Connections from cloudflared to Cloudflare edge are long lived and may
break over time. That is expected for many reasons (ranging from network
conditions to operations within Cloudflare edge). Hence, logging that as
Error feels too strong and leads to users being concerned that something
is failing when it is actually expected.
With this change, we wrap logging about connection issues to be aware
of the tunnel state:
- if the tunnel has no connections active, we log as error
- otherwise we log as warning
* `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.
The default max streams value of 100 is rather small when subject to
high load in terms of connecting QUIC with streams faster than it can
create new ones. This high value allows for more throughput.
Go's client defaults to chunked encoding after a 200ms delay if the following cases are true:
* the request body blocks
* the content length is not set (or set to -1)
* the method doesn't usually have a body (GET, HEAD, DELETE, ...)
* there is no transfer-encoding=chunked already set.
So for non websocket requests, if transfer-encoding isn't chunked and content length is 0, we dont set a request body.
ServeControlStream accidentally became non-blocking in the last quic
change causing stream to not be returned until a SIGTERM was received.
This change makes ServeControlStream be non-blocking for QUIC streams.
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.
