Up from the previous 5 seconds. It's still short enough that the pages
shouldn't feel stale, but it further reduces the number of requests that
will reach the app.
Also moved this into a shared concern so we can adjust the caching rule
in one place.
In order to control routing dynamically, we need to expose some Beamer
information to the proxy.
The `beamer_writer` value is used by the proxy to keep track of which
node should receive write requests. When it changes due to a failover,
the proxy will update after seeing a new value in this header. We
provide this to the proxy in the `X-Writer` response header.
The `beamer_last_txn` value will be used to control writer pinning.
Setting it in the cookie here is the first stage of this. The second
stage will be to catch situations where a reader gets a request where
this header value is set to a large value than the reader has seen; when
that happens if means there's a risk of reading stale data, so rather
than serve the request we should request the proxy to reproxy it back to
the writer.
We also set `X-Kamal-Target` in the response to match the
`X-Kamal-Target` that was set in the request; this lets us see which
proxy target served each request, which is useful for diagnostics.
- New untenanted Identity and Membership models
- New `identity_token` cookie with path "/" holds state across tenants
We're not sure whether the untenanted database will be sqlite or
MySQL, and so I've been careful to minimize
- database reads, placing them behind etags and caching
- database writes, only writing when a new Session is created (login)
Note that we track two things in the identity_token cookie: a signed
id, and the updated_at for the underlying Identity object. This allows
us to effectively cache on the Identity without having to hit the
database, by using an Identity::Mock object that is compatible with
etag and cache methods.
The new integration test shows the desired user-facing behavior, which
is to make it easy to login without a tenanted URL and to jump between
tenants.
- the untenanted "login_help" page shows all linked memberships
- the jump menu shows all linked memberships (except the current)
Also introduced a utility script to populate existing employee
Identities, grouping accounts by email address.
