This PR starts a separate server for proxy-dns if the configuration is
available. This fixes a problem on cloudflared not starting in proxy-dns
mode if the url flag (which isn't necessary for proxy-dns) is not
provided. Note: This is still being supported for legacy reasons and
since proxy-dns is not a tunnel and should not be part of the
cloudflared tunnel group of commands.
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).
Before this change when running cloudflare tunnel command without any
subcommand and without any additional flag, we would spin up a
QuickTunnel.
This is really a strange behaviour because we can easily create unwanted
tunnels and results in bad user experience.
This also has the side effect on putting more burden in our services
that are probably just mistakes.
This commit fixes that by requiring user to specify the url command
flag.
Running cloudflared tunnel alone will result in an error message
instead.
cloudflared shows possible directories for config files to be present if
it doesn't see one when starting up. For remotely configured files, it
may not be necessary to have a config file present. This PR looks to see
if a token flag was provided, and if yes, does not log this message.
Previously allowing the reconnect signal forcibly close the connection
caused a race condition on which error was returned by the errgroup
in the tunnel connection. Allowing the signal to return and provide
a context cancel to the connection provides a safer shutdown of the
tunnel for this test-only scenario.
* `max-fetch-size` can now be set up in the config YAML
* we no longer pass that to filter commands that filter by name
* flag changed to signed int since altsrc does not support UInt flags
* we now look up each non UUID (to convert it to a UUID) when needed, separately
This can be useful/important for accounts with many tunnels that exceed
the 1000 default page size.
There are various tunnel subcommands that use listing underneath, so we make
that flag a tunnel one, rather than adding it to each subcommand.
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.
