chore(deps): migrate subxt from v0.44 to v0.50#1229
Merged
Conversation
Complete the API migration across toolkit, upgrader, relay, e2e tests, and scripts for the subxt v0.50 rewrite. Key changes: - Block-centric API: api.blocks().at() → api.at_block(), api.storage().at_latest() → api.at_current_block().storage() - Transaction types: TxProgress → TransactionProgress, TxInBlock → TransactionInBlock, TxStatus → TransactionStatus - api.tx() is now async, encode_call_data() → tx().call_data() - api.metadata() removed from OnlineClient; use at_current_block().metadata_ref() - Metadata no longer Clone; use ArcMetadata (Arc<Metadata>) for shared ownership - Granular error types: OnlineClientAtBlockError, ExtrinsicError, RuntimeApiError, etc. - Event API: variant_name() → event_name(), as_event() → decode_fields_as(), field_values() removed - Storage API: key now passed to fetch(addr, key) instead of address constructor - Block from streams: extrinsics/events accessed via block.at().await? first - dynamic::tx().into_value() requires Composite::unnamed() instead of Vec - RpcConfig trait impl required for LegacyRpcMethods
2 tasks
Share the RPC WebSocket connection within each client, cap fetch workers to actual workload size, and retry transient transport errors during transaction submission with exponential backoff.
