The only intentional difference in
behavior is that it does not include support for <%=== tags
for debug output. That could be added to the ActionView ERB
handler if it is desired.
The Erubis template handler remains in a deprecated state
so that code that accesses it directly does not break. It
can be removed after Rails 5.1.
When the initial evented monitor feature was written, the latest version of listen
was the 3.0.x series. Since then the listen project has moved on to the 3.1.x series.
This patch allows the use of the new versions.
Mostly, this is just to avoid EventMachine. But there's also an argument
to be made that we're better off using a different protocol library for
our test suite than the one we use to implement the server.
