2019-09-26Use type predicate macros instead of `mrb_type` if possibleKOBAYASHI Shuji
For efficiency with `MRB_WORD_BOXING` (implement type predicate macros for all `enum mrb_vtype`).
2019-08-19Move `mrb_str_pool` to `src/string.c` to use `str_init` familyKOBAYASHI Shuji

2019-08-12`mrb_str_pool` can embed one more byte; ref #4626KOBAYASHI Shuji
2019-08-11Reorder finalization to avoid potential crash; ref #4618Yukihiro "Matz" Matsumoto
`mrb_gc_destroy` may call other mruby API functions from the finalizers. So call that function first.
2019-05-25Remove `mrb_alloca()` functiondearblue
When I found this function, I expected it to behave the same as the `alloca(3)` function, but it is accually the `mrb_alloca()` function does not free the heap until the `mrb_close()` function is called. Also, even if it is deleted, it can be replaced with the combination of the `MRB_TT_DATA` object and the `mrb_gv_set()` function if it is sure necessary.
2019-04-03Remove unnecessary `_set_output_format` callKOBAYASHI Shuji
Three-digit exponent issue was fixed via another workaround (63b8f5c).
2019-02-09`mrb_default_allocf()` is default allocator for NULL safedearblue
2019-01-13Use 2 digits exponent format for `printf` family on old MSVCKOBAYASHI Shuji
For conforming C standard.

This patch slightly reduce memory consumption (2% for my test).

2017-11-03Should not use `FSHARED` state for string from `irep` pools; fix #3829Yukihiro "Matz" Matsumoto
This strings in `irep` pools may be freed forcefully in `mrb_irep_free`. This commit probably fixes #3817 as well.
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`.

2017-10-01Add new type of shared string: `RSTR_FSHARED`.Yukihiro "Matz" Matsumoto
`RSTR_FSHARED` use frozen strings as shared body instead of `struct mrb_shared_string`. This reduces allocation from literal strings.

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`.
2017-08-12Reduce integer type mismatch warnings in VC.Yukihiro "Matz" Matsumoto
2017-05-31Revert 4566c80; fix #3679Yukihiro "Matz" Matsumoto
The patch deallocate the memory in `mrb_default_allocf` but that hinders GC in `mrb_realloc`.
2017-05-25Free given pointer if `realloc()` fails; fix #3658Yukihiro "Matz" Matsumoto
2017-05-23Simplify backtrace mechanism; fix #3633 #3634 #3644Yukihiro "Matz" Matsumoto
Instead of preserving a backtrace in `mrb_state`, `mrb_exc_set` keeps packed backtrace in an exception object. `#backtrace` unpacks it to an array of strings.

2015-12-29Support backtrace after method callsKouhei Sutou
GitHub: fix #2902, #2917 The current implementation traverses stack to retrieve backtrace. But stack will be changed when some operations are occurred. It means that backtrace may be broken after some operations. This change (1) saves the minimum information to retrieve backtrace when exception is raised and (2) restores backtrace from the minimum information when backtrace is needed. It reduces overhead for creating backtrace Ruby objects. The space for the minimum information is reused by multiple exceptions. So memory allocation isn't occurred for each exception.

2015-09-12Don't crash if NULL is passed to mrb_closeTatsuhiro Tsujikawa
Sometimes it is very useful just return from mrb_close if NULL is passed as mrb. This is the same spirit of free(3), which just does nothing if NULL is passed.
