- Cache the username and last verified time associated with each logged-in
backend
- In the HTTP backend, verify the access token explicitly at most once
per hour
This trades off a little bit of usability for improved inner-loop
latency: if a user's API token becomes invalid less than an hour after
it was last verified, the user will see 4xx errors when attempting stack
operations rather than seeing the login prompt.
We move the implementations of our secrets managers in to
`pkg/secrets` (which is where the base64 one lives) and wire their use
up during deserialization.
It's a little unfortunate that for the passphrase based secrets
manager, we have to require `PULUMI_CONFIG_PASSPHRASE` when
constructing it from state, but we can make more progress with the
changes as they are now, and I think we can come up with some ways to
mitigate this problem a bit (at least make it only a problem for cases
where you are trying to take a stack reference to another stack that
is managed with local encryption).
