Error output for dynamic server creation if invalid lb algo has changed
since previous commit :
MINOR: server: fix doc/trace on lb algo for dynamic server creation
The vtest regex should have been updated has well to match it.
Add an empty expect statement after the 'enable server' cli command.
This ensures that the command has been properly handled by haproxy and
its processing is over.
It should fix the unstable behavior of the test which causes reports of
503 even after the server has been enabled.
This should fix the github issue #1188.
Allow to specify the mux proto for a dynamic server. It must be
compatible with the backend mode to be accepted. The reg-tests has been
extended for this error case.
Write a regtest for the cli command 'add server'. This test will execute
some invalid commands and validates the reported error. A client will
then try to connect to a dynamic server just created and activated.
