* RDoc does not seem to support documenting singleton object methods, and making $LOAD_PATH a class as a workaround is too weird.
2019-07-11$LOAD_PATH.resolve_feature_pathNobuyoshi Nakada
Moved from RubyVM. [Feature #15903]
2019-06-20Ensure that vm_stack is cleared in `thread_cleanup_func_before_exec`.Samuel Williams
If `vm_stack` is left dangling in a forked process, the gc attempts to scan it, but it is invalid and will cause a segfault. Therefore, we clear it before forking. In order to simplify this, `rb_ec_clear_vm_stack` was introduced.
2019-06-20Revert failed attempt at fixing invalid usage of vm_stack.Samuel Williams

2019-06-11Add compaction support for more types.Aaron Patterson
This commit adds compaction support for: * Fibers * Continuations * Autoload Constants
2019-06-01Make opt_aref instruction support Integer#[]Yusuke Endoh
only when its receiver and the argument are both Integers. Since 6bedbf4625, Integer#[] has supported a range extraction. This means that Integer#[] now accepts multiple arguments, which made the method very slow unfortunately. This change fixes the performance issue by adding a special handling for its traditional use case: `num[idx]` where both `num` and `idx` are Integers.
2019-05-31Use UNALIGNED_MEMBER_PTRNobuyoshi Nakada
* internal.h (UNALIGNED_MEMBER_ACCESS, UNALIGNED_MEMBER_PTR): moved from eval_intern.h. * compile.c iseq.c, vm.c: use UNALIGNED_MEMBER_PTR for `entries` in `struct iseq_catch_table`. * vm_eval.c, vm_insnhelper.c: use UNALIGNED_MEMBER_PTR for `body` in `rb_method_definition_t`.
2019-05-31Keep vm->orig_progname aliveAlan Wu
`vm->orig_progname` can be different from `vm->progname` when user code assigns to `$0`. While `vm->progname` is kept alive by the global table, nothing marked `vm->orig_progname`. [Bug #15887]
2019-05-22Eagerly name modules and classesAlan Wu
* variable.c: make the hidden ivars `classpath` and `tmp_classpath` the source of truth for module and constant names. Assign to them when modules are bind to constants. * variable.c: remove references to module name cache, as what used to be the cache is now the source of truth. Remove rb_class_path_no_cache(). * variable.c: remove the hidden ivar `classid`. This existed for the purposes of module name search, which is now replaced. Also, remove the associated rb_name_class(). * class.c: use rb_set_class_path_string to set the name of Object during boot. Must use a fstring as this runs before rb_cString is initialized and creating a normal string leads to a VALUE without a class. * spec/ruby/core/module/name_spec.rb: add a few specs to specify what happens to Module#name across multiple operations. These specs pass without other code changes in this commit. [Feature #15765]
2019-05-14Fixing function nameAaron Patterson
This function is used for marking / pinning vm stack values, so it should have "vm" in the function name to be more clear.
2019-04-22Prevent rb_define_(class|module) classes from movingAaron Patterson
Before this commit, classes and modules would be registered with the VM's `defined_module_hash`. The key was the ID of the class, but that meant that it was possible for hash collisions to occur. The compactor doesn't allow classes in the `defined_module_hash` to move, but if there is a conflict, then it's possible a class would be removed from the hash and not get pined. This commit changes the key / value of the hash just to be the class itself, thus preventing movement.

2019-04-05add definemethod/definesmethod insn.ko1
* insns.def: add definemethod and definesmethod (singleton method) instructions. Old YARV contains these instructions, but it is moved to methods of FrozenCore class because remove number of instructions can improve performance for some techniques (static stack caching and so on). However, we don't employ these technique and it is hard to optimize/analysis definition sequence. So I decide to introduce them (and remove definition methods). `putiseq` insn is also removed. * vm_method.c (rb_scope_visibility_get): renamed to `vm_scope_visibility_get()` and make it accept `ec`. Same for `vm_scope_module_func_check()`. These fixes are result of refactoring `vm_define_method`. * vm_insnhelper.c (rb_vm_get_cref): renamed to `vm_get_cref` because of consistency with other functions. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@67442 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-12-26insns.def: refactor to avoid CALL_METHOD macroshyouhei
These send and its variant instructions are the most frequently called paths in the entire process. Reducing macro expansions to make them dedicated function called vm_sendish() is the main goal of this changeset. It reduces the size of vm_exec_coref from 25,552 bytes to 23,728 bytes on my machine. I see no significant slowdown.

2018-12-24remove "deprecated" for rb_frame_method_id_and_class [Bug #15300]ko1
* include/ruby/backward.h (rb_frame_method_id_and_class): we had labeled `rb_frame_method_id_and_class()` as deprecated because MRI internal doesn't use it, but we found there are user of this API in external C-extensions. Now we don't have proper alternative API and no time to make alternative API, so I remove "deprecated" label.

2018-12-06Return same ISeq object for one src.ko1
* iseq.c: before this patch, RubyVM::InstructionSequence.of(src) (ISeq in short) returns different ISeq (wrapper) objects point to one ISeq internal object. This patch changes this behavior to cache created ISeq (wrapper) objects and return same ISeq object for an internal ISeq object. * iseq.h (ISEQ_EXECUTABLE_P): introduced to check executable ISeq objects. * iseq.h (ISEQ_COMPILE_DATA_ALLOC): reordr setting flag line to avoid ISEQ_USE_COMPILE_DATA but compiled_data == NULL case. * vm_core.h (rb_iseq_t): introduce `rb_iseq_t::wrapper` and `rb_iseq_t::aux::exec`. Move `rb_iseq_t::local_hooks` to `rb_iseq_t::aux::exec::local_hooks`. * test/ruby/test_iseq.rb: add ISeq.of() tests. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66246 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2018-11-26Support targetting TracePoint [Feature #15289]ko1
* vm_trace.c (rb_tracepoint_enable_for_target): support targetting TracePoint. [Feature #15289] Tragetting TracePoint is only enabled on specified method, proc and so on, example: `tp.enable(target: code)`. `code` should be consisted of InstructionSeuqnece (iseq) (RubyVM::InstructionSeuqnece.of(code) should not return nil) If code is a tree of iseq, TracePoint is enabled on all of iseqs in a tree. Enabled tragetting TracePoints can not enabled again with and without target. * vm_core.h (rb_iseq_t): introduce `rb_iseq_t::local_hooks` to store local hooks. `rb_iseq_t::aux::trace_events` is renamed to `global_trace_events` to contrast with `local_hooks`. * vm_core.h (rb_hook_list_t): add `rb_hook_list_t::running` to represent how many Threads/Fibers are used this list. If this field is 0, nobody using this hooks and we can delete it. This is why we can remove code from cont.c. * vm_core.h (rb_vm_t): because of above change, we can eliminate `rb_vm_t::trace_running` field. Also renamed from `rb_vm_t::event_hooks` to `global_hooks`. * vm_core.h, vm.c (ruby_vm_event_enabled_global_flags): renamed from `ruby_vm_event_enabled_flags. * vm_core.h, vm.c (ruby_vm_event_local_num): added to count enabled targetting TracePoints. * vm_core.h, vm_trace.c (rb_exec_event_hooks): accepts hook list. * vm_core.h (rb_vm_global_hooks): added for convinience. * method.h (rb_method_bmethod_t): added to maintain Proc and `rb_hook_list_t` for bmethod (defined by define_method). * prelude.rb (TracePoint#enable): extracet a keyword parameter (because it is easy than writing in C). It calls `TracePoint#__enable` internal method written in C. * vm_insnhelper.c (vm_trace): check also iseq->local_hooks. * vm.c (invoke_bmethod): check def->body.bmethod.hooks. * vm.c (hook_before_rewind): check iseq->local_hooks and def->body.bmethod.hooks before rewind by exception. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@66003 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
