Support systemd socket activation

Details

    • 10.1.7-1, 10.1.7-2, 10.1.8-1, 10.1.8-3

    Description

      Supporting socket activation would make each of the following possible for admins:

      • Cleaner restarts (the listener socket stays open persistently)
      • Network namespace isolation, disallowing any network access beyond the inherited listener port (and connections accepted from it).
      • Lazy startup for densely hosted instances. (It's also possible with socket activation to start it eagerly, as usual.)
      • Running MariaDB on privileged ports without having to start it initially as root
      • Non-racy startup for services (like a PHP site) that depend on connecting to MariaDB. Because systemd opens listener sockets early in boot, they're available even while MariaDB is starting
      • Deeper integration into coming network support in future systemd releases

      Some examples in C are here:

      I am willing to sponsor development of this feature.
