2021-06-10Crash more nicely when the VM isn't fully set upAaron Patterson
If we crash but the VM isn't fully alive, we can get an infinite loop.
2021-06-07Don't create objects during GCAaron Patterson
If we crash during GC, allocating new objects in the segv handler can cause an infinite loop. This commit is to avoid creating new objects in the crash handler
2021-06-02Do not expect ec on rb_vm_bugreportTakashi Kokubun
because a SEGV might happen on an MJIT worker. As you can clearly see from `if (vm && ec) {`, ec is not guaranteed to exist here.

2020-12-10Allow an MJIT worker to show a backtrace on SEGVTakashi Kokubun
An MJIT worker thread doesn't have ec, and it's required for SDR() and rb_backtrace_print_as_bugreport(). Therefore it must be checked.

2020-09-03Introduce Ractor mechanism for parallel executionKoichi Sasada
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. Notes: Merged: https://github.com/ruby/ruby/pull/3365

Currently, objdump -W miniruby emits some errors on riscv, so I guess that DWARF is corrupted.
2020-04-19Removed useless VMDEBUG definition [ci skip]Nobuyoshi Nakada
VMDEBUG is always defined as defaulted to 0 in vm_core.h.
2020-04-19Update VMDEBUG reference doc [ci skip]Nguyễn Quang Minh
Since this commit (https://github.com/ruby/ruby/commit/9e1b06e17d27fb4ddf51e9244f205417e9c4dd5c), the VM Debug Level constant is moved from `vm_insnhelper.h` to `vm_core.h`. This PR is a super tiny update to reflect that change so that people won't waste time on searching in a wrong file.

2020-02-22Introduce disposable call-cache.Koichi Sasada
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. Notes: Merged: https://github.com/ruby/ruby/pull/2888

2019-12-27Get rid of LIST_HEAD conflict with a system header on macOSNobuyoshi Nakada
2019-12-26decouple internal.h headers卜部昌平
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). Notes: Merged: https://github.com/ruby/ruby/pull/2711

2017-10-26Use rb_execution_context_t instead of rb_thread_tko1
to represent execution context [Feature #14038] * vm_core.h (rb_thread_t): rb_thread_t::ec is now a pointer. There are many code using `th` to represent execution context (such as cfp, VM stack and so on). To access `ec`, they need to use `th->ec->...` (adding one indirection) so that we need to replace them by passing `ec` instead of `th`. * vm_core.h (GET_EC()): introduced to access current ec. Also remove `ruby_current_thread` global variable. * cont.c (rb_context_t): introduce rb_context_t::thread_ptr instead of rb_context_t::thread_value. * cont.c (ec_set_vm_stack): added to update vm_stack explicitly. * cont.c (ec_switch): added to switch ec explicitly. * cont.c (rb_fiber_close): added to terminate fibers explicitly. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@60440 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
