add #include guard hack According to MSVC manual (*1), cl.exe can skip including a header file when that: - contains #pragma once, or - starts with #ifndef, or - starts with #if ! defined. GCC has a similar trick (*2), but it acts more stricter (e. g. there must be _no tokens_ outside of #ifndef...#endif). Sun C lacked #pragma once for a looong time. Oracle Developer Studio 12.5 finally implemented it, but we cannot assume such recent version. This changeset modifies header files so that each of them include strictly one #ifndef...#endif. I believe this is the most portable way to trigger compiler optimizations.

split internal.h into files One day, I could not resist the way it was written. I finally started to make the code clean. This changeset is the beginning of a series of housekeeping commits. It is a simple refactoring; split internal.h into files, so that we can divide and concur in the upcoming commits. No lines of codes are either added or removed, except the obvious file headers/footers. The generated binary is identical to the one before.

decouple internal.h headers Saves comitters' daily life by avoid #include-ing everything from internal.h to make each file do so instead. This would significantly speed up incremental builds. We take the following inclusion order in this changeset: 1. "ruby/config.h", where _GNU_SOURCE is defined (must be the very first thing among everything). 2. RUBY_EXTCONF_H if any. 3. Standard C headers, sorted alphabetically. 4. Other system headers, maybe guarded by #ifdef 5. Everything else, sorted alphabetically. Exceptions are those win32-related headers, which tend not be self- containing (headers have inclusion order dependencies).

sync RClass::ext::iv_index_tbl iv_index_tbl manages instance variable indexes (ID -> index). This data structure should be synchronized with other ractors so introduce some VM locks. This patch also introduced atomic ivar cache used by set/getinlinecache instructions. To make updating ivar cache (IVC), we changed iv_index_tbl data structure to manage (ID -> entry) and an entry points serial and index. IVC points to this entry so that cache update becomes atomically.

Introduce disposable call-cache. This patch contains several ideas: (1) Disposable inline method cache (IMC) for race-free inline method cache * Making call-cache (CC) as a RVALUE (GC target object) and allocate new CC on cache miss. * This technique allows race-free access from parallel processing elements like RCU. (2) Introduce per-Class method cache (pCMC) * Instead of fixed-size global method cache (GMC), pCMC allows flexible cache size. * Caching CCs reduces CC allocation and allow sharing CC's fast-path between same call-info (CI) call-sites. (3) Invalidate an inline method cache by invalidating corresponding method entries (MEs) * Instead of using class serials, we set "invalidated" flag for method entry itself to represent cache invalidation. * Compare with using class serials, the impact of method modification (add/overwrite/delete) is small. * Updating class serials invalidate all method caches of the class and sub-classes. * Proposed approach only invalidate the method cache of only one ME.

Benchmark code: ```ruby require "benchmark/ips" require_relative "config/environment" Benchmark.ips do |x| x.report "logger" do ActiveRecord::Base.logger end end ``` Ruby 3.0 master / Rails 6.1: ``` Warming up -------------------------------------- logger 155.251k i/100ms Calculating ------------------------------------- ``` Ruby 3.0 with cvar cache / Rails 6.1: ``` Warming up -------------------------------------- logger 1.546M i/100ms Calculating ------------------------------------- logger 14.857M (± 4.8%) i/s - 74.198M in 5.006202s ``` Lastly we ran a benchmark to demonstate the difference between master and our cache when the number of modules increases. This benchmark measures 1 ancestor, 30 ancestors, and 100 ancestors. Ruby 3.0 master: ``` Warming up -------------------------------------- 1 module 1.231M i/100ms 30 modules 432.020k i/100ms 100 modules 145.399k i/100ms Calculating ------------------------------------- 1 module 12.210M (± 2.1%) i/s - 61.553M in 5.043400s 30 modules 4.354M (± 2.7%) i/s - 22.033M in 5.063839s 100 modules 1.434M (± 2.9%) i/s - 7.270M in 5.072531s Comparison: 1 module: 12209958.3 i/s 30 modules: 4354217.8 i/s - 2.80x (± 0.00) slower 100 modules: 1434447.3 i/s - 8.51x (± 0.00) slower ``` Ruby 3.0 with cvar cache: ``` Warming up -------------------------------------- 1 module 1.641M i/100ms 30 modules 1.655M i/100ms 100 modules 1.620M i/100ms Calculating ------------------------------------- 1 module 16.279M (± 3.8%) i/s - 82.038M in 5.046923s 30 modules 15.891M (± 3.9%) i/s - 79.459M in 5.007958s 100 modules 16.087M (± 3.6%) i/s - 81.005M in 5.041931s Comparison: 1 module: 16279458.0 i/s 100 modules: 16087484.6 i/s - same-ish: difference falls within error 30 modules: 15891406.2 i/s - same-ish: difference falls within error ``` Co-authored-by: Aaron Patterson <tenderlove@ruby-lang.org>

Fix origin iclass pointer for modules If a module has an origin, and that module is included in another module or class, previously the iclass created for the module had an origin pointer to the module's origin instead of the iclass's origin. Setting the origin pointer correctly requires using a stack, since the origin iclass is not created until after the iclass itself. Use a hidden ruby array to implement that stack. Correctly assigning the origin pointers in the iclass caused a use-after-free in GC. If a module with an origin is included in a class, the iclass shares a method table with the module and the iclass origin shares a method table with module origin. Mark iclass origin with a flag that notes that even though the iclass is an origin, it shares a method table, so the method table should not be garbage collected. The shared method table will be garbage collected when the module origin is garbage collected. I've tested that this does not introduce a memory leak. This change caused a VM assertion failure, which was traced to callable method entries using the incorrect defined_class. Update rb_vm_check_redefinition_opt_method and find_defined_class_by_owner to treat iclass origins different than class origins to avoid this issue. This also includes a fix for Module#included_modules to skip iclasses with origins. Fixes [Bug #16736]

Ensure origins for all included, prepended, and refined modules This fixes various issues when a module is included in or prepended to a module or class, and then refined, or refined and then included or prepended to a module or class. Implement by renaming ensure_origin to rb_ensure_origin, making it non-static, and calling it when refining a module. Fix Module#initialize_copy to handle origins correctly. Previously, Module#initialize_copy did not handle origins correctly. For example, this code: ```ruby module B; end class A def b; 2 end prepend B end a = A.dup.new class A def b; 1 end end p a.b ``` Printed 1 instead of 2. This is because the super chain for a.singleton_class was: ``` a.singleton_class A.dup B(iclass) B(iclass origin) A(origin) # not A.dup(origin) ``` The B iclasses would not be modified, so the includer entry would be still be set to A and not A.dup. This modifies things so that if the class/module has an origin, all iclasses between the class/module and the origin are duplicated and have the correct includer entry set, and the correct origin is created. This requires other changes to make sure all tests still pass: * rb_undef_methods_from doesn't automatically handle classes with origins, so pass it the origin for Comparable when undefing methods in Complex. This fixed a failure in the Complex tests. * When adding a method, the method cache was not cleared correctly if klass has an origin. Clear the method cache for the klass before switching to the origin of klass. This fixed failures in the autoload tests related to overridding require, without breaking the optimization tests. Also clear the method cache for both the module and origin when removing a method. * Module#include? is fixed to skip origin iclasses. * Refinements are fixed to use the origin class of the module that has an origin. * RCLASS_REFINED_BY_ANY is removed as it was only used in a single place and is no longer needed. * Marshal#dump is fixed to skip iclass origins. * rb_method_entry_make is fixed to handled overridden optimized methods for modules that have origins.

Remove write barrier exemption for T_ICLASS Before this commit, iclasses were "shady", or not protected by write barriers. Because of that, the GC needs to spend more time marking these objects than otherwise. Applications that make heavy use of modules should see reduction in GC time as they have a significant number of live iclasses on the heap. - Put logic for iclass method table ownership into a function - Remove calls to WB_UNPROTECT and insert write barriers for iclasses This commit relies on the following invariant: for any non oirigin iclass `I`, `RCLASS_M_TBL(I) == RCLASS_M_TBL(RBasic(I)->klass)`. This invariant did not hold prior to 98286e9 for classes and modules that have prepended modules. [Feature #16984]
