Schedule (#3021)
Printing the `Schedule` is a useful debugging tool and general sanity
check. It is much more easy to interpret than the raw weights.
The printing relied on using `println` and hence was only available from
the native runtime. This is no longer available. This is why in this PR
we switch to using `log` which works from Wasm.
I made sure that the `WeightDebug` is only derived when
`runtime-benchmarks` is set so that we don't increase the size of the
binary.
Some other changes were necessary to make this actually work inside the
runtime. For example, I needed to remove `format!` and usage of floats.
Please note that this removed the decimal from the number because
truncating the fraction without using floats would not be easy and would
require custom code. I think the precision here is sufficient.
This is how the output looks like now:

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.
Releases
Note
Our release process is still Work-In-Progress and may not yet reflect the aspired outline here.
The Polkadot-SDK has two release channels: stable and nightly. Production software is advised to only use stable.
nightly is meant for tinkerers to try out the latest features. The detailed release process is described in
RELEASE.md.
Stable
stable releases have a support duration of three months. In this period, the release will not have any breaking
changes. It will receive bug fixes, security fixes, performance fixes and new non-breaking features on a two week
cadence.
Nightly
nightly releases are released every night from the master branch, potentially with breaking changes. They have
pre-release version numbers in the format major.0.0-nightlyYYMMDD.
Upstream Dependencies
Below are the primary upstream dependencies utilized in this project:
Security
The security policy and procedures can be found in docs/contributor/SECURITY.md.
