We test the failing case we're trying to patch; only if it throws an
Exception do we patch.
Currently this will *always* throw, but upstream Ruby has patched this
bug: https://git.io/vAxKB

URI.unescape "extension" fails with Unicode input
|
| |
| |

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.

We have a bunch of documentation in
lib/active_support/core_ext/object/json.rb which is currently appearing
as documentation for the top-level ActiveSupport module. We hide it
from rdoc here.

Convert the user to atheism by ditching the extra example that demonstrates
the same thing as date_of_birth.
Demonstrate the NoMethodError on date_of_birth first, then call age that
uses date_of_birth internally. Thus showing that accessing it publicly fails,
but using it internally succeeds.

Numeric#positive? and Numeric#negative? was added to Ruby since 2.3,

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.

I noticed this in my memory profiler report.
```
153 "@default_url_options"
152 /home/sam/.rbenv/versions/2.5.0/lib/ruby/gems/2.5.0/gems/activesupport-5.1.4/lib/active_support/core_ext/class/attribute.rb:84
```
152 copies of the string `@default_url_options` are retained on the heap in Discourse post boot.
Since this is just used for ivar lookups there is no need to use a string.

### Summary
This PR changes .rubocop.yml.
Regarding the code using `if ... else ... end`, I think the coding style
that Rails expects is as follows.
```ruby
var = if cond
a
else
b
end
```
However, the current .rubocop.yml setting does not offense for the
following code.
```ruby
var = if cond
a
else
b
end
```
I think that the above code expects offense to be warned.
Moreover, the layout by autocorrect is unnatural.
```ruby
var = if cond
a
else
b
end
```
This PR adds a setting to .rubocop.yml to make an offense warning and
autocorrect as expected by the coding style.
And this change also fixes `case ... when ... end` together.
Also this PR itself is an example that arranges the layout using
`rubocop -a`.
### Other Information
Autocorrect of `Lint/EndAlignment` cop is `false` by default.
https://github.com/bbatsov/rubocop/blob/v0.51.0/config/default.yml#L1443
This PR changes this value to `true`.
Also this PR has changed it together as it is necessary to enable
`Layout/ElseAlignment` cop to make this behavior.

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.

`BigDecimal.new` has been deprecated in BigDecimal 1.3.3
which will be a default for Ruby 2.5.
Refer
https://github.com/ruby/bigdecimal/commit/533737338db915b00dc7168c3602e4b462b23503
* This commit has been made as follows:
```
cd rails
git grep -l BigDecimal.new | grep -v guides/source/5_0_release_notes.md | grep -v activesupport/test/xml_mini_test.rb | xargs sed -i -e "s/BigDecimal.new/BigDecimal/g"
```
- `activesupport/test/xml_mini_test.rb`
Editmanually to remove `.new` and `::`
- guides/source/5_0_release_notes.md
This is a Rails 5.0 release notes.

Example codes that use `has_many` or `before_create` in `Module::Concerning` look like active record models.
So I've made them inherit `ApplicationRecord`.

(#31275)

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!

In #11474 we prevented TWZ ranges being iterated over which matched
Ruby's handling of Time ranges and as a consequence `include?` stopped
working with both Time ranges and TWZ ranges. However in
ruby/ruby@b061634 support was added for `include?` to use `cover?` for
'linear' objects. Since we have no way of making Ruby consider TWZ
instances as 'linear' we have to override `Range#include?`.
Fixes #30799.

activesupport/lib/active_support/core_ext/object/acts_like.rb
acts_like?
Add a case statement to use direct symbols instead of string
interpolation for the three scenarios I found in the Rails codebase:
time, date, and string.
For time/date/string, this change prevents two string allocations for
each time the method is called and speeds up the method by ~2.7x. For
other arguments, there is no memory difference and performance
difference is within margin of error.

In order to keep this method compatible with the Ruby 2.5 version of Hash#slice.
This bahavior is actually slightly incompatibile with previous versions of Active Support
but it might not cause a real problem, since HWIA, the biggest use case of Hash subclassing here,
already overrides `slice` to return another HWIA.
