It is sometimes useful to update the running code and / or configuration of a
network service, without disrupting existing connections. Usually, this is
achieved by starting a new process, somehow transferring clients to it and
then exiting the old process.
.
There are many ways to implement graceful upgrades. They vary wildly in the
trade-offs they make, and how much control they afford the user. This library
has the following goals:
- No old code keeps running after a successful upgrade
- The new process has a grace period for performing initialisation
- Crashing during initialisation is OK
- Only a single upgrade is ever run in parallel
