2020-07-24Improve prototype for `mrb_objspace_page_slot_size()`; ref #5032dearblue
If it qualify a return type that is not a pointer with `const`, the compiler ignores it.
2020-07-24Avoid using FPU with `mruby-os-memsize`; ref #5032dearblue
And, in the calculation of the instance variable size, the fraction was always rounded down because of division of integers, so fix it. At the same time, test items that are no longer passed due to this change are deleted.
2020-07-23Fix a bug with `ht_index` called with `size==0`; fix #5046Yukihiro "Matz" Matsumoto
It happens when a hash made empty calls `rehash`.
2020-07-22Use more `mrb_field_write_barrier` for instance variables.Yukihiro "Matz" Matsumoto
2020-07-22Use more local variables.Yukihiro "Matz" Matsumoto
To make debugging easy, and to improve the performance little bit.
2020-07-22Move `gray_list` update from `gc_mark_children`.Yukihiro "Matz" Matsumoto
The responsibility moved to caller to avoid confusion. Currently the function is called from only 2 places, so it is relatively easy to ensure not to update `gray_list` in the caller. But the assumption may change in the future.
2020-07-22Avoid using `mrb_ary_modify` from the internal function.Yukihiro "Matz" Matsumoto
`mrb_ary_modify` calls `mrb_write_barrier`, so can cause the same problem of the past `push`. It is provided for use-level API.
2020-07-22Use `mrb_field_write_barrier` instead of `mrb_write_barrier` for `push`.Yukihiro "Matz" Matsumoto
When the array is very big, the simpler `mrb_write_barrier` causes calling `gc_mark_children` for big arrays repeatedly. That would hinder performance very badly.
2020-07-22Skip unnecessary `mark_context` if `mrb->c == mrb->root_c`.Yukihiro "Matz" Matsumoto
2020-07-21Fix the VM stack handling bug in 'mrb_yield_with_class()`; fix #5042Yukihiro "Matz" Matsumoto
2020-07-19Use `c` specifier for `mrb_get_args`.Yukihiro "Matz" Matsumoto
2020-07-19Add new specifier `c` to `mrb_get_args`.Yukihiro "Matz" Matsumoto
`C` retrieves a `mrb_value` that refers a class/module. `c` retrieves a `struct RClass*` pointer to a class/module.
2020-07-17Use `proc->env` to check `block_given?` if possible; fix #5039Yukihiro "Matz" Matsumoto
This bug has been there since mruby 1.4.0 (2018-04).

2020-07-06Avoid infinite loop when converting objects to strings.Yukihiro "Matz" Matsumoto
2020-07-04fix object_id of true, false, and undef all 0Rory OConnell
2020-07-02Cancel 9cdf439Yukihiro "Matz" Matsumoto
Should not free the pointer in `realloc` since it can cause use-after-free problem.
2020-06-25Remove unnecessary stack adjustment in `OP_CALL`.Yukihiro "Matz" Matsumoto
2020-06-25Free the original pointer if `realloc` failed.Yukihiro "Matz" Matsumoto
The POSIX `realloc` keep the original pointer untouched, so it can easily leads to memory leakage. `mrb_realloc()` should handle those bookkeeping, while `mrb_realloc_simple()` keeps the original `realloc` behavior.
2020-06-25Remove unnecessary `break` from `numeric.c`.Yukihiro "Matz" Matsumoto
2020-06-25Change flag names in preparation of `REnv` refactoring.Yukihiro "Matz" Matsumoto
2020-06-25Use `mrb_get_argc()` to improve performance.Yukihiro "Matz" Matsumoto
2020-06-22Skip `mrb_get_args()` in `mrb_ary_{aget,aset}` unless necessary.Yukihiro "Matz" Matsumoto
Use simpler `mrb_get_argc()` and `mrb_get_arg1()` instead.
2020-06-20Support integer and float combination in `mrb_equal()`.Yukihiro "Matz" Matsumoto
2020-06-20Move definition of `BasicObject#!=` to `mrblib`.Yukihiro "Matz" Matsumoto
C implementation used `mrb_funcall()` that bypassed many optimization.
2020-06-20Add `mrb_get_arg1()` that retrieves single (and only) argument.Yukihiro "Matz" Matsumoto
`mrb_get_arg1()` raises `ArgumentError` if the method does not receive one argument. And replaces all `mrb_get_args(mrb, "o", &arg)` by the new function.

If occurs `NoMemoryError` exception in second `malloc()`, first `malloc()` pointer is not freed. commit fef1c152ce4e52b9e4a34dc23aca5b02907ac639 Author: dearblue <[email protected]> Date: Sat Jan 19 13:05:09 2019 +0900 Fix stack overflow when out of memory As a result of this change, no backtrace information is set for NoMemoryError (`mrb->nomem_err`). Detailes: When generating a backtrace, called `mrb_intern_lit()`, `mrb_str_new_cstr()` and `mrb_obj_iv_set()` function with `exc_debug_info()` function in `src/error.c`. If a `NoMemoryError` exception occurs at this time, the `exc_debug_info()` function will be called again, and in the same way `NoMemoryError` exception raised will result in an infinite loop to occurs stack overflow (and SIGSEGV). commit da7d7f881bbbad9988a3a2b7bad8f2b72ff06bc6 Author: dearblue <[email protected]> Date: Sun Jan 20 12:00:38 2019 +0900 Fix NULL pointer dereference `mrb->nomem_err` when not initialized Add internal functions (not `static`): * `mrb_raise_nomemory()` * `mrb_core_init_abort()`

2020-05-24Do not destruct rest arguments for __send__Yusuke Endoh
Formerly, `__send__(*args)` modified `args` with `Array#shift`. This bug affects optcarrot. This changeset avoids the array destruction by using `args = args[1, len-1]`.

2020-05-09Remove byteorder constants; ref 87576b8dearblue
The `FLAG_BYTEORDER_NATIVE` and `FLAG_BYTEORDER_NONATIVE` are no longer needed.
2020-05-07Update `cmpnum` document.Yukihiro "Matz" Matsumoto
`cmpnum` function may return `nil` on error.
2020-05-07Remove endian information/flags from compiled binary format.Yukihiro "Matz" Matsumoto
Since `mruby 2.0`, compiled bytecode no longer depends on the endian of the machine.
2020-05-07Add a new instruction `OP_LOADI16`.Yukihiro "Matz" Matsumoto
Which loads 16bit integer to the register. The instruction number should be reorder on massive instruction refactoring. The instruction is added for `mruby/c` which had performance issue with `OP_EXT`. With this instruction, `mruby/c` VM can just raise errors on `OP_EXT` extension instructions.
2020-05-07Remove `mrb_run` from `MRB_API`; #4488Yukihiro "Matz" Matsumoto
`mrb_run` requires to push callinfo stack before calling, which is very hard from outside of `vm.c`. So there should be virtually no correct usage of the function, hence the cause of #4488. We removed it. You can use `mrb_top_run(mrb, proc, self, 0)` instead of `mrb_run(mrb, proc self)`.
2020-04-29Makes `mrb_any_to_s()` accept an object whose class is `NULL`dearblue
When using `mrb_any_to_s()` for debugging purposes, giving an object whose class is `NULL` no longer causes a SIGSEGV and no crash. This is achieved by making `mrb_class_name()` and `mrb_str_cat_cstr()` null safe.
