2019-04-01Avoid keeping pointers from `mrb_sym2name_len()`; fix #4342Yukihiro "Matz" Matsumoto
The addresses for packed inline symbols reference `mrb->symbuf` that could be overridden by the later call of `mrb_sym2name_len`. Since file names in call stack information are kept as symbols, keeping the address in the C structures could cause problems like #4342. This changes small incompatible changes in function prototypes: * `mrb_parser_get_filename`: return value changed to `mrb_sym`. * `mrb_debug_get_filename`: add `mrb_state*` as a first argument. * `mrb_debug_get_line`: ditto. I believe above functions are almost internal, and no third-party mrbgem use them.

2019-02-07Add `OP_ENTER` to blocks without parameters; fix #4175Yukihiro "Matz" Matsumoto
So that `lambda{}.call(1)` raises `ArgumentError` as CRuby does. Also, fixed junk assignment for `lambda{|;a|p a}.call{}`.
2018-12-31Should not check non-node value to `void_expr_error`; fix #4203Yukihiro "Matz" Matsumoto
This is also a reason for #4192 as well.
2018-12-21Add `NULL` pointer check before `void_expr_error()`; fix #4192Yukihiro "Matz" Matsumoto
2018-11-25Allow destructuring in formal arguments.Yukihiro "Matz" Matsumoto
e.g. ``` def m(a,(b,c),d); p [a,b,c,d]; end m(1,[2,3],4) # => [1,2,3,4] ``` mruby limitation: Destructured arguments (`b` and `c` in above example) cannot be accessed from the default expression of optional arguments and keyword arguments, since actual assignment is done after the evaluation of those default expressions. Thus: ``` def f(a,(b,c),d=b) p [a,b,c,d] end f(1,[2,3]) ``` raises `NoMethodError` for `b` in mruby.

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`.
