2022-05-09Increase SIZE_POOL_COUNT to 5Peter Zhu
Having more size pools will allow us to allocate larger objects through Variable Width Allocation. I have attached some benchmark results below.

2022-04-26Expose `rb_hash_new_capa(long)`Jean Boussier
[Feature #18683] This allows parsers and similar libraries to create Hashes of a certain capacity in advance. It's useful when the key and values are streamed, hence `bulk_insert()` can't be used. Notes: Merged: https://github.com/ruby/ruby/pull/5835

2022-04-01Finer-grained constant cache invalidation (take 2)Kevin Newton
This commit reintroduces finer-grained constant cache invalidation. After 8008fb7 got merged, it was causing issues on token-threaded builds (such as on Windows). The issue was that when you're iterating through instruction sequences and using the translator functions to get back the instruction structs, you're either using `rb_vm_insn_null_translator` or `rb_vm_insn_addr2insn2` depending if it's a direct-threading build. `rb_vm_insn_addr2insn2` does some normalization to always return to you the non-trace version of whatever instruction you're looking at. `rb_vm_insn_null_translator` does not do that normalization. This means that when you're looping through the instructions if you're trying to do an opcode comparison, it can change depending on the type of threading that you're using. This can be very confusing. So, this commit creates a new translator function `rb_vm_insn_normalizing_translator` to always return the non-trace version so that opcode comparisons don't have to worry about different configurations.

2022-03-24Finer-grained inline constant cache invalidationKevin Newton
Current behavior - caches depend on a global counter. All constant mutations cause caches to be invalidated. ```ruby class A B = 1 end def foo A::B # inline cache depends on global counter end foo # populate inline cache foo # hit inline cache C = 1 # global counter increments, all caches are invalidated foo # misses inline cache due to `C = 1` ``` Proposed behavior - caches depend on name components. Only constant mutations with corresponding names will invalidate the cache. ```ruby class A B = 1 end def foo A::B # inline cache depends constants named "A" and "B" end foo # populate inline cache foo # hit inline cache C = 1 # caches that depend on the name "C" are invalidated foo # hits inline cache because IC only depends on "A" and "B" ``` Examples of breaking the new cache: ```ruby module C # Breaks `foo` cache because "A" constant is set and the cache in foo depends # on "A" and "B" class A; end end B = 1 ``` We expect the new cache scheme to be invalidated less often because names aren't frequently reused. With the cache being invalidated less, we can rely on its stability more to keep our constant references fast and reduce the need to throw away generated code in YJIT.

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

2022-02-22[Feature #18249] Implement ABI checkingPeter Zhu
Header file include/ruby/internal/abi.h contains RUBY_ABI_VERSION which is the ABI version. This value should be bumped whenever an ABI incompatible change is introduced. When loading dynamic libraries, Ruby will compare its own `ruby_abi_version` and the `ruby_abi_version` of the loaded library. If these two values don't match it will raise a `LoadError`. This feature can also be turned off by setting the environment variable `RUBY_RUBY_ABI_CHECK=0`. This feature will prevent cases where previously installed native gems fail in unexpected ways due to incompatibility of changes in header files. This will force the developer to recompile their gems to use the same header files as the built Ruby. In Ruby, the ABI version is exposed through `RbConfig::CONFIG["ruby_abi_version"]`.

2022-02-19Define `HAVE___BUILTIN_UNREACHABLE` instead of `UNREACHABLE`Nobuyoshi Nakada
`UNREACHABLE` in ruby/internal/has/builtin.h is only used as just a flag now, and redefined in ruby/backward/2/assume.h then. Notes: Merged: https://github.com/ruby/ruby/pull/5577
2022-01-20Mark `rb_clear_constant_cache` as internal use onlyNobuyoshi Nakada
In the past, many internal functions are declared in intern.h under include/ruby directory, because there were no headers for internal use.
2022-01-19include/ruby/win32.h: explicitly define HAVE_SHUTDOWNYuta Saito
Configuration for mingw32 can't detect 'shutdown' due to wrong -l option even though it's available (this has been going on for a while, and it needs to be fixed). In this situation, include/ruby/missing.h declares a stub shutdown function since 7ee786388a, and another shutdown decl is came from system header. They are incompatible at stdcall attribute, so it causes compilation failure. This change defines a HAVE_SHUTDOWN to guard a newly introduced stub decl in include/ruby/missing.h Notes: Merged: https://github.com/ruby/ruby/pull/5465
2022-01-19include/ruby/io.h: use 0 as POLLPRI when no support for itYuta Saito
0x003 is not suitable as a bit mask, and it's ok just to be 0 to avoid setting unsupported bit. Notes: Merged: https://github.com/ruby/ruby/pull/5461
2022-01-19[wasm] include/ruby/io.h: define RB_WAITFD_PRI by ourselves for wasiYuta Saito
RB_WAITFD_PRI uses POLLPRI for other platforms, but wasi-libc doesn't have POLLPRI for now. Notes: Merged: https://github.com/ruby/ruby/pull/5407
2022-01-19[wasm] add no thread variant for freestanding environmentYuta Saito
This implementation does nothing around preemptive context switching because there is no native thread. Notes: Merged: https://github.com/ruby/ruby/pull/5407

2022-01-18Don't assume __builtin_bswap32 and __builtin_bswap64 are defined on OpenBSDJeremy Evans
At least OpenBSD/sparc64 doesn't appear to define them, and possibly some other OpenBSD GCC platforms don't (most OpenBSD platforms have already switched to clang).
2022-01-18[Feature #18491] Drop support for HP-UXPeter Zhu
