Is to run the test suite, find the last method which must A good technique to find potentially missing ruby2_keywords Previously, the ruby2_keywordsįlag was kept if the receiving method took *args, but this was a bug and an This will make it easier to transition to other ways ofĭelegation once a library can require Ruby 3+. Keyword arguments through *args must now be marked with ruby2_keywords, In other words, all methods wishing to delegate Methods taking a rest parameter (like *args) and wishing to delegate keywordĪrguments through foo(*args) must now be marked with ruby2_keywords The find pattern is no longer experimental. The following evaluation order is now used: Since Ruby 3.2, Regexp’s matching algorithm has been greatly improved by using a memoization technique.įoo1 :: BAR1, foo2 :: BAR2 = baz1, baz2 We have introduced two improvements that significantly mitigate ReDoS. If your code attempts to match a possibly inefficient Regexp against an untrusted input, an attacker may exploit it for efficient Denial of Service (so-called Regular expression DoS, or ReDoS). It is known that Regexp matching may take unexpectedly long.
