Previously, it was only possible to retry the same request on a
different protocol name that had the exact same binary payloads.
Introduce a way of trying a different request on a different protocol if
the first one fails with Unsupported protocol.
This helps with adding new req-response versions in polkadot while
preserving compatibility with unupgraded nodes.
The way req-response protocols were bumped previously was that they were
bundled with some other notifications protocol upgrade, like for async
backing (but that is more complicated, especially if the feature does
not require any changes to a notifications protocol). Will be needed for
implementing https://github.com/polkadot-fellows/RFCs/pull/47
TODO:
- [x] add tests
- [x] add guidance docs in polkadot about req-response protocol
versioning
Closes#1591.
The purpose of this PR is filter out backing statements from the network
signed by disabled validators. This is just an optimization, since we
will do filtering in the runtime in #1863 to avoid nodes to filter
garbage out at block production time.
- [x] Ensure it's ok to fiddle with the mask of manifests
- [x] Write more unit tests
- [x] Test locally
- [x] simple zombienet test
- [x] PRDoc
