* rand_range: do not goto into a branch卜部昌平2020-06-291-1/+1
| | | | | I'm not necessarily against every goto in general, but jumping into a branch is definitely a bad idea. Better refactor.
* sed -i 's|ruby/impl|ruby/internal|'卜部昌平2020-05-111-1/+1
| | | | To fix build failures.
* sed -i s|ruby/3|ruby/impl|g卜部昌平2020-05-111-1/+1
| | | | This shall fix compile errors.
* Fixed constant initializerNobuyoshi Nakada2020-05-041-1/+1
| | | | | An expression using `static const` value seems not considered as `static const` by Visual C.
* Make int-pair-to-real conversion more portableNobuyoshi Nakada2020-05-041-5/+16
| | | | And utilize more bits even if DBL_MANT_DIG > 53.
* Disable deprecation error on mingwNobuyoshi Nakada2020-04-081-0/+2
|
* Merge pull request #2991 from shyouhei/ruby.h卜部昌平2020-04-081-2/+1
| | | Split ruby.h
* Ensure seed data to be clearedNobuyoshi Nakada2020-01-101-23/+14
| | | | To prevent from leaking the seed data.
* Fill siphash salt directly with random dataNobuyoshi Nakada2020-01-101-0/+6
| | | | | Expanding less random data with MT is not needed when it succeeded.
* Renamed `init_seed` as `init_hash_salt` tooNobuyoshi Nakada2020-01-091-2/+2
|
* Renamed `seed` as `hash_salt`Nobuyoshi Nakada2020-01-091-8/+8
| | | | | The role of this is a so-called "salt" but not "seed", rename to get rid of confusion with other "seed" of PRNG.
* Also clear MT to initialize the siphash seedNobuyoshi Nakada2020-01-091-0/+1

* decouple internal.h headers卜部昌平2019-12-261-18/+32
| | | | | | | | | | | | | | | | | | 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).
* add several __has_something macro卜部昌平2019-12-261-1/+1
| | | | | | | 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().
* rand(beginless_range) raise Errno::EDOM instead of TypeErrorKazuhiro NISHIYAMA2019-12-151-2/+4
| | | | | | | | | | | | | | | | | | | | | same as `rand(endless_range)` Before: ``` $ ruby -e 'rand(..1)' Traceback (most recent call last): 2: from -e:1:in `<main>' 1: from -e:1:in `rand' -e:1:in `-': nil can't be coerced into Integer (TypeError) ``` After: ``` $ ruby -e 'rand(..1)' Traceback (most recent call last): 1: from -e:1:in `<main>' -e:1:in `rand': Numerical argument out of domain (Errno::EDOM) ```
* Adjusted spaces [ci skip]Nobuyoshi Nakada2019-09-271-2/+2
|
* drop-in type check for rb_define_singleton_method卜部昌平2019-08-291-5/+5
| | | | | | 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.
* * expand tabs.git2019-06-041-1/+1

* random_mt_typeNobuyoshi Nakada2019-06-041-8/+8
| | | | | * random.c: renamed random_data_type as random_mt_type, and append "MT" to `wrap_struct_name`, respecting the implementation.

* blacklist UBSAN's unsigned integer overflowshyouhei2018-11-071-0/+3
| | | | | | | | | | | | 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.

* add new instruction attribute called leafshyouhei2018-09-111-1/+1
| | | | | | | | | | | 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.
