* M:N thread scheduler for RactorsKoichi Sasada2023-10-121-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduce M:N thread scheduler for Ractor system. In general, M:N thread scheduler employs N native threads (OS threads) to manage M user-level threads (Ruby threads in this case). On the Ruby interpreter, 1 native thread is provided for 1 Ractor and all Ruby threads are managed by the native thread. From Ruby 1.9, the interpreter uses 1:1 thread scheduler which means 1 Ruby thread has 1 native thread. M:N scheduler change this strategy. Because of compatibility issue (and stableness issue of the implementation) main Ractor doesn't use M:N scheduler on default. On the other words, threads on the main Ractor will be managed with 1:1 thread scheduler. There are additional settings by environment variables: `RUBY_MN_THREADS=1` enables M:N thread scheduler on the main ractor. Note that non-main ractors use the M:N scheduler without this configuration. With this configuration, single ractor applications run threads on M:1 thread scheduler (green threads, user-level threads). `RUBY_MAX_CPU=n` specifies maximum number of native threads for M:N scheduler (default: 8). This patch will be reverted soon if non-easy issues are found. [Bug #19842]

* use inline cache for refinementsKoichi Sasada2023-07-311-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From Ruby 3.0, refined method invocations are slow because resolved methods are not cached by inline cache because of conservertive strategy. However, `using` clears all caches so that it seems safe to cache resolved method entries. This patch caches resolved method entries in inline cache and clear all of inline method caches when `using` is called. fix [Bug #18572] ```ruby # without refinements class C def foo = :C end N = 1_000_000 obj = C.new require 'benchmark' Benchmark.bm{|x| x.report{N.times{ obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; }} } _END__ user system total real master 0.362859 0.002544 0.365403 ( 0.365424) modified 0.357251 0.000000 0.357251 ( 0.357258) ``` ```ruby # with refinment but without using class C def foo = :C end module R refine C do def foo = :R end end N = 1_000_000 obj = C.new require 'benchmark' Benchmark.bm{|x| x.report{N.times{ obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; }} } __END__ user system total real master 0.957182 0.000000 0.957182 ( 0.957212) modified 0.359228 0.000000 0.359228 ( 0.359238) ``` ```ruby # with using class C def foo = :C end module R refine C do def foo = :R end end N = 1_000_000 using R obj = C.new require 'benchmark' Benchmark.bm{|x| x.report{N.times{ obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; obj.foo; }} }
* Ensure throw data is not set as causePeter Zhu2023-04-131-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | [Bug #19593] rb_ec_setup_exception did not check if errinfo is a throw_data. This can cause crashes in code since it is assumed that id_cause is an object. We saw a crash in show_cause due to id_cause of errinfo being a throw_data. It crashes on rb_obj_is_kind_of since it cannot be called on T_IMEMO objects. Unfortunately, we couldn't find a reproduction script, however we debugged the core dump and rb_ec_setup_exception is the only place where id_cause is assigned from errinfo without checking if it is a throw_data. ``` 0x0000556c5708e6dd in sigsegv (sig=11, info=0x7f301befa3f0, ctx=0x7f301befa2c0) at signal.c:964 0x00007f301d046420 in <signal handler called> () at /lib/x86_64-linux-gnu/libpthread.so.0 class_search_class_ancestor (c=139844586301760, cl=<optimized out>) at object.c:810 rb_obj_is_kind_of (obj=obj@entry=139839221734880, c=139844586301760) at object.c:861 0x0000556c56f2f00f in show_cause (errinfo=errinfo@entry=139838840645160, str=str@entry=139839221730520, opt=139839221730480, highlight=0, reverse=reverse@entry=0, backtrace_limit=backtrace_limit@entry=-1, shown_causes=0x7ffe9d1a2d68) at ./include/ruby/internal/special_consts.h:175 ``` Co-Authored-By: Jean Boussier <byroot@ruby-lang.org>

| | | | | | | | | Right now the attached object is stored as an instance variable and all the call sites that either get or set it have to know how it's stored. It's preferable to hide this implementation detail behind accessors so that it is easier to change how it's stored.

* MJIT: Stop using the VM barrier for jit_contTakashi Kokubun2022-10-191-1/+2
| | | | | | | | | | | | | | | | This solves multiple problems. First, RB_VM_LOCK_ENTER/LEAVE is a barrier. We could at least use the _NO_BARRIER variant. Second, this doesn't need to interfere with GC or other GVL users when multiple Ractors are used. This needs to be used in very few places, so the benefit of fine-grained locking would outweigh its small maintenance cost. Third, it fixes a crash for YJIT. Because YJIT is never disabled until a process exits unlike MJIT that finishes earlier, we could call jit_cont_free when EC no longer exists, which crashes RB_VM_LOCK_ENTER.
