2022-06-13cont.c: prevent a warning of GCC 12.1Yusuke Endoh
... by assigning a dummy value to the allocated stack. http://rubyci.s3.amazonaws.com/arch/ruby-master/log/20220613T000004Z.log.html.gz ``` cont.c: In function ‘cont_restore_0.constprop’: cont.c:1489:28: warning: ‘*sp’ may be used uninitialized [-Wmaybe-uninitialized] 1489 | space[0] = *sp; | ^~~ ``` Also it adds some comments about the hack of dummy stack allocation.

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. Notes: Merged: https://github.com/ruby/ruby/pull/5698

2022-01-19`rb_fiber_terminate` must not return [Bug #18497]Nobuyoshi Nakada
In a forked process from a fiber, the fiber becomes the only fiber, `fiber_switch` does nothing as there is no other fibers, `rb_fiber_terminate` does not terminate the fiber. In that case, reaches the end of `fiber_entry` finaly, which is declared as "COROUTINE" and should never return. Notes: Merged: https://github.com/ruby/ruby/pull/5468

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>
2021-02-09Expose scheduler as public interface & bug fixes. (#3945)Samuel Williams
* Rename `rb_scheduler` to `rb_fiber_scheduler`. * Use public interface if available. * Use `rb_check_funcall` where possible. * Don't use `unblock` unless the fiber was non-blocking. Notes: Merged-By: ioquatix <samuel@codeotaku.com>
