* cont.c (rb_fiber_reset_root_local_storage): add a new function to restore rb_thread_t::local_storage. * cont.c (rb_obj_is_fiber): add a new function to tell finalizer to prevent fibers from destroy. * gc.c (rb_objspace_call_finalizer): don't sweep fibers at finalizing objspace. * internal.h (rb_fiber_reset_root_local_storage, rb_obj_is_fiber): add prototypes. * vm.c (ruby_vm_destruct): reset main thread's local_storage before free main thread. rb_thread_t::local_storage is replaced by fiber's local storage when forked from fiber, and it should be already freed when the fiber was destroyed. * test/ruby/test_fiber.rb (test_fork_from_fiber): add test for fork from fiber. when the fiber was destroyed.

* cont.c (cont_restore_0): prevent optimizing out `sp'. sp is used for reserving a memory space with ALLOCA_N for restoring machine stack stored in cont->machine_stack, but clang optimized out it (and maybe #5851 is also caused by this). This affected TestContinuation#test_check_localvars. * cont.c (cont_restore_1): revert workaround introduced in r32201. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_1_9_3@34288 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

2010-05-05* vm_method.c (rb_unlink_method_entry, rb_sweep_method_entry):ko1
added. Unlinked method entries are collected to vm->unlinked_method_entry_list. On the GC timing, mark all method entries which are on all living threads. Only non-marked method entries are collected. This hack prevents releasing living method entry. [Performance Consideration] Since this Method Entry GC (MEGC) doesn't occuer frequently, MEGC will not be a performance bottleneck. However, to traverse living method entries, every control frame push needs to clear cfp->me field. This will be a performance issue (because pushing control frame is occurred frequently). Bug #2777 [ruby-dev:40457] * cont.c (fiber_init): init cfp->me. * gc.c (garbage_collect): kick rb_sweep_method_entry(). * method.h (rb_method_entry_t): add a mark field. * vm.c (invoke_block_from_c): set passed me. * vm.c (rb_thread_mark): mark cfp->me. * vm_core.h (rb_thread_t): add a field passed_me. * vm_core.h (rb_vm_t): add a field unlinked_method_entry_list. * vm_insnhelper.c (vm_push_frame): clear cfp->me at all times. * vm_insnhelper.c (vm_call_bmethod): pass me. * bootstraptest/test_method.rb: add a test. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@27634 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
