* Fix Range#cover? returning true for beginless ranges of different typesJeremy Evans2022-06-061-0/+29
| | | | | | | | | | | | | Previously `(2..).cover?("2"..)` was false, but `(..2).cover?(.."2")` was true. This changes it so both are false, treating beginless ranges the same as endless ranges in regards to type checks. This also adds documentation to #cover? to describe behavior with beginless and endless ranges, testing each documentation example, which is how this bug was found. Fixes [Bug #18155]
* Fix Range#include? for beginless exclusive string rangesJeremy Evans2022-02-091-0/+4
| | | | | | | | | Previously, include? would return true for the end of the range, when it should return false because the range is exclusive. Research and Analysis by Victor Shepelev. Fixes [Bug #18577]

* Special case Range#max for integer beginning and Float::Infinity endJeremy Evans2020-07-191-0/+6
| | | | | | | | | Popular Ruby libraries such as Rails and Rubocop relying on the previous behavior, even though it is technically a bug. The correct behavior is probably raising RangeError, since that is what an endless range raises. Related to [Bug #17017]
* Fix Range#max for beginless Integer ranges [Bug #17034]Michael Kohl2020-07-191-0/+4
| | | | | | | | | * Fix Range#max for beginless Integer ranges * Update test/ruby/test_range.rb * Fix formatting https://github.com/ruby/ruby/pull/3328 Co-authored-by: Nobuyoshi Nakada <nobu@ruby-lang.org>
* Fix Range#{max,minmax} for range with integer beginning and non-integer endJeremy Evans2020-07-131-2/+11
| | | | | | | | | | | | | Previously, for inclusive ranges, the max would show up as the end of the range, even though the end was not an integer and would not be the maximum value. For exclusive ranges, max/minmax would previously raise a TypeError, even though it is possible to get the correct maximum. This change to max/minmax also uncovered a similar error in cover?, which calls max in certain cases, so adjust the code there so that cover? still works as expected. Fixes [Bug #17017]
* Fix non-numeric exclusive Range#minmax bugSam Bostock2020-07-041-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Deprecate taint/trust and related methods, and make the methods no-opsJeremy Evans2019-11-181-10/+0

* Make Range#=== operate like cover? instead of include? for string rangesJeremy Evans2019-08-141-0/+8
| | | | | | | | | | | | | | | | | | 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]
* Implement Range#minmaxJeremy Evans2019-08-141-0/+21
| | | | | | | | | 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]

* enumerator.c: Introduce Enumerator::ArithmeticSequencemrkn2018-08-061-1/+5
| | | | | | | | | | | | | | | | | | | 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.
