All `raw' + hooks are kicked under protection (same as normal hooks). + + * include/ruby/ruby.h: remove internal data definition and + macros. + + * internal.h (ruby_suppress_tracing), vm_trace.c: rename + ruby_suppress_tracing() to rb_suppress_tracing() + and remove unused function parameter. + + * parse.y: fix to use renamed rb_suppress_tracing(). + + * thread.c (thread_create_core): no need to set RUBY_VM_VM. + + * vm.c (mark_event_hooks): move definition to vm_trace.c. + + * vm.c (ruby_vm_event_flags): add a global variable. + This global variable represents all of Threads and VM's + event masks (T1#events | T2#events | ... | VM#events). + You can check the possibility kick trace func or not + with ruby_vm_event_flags. + ruby_vm_event_flags is maintained by vm_trace.c. + + * cont.c (fiber_switch, rb_cont_call): restore tracing status. + [Feature #4347] + + * test/ruby/test_continuation.rb: ditto. + Thu Aug 16 19:15:23 2012 Nobuyoshi Nakada <nobu@ruby-lang.org> * object.c (rb_class_initialize): forbid inheriting uninitialized |
