2020-06-20Add `mrb_get_arg1()` that retrieves single (and only) argument.Yukihiro "Matz" Matsumoto
`mrb_get_arg1()` raises `ArgumentError` if the method does not receive one argument. And replaces all `mrb_get_args(mrb, "o", &arg)` by the new function.

If occurs `NoMemoryError` exception in second `malloc()`, first `malloc()` pointer is not freed. commit fef1c152ce4e52b9e4a34dc23aca5b02907ac639 Author: dearblue <[email protected]> Date: Sat Jan 19 13:05:09 2019 +0900 Fix stack overflow when out of memory As a result of this change, no backtrace information is set for NoMemoryError (`mrb->nomem_err`). Detailes: When generating a backtrace, called `mrb_intern_lit()`, `mrb_str_new_cstr()` and `mrb_obj_iv_set()` function with `exc_debug_info()` function in `src/error.c`. If a `NoMemoryError` exception occurs at this time, the `exc_debug_info()` function will be called again, and in the same way `NoMemoryError` exception raised will result in an infinite loop to occurs stack overflow (and SIGSEGV). commit da7d7f881bbbad9988a3a2b7bad8f2b72ff06bc6 Author: dearblue <[email protected]> Date: Sun Jan 20 12:00:38 2019 +0900 Fix NULL pointer dereference `mrb->nomem_err` when not initialized Add internal functions (not `static`): * `mrb_raise_nomemory()` * `mrb_core_init_abort()`

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.

2019-03-27Fix another bug related to #4342Yukihiro "Matz" Matsumoto
For short symbols with alpha numeric characters, `mrb_sym2name_len()` returns the same buffer `mrb->symbuf`. Some occasion, we forget the fact that the second call could overwrite the result of first call of the function. We have prepared the static function `sym2name()` which specifies the buffer region for inline packed symbols and use the function in `mrb_sym_to_s`.

2019-02-06Implement symbol hash table to boost `find_symbol`.Yukihiro "Matz" Matsumoto
In 4174e02, we removed the symbol hash table from `mrb_state` but `find_symbol` was too slow with linear search. My performance estimation was wrong. So we implemented a new compact hash table for symbols.
2019-02-06Remove symbol hash table from `mrb_state` structure.Yukihiro "Matz" Matsumoto
Use linear search instead. Number of symbols is usually small (<1K), so we don't need performance boost from hash tables. In our benchmark measurement, hash tables consumes 790KB for `build/full-debug/mrbtest`.
