* Since weeks are no longer converted to days, add `:weeks` to the list of
parts that `ActiveSupport::TimeWithZone` will recognize as possibly being
of variable duration to take account of DST transitions.
Fixes #26039.
*Andrew White*
* Defines `Regexp.match?` for Ruby versions prior to 2.4. The predicate
has the same interface, but it does not have the performance boost. Its
purpose is to be able to write 2.4 compatible code.
*Xavier Noria*
* Allow MessageEncryptor to take advantage of authenticated encryption modes.
AEAD modes like `aes-256-gcm` provide both confidentiality and data
authenticity, eliminating the need to use MessageVerifier to check if the
encrypted data has been tampered with. This speeds up encryption/decryption
and results in shorter cipher text.
*Bart de Water*
* Introduce `assert_changes` and `assert_no_changes`.
`assert_changes` is a more general `assert_difference` that works with any
value.
assert_changes 'Error.current', from: nil, to: 'ERR' do
expected_bad_operation
end
Can be called with strings, to be evaluated in the binding (context) of
the block given to the assertion, or a lambda.
assert_changes -> { Error.current }, from: nil, to: 'ERR' do
expected_bad_operation
end
The `from` and `to` arguments are compared with the case operator (`===`).
assert_changes 'Error.current', from: nil, to: Error do
expected_bad_operation
end
This is pretty useful, if you need to loosely compare a value. For example,
you need to test a token has been generated and it has that many random
characters.
user = User.start_registration
assert_changes 'user.token', to: /\w{32}/ do
user.finish_registration
end
*Genadi Samokovarov*
* Add `:fallback_string` option to `Array#to_sentence`. If an empty array
calls the function and a fallback string option is set then it returns the
fallback string other than an empty string.
*Mohamed Osama*
* Fix `ActiveSupport::TimeZone#strptime`. Now raises `ArgumentError` when the
given time doesn't match the format. The error is the same as the one given
by Ruby's `Date.strptime`. Previously it raised
`NoMethodError: undefined method empty? for nil:NilClass.` due to a bug.
Fixes #25701.
*John Gesimondo*
* `travel/travel_to` travel time helpers, now raise on nested calls,
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 2.days do
# 2 days from today
end
travel 5.days do
# 5 days from today
end
*Vipul A M*
* Support parsing JSON time in ISO8601 local time strings in
`ActiveSupport::JSON.decode` when `parse_json_times` is enabled.
Strings in the format of `YYYY-MM-DD hh:mm:ss` (without a `Z` at
the end) will be parsed in the local timezone (`Time.zone`). In
addition, date strings (`YYYY-MM-DD`) are now parsed into `Date`
objects.
*Grzegorz Witek*
* Fixed `ActiveSupport::Logger.broadcast` so that calls to `#silence` now
properly delegate to all loggers. Silencing now properly suppresses logging
to both the log and the console.
*Kevin McPhillips*
* Remove deprecated arguments in `assert_nothing_raised`.
*Rafel Mendonça França*
* `Date.to_s` doesn't produce too many spaces. For example, `to_s(:short)`
will now produce `01 Feb` instead of ` 1 Feb`.
Fixes #25251.
*Sean Griffin*
* Introduce Module#delegate_missing_to.
When building a decorator, a common pattern emerges:
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
*Genadi Samokovarov*, *DHH*
* Rescuable: If a handler doesn't match the exception, check for handlers
matching the exception's cause.
*Jeremy Daer*
