* internal.h: remove struct method_table_wrapper. struct method_table_wrapper was introduced to avoid duplicate marking for method tables. For example, `module M1; def foo; end; end` make one method table (mtbl) contains a method `foo`. M1 (T_MODULE) points mtbl. Classes C1 and C2 includes M1, then two T_ICLASS objects are created and they points mtbl too. In this case, three objects (one T_MODULE and two T_ICLASS objects) points same mtbl. On marking phase, these three objects mark same mtbl. To avoid such duplication, struct method_table_wrapper was introduced. However, created two T_ICLASS objects have same or shorter lifetime than M1 (T_MODULE) object. So that we only need to mark mtbl from M1, not from T_ICLASS objects. This patch tries marking only from M1. Note that one `Module#prepend` call creates two T_ICLASS objects. One for refering to a prepending Module object, same as `Module#include`. We don't nedd to care this T_ICLASS. One for moving original mtbl from a prepending class. We need to mark such mtbl from this T_ICLASS object. To mark the mtbl, we need to use `RCLASS_ORIGIN(klass)` on marking from a prepended class `klass`. * class.c: ditto. * eval.c (rb_using_refinement): ditto. * gc.c: ditto. * include/ruby/ruby.h: define m_tbl directly. The definition of struct RClass should be moved to (srcdir)/internal.h. * method.h: remove decl of rb_free_m_tbl_wrapper(). * object.c: use RCLASS_M_TBL() directly. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@49862 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* include/ruby/ruby.h: constify RBasic::klass and add RBASIC_CLASS(obj) macro which returns a class of `obj'. This change is a part of RGENGC branch [ruby-trunk - Feature #8339]. * object.c: add new function rb_obj_reveal(). This function reveal interal (hidden) object by rb_obj_hide(). Note that do not change class before and after hiding. Only permitted example is: klass = RBASIC_CLASS(obj); rb_obj_hide(obj); .... rb_obj_reveal(obj, klass); TODO: API design. rb_obj_reveal() should be replaced with others. TODO: modify constified variables using cast may be harmful for compiler's analysis and optimizaton. Any idea to prohibt inserting RBasic::klass directly? If rename RBasic::klass and force to use RBASIC_CLASS(obj), then all codes such as `RBASIC(obj)->klass' will be compilation error. Is it acceptable? (We have similar experience at Ruby 1.9, for example "RARRAY(ary)->ptr" to "RARRAY_PTR(ary)". * internal.h: add some macros. * RBASIC_CLEAR_CLASS(obj) clear RBasic::klass to make it internal object. * RBASIC_SET_CLASS(obj, cls) set RBasic::klass. * RBASIC_SET_CLASS_RAW(obj, cls) same as RBASIC_SET_CLASS without write barrier (planned). * RCLASS_SET_SUPER(a, b) set super class of a. * array.c, class.c, compile.c, encoding.c, enum.c, error.c, eval.c, file.c, gc.c, hash.c, io.c, iseq.c, marshal.c, object.c, parse.y, proc.c, process.c, random.c, ruby.c, sprintf.c, string.c, thread.c, transcode.c, vm.c, vm_eval.c, win32/file.c: Use above macros and functions to access RBasic::klass. * ext/coverage/coverage.c, ext/readline/readline.c, ext/socket/ancdata.c, ext/socket/init.c, * ext/zlib/zlib.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40691 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* internal.h: remove struct method_table_wrapper. struct method_table_wrapper was introduced to avoid duplicate marking for method tables. For example, `module M1; def foo; end; end` make one method table (mtbl) contains a method `foo`. M1 (T_MODULE) points mtbl. Classes C1 and C2 includes M1, then two T_ICLASS objects are created and they points mtbl too. In this case, three objects (one T_MODULE and two T_ICLASS objects) points same mtbl. On marking phase, these three objects mark same mtbl. To avoid such duplication, struct method_table_wrapper was introduced. However, created two T_ICLASS objects have same or shorter lifetime than M1 (T_MODULE) object. So that we only need to mark mtbl from M1, not from T_ICLASS objects. This patch tries marking only from M1. Note that one `Module#prepend` call creates two T_ICLASS objects. One for refering to a prepending Module object, same as `Module#include`. We don't nedd to care this T_ICLASS. One for moving original mtbl from a prepending class. We need to mark such mtbl from this T_ICLASS object. To mark the mtbl, we need to use `RCLASS_ORIGIN(klass)` on marking from a prepended class `klass`. * class.c: ditto. * eval.c (rb_using_refinement): ditto. * gc.c: ditto. * include/ruby/ruby.h: define m_tbl directly.

For example, `module M1; def foo; end; end` make one method table (mtbl) contains a method `foo`. M1 (T_MODULE) points mtbl. Classes C1 and C2 includes M1, then two T_ICLASS objects are created and they points mtbl too. In this case, three objects (one T_MODULE and two T_ICLASS objects) points same mtbl. On marking phase, these three objects mark same mtbl. To avoid such duplication, struct method_table_wrapper was introduced. However, created two T_ICLASS objects have same or shorter lifetime than M1 (T_MODULE) object. So that we only need to mark mtbl from M1, not from T_ICLASS objects. This patch tries marking only from M1. Note that one `Module#prepend` call creates two T_ICLASS objects. One for refering to a prepending Module object, same as `Module#include`. We don't nedd to care this T_ICLASS. One for moving original mtbl from a prepending class. We need to mark such mtbl from this T_ICLASS object.

Note that do not change class before and after hiding. Only permitted example is: klass = RBASIC_CLASS(obj); rb_obj_hide(obj); .... rb_obj_reveal(obj, klass); TODO: API design. rb_obj_reveal() should be replaced with others. TODO: modify constified variables using cast may be harmful for compiler's analysis and optimizaton. Any idea to prohibt inserting RBasic::klass directly? If rename RBasic::klass and force to use RBASIC_CLASS(obj), then all codes such as `RBASIC(obj)->klass' will be compilation error. Is it acceptable? (We have similar experience at Ruby 1.9, for example "RARRAY(ary)->ptr" to "RARRAY_PTR(ary)". * internal.h: add some macros. * RBASIC_CLEAR_CLASS(obj) clear RBasic::klass to make it internal object. * RBASIC_SET_CLASS(obj, cls) set RBasic::klass. * RBASIC_SET_CLASS_RAW(obj, cls) same as RBASIC_SET_CLASS without write barrier (planned). * RCLASS_SET_SUPER(a, b) set super class of a. * array.c, class.c, compile.c, encoding.c, enum.c, error.c, eval.c, file.c, gc.c, hash.c, io.c, iseq.c, marshal.c, object.c, parse.y, proc.c, process.c, random.c, ruby.c, sprintf.c, string.c, thread.c, transcode.c, vm.c, vm_eval.c, win32/file.c: Use above macros and functions to access RBasic::klass. * ext/coverage/coverage.c, ext/readline/readline.c, ext/socket/ancdata.c, ext/socket/init.c, * ext/zlib/zlib.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40691 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* internal.h: remove struct method_table_wrapper. struct method_table_wrapper was introduced to avoid duplicate marking for method tables. For example, `module M1; def foo; end; end` make one method table (mtbl) contains a method `foo`. M1 (T_MODULE) points mtbl. Classes C1 and C2 includes M1, then two T_ICLASS objects are created and they points mtbl too. In this case, three objects (one T_MODULE and two T_ICLASS objects) points same mtbl. On marking phase, these three objects mark same mtbl. To avoid such duplication, struct method_table_wrapper was introduced. However, created two T_ICLASS objects have same or shorter lifetime than M1 (T_MODULE) object. So that we only need to mark mtbl from M1, not from T_ICLASS objects. This patch tries marking only from M1. Note that one `Module#prepend` call creates two T_ICLASS objects. One for refering to a prepending Module object, same as `Module#include`. We don't nedd to care this T_ICLASS. One for moving original mtbl from a prepending class. We need to mark such mtbl from this T_ICLASS object. To mark the mtbl, we need to use `RCLASS_ORIGIN(klass)` on marking from a prepended class `klass`. * class.c: ditto. * eval.c (rb_using_refinement): ditto. * gc.c: ditto. * include/ruby/ruby.h: define m_tbl directly. The definition of struct RClass should be moved to (srcdir)/internal.h. * method.h: remove decl of rb_free_m_tbl_wrapper(). * object.c: use RCLASS_M_TBL() directly. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@49862 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* method.h: introduce rb_callable_method_entry_t to remove rb_control_frame_t::klass. [Bug #11278], [Bug #11279] rb_method_entry_t data belong to modules/classes. rb_method_entry_t::owner points defined module or class. module M def foo; end end In this case, owner is M. rb_callable_method_entry_t data belong to only classes. For modules, MRI creates corresponding T_ICLASS internally. rb_callable_method_entry_t can also belong to T_ICLASS. rb_callable_method_entry_t::defined_class points T_CLASS or T_ICLASS. rb_method_entry_t data for classes (not for modules) are also rb_callable_method_entry_t data because it is completely same data. In this case, rb_method_entry_t::owner == rb_method_entry_t::defined_class. For example, there are classes C and D, and incldues M, class C; include M; end class D; include M; end then, two T_ICLASS objects for C's super class and D's super class will be created. When C.new.foo is called, then M#foo is searcheed and rb_callable_method_t data is used by VM to invoke M#foo. rb_method_entry_t data is only one for M#foo. However, rb_callable_method_entry_t data are two (and can be more). It is proportional to the number of including (and prepending) classes (the number of T_ICLASS which point to the module). Now, created rb_callable_method_entry_t are collected when the original module M was modified. We can think it is a cache. We need to select what kind of method entry data is needed. To operate definition, then you need to use rb_method_entry_t. You can access them by the following functions. * rb_method_entry(VALUE klass, ID id); * rb_method_entry_with_refinements(VALUE klass, ID id); * rb_method_entry_without_refinements(VALUE klass, ID id); * rb_resolve_refined_method(VALUE refinements, const rb_method_entry_t *me); To invoke methods, then you need to use rb_callable_method_entry_t which you can get by the following APIs corresponding to the above listed functions. * rb_callable_method_entry(VALUE klass, ID id); * rb_callable_method_entry_with_refinements(VALUE klass, ID id); * rb_callable_method_entry_without_refinements(VALUE klass, ID id); * rb_resolve_refined_method_callable(VALUE refinements, const rb_callable_method_entry_t *me); VM pushes rb_callable_method_entry_t, so that rb_vm_frame_method_entry() returns rb_callable_method_entry_t. You can check a super class of current method by rb_callable_method_entry_t::defined_class. * method.h: renamed from rb_method_entry_t::klass to rb_method_entry_t::owner. * internal.h: add rb_classext_struct::callable_m_tbl to cache rb_callable_method_entry_t data. We need to consider abotu this field again because it is only active for T_ICLASS. * class.c (method_entry_i): ditto. * class.c (rb_define_attr): rb_method_entry() does not takes defiend_class_ptr. * gc.c (mark_method_entry): mark RCLASS_CALLABLE_M_TBL() for T_ICLASS. * cont.c (fiber_init): rb_control_frame_t::klass is removed. * proc.c: fix `struct METHOD' data structure because rb_callable_method_t has all information. * vm_core.h: remove several fields. * rb_control_frame_t::klass. * rb_block_t::klass.

* method.h: introduce rb_callable_method_entry_t to remove rb_control_frame_t::klass. [Bug #11278], [Bug #11279] rb_method_entry_t data belong to modules/classes. rb_method_entry_t::owner points defined module or class. module M def foo; end end In this case, owner is M. rb_callable_method_entry_t data belong to only classes. For modules, MRI creates corresponding T_ICLASS internally. rb_callable_method_entry_t can also belong to T_ICLASS. rb_callable_method_entry_t::defined_class points T_CLASS or T_ICLASS. rb_method_entry_t data for classes (not for modules) are also rb_callable_method_entry_t data because it is completely same data. In this case, rb_method_entry_t::owner == rb_method_entry_t::defined_class. For example, there are classes C and D, and incldues M, class C; include M; end class D; include M; end then, two T_ICLASS objects for C's super class and D's super class will be created. When C.new.foo is called, then M#foo is searcheed and rb_callable_method_t data is used by VM to invoke M#foo. rb_method_entry_t data is only one for M#foo. However, rb_callable_method_entry_t data are two (and can be more). It is proportional to the number of including (and prepending) classes (the number of T_ICLASS which point to the module). Now, created rb_callable_method_entry_t are collected when the original module M was modified. We can think it is a cache. We need to select what kind of method entry data is needed. To operate definition, then you need to use rb_method_entry_t. You can access them by the following functions. * rb_method_entry(VALUE klass, ID id); * rb_method_entry_with_refinements(VALUE klass, ID id); * rb_method_entry_without_refinements(VALUE klass, ID id); * rb_resolve_refined_method(VALUE refinements, const rb_method_entry_t *me); To invoke methods, then you need to use rb_callable_method_entry_t which you can get by the following APIs corresponding to the above listed functions. * rb_callable_method_entry(VALUE klass, ID id); * rb_callable_method_entry_with_refinements(VALUE klass, ID id); * rb_callable_method_entry_without_refinements(VALUE klass, ID id); * rb_resolve_refined_method_callable(VALUE refinements, const rb_callable_method_entry_t *me); VM pushes rb_callable_method_entry_t, so that rb_vm_frame_method_entry() returns rb_callable_method_entry_t. You can check a super class of current method by rb_callable_method_entry_t::defined_class. * method.h: renamed from rb_method_entry_t::klass to rb_method_entry_t::owner. * internal.h: add rb_classext_struct::callable_m_tbl to cache rb_callable_method_entry_t data. We need to consider abotu this field again because it is only active for T_ICLASS. * class.c (method_entry_i): ditto. * class.c (rb_define_attr): rb_method_entry() does not takes defiend_class_ptr. * gc.c (mark_method_entry): mark RCLASS_CALLABLE_M_TBL() for T_ICLASS. * cont.c (fiber_init): rb_control_frame_t::klass is removed. * proc.c: fix `struct METHOD' data structure because rb_callable_method_t has all information. * vm_core.h: remove several fields. * rb_control_frame_t::klass. * rb_block_t::klass. And catch up changes. * eval.c: catch up changes. * gc.c: ditto. * insns.def: ditto. * vm.c: ditto. * vm_args.c: ditto. * vm_backtrace.c: ditto. * vm_dump.c: ditto. * vm_eval.c: ditto. * vm_insnhelper.c: ditto. * vm_method.c: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51126 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
