2020-07-04Fix non-numeric exclusive Range#minmax bugSam Bostock
The implementation of Range#minmax added in d5c60214c45 causes the following incorrect behaviour: ('a'...'c').minmax => ["a", ["a", "b"]] instead of ('a'...'c').minmax => ["a", "b"] This is because the C implementation of Range#minmax (range_minmax) directly delegates to the C implementation of Range#min (range_min) and Range#max (range_max), without changing the execution context. Range#max's C implementation (range_max), when given a non-numeric exclusive range, delegates to super, which is meant to call Enumerable#max. However, because range_max is called directly by range_minmax, super calls Enumerable#minmax instead, causing the incorrect nesting. Perhaps it is possible to change the execution context in an optimized manner, but the simplest solution seems to be to just explicitly delegate from Range#minmax to Range#min and Range#max.

2019-11-18Deprecate taint/trust and related methods, and make the methods no-opsJeremy Evans
This removes the related tests, and puts the related specs behind version guards. This affects all code in lib, including some libraries that may want to support older versions of Ruby. Notes: Merged: https://github.com/ruby/ruby/pull/2476

2019-08-14Make Range#=== operate like cover? instead of include? for string rangesJeremy Evans
Previously, Range#=== treated string ranges that were not endless or beginless the same as include?, instead of the same as cover?. I think this was an oversight in 989e07c0f2fa664a54e52a475c2fcc145f06539d, as the commit message did not indicate this behavior was desired. This also makes some previously dead code no longer dead. Previously, the conditionals were doing this: if (RB_TYPE_P(beg, T_STRING) if (NIL_P(beg)) # can never be true This restructures it so at the NIL_P(beg) check, beg could possibly be nil (beginless ranges). Fixes [Bug #15449]
2019-08-14Implement Range#minmaxJeremy Evans
Range#minmax was previous not implemented, so calling #minmax on range was actually calling Enumerable#minmax. This is a simple implementation of #minmax by just calling range_min and range_max. Fixes [Bug #15867] Fixes [Bug #15807]

2018-08-06enumerator.c: Introduce Enumerator::ArithmeticSequencemrkn
This commit introduces new core class Enumerator::ArithmeticSequence. Enumerator::ArithmeticSequence is a subclass of Enumerator, and represents a number generator of an arithmetic sequence. After this commit, Numeric#step and Range#step without blocks returned an ArithmeticSequence object instead of an Enumerator. This class introduces the following incompatibilities: - You can create a zero-step ArithmeticSequence, and its size is not ArgumentError, but Infinity. - You can create a negative-step ArithmeticSequence from a range.
