2017-11-11Fixed wrong stack extend size; fix #3847Yukihiro "Matz" Matsumoto
2017-11-10Need to clear stack region for local variables in eval; fix #3844Yukihiro "Matz" Matsumoto
2017-11-09Use proper target_class to define class/module; fix #3843Yukihiro "Matz" Matsumoto
The outer class of the class/module definition should be taken from `MRB_TARGET_CLASS(mrb->c->ci->proc)` not `mrb->c->ci->target_class` which is the target of constant lookups.

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`.

2017-11-03Always check division-by-zero to avoid undefined behavior; fix #3816Yukihiro "Matz" Matsumoto
Also removed the code to normalize NaN value for `MRB_NAN_BOXING`. Tha code was added to fix #1712 but no longer required after 249f05e7d.
2017-10-31Call stack may not reference the destination `proc`; fix #3838Yukihiro "Matz" Matsumoto
The destination `proc` may be an orphan.
2017-10-28Removed a debug printf; fix #3834Yukihiro "Matz" Matsumoto
2017-10-28Remove one of the lines that did the same thing; fix #3836Yukihiro "Matz" Matsumoto
The change is suggested by `ukrainskiysergey` in #3836. I deleted the other line for clarity. I also updated comment lines.
2017-10-28Should clear ensure stack at `OP_RETURN break`; #3715Yukihiro "Matz" Matsumoto
This is a resurrection of d0a7e01, which is accidentally removed by 93f5f22; Fix #3715
2017-10-28Should check if `callinfo` stack is popped before updating the stack.Yukihiro "Matz" Matsumoto
This is a resurrection of 75c374c, which is accidentally removed by 93f5f22; Fix #3507 #3512 #3518 #3521
2017-10-28Fixed UPVAR gotchas; fix #3835Yukihiro "Matz" Matsumoto
Both `uvenv` function and `env` generation in `create_proc_from_string` function have bugs to handling enclosed environment objects.
2017-10-28Remove a debug variableYukihiro "Matz" Matsumoto
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`.

2017-09-23The first instruction was skipped mistakenly in ensure clause; fix #3811Yukihiro "Matz" Matsumoto

2017-09-12Remove temporary limitation of `OP_EPOP`.Yukihiro "Matz" Matsumoto
After f68f5f6, the operand of `OP_EPOP` should have been `1`. Now we have removed the limitation.
2017-09-11The callinfo stack may be reallocated in `cipush`; fix rest of #3809Yukihiro "Matz" Matsumoto
fix #3809
2017-09-11The ensure stack may be empty at `OP_EPOP`; fix 1st part of #3809Yukihiro "Matz" Matsumoto
2017-09-05Avoid crossing C function boundary from `OP_EPOP`; ref #3789Yukihiro "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`.
2017-08-30Fixed a critical typo; ref #3798Yukihiro "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.
2017-08-18Reset ci in OP_SUPER after potential reallocChristopher Aue
2017-08-12Reintroduced not storing converted proc directly in the stackChristopher Aue
2017-08-12Removed unneeded ci->nregs checks in OP_SEND and OP_SUPERChristopher Aue
Because of #3504 `ci->nregs = bidx+1` was introduced in b64f08784cc50861dec80c26fce715982c02c9e9. This led to the follow up error #3551 whose fix introduced the `if (bidx >= ci->nregs)` check in 071164b7999d0932fd60fb3c580a6c374ab1cf4f and the `stack_extend(mrb, ci->nregs)` in 93d802987e722444d0520a8d3f28002841c4f825. Then, the code causing #3504 reappeared again in #3590. The fix for it moved the code dealing with the block in OP_SUPER from below the `cipush` to above the `cipush` in d9fb8b69b0621e8cd2c7c43fd8511a83718d7e45. The `if (bidx >= ci->nregs) { ... }` from then on works with the original callinfo and not the pushed one. `ci->nregs` needed to be modified for the pushed one because it is initialized to 0. But for the original ci it is propertly set and a check is not needed.
