Fixes #338.
The problem was that if your header command was something like
auth --url=$CODER_URL
, it would get expanded as part of executing the proxy command and you end up withauth --url=
sinceCODER_URL
is not set.We want to pass it literally to the binary so that it can then be expanded in the binary when it executes the header command, since the binary will set
CODER_URL
when spawning.An alternative would be to set
CODER_URL
when the proxy command is spawned, but I am not sure we can as I think it would be using the current process environment (via that SSHJ library I think). Maybe there is a way to mutate the current environment, but a quick look says no.
