The MySQL Proxy was split into
- a chassis which handles cmdline, service, logging, plugin loading
- a core library for the life-cycle, network handling and protocol decoding
- a lua layer wrapping around the internals
- a set of plugins: proxy, admin, debug, replicant
It also contains a few tools that reuse the above libraries:
- mysql-binlog-dump
- mysql-myisam-dump
We dropped libcheck in favour of glib 2.16's g_test_* functions.
