Discard the received data on uTP content stream read timeout. Before the data was still added to the queue and being processed and should normally fail in validation. However as we know not all data got read it should not even move to the validation step. Added however a FIN send after the timeout instead of the delayed socket clean-up which does not make much sense in that scenario either. Basically either be nice and still send a FIN or just destroy the socket immediatly.
Portal Network Wire Protocol
Introduction
The fluffy/network/wire directory holds a Nim implementation of the
Portal Network Wire Protocol.
The wire protocol builds on top of the Node Discovery v5.1 protocol its
talkreq and talkresp messages.
For further information on the Nim implementation of the Node Discovery v5.1 protocol check out the discv5 page.
Test suite
To run the test suite specifically for the Portal wire protocol, run following commands:
git clone https://github.com/status-im/nimbus-eth1.git
cd nimbus-eth1
# To bring the git submodules up to date
make update
# Build & run Portal wire protocol encoding test
./env.sh nim c -r ./fluffy/tests/test_portal_wire_encoding
# Build & run Portal wire protocol network test
./env.sh nim c -r ./fluffy/tests/test_portal_wire_protocol
portalcli
This is a small command line application that allows you to run a node running Discovery v5.1 + Portal wire protocol.
Note: Its objective is only to test the protocol wire component, not to actually serve content. This means it will always return empty lists on content requests currently. Perhaps in the future some hardcoded data could added and/or maybe some test vectors can be created in such form.
The portalcli application allows you to either run a node, or to specifically
send one of the Portal message types, wait for the response, and then shut down.
Example usage
git clone https://github.com/status-im/nimbus-eth1.git
cd nimbus-eth1
# Build the fluffy tools
make fluffy-tools
# See all options
./build/portalcli --help
# Example command: Ping another node
./build/portalcli ping enr:<base64 encoding of ENR>
# Example command: Run a discovery + portal node
./build/portalcli --log-level:debug --bootstrap-node:enr:<base64 encoding of ENR>
