* YJIT: GC and recompile all code pages (#6406)Takashi Kokubun2022-10-251-1/+1
| | | | | when it fails to allocate a new page. Co-authored-by: Alan Wu <alansi.xingwu@shopify.com>
* MJIT: Stop using the VM barrier for jit_contTakashi Kokubun2022-10-191-13/+22
| | | | | | | | | | | | | | | | This solves multiple problems. First, RB_VM_LOCK_ENTER/LEAVE is a barrier. We could at least use the _NO_BARRIER variant. Second, this doesn't need to interfere with GC or other GVL users when multiple Ractors are used. This needs to be used in very few places, so the benefit of fine-grained locking would outweigh its small maintenance cost. Third, it fixes a crash for YJIT. Because YJIT is never disabled until a process exits unlike MJIT that finishes earlier, we could call jit_cont_free when EC no longer exists, which crashes RB_VM_LOCK_ENTER.

* Rename rb_ary_tmp_new to rb_ary_hidden_newPeter Zhu2022-07-261-1/+1
| | | | | | rb_ary_tmp_new suggests that the array is temporary in some way, but that's not true, it just creates an array that's hidden and not on the transient heap. This commit renames it to rb_ary_hidden_new.
* Prevent the stack from being marked twiceAaron Patterson2022-07-201-0/+6
| | | | | | | This commit prevents the stack from being marked twice: once via the Fiber, and once via the Thread. It introduces an assertion to assert that the ec on the thread is the same as the ec on the Fiber being marked via the thread.
* cont.c: prevent a warning of GCC 12.1Yusuke Endoh2022-06-131-0/+4
| | | | | | | | | | | | | | ... 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.

* Add ISEQ_BODY macroPeter Zhu2022-03-241-1/+1
| | | | | | 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.
* Fix potential memory leak at fiber poolNobuyoshi Nakada2022-03-181-2/+2
| | | | | Do not "allocate then wrap". It leaks the allocated memory if failed to create the wrapper.

* Fix experimental Fiber::Pool definitionNobuyoshi Nakada2022-03-131-1/+1
| | | | | Toplevel `Pool` is too generic, and `struct fiber_pool` does not seem compatible with `rb_fiber_t`.
* `rb_fiber_terminate` must not return [Bug #18497]Nobuyoshi Nakada2022-01-191-1/+2
| | | | | | | | 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.

* Fix conflicting declaration on SolarisNobuyoshi Nakada2021-11-301-2/+1
| | | | | | | | | | | | | | | | | | | | SunC ``` "cont.c", line 24: identifier redeclared: madvise current : function(pointer to char, unsigned int, int) returning int previous: function(pointer to void, unsigned int, int) returning int : "/usr/include/sys/mman.h", line 232 ``` GCC ``` cont.c:24:12: error: conflicting types for 'madvise' 24 | extern int madvise(caddr_t, size_t, int); | ^~~~~~~ In file included from cont.c:16: /usr/include/sys/mman.h:232:12: note: previous declaration of 'madvise' was here 232 | extern int madvise(void *, size_t, int); | ^~~~~~~ ```
* Workaround for implicit declaration of function 'madvise' on SolarisNaohisa Goto2021-11-301-0/+8
| | | | | | | | 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.
* rb_fiber_raise(): add doxygen卜部昌平2021-09-301-2/+2
| | | | Must not be a bad idea to improve documents.
* Expose `rb_fiber_raise` and tidy up the internal implementation.Samuel Williams2021-09-201-71/+94
