This PR backports the error codes from the spec. This relies on two specs for defining the error codes: - Our rpc-spec-v2 https://github.com/paritytech/json-rpc-interface-spec. - JSON-RPC spec https://www.jsonrpc.org/specification#error_object. To better describe the error codes, they are divided into two separate modules `rpc_spec_v2` and `json_rpc_spec` respectively. The `InvalidSubscriptionID` and `FetchBlockHeader` are merged into the JSON-RPC spec `INTERNAL_ERROR`. While the other error codes are adjusted from spec. Errors that are currently in use: - -32801 block hash not reported by chainHead_follow or block hash has been unpinned - -32802 chainHead_follow started with withRuntime == false - -32803 chainHead_follow did not generate an operationWaitingForContinue event The following are errors defined in the [JSON-RPC spec](https://www.jsonrpc.org/specification#error_object): - -32602 The provided parameter isn't one of the expected values, has different format or is missing - -32603 Internal server error Note: Error `-32801` must be introduced and generated by the outstanding https://github.com/paritytech/polkadot-sdk/issues/1505 Closes: https://github.com/paritytech/polkadot-sdk/issues/2530 --------- Signed-off-by: Alexandru Vasile <alexandru.vasile@parity.io>
NOTE: We have recently made significant changes to our repository structure. In order to streamline our development process and foster better contributions, we have merged three separate repositories Cumulus, Substrate and Polkadot into this repository. Read more about the changes here.
Polkadot SDK
The Polkadot SDK repository provides all the resources needed to start building on the Polkadot network, a multi-chain blockchain platform that enables different blockchains to interoperate and share information in a secure and scalable way. The Polkadot SDK comprises three main pieces of software:
Polkadot
Implementation of a node for the https://polkadot.network in Rust, using the Substrate framework. This directory
currently contains runtimes for the Polkadot, Kusama, Westend, and Rococo networks. In the future, these will be
relocated to the runtimes repository.
Substrate
Substrate is the primary blockchain SDK used by developers to create the parachains that make up the Polkadot network. Additionally, it allows for the development of self-sovereign blockchains that operate completely independently of Polkadot.
Cumulus
Cumulus is a set of tools for writing Substrate-based Polkadot parachains.
