Mavryk_proxy.Proxy_services
exception Rpc_dir_creation_failure of Mavryk_base.TzPervasives.tztrace
Exception used by the proxy mode when creation of the input environment (of the RPC handler) fails. This exception is used to temporarily escape from the monad, because at the point of throwing, the code is NOT in tzresult Lwt.t
. As it's dealing with resto APIs it's in an Lwt.t
-only monad. This exception is injected back in the tzresult Lwt.t
monad at the point where it is caught (with Lwt.catch
).

mavryk-proxy-server
is running. The sleep
field is implemented by Lwt_unix
.sleep. We don't want to depend on it directly (for compiling to Javascript), hence this field. The Ptime.span option
field is the value of argument --sym-block-caching-time
. The (Context_hash.t -> Proxy_delegate.t tzresult Lwt.t) option
value is constructed from argument --data-dir
: if the argument is present, this value represents how data is looked up in the data-dir of a running node.
Whether using the light mode or the proxy mode (remember that the light mode is a different instance of the proxy mode (see srcs/lib_proxy/README_LIGHT.md for documentation) and whether mavkit-client
or mavryk-proxy-server
is running.
