The team has focused on debuging & fixing bugs for the P2P single relay release, which included
- diagnosing, fixing and writing tests for a bug in
peer-state-actionswhich fortunately hasn't been released;
- diagnosing & preventing misconfiguration of DNS
We also focused on developing peer sharing. We also held a session with the scientists on eclipse evasion.
P2P Network Stack
During the past two weeks the team focused on p2p single relay release and peer sharing. We found and fixed an important bug recently introduced in one of the components of p2p networking stack (fortunately never released). Together with a fix, we designed a unit test diffusion simulation as well as quickcheck property test (both could reproduce it). We also changed the code in a way that if such a bug is reintroduced in the future, it will be obvious to diagnose. For more see:
Initial benchmarking run of the P2P code was executed. The results where unlike what we see on the mainnet. We found a possible misconfiguration of the cluster (caused by 0 TTL on domain names), which could be the direct cause of it. We wrote a PR which rules out such misconfiguration. We are awaiting on the next benchmarking results. See more at:
We also started working on P2P single relay release. The PR
includes 108 patches cherry-picked from the
master branch. We started
working toward integration these changes against the release branch of
cardano-node. Early next week we ought to be able to have an early version
cardano-node with non experimental P2P support!
For more detailed release plan please see P2P - Single Relay issue.
We identified and fixed missing error reporting in consensus initialisation phase. See more at ouroboros-network#4015
We also made changes in
cardano-node in order to give better experience for
node operators. This includes updating severities of some of the traces as
well as implementing new format of the p2p topology file. For more see:
We continued working on implementation of peer sharing. We have an early
implementation which will be reviewed and analysed in next weeks. We started
cardano-node integration. We need
PR #4392 to be merged
before such integration will be able to land in
cardano-node, although this
is not blocking us currently. See more at:
We held a session which included Alexander Russel, Sandro Coretti-Drayton and
Nick Frisby from the consensus team. We discussed high lever design of the
eclipse evasion scheme, which is important for the design and implementation of
ouroboros-genesis. We got a positive feedback from the researchers.
In this period we made little progress towards releasing
IO-Sim on Hackage.
A single PR which added
a few missing instances of the
We made sure the CI runs for PRs which comes from forks (which is important to accept contributions from 3rd parties).
Mithril Cardano Integration
We held initial discussions with Arnaud Bailly about possible path to integrate
cardano-node and take advantage of the
