feat: ⏫ upgrade to Polkadot SDK v1.11.0

[TDemeco]

Update from Polkadot SDK 1.10.0 to 1.11.0

• Changelog for Node Dev:

  • #4027 - Add candidates_pending_availability runtime API, which returns all the candidates for a parachain at a given relay block number (useful for elastic scaling)
  • #3979 - Deprecate para_id() from CoreState in polkadot primitives in favor of direct usage of ClaimQueue (which provides a better view of what’s scheduled on each core). Again, useful to know for elastic scaling
  • #4169 - transactionBroadcast RPC has been stabilized to version 1 and is no longer unstable. Useful RPC to broadcast and stop broadcasting tx to the chain. Not to be confused with tokyo’s broadcast
  • #4171 - transactionWatch RPC has been stabilized to version 1. Useful RPC to submit an extrinsic and watch its status using TransactionEvents
  • #3512
    • Issue #3045: Runtime Omni Bencher - introduces a new binary crate frame-omni-bencher that allows to directly benchmark a WASM blob without needing a node or chain spec, making it easier to generate pallet weights. It works for all FRAME runtimes that don’t have 3rd party host calls (we don’t) or non BlakeTwo256 block hashing (we do) so it should work for us. It is backwards compatible with the old CLI args too.
    • Issue #2664: Build benchmark genesis state in the runtime - Adds —runtime and —genesis-builder=none|runtime|spec arguments to the benchmark pallet command
    • Simpler args for PalletCmd::run: run() is deprecated, we either remove all benchmark code from the Node and use the new omni-bencher or change it for run_with_spec().
      • Note: changed runtime to use run_with_spec temporarily, although when we start benchmarking we should remove all benchmarking code from the node and use the omni-bencher as recommended.
  • #4168 - chainHead RPC has been stabilized to version 1. Useful RPC to track the state of the head of the chain (finallized, non-finalized, best blocks), also to get those blocks’ bodies (txs), headers, read storage entries and call runtime APIs at a specified block’s state.
  • #2714 - Added GenesisConfig presets for runtimes (e.g. local, staging, etc). To use them, the ChainSpecBuilder is extended with the with_genesis_config_preset_name method.
    • Note: the GenesisBuilder API changed to make use of these presets, I already updated it on our runtime but we don’t have any presets yet, it’s worth exploring if we could make good use of them. Usage example for Rococo here
  • #2944 - litep2p integrated into Polkadot SDK improving performance but not fully replacing rust-libp2p yet.
    • Note: Generalized everything over the new NetworkBackend type, which can be good old libp2p or new flashy litep2p. Took a while 😮‍💨
    • Note: maybe it’s worth taking a more in-depth look at this since we rely on p2p comms as well?
  • #3801 - Removed slot_duration from aura::collators::basic::Params, it now has to be fetched using Aura’s runtime API
    • Note: change done in node/src/service.rs + removed unneeded code from node/src/command.rs (logging parachain account)

• Changelog for Runtime Dev:

  • #3485 - Adds runtime API for pallet-broker to get the current price of a core in the ongoing sale
  • #3708 - QoL improvement for the XCM builder pattern: no longer are the .into() needed when constructing messages, it automatically converts the instruction parameters
    • Note: no changes needed since we don’t currently use the builder pattern for XCM, but good to know.
  • #2119 - Adds example pallet for Multi-Block-Migrations under frame/examples and MigrationId to frame-support
    • Note: not useful right now but useful if we ever need to do a MBM
  • #2292 - Migrate fee payment from Currency to Fungible
    • Note: updated runtime with FungibleAdapter and file-system pallet since it was using the to-be-deprecated Currency trait
  • #4006 - Fix dynamic_params name expand on pallet-parameters
    • Note: @ffarall tagging you just in case you have to modify anything on the parameters pallet
  • #4075 - Adds ability to trigger tasks via unsigned transactions.
    • validate_unsigned hook for frame-system allows valid tasks to be submitted as unsigned transactions
    • The is_valid call on a task is the one that validates if the task is valid to be submitted as an unsigned transaction. As such, to prevent DoS attacks, it has to be cheap with minimal to no storage reads.
    • The unsigned tasks will be executed in a random order
    • Example in substrate/frame/examples/tasks/
    • Note: super useful for offchain workers! It might help us
  • #4156 - Adds AllowHrmpNotificationsFromRelayChain barrier for safety (to ensure HRMP notifications originate solely from the Relay Chain)
    • Note: implemented in both the xcm-simulator and the actual runtime.
  • #3721 - Adds hrmp.establish_channel_with_system call to allow parachains to establish a channel with a system parachain
  • #4017 - Remove TryRuntime subcommand from node (we should use the standalone CLI https://github.com/paritytech/try-runtime-cli)
  • #4266 - Reverts #3749, removing execute_blob and send_blob and restoring execute and send

• Extra changes:

  • #4605 - Backport litep2p, locking it to 0.5.0 (since at release it was locked at the master branch which resulted in StorageHub not compiling because of the changes done since then to litep2p)
  • #4584 - Backport CheckMetadataHash extension according to RFC 0078 (also check #4274)

All looks good, just wanted to clarify the use of having both rust-libp2p and litep2p network backends.

Again, outstanding PR docs.
