2017-10-31Fixed constant (and class variable) reference bug; fix #3839Yukihiro "Matz" Matsumoto
Unlike method definition, constant reference should start from `MRB_PROC_TARGET_CLASS(ci->proc)`, not `ci->target_class`. In addition, `MRB_PROC_TARGET_CLASS(ci->proc)` is always set.
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`.
2017-10-17Remove top-level constant lookup; CRuby2.5Yukihiro "Matz" Matsumoto
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`.
2017-08-26Remove unused `mrb_obj_iv_ifnone()` from API.Yukihiro "Matz" Matsumoto
2017-08-26Add checks if `iv_tbl` is NULL.Yukihiro "Matz" Matsumoto
2017-08-26Use `khash` for instance variables tables instead of segment list.Yukihiro "Matz" Matsumoto
For performance reason. Segmented list consumes slightly less memory but takes a lot of time especially when there are many slots in the segment lists (e.g. class constants).
2017-08-19Type check before traversing `irep->outer`; fix #3782Yukihiro "Matz" Matsumoto
2017-08-18`capacify' for `mrb_str_new_capa` should not be `0`.Yukihiro "Matz" Matsumoto
2017-08-18Separate `mrb_str_buf_new` and `mrb_str_new_capa`.Yukihiro "Matz" Matsumoto
`mrb_str_buf_new` is an old function that ensures capacity size of `MRB_STR_BUF_MIN_SIZE` minimum. Usually one need to use `mrb_str_new_capa` instead.
2017-08-01Better class name management.Yukihiro "Matz" Matsumoto
The change removes several internal instance variables used by class name management. The variables `__classid__` and `__classpath__` are no longer available. `__outer__` is used only for unnamed outer classes/modules (and will be removed after they are named). [Important note] Along with this change we removed several public functions. - mrb_class_outer_module() - mrb_class_sym() We believe no one have used those functions, but if you do, please ask us for the workaround.

From `mrb_mod_const_set` to `mrb_const_set`.

2015-07-16use mrb_str_cat_str() instead of mrb_str_append()cremno
If the argument is always a string, then mrb_str_cat_str() can be directly called instead of indirectly by mrb_str_append(). mrb_any_to_s(), mrb_obj_as_string(), mrb_inspect() always return a string.
2015-06-24Remove unnecessary backticks.Franck Verrot
Dr Markus Kuhn published in 1999 an article [1] explaining in details why we shouldn't use the ASCII grave accent (0x60) as a left quotation. Backticks have been used most notably to produce nice-looking LaTeX documents but it doesn't seem to be an issue on modern platforms and for the oldest ones, there are workarounds as mentioned by Dr Kuhn.
