Some `undef' functions may be called before initialization, thus causes
infinite error recursion.
|
|
|
|
Avoid calling `initialize` via `mrb_funcall`, which cause `cross C
boundary` error from Fibers started in the method.
|
|
* `mrb_vm_define_class`
* `mrb_vm_define_module`
Only functions called from user code requires `MRB_API`.
|
|
Contrary to the name, `mrb_to_str` just checks type, no conversion.
|
|
`mrb_string_value_cstr` and `mrb_string_value_len`: obsolete
`mrb_string_cstr`: new function to retrieve NULL terminated C string
`RSTRING_CSTR`: wrapper macro of `mrb_string_cstr`

The binary sizes (gems are only `mruby-bin-mruby`) are reduced slightly in
my environment than before the introduction of new specifiers/modifiers
(5116789a) with this change.

BTW, I accidentally changed `tasks/toolchains/visualcpp.rake` at #4613,
so I put it back.

Before this patch:
$ bin/mruby -e 'p Module.new.freeze.dup.frozen?' #=> true
After this patch (same as Ruby):
$ bin/mruby -e 'p Module.new.freeze.dup.frozen?' #=> false
|
|
Also integrated the common parts of `mrb_mod_attr_reader()` and
`mrb_mod_attr_writer()` functions.

Before this patch:
$ bin/mruby -e 'p Struct.new("A-")'
#=> Struct::"A-"
After this patch:
$ bin/mruby -e 'p Struct.new("A-")'
#=> NameError: identifier A- needs to be constant

Fix name assignment to frozen anonymous class/module

Before this patch:
p (class << Object.new.freeze; self end).frozen? #=> false
sc = class << (o=Object.new); self end; o.freeze; p sc.frozen? #=> false
After this patch / Ruby:
p (class << Object.new.freeze; self end).frozen? #=> true
sc = class << (o=Object.new); self end; o.freeze; p sc.frozen? #=> true
|
|
Fix the following issues:
A = Class.new.freeze #=> FrozenError
Module.new::B = Class.new.freeze #=> FrozenError
String::B = Module.new.freeze #=> FrozenError

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.

Functions to add prototypes to headers:
* mrb_ary_splice()
* mrb_notimplement()
* mrb_vformat()
* mrb_cstr_to_dbl()
* mrb_cstr_to_inum()
Functions to be made `static` (`MRB_API` was not needed):
* mrb_mod_module_function()
* mrb_obj_hash()
* mrb_str_len_to_inum()
Functions to remove `MRB_API` from definitions (referenced from within `libmruby`):
* mrb_mod_cv_defined()
* mrb_mod_cv_get()
* mrb_f_send()

`X!` etc are invalid constant name.

We have added internal convenience method `__to_str` which
does string type check.
The issue #3854 was fixed but fundamental flaw of lack of stack
depth check along with fibers still remains. Use `MRB_GC_FIXED_ARENA`
for workaround.

Fix outer module name
|
|
example:
a = Module.new
a::B = Module.new
p [a, a::B] # => [#<Module:0x801825890>, #<Class:0x801825890>::B]
# => [#<Module:0x801825890>, #<Module:0x801825890>::B] (Fixed)
|
|
example:
a = Class.new
a::A = a

This change was inspired by [ruby-bugs#7573]

We assume meta-programming is less used in embedded environments.
We have moved following methods:
* Kernel module
global_variables, local_variables, singleton_class,
instance_variables, instance_variables_defined?, instance_variable_get,
instance_variable_set, methods, private_methods, public_methods,
protected_methods, singleton_methods, define_singleton_methods
* Module class
class_variables, class_variables_defined?, class_variable_get,
class_variable_set, remove_class_variable, included_modules,
instance_methods, remove_method, method_removed, constants
* Module class methods
constants, nesting
Note:
Following meta-programming methods are kept in the core:
* Module class
alias_method, undef_method, ancestors, const_defined?, const_get,
const_set, remove_const, method_defined?, define_method
* Toplevel object
define_method
`mruby-metaprog` gem is linked by default (specified in default.gembox).
When it is removed, it will save 40KB (stripped:8KB) on x86-64
environment last time I measured.

`mrb_iv_p` -> `mrb_iv_name_sym_p`

Renamed flag macro names as well:
`MRB_FLAG_IS_FROZEN` -> `MRB_FL_OBJ_FROZEN`
`MRB_FLAG_IS_PREPENDED` -> `MRB_FL_CLASS_IS_PREPENDED`
`MRB_FLAG_IS_ORIGIN` -> `MRB_FL_CLASS_IS_ORIGIN`
`MRB_FLAG_IS_INHERITED` -> `MRB_FL_CLASS_IS_INHERITED`
