Notes: Merged: https://github.com/ruby/ruby/pull/3966
2020-12-14Deprecate Random::DEFAULTBenoit Daloze
* Closes [Feature #17351].
2020-12-14Remove references to Random::DEFAULT in the documentationBenoit Daloze
* Random::DEFAULT is no longer a Random instance, and referencing it is more confusing than helpful. Related to [Feature #17351]
2020-12-01ractor local storage C-APIKoichi Sasada
To manage ractor-local data for C extension, the following APIs are defined. * rb_ractor_local_storage_value_newkey * rb_ractor_local_storage_value * rb_ractor_local_storage_value_set * rb_ractor_local_storage_ptr_newkey * rb_ractor_local_storage_ptr * rb_ractor_local_storage_ptr_set At first, you need to create a key of storage by rb_ractor_local_(value|ptr)_newkey(). For ptr storage, it accepts the type of storage, how to mark and how to free with ractor's lifetime. rb_ractor_local_storage_value/set are used to access a VALUE and rb_ractor_local_storage_ptr/set are used to access a pointer. random.c uses this API.

2020-11-27Use opaque struct pointer than voidNobuyoshi Nakada
2020-11-27mark default_randKoichi Sasada
default_rand can points a Bignum seed, so it should be marked.
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.

2020-09-07Added WITH_REAL macrosNobuyoshi Nakada
Added `WITH_REAL` versions to `RB_RANDOM_INTERFACE` macros. Also these macros including "without real" versions no longer contain the terminator (semicolon and comma). Notes: Merged: https://github.com/ruby/ruby/pull/3024

2020-09-07separate rb_random_tNobuyoshi Nakada
* random.c: separate abstract rb_random_t and rb_random_mt_t for Mersenne Twister implementation. * include/ruby/random.h: the interface for extensions of Random class. * DLL imported symbol reference is not constant on Windows. * check if properly initialized.

* random.c (InitVM_Random): introduce abstract super class Random::Base. Notes: Merged: https://github.com/ruby/ruby/pull/3024
2020-08-15RARRAY_AREF: convert into an inline function卜部昌平
RARRAY_AREF has been a macro for reasons. We might not be able to change that for public APIs, but why not relax the situation internally to make it an inline function. Notes: Merged: https://github.com/ruby/ruby/pull/3419
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

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.
2020-05-04Make int-pair-to-real conversion more portableNobuyoshi Nakada
And utilize more bits even if DBL_MANT_DIG > 53.
2020-04-08Disable deprecation error on mingwNobuyoshi Nakada
2020-04-08Merge pull request #2991 from shyouhei/ruby.h卜部昌平
Split ruby.h Notes: Merged-By: shyouhei <[email protected]>
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

2019-09-27Adjusted spaces [ci skip]Nobuyoshi Nakada
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.
2019-06-04* expand tabs.git
2019-06-04random_mt_typeNobuyoshi Nakada
* random.c: renamed random_data_type as random_mt_type, and append "MT" to `wrap_struct_name`, respecting the implementation.

2018-11-07blacklist UBSAN's unsigned integer overflowshyouhei
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. Blacklist from UBSAN checks for better output.

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.
