2018-11-19Add Hash type check for `OP_KARG` and `OP_KEY_P`; ref #4166Yukihiro "Matz" Matsumoto
2018-11-19Adjust codedump output format; ref #4166Yukihiro "Matz" Matsumoto
2018-11-19Use type checking `mrb_to_str` instead of converting `mrb_str_to_str`.Yukihiro "Matz" Matsumoto
2018-11-19Removed `to_hash` conversion method.Yukihiro "Matz" Matsumoto
2018-11-19Removed `to_ary` conversion method.Yukihiro "Matz" Matsumoto
2018-11-19Remove implicit conversion using `to_str` method; fix #3854Yukihiro "Matz" Matsumoto
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.
2018-11-19Remove implicit conversion using `to_int` method.Yukihiro "Matz" Matsumoto
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).
2018-11-19The current context may be changed in `mrb_vm_exec`; ref #3668 #4104Yukihiro "Matz" Matsumoto
2018-11-19Protect Fiber from GC in `ecall()`; fix #4104Yukihiro "Matz" Matsumoto
2018-11-19Improve Hash table using variable sized segments.Yukihiro "Matz" Matsumoto
2018-11-16The key or value object could be reclaimed by GC; fix #4164Yukihiro "Matz" Matsumoto
The GC may occur between `sg_shift` and `mrb_assoc_new`, in which case `key` and `value` could be freed even tough they are still alive. The issue is found and fixed by https://hackerone.com/hexodus
2018-11-15The saved `pc` from `ERR_PC_SET` was wrong; fix #4138Yukihiro "Matz" Matsumoto
The saving `pc` position should be beginning of the instruction. But after `mruby 2.0` byte code modification, the `pc` variable points the beginning of the next instruction. We save the previous position in a local variable `pc0`.
2018-11-15Rename local variables in `mrb_debug_info_append_file`Yukihiro "Matz" Matsumoto
2018-11-15Simplify argument parsing; ref #4161Yukihiro "Matz" Matsumoto

2018-11-15Remove `filename`&`lines` from `mrb_irep` struct.Yukihiro "Matz" Matsumoto
This patch slightly reduce memory consumption (2% for my test).

2018-11-02Remove reserved symbols for now.Yukihiro "Matz" Matsumoto
It should be done by planned embedded symbols.

2018-11-01The `env` object referenced from fibers may be freed; fix #4154Yukihiro "Matz" Matsumoto
By dffa203 that reclaim `env` objects from heaps, there's more chance for `env` objects referenced from fibers may be freed from heap pages.

2018-10-29We need no write barrier here; ref #4143Yukihiro "Matz" Matsumoto
2018-10-29Marking from terminated fibers are not needed; ref #4143Yukihiro "Matz" Matsumoto
The old condition marks the top-level callinfo even after the fiber is terminated.
2018-10-29Need to mark shared env objects as `MRB_TT_FREE`; fix #4143Yukihiro "Matz" Matsumoto
The following code mistakenly exits from the function without marking the env object as `MRB_TT_FREE`. ``` ruby if (MRB_ENV_STACK_SHARED_P(e)) { /* cannot be freed */ return; // <- should be `break` } ```
2018-10-29Add argument check to `Array#clear`; fix #4144Yukihiro "Matz" Matsumoto

2018-10-12Should not compare `undef` (deleted) key in hashes; fix #4136Yukihiro "Matz" Matsumoto
2018-10-12Add `NULL` check in `sg_compact()`; fix #4139Yukihiro "Matz" Matsumoto

2018-09-26Add index to larger segment lists for performanceYukihiro "Matz" Matsumoto
2018-09-26Use `mrb_undef_value` for delete mark instead of shifting Hash entry table.Yukihiro "Matz" Matsumoto
That means entry table should be compacted periodically by `sg_compact()`.
2018-09-26Use segmented list to implement `Hash` [Experimental]Yukihiro "Matz" Matsumoto
I know it's not hash at all, but reduce memory consumption.
