2022-03-22[Feature #18634] Implement Arrays on Variable Width AllocationPeter Zhu
This commit implements arrays on Variable Width Allocation. This allows longer arrays to be embedded (i.e. contents directly follow the object header) which improves performance through better cache locality. Notes: Merged: https://github.com/ruby/ruby/pull/5660

A short (2 bytes) will cause unaligned struct accesses when strings are used as a buffer to directly store binary data. Notes: Merged: https://github.com/ruby/ruby/pull/5432

2021-04-13workaround MSVC error卜部昌平
Previous code failed to compile on MSVC. Log: https://github.com/ruby/ruby/pull/4371/checks?check_run_id=2304484466 This is possibly due to the fact that: 1. `Data_Wrap_Struct(...)` appears in a source code 2. which expands to `rb_data_object_wrap(...)` 3. which expands to `RUBY_MACRO_SELECT(rb_data_object_wrap_, RUBY_UNTYPED_DATA_WARNING)` 4. which expands to `rb_data_object_wrap_0` 5. which expands to `rb_data_object_wrap`, so far so good, but 6. this is a recursive macro expansion (see step 2). Everybody stops expanding... - in step 4 for MSVC, and - in step 5 for GCC etc. I have no idea why but this proposed changeset prevents MSVC from stopping at step 4.

2020-10-21Ractor.make_shareable(obj)Koichi Sasada
Introduce new method Ractor.make_shareable(obj) which tries to make obj shareable object. Protocol is here. (1) If obj is shareable, it is shareable. (2) If obj is not a shareable object and if obj can be shareable object if it is frozen, then freeze obj. If obj has reachable objects (rs), do rs.each{|o| Ractor.make_shareable(o)} recursively (recursion is not Ruby-level, but C-level). (3) Otherwise, raise Ractor::Error. Now T_DATA is not a shareable object even if the object is frozen. If the method finished without error, given obj is marked as a sharable object. To allow makng a shareable frozen T_DATA object, then set `RUBY_TYPED_FROZEN_SHAREABLE` as type->flags. On default, this flag is not set. It means user defined T_DATA objects are not allowed to become shareable objects when it is frozen. You can make any object shareable by setting FL_SHAREABLE flag, so if you know that the T_DATA object is shareable (== thread-safe), set this flag, at creation time for example. `Ractor` object is one example, which is not a frozen, but a shareable object.

2020-08-19ROBJECT_IV_INDEX_TBL: convert into an inline function卜部昌平
Former ROBJECT_IV_INDEX_TBL macro included RCLASS_IV_INDEX_TBL, which is not disclosed to extension libraies. The macro was kind of broken. Why not just deprecate it, and convert the internal use into an inline function. Notes: Merged: https://github.com/ruby/ruby/pull/3427
2020-08-15RARRAY_AREF: convert into an inline function卜部昌平
RARRAY_AREF has been a macro for reasons. We might not be able to change that for public APIs, but why not relax the situation internally to make it an inline function. Notes: Merged: https://github.com/ruby/ruby/pull/3419
2020-05-26Use RUBY_DEBUG instead of NDEBUGKoichi Sasada
Assertions in header files slows down an interpreter, so they should be turned off by default (simple `make`). To enable them, define a macro `RUBY_DEBUG=1` (e.g. `make cppflags=-DRUBY_DEBUG` or use `#define` at the very beggining of the file. Note that even if `NDEBUG=1` is defined, `RUBY_DEBUG=1` enables all assertions. [Feature #16837] related: https://github.com/ruby/ruby/pull/3120 `assert()` lines in MRI *.c is not disabled even if `RUBY_DEBUG=0` and it can be disabled with `NDEBUG=1`. So please consider to use `RUBY_ASSERT()` if you want to disable them when `RUBY_DEBUG=0`. Notes: Merged: https://github.com/ruby/ruby/pull/3124
