* push dummy frame for loading processKoichi Sasada2022-10-201-6/+14
| | | | | | | | | | | | | This patch pushes dummy frames when loading code for the profiling purpose. The following methods push a dummy frame: * `Kernel#require` * `Kernel#load` * `RubyVM::InstructionSequence.compile_file` * `RubyVM::InstructionSequence.load_from_binary` https://bugs.ruby-lang.org/issues/18559

* Prevent printing crash report in a loopAlan Wu2022-06-031-0/+11
| | | | | | | | | | | In the event that we are crashing due to a corrupt Ruby stack, we might re-enter rb_vm_bugreport() due to failed assertions in rb_backtrace_print_as_bugreport() or SDR(). In these cases we were printing the bug report ad infinitum with unbounded recusion. I seem to run into this every once in a while and the amount of log it prints out is pretty distracting. On CI environments it makes the log output unnecessarily big. Let's fix this.
* remove `NON_SCALAR_THREAD_ID` supportKoichi Sasada2022-05-241-7/+1
| | | | | | | | | `NON_SCALAR_THREAD_ID` shows `pthread_t` is non-scalar (non-pointer) and only s390x is known platform. However, the supporting code is very complex and it is only used for deubg print information. So this patch removes the support of `NON_SCALAR_THREAD_ID` and make the code simple.
* introduce struct `rb_native_thread`Koichi Sasada2022-04-231-2/+2
| | | | | | | | | `rb_thread_t` contained `native_thread_data_t` to represent thread implementation dependent data. This patch separates them and rename it `rb_native_thread` and point it from `rb_thraed_t`. Now, 1 Ruby thread (`rb_thread_t`) has 1 native thread (`rb_native_thread`).

* Add ISEQ_BODY macroPeter Zhu2022-03-241-12/+12
| | | | | | Use ISEQ_BODY macro to get the rb_iseq_constant_body of the ISeq. Using this macro will make it easier for us to change the allocation strategy of rb_iseq_constant_body when using Variable Width Allocation.

* Crash more nicely when the VM isn't fully set upAaron Patterson2021-06-101-30/+32
| | | | If we crash but the VM isn't fully alive, we can get an infinite loop.
* Don't create objects during GCAaron Patterson2021-06-071-1/+1
| | | | | | 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
* Do not expect ec on rb_vm_bugreportTakashi Kokubun2021-06-021-1/+1
| | | | | 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.
* vm_dump.c: rename HAVE_BACKTRACE to USE_BACKTRACEBenoit Daloze2021-05-041-7/+8

| | | | | | This reverts commit 6985bfb72c8d7e7d94f1aad1f0902b602bbfa6da. Now it should work on riscv by the previous commit. [Bug #17609]

* Allow an MJIT worker to show a backtrace on SEGVTakashi Kokubun2020-12-101-1/+2
| | | | | 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.

* fix public interfaceKoichi Sasada2020-11-181-1/+1
| | | | | | | | | | | | | | | | | | To make some kind of Ractor related extensions, some functions should be exposed. * include/ruby/thread_native.h * rb_native_mutex_* * rb_native_cond_* * include/ruby/ractor.h * RB_OBJ_SHAREABLE_P(obj) * rb_ractor_shareable_p(obj) * rb_ractor_std*() * rb_cRactor and rm ractor_pub.h and rename srcdir/ractor.h to srcdir/ractor_core.h (to avoid conflict with include/ruby/ractor.h)
* Introduce Ractor mechanism for parallel executionKoichi Sasada2020-09-031-3/+5
| | | | | | | | | | | | | | | | 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.

* vm_dump.c: Do not show C backtrace on riscvYusuke Endoh2020-04-201-1/+1
| | | | | Currently, objdump -W miniruby emits some errors on riscv, so I guess that DWARF is corrupted.
* Removed useless VMDEBUG definition [ci skip]Nobuyoshi Nakada2020-04-191-6/+0
| | | | VMDEBUG is always defined as defaulted to 0 in vm_core.h.
* Update VMDEBUG reference doc [ci skip]Nguyễn Quang Minh2020-04-191-1/+1
| | | 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.

* Introduce disposable call-cache.Koichi Sasada2020-02-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* support RUBY_ON_BUG envval on assert failure.Koichi Sasada2020-01-061-0/+12

* decouple internal.h headers卜部昌平2019-12-261-15/+20
| | | | | | | | | | | | | | | | | | 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).

* add additional CF info for CI envKoichi Sasada2019-12-051-7/+43
| | | | | | | | | Introduce new RUBY_DEBUG option 'ci' to inform Ruby interpreter that an interpreter is running on CI environment. With this option, `rb_bug()` shows more information includes method entry information, local variables information for each control frame.
