[Bug #19289] Retain `ruby_abi_version` function A few extension libraries, to hide all symbols except for necessary to load, hardcode the symbols to be exported in symbol list files for linker without even checking by `have_func`. As a workaround for such libraries, retain `ruby_abi_version` symbol always even in released versions for now. --- include/ruby/internal/abi.h | 7 +++++-- 1 file changed, 5 insertions(+), 2 deletions(-)

2022-11-17Refactor RB_SPECIAL_CONST_P (#6759)Takashi Kokubun
Since https://github.com/ruby/ruby/pull/6599, RUBY_IMMEDIATE_MASK also overlaps RUBY_Qnil. Now RB_SPECIAL_CONST_P seems confusing since both RB_IMMEDIATE_P and RB_TEST check for RUBY_Qnil while we only need to check RUBY_Qnil besides RUBY_IMMEDIATE_MASK. I'd like to make this change to make it less confusing. I confirmed that this doesn't change the number of instructions used for the RUBY_Qfalse check on Linux x86_64 GCC and macOS arm64 Clang.

2022-11-10Remove numiv from RObjectJemma Issroff
Since object shapes store the capacity of an object, we no longer need the numiv field on RObjects. This gives us one extra slot which we can use to give embedded objects one more instance variable (for a total of 3 ivs). This commit removes the concept of numiv from RObject. Notes: Merged: https://github.com/ruby/ruby/pull/6699
2022-11-10Transition shape when object's capacity changesJemma Issroff
This commit adds a `capacity` field to shapes, and adds shape transitions whenever an object's capacity changes. Objects which are allocated out of a bigger size pool will also make a transition from the root shape to the shape with the correct capacity for their size pool when they are allocated. This commit will allow us to remove numiv from objects completely, and will also mean we can guarantee that if two objects share shapes, their IVs are in the same positions (an embedded and extended object cannot share shapes). This will enable us to implement ivar sets in YJIT using object shapes. Co-Authored-By: Aaron Patterson <tenderlove@ruby-lang.org> Notes: Merged: https://github.com/ruby/ruby/pull/6699

2022-09-30Revert "This commit implements the Object Shapes technique in CRuby."Aaron Patterson
This reverts commit 68bc9e2e97d12f80df0d113e284864e225f771c2.
2022-09-28This commit implements the Object Shapes technique in CRuby.Jemma Issroff
Object Shapes is used for accessing instance variables and representing the "frozenness" of objects. Object instances have a "shape" and the shape represents some attributes of the object (currently which instance variables are set and the "frozenness"). Shapes form a tree data structure, and when a new instance variable is set on an object, that object "transitions" to a new shape in the shape tree. Each shape has an ID that is used for caching. The shape structure is independent of class, so objects of different types can have the same shape. For example: ```ruby class Foo def initialize # Starts with shape id 0 @a = 1 # transitions to shape id 1 @b = 1 # transitions to shape id 2 end end class Bar def initialize # Starts with shape id 0 @a = 1 # transitions to shape id 1 @b = 1 # transitions to shape id 2 end end foo = Foo.new # `foo` has shape id 2 bar = Bar.new # `bar` has shape id 2 ``` Both `foo` and `bar` instances have the same shape because they both set instance variables of the same name in the same order. This technique can help to improve inline cache hits as well as generate more efficient machine code in JIT compilers. This commit also adds some methods for debugging shapes on objects. See `RubyVM::Shape` for more details. For more context on Object Shapes, see [Feature: #18776] Co-Authored-By: Aaron Patterson <tenderlove@ruby-lang.org> Co-Authored-By: Eileen M.

2022-08-19Support Encoding::Converter newline: :lf and :lf_newline optionsJeremy Evans
Previously, newline: :lf was accepted but ignored. Where it should have been used was commented out code that didn't work, but unlike all other invalid values, using newline: :lf did not raise an error. This adds support for newline: :lf and :lf_newline, for consistency with newline: :cr and :cr_newline. This is basically the same as universal_newline, except that it only affects writing and not reading due to RUBY_ECONV_NEWLINE_DECORATOR_WRITE_MASK. Add tests for the File.open :newline option while here. Fixes [Bug #12436] Notes: Merged: https://github.com/ruby/ruby/pull/4590

2022-06-10Make method id explicit in rb_exec_recursive_outerJohn Hawthorn
Previously, because opt_aref and opt_aset don't push a frame, when they would call rb_hash to determine the hash value of the key, the initial level of recursion would incorrectly use the method id at the top of the stack instead of "hash". This commit replaces rb_exec_recursive_outer with rb_exec_recursive_outer_mid, which takes an explicit method id, so that we can make the hash calculation behave consistently. rb_exec_recursive_outer was documented as being internal, so I believe this should be okay to change.
