2021-11-30Workaround for implicit declaration of function 'madvise' on SolarisNaohisa Goto
On Solaris, madvise(3C) is NOT defined for SUS (XPG4v2) or later, but MADV_* macros are defined when __EXTENSIONS__ is defined. This may cause compile error on Solaris 10 with GCC when "-Werror=implicit-function-declaration" and "-D_XOPEN_SOURCE=600" are added by configure.

2021-02-24rb_fiber_terminate never returnsNobuyoshi Nakada
2021-02-22Send :fiber_switch event for almost every fiber_switch (#4207)nicholas a. evans
With this patch, TracePoint receives a `:fiber_switch` event for _almost_ every fiber switch. Previously, it would not be sent when an exception was going to be raised. Now the event should only be blockable by an interrupt (including `Thread#raise`) or a fatal error. Additionally, interrupts will now be checked on the return fiber _before_ re-raising the terminating unhandled exception. And a fiber that terminates with an unhandled exception no longer creates a pending interrupt on its thread. The exception will be raised in the return fiber the same way as `Fiber#raise`: using `cont.value` with `cont.argc == -1` I moved `rb_exc_raise` from `fiber_store` to the end of `fiber_switch` after _all_ of the other cleanup code: `fiber_stack_release`, `th->blocking` increment, `RUBY_VM_CHECK_INTS`, and `EXEC_EVENT_HOOK`. It seems to me that skipping those other cleanup steps may have also resulted in other bugs. Notes: Merged-By: ioquatix <samuel@codeotaku.com>

:bow:
2020-11-21Make sure all threads are scanned on unload_unitsTakashi Kokubun
This has been a TODO since 79df14c04b. While adcf0316d1 covered the root_fiber of the initial thread, it didn't cover root_fibers of other threads. Now it's hooked properly in rb_threadptr_root_fiber_setup. With regards to "XXX: Is this mjit_cont `mjit_cont_free`d?", when rb_threadptr_root_fiber_release is called, although I'm not sure when th->root_fiber is truthy, fiber_free seems to call cont_free and mjit_cont_free. So mjit_conts of root_fibers seem to be freed properly.

2020-10-12relax Fiber#transfer's restrictionKoichi Sasada
Using Fiber#transfer with Fiber#resume for a same Fiber is limited (once Fiber#transfer is called for a fiber, the fiber can not be resumed more). This restriction was introduced to protect the resume/yield chain, but we realized that it is too much to protect the chain. Instead of the current restriction, we introduce some other protections. (1) can not transfer to the resuming fiber. (2) can not transfer to the yielding fiber. (3) can not resume transferred fiber. (4) can not yield from not-resumed fiber. [Bug #17221] Also at the end of a transferred fiber, it had continued on root fiber. However, if the root fiber resumed a fiber (and that fiber can resumed another fiber), this behavior also breaks the resume/yield chain. So at the end of a transferred fiber, switch to the edge of resume chain from root fiber. For example, root fiber resumed f1 and f1 resumed f2, transferred to f3 and f3 terminated, then continue from the fiber f2 (it was continued from root fiber without this patch).

2020-10-01Fix a use-after-free bug reported by ASANAaron Patterson
If a fiber and thread are collected at the same time, the thread might get collected first and the pointer on the fiber will go bad. I don't think we need to check whether or not this is the main fiber in order to release its stack Notes: Merged: https://github.com/ruby/ruby/pull/3571
2020-09-14Make Mutex per-Fiber instead of per-ThreadBenoit Daloze

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
