Bastian Köcher a33d7922f8 Rename polkadot-parachain to polkadot-parachain-primitives (#1334 )

* Rename `polkadot-parachain` to `polkadot-parachain-primitives`

While doing this it also fixes some last `rustdoc` issues and fixes
another Cargo warning related to `pallet-paged-list`.

* Fix compilation

* ".git/.scripts/commands/fmt/fmt.sh"

* Fix XCM docs

Bridge-hub Parachains

Bridge-hub Parachains

BridgeHub(s) are system parachains that will house trustless bridges from the local ecosystem to others. The current trustless bridges planned for the BridgeHub(s) are:

BridgeHubPolkadot system parachain:
1. Polkadot <-> Kusama bridge
2. Polkadot <-> Ethereum bridge (Snowbridge)
BridgeHubKusama system parachain:
1. Kusama <-> Polkadot bridge
2. Kusama <-> Ethereum bridge The high-level responsibilities of each bridge living on BridgeHub:
sync finality proofs between relay chains (or equivalent)
sync finality proofs between BridgeHub parachains
pass (XCM) messages between different BridgeHub parachains

Requirements for local run/testing

# Prepare empty directory for testing
mkdir -p ~/local_bridge_testing/bin
mkdir -p ~/local_bridge_testing/logs

---
# 1. Install zombienet
Go to: https://github.com/paritytech/zombienet/releases
Copy the apropriate binary (zombienet-linux) from the latest release to ~/local_bridge_testing/bin


---
# 2. Build polkadot binary
git clone https://github.com/paritytech/polkadot.git
cd polkadot

# if you want to test Kusama/Polkadot bridge, we need "sudo pallet + fast-runtime",
# so please, find the latest polkadot's repository branch `it/release-vX.Y.Z-fast-sudo`
# e.g:
# git checkout -b it/release-v0.9.43-fast-sudo --track origin/it/release-v0.9.43-fast-sudo

cargo build --release --features fast-runtime
cp target/release/polkadot ~/local_bridge_testing/bin/polkadot


---
# 3. Build substrate-relay binary
git clone https://github.com/paritytech/parity-bridges-common.git
cd parity-bridges-common

# checkout desired branch or use master:
# git checkout -b master --track origin/master
# `polkadot-staging` (recommended) is stabilized and compatible for Cumulus releases
# `master` is latest development
git checkout -b polkadot-staging --track origin/polkadot-staging

cargo build --release -p substrate-relay
cp target/release/substrate-relay ~/local_bridge_testing/bin/substrate-relay


---
# 4. Build cumulus polkadot-parachain binary
cd <cumulus-git-repo-dir>

# checkout desired branch or use master:
# git checkout -b master --track origin/master

cargo build --release --locked --bin polkadot-parachain
cp target/release/polkadot-parachain ~/local_bridge_testing/bin/polkadot-parachain
cp target/release/polkadot-parachain ~/local_bridge_testing/bin/polkadot-parachain-asset-hub



# !!! READ HERE (TODO remove once all mentioned branches bellow are merged)
# The use case "moving assets over bridge" is not merged yet and is implemented in separate branches.
# So, if you want to try it, you need to checkout different branch and continue with these instructions there.

# For Kusama/Polkadot local bridge testing:
#
# build BridgeHubs (polkadot-parachain) from branch:
# git checkout -b bridge-hub-kusama-polkadot --track origin/bridge-hub-kusama-polkadot
# cargo build --release --locked --bin polkadot-parachain
# cp target/release/polkadot-parachain ~/local_bridge_testing/bin/polkadot-parachain
#
# build AssetHubs (polkadot-parachain-asset-hub) from branch:
# git checkout -b bko-transfer-asset-via-bridge-pallet-xcm --track origin/bko-transfer-asset-via-bridge-pallet-xcm
# cargo build --release --locked --bin polkadot-parachain
# cp target/release/polkadot-parachain ~/local_bridge_testing/bin/polkadot-parachain-asset-hub

# For Rococo/Wococo local bridge testing:
#
# build AssetHubs (polkadot-parachain-asset-hub) from branch:
# git checkout -b bko-transfer-asset-via-bridge-pallet-xcm-ro-wo --track origin/bko-transfer-asset-via-bridge-pallet-xcm-ro-wo
# cargo build --release --locked --bin polkadot-parachain
# cp target/release/polkadot-parachain ~/local_bridge_testing/bin/polkadot-parachain-asset-hub

How to test local Rococo <-> Wococo bridge

Run chains (Rococo + BridgeHub + AssetHub, Wococo + BridgeHub + AssetHub) with zombienet

# Rococo + BridgeHubRococo + AssetHub for Rococo (mirroring Kusama)
POLKADOT_BINARY_PATH=~/local_bridge_testing/bin/polkadot \

	~/local_bridge_testing/bin/zombienet-linux --provider native spawn ./zombienet/bridge-hubs/bridge_hub_rococo_local_network.toml

	~/local_bridge_testing/bin/zombienet-linux --provider native spawn ./zombienet/bridge-hubs/bridge_hub_wococo_local_network.toml

Run relayer (BridgeHubRococo, BridgeHubWococo)

Accounts of BridgeHub parachains:

Bob is pallet owner of all bridge pallets

Run with script (alternative 1)

cd <cumulus-git-repo-dir>
./scripts/bridges_rococo_wococo.sh run-relay

Run with binary (alternative 2)

Need to wait for parachain activation (start producing blocks), then run:

# 1. Init bridges:

# Rococo -> Wococo

	~/local_bridge_testing/bin/substrate-relay init-bridge rococo-to-bridge-hub-wococo \

	--source-version-mode Auto \
	--target-host localhost \
	--target-port 8945 \
	--target-version-mode Auto \
	--target-signer //Bob

# Wococo -> Rococo
RUST_LOG=runtime=trace,rpc=trace,bridge=trace \
	~/local_bridge_testing/bin/substrate-relay init-bridge wococo-to-bridge-hub-rococo \
