As usual, those contributions cover many different sections of MySQL. If you have patches and you also want to be part of the MySQL Contributors, it’s easy, you can send Pull Requests from MySQL’s GitHub repositories or send your patches on Bugs MySQL (signing the Oracle Contributor Agreement is required).

And don’t forget, that if you want to extend MySQL, the best way is to create a component. Now there is a complete series to learn how to start using the MySQL Component Infrastructure (part 1) !

Thank you again to all our contributors !

  1. Interesting to see there are more information about bug fixes in this blog post than in the release notes. Unless I am mistaken, these bug numbers are not un the Release Notes:
    – #104186 – Too few chunk files are created for hybrid hash join – Øystein Grøvlen
    – #102733 (private) – Server crash in fil_space_is_being_truncated – Zheng Lai
    – #104447 (private) – Fix freed memory access in performance schema tab – Facebook
    – #104593 (private) – MySQL crashes while executing reset slave all – Brian Yue

    • When private bugs are fixed by contributions, they are listed with the Oracle internal bug number. Also I’m verifying why 3 bugs (including Øystein’s one) because they ended up in two different versions.
