Module Tezos_p2p_test_common.Node
Source
Simple p2p message used by the nodes.
Ping
is a none-message used by nodes in simple communication tests.BigPing
is used to add arbitrary long data (similar to mempools sent in the actual network) to test bandwidth and chunks splitting.

t
is a simple p2p nodes.

int ->
Tezos_base.TzPervasives.P2p_addr.t ->
(Tezos_base.TzPervasives.P2p_point.Id.t * Unix.file_descr) list
gen_points npoints addr
generates npoints
points using the given addr
and an unused port given by the operating system by binding a fresh socket to the port 0
.
These sockets are left open and returned by the function with the generated point, so that the operating system cannot reuse this port while the socket is opened.
The returned sockets are also configured with option SO_REUSEPORT
so that user can bind its own socket using the generated point when desired. When a socket has finally been bounded to the given port, the user must close the socket to avoid file descriptor leaks.

detach_nodes f points
creates a network with one node for each points
. f
is the behavior of each node. If the network is alive after ?timeout
seconds, if any is provided, the Timeout
error is returned. ?prefix
associates a prefix used for logs to each nodes
. ?min_connections
, ?max_connections
, ?max_incoming_connections
, ?p2p_versions
and ?msg_config
are used to configure the connect handler of each nodes. ?trusted
is used to configure the pool of each nodes.
With each point of points
a file descriptor generated by the system that holds the point should be given. This file descriptor will be properly closed by this function. See gen_points
for more details.
