Named Tunnels can exist without Ingress rules (They would default to
8080). Moreover, having this check also prevents warp tunnels from
starting since they do not need ingress rules.
This PR does two things:
It changes how we fallback to a lower protocol: The current state
is to try connecting with a protocol. If it fails, fall back to a
lower protocol. And try connecting with that and so on. With this PR,
if we fail to connect with a protocol, we will try to connect to other
edge addresses first. Only if we fail to connect to those will we
fall back to a lower protocol.
It fixes a behaviour where if we fail to connect to an edge addr,
we keep re-trying the same address over and over again.
This PR now switches between edge addresses on subsequent connecton attempts.
Note that through these switches, it still respects the backoff time.
(We are connecting to a different edge, but this helps to not bombard an edge
address with connect requests if a particular edge addresses stops working).
Remove send and return methods from Funnel interface. Users of Funnel can provide their own send and return methods without wrapper to comply with the interface.
Move packet router to ingress package to avoid circular dependency
For WARP routing the defaults for these new settings are 5 seconds for connect timeout and 30 seconds for keep-alive timeout. These values can be configured either remotely or locally. Local config lives under "warp-routing" section in config.yaml.
For websocket-based proxy, the defaults come from originConfig settings (either global or per-service) and use the same defaults as HTTP proxying.
This maximum grace period will be honored by Cloudflare edge such that
either side will close the connection after unregistration at most
by this time (3min as of this commit):
- If the connection is unused, it is already closed as soon as possible.
- If the connection is still used, it is closed on the cloudflared configured grace-period.
Even if cloudflared does not close the connection by the grace-period time,
the edge will do so.
- Move packages the provide generic functionality (such as config) from `cmd` subtree to top level.
- Remove all dependencies on `cmd` subtree from top level packages.
- Consolidate all code dealing with token generation and transfer to a single cohesive package.
