Bug #5292: Access to GC::Profiler Records

• Status: Closed

Could the method gc_profile_record_get be made part of the GC::Profiler class? It returns an array of hashes of various interesting GC measurements.

I'd like ruby-prof to hook into it. Unfortunately, only textual output is currently supported via gc_profile_result. And parsing that output would be a pain.

To do this:

• 1 line patch to gcc.c:

rb_define_singleton_method(rb_mProfiler, "records", gc_profile_record_get, 0);

• Is is a safe change since the result is a newly created array of hashes each time.

• Its useful for performance analysis tools (like ruby-prof)

Would be great to have this in 1.9.3 if at all possible.

Thanks - Charlie

Sorry - I missed that there was already a request for this two months ago - see #4991. It includes the 1 line patch as well as documentation.

Could it be applied?

Thank you.

Can this be part of 1.9.3 or is it too late?

Sorry, it's too late, because 1.9.3 branch already in feature freeze.
