Overview of [sprint 73][sprint-73]​

Ouroboros-Network-0.18 release​

We released ouroboros-network-0.18. The main features are:

• integration with typed-protocols-0.3
• cardano-client library doesn't depend on the non-p2p stack
• We expose connectToWithMux family of functions in ouroboros-network which give access to the underlying [Mux handle][mux-handle].
• Added NodeToClientV_19: to support the new GetLedgerPeerSnapshot query in local-state-query mini-protocol [ouroboros-consensus#1067].

See full [the list of PRs][ouroboros-network-0.18] included in this release. ouroboros-network-0.18 was integrated with ouroboros-consensus ([ouroboros-consensus#1223])

Tx-Submission​

We continued working on tx-submission and monitoring its performance.

Ouroboros-Network - Mithril Design​

We internally discussed how to support the [Mithril design][cip#137]. In In the near future, we will be able to socialise the report we've been working on.

Code Refactoring​

We reorganised some of our substysems to use qualified imports with simplified names:

• [ouroboros-network#4990] (connection-manager, inbound-governor)
• [ouroboros-network#4997] (network-mux)

We also removed deprecated APIs in [ouroboros-network#4998]sim#182]

Overview of sprint 71​

Security Policy​

According to IntersectMBOs Open-Source Committee guidance, we updated our security policy.

Tx-Submission​

We have been working on the integration of the new tx-submission inbound side with cardano-node.

New Typed-Protocols API​

We published typed-protocols-0.3.0.0 to CHaP. It includes changes to the typed-protocols-stateful API. The added changes allow us to simplify LocalStateQuery mini-protocol, particularly the MsgResult doesn't include the request type (e.g. query result). It is provided to the codec using the associated local state mechanism instead. See typed-protocols#61, chap#911.

The integration of typed-protocols-0.3.0.0 with ouroboros-network was merged to the master branch, see ouroboros-network#4935.

The integration of this work stream with cardano-node is tracked on ouroboros-network#4936.

cardano-node-9.3​

We started working on cardano-node-9.3 release.

CI​

• We improved the check-stylish.sh script: ouroboros-network#4963.
• We refactored the ouroboros-network.cabal file: ouroboros-network#4964.
• We refactored the nix configuration: ouroboros-network#4968, which is continued in ouroboros-network#4969.
• We wrote a patch to fix the nightly build: ouroboros-network#4970.

High-level overview of sprint 70​

Cardano CLI​

cardano-cli ping command cannot send pings over unix sockets using node-to-client mini-protocol (since it doesn't support it). In that case, the command will now show a user-friendly error message. See cardano-cli#49.

Mithril​

We held a session with the mithril team to discuss design & implementation of Mithril using ouroboros-network.

Ouroboros-Network​

TxSubmission Logic​

We continued working on tx-submission logic. We developed new tests that run several simulated outbound peers offering transactions and a single inbound peer governed by the new tx-submission logic. Ref ouroboros-network#3311.

The next step is to clean the branch and integrate it with ouroboros-consensensus & cardano-node for early e2e tests.

Bulk-Sync for Genesis​

We reviewed the new bulk-sync application for Genesis mode, see ouroboros-network#4919.

Typed-Protocols​

We reviewed the new typed-protocols API PR. It was recently merged & published to CHaP. Once Haskell.Nix has better support for public sub-libraries, we will package all the libraries in one package and publish it on Hackage. Ref: typed-protocols#52.

The next step is to update, review the integration PR in ouroboros-network, see ouroboros-network#4935.

Nightly Tests​

We fixed a long-due failure on a nightly test. The failure was due to IOSimPOR ability to reorder simulated IO actions, resulting in a wrong order of events. So, it's not a bug in the production code but in the test itself. See ouroboros-network#4948.

Updated readme file​

We updated the dependency graph in our README.md file.

Next Sprint​

High-level overview of sprint 69​

Ouroboros-Network-0.17.1.x​

We released ouroboros-network-0.17.1.{0,1} which is being integrated with cardano-node-9.2, see releases.

Tx-Submission​

We continued working on tests of the new tx-submission application, ouroboros-network#3311, ouroboros-network#4928.

Typed Protocols​

The new typed-protocols API is under review, typed-protocols#52

IOSim​

We released a new version of io-classes & io-sim to Hackage:

• io-classes-1.7.0.0
• [io-sim-1.6.0.0]

High-level overview of sprint 68​

Peer Sharing​

Karl Knutsson (CF) produces graphs which show how peer sharing usage expands on mainnet.

Private relays in the last graph are relays which we are not certain that are registered on the chain.

Typed Protocols​

We conducted an investigation whether the new proposed typed-protocols version (see typed-protocols#52 introduces any performance regression. No regression was found when running a cardano-node (v9.1.0 vs a modified version using the new typed-protocols API) the benchmarking cluster. Also no regression was observed when syncing mainnet. The graph below shows accumulated size of block downloaded over time for both nodes:

The following draft PRs are openned:

• typed-protocols#52
• ouroboros-network#4935 - Ouroboros-Network changesd
• ouroboros-consensus#1223 - Ouroboros-Consensus changes
• cardano-api#619
• cardano-cli#870
• ekg-forward#33
• cardano-node#5956 - cardano-node version using new typed-protocols API

cardano-cli ping​

Fixed a bug in which cardano-cli ping exited with wrong exit code when a wrong network magic was supplied, see ouroboros-network#4865.

cardano-cli ping will also now report the remote IP address and port when querying the tip:

> cardano-cli ping -h backbone.mainnet.cardanofoundation.org -p3001 -t -j -q | jq
{
  "tip": [
    {

    }
 ]
}

See ouroboros-network#4931.

Tx-Submission​

We continued writing tests for the new tx-submission application.

We started extending typed-protocols codec to have access to both raw bytes and decoded transactions in the tx-submission mini-protocol. See ouroboros-network#4934.
