Merging with a Merge Tree

If you have a merge tree, you merge into MariaDB as follows:

1. MariaDB merge trees are in the mergetrees repository. Add it as a new remote:

1. Check out the branch you want to update and merge, for example:

1. delete everything in the branch

2. download the latest released source tarball, unpack it, copy files into the repository:

• for InnoDB-5.6: use the content of the storage/innobase/ of the latest MySQL 5.6 source release tarball.

• for performance schema 5.6: use storage/perfschema, include/mysql/psi, mysql-test/suite/perfschema, and mysql-test/suite/perfschema_stress from the latest MySQL 5.6 source release tarball.

1. Now git add ., git commit (use the tarball version as a comment), git push

2. merge this branch into MariaDB

3. Sometimes after a merge, some changes may be needed:

• for performance schema 5.6: update storage/perfschema/ha_perfschema.cc, plugin version under maria_declare_plugin.

• for InnoDB-5.6: update storage/innobase/include/univ.i, setting INNODB_VERSION_MAJOR, INNODB_VERSION_MINOR, INNODB_VERSION_BUGFIX to whatever MySQL version you were merging from.
