2020-10-12Use `NULL` instead of `0`; close #2467Yukihiro "Matz" Matsumoto
The PR was from @cubicdaiya.
2020-10-12Restore old function names for compatibility; ref #5070Yukihiro "Matz" Matsumoto
- `mrb_check_intern()` to return `mrb_value` - `mrb_intern_check()` to return `mrb_sym` [NEW] Other new functions: - `mrb_intern_check_cstr()` - `mrb_intern_check_str()`
2020-10-12Abandon packing all lower case symbols with 6 characters.Yukihiro "Matz" Matsumoto
To make packed inline symbols within 31 bits, because the new method hash tables allows only 31 bits of symbols. They use top 1 bit to maek unused slots.
2020-10-12Change the return type of `mrb_check_intern()` and friends.Yukihiro "Matz" Matsumoto
They used to return `mrb_value` but now return `mrb_sym` for consistency with other `intern` functions. If symbols are not defined, `check` functions return `0`, instead of `nil` in the past. It causes API incompatibility but I believe few people use those functions out of the core, and those changes are very easy to handle, hopefully.
2020-10-12Enable NUL (`\0`) again.Yukihiro "Matz" Matsumoto
2020-10-12Generate C struct from `irep` instead of binary dump.Yukihiro "Matz" Matsumoto
2020-10-12Stringify non C identifier symbols to stop macro errors by old gcc.Yukihiro "Matz" Matsumoto
2020-10-12Rename `MRB_OPSYM()` to `MRB_QSYM()`.Yukihiro "Matz" Matsumoto
Where `QSYM` means quoted symbols, which cannot be represented C symbols, so specify aliases instead. - operators: name of the operation, e.g. add for `+` - predicates: add `_p` suffix instead of `?` - bang methods: add `_b` suffix instead of `!` - instance variables: add `a_` prefix instead of `@` - global variables: add `d_` prefix instead of `@` - class variables: unsupported; don't use them
2020-10-12Create `MRB_OPSYM()` macro to refer symbols corresponding operators.Yukihiro "Matz" Matsumoto
For example, `MRB_OPSYM(add)` refers a symbol for `+`.
2020-10-12Fix `presym_find` for strings without `NUL` terminators.Yukihiro "Matz" Matsumoto
2020-10-12Update `presym_find` to use more efficient binary search.Yukihiro "Matz" Matsumoto
2020-10-12Add `MRB_SYM()` for inline symbols.Yukihiro "Matz" Matsumoto
2020-10-12Support `presym` in `symbol.c`.Yukihiro "Matz" Matsumoto
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`.

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`.
