2015-05-07Defining static version of frexpl also fro MIPS platforms.Paolo Bosetti
On MIPS/linaro, libm.so lacks frexpl() as CygWin does.

prevent accidental macro redefinition of strndup()
2015-04-29always define SIZE_ERROR_MUL() macrocremno
Previously there wasn't a way to trigger the useful definition, but it is needed and that in every case to check for integer overflow due to multiplication and faulty/modified binary files. Also change existing code to a calloc()-like parameter order.
2015-04-29remove SIZE_ERROR() macrocremno
It's only used once and in that case it isn't necessary anyway, since size_t must be at least 32 bits wide and the max. length of a filename is UINT16_MAX.

parser_state->locals might be a null pointer. Fixes (and other similiar invalid code): def a; Proc.new do def x==x end end

2015-04-28fix possible unsigned integer underflowcremno
buf_size has to be greater than header_size, otherwise subtracting header_size from buf_size will cause an integer underflow. Being equal to header_size is fine, however useless, so quit early.

Convert mrb_read_irep_file() to use goto like read_section_lv() and read_section_debug() already do.

No need to write the same assertion in each case (except the default one). Instead we can assert after the switch statement.

2015-02-25Fix a crash bug on raising after reallocKouhei Sutou
The following program reproduces this problem: #include <mruby.h> static mrb_value recursive(mrb_state *mrb, mrb_value self) { mrb_int n; mrb_get_args(mrb, "i", &n); if (n == 0) { mrb_raise(mrb, E_RUNTIME_ERROR, "XXX"); } else { mrb_funcall(mrb, self, "recursive", 1, mrb_fixnum_value(n - 1)); } return self; } int main(void) { mrb_state *mrb; mrb = mrb_open(); mrb_define_method(mrb, mrb->kernel_module, "recursive", recursive, MRB_ARGS_REQ(1)); mrb_funcall(mrb, mrb_top_self(mrb), "recursive", 1, mrb_fixnum_value(30)); mrb_close(mrb); } Recursive method call isn't required. It's just for expanding call info stack. If mrb_realloc() is called in cipush(), cibase address is changed. So, we shouldn't compare ci before mrb_realloc() and cibase after mrb_realloc(). It accesses unknown address and causes crash.

2015-02-23fix pointer dereference after reallocGo Saito
In src/vm.c: mrb_funcall_with_block stack_extend may realloc mrb->c->stbase, if argv points on mruby's stack, then it points invalid address after stack_extend. e.g. src/class.c: mrb_instance_new This code: ```ruby class A def initialize(a0,a1,a2,a3,a4) a0.is_a? Array end end def f(a0,a1,a2,a3,a4) A.new(a0,a1,a2,a3,a4) f(a0,a1,a2,a3,a4) end f(0,1,2,3,4) ``` is expected to get exception ``` stack level too deep. (limit=(0x40000 - 128)) (SystemStackError) ``` but get segfault. Signed-off-by: Go Saito <[email protected]>

re-implement mrb_float_to_str()
2015-02-13re-implement mrb_float_to_str()cremno
The new implementation is backwards incompatible, but I couldn't find any usage outside mruby and I also couldn't think of a different and good name. All ISO C99 printf conversion specifiers for floating point numbers and an optional precision are supported. It is largely based on code from the MIT licensed musl libc (http://www.musl-libc.org/) and its floating point printing is exact (unlike the current code behind Float#to_s).

2015-02-02allow endian specification of mrb files by `mrbc -e/-E`Yukihiro "Matz" Matsumoto
`mruby -b` now accepts both big/little endian mrb (compiled binary) files. `mrbc` generates mrb files in big endian for .mrb files and in native endian for C files (with -B option specified) by default. If you are cross compiling, you need to specify target endian by -e/-E options if it is different from host endian.
