- If the timing is correct, a delay in the test's select might see the
doneCh signal before the renew channels signal. If that happens, the
test fails as it assumes we will receive signals across different
channels in order.
- Rework the test to make sure that we read from the renew channel if expected
and the done channel so that any errors might not be escaping from detection
on a renew.
* Sync up Agent and API's renewers.
This introduces a new type, LifetimeWatcher, which can handle both
renewable and non-renewable secrets, modeled after the version in Agent.
It allows the user to select behavior, with the new style being the
default when calling Start(), and old style if using the legacy Renew()
call.
No tests have been modified (except for reflect issues) and no other
code has been modified to make sure the changes are backwards
compatible.
Once this is accepted I'll pull the Agent version out.
* Move compat flags to NewRenewer
* Port agent to shared lifetime watcher lib
* Add grace period calculation logic to renewer
* Update lease renewer logic.
It is believed by myself and members of the Nomad team that this logic
should be much more robust in terms of causing large numbers of new
secret acquisitions caused by a static grace period. See comments in the
code for details.
Fixes#3414
* Fix some commenting and fix tests
* Add more time to test so that integ tests don't time out
* Fix some review feedback
