Code migration guide for partner-chains v1.1.0 to v1.2.0

partner-chains-node-commands

Code supporting generate-signatures, get-ariadne-parameters and get-registration-status commands has been moved from the reference node to library crates of partner-chains.
Moving this code to library crates will make it less code to update in the future.
Any node has to recognize these commands in order to be a valid partner chain node.

1. Add partner-chains-node-commands crate to your dependencies in Cargo.toml.

2. Modify Subcommand enum (in reference implementation it is in cli.rs file):

#[derive(Debug, clap::Subcommand)]
pub enum Subcommand {
	// ... other subcommands
	#[clap(flatten)]
	PartnerChains(PartnerChainsSubcommand<YourSidechainParams>),
	// ... other subcommands
}

, where YourSidechainParams is the struct that holds the parameters of your partner chains. Reference implementation uses chain_params::SidechainParams struct.

3. Wire all the partner chains commands in the run function of your node. For example:

pub fn run() -> sc_cli::Result<()> {
	let cli = Cli::from_args();

	match &cli.subcommand {
		// ... other commmands
		Some(Subcommand::PartnerChains(cmd)) => {
			let make_dependencies = |config| {
				let components = service::new_partial(&config)?;
				Ok((components.client, components.task_manager, components.other.3.candidate))
			};
			partner_chains_node_commands::run(&cli, make_dependencies, cmd.clone())
		},
		/// ... other commands

4. Cleanup cli.rs and mod.rs files in case you node had copy-paste implementation of these commands.

polkadot-sdk

partner-chains toolkit has migrated from custom fork of polkadot-sdk to paritytech fork of polkadot-sdk.
This changes the structure of crates used by partner-chains toolkit.

Please update your dependencies to reflect this change and depend only on the paritytech fork.
Replace git = "https://github.com/input-output-hk/polkadot-sdk.git", tag = "partnerchains-stable2407" with "https://github.com/paritytech/polkadot-sdk.git", tag = "polkadot-stable2407-2" in your cargo files.

sc-partner-chains-consensus-aura

input-output-hk fork of polkadot used modified sc-consensus-aura crate to inject slot in inherent data providers and to have access to inherent digest (Cardano stable block hash).
These modifications are moved to partner-chains crate sc-partner-chains-consensus-aura that depends on unmodified sc-consensus-aura crate from paritytech/polkadot-sdk.

Add sc-partner-chains-consensus-aura to your dependencies in Cargo.toml.

Code changes related wiring this change are (service.rs file in reference node implementation):

1. Replace use sp_partner_chains_consensus_aura::CurrentSlotProvider; with use sc_consensus_aura::CurrentSlotProvider;.

2. Replace sc_consensus_aura::import_queue with sc_partner_chains_consensus_aura::import_queue.

3. Replace sc_consensus_aura::start_aura with sc_partner_chains_consensus_aura::start_aura.

4. Use custom BlockProposerFactory from sc-partner-chains-consensus-aura crate:

let basic_authorship_proposer_factory = sc_basic_authorship::ProposerFactory::new(
	task_manager.spawn_handle(),
	client.clone(),
	transaction_pool.clone(),
	prometheus_registry.as_ref(),
	telemetry.as_ref().map(|x| x.handle()),
);
let proposer_factory: PartnerChainsProposerFactory<_, _, McHashInherentDigest> =
	PartnerChainsProposerFactory::new(basic_authorship_proposer_factory);

pallet-partner-chains-session

This pallet was moved from polkadot-sdk to partner-chains, please update your cargo files.
Also add pallet-session-runtime-stub from partner-chains to your runtime dependencies.
Add pallet-session from polkadot-sdk as well to runtime and node dependencies.

runtime code

It is required to add pallet-session Runtime configuration to your construct_runtime! macro.
What is more, currently it has to be stubbed implementation, because of how pallet-partner-chains-session is implemented and wired in.
To obtain this stub implementation use:

pallet_session_runtime_stub::impl_pallet_session_config!(Runtime);

Then add: PolkadotSession:pallet_session in the construct_runtime! macro.

Increase the spec_version, so it will be possible to upgrade the runtime.

sc-cli

Runner has been reverted to pairtytech version, this requires changes in the node code,
because the vanilla polkadot-sdk version doesn't support async in a way our custom code did.

Required change is in service.rs file, where the main chain follower has to be created in a blocking way:

let data_sources = task::block_in_place(|| {
	config.tokio_handle.block_on(
		crate::main_chain_follower::create_cached_main_chain_follower_data_sources(
			mc_follower_metrics.clone(),
		),
	)
})?;

pub fn new_partial is not async anymore, please follow the change in your implementation.

Please remove async move and .await in the run function of your node in places where compiler complains.
For example replace:

Some(Subcommand::CheckBlock(cmd)) => {
	let runner = cli.create_runner(cmd)?;
	runner.async_run(|config| async move {
		let PartialComponents { client, task_manager, import_queue, .. } =
			service::new_partial(&config).await?;
		Ok((cmd.run(client, import_queue), task_manager))
	})
},

with:

Some(Subcommand::CheckBlock(cmd)) => {
	let runner = cli.create_runner(cmd)?;
	runner.async_run(|config| {
		let PartialComponents { client, task_manager, import_queue, .. } =
			service::new_partial(&config)?;
		Ok((cmd.run(client, import_queue), task_manager))
	})
},

chain-init feature

Code that was present in node crate related to USE_CHAIN_INIT feature has been removed.
The only supported way to obtain the chain-spec is through partner-chains-cli.
Please cleanup your node if it contained copy-pasted code for it.

Observation of native token illiquid supply address

This feature is not complete, please do not follow changes in partner-chains reference runtime and node.
Please do not wire it in your node code nor use the "native-token" feature in the main chain follower.

Changed

• Switched to paritytech/polkadot-sdk polkadot-stable2407-2. No migration is required because of this change.
• Reverted usage of custom Runner that allowed async_run with asynchronous initializer.
  Now Runner code used is the same as in paritytech/polkadot-sdk.
  This change requires updates in node: new_partial cannot be async.
  Run command dispatch looks more like in paritytech/polkadot-sdk.
• bugfix for Mainnet compatibility in the db-sync main-chain follower. Fixes null block_no column decoding problem.
• moved out some cli related code from node crate, in order to require less copy-paste in users nodes
• moved pallet-partner-chains-session from polkadot-sdk fork to this repository. Node uses vanilla grandpa and aura consensus now. No migration is needed.
• moved sc-consensus-aura from input-output-hk/polkadot-sdk fork to this repository,
  to sc-partner-chains-consensus-aura and sp-partner-chains-consensus-aura.
  This change requires migration of the node, PartnerChainsProposerFactory has to be used.
  See service.rs in partner-chains-node crate for an example.
• renamed sidechain-main-cli and relevant naming to pc-contracts-cli

Removed

• removed USE_CHAIN_INIT code. Migration strategy is to remove copy-pasted and adapted code. It will not compile with vanilla polkadot-sdk, that we plan to use in future.

Fixed

• ETCM-8267 - fixed partner-chains-cli missing the native token configuration

Added

• ETCM-7811 - native token movement observability components: sp-native-token-management and
  pallet-native-token-management crates; data sources behind the native-token feature in
  main-chain-follower-api and db-sync-follower crates.
• added helper functions to SidechainParams and all MainChainScripts types to read them from environment
• Extrinsic set_main_chain_scripts for migrating to new committee selection main chain scripts

Notes

• This release includes a change that requires a chain reset. Future releases will include instructions on how to upgrade the chain without reset
