Whenever cloudflared receives a SIGTERM or SIGINT it goes into graceful shutdown mode, which unregisters the connection and closes the control stream. Unregistering makes it so we no longer receive any new requests and makes the edge close the connection, allowing in-flight requests to finish (within a 3 minute period).
This was working fine for http2 connections, but the quic proxy was cancelling the context as soon as the controls stream ended, forcing the process to stop immediately.
This commit changes the behavior so that we wait the full grace period before cancelling the request
It might make sense for users to sometimes name their cloudflared
connectors to make identification easier than relying on hostnames that
TUN-7360 provides. This PR provides a new --label option to cloudflared
tunnel that a user could provide to give custom names to their
connectors.
This parameterizes relevant component tests by transport protocol
where applicable.
The motivation is to have coverage for (graceful or not) shutdown
that was broken in QUIC. That logic (as well as reconnect) is
different depending on the transport, so we should have it
parameterized. In fact, the test is failing for QUIC (and passing
for others) right now, which is expected until we roll out some
edge fixes for QUIC. So we could have caught this earlier on.
