High-level overview of sprint 47
Bootstrap Peers
We continued to review the process of bootstrap peers, see ouroboros-network#4555
CI / Tests
We investigated our CI issues. We found a memory leak in typed-protocols
function used for testing codecs which triggered out of memory manager (OOM) on
some platforms (typed-protocols#43); we also found a bug in the connection manager which resulted in CI
timeouts (see connection-manager-fix).
KeepAlive client
We found two small issues with the keep-alive client, which were addressed by Karl Knutsson (Cardano Foundation), ouroboros-network#4689.
Galois
We merged two large PRs prepared by Galois:
Cardano Network Service Assurance (CNSA)
Galois made the following progress on CNSA:
- a simple [InfuxDB] database backend has been added;
- the documentation has been updated;
- internal improvements to the code;
- progress on a new "CSNA analysis" that provides, for each sampler node, the block download throughput in bytes over time.
New CHaP Release
We cut a new release of ouroboros-netowrk packages to CHaP: chap#547
More details
CI / Tests
We improved the memory footprint of some of our tests by analysing a stream of
IOSim traces without retaining them, see ouroboros-network#4696
As a safety measure, we introduced an upper bound for heap memory used by test
artefacts in our nix tests. We use 200MB limit for all tests except for
network-mux tests which use 350MB limit, see ouroboros-network#4702.
We refactored one of our tests to use ephemeral ports thus allowing it to run concurrently, see ouroboros-network#4702.
We merged ouroboros-network#4623 which fixes a bunch of test failures.
All of them were due to a bug in test logic rather than a bug in production code.
Release Process
We updated our release process & associated scripts, see ouroboros-network#4705.
