nobu 628f75b752 vm_core.h: rb_thread_struct::machine
* vm_core.h (rb_thread_struct): aggregate cpu stuff into a struct,
  so that a debugger can show its content at once.

tarui 28a1c4f33e * cont.c : Introdule ensure rollback mechanism. Please see below.
* internal.h (ruby_register_rollback_func_for_ensure): catch up above change.
	  Add rollback mechanism API.

	* vm_core.h (typedef struct rb_vm_struct): catch up above change.
	  Introdule ensure-rollback relation table.

	* vm_core.h (typedef struct rb_thread_struct): catch up above change.
	  Introdule ensure stack.

	* eval.c (rb_ensure): catch up above change.
	  Introdule ensure stack.

	* hash.c : New function for rollback ensure, and register it to
	  ensure-rollback relation table. [ruby-dev:47803] [Bug #9105]

	Ensure Rollback Mechanism:
	A rollback's function is a function to rollback a state before ensure's
	function execution.
	When the jump of callcc is across the scope of rb_ensure,
	ensure's functions and rollback's functions are executed appropriately
	for keeping consistency.

	Current API is unstable, and only internal use.

	ruby_register_rollback_func_for_ensure(ensure_func,rollback_func)
	This API create relation ensure's function to rollback's function.
	By registered rollback's function, it is executed When jumpping into
	corresponding rb_ensure scope.

ko1 d1674ef67b * gc.c: add support to estimate increase of oldspace memory usage.
This is another approach to solve an issue discussed at r43530.
  This feature is diabled as default.
  This feature measures an increment of memory consuption by oldgen
  objects. It measures memory consumption for each objects when
  the object is promoted. However, measurement of memory consumption
  is not accurate now. So that this measurement is `estimation'.
  To implement this feature, move memsize_of() function from
  ext/objspace/objspace.c and expose rb_obj_memsize_of().
  Some memsize() functions for T_DATA (T_TYPEDDATA) have problem to
  measure memory size, so that we ignores T_DATA objects now.
  For example, some functions skip NULL check for pointer.
  The macro RGENGC_ESTIMATE_OLDSPACE enables/disables this feature,
  and turned off as default.
  We need to compare 3gen GC and this feature carefully.
  (it is possible to enable both feature)
  We need a help to compare them.
* internal.h: expose rb_obj_memsize_of().
* ext/objspace/objspace.c: use rb_obj_memsize_of() function.
* cont.c (fiber_memsize): fix to check NULL.

ko1 c5e08b764e * add RUBY_TYPED_FREE_IMMEDIATELY to data types which only use
safe functions during garbage collection such as xfree().
  On default, T_DATA objects are freed at same points as fianlizers.
  This approach protects issues such as reported by [ruby-dev:35578].
  However, freeing T_DATA objects immediately helps heap usage.
  Most of T_DATA (in other words, most of dfree functions) are safe.
  However, we turned off RUBY_TYPED_FREE_IMMEDIATELY by default
  for safety.

ko1 dc626dbab3 * include/ruby/ruby.h: rename RARRAY_RAWPTR() to RARRAY_CONST_PTR().
RARRAY_RAWPTR(ary) returns (const VALUE *) type pointer and
  usecase of this macro is not acquire raw pointer, but acquire
  read-only pointer. So we rename to better name.
  RSTRUCT_RAWPTR() is also renamed to RSTRUCT_CONST_PTR()
  (I expect that nobody use it).

ko1 87d48d14a0 * vm_core.h, vm_trace.c: fix multi-threading bug for tracing.
Move `trace_arg' from rb_tp_t::trace_arg to rb_thread_t::trace_arg.
  `trace_arg' may changed by multiple threads.
  rb_thread_t::trace_arg can represent rb_thread_t::trace_running
  (null or non-null) and rb_thread_t::trace_running is removed.
  After that, `rb_tp_t' is not needed to check tracing or not
  (A running thread knows tracing or not). This is why I remove
  tp_attr_check_active() and make new function get_trace_arg().
  And this modification disable to work the following code:
  TracePoint.trace{|tp|
  Thread.new{p tp.event} # access `tp' from other threads.
  }
  I believe nobody mix threads at trace procedure.
  This is current limitation.
* cont.c (fiber_switch, rb_cont_call): use rb_thread_t::trace_arg
  instead of rb_thread_t::trace_running.
* test/ruby/test_settracefunc.rb: add a multi-threading test.

ko1 87e1616048 * vm.c: support variable VM/Machine stack sizes.
Specified by the following environment variaables:
  - RUBY_THREAD_VM_STACK_SIZE: vm stack size used at thread creation.
  default: 128KB (32bit CPU) or 256KB (64bit CPU).
  - RUBY_THREAD_MACHINE_STACK_SIZE: machine stack size used at thread
  creation. default: 512KB or 1024KB.
  - RUBY_FIBER_VM_STACK_SIZE: vm stack size used at fiber creation.
  default: 64KB or 128KB.
  - RUBY_FIBER_MACHINE_STACK_SIZE: machine stack size used at fiber
  creation. default: 256KB or 256KB.
  This values are specified at launched timing. You can not change
  these values at running time.
  Environ variables are only *hints* because:
  - They are aligned to 4KB.
  - They have minimum values (depend on OSs).
  - Machine stack settings are ignored by some OSs.
  Default values especially fiber stack sizes are increased.
  This change affect Fiber's behavior:
  (1) You can run more complex program on a Fiber.
  (2) You can not make many (thousands) Fibers because of
  lack of address space (on 32bit CPU).
  If (2) bothers you,
  (a) Use 64bit CPU with big memory, or
  (b) Specify RUBY_FIBER_(VM|MACHINE)_STACK_SIZE correctly.
  You need to choose correct stack size carefully. These values
  are completely rely on systems (OS/compiler and so on).
* vm_core.h (rb_vm_t::default_params): add to record above settings.
* vm.c (RubyVM::DEFAULT_PARAMS): add new constant to see
  above setting.
* thread_pthread.c: support RUBY_THREAD_MACHINE_STACK_SIZE.
* cont.c: support RUBY_FIBER_(VM|MACHINE)_STACK_SIZE.
* test/ruby/test_fiber.rb: add tests for above.
* test/ruby/test_thread.rb: ditto.

shugo 60d6038dda * revised r37993 to avoid SEGV/ILL in tests. In r37993, a method
entry with VM_METHOD_TYPE_REFINED holds only the original method
  definition, so ci->me is set to a method entry allocated in the
  stack, and it causes SEGV/ILL.  In this commit, a method entry
  with VM_METHOD_TYPE_REFINED holds the whole original method entry.
  Furthermore, rb_thread_mark() is changed to mark cfp->klass to
  avoid GC for iclasses created by copy_refinement_iclass().

* vm_method.c (rb_method_entry_make): add a method entry with
  VM_METHOD_TYPE_REFINED to the class refined by the refinement if
  the target module is a refinement.  When a method entry with
  VM_METHOD_TYPE_UNDEF is invoked by vm_call_method(), a method with
  the same name is searched in refinements.  If such a method is
  found, the method is invoked.  Otherwise, the original method in
  the refined class (rb_method_definition_t::body.orig_me) is
  invoked.  This change is made to simplify the normal method lookup
  and to improve the performance of normal method calls.

* vm_method.c (EXPR1, search_method, rb_method_entry),
  vm_eval.c (rb_call0, rb_search_method_entry): do not use
  refinements for method lookup.

* vm_insnhelper.c (vm_call_method): search methods in refinements if
  ci->me is VM_METHOD_TYPE_REFINED.  If the method is called by
  super (i.e., ci->call == vm_call_super_method), skip the same
  method entry as the current method to avoid infinite call of the
  same method.

* class.c (include_modules_at): add a refined method entry for each
  method defined in a module included in a refinement.

* class.c (rb_prepend_module): set an empty table to
  RCLASS_M_TBL(klass) to add refined method entries, because
  refinements should have priority over prepended modules.

* proc.c (mnew): use rb_method_entry_with_refinements() to get
  a refined method.

* vm.c (rb_thread_mark): mark cfp->klass for iclasses created by
  copy_refinement_iclass().

* vm.c (Init_VM), cont.c (fiber_init): initialize th->cfp->klass.

* test/ruby/test_refinement.rb (test_inline_method_cache): do not skip
  the test because it should pass successfully.

* test/ruby/test_refinement.rb (test_redefine_refined_method): new
  test for the case a refined method is redefined.

ko1 4a4a702e61 * vm_trace.c, vm_core.h: simplify tracing mechanism.
(1) add rb_hook_list_t data structure which includes
  hooks, events (flag) and `need_clean' flag.
  If the last flag is true, then clean the hooks list.
  In other words, deleted hooks are contained by `hooks'.
  Cleanup process should run before traversing the list.
  (2) Change check mechanism
  See EXEC_EVENT_HOOK() in vm_core.h.
  (3) Add `raw' hooks APIs
  Normal hooks are guarded from exception by rb_protect().
  However, this protection is overhead for too simple
  functions which never cause exceptions.  `raw' hooks
  are executed without protection and faster.
  Now, we only provide registration APIs.  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.

ko1 0a71db8a74 * vm_core.h: remove lfp (local frame pointer) and rename
dfp (dynamic frame pointer) to ep (environment pointer).
  This change make VM `normal' (similar to other interpreters).
  Before this commit:
  Each frame has two env pointers lfp and dfp.  lfp points
  local environment which is method/class/toplevel frame.
  lfp[0] is block pointer.
  dfp is block local frame. dfp[0] points previous (parent)
  environment pointer.
  lfp == dfp when frame is method/class/toplevel.
  You can get lfp from dfp by traversing previous environment
  pointers.
  After this commit:
  Each frame has only `ep' to point respective enviornoment.
  If there is parent environment, then ep[0] points parent
  envioenment (as dfp).  If there are no more environment,
  then ep[0] points block pointer (as lfp).  We call such ep
  as `LEP' (local EP).  We add some macros to get LEP and to
  detect LEP or not.
  In short, we replace dfp and lfp with ep and LEP.
  rb_block_t and rb_binding_t member `lfp' and `dfp' are removed
  and member `ep' is added.
  rename rb_thread_t's member `local_lfp' and `local_svar' to
  `root_lep' and `root_svar'.
  (VM_EP_PREV_EP(ep)): get previous environment pointer.  This macro
  assume that ep is not LEP.
  (VM_EP_BLOCK_PTR(ep)): get block pointer.  This macro assume
  that ep is LEP.
  (VM_EP_LEP_P(ep)): detect ep is LEP or not.
  (VM_ENVVAL_BLOCK_PTR(ptr)): make block pointer.
  (VM_ENVVAL_BLOCK_PTR_P(v)): detect v is block pointer.
  (VM_ENVVAL_PREV_EP_PTR(ptr)): make prev environment pointer.
  (VM_ENVVAL_PREV_EP_PTR_P(v)): detect v is prev env pointer.
* vm.c: apply above changes.
  (VM_EP_LEP(ep)): get LEP.
  (VM_CF_LEP(cfp)): get LEP of cfp->ep.
  (VM_CF_PREV_EP(cfp)): utility function VM_EP_PREV_EP(cfp->ep).
  (VM_CF_BLOCK_PTR(cfp)): utility function VM_EP_BLOCK_PTR(cfp->ep).
* vm.c, vm_eval.c, vm_insnhelper.c, vm_insnhelper.h, insns.def:
  apply above changes.
* cont.c: ditto.
* eval.c, eval_intern.h: ditto.
* proc.c: ditto.
* thread.c: ditto.
* vm_dump.c: ditto.
