2017-12-23Do not include object string representation in `NoMethodError` message.Yukihiro "Matz" Matsumoto
This information is not mandatory but causes a lot of problems in the past due to infinite recursion by redefining `to_str`, `inspect` etc.
2017-11-20Add `MRB_METHOD_TABLE_INLINE` option.Yukihiro "Matz" Matsumoto
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.

2017-11-04Reimplement `block_given?`; ref #3841Yukihiro "Matz" Matsumoto
Make `block_given?` to search for the top of the scope first. The top of the scope means either: * the top method body * the enclosing class body * the top-level The special case is the method defined by `define_method` with a block as in #3841. In cases like this, the method body (given by a block) is not considered as the top of the scope. You need to use `&block` in the block parameter if you want to know if a block is given to the method. This commit also changes the behavior of `MRB_PROC_SCOPE` flag. Now it is only set if the `proc` is either a class body or a method body defined in Ruby. It is no longer set for a block that given to `define_method`.
2017-11-04The `bidx` saved in `env` may be useless; fix #3841Yukihiro "Matz" Matsumoto
When `block_given?` is called from a block given to `define_method` as a method body, the `bidx` may not be within `env` saved closure. In this case, it causes heap buffer overflow.

2017-10-28Heavily refactored how lexical scope links are implemented; fix #3821Yukihiro "Matz" Matsumoto
Instead of `irep` links, we added a `upper` link to `struct RProc`. To make a space for the `upper` link, we moved `target_class` reference. If a `Proc` does not have `env`, `target_class` is saved in an `union` shared with `env` (if a `Proc` has env, you can tell it by `MRB_PROC_ENV_P()). Otherwise `target_class` is referenced from `env->c`. We removed links in `env` as well. This change removes 2 members from `mrb_irep` struct, thus saving 2 words per method/proc/block. This also fixes potential memory leaks due to the circular references caused by a link from `mrb_irep`.

'int', possible loss of data
2017-09-04Restructure `irep->outer` chain; fix #3804Yukihiro "Matz" Matsumoto
Instead of `irep -> proc` chain, we use `irep -> irep` chain to avoid GC bugs like #3804. We added `target_class` reference to `mrb_irep` struct. That means one more word consumption per `irep`.
2017-08-02Now `local_variables` works when for closures; fix #3710Yukihiro "Matz" Matsumoto

2017-06-02Fixed a bug that make a loop in singleton_class clone; fix #3687Yukihiro "Matz" Matsumoto
2017-05-23Simplify backtrace mechanism; fix #3633 #3634 #3644Yukihiro "Matz" Matsumoto
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.
2017-04-22Keep reference to mrb_context from env; fix #3619Yukihiro "Matz" Matsumoto

2017-04-03Restrict recursion levels in method_missing(); fix #3556Yukihiro "Matz" Matsumoto
Note this is a temporary fix. Error message generation (including `inspect`) should be deferred until its use.
2017-03-18Avoid mrb_check_string_type() in raising exception; fix #3506Yukihiro "Matz" Matsumoto
The change may reduce flexibility, but I believe no one wants that level of flexibility here.

More compatibility to CRuby. Updated tests that assume old mruby behavior.
2017-02-14Do not use mrb_funcall() if Hash#default is not overridden; ref #3421Yukihiro "Matz" Matsumoto
This change reduces the recursion level, but does not solve the stack overflow issue entirely.
2017-02-06Kernel#local_variables: Make result array uniqueksss
2017-02-04`argv` may be modified when `mrb_funcall()` is called; fix #3419Yukihiro "Matz" Matsumoto
Calling `mrb_funcall()` and `mrb_yield()` (and their related functions) are discouraged unless absolutely necessary, because it can cause this kind of issues very easily.

Inline structures have no instance variables, no finalizer, and offer as much space as possible in RBASIC object. This means 24 bytes on 64-bit platforms and 12 bytes on 32-bit platforms. mruby-inline-struct gem is only provided for testing.
