Closes #2326. This PR both fixes a logic bug and replaces an incorrect name. ## Bug Fix: Respecting custom genesis builder Prior to this PR the standard logic for creating a genesis block was repeated inside of cumulus. This PR removes that duplicated logic, and calls into the proper `BuildGenesisBlock` implementation. One consequence is that if the genesis block has already been initialized, it will not be re-created, but rather read from the database like it is for other node invocations. So you need to watch out for old unpurged data during the development process. Offchain tools may need to be updated accordingly. I've already filed https://github.com/paritytech/zombienet/issues/1519 ## Rename: It doesn't export state. It exports head data. The name export-genesis-state was always wrong, nad it's never too late to right a wrong. I've changed the name of the struct to `ExportGenesisHeadCommand`. There is still the question of what to do with individual nodes' public CLIs. I have updated the parachain template to a reasonable default that preserves compatibility with tools that will expect `export-genesis-state` to still work. And I've chosen not to modify the public CLIs of any other nodes in the repo. I'll leave it up to their individual owners/maintains to decide whether that is appropriate. --------- Co-authored-by: Joshy Orndorff <git-user-email.h0ly5@simplelogin.com> Co-authored-by: Bastian Köcher <git@kchr.de> Co-authored-by: Bastian Köcher <info@kchr.de>
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.
