- Indy-SDK build progress
- Issue: Mixed OS versions of Indy Node have issues:
- Issue: - running mixed nodes 16.04 and 20.04 a consensus problem occurs "in a while" (sometimes immediately, sometimes a few days has been seen)
- 2022.06.21
- Two efforts trying to replicate the problem Christian Bormann (rust script to generate load) and Gavin Bendixsen (PR to indy_node_container), working on adding a node
- At this point, the issue has not been replicated.
- There is an indy node load generator - https://github.com/hyperledger/indy-node/tree/master/scripts/performance
- Another plan of attack: Use old artifact to try to recreate, try again with RC and see if that replicates the issue.
- Note from Lynn: He has seen and documented consensus issues in the past – maybe this has nothing to do with 20.04.
- For example: 2 nodes went down seemingly together, restarted them and issue resolved.
- 2022.06.07
- Indicio team is working on a docker environment to replicate this, they are expecting to have something running in a few days.
- docker-compose, 4 nodes (3 16.04 and 1 20.04), running for a week, but not able to replicate the issue.
- Lynn to share how to do this publicly so that others could contribute.
- Put a folder into the indy-node-container repo about how to do it.
- Plan is to use indy-vdr to generate DIDs and publish them to the ledger.
- 2022.06.21
- Issue: - running mixed nodes 16.04 and 20.04 a consensus problem occurs "in a while" (sometimes immediately, sometimes a few days has been seen)
- Related work - Sovrin token-plugin repo being reworked to match indy-node/plenum.
- Mostly done the code.
- Working on the pipeline
- Linting issues documented and being cleaned
Future Calls
