This Pull Request updates the Substrate Recipes to use the published Substrate 3.0 crates along with other ecosystem updates such as parity-scale-codec, substrate-wasm-builder, and substrate-fixed.

All code is compiling and passing tests locally. We just have to get CI sorted out. Thanks @jimmychu0807 and @sacha-l for the help.

Checklist:

• [x] Make all pallets compile
• [x] Make all runtimes compile
• [x] Make all nodes compile
• [x] Make all tests pass
• [x] General code quality review and cleanup
• [x] Fix links
• [x] Update writeups

Hello,

I see that all the recipes still using frame v1, so I thought I could upgrade some of them to frame v2. The only issue that I have is when I import a pallet with v2 into kitchen-node I have these conflicts: Any idea why it happens? What should I upgrade?

Hi everyone, after successfully compiling the node, i started it but it cannot mine new Blocks, it prepared an new Block but never imported it, any idea how to further debug that issue?!

Node Name: basic-pow Node Version: 3.0.0 Commit: commit 53f7ce1b17c7c66ebe04d5a57502d2b6e59fe48a (HEAD -> master, origin/master, origin/HEAD) Author: Joshy Orndorff [email protected] Date: Wed Apr 14 23:53:04 2021 -0400

Cargo Version: cargo 1.49.0-nightly (dd83ae55c 2020-10-20) Rustup: rustc 1.49.0-nightly (ffa2e7ae8 2020-10-24) OS: Ubuntu 20.04.2 LTS

I know that to make the pallet account works, it must have minimum_balance currency which in my point is ensured by add_extra_genesis in

decl_storage! {
	trait Store for Module<T: Trait> as SimpleTreasury {
		// No storage items of our own, but we still need decl_storage to initialize the pot
	}
	add_extra_genesis {
		build(|_config| {
			// Create the charity's pot of funds, and ensure it has the minimum required deposit
			let _ = T::Currency::make_free_balance_be(
				&<Module<T>>::account_id(),
				T::Currency::minimum_balance(),
			);
		});
	}
}

when I call donate method to donate 499 femto, it fails of transfer currency. But when I donate 500 femto, it success. I think it's affected by pub const ExistentialDeposit: u128 = 500;. But if add_extra_genesis works, the pallet account should have minimum_balance before I send the donate transaction. I am not sure this is the correct behavior or not? If it is, then why should it fail? Am I miss something.

When following the tutorial here https://substrate.dev/docs/en/tutorials/start-a-private-network/customchain, I successfully get two nodes up and running and talking to each-other in mining mode, then proceed to try and turn on GRANDPA voting.

The documents specify that I should connect to a node and call author with keyType gran and enter the mnemonic and the public key generated by subkey; once those calls are in, I should restart the nodes and they will begin to function as finalizing nodes.

This doesn't seem to work; instead, I get:

How do I debug this?

Just tried following instructions to run a kitchen node. https://substrate.dev/recipes/base/runnode.html

However seem to get the following error when running cargo build --release

Error:

araa@MAC127 ~/Desktop/recipes/kitchen/node (master) (₿) cargo build --release
    Updating git repository `https://github.com/paritytech/substrate.git`
    Updating crates.io index
error: no matching package named `srml-babe` found
location searched: https://github.com/paritytech/substrate.git
required by package `super-runtime v2.0.0 (/Users/araa/Desktop/recipes/kitchen/runtimes/super-runtime)`
    ... which is depended on by `kitchen-node v2.0.0 (/Users/araa/Desktop/recipes/kitchen/node)`

This is a draft of getting CI to check each module. My approach so far is adding a line in the .circleci/config.yml for each module. This has a significant disadvantage that the builds don't share a common target directory so the common stuff gets recompiled every time. I think the solution involves workspaces. Check out how the main substrate repo organizes all those modules into the srml directory. But I'm not sure how to do that.

I'd also like to get the cacheing working so the CI doesn't have to download so much stuff each time. @jimmychu0807 I know you took care of the caching on the front end template. Any advice to share?

Tried on the following pages:

• https://substrate.dev/recipes/storage-maps.html
• https://substrate.dev/recipes/events.html
• https://substrate.dev/recipes/cache.html

Clicking on the "Playground Try It" button returns me the following message:

I just did a fresh clone of the 'master' branch of this repo and got the following error when i ran cargo build --release. I haven't investigated why yet, but just thought I'd report it. rustc 1.52.0-nightly (35dbef235 2021-03-02)

  error: aborting due to 3 previous errors

In https://github.com/substrate-developer-hub/recipes/pull/305/commits/062d8f74a3e8bf5c5d3b7b1294488272c58a1849 I added several warning suppression lines. They were necessary due to the implementation of impl_runtime_apis! and decl_runtime_apis!. This has now been fixed upstream in Substrate https://github.com/paritytech/substrate/pull/6540

Next time we update to a more recent Substrate, these lines should be removed.

Hello,

May you already know (at least you have seen my name on PR and issues) me. Something that I do not understand why it takes 4-5 days to have a single response from you guys. I like to contribute to this repo but the responses's delay is making everything slower. I would really appreciate it if you do something about this.

I just found that the book is not updated as per FRAME v2.

So, I shall be working on this as I make my learning.

For any suggestion, please reach out to me.

My current substrate node version is 4.0.0-dev. And I am going to add offchain worker function on my current node project. I have added the ocw-demo pallet on pallets folder. And then, when I run the cargo check , I am getting this error.

How can I solve this problem? Where can I find the exact version of ocw-demo pallet for substrate version "4.0.0-dev"? Please help me!!!

Bumps thread_local from 1.1.3 to 1.1.4.

Dependabot will resolve any conflicts with this PR as long as you don't alter it yourself. You can also trigger a rebase manually by commenting @dependabot rebase.

How do I fix this error?
