Way to combine dumps into one flamegraph? about stackprof HOT 2 OPEN

Ran in to same problem here.

This seems to be caused by Report#+, which simply ignores raw samples in the merge process. This patch worked for me:

--- lib/stackprof/report.rb
+++ lib/stackprof/report.rb
@@ -617,7 +617,8 @@ module StackProf
         samples: d1[:samples] + d2[:samples],
         gc_samples: d1[:gc_samples] + d2[:gc_samples],
         missed_samples: d1[:missed_samples] + d2[:missed_samples],
-        frames: frames
+        frames: d1[:frames].merge(d2[:frames]),
+        raw: d1[:raw] + d2[:raw],
       }
 
       self.class.new(data)

I've also patched frames to a simple Hash#merge, since print_flamegraph expects unnormalized frames. Pretty sure that this isn't the correct way to fix this, but it works, at least 🤷‍♂️

Has this ever been integrated? I'm having the same issue.
