2020-11-27per-ractor Random::DEFAULTKoichi Sasada
Random generators are not Ractor-safe, so we need to prepare per-ractor default random genearators. This patch set `Random::DEFAULT = Randm` (not a Random instance, but the Random class) and singleton methods like `Random.rand()` use a per-ractor random generator.

2020-01-29Revert "srand() should not run in tests."Koichi Sasada
This reverts commit 4d132fa130e16eeb4af4177cfaccc00e05e2f864. There are discussions about using srand() in tests. I'll write a ticket about it and continue to discuss.
2020-01-29Revert "remove debug code."Koichi Sasada
This reverts commit 65768c80beb64a14c3e918f8ed5e41e9349025d0.

2020-01-28srand() should not run in tests.Koichi Sasada
test_rand.rb calls srand() several times, however it change global rand-sequence (and --seeds doesn't have meaning). This patch makes such tests run in other processes. Notes: Merged: https://github.com/ruby/ruby/pull/2865

2017-12-12Add FrozenError as a subclass of RuntimeErrorshyouhei
FrozenError will be used instead of RuntimeError for exceptions raised when there is an attempt to modify a frozen object. The reason for this change is to differentiate exceptions related to frozen objects from generic exceptions such as those generated by Kernel#raise without an exception class.

* random.c (InitVM_Random): rename Random.raw_seed to Random.urandom. A quick search seems there are no practical use of this method than securerandom.rb so I think it's OK to rename but if there are users of it, this hunk is subject to revert. * test/ruby/test_rand.rb (TestRand#test_urandom): test for it. * lib/securerandom.rb (SecureRandom.gen_random): Prefer OS- provided CSPRNG if available.

OpenSSL's RAND_bytes(3) If none of above random number generators are available, you cannot use this module.
