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 modulo operations involving durations
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 support has now been added and should result in a duration being returned from expressions involving modulo operations.Prior to Rails 5.1:
5.minutes % 2.minutes => 60
Now:
5.minutes % 2.minutes => 1 minute
Fixes #29603 and #29743.

Fix division where a duration is the denominator
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.

Add purpose and expiry support to
ActiveSupport::MessageVerifier
&ActiveSupport::MessageEncryptor
.For instance, to ensure a message is only usable for one intended purpose:
token = @verifier.generate("x", purpose: :shipping) @verifier.verified(token, purpose: :shipping) # => "x" @verifier.verified(token) # => nil
Or make it expire after a set time:
@verifier.generate("x", expires_in: 1.month) @verifier.generate("y", expires_at: Time.now.end_of_year)
Showcased with
ActiveSupport::MessageVerifier
, but works the same forActiveSupport::MessageEncryptor

Cache:
write_multi
Rails.cache.write_multi foo: 'bar', baz: 'qux'
Plus faster fetch_multi with stores that implement
write_multi_entries
. Keys that aren't found may be written to the cache store in one shot instead of separate writes.The default implementation simply calls
write_entry
for each entry. Stores may override if they're capable of one-shot bulk writes, like RedisMSET

Fix implicit coercion calculations with scalars and durations
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.

Add support for versioned cache entries. This enables the cache stores to recycle cache keys, greatly saving on storage in cases with frequent churn. Works together with the separation of
#cache_key
and#cache_version
in Active Record and its use in Action Pack's fragment caching.DHH
