Yukihiro "Matz" Matsumoto 86d102350b Restrict total recursion number of ecall(); fix #3789 2018-11-20 09:14:34 +09:00
Yukihiro "Matz" Matsumoto ff08856fe3 Remove implicit conversion using to_str method; fix #3854 
We have added internal convenience method `__to_str` which
does string type check.

The issue #3854 was fixed but fundamental flaw of lack of stack
depth check along with fibers still remains. Use `MRB_GC_FIXED_ARENA`
for workaround.

Yukihiro "Matz" Matsumoto afca99a40b Remove implicit conversion using to_int method. 
The ISO standard does not include implicit type conversion using
`to_int`. This implicit conversion often causes vulnerability.
There will be no more attacks like #4120.

In addition, we have added internal convenience method `__to_int` which
does type check and conversion (from floats).

Yukihiro "Matz" Matsumoto bbb0882343 Modifying frozen objects will raise FrozenError. 
`FrozenError` is a subclass of `RuntimeError` which used to be
raised.  [Ruby2.5]

Yukihiro "Matz" Matsumoto b00d45b095 mrb_method_search_vm() should gives the defined class. 
Otherwise `super` may call a wrong method.
 2017-12-06 17:28:20 +09:00
Yukihiro "Matz" Matsumoto 8f2c62407c Add MRB_METHOD_TABLE_INLINE option. 
Now the method tables (in classes/modules and caches) keeps C function
pointers without wrapping in `struct RProc` objects. For the sake of
portability, `mrb_method_t` is represented by the struct and union, but
if the most significant bit of the pointer is not used by the platform,
`mrb_method_t` should be packed in `uintptr_t` to reduce memory usage.

`MRB_METHOD_TABLE_INLINE` is turned on by default for linux.

Yukihiro "Matz" Matsumoto 0c52112dd4 Keep Range class in mrb_state structure for performance. 2017-08-26 02:01:50 +09:00
Yukihiro "Matz" Matsumoto 4c9a604877 Added method cache. 
To enable method cache, define `MRB_METHOD_CACHE` or
`MRB_METHOD_CACHE_SIZE`. The cache size must be power of 2.
The default cache size is 128.

The measurement:
I measured simple benchmarks found in benchmark/ directory. With
method cache enabled, we gained 6-8% performance improvement, with
97-99% cache hit rate.

Yukihiro "Matz" Matsumoto 3f90af6b42 (Try to) fix mixture of int and size_t in UTF-8 conversion. 
This only effects VC.

Yukihiro "Matz" Matsumoto 329938ef15 Simplify mrb_gc_arena_restore() to reduce overhead. 
It will no longer shrink arena region. Instead `vm.c` uses
a static function `mrb_gc_arena_shrink()` to shrink.

Yukihiro "Matz" Matsumoto ce6c05600a Add fallback definitions of DBL_EPSILPN and LDBL_EPSILON; fix #3733

Yukihiro "Matz" Matsumoto bb1bfaa2fb Add helper functions to use gdb reverse-next. 
On my machine, gdb reverse-next does not work with memcpy and memset.
Add naive implementation of those functions to override.

Yukihiro "Matz" Matsumoto 788cea2b43 Revert "Simplify rescue stack management; ref #3683" 
This reverts commit eb5a606fe2 and
079f310fbc.
The rescue stack works differently from ensure stack, so the change
caused #3686 and #3688. It might take long to solve the problems,
so that I would revert the changes for now. Fix #3688

Yukihiro "Matz" Matsumoto 9644ad51b4 Simplify backtrace mechanism; fix #3633 #3634 #3644 
Instead of preserving a backtrace in `mrb_state`, `mrb_exc_set`
keeps packed backtrace in an exception object. `#backtrace` unpacks
it to an array of strings.

Yukihiro "Matz" Matsumoto 6a0b68f8b8 Use trampoline technique for instance_exec; ref #3359 
A new function `mrb_yield_cont()` is provided. You have to call it
at the end of a C defined method, e.g. `return mrb_yield_cont()`.

Yukihiro "Matz" Matsumoto 30aa521854 Do not use mrb_funcall() if Hash#default is not overridden; ref #3421 
This change reduces the recursion level, but does not solve the stack
overflow issue entirely.
