When launching our [small network](https://github.com/paritytech/polkadot-sdk/blob/master/cumulus/zombienet/examples/small_network.toml) for testing the node was crashing here shortly after launch: https://github.com/paritytech/polkadot-sdk/blob/5cdd819ed295645958afd9d937d989978fd0c84e/polkadot/node/collation-generation/src/lib.rs#L140 After changes in #1788 for the asset hub collator we are waiting for blocks of the shell runtime to pass before we initialize aura. However, this means that we attempted to initialize the collation related relay chain subsystems twice, leading to the error. I modified Aura to let it optionally take an already initialized stream of collation requests.
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.
