2022-11-25add debug context APIs for debuggers (frame depth)Koichi Sasada
The following new debug context APIs are for implementing debugger's `next` (step over) and similar functionality. * `rb_debug_inspector_frame_depth(dc, index)` returns `index`-th frame's depth. * `rb_debug_inspector_current_depth()` returns current frame depth. The frame depth is not related to the frame index because debug context API skips some special frames but proposed `_depth()` APIs returns the count of all frames (raw depth).

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.

2022-11-17Add support for `sockaddr_un` on Windows. (#6513)Samuel Williams
* Windows: Fix warning about undefined if_indextoname() * Windows: Fix UNIXSocket on MINGW and make .pair more reliable * Windows: Use nonblock=true for read tests with scheduler * Windows: Move socket detection from File.socket? to File.stat Add S_IFSOCK to Windows and interpret reparse points accordingly. Enable tests that work now. * Windows: Use wide-char functions to UNIXSocket This fixes behaviour with non-ASCII characters. It also fixes deletion of temporary UNIXSocket.pair files. * Windows: Add UNIXSocket tests for specifics of Windows impl. * Windows: fix VC build due to missing _snwprintf Avoid usage of _snwprintf, since it fails linking ruby.dll like so: linking shared-library x64-vcruntime140-ruby320.dll x64-vcruntime140-ruby320.def : error LNK2001: unresolved external symbol snwprintf x64-vcruntime140-ruby320.def : error LNK2001: unresolved external symbol vsnwprintf_l whereas linking miniruby.exe succeeds. This patch uses snprintf on the UTF-8 string instead. Also remove branch GetWindowsDirectoryW, since it doesn't work. * Windows: Fix dangling symlink test failures Co-authored-by: Lars Kanis <kanis@comcard.de> Notes: Merged-By: ioquatix <samuel@codeotaku.com>
2022-11-17Windows: Readlink improvements (#6745)Lars Kanis
* Windows: Use readlink emulation for File.readlink This fixes readlink emulation for the ERROR_MORE_DATA case and general error reporting. It now releases GVL while readlink IO operation. The dedicated rb_readlink was introduced in commit 2ffb87995a33cdc7ba609a4b867f03f18da0c3b3 in order to improve encoding and buffer allocation. However the encoding issues are solved since ruby-3.0 switched to UTF-8 and the buffer allocation will be improved in a later commit. * Windows: Increase the default buffer size for reparse point info So far nearly all queries of reparse points needed two attempts to get enough buffer. * Windows: Remove declaration of rb_w32_wreadlink It was removed in commit 2f6fdd3aebdee2ce04d003b206f6da78120e8235 Notes: Merged-By: ioquatix <samuel@codeotaku.com>
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

2022-10-25Prevent potential buffer overrun in onigmoYusuke Endoh
A code pattern `p + enclen(enc, p, pend)` may lead to a buffer overrun if incomplete bytes of a UTF-8 character is placed at the end of a string. Because this pattern is used in several places in onigmo, this change fixes the issue in the side of `enclen`: the function should not return a number that is larger than `pend - p`.

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
