[Feature #19117]
Add a new API rb_profile_thread_frames(), which is essentialy a
per-thread version of rb_profile_frames().
While the original rb_profile_frames() always returns results about the
current active thread obtained by GET_EC(), this new API takes a Thread
to be profiled as an argument.
This should come in handy when profiling I/O-bound programs such as
webapps, since this new API allows us to learn about Threads performing
I/O (which do not have the GVL).
Profiling worker threads (such as Sidekiq workers) may be another
application.
Implements [Feature #10602]

If `assert_equal(backtrace_locations.size, profile_frames.size)` in
`TestProfileFrames#test_matches_backtrace_locations_main_thread`
failed, we do not have enough information about it like that:
```
1) Failure:
TestProfileFrames#test_matches_backtrace_locations_main_thread [/home/runner/work/ruby/ruby/src/test/-ext-/debug/test_profile_frames.rb:148]:
<31> expected but was
<30>.
```
This patch shows both `backtrace_locations` and `profile_frames`
if failed.
[Feature #19755]
Before (in /tmp/test.rb):
```ruby
Object.class_eval("p __FILE__") # => "(eval)"
```
After:
```ruby
Object.class_eval("p __FILE__") # => "(eval at /tmp/test.rb:1)"
```
This makes it much easier to track down generated code in case
the author forgot to provide a filename argument.
The `rb_profile_frames` API did not skip the two dummy frames that
each thread has at its beginning. This was unlike `backtrace_each` and
`rb_ec_parcial_backtrace_object`, which do skip them.
This does not seem to be a problem for non-main thread frames,
because both `VM_FRAME_RUBYFRAME_P(cfp)` and
`rb_vm_frame_method_entry(cfp)` are NULL for them.
BUT, on the main thread `VM_FRAME_RUBYFRAME_P(cfp)` was true
and thus the dummy thread was still included in the output of
`rb_profile_frames`.
I've now made `rb_profile_frames` skip this extra frame (like
`backtrace_each` and friends), as well as add a test that asserts
the size and contents of `rb_profile_frames`.
Fixes [Bug #18907] (<https://bugs.ruby-lang.org/issues/18907>)
Right now `SomeClass.method` is properly named, but `SomeModule.method`
is displayed as `#<Module:0x000055eb5d95adc8>.method` which makes
profiling annoying.
* vm_backtrace.c (rb_debug_inspector_open): escape all env using
`rb_vm_stack_to_heap()` before making bindings.
[Bug #15105]
There is a complicated story of this issue:
Without this patch, IFUNC frame does not escaped. A IFUNC frame
points to CFUNC ep as previous ep. However, CFUNC ep can be escaped
because of making bindings of Ruby level frames.
IFUNC's ep can points to invalidated ep and `rb_iter_break()` will
fail. This is why `any?` fails.
* test/-ext-/debug/test_debug.rb: add a test.

rb_profile_frames was always behaving as if the value given for the
start parameter was 0.
The reason for this was that it would check if (start > 0) { then
continue without updating the control frame pointer or anything other
than decrementing start.

When you change this to true, you may need to add more tests.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@53141 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* internal.h, iseq.c (rb_iseq_klass): remove it because
rb_iseq_t::klass is removed.
* vm_insnhelper.c (vm_super_outside): do not see cfp->iseq, but
check callable method entry on a frame.
This fix simplify the logic to search super class.
* test/ruby/test_method.rb: support super() from Proc.
Now, [Bug #4881] and [Bug #3136] was solved.
* proc.c (rb_mod_define_method): catch up this change.
* vm.c (vm_define_method): ditto.
* vm_backtrace.c (rb_profile_frames): now, each `frame' objects
are rb_callable_method_entry_t data or iseq VALUEs.
This fix introduce minor compatibility issue that
rb_profile_frame_label() always returns
rb_profile_frame_base_label().
* test/-ext-/debug/test_profile_frames.rb: catch up this change.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@51166 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
* test/-ext-/debug/test_profile_frames.rb (test_profile_frames):
assert first_lineno, only the top level of methods for the time
being.
git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@43286 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
vm_backtrace.c (rb_profile_frame_full_label): add new C API
rb_profile_frame_full_label() which returns label with
qualified method name.
Note that in future version of Ruby label() may return
same return value of full_label().
* ext/-test-/debug/profile_frames.c,
test/-ext-/debug/test_profile_frames.rb: fix a test for this change.

The order of making binding should be stack (frame) top to bottom.
[Bug #7635]
And also fix issue of collecting klass. Collecting klass is same
as TracePoint#defined_class.
(previous version, it returns T_ICLASS (internal objects).
* test/-ext-/debug/test_debug.rb: add a test.
* ext/-test-/debug/extconf.rb, init.c, inspector.c: ditto.
* vm_backtrace.c: remove magic number and add enum CALLER_BINDING_*.
* vm_backtrace.c, include/ruby/debug.h: add new C api (experimental)
rb_debug_inspector_frame_self_get().
* vm.c, vm_core.h, vm_trace.c: move decl. of
rb_vm_control_frame_id_and_class() and constify first parameter.
