Previously `ActiveSupport::Duration.parse` used `Time.current` and
`Time#advance` to calculate the number of seconds in the duration
from an arbitrary collection of parts. However as `advance` tries to
be consistent across DST boundaries this meant that either the
duration was shorter or longer depending on the time of year.
This was fixed by using an absolute reference point in UTC which
isn't subject to DST transitions. An arbitrary date of Jan 1st, 2000
was chosen for no other reason that it seemed appropriate.
Additionally, duration parsing should now be marginally faster as we
are no longer creating instances of `ActiveSupport::TimeWithZone`
every time we parse a duration string.
Fixes #26941.

- Ruby 2.4 has added Hash#compact and Hash#compact! so we can use it
now.

`copy_time_to` is a helper function for date and time calculations.
It's being used by `prev_week`, `next_week` and `prev_weekday` to keep
the time fraction when jumping around between days.
Previously the nanoseconds part was lost during the operation. This
lead to problems in practice if you were using the `end_of_day`
calculation. Resulting in the time fraction of `end_of_day` not being
the same as next week's `end_of_day`.
With this fix `copy_time_to` doesn't forget the `nsec` digits.

Turns out trying to cache on localtime with arguments is too hard
so we'll do it on DateAndTime::Compatibility#to_time instead.
This reverts commit 9ce2d1b1a43fc4ef3db59849b7412d30583a4074, reversing

Previously memoization in `localtime` wasn't taking the `utc_offset`
parameter into account when returning a cached value. It now caches the
computed value depending on the `utc_offset` parameter, e.g:
Time.zone = "US/Eastern"
t = Time.zone.local(2016,5,2,11)
# => Mon, 02 May 2016 11:00:00 EDT -04:00
t.localtime(-7200)
# => 2016-05-02 13:00:00 -0200
t.localtime(-3600)
# => 2016-05-02 14:00:00 -0100

Previously calls to `in` were being sent to the non-DST aware
method `Time#since` via `method_missing`. It is now aliased to
the DST aware `ActiveSupport::TimeWithZone#+` which handles
transitions across DST boundaries, e.g:
Time.zone = "US/Eastern"
t = Time.zone.local(2016,11,6,1)
# => Sun, 06 Nov 2016 01:00:00 EDT -05:00
t.in(1.hour)
# => Sun, 06 Nov 2016 01:00:00 EST -05:00

The current implementation of `thread_mattr_accessor` set variable
sharing superclass with subclass. So the method doesn't work as documented.
Precondition
class Account
thread_mattr_accessor :user
end
class Customer < Account
end
Account.user = "DHH"
Account.user #=> "DHH"
Customer.user = "Rafael"
Customer.user # => "Rafael"
Documented behavior
Account.user # => "DHH"
Actual behavior
Account.user # => "Rafael"
Current implementation set variable statically likes `Thread[:attr_Account_user]`,
and customer also use it.
Make variable name dynamic to use own thread-local variable.

Since 434df00 week durations are no longer converted to days. This means
we need to add :weeks to the parts that ActiveSupport::TimeWithZone will
consider being of variable duration to take account of DST transitions.

Those are assertions that I really do miss from the standard
`ActiveSupport::TestCase`. Think of those as a more general version of
`assert_difference` and `assert_no_difference` (those can be implemented
by assert_changes, should this change be accepted).
Why do we need those? They are useful when you want to check a
side-effect of an operation. `assert_difference` do cover a really
common case, but we `assert_changes` gives us more control. Having a
global error flag? You can test it easily with `assert_changes`. In
fact, you can be really specific about the initial state and the
terminal one.
```ruby
error = Error.new(:bad)
assert_changes -> { Error.current }, from: nil, to: error do
expected_bad_operation
end
```
`assert_changes` follows `assert_difference` and a string can be given
for evaluation as well.
```ruby
error = Error.new(:bad)
assert_changes 'Error.current', from: nil, to: error do
expected_bad_operation
end
```
Check out the test cases if you wanna see more examples.

as this can lead to confusing time stubbing.
Instead of:
travel_to 2.days.from_now do
# 2 days from today
travel_to 3.days.from_now do
# 5 days from today
end
end
preferred way to achieve above is:
travel_to 2.days.from_now
# 2 days from today
travel_back
travel_to 5.days.from_now
# 5 days from today

Use correct timezone when parsing date in json

Fixes https://github.com/rails/rails/issues/22171
Time specified in ISO 8601 format without `Z` should be considered as local
time, yet until now it was treated as UTC.
This commit fixes problem by parsing time using timezone specified in
application config.
The downside of this solution is performance hit (`Time.zone.parse` is ~ 1.6x
slower than `Time.parse`), so maybe there's a better solution.

We are currently using `%e` which adds a space before the result if the
digit is a single number. This leads to strings like `February 2, 2016`
which is undesireable. I've opted to replace with 0 padding instead of
removing the padding entirely, to preserve compatibility for those
relying on the fact that the width is constant, and to be consistent
with time formatting.
Fixes #25251.

When building decorators, a common pattern may emerge:
class Partition
def initialize(first_event)
@events = [ first_event ]
end
def people
if @events.first.detail.people.any?
@events.collect { |e| Array(e.detail.people) }.flatten.uniq
else
@events.collect(&:creator).uniq
end
end
private
def respond_to_missing?(name, include_private = false)
@events.respond_to?(name, include_private)
end
def method_missing(method, *args, &block)
@events.send(method, *args, &block)
end
end
With `Module#delegate_missing_to`, the above is condensed to:
class Partition
delegate_missing_to :@events
def initialize(first_event)
@events = [ first_event ]
end
def people
if @events.first.detail.people.any?
@events.collect { |e| Array(e.detail.people) }.flatten.uniq
else
@events.collect(&:creator).uniq
end
end
end

Follows the same pattern as controllers and jobs. Exceptions raised in
delivery jobs (enqueued by `#deliver_later`) are also delegated to the
mailer's rescue_from handlers, so you can handle the DeserializationError
raised by delivery jobs:
```ruby
class MyMailer < ApplicationMailer
rescue_from ActiveJob::DeserializationError do
…
end
```
ActiveSupport::Rescuable polish:
* Add the `rescue_with_handler` class method so exceptions may be
handled at the class level without requiring an instance.
* Rationalize `exception.cause` handling. If no handler matches the
exception, fall back to the handler that matches its cause.
* Handle exceptions raised elsewhere. Pass `object: …` to execute
the `rescue_from` handler (e.g. a method call or a block to
instance_exec) against a different object. Defaults to `self`.

This can be an issue when TZInfo::TimeZone#current_period is refreshed
due to timezone period transition, but it's not reflected in
ActiveSupport::TimeZone object.
For example, on Sun, 26 Oct 2014 22:00 UTC, Moscow changed its TZ from
MSK +04:00 to MSK +03:00 (-1 hour). If ActiveSupport::TimeZone['Moscow']
happens to be initialized just before the timezone transition, it will
cache its stale utc_offset even after the timezone transition.
This commit removes cache and fixes this issue.

Previously these methods could return either a DateTime or a Time
depending on how the ActiveSupport::TimeWithZone instance had
been constructed. Changing to always return an instance of Time
eliminates a possible stack level too deep error in to_time where
it was wrapping a DateTime instance.
As a consequence of this the internal time value is now always an
instance of Time in the UTC timezone, whether that's as the UTC
time directly or a representation of the local time in the timezone.
There should be no consequences of this internal change and if
there are it's a bug due to leaky abstractions.

In Ruby 2.4 the `to_time` method for both `DateTime` and `Time` will
preserve the timezone of the receiver when converting to an instance
of `Time`. Since Rails 5.0 will support Ruby 2.2, 2.3 and later we
need to introduce a compatibility layer so that apps that upgrade do
not break. New apps will have a config initializer file that defaults
to match the new Ruby 2.4 behavior going forward.

Ruby 2.4 introduces `Array#sum`, but it only supports numeric elements,
breaking our `Enumerable#sum` which supports arbitrary `Object#+`.
To fix, override `Array#sum` with our compatible implementation.
Native Ruby 2.4:
%w[ a b ].sum
# => TypeError: String can't be coerced into Fixnum
With `Enumerable#sum` shim:
%w[ a b ].sum
# => 'ab'
We tried shimming the fast path and falling back to the compatible path
if it fails, but that ends up slower even in simple causes due to the cost
of exception handling. Our only choice is to override the native `Array#sum`
with our `Enumerable#sum`.
