Bug #19891: rb_mRubyVMFrozenCore is reported by DTrace but ignored by TracePoint
https://bugs.ruby-lang.org/issues/19891
* Author: vo.x (Vit Ondruch)
* Status: Open
* Priority: Normal
* ruby -v: ruby 3.3.0dev (2023-09-05 master 7c8932365f) [x86_64-linux]
* Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN
----------------------------------------
This is related to #18257 where I wonder why rb_mRubyVMFrozenCore is ignored by TracePoint (if I am not mistaken) [1]:
~~~
if (ec->trace_arg == NULL && /* check reentrant */
trace_arg->self != rb_mRubyVMFrozenCore /* skip special methods. TODO: remove it. */) {
~~~
This was introduced in commit:git|1be7c799e6ed39f7ac41906c05db149e8c391add but hard to guess what was the reason. If there were issues similar to @18257 or if it is by design.
The `TODO` part was introduced by commit:git|4a4a702e61d1c5585d522f1185a82a5685c554f6 which also does not give a clue what is intention here.
Generally, my point is that it is strange that DTrace would report about rb_mRubyVMFrozenCore while TracePoint is happy to skip it.
