Since Rails 6.0 will support Ruby 2.4.1 or higher
`# frozen_string_literal: true` magic comment is enough to make string object frozen.
This magic comment is enabled by `Style/FrozenStringLiteralComment` cop.
* Exclude these files not to auto correct false positive `Regexp#freeze`
- 'actionpack/lib/action_dispatch/journey/router/utils.rb'
- 'activerecord/lib/active_record/connection_adapters/sqlite3_adapter.rb'
It has been fixed by https://github.com/rubocop-hq/rubocop/pull/6333
Once the newer version of RuboCop released and available at Code Climate these exclude entries should be removed.
* Replace `String#freeze` with `String#-@` manually if explicit frozen string objects are required
- 'actionpack/test/controller/test_case_test.rb'
- 'activemodel/test/cases/type/string_test.rb'
- 'activesupport/lib/active_support/core_ext/string/strip.rb'
- 'activesupport/test/core_ext/string_ext_test.rb'

In Ruby 2.3 or later, `String#+@` is available and `+@` is faster than `dup`.
```ruby
# frozen_string_literal: true
require "bundler/inline"
gemfile(true) do
source "https://rubygems.org"
gem "benchmark-ips"
end
Benchmark.ips do |x|
x.report('+@') { +"" }
x.report('dup') { "".dup }
x.compare!
end
```
```

The method removes and returns the elements for which the block returns a true value.
If no block is given, an Enumerator is returned instead.
```
numbers = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
odd_numbers = numbers.extract! { |number| number.odd? } # => [1, 3, 5, 7, 9]
numbers # => [0, 2, 4, 6, 8]

- There was an issue inside controller tests where order params were not respected, the reason
was because we were calling `Hash#to_query` which sorts the results lexicographically.
1e4e1b62 fixed that issue by not using `to_query` but instead a utility function provided by rack.
- However with the fix came another issue where it's now no longer possible to do this
```
post :foo, params: { user: User.first }
# Prior to the patch the controller will receive { "user" => "1" }
# Whereas now you get { "user": "#<User: ...>" }
```
The fix in this PR is to modify `Hash#to_query` to sort only when it
doesn't contain an array structure that looks something like "bar[]"

When multiplying or dividing a duration by a scalar, it's tempting to
operate directly on the duration's value in seconds and recompute the
parts from the result. However this loses information, as there are
multiple combinations of parts that map to any given number of seconds
(e.g. `2.weeks` or `336.hours`). This is especially problematic when
dealing with durations on the scale of months or years, as converting an
exact number of seconds to one of those intervals and then using the
resulting duration to modify a date will give the wrong result.

In the app I'm working on I've wished that index_by had a buddy that would
assign the hash value instead of the key multiple times.
Enter index_with. Useful when building a hash from a static list of
symbols. Before you'd do:
```ruby
POST_ATTRIBUTES.map { |attr_name| [ attr_name, public_send(attr_name) ] }.to_h
```
But now that's a little clearer and faster with:
````ruby
POST_ATTRIBUTES.index_with { |attr_name| public_send(attr_name) }
```
It's also useful when you have an enumerable that should be converted to a hash,
but you don't want to muddle the code up with the overhead that it takes to create
that hash. So before, that's:
```ruby
WEEKDAYS.each_with_object(Hash.new) do |day, intervals|
intervals[day] = [ Interval.all_day ]
end
```
And now it's just:
```ruby
WEEKDAYS.index_with([ Interval.all_day ])
```
It's also nice to quickly get a hash with either nil, [], or {} as the value.

See #29632 for details. In short, it's possible to enter `LoadError#is_missing?` when `LoadError#path` returns `nil`, leading to `path.sub` throwing an none-to-helpful `NoMethodError`.
This tiniest of patch inserts `#to_s` before the `sub` call to make sure it succeeds. Affected surface area should be just as tiny since something has already gone wrong to get us into `#is_missing?` and the current behavior when `#path` returns `nil` seems clearly not intended.

Add `before?` and `after?` methods to date and time classes
|
| |
| |
| |
| |
| |
| |
| |
| | |
Equality comparisons between dates and times can take some extra time to
comprehend. I tend to think of a date or time as "before" or "after"
another date or time, but I naturally read `<` and `>` as "less than"
and "greater than." This change seeks to make date/time comparisons more
human readable.

Previously, URI.enscape could handle Unicode input (without any actual
escaped characters), or input with escaped characters (but no actual
Unicode characters) - not both.
URI.unescape("\xe3\x83\x90") # => "バ"
URI.unescape("%E3%83%90") # => "バ"
URI.unescape("\xe3\x83\x90%E3%83%90") # =>
# Encoding::CompatibilityError
We need to let `gsub` handle this for us, and then force back to the
original encoding of the input. The result String will be mangled if
the percent-encoded characters don't conform to the encoding of the
String itself, but that goes without saying.

Numeric#positive? and Numeric#negative? was added to Ruby since 2.3,
see https://github.com/ruby/ruby/blob/ruby_2_3/NEWS
Rails 6 requires Ruby 2.4.1+ since https://github.com/rails/rails/pull/32034
|
|
|
|
|

Ruby 2.4+ provides `Hash#compact` and `Hash#compact!` natively,
so `active_support/core_ext/hash/compact` is no longer necessary.

Some places we can't remove because Ruby still don't have a method
equivalent to strip_heredoc to be called in an already existent string.

Add support for multiple encodings in String.blank?

Motivation:
- When strings are encoded with `.encode("UTF-16LE")` `.blank?` throws
an `Encoding::CompatibilityError` exception.
- We tested multiple implementation to see what the fastest
implementation was, rescueing the execption seems to be the fastest
option we could find.
Related Issues:
- #28953
Changes:
- Add a rescue to catch the exception.
- Added a `Concurrent::Map` to store a cache of encoded regex objects
for requested encoding types.
- Use the new `Concurrent::Map` cache to return the correct regex for
the string being checked.

This pull request handles `FrozenError` introduced by Ruby 2.5.
Refer https://bugs.ruby-lang.org/projects/ruby-trunk/repository/revisions/61131
Since `FrozenError` is a subclass of `RuntimeError` minitest used by master
branch can handle it, though it would be better to handle `FrozenError`
explicitly if possible.
`FrozenError` does not exist in Ruby 2.4 or lower, `frozen_error_class`
handles which exception is expected to be raised.
This pull request is intended to be merged to master,
then backported to `5-1-stable` to address #31508

These methods were originally added in https://github.com/rails/rails/pull/26600
This includes a couple of refactors to make these methods behave more similarly to other Date/Time extensions added by Active Support:
1. Use `advance` instead of `since` and `ago` to time-travel — this is particularly important to keep the returned instance’s class matching `self`. Before this change:
today = Date.today # => Tue, 28 Nov 2017
today.class # => Date
today.next_occurring(:wednesday) # => Wed, 29 Nov 2017 00:00:00 UTC +00:00
today.next_occurring(:wednesday).class # => ActiveSupport::TimeWithZone
After this change, a Date (or Time, or DateTime) instance is properly returned (just like is shown in the new docs). This is generally how everything else in DateAndTime::Calculations works.
2. Move the tests from the DateTime tests to the DateAndTimeBehavior tests. The latter location is mixed in to the core_ext tests for _all_ of Date, Time, and DateTime to test the behavior across all of the classes. The previous location is for testing core_ext functionality added specifically just to DateTime.
3. Better docs!

Make `ActiveSupport::TimeWithZone` match Ruby's handling of ambiguous
times by choosing the later period, e.g.
Ruby:
```
ENV["TZ"] = "Europe/Moscow"
Time.local(2014, 10, 26, 1, 0, 0) # => 2014-10-26 01:00:00 +0300
```
Before:
```
>> "2014-10-26 01:00:00".in_time_zone("Moscow")
TZInfo::AmbiguousTime: 26/10/2014 01:00 is an ambiguous local time.
```
After:
```
>> "2014-10-26 01:00:00".in_time_zone("Moscow")
=> Sun, 26 Oct 2014 01:00:00 MSK +03:00
```
Fixes #17395.
