From c85e3f65f3409fc329732912908c3601d8e5fac9 Mon Sep 17 00:00:00 2001 From: Edouard CHIN Date: Tue, 9 Oct 2018 13:36:56 -0400 Subject: [PATCH] Fix issue where duration where always rounded up to a second: - Adding a Float as a duration to a datetime would result in the Float being rounded. Doing something like would have no effect because the 0.45 seconds would be rounded to 0 second. ```ruby time = DateTime.parse("2018-1-1") time += 0.45.seconds ``` This behavior was intentionally added a very long time ago, the reason was because Ruby 1.8 was using `Integer#gcd` in the constructor of Rational which didn't accept a float value. That's no longer the case and doing `Rational(0.45, 86400)` would now perfectly work fine. - Fixes #34008 --- activesupport/CHANGELOG.md | 9 +++++++++ .../active_support/core_ext/date_time/calculations.rb | 2 +- activesupport/test/core_ext/date_time_ext_test.rb | 4 ++-- 3 files changed, 12 insertions(+), 3 deletions(-) diff --git a/activesupport/CHANGELOG.md b/activesupport/CHANGELOG.md index 2e465a0310..2f5ed35f46 100644 --- a/activesupport/CHANGELOG.md +++ b/activesupport/CHANGELOG.md @@ -1,3 +1,12 @@ +* Fix duration being rounded to a full second. + ``` + time = DateTime.parse("2018-1-1") + time += 0.51.seconds + ``` + Will now correctly add 0.51 second and not 1 full second. + + *Edouard Chin* + * Deprecate `ActiveSupport::Multibyte::Unicode#normalize` and `ActiveSuppport::Multibyte::Chars#normalize` in favor of `String#unicode_normalize` diff --git a/activesupport/lib/active_support/core_ext/date_time/calculations.rb b/activesupport/lib/active_support/core_ext/date_time/calculations.rb index e61b23f842..bc670c3e76 100644 --- a/activesupport/lib/active_support/core_ext/date_time/calculations.rb +++ b/activesupport/lib/active_support/core_ext/date_time/calculations.rb @@ -110,7 +110,7 @@ def ago(seconds) # instance time.
