* Introduce Ractor mechanism for parallel executionKoichi Sasada2020-09-031-1/+2
| | | | | | | | | | | | | | | | This commit introduces Ractor mechanism to run Ruby program in parallel. See doc/ractor.md for more details about Ractor. See ticket [Feature #17100] to see the implementation details and discussions. [Feature #17100] This commit does not complete the implementation. You can find many bugs on using Ractor. Also the specification will be changed so that this feature is experimental. You will see a warning when you make the first Ractor with `Ractor.new`. I hope this feature can help programmers from thread-safety issues.
* Remove write barrier exemption for T_ICLASSAlan Wu2020-08-171-2/+1
| | | | | | | | | | | | | | | | | | | 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]
* Lazily insert origins on prepend to save memoryAlan Wu2020-07-221-3/+0
| | | | | | | | | | | | | | | | 98286e9850936e27e8ae5e4f20858cc9c13d2dde made it so that `Module#include` allocates an origin iclass on each use. Since `include` is widely used, the extra allocation can contribute significantly to memory usage. Instead of always allocating in anticipation of prepend, this change takes a different approach. The new setup inserts a origin iclass into the super chains of all the children of the module when prepend happens for the first time. rb_ensure_origin is made static again since now that adding an origin now means walking over all usages, we want to limit the number of places where we do it.
* rb_class_modify_check: add UNREACHABLE卜部昌平2020-06-291-0/+1
| | | | | | | | (I was not aware of this because I use clang, but) it seems gcc cannot detect reachablility of this point. It renders an unused variable warning, which is a false positive. Let us suppress the compiler. https://github.com/ruby/ruby/runs/816997191#step:9:62

* Ensure origins for all included, prepended, and refined modulesJeremy Evans2020-06-031-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Clear all trace events during teardownAlan Wu2020-03-291-1/+2
| | | | | | | | | | | Since 0c2d81dada, not all trace events are cleared during VM teardown. This causes a crash when there is a tracepoint for `RUBY_INTERNAL_EVENT_GC_EXIT` active during teardown. The commit looks like a refactoring commit so I think this change was unintentional. [Bug #16682]

* Introduce disposable call-cache.Koichi Sasada2020-02-221-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. See [Feature #16614] for more details.
* Fully separate positional arguments and keyword argumentsJeremy Evans2020-01-021-8/+0
| | | | | | | | | | | | | | | | | | | | | | | | This removes the warnings added in 2.7, and changes the behavior so that a final positional hash is not treated as keywords or vice-versa. To handle the arg_setup_block splat case correctly with keyword arguments, we need to check if we are taking a keyword hash. That case didn't have a test, but it affects real-world code, so add a test for it. This removes rb_empty_keyword_given_p() and related code, as that is not needed in Ruby 3. The empty keyword case is the same as the no keyword case in Ruby 3. This changes rb_scan_args to implement keyword argument separation for C functions when the : character is used. For backwards compatibility, it returns a duped hash. This is a bad idea for performance, but not duping the hash breaks at least Enumerator::ArithmeticSequence#inspect. Instead of having RB_PASS_CALLED_KEYWORDS be a number, simplify the code by just making it be rb_keyword_given_p().
* decouple internal.h headers卜部昌平2019-12-261-7/+19
| | | | | | | | | | | | | | | | | | 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).
* Kernel#abort without arguments should print error infoNobuyoshi Nakada2019-12-161-3/+3

* Make prepending a refined module after inclusion not break refinementsJeremy Evans2019-11-281-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | After the previous commit, this was still broken. The reason it was broken is that a refined module that hasn't been prepended to yet keeps the refined methods in the module's method table. When prepending, the module's method table is moved to the origin iclass, and then the refined methods are moved from the method table to a new method table in the module itself. Unfortunately, that means that if a class has included the module, prepending breaks the refinements, because when the methods are moved from the origin iclass method table to the module method table, they are removed from the method table from the iclass created when the module was included earlier. Fix this by always creating an origin class when including a module that has any refinements, even if the refinements are not currently used. I wasn't sure the best way to do that. The approach I choose was to use an object flag. The flag is set on the module when Module#refine is called, and if the flag is present when the module is included in another module or class, an origin iclass is created for the module. Fixes [Bug #13446]
* Warn on access/modify of $SAFE, and remove effects of modifying $SAFEJeremy Evans2019-11-181-1/+0
| | | | | | | | | | | | | | | | | This removes the security features added by $SAFE = 1, and warns for access or modification of $SAFE from Ruby-level, as well as warning when calling all public C functions related to $SAFE. This modifies some internal functions that took a safe level argument to no longer take the argument. rb_require_safe now warns, rb_require_string has been added as a version that takes a VALUE and does not warn. One public C function that still takes a safe level argument and that this doesn't warn for is rb_eval_cmd. We may want to consider adding an alternative method that does not take a safe level argument, and warn for rb_eval_cmd.

* Only set RB_PASS_CALLED_KEYWORDS in C functions called directly from RubyJeremy Evans2019-09-141-1/+8
| | | | | | | | | | | It is not safe to set this in C functions that can be called from other C functions, as in the non argument-delegation case, you can end up calling a Ruby method with a flag indicating keywords are set without passing keywords. Introduce some new *_kw functions that take a kw_splat flag and use these functions to set RB_PASS_CALLED_KEYWORDS in places where we know we are delegating methods (e.g. Class#new, Method#call)
* Consolidate empty keyword handlingJeremy Evans2019-09-131-14/+1
| | | | | | | | | | | | | | | | | | | | | | Remove rb_add_empty_keyword, and instead of calling that every place you need to add empty keyword hashes, run that code in a single static function in vm_eval.c. Add 4 defines to include/ruby/ruby.h, these are to be used as int kw_splat values when calling the various rb_*_kw functions: RB_NO_KEYWORDS :: Do not pass keywords RB_PASS_KEYWORDS :: Pass final argument (which should be hash) as keywords RB_PASS_EMPTY_KEYWORDS :: Add an empty hash to arguments and pass as keywords RB_PASS_CALLED_KEYWORDS :: Passes same keyword type as current method was called with (for method delegation) rb_empty_keyword_given_p needs to stay. It is required if argument delegation is done but delayed to a later point, which Enumerator does. Use RB_PASS_CALLED_KEYWORDS in rb_call_super to correctly delegate keyword arguments to super method.
* Convert keyword argument to required positional hash argument for Class#new, ↵Jeremy Evans2019-09-061-1/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Method#call, UnboundMethod#bind_call Also add keyword argument separation warnings for Class#new and Method#call. To allow for keyword argument to required positional hash converstion in cfuncs, add a vm frame flag indicating the cfunc was called with an empty keyword hash (which was removed before calling the cfunc). The cfunc can check this frame flag and add back an empty hash if it is passing its arguments to another Ruby method. Add rb_empty_keyword_given_p function for checking if called with an empty keyword hash, and rb_add_empty_keyword for adding back an empty hash to argv. All of this empty keyword argument support is only for 2.7. It will be removed in 3.0 as Ruby 3 will not convert empty keyword arguments to required positional hash arguments. Comment all of the relevent code to make it obvious this is expected to be removed. Add rb_funcallv_kw as an public C-API function, just like rb_funcallv but with a keyword flag. This is used by rb_obj_call_init (internals of Class#new). This also required expected call_type enum with CALL_FCALL_KW, similar to the recent addition of CALL_PUBLIC_KW. Add rb_vm_call_kw as a internal function, used by call_method_data (internals of Method#call and UnboundMethod#bind_call). Add tests for UnboundMethod#bind_call keyword handling.

* add include/ruby/backward/cxxanyargs.hpp卜部昌平2019-09-061-3/+15
| | | | | | | | | | | | | | Compilation of extension libraries written in C++ are reportedly broken due to https://github.com/ruby/ruby/pull/2404 The root cause of this issue was that the definition of ANYARGS differ between C and C++, and that of C++ is incompatible with the updated ones. We are using the incompatibility against itself. In C++ two distinct function prototypes can be overloaded. We provide the old, ANYARGSed prototypes in addition to the current granular ones; and let the older ones warn about types.
