Observations:

  1. All the non-Oracle contributors work for SkySQL (and worked for Monty Program before that)
  2. Even when you go back to MariaDB 5.5.23 I can only find evidence for a maximum of 2-3 external contributions of code to MariaDB since then.
  3. In the same time frame (5.5.23-5.5.32) I see 1 or 2 going into Oracle trees, so it’s roughly the same.
  4. If you look at the contributors from Oracle over 5.5.23 to 5.5.32 there are closer to twice as many as the 40 listed above.

Somebody please correct me if I’m wrong here… perhaps MariaDB guys are just really bad at clearly marking commits that come from elsewhere? I’ve looked for “patch.*by”, “original” and “ontributed” and only turned up the above.
