* Add missing support for modulo operations on durationsSayan Chakraborty2017-07-281-1/+47
| | | | | | | | | | | Rails 5.1 introduce an `ActiveSupport::Duration::Scalar` class as a wrapper around a numeric value as a way of ensuring a duration was the outcome of an expression. However the implementation was missing support for modulo operations. This commit adds support for those operations and should result in a duration being returned from expressions involving them. Fixes #29603 and #29743.
* Fix division where a duration is the denominatorAndrew White2017-07-271-5/+4
| | | | | | | | | PR #29163 introduced a change in behavior when a duration was the denominator in a calculation - this was incorrect as dividing by a duration should always return a `Numeric`. The behavior of previous versions of Rails has been restored. Fixes #29592.

* Fix implicit calculations with scalars and durationsAndrew White2017-05-201-6/+35
| | | | | | | | | | | | | | | | | | | | | Previously calculations where the scalar is first would be converted to a duration of seconds but this causes issues with dates being converted to times, e.g: Time.zone = "Beijing" # => Asia/Shanghai date = Date.civil(2017, 5, 20) # => Mon, 20 May 2017 2 * 1.day # => 172800 seconds date + 2 * 1.day # => Mon, 22 May 2017 00:00:00 CST +08:00 Now the `ActiveSupport::Duration::Scalar` calculation methods will try to maintain the part structure of the duration where possible, e.g: Time.zone = "Beijing" # => Asia/Shanghai date = Date.civil(2017, 5, 20) # => Mon, 20 May 2017 2 * 1.day # => 2 days date + 2 * 1.day # => Mon, 22 May 2017 Fixes #29160, #28970.
* `respond_to_missing?` should be privateRyuta Kamizono2017-04-221-5/+5
| | | | | | | Follow up of 03d3f036. Some of `respond_to?` were replaced to `respond_to_missing?` in 03d3f036. But the visibility is still public. It should be private.
* Remove implicit coercion deprecation of durationsAndrew White2017-03-151-10/+78
| | | | | | | | | | | | | | | | In #28204 we deprecated implicit conversion of durations to a numeric which represented the number of seconds in the duration because of unwanted side effects with calculations on durations and dates. This unfortunately had the side effect of forcing a explicit cast when configuring third-party libraries like expiration in Redis, e.g: redis.expire("foo", 5.minutes) To work around this we've removed the deprecation and added a private class that wraps the numeric and can perform calculation involving durations and ensure that they remain a duration irrespective of the order of operations.

* Deprecate implicit coercion of `ActiveSupport::Duration`Andrew White2017-03-021-2/+39
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently `ActiveSupport::Duration` implicitly converts to a seconds value when used in a calculation except for the explicit examples of addition and subtraction where the duration is the receiver, e.g: >> 2 * 1.day => 172800 This results in lots of confusion especially when using durations with dates because adding/subtracting a value from a date treats integers as a day and not a second, e.g: >> Date.today => Wed, 01 Mar 2017 >> Date.today + 2 * 1.day => Mon, 10 Apr 2490 To fix this we're implementing `coerce` so that we can provide a deprecation warning with the intent of removing the implicit coercion in Rails 5.2, e.g: >> 2 * 1.day DEPRECATION WARNING: Implicit coercion of ActiveSupport::Duration to a Numeric is deprecated and will raise a TypeError in Rails 5.2. => 172800 In Rails 5.2 it will raise `TypeError`, e.g: >> 2 * 1.day TypeError: ActiveSupport::Duration can't be coerced into Integer This is the same behavior as with other types in Ruby, e.g: >> 2 * "foo" TypeError: String can't be coerced into Integer >> "foo" * 2 => "foofoo" As part of this deprecation add `*` and `/` methods to `AS::Duration` so that calculations that keep the duration as the receiver work correctly whether the final receiver is a `Date` or `Time`, e.g: >> Date.today => Wed, 01 Mar 2017 >> Date.today + 1.day * 2 => Fri, 03 Mar 2017 Fixes #27457.
* Add Duration#before and #after as aliases for #ago and #sinceNick Johnstone2017-02-261-0/+2
| | | | | | | | | | | | | | It's common in test cases at my job to have code like this: let(:today) { customer_start_date + 2.weeks } let(:earlier_date) { today - 5.days } With this change, we can instead write let(:today) { 2.weeks.after(customer_start_date) } let(:earlier_date) { 5.days.before(today) } Closes #27721
* Add duration constructors for use in Numeric extensionsAndrew White2017-01-121-26/+68
| | | | | The Numeric extensions like 1.day, 1.month, etc. shouldn't know how the internals of ActiveSupport::Duration works.
* Fix inconsistent results when parsing large durations and constructing ↵Andrey Novikov2017-01-091-8/+19
| | | | | | | | | | | | | | | | | | | | | | | | | durations from code ActiveSupport::Duration.parse('P3Y') == 3.years # It should be true Duration parsing made independent from any moment of time: Fixed length in seconds is assigned to each duration part during parsing. Changed duration of months and years in seconds to more accurate and logical: 1. The value of 365.2425 days in Gregorian year is more accurate as it accounts for every 400th non-leap year. 2. Month's length is bound to year's duration, which makes sensible comparisons like `12.months == 1.year` to be `true` and nonsensical ones like `30.days == 1.month` to be `false`. Calculations on times and dates with durations shouldn't be affected as duration's numeric value isn't used in calculations, only parts are used. Methods on `Numeric` like `2.days` now use these predefined durations to avoid duplicating of duration constants through the codebase and eliminate creation of intermediate durations.

* Treat combined durations as a single unitSean Griffin2016-11-291-3/+9
| | | | | | | | | | | | Prior to this commit, `3.months - 3.months` would result in a duration that has the "parts" of `[[:months, 3], [:months, -3]]`. This would mean that it was subtly different than `2.months - 2.months`. When applied to a time, the date might actually change if the resulting day doesn't exist however many months in the future, even though in both cases we just wanted to add `0`, which should always be an identity operation. With this change, we now store the parts as a hash, so `3.months - 3.months` is simply stored as `{ months: 0 }`.
* Ensure duration parsing is consistent across DST changesAndrew White2016-10-311-2/+3
| | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the following returns `false`, contrary to expectation: 1.minute.eql?(1.minute) Adding method `#eql?` will make this behave like expected. Method `#eql?` is just a bit stricter than `#==`, as it checks whether the argument is also a uration. Their parts may be different though. 1.minute.eql?(60.seconds) # => true 1.minute.eql?(60) # => false

* | Follow-up to #16560Robin Dupret2014-08-241-2/+2
| | | | | | | | | | | | | | For the sake of backward-compatibility, we need to make #instance_of? return true for Fixnum. On the other hand, the method should still give true for ActiveSupport::Duration itself which was not the case before.
* | Define the Duration#instance_of? methodRobin Dupret2014-08-181-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | Since Duration is extending from ProxyObject which extends itself from BasicObject, the Duration object doesn't respond to the #instance_of? method. Thus, the #method_missing hook get triggered, delegating the method to its `value` attribute. However, Rubinius' #eql? definition relies on #instance_of?, thus this will equal to true with a Fixnum (since its `value` attribute is a Fixnum) while it should not. The previous behavior was wrong anyway, no matter the implementation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes: 1.second.eql?(1.second) #=> false The new `eql?` requires that `other` is an `ActiveSupport::Duration`. This requirement makes `ActiveSupport::Duration`'s behavior consistent with other numeric types in Ruby. 1.eql?(1.0) #=> false 1.0.eql?(1) #=> false 1.second.eql?(1) #=> false (was true) 1.eql?(1.second) #=> false { 1 => "foo", 1.0 => "bar" } #=> { 1 => "foo", 1.0 => "bar" } { 1 => "foo", 1.second => "bar" } # now => { 1 => "foo", 1.second => "bar" } # was => { 1 => "bar" } And though the behavior here hasn't changed, for reference: 1 == 1.0 #=> true 1.0 == 1 #=> true 1 == 1.second #=> true 1.second == 1 #=> true
* | Fix segmentation fault in Ruby 2.0.0-p353.Dmitriy Kiriyenko2013-11-301-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | In Ruby 2.0.0-p353 there was a [commit](https://github.com/ruby/ruby/commit/66915c507777c5e3a978fa73de25db763efd9206) that switched case matching from actual sending `===` method to magic lookup, that does not see it in `method_missing`. It's hard to predict how exactly and when exactly this bug will be solved so here I suggest a solution of defining it in Duration directly. In Ruby 2.0.0-p353 without the added fix added test crashes to segmentation fault.

Can't win 'em all :) Rationale: * no name conflict between local var and attr_accessor * no reassignment of local var * algorithm spelled out in steps * unused items in initial list filtered out early * empty-list case handled early instead of reassigning local var * no duplication of formatting strings ("0 seconds") Benchmarks (after PR #11855 merged): 10000.times do 1.second.inspect end original #inspect 0.350000 0.000000 0.350000 ( 0.354709) 0.330000 0.000000 0.330000 ( 0.331885) 0.330000 0.000000 0.330000 ( 0.334441) refactored #inspect 0.340000 0.000000 0.340000 ( 0.340080) 0.340000 0.010000 0.350000 ( 0.345069) 0.330000 0.000000 0.330000 ( 0.335873) 10000.times do (1.day + 1.month + 2.minutes + 1.day).inspect end original #inspect 0.400000 0.000000 0.400000 ( 0.403027) 0.400000 0.000000 0.400000 ( 0.403781) 0.390000 0.000000 0.390000 ( 0.387596) refactored #inspect 0.400000 0.010000 0.410000 ( 0.399792) 0.400000 0.000000 0.400000 ( 0.404145) 0.400000 0.000000 0.400000 ( 0.403820)
