From 75924c4517c8f87712d3f59c11f10152ed57b9d8 Mon Sep 17 00:00:00 2001 From: Andrew White Date: Mon, 27 Feb 2017 18:31:35 +0000 Subject: Deprecate implicit coercion of `ActiveSupport::Duration` 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. --- activesupport/lib/active_support/cache/mem_cache_store.rb | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'activesupport/lib/active_support/cache') diff --git a/activesupport/lib/active_support/cache/mem_cache_store.rb b/activesupport/lib/active_support/cache/mem_cache_store.rb index e09cee3335..5eee04a34e 100644 --- a/activesupport/lib/active_support/cache/mem_cache_store.rb +++ b/activesupport/lib/active_support/cache/mem_cache_store.rb @@ -156,7 +156,7 @@ module ActiveSupport expires_in = options[:expires_in].to_i if expires_in > 0 && !options[:raw] # Set the memcache expire a few minutes in the future to support race condition ttls on read - expires_in += 5.minutes + expires_in += 300 end rescue_error_with false do @data.send(method, key, value, expires_in, options) -- cgit v1.2.3
