2022-09-26This 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.

2022-09-26string.c: don't create a frozen copy for str_new_sharedJean Boussier
str_new_shared already has all the necessary logic to do this and is also smart enough to skip this step if the source string is already a shared string itself. This saves a useless String allocation on each call. Notes: Merged: https://github.com/ruby/ruby/pull/6443
2022-09-26Fix coderange calculation in String#bKazuki Yamaguchi
Leave the new coderange unknown if the original encoding is not ASCII-compatible. Non-ASCII-compatible encoding strings with valid or broken coderange can end up as ascii-only. Fixes 9a8f6e392fbd ("Cheaply derive code range for String#b return value", 2022-07-25).

2022-09-26Generate the revision.h before MakefileNobuyoshi Nakada
Except for GNU make which updates makefiles automatically, repeating configure in the same directory causes `make` to stop whenever pulled a new commit. This is unexpected in CIs. Notes: Merged: https://github.com/ruby/ruby/pull/6436
2022-09-25[Bug #19021] Fix safe call w/ conditional assignJohn Hawthorn
As of fbaac837cfba23a9d34dc7ee144d7940248222a2, when we were performing a safe call (`o&.x=`) with a conditional assign (`||= 1`) and discarding the result the stack would end up in a bad state due to a missing pop. This commit fixes that by adjusting the target label of the branchnil to be before a pop in that case (as was previously done in the non-conditional assignment case).

2022-09-26Initialize Objective-C classes before fork() for macOS 13Yuta Saito
Since macOS 13, CFString family API used in `rb_str_append_normalized_ospath` may internally use Objective-C classes (`NSTaggedPointerString` and `NSPlaceholderMutableString`) for small strings. On the other hand, Objective-C classes should not be used for the first time in a `fork()`'ed but not `exec()`'ed process. Violations for this rule can result deadlock during class initialization, so Objective-C runtime conservatively crashes on such cases by default. Therefore, we need to use CFString API to initialize Objective-C classes used internally *before* `fork()`. For more details, see https://bugs.ruby-lang.org/issues/18912 Notes: Merged: https://github.com/ruby/ruby/pull/6426
