2021-07-17Explicit write barrier for bindingdearblue
2021-06-26Fixed finding variables from `proc` in `binding.eval` faileddearblue
Previously the following code did not produce the expected results: ```ruby bx = binding block = bx.eval("a = 1; proc { a }") bx.eval("a = 2") p block.call # Expect 2 but return 1 due to a bug ``` The previous implementation of `Binding#eval` evaluated the code and then merged the top layer variables. This patch will parse and expand the variable space before making a call to `eval`. This means that the call to `Binding#eval` will do the parsing twice. In addition, the following changes will be made: - Make `mrb_parser_foreach_top_variable()`, `mrb_binding_extract_proc()` and `mrb_binding_extract_env()` functions private global functions. - Remove the `posthook` argument from `mrb_exec_irep()`. The `posthook` argument was introduced to implement the `binding` method. This patch is unnecessary because it uses a different implementation method. ref #5362 fixed #5491
2021-06-20Added `MRB_OBJ_ALLOC()` macro that does not require a castdearblue
The `MRB_OBJ_ALLOC()` macro function returns a pointer of the type corresponding to the constant literal defined in `enum mrb_vtype`.
2021-04-24Introduce `MRB_GC_RED`dearblue
Replaces the magic number `7` except in `src/gc.c`.
2021-04-04Making a proc object static for a method with static irepdearblue
The following methods will be made static. - `Class#new` - `Proc#call` - `Kernel#catch` Previously, static const RProc could not be registered as a method, but this has been changed to allow it.
2021-02-28Remove periods from error messages according to the convention.Yukihiro "Matz" Matsumoto
2021-02-22Added other methods for `Binding`dearblue
- Added to `mruby-binding-core` - `Binding#local_variable_defined?` - `Binding#local_variable_get` - `Binding#local_variable_set` - `Binding#local_variables` - `Binding#receiver` - `Binding#source_location` - `Binding#inspect` - Added to `mruby-proc-binding` - `Proc#binding` The reason for separating `Proc#binding` is that core-mrbgems has a method that returns a closure object to minimize possible problems with being able to manipulate internal variables. By separating it as different mrbgem, each user can judge this problem and incorporate it arbitrarily.
2021-02-22Adjustment of the current HEAD and bindings, and separationdearblue
Make changes to make `Binding` work. At the same time, it separates `Binding#eval`, which depends on `mruby-eval`, from `mruby-binding-core`.
2021-01-26Revert "Minimize the changes in #5277"Yukihiro "Matz" Matsumoto
This reverts commit dc51d89ac22acc60b9bfeed87115863565b74085.
2021-01-22Minimize the changes in #5277Yukihiro "Matz" Matsumoto
Instead of including `mruby/presym.h` everywhere, we provided the fallback `mruby/presym.inc` under `include/mruby` directory, and specify `-I<build-dir>/include` before `-I<top-dir>/include` in `presym.rake`. So even when someone drops `-I<build-dir>/include` in compiler options, it just compiles without failure.

2021-01-11Avoid including `presym.inc` in existing header filesKOBAYASHI Shuji
Addressed an issue where existing programs linking `libmruby.a` could only be built by adding `<build-dir>/include` to compiler's include path.
2021-01-10Replace `tempirep` with `RProc`dearblue
Previously I used the `RData` object to avoid a memory leak in `mrb_irep` if `src/load.c` failed. ref: https://github.com/mruby/mruby/pull/4250 commit: f1523d24042ca3416dc5b9be7b3fc220ddaed896 Considering that the `RProc` object will be created in the subsequent process, it is preferable to create the `RProc` object from the beginning. Along with this, the inside of `read_irep()` is replaced with the processing centered on the `RProc` object. The global function that returns the `mrb_irep` pointer is still provided for compatibility.
2021-01-10Changes `stackent` to `stack` of `mrb_callinfo`dearblue
This enhances self-containment. Previously `mrb_context::stack` had the current call level stack, but now it owns it. The `mrb_context::stack` field, which is no longer needed, will be removed.
2021-01-10Unified `target_class` and `env` of `mrb_callinfo`dearblue
If there is `env`, `env->c` means `target_class`.
2020-11-13Change name and usage of presym macrosKOBAYASHI Shuji
To be also able to build mruby without presym in the future. However, `MRB_QSYM` has been removed and changed as follows: ### Example | Type | Symbol | Previous Style | New Style | |---------------------------|--------|------------------|----------------| | Operator | & | MRB_QSYM(and) | MRB_OPSYM(and) | | Class Variable | @@foo | MRB_QSYM(00_foo) | MRB_CVSYM(foo) | | Instance Variable | @foo | MRB_QSYM(0_foo) | MRB_IVSYM(foo) | | Method with Bang | foo! | MRB_QSYM(foo_b) | MRB_SYM_B(foo) | | Method with Question mark | foo? | MRB_QSYM(foo_p) | MRB_SYM_Q(foo) | | Mmethod with Equal | foo= | MRB_QSYM(foo_e) | MRB_SYM_E(foo) | This change makes it possible to define, for example, `MRB_IVSYM(foo)` as `mrb_intern_lit(mrb, "@" "foo")`, which is useful if we support building without presym in the future.
2020-10-24Reorganize `env_new()` as `mrb_env_new()`dearblue
The `mrb_env_new()` function is a global function, but it is still treated as an internal function.

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()`
2019-09-26Use type predicate macros instead of `mrb_type` if possibleKOBAYASHI Shuji

2019-09-18Fix `super` from aliased methods to work correctly; fix #4718Yukihiro "Matz" Matsumoto
We needed to preserve the original method name somewhere. We kept it in the `env` structure pointed from aliased methods. #1457 and #1531 tried to address this issue. But this patch is more memory efficient. Limitation: this fix does not support `super` from methods defined by `define_method`. This limitation may be addressed in the future, but it's low priority.

2017-11-20Add `MRB_METHOD_TABLE_INLINE` option.Yukihiro "Matz" Matsumoto
Now the method tables (in classes/modules and caches) keeps C function pointers without wrapping in `struct RProc` objects. For the sake of portability, `mrb_method_t` is represented by the struct and union, but if the most significant bit of the pointer is not used by the platform, `mrb_method_t` should be packed in `uintptr_t` to reduce memory usage. `MRB_METHOD_TABLE_INLINE` is turned on by default for linux.
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`.
