2020-06-29rand_range: do not goto into a branch卜部昌平
I'm not necessarily against every goto in general, but jumping into a branch is definitely a bad idea. Better refactor. Notes: Merged: https://github.com/ruby/ruby/pull/3247
2020-05-11sed -i 's|ruby/impl|ruby/internal|'卜部昌平
To fix build failures. Notes: Merged: https://github.com/ruby/ruby/pull/3079
2020-05-11sed -i s|ruby/3|ruby/impl|g卜部昌平
This shall fix compile errors. Notes: Merged: https://github.com/ruby/ruby/pull/3079
2020-05-04Fixed constant initializerNobuyoshi Nakada
An expression using `static const` value seems not considered as `static const` by Visual C.

And utilize more bits even if DBL_MANT_DIG > 53.

2020-01-10Ensure seed data to be clearedNobuyoshi Nakada
To prevent from leaking the seed data. Notes: Merged: https://github.com/ruby/ruby/pull/2826
2020-01-10Fill siphash salt directly with random dataNobuyoshi Nakada
Expanding less random data with MT is not needed when it succeeded. Notes: Merged: https://github.com/ruby/ruby/pull/2826
2020-01-09Renamed `init_seed` as `init_hash_salt` tooNobuyoshi Nakada
2020-01-09Renamed `seed` as `hash_salt`Nobuyoshi Nakada
The role of this is a so-called "salt" but not "seed", rename to get rid of confusion with other "seed" of PRNG. Notes: Merged: https://github.com/ruby/ruby/pull/2825
2020-01-09Also clear MT to initialize the siphash seedNobuyoshi Nakada
2019-12-26decouple internal.h headers卜部昌平
Saves comitters' daily life by avoid #include-ing everything from internal.h to make each file do so instead. This would significantly speed up incremental builds. We take the following inclusion order in this changeset: 1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very first thing among everything). 2. RUBY_EXTCONF_H if any. 3. Standard C headers, sorted alphabetically. 4. Other system headers, maybe guarded by #ifdef 5. Everything else, sorted alphabetically. Exceptions are those win32-related headers, which tend not be self- containing (headers have inclusion order dependencies). Notes: Merged: https://github.com/ruby/ruby/pull/2711
2019-12-26add several __has_something macro卜部昌平
With these macros implemented we can write codes just like we can assume the compiler being clang. MSC_VERSION_SINCE is defined to implement those macros, but turned out to be handy for other places. The -fdeclspec compiler flag is necessary for clang to properly handle __has_declspec(). Notes: Merged: https://github.com/ruby/ruby/pull/2711

2019-08-29drop-in type check for rb_define_singleton_method卜部昌平
We can check the function pointer passed to rb_define_singleton_method like how we do so in rb_define_method. Doing so revealed many arity mismatches.

Integer overflow for unsigned types are fully defined in C. They are not always problematic (but not always OK). These functions in this changeset intentionally utilizes that behaviour.

2018-09-11add new instruction attribute called leafshyouhei
An instruction is leaf if it has no rb_funcall inside. In order to check this property, we introduce stack canary which is a random number collected at runtime. Stack top is always filled with this number and checked for stack smashing operations, when VM_CHECK_MODE.

* 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. Otherwise falls back to OpenSSL. Current preference is: 1. CSPRNG routine that the OS has; one of - getrandom(2), - arc4random(3), or - CryptGenRandom() 2. /dev/urandom device 3. OpenSSL's RAND_bytes(3) If none of above random number generators are available, you cannot use this module. An exception is raised that case. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@57384 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
