Overview of sprint 95
Mithril
We've been working on integrating Mithril signature verification into
dmq-node. This involves implementing the necessary logic to handle and verify
signatures, ensuring that the node can correctly process Mithril-related data.
Progress is being tracked in issue#5175 and issue#5176.
Cardano-Node
We worked on configuration and tracing improvements for the upcoming
cardano-node 10.6 release. The focus was on enhancing the user experience in
Genesis and Praos modes by refining how the network topology file is handled.
Specifically, we addressed issues where the topology file contains bootstrap
peers and genesis snapshot file locations, which are only relevant in one of the
modes. The goal is to ensure that parsing errors are minimised and that appropriate
log messages are emitted instead of errors in specific scenarios. Detailed
corner cases are documented in issue#6304.
Tx-Submission
We wrote a microbenchmark to evaluate the performance of the new tx-submission decision logic. The results will help identify any performance bottlenecks and guide further optimisations. See pr#5191.
Chain-Sync Protocol Specification Update
The specification of the chain-sync mini-protocol has been relaxed to reflect
the Cardano-Node implementation more accurately. The changes include
allowing the server to send MsgRollBackward after sending MsgFindIntersect
allowing the rollback to a point before the found intersection point. See
pr#5187.
Disconnection Reason Propagation
After a discussion in the networking working group, we found out that we could improve the debugging experience for SPOs by propagating the disconnection reason from the low-level connection manager to the inbound / outbound governor. This will allow SPOs to understand better why a connection was dropped. The work is tracked in pr#5189.
QuickCheck-2.15 and 2.16
We relaxed the bounds of QuickCheck dependency for the upcoming
cardano-node-10.6 release for a smoother transition, see pr#5190.
