2018-11-06cont.c: direct use of rb_thread_tshyouhei
The only usage of rb_fiber_reset_root_local_storage() is from ruby_vm_destruct(), where the object space is already terminated. This `th->self` is not alive. Why not just use `th` itself. See also: git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-09-12fiber: fix crash on GC after forkingnormal
Remove the remainder of ROOT_FIBER_CONTEXT use and unnecessary differences between the root and non-root fiber. This makes it easier to follow new root fiber at fork time. Multiple sources of truth often leads to bugs, as in this case. We can determinte root fiber by checking a fiber against the root_fiber of its owner thread. The new `fiber_is_root_p' function supports that. Now, we can care only about free-ing/recycling/munmap-ing stacks as appropriate.

2018-09-12cont.c (fiber_memsize): do not rely on ROOT_FIBER_CONTEXTnormal
We can check if the fiber we're interested in is the th->root_fiber for the owner thread, so there is no need to use ROOT_FIBER_CONTEXT. Note: there is no guarantee th->ec points to &th->root_fiber->cont.saved_ec, thus vm::thread_memsize may not account for root fiber correctly (pre-existing bug).

ec->vm_stack is always allocated with malloc, so stack cache for root fiber (thread stack) and non-root fibers can be shared as long as the size is the same.

2018-07-26cont.c (ec_switch): prevent delayed/missed trap interrupt racenormal
timer-thread may set trap interrupt with rb_threadptr_check_signal at any time independent of GVL. This means timer-thread may set the trap interrupt flag on the previous execution context; causing the flag to be unnoticed until a future ec switch (or lost completely if the ec is done). Note: I avoid relying on th->interrupt_lock here and use atomics because we won't be able to rely on it for proposed lazy timer-thread [Misc #14937]. This regression affects Ruby 2.5 as it was introduced by moving interrupt_flag to `ec' which is an unstable pointer. Ruby <= 2.4 was unaffected because vm->main_thread->interrupt_flag never changed.

Fiber objects wrapping this rb_fiber_t for root_fiber are created when root Fiber object is required explicitly (for example, Fiber switching and so on). We can put calling `ConvertThreadToFiber()`.

This means that root_fib->fib_handle of child thread is initialized with parent thread's Fiber handle. Furthermore, second call of `ConvertThreadToFiber()` for the same thread fails.

However, maybe we can make more clean code. * thread.c (thread_start_func_2): call `rb_threadptr_root_fiber_setup_by_child()` at thread initialize routine. * vm.c (th_init): call `rb_threadptr_root_fiber_setup_by_parent()`. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
2018-02-04mjit.c: merge MJIT infrastructurek0kubun
that allows to JIT-compile Ruby methods by generating C code and using C compiler. See the first comment of mjit.c to know what this file does. mjit.c is authored by Vladimir Makarov <>. After he invented great method JIT infrastructure for MRI as MJIT, Lars Kanis <> sent the patch to support MinGW in MJIT. In addition to merging it, I ported pthread to Windows native threads. Now this MJIT infrastructure can be compiled on Visual Studio. This commit simplifies mjit.c to decrease code at initial merge. For example, this commit does not provide multiple JIT threads support. We can resurrect them later if we really want them, but I wanted to minimize diff to make it easier to review this patch. `/tmp/_mjitXXX` file is renamed to `/tmp/_ruby_mjitXXX` because non-Ruby developers may not know the name "mjit" and the file name should make sure it's from Ruby and not from some harmful programs. TODO: it may be better to store this to some temporary directory which Ruby is already using by Tempfile, if it's not bad for performance. mjit.h: New. It has `mjit_exec` interface similar to `vm_exec`, which is for triggering MJIT. This drops interface for AOT compared to the original MJIT. define macros to let MJIT know the path of MJIT header. Probably we can refactor this to reduce the number of macros (TODO). win32/Makefile.sub: ditto. compile mjit.o and mjit_compile.o. Unlike original MJIT, this commit separates MJIT infrastructure and JIT compiler code as independent object files. As initial patch is NOT going to have ultra-fast JIT compiler, it's likely to replace JIT compiler, e.g. original MJIT's compiler or some future JIT impelementations which are not public now. inits.c: define MJIT module. This is added because `MJIT.enabled?` was necessary for testing. test/lib/zombie_hunter.rb: skip if `MJIT.enabled?`. Obviously this wouldn't work with current code when JIT is enabled. test/ruby/test_io.rb: skip this too. This would make no sense with MJIT. ruby.c: define MJIT CLI options. As major difference from original MJIT, "-j:l"/"--jit:llvm" are renamed to "--jit-cc" because I want to support not only gcc/clang but also cl.exe (Visual Studio) in the future. But it takes only "--jit-cc=gcc", "--jit-cc=clang" for now. And only long "--jit" options are allowed since some Ruby committers preferred it at Ruby developers Meeting on January, and some of options are renamed. This file also triggers to initialize MJIT thread and variables. eval.c: finalize MJIT worker thread and variables. test/ruby/test_rubyoptions.rb: fix number of CLI options for --jit. thread_pthread.c: change for pthread abstraction in MJIT. Prefix rb_ for functions which are used by other files. thread_win32.c: ditto, for Windows. Those pthread porting is one of major works that YARV-MJIT created, which is my fork of MJIT, in Feature 14235. thread.c: follow rb_ prefix changes vm.c: trigger MJIT call on VM invocation. Also trigger `mjit_mark` to avoid SEGV by race between JIT and GC of ISeq. The improvement was provided by wanabe <>. In JIT compiler I created and am going to add in my next commit, I found that having `mjit_exec` after `vm_loop_start:` is harmful because the JIT-ed function doesn't proceed other ISeqs on RESTORE_REGS of leave insn. Executing non-FINISH frame is unexpected for my JIT compiler and `exception_handler` triggers executions of such ISeqs. So `mjit_exec` here should be executed only when it directly comes from `vm_exec` call. `RubyVM::MJIT` module and `.enabled?` method is added so that we can skip some tests which don't expect JIT threads or compiler file descriptors. vm_insnhelper.h: trigger MJIT on method calls during VM execution. vm_core.h: add fields required for mjit.c. `bp` must be `cfp[6]` because rb_control_frame_struct is likely to be casted to another struct. The last position is the safest place to add the new field. vm_insnhelper.c: save initial value of cfp->ep as cfp->bp. This is an optimization which are done in both MJIT and YARV-MJIT. So this change is added in this commit. Calculating bp from ep is a little heavy work, so bp is kind of cache for it. iseq.c: notify ISeq GC to MJIT. We should know which iseq in MJIT queue is GCed to avoid SEGV. TODO: unload some GCed units in some safe way. gc.c: add hooks so that MJIT can wait GC, and vice versa. Simultaneous JIT and GC executions may cause SEGV and so we should synchronize them. cont.c: save continuation information in MJIT worker. As MJIT shouldn't unload JIT-ed code which is being used, MJIT wants to know full list of saved execution contexts for continuation and detect ISeqs in use. mjit_compile.c: added empty JIT compiler so that you can reuse this commit to build your own JIT compiler. This commit tries to compile ISeqs but all of them are considered as not supported in this commit. So you can't use JIT compiler in this commit yet while we added --jit option now.

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:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2017-09-10store ec instead of thread in rb_context_t.ko1
* cont.c (rb_context_t): introduce saved_ec instaad of saved_thread. We only need to transfer ec data (not all of thread data). Introduce `thread_value` field to point creation thread. To acccess this field, `cont_thread_value()` is introduced. * vm.c (rb_execution_context_mark): remove `static` and use it from cont.c (use this function instead of `rb_thread_mark`). * vm_insnhelper.c (rb_vm_push_frame): accept ec instead of th. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
