Overview of sprint 83
High-level overview
SRV support (Cardano, Mithril)
We merged ouroboros-network#5018 which adds support for SRV in ouroboros-network.
However, we still need to make a decision whether we require that all Cardano
SRVs start with _cardano._tcp, or we leave it open for the future. The
former would allow us to use SRVs for different applications, e.g.
_mithril._tcp for the mithril diffusion. If that would be the case then we'd
prepend _cardano._tcp to what we find in the SRV field of a registration
certificate, e.g. prepend _cardano._tcp by cardano-node's diffusion, and
_mithril._tcp by the mithril diffusion. The other possibility is to extend
the registration certificate to include the addresses of mithril nodes.
Mithril
We started working on a development plan for Mithril diffusion, [ref][mithirl-diffusion] (note that this is a work in progress).
We also have been working on moving network-related code from the
cardano-node to the cardano-diffusion library in ouroboros-network. In the
future, this will allow us to share parts of it in the Mithril diffusion [ouroboros-newtork#5082].
Documentation
We improved our CDDL specifications by annotating which codecs require definite / in-definite encoding of lists & maps, see ouroboros-network#5089.
Mux
Karl Knutsson (CF) has been working on performance improvements in the
multiplexer (network-mux library), ouroboros-network#5093.
Server-side performance considerations
Karl Kntusson (CF) noticed a performance bottleneck in the responder (server) side of the p2p diffusion layer. We've started working on addressing this issue.
Tx-Submission logic
We continued reviewing/improving the tx-submission PR ouroboros-network#4887.
