Subject: [PATCH 003/106] make polkadot-parachain chain-spec extension more
 relaxed (#4452)

A small step towards
https://forum.polkadot.network/t/polkadot-parachain-omni-node-gathering-ideas-and-feedback/7823
and #4352.

Many parachains use `camelCase` and/or `PascalCase`ing for their chain
spec extension. Sometimes the only reason polkadot-parachain cannot sync
them is because it cannot parse the chain spec extension. This PR
relaxes the requirement for the extension to be camel case.

Subject: [PATCH 004/106] Change forks pruning algorithm. (#3962)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This PR changes the fork calculation and pruning algorithm to enable
future block header pruning. It's required because the previous
algorithm relied on the block header persistence. It follows the
[related
discussion](https://github.com/paritytech/polkadot-sdk/issues/1570)

The previous code contained this comment describing the situation:
```
	/// Note a block height finalized, displacing all leaves with number less than the finalized
	/// block's.
	///
	/// Although it would be more technically correct to also prune out leaves at the
	/// same number as the finalized block, but with different hashes, the current behavior
	/// is simpler and our assumptions about how finalization works means that those leaves
	/// will be pruned soon afterwards anyway.
	pub fn finalize_height(&mut self, number: N) -> FinalizationOutcome<H, N> {
```

The previous algorithm relied on the existing block headers to prune
forks later and to enable block header pruning we need to clear all
obsolete forks right after the block finalization to not depend on the
related block headers in the future.

Subject: [PATCH 009/106] Introduces: Delegated Staking Pallet (#3904)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This is the second PR in preparation for
https://github.com/paritytech/polkadot-sdk/issues/454.

## Also see
- **Precursor** https://github.com/paritytech/polkadot-sdk/pull/3889.
- **Follow up** https://github.com/paritytech/polkadot-sdk/pull/3905.

Overall changes are documented here (lot more visual 😍):
https://hackmd.io/@ak0n/454-np-governance

## Changes
### Delegation Interface
Provides delegation primitives for staking.

Introduces two new roles:
- Agent: These are accounts who receive delegation from other accounts
(delegators) and stakes on behalf of them. The funds are held in
delegator accounts.
- Delegator: Accounts who delegate their funds to an agent authorising
them to use it for staking.

Supports
- A way for delegators to add or withdraw delegation to an agent.
- A way for an agent to slash a delegator during a slashing event.

### Pallet Delegated Staking
- Implements `DelegationInterface`.
- Lazy slashing: Any slashes to an Agent is posted in a ledger but not
immediately slashed. The agent can call
`DelegationInterface::delegator_slash` to slash the member and clear the
corresponding slash from its ledger.
- Consumes `StakingInterface` to provide `CoreStaking` features. In
reality, this will be `pallet-staking`.
- Ensures bookkeeping for agent and delegator are correct but leaves the
management of reward and slash logic upto the consumer of this pallet.
- While it does not expose any calls yet, it is written with the intent
of exposing these primitives via extrinsics.

## TODO
- [x] Improve unit tests in the pallet.
- [x] Separate slash reward perbill for rewarding the slash reporters?
- [x] Review if we should add more events.

+//! # Delegated Staking Pallet
+//!
+//! This pallet implements [`sp_staking::DelegationInterface`] that provides delegation
+//! functionality to `delegators` and `agents`. It is designed to be used in conjunction with
+//! [`StakingInterface`] and relies on [`Config::CoreStaking`] to provide primitive staking
+//! functions.
+//!
+//! Currently, it does not expose any dispatchable calls but is written with a vision to expose them
+//! in the future such that it can be utilised by any external account, off-chain entity or xcm
+//! `MultiLocation` such as a parachain or a smart contract.
+//!
+//! ## Key Terminologies
+//! - **Agent**: An account who accepts delegations from other accounts and act as an agent on their
+//!   behalf for staking these delegated funds. Also, sometimes referred as `Delegatee`.
+//! - **Delegator**: An account who delegates their funds to an `agent` and authorises them to use
+//!   it for staking.
+//! - **AgentLedger**: A data structure that holds important information about the `agent` such as
+//!   total delegations they have received, any slashes posted to them, etc.
+//! - **Delegation**: A data structure that stores the amount of funds delegated to an `agent` by a
+//!   `delegator`.
+//!
+//! ## Goals
+//!
+//! Direct nomination on the Staking pallet does not scale well. Nominations pools were created to
+//! address this by pooling delegator funds into one account and then staking it. This though had
+//! a very critical limitation that the funds were moved from delegator account to pool account
+//! and hence the delegator lost control over their funds for using it for other purposes such as
+//! governance. This pallet aims to solve this by extending the staking pallet to support a new
+//! primitive function: delegation of funds to an `agent` with the intent of staking. The agent can
+//! then stake the delegated funds to [`Config::CoreStaking`] on behalf of the delegators.
+//!
+//! ### Withdrawal Management
+//! Agent unbonding does not regulate ordering of consequent withdrawal for delegators. This is upto
+//! the consumer of this pallet to implement in what order unbondable funds from
+//! [`Config::CoreStaking`] can be withdrawn by the delegators.
+//!
+//! ### Reward and Slashing
+//! This pallet does not enforce any specific strategy for how rewards or slashes are applied. It
+//! is upto the `agent` account to decide how to apply the rewards and slashes.
+//!
+//! This importantly allows clients of this pallet to build their own strategies for reward/slashes.
+//! For example, an `agent` account can choose to first slash the reward pot before slashing the
+//! delegators. Or part of the reward can go to an insurance fund that can be used to cover any
+//! potential future slashes. The goal is to eventually allow foreign MultiLocations
+//! (smart contracts or pallets on another chain) to build their own pooled staking solutions
+//! similar to `NominationPools`.
+
+//! ## Core functions
+//!
+//! - Allow an account to receive delegations. See [`Pallet::register_agent`].
+//! - Delegate funds to an `agent` account. See [`Pallet::delegate_to_agent`].
+//! - Release delegated funds from an `agent` account to the `delegator`. See
+//!   [`Pallet::release_delegation`].
+//! - Migrate a `Nominator` account to an `agent` account. See [`Pallet::migrate_to_agent`].
+//!   Explained in more detail in the `Migration` section.
+//! - Migrate unclaimed delegated funds from `agent` to delegator. When a nominator migrates to an
+//! agent, the funds are held in a proxy account. This function allows the delegator to claim their
+//! share of the funds from the proxy account. See [`Pallet::migrate_delegation`].
+//!
+//! ## Lazy Slashing
+//! One of the reasons why direct nominators on staking pallet cannot scale well is because all
+//! nominators are slashed at the same time. This is expensive and needs to be bounded operation.
+//!
+//! This pallet implements a lazy slashing mechanism. Any slashes to the `agent` are posted in its
+//! `AgentLedger` as a pending slash. Since the actual amount is held in the multiple
+//! `delegator` accounts, this pallet has no way to know how to apply slash. It is the `agent`'s
+//! responsibility to apply slashes for each delegator, one at a time. Staking pallet ensures the
+//! pending slash never exceeds staked amount and would freeze further withdraws until all pending
+//! slashes are cleared.
+//!
+//! The user of this pallet can apply slash using
+//! [DelegationInterface::delegator_slash](sp_staking::DelegationInterface::delegator_slash).
+//!
+//! ## Migration from Nominator to Agent
+//! More details [here](https://hackmd.io/@ak0n/454-np-governance).
+//!
+//! ## Nomination Pool vs Delegation Staking
+//! This pallet is not a replacement for Nomination Pool but adds a new primitive in addition to
+//! staking pallet that can be used by Nomination Pool to support delegation based staking. It can
+//! be thought of as an extension to the Staking Pallet in relation to Nomination Pools.
+//! Technically, these changes could be made in one of those pallets as well but that would have
+//! meant significant refactoring and high chances of introducing a regression. With this approach,
+//! we can keep the existing pallets with minimal changes and introduce a new pallet that can be
+//! optionally used by Nomination Pool. The vision is to build this in a configurable way such that
+//! runtime can choose whether to use this pallet or not.
+//!
+//! With that said, following is the main difference between
+//! #### Nomination Pool without delegation support
+//!  1) transfer fund from delegator to pool account, and
+//!  2) stake from pool account as a direct nominator.
+//!
+//! #### Nomination Pool with delegation support
+//!  1) delegate fund from delegator to pool account, and
+//!  2) stake from pool account as an `Agent` account on the staking pallet.
+//!
+//! The difference being, in the second approach, the delegated funds will be locked in-place in
+//! user's account enabling them to participate in use cases that allows use of `held` funds such
+//! as participation in governance voting.
+//!
+//! Nomination pool still does all the heavy lifting around pool administration, reward
+//! distribution, lazy slashing and as such, is not meant to be replaced with this pallet.
+//!
+//! ## Limitations
+//! - Rewards can not be auto-compounded.
+//! - Slashes are lazy and hence there could be a period of time when an account can use funds for
+//!   operations such as voting in governance even though they should be slashed.

Subject: [PATCH 011/106] Fix extrinsics count logging in frame-system (#4461)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The storage item ExtrinsicIndex is already taken before the `finalize()`
in `note_finished_extrinsics()`, rendering it's always 0 in the log.
This commit fixes it by using the proper API for extrinsics count.

Subject: [PATCH 013/106] Make vscode rustanalyzer fast again (#4470)

This bump of versions:

https://github.com/paritytech/polkadot-sdk/pull/4409/files#diff-13ee4b2252c9e516a0547f2891aa2105c3ca71c6d7a1e682c69be97998dfc87eR11936

reintroduced a dependency to proc-macro-crate 2.0.0 which is suffering
from: https://github.com/bkchr/proc-macro-crate/pull/42 this, so bump
parity-scale-codec to a newer version to eliminate the bad
proc-macro-crate 2.0.0 dependency.

Subject: [PATCH 016/106] Add IBP bootnodes to `coretime-westend` and
 `coretime-kusama` and others (#4276)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Dear team, hello,

Please consider this request to add bootnode endpoints to the chainspecs
of `coretime-westend` and `coretime-kusama`.

These bootnodes are operated by the Infrastructure Builders Programme as
part of the commitments of their members.

All these endpoints have been tested according to the procedure
indicated
[here](https://wiki.ibp.network/docs/consumers/bootnodes#testing-a-bootnode).

Additionally, please also consider some maintenance changes to
Gatotech's bootnode endpoint in several other chains.

Many thanks!!

Best regrds!

**_Milos_**

From 289f5bbf7a45dc0380904a435464b15ec711ed03 Mon Sep 17 00:00:00 2001
From: Francisco Aguirre <franciscoaguirreperez@gmail.com>

Subject: [PATCH 017/106] XCM Cookbook (#2633)

# Context

XCM docs are currently an md book hosted with github pages:
https://paritytech.github.io/xcm-docs/.
While that's fine, it's not in line with the work being done in the
polkadot-sdk docs.

# Main addition

This PR aims to fix that by bringing the docs back to this repo.
This does not have all the information currently present in the mdbook
xcm-docs but aims to be a good chunk of it and fully replace it over
time.

I also added the sections `guides` and `cookbook` which will be very
useful for users wanting to get into XCM.
For now I only added one example to the cookbook, but have ideas for
guides and more examples.
Having this docs be in rust docs is very useful for the cookbook.

# TODO

- [x] Use `FungibleAdapter`
- [x] Improve and relocate mock message queue
- [x] Fix license issue. Why does docs/sdk/ not have this problem? (Just
added the licenses)

# Next steps

- More examples in the cookbook
- End-to-end XCM guide with zombienet testing

+//! # Relay Asset Transactor
+//!
+//! This example shows how to configure a parachain to only deal with the Relay Chain token.
+//!
+//! The first step is using the [`xcm_builder::FungibleAdapter`] to create an `AssetTransactor` that
+//! can handle the relay chain token.
+#![doc = docify::embed!("src/cookbook/relay_token_transactor/parachain/xcm_config.rs", asset_transactor)]
+//!
+//! The second step is to configure `IsReserve` to recognize the relay chain as a reserve for its
+//! own asset.
+//! With this, you'll be able to easily mint a derivative asset, backed one-to-one from the Relay
+//! Chain, by using the xcm pallet's `transfer_assets` extrinsic.
+//!
+//! The `IsReserve` type takes a type that implements `ContainsPair<MultiAsset, MultiLocation>`.
+//! In this case, we want a type that contains the pair `(relay_chain_native_token, relay_chain)`.
+#![doc = docify::embed!("src/cookbook/relay_token_transactor/parachain/xcm_config.rs", is_reserve)]
+//!
+//! With this setup, we are able to do a reserve asset transfer to and from the parachain and relay
+//! chain.
+#![doc = docify::embed!("src/cookbook/relay_token_transactor/tests.rs", reserve_asset_transfers_work)]

+//! # XCM Fundamentals
+//!
+//! XCM standardizes usual actions users take in consensus systems, for example
+//! dealing with assets locally, on other chains, and locking them.
+//! XCM programs can both be executed locally or sent to a different consensus system.
+//! Examples of consensus systems are blockchains and smart contracts.
+//!
+//! The goal of XCM is to allow multi-chain ecosystems to thrive via specialization.
+//! Very specific functionalities can be abstracted away and standardized in this common language.
+//! Then, every member of the ecosystem can implement the subset of the language that makes sense
+//! for them.
+//!
+//! The language evolves over time to accomodate the needs of the community
+//! via the [RFC process](https://github.com/paritytech/xcm-format/blob/master/proposals/0032-process.md).
+//!
+//! XCM is the language, it deals with interpreting and executing programs.
+//! It does not deal with actually **sending** these programs from one consensus system to another.
+//! This responsibility falls to a transport protocol.
+//! XCM can even be interpreted on the local system, with no need of a transport protocol.
+//! However, automatic and composable workflows can be achieved via the use of one.
+//!
+//! At the core of XCM lies the XCVM, the Cross-Consensus Virtual Machine.
+//! It's the virtual machine that executes XCM programs.
+//! It is a specification that comes with the language.
+//!
+//! For these docs, we'll use a Rust implementation of XCM and the XCVM, consisting of the following
+//! parts:
+//! - [`XCM`](xcm): Holds the definition of an XCM program, the instructions and main concepts.
+//! - [`Executor`](xcm_executor): Implements the XCVM, capable of executing XCMs. Highly
+//!   configurable.
+//! - [`Builder`](xcm_builder): A collection of types used to configure the executor.
+//! - [`XCM Pallet`](pallet_xcm): A FRAME pallet for interacting with the executor.
+//! - [`Simulator`](xcm_simulator): A playground to tinker with different XCM programs and executor
+//!   configurations.
+//!
+//! XCM programs are composed of Instructions, which reference Locations and Assets.
+//!
+//! ## Locations
+//!
+//! Locations are XCM's vocabulary of places we want to talk about in our XCM programs.
+//! They are used to reference things like 32-byte accounts, governance bodies, smart contracts,
+//! blockchains and more.
+//!
+//! Locations are hierarchical.
+//! This means some places in consensus are wholly encapsulated in other places.
+//! Say we have two systems A and B.
+//! If any change in A's state implies a change in B's state, then we say A is interior to B.
+#![doc = simple_mermaid::mermaid!("../mermaid/location_hierarchy.mmd")]
+//!
+//! Parachains are interior to their Relay Chain, since a change in their state implies a change in
+//! the Relay Chain's state.
+//!
+//! Because of this hierarchy, the way we represent locations is with both a number of **parents**,
+//! times we move __up__ the hierarchy, and a sequence of **junctions**, the steps we take __down__
+//! the hierarchy after going up the specified number of parents.
+//!
+//! In Rust, this is specified with the following datatype:
+//! ```ignore
+//! pub struct Location {
+//!   parents: u8,
+//!   interior: Junctions,
+//! }
+//! ```
+//!
+//! Many junctions are available; parachains, pallets, 32 and 20 byte accounts, governance bodies,
+//! and arbitrary indices are the most common.
+//! A full list of available junctions can be found in the [format](https://github.com/paritytech/xcm-format#interior-locations--junctions)
+//! and [Junction enum](xcm::v4::prelude::Junction).
+//!
+//! We'll use a file system notation to represent locations, and start with relative locations.
+//! In the diagram, the location of parachain 1000 as seen from all other locations is as follows:
+//! - From the relaychain: `Parachain(1000)`
+//! - From parachain 1000 itself: `Here`
+//! - From parachain 2000: `../Parachain(1000)`
+//!
+//! Relative locations are interpreted by the system that is executing an XCM program, which is the
+//! receiver of a message in the case where it's sent.
+//!
+//! Locations can also be absolute.
+//! Keeping in line with our filesystem analogy, we can imagine the root of our filesystem to exist.
+//! This would be a location with no parents, that is also the parent of all systems that derive
+//! their own consensus, say Polkadot or Ethereum or Bitcoin.
+//! Such a location does not exist concretely, but we can still use this definition for it.
+//! This is the **universal location**.
+//! We need the universal location to be able to describe locations in an absolute way.
+#![doc = simple_mermaid::mermaid!("../mermaid/universal_location.mmd")]
+//!
+//! Here, the absolute location of parachain 1000 would be
+//! `GlobalConsensus(Polkadot)/Parachain(1000)`.
+//!
+//! ## Assets
+//!
+//! We want to be able to reference assets in our XCM programs, if only to be able to pay for fees.
+//! Assets are represented using locations.
+//!
+//! The native asset of a chain is represented by the location of that chain.
+//! For example, DOT is represented by the location of the Polkadot relaychain.
+//! If the interpreting chain has its own asset, it would be represented by `Here`.
+//!
+//! How do we represent other assets?
+//! The asset hub system parachain in Polkadot, for example, holds a lot of assets.
+//! To represent each of them, it uses the indices we mentioned, and it makes them interior to the
+//! assets pallet instance it uses.
+//! USDT, an example asset that lives on asset hub, is identified by the location
+//! `Parachain(1000)/PalletInstance(53)/GeneralIndex(1984)`, when seen from the Polkadot relaychain.
+#![doc = simple_mermaid::mermaid!("../mermaid/usdt_location.mmd")]
+//!
+//! Asset Hub also has another type of assets called `ForeignAssets`.
+//! These assets are identified by the XCM Location to their origin.
+//! Two such assets are a Parachain asset, like Moonbeam's GLMR, and KSM, from the cousin Kusama
+//! network. These are represented as `../Parachain(2004)/PalletInstance(10)` and
+//! `../../GlobalConsensus(Kusama)` respectively.
+//!
+//! The whole type can be seen in the [format](https://github.com/paritytech/xcm-format#6-universal-asset-identifiers)
+//! and [rust docs](xcm::v4::prelude::Asset).
+//!
+//! ## Instructions
+//!
+//! Given the vocabulary to talk about both locations -- chains and accounts -- and assets, we now
+//! need a way to express what we want the consensus system to do when executing our programs.
+//! We need a way of writing our programs.
+//!
+//! XCM programs are composed of a sequence of instructions.
+//!
+//! All available instructions can be seen in the [format](https://github.com/paritytech/xcm-format#5-the-xcvm-instruction-set)
+//! and the [Instruction enum](xcm::v4::prelude::Instruction).
+//!
+//! A very simple example is the following:
+//!
+//! ```ignore
+//! let message = Xcm(vec![
+//!   TransferAsset { assets, beneficiary },
+//! ]);
+//! ```
+//!
+//! This instruction is enough to transfer `assets` from the account of the **origin** of a message
+//! to the `beneficiary` account. However, because of XCM's generality, fees need to be paid
+//! explicitly. This next example sheds more light on this:
+//!
+//! ```ignore
+//! let message = Xcm(vec![
+//!   WithdrawAsset(assets),
+//!   BuyExecution { fees: assets, weight_limit },
+//!   DepositAsset { assets: AssetFilter(Wild(All)), beneficiary },
+//! ]);
+//! ```
+//!
+//! Here we see the process of transferring assets was broken down into smaller instructions, and we
+//! add the explicit fee payment step in the middle.
+//! `WithdrawAsset` withdraws assets from the account of the **origin** of the message for usage
+//! inside this message's execution. `BuyExecution` explicitly buys execution for this program using
+//! the assets specified in `fees`, with a sanity check of `weight_limit`. `DepositAsset` uses a
+//! wildcard, specifying all remaining `assets` after subtracting the fees and a `beneficiary`
+//! account.
+//!
+//! ## Next steps
+//!
+//! Continue with the [guides](crate::guides) for step-by-step tutorials on XCM,
+//! or jump to the [cookbook](crate::cookbook) to see examples.
+//!
+//! The [glossary](crate::glossary) can be useful if some of the terms are confusing.

+//! # Glossary
+//!
+//! ## XCM (Cross-Consensus Messaging)
+//!
+//! A messaging format meant to communicate intentions between consensus systems.
+//! XCM could also refer to a single message.
+//!
+//! ## Instructions
+//!
+//! XCMs are composed of a sequence of instructions.
+//! Each instruction aims to convey a particular intention.
+//! There are instructions for transferring and locking assets, handling fees, calling arbitrary
+//! blobs, and more.
+//!
+//! ## Consensus system
+//!
+//! A system that can reach any kind of consensus.
+//! For example, relay chains, parachains, smart contracts.
+//! Most messaging between consensus systems has to be done asynchronously, for this, XCM is used.
+//! Between two smart contracts on the same parachain, however, communication can be done
+//! synchronously.
+//!
+//! ## [`Location`](xcm::v4::prelude::Location)
+//!
+//! A way of addressing consensus systems.
+//! These could be relative or absolute.
+//!
+//! ## [`Junction`](xcm::v4::prelude::Junction)
+//!
+//! The different ways of descending down a [`Location`](xcm::v4::prelude::Location) hierarchy.
+//! A junction can be a Parachain, an Account, or more.
+//!
+//! ## [`Asset`](xcm::v4::prelude::Asset)
+//!
+//! A way of identifying assets in the same or another consensus system, by using a
+//! [`Location`](xcm::v4::prelude::Location).
+//!
+//! ## Sovereign account
+//!
+//! An account in a consensus system that is controlled by an account in another consensus system.
+//!
+//! Runtimes use a converter between a [`Location`](xcm::v4::prelude::Location) and an account.
+//! These converters implement the [`ConvertLocation`](xcm_executor::traits::ConvertLocation) trait.
+//!
+//! ## Teleport
+//!
+//! A way of transferring assets between two consensus systems without the need of a third party.
+//! It consists of the sender system burning the asset that wants to be sent over and the recipient
+//! minting an equivalent amount of that asset. It requires a lot of trust between the two systems,
+//! since failure to mint or burn will reduce or increase the total issuance of the token.
+//!
+//! ## Reserve asset transfer
+//!
+//! A way of transferring assets between two consensus systems that don't trust each other, by using
+//! a third system they both trust, called the reserve. The real asset only exists on the reserve,
+//! both sender and recipient only deal with derivatives. It consists of the sender burning a
+//! certain amount of derivatives, telling the reserve to move real assets from its sovereign
+//! account to the destination's sovereign account, and then telling the recipient to mint the right
+//! amount of derivatives.
+//! In practice, the reserve chain can also be one of the source or destination.
+//!
+//! ## XCVM
+//!
+//! The virtual machine behind XCM.
+//! Every XCM is an XCVM programme.
+//! Holds state in registers.
+//!
+//! An implementation of the virtual machine is the [`xcm-executor`](xcm_executor::XcmExecutor).
+//!
+//! ## Holding register
+//!
+//! An XCVM register used to hold arbitrary `Asset`s during the execution of an XCVM programme.
+//!
+//! ## Barrier
+//!
+//! An XCM executor configuration item that works as a firewall for incoming XCMs.
+//! All XCMs have to pass the barrier to be executed, else they are dropped.
+//! It can be used for whitelisting only certain types or messages or messages from certain senders.
+//!
+//! Lots of barrier definitions exist in [`xcm-builder`](xcm_builder).
+//!
+//! ## VMP (Vertical Message Passing)
+//!
+//! Umbrella term for both UMP (Upward Message Passing) and DMP (Downward Message Passing).
+//!
+//! The following diagram shows the uses of both protocols:
+#![doc = simple_mermaid::mermaid!("../mermaid/transport_protocols.mmd")]
+//!
+//! ## UMP (Upward Message Passing)
+//!
+//! Transport-layer protocol that allows parachains to send messages upwards to their relay chain.
+//!
+//! ## DMP (Downward Message Passing)
+//!
+//! Transport-layer protocol that allows the relay chain to send messages downwards to one of their
+//! parachains.
+//!
+//! ## XCMP (Cross-Consensus Message Passing)
+//!
+//! Transport-layer protocol that allows parachains to send messages between themselves, without
+//! going through the relay chain.
+//!
+//! ## HRMP (Horizontal Message Passing)
+//!
+//! Transport-layer protocol that allows a parachain to send messages to a sibling parachain going
+//! through the relay chain. It's a precursor to XCMP, also known as XCMP-lite.
+//! It uses a mixture of UMP and DMP.

Subject: [PATCH 019/106] Deprecate `dmp-queue` pallet (#4475)

`cumulus-pallet-dmp-queue` is not needed anymore since
https://github.com/paritytech/polkadot-sdk/pull/1246.

The only logic that remains in the pallet is a lazy migration in the
[`on_idle`](https://github.com/paritytech/polkadot-sdk/blob/8d62c13b2541920c37fb9d9ca733fcce91e96573/cumulus/pallets/dmp-queue/src/lib.rs#L158)
hook.

Subject: [PATCH 020/106] Remove pallet::getter usage from the bounties and
 child-bounties pallets (#4392)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

As per #3326, removes pallet::getter usage from the bounties and
child-bounties pallets. The syntax `StorageItem::<T, I>::get()` should
be used instead.

Changes to one pallet involved changes in the other, so I figured it'd
be best to combine these two.

Subject: [PATCH 021/106] [Runtime] Bound XCMP queue (#3952)

Re-applying #2302 after increasing the `MaxPageSize`.

Remove `without_storage_info` from the XCMP queue pallet. Part of
https://github.com/paritytech/polkadot-sdk/issues/323

Changes:
- Limit the number of messages and signals a HRMP channel can have at
most.
- Limit the number of HRML channels.

A No-OP migration is put in place to ensure that all `BoundedVec`s still
decode and not truncate after upgrade. The storage version is thereby
bumped to 5 to have our tooling remind us to deploy that migration.

## Integration

If you see this error in your try-runtime-cli:
```pre
Max message size for channel is too large. This means that the V5 migration can be front-run and an
attacker could place a large message just right before the migration to make other messages un-decodable.
Please either increase `MaxPageSize` or decrease the `max_message_size` for this channel. Channel max:
102400, MaxPageSize: 65535
```

Then increase the `MaxPageSize` of the `cumulus_pallet_xcmp_queue` to
something like this:
```rust
type MaxPageSize = ConstU32<{ 103 * 1024 }>;
```

There is currently no easy way for on-chain governance to adjust the
HRMP max message size of all channels, but it could be done:
https://github.com/paritytech/polkadot-sdk/issues/3145.

Subject: [PATCH 022/106] network/discovery: Add to DHT only peers that support
 genesis-based protocol (#3833)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This PR adds to the DHT only the peers that support the genesis/fork/kad
protocol.
Before this PR, any peer that supported the legacy `/kad/[id]` protocol
was added to the DHT.

This is the first step in removing the support for the legacy kad
protocols.

While I have adjusted unit tests to validate the appropriate behavior,
this still needs proper testing in our stack.

Subject: [PATCH 023/106] Bridge: drop subscriptions when they are no longer
 required (#4481)

The bridge relay is **not** using `tokio`, while `jsonrpsee` does. To
make it work together, we are spawning a separate tokio task for every
jsonrpsee subscription, which holds a subscription reference. It looks
like we are not stopping those tasks when we no longer need it and when
there are more than `1024` active subscriptions, `jsonrpsee` stops
opening new subscriptions. This PR adds an `cancel` signal that is sent
to the background task when we no longer need a subscription.

Subject: [PATCH 024/106] Demote per-peer validation slots warning to debug
 (#4480)

Demote `Ignored block announcement because all validation slots for this
peer are occupied.` message to debug level.

This is mostly an indicator of somebody spamming the node or (more
likely) some node actively keeping up with the network but not
recognizing it's in a major sync mode, so sending zillions of block
announcements (have seen this on Versi).

This warning shouldn't be considered an error by the end user, so let's
make it debug.

Ref. https://github.com/paritytech/polkadot-sdk/issues/1929.

Subject: [PATCH 025/106] Remove pallet::getter usage from the democracy pallet
 (#4472)

As per #3326, removes usage of the pallet::getter macro from the
democracy pallet. The syntax `StorageItem::<T, I>::get()` should be used
instead.

Subject: [PATCH 026/106] Snowbridge - Ethereum Client - Reject finalized
 updates without a sync committee in next store period (#4478)

While syncing Ethereum consensus updates to the Snowbridge Ethereum
light client, the syncing process stalled due to error
`InvalidSyncCommitteeUpdate` when importing the next sync committee for
period `1087`.

This bug manifested specifically because our light client checkpoint is
a few weeks old (submitted to governance weeks ago) and had to catchup
until a recent block. Since then, we have done thorough testing of the
catchup sync process.

### Symptoms
- Import next sync committee for period `1086` (essentially period
`1087`). Light client store period = `1086`.
- Import header in period `1087`. Light client store period = `1087`.
The current and next sync committee is not updated, and is now in an
outdated state. (current sync committee = `1086` and current sync
committee = `1087`, where it should be current sync committee = `1087`
and current sync committee = `None`)
- Import next sync committee for period `1087` (essentially period
`1088`) fails because the expected next sync committee's roots don't
match.

### Bug
The bug here is that the current and next sync committee's didn't
handover when an update in the next period was received.

### Fix
There are two possible fixes here:
1. Correctly handover sync committees when a header in the next period
is received.
2. Reject updates in the next period until the next sync committee
period is known.

We opted for solution 2, which is more conservative and requires less
changes.

### Polkadot-sdk versions
This fix should be backported in polkadot-sdk versions 1.7 and up.

+title: Add `MaxRank` Config to `pallet-core-fellowship` 
+
+doc:
+  - audience: Runtime User
+    description: |
+      This PR adds a new Config `MaxRank` to the core fellowship pallet. Initially, the maximum rank was set to IX (Grand Master) on the core-fellowship pallet, corresponding to the establishment of the Technical Fellowship and setting the default member count to nine. However, with the introduction of new collectives, this maximum rank is expected to evolve.

Subject: [PATCH 028/106] Contracts: remove kitchensink dynamic parameters
 (#4489)

Using Dynamic Parameters for contracts seems like a bad idea for now.

Given that we have benchmarks for each host function (in addition to our
extrinsics), parameter storage reads will be counted multiple times. We
will work on updates to the benchmarking framework to mitigate this
issue in future iterations.

Subject: [PATCH 029/106] Bridge: fixed relayer version metric value (#4492)

Before relayer crates have been moved + merged, the `MetricsParams` type
has been created from a `substrate-relay` crate (binary) and hence it
has been setting the `substrate_relay_build_info` metic value properly -
to the binary version. Now it is created from the
`substrate-relay-helper` crate, which has the fixed (it isn't published)
version `0.1.0`, so our relay provides incorrect metric value. This
'breaks' our monitoring tools - we see that all relayers have that
incorrect version, which is not cool.

The idea is to have a global static variable (shame on me) that is
initialized by the binary during initialization like we do with the
logger initialization already. Was considering some alternative options:
- adding a separate argument to every relayer subcommand and propagating
it to the `MetricsParams::new()` causes a lot of changes and introduces
even more noise to the binary code, which is supposed to be as small as
possible in the new design. But I could do that if team thinks it is
better;
- adding a `structopt(skip) pub relayer_version: RelayerVersion`
argument to all subcommand params won't work, because it will be
initialized by default and `RelayerVersion` needs to reside in some util
crate (not the binary), so it'll have the wrong value again.

Subject: [PATCH 032/106] Allow pool to be destroyed with an extra (erroneous)
 consumer reference on the pool account (#4503)

addresses https://github.com/paritytech/polkadot-sdk/issues/4440 (will
close once we have this in prod runtimes).
related: https://github.com/paritytech/polkadot-sdk/issues/2037.

An extra consumer reference is preventing pools to be destroyed. When a
pool is ready to be destroyed, we
can safely clear the consumer references if any. Notably, I only check
for one extra consumer reference since that is a known bug. Anything
more indicates possibly another issue and we probably don't want to
silently absorb those errors as well.

After this change, pools with extra consumer reference should be able to
destroy normally.

+title: "[Contracts] Remove internal topic index"
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      This PR removes topics from internal events emitted by pallet_contracts. It does not touch the `deposit_event` host function used by 
+      smart contracts that can still include topics.
+      Event topics incurs significant Storage costs, and are only used by light clients to index events and avoid downloading the entire block.
+      They are not used by Dapp or Indexers that download the whole block anyway.

Subject: [PATCH 037/106] Remove the prospective-parachains subsystem from
 collators (#4471)

Implements https://github.com/paritytech/polkadot-sdk/issues/4429

Collators only need to maintain the implicit view for the paraid they
are collating on.
In this case, bypass prospective-parachains entirely. It's still useful
to use the GetMinimumRelayParents message from prospective-parachains
for validators, because the data is already present there.

This enables us to entirely remove the subsystem from collators, which
consumed resources needlessly

Aims to resolve https://github.com/paritytech/polkadot-sdk/issues/4167

TODO:
- [x] fix unit tests

+      Removes the prospective-parachains subsystem from collators. The GetMinimumRelayParents of the implicit view
+      is replaced by direct ChainAPI and runtime calls. The subsystem was causing performance problems when collating
+      connected to an RPC node, due to the high number of runtime API calls, which were unneccessary for a collator.

Subject: [PATCH 039/106] Fixed RPC subscriptions leak when subscription stream
 is finished (#4533)

closes https://github.com/paritytech/parity-bridges-common/issues/3000

Recently we've changed our bridge configuration for Rococo <> Westend
and our new relayer has started to submit transactions every ~ `30`
seconds. Eventually, it switches itself into limbo state, where it can't
submit more transactions - all `author_submitAndWatchExtrinsic` calls
are failing with the following error: `ERROR bridge Failed to send
transaction to BridgeHubRococo node: Call(ErrorObject { code:
ServerError(-32006), message: "Too many subscriptions on the
connection", data: Some(RawValue("Exceeded max limit of 1024")) })`.

Some links for those who want to explore:
- server side (node) has a strict limit on a number of active
subscriptions. It fails to open a new subscription if this limit is hit:
https://github.com/paritytech/jsonrpsee/blob/a4533966b997e83632509ad97eea010fc7c3efc0/server/src/middleware/rpc/layer/rpc_service.rs#L122-L132.
The limit is set to `1024` by default;
- internally this limit is a semaphore with `limit` permits:
https://github.com/paritytech/jsonrpsee/blob/a4533966b997e83632509ad97eea010fc7c3efc0/core/src/server/subscription.rs#L461-L485;
- semaphore permit is acquired in the first link;
- the permit is "returned" when the `SubscriptionSink` is dropped:
https://github.com/paritytech/jsonrpsee/blob/a4533966b997e83632509ad97eea010fc7c3efc0/core/src/server/subscription.rs#L310-L325;
- the `SubscriptionSink` is dropped when [this `polkadot-sdk`
function](https://github.com/paritytech/polkadot-sdk/blob/278486f9bf7db06c174203f098eec2f91839757a/substrate/client/rpc/src/utils.rs#L58-L94)
returns. In other words - when the connection is closed, the stream is
finished or internal subscription buffer limit is hit;
- the subscription has the internal buffer, so sending an item contains
of two steps: [reading an item from the underlying
stream](https://github.com/paritytech/polkadot-sdk/blob/278486f9bf7db06c174203f098eec2f91839757a/substrate/client/rpc/src/utils.rs#L125-L141)
and [sending it over the
connection](https://github.com/paritytech/polkadot-sdk/blob/278486f9bf7db06c174203f098eec2f91839757a/substrate/client/rpc/src/utils.rs#L111-L116);
- when the underlying stream is finished, the `inner_pipe_from_stream`
wants to ensure that all items are sent to the subscriber. So it: [waits
until the current send operation
completes](https://github.com/paritytech/polkadot-sdk/blob/278486f9bf7db06c174203f098eec2f91839757a/substrate/client/rpc/src/utils.rs#L146-L148)
and then [send all remaining items from the internal
buffer](https://github.com/paritytech/polkadot-sdk/blob/278486f9bf7db06c174203f098eec2f91839757a/substrate/client/rpc/src/utils.rs#L150-L155).
Once it is done, the function returns, the `SubscriptionSink` is
dropped, semaphore permit is dropped and we are ready to accept new
subscriptions;
- unfortunately, the code just calls the `pending_fut.await.is_err()` to
ensure that [the current send operation
completes](https://github.com/paritytech/polkadot-sdk/blob/278486f9bf7db06c174203f098eec2f91839757a/substrate/client/rpc/src/utils.rs#L146-L148).
But if there are no current send operation (which is normal), then the
`pending_fut` is set to terminated future and the `await` never
completes. Hence, no return from the function, no drop of
`SubscriptionSink`, no drop of semaphore permit, no new subscriptions
allowed (once number of susbcriptions hits the limit.

I've illustrated the issue with small test - you may ensure that if e.g.
the stream is initially empty, the
`subscription_is_dropped_when_stream_is_empty` will hang because
`pipe_from_stream` never exits.

Subject: [PATCH 040/106] Bridge: added force_set_pallet_state call to
 pallet-bridge-grandpa (#4465)

closes https://github.com/paritytech/parity-bridges-common/issues/2963

See issue above for rationale
I've been thinking about adding similar calls to other pallets, but:
- for parachains pallet I haven't been able to think of a case when we
will need that given how long referendum takes. I.e. if storage proof
format changes and we want to unstuck the bridge, it'll take a large a
few weeks to sync a single parachain header, then another weeks for
another and etc.
- for messages pallet I've made the similar call initially, but it just
changes a storage key (`OutboundLanes` and/or `InboundLanes`), so
there's no any logic here and it may be simply done using
`system.set_storage`.

From d05786ffb5523c334f10d16870c2e73674661a52 Mon Sep 17 00:00:00 2001
From: Dmitry Markin <dmitry@markin.tech>

Subject: [PATCH 041/106] Replace `Multiaddr` & related types with
 substrate-specific types (#4198)

This PR introduces custom types / substrate wrappers for `Multiaddr`,
`multiaddr::Protocol`, `Multihash`, `ed25519::*` and supplementary types
like errors and iterators.

This is needed to unblock `libp2p` upgrade PR
https://github.com/paritytech/polkadot-sdk/pull/1631 after
https://github.com/paritytech/polkadot-sdk/pull/2944 was merged.
`libp2p` and `litep2p` currently depend on different versions of
`multiaddr` crate, and introduction of this "common ground" types is
needed to support independent version upgrades of `multiaddr` and
dependent crates in `libp2p` & `litep2p`.

While being just convenient to not tie versions of `libp2p` & `litep2p`
dependencies together, it's currently not even possible to keep `libp2p`
& `litep2p` dependencies updated to the same versions as `multiaddr` in
`libp2p` depends on `libp2p-identity` that we can't include as a
dependency of `litep2p`, which has it's own `PeerId` type. In the
future, to keep things updated on `litep2p` side, we will likely need to
fork `multiaddr` and make it use `litep2p` `PeerId` as a payload of
`/p2p/...` protocol.

With these changes, common code in substrate uses these custom types,
and `litep2p` & `libp2p` backends use corresponding libraries types.

Subject: [PATCH 049/106] Implement `CheckMetadataHash` extension (#4274)

This implements the `CheckMetadataHash` extension as described in
[RFC78](https://polkadot-fellows.github.io/RFCs/approved/0078-merkleized-metadata.html).

Besides the signed extension, the `substrate-wasm-builder` is extended
to support generating the metadata-hash.

Closes: https://github.com/paritytech/polkadot-sdk/issues/291

+//! # Enable metadata hash verification
+//!
+//! This guide will teach you how to enable the metadata hash verification in your runtime.
+//!
+//! ## What is metadata hash verification?
+//!
+//! Each FRAME based runtime exposes metadata about itself. This metadata is used by consumers of
+//! the runtime to interpret the state, to construct transactions etc. Part of this metadata are the
+//! type information. These type information can be used to e.g. decode storage entries or to decode
+//! a transaction. So, the metadata is quite useful for wallets to interact with a FRAME based
+//! chain. Online wallets can fetch the metadata directly from any node of the chain they are
+//! connected to, but offline wallets can not do this. So, for the offline wallet to have access to
+//! the metadata it needs to be transferred and stored on the device. The problem is that the
+//! metadata has a size of several hundreds of kilobytes, which takes quite a while to transfer to
+//! these offline wallets and the internal storage of these devices is also not big enough to store
+//! the metadata for one or more networks. The next problem is that the offline wallet/user can not
+//! trust the metadata to be correct. It is very important for the metadata to be correct or
+//! otherwise an attacker could change them in a way that the offline wallet decodes a transaction
+//! in a different way than what it will be decoded to on chain. So, the user may signs an incorrect
+//! transaction leading to unexpecting behavior.
+//!
+//! The metadata hash verification circumvents the issues of the huge metadata and the need to trust
+//! some metadata blob to be correct. To generate a hash for the metadata, the metadata is chunked,
+//! these chunks are put into a merkle tree and then the root of this merkle tree is the "metadata
+//! hash". For a more technical explanation on how it works, see
+//! [RFC78](https://polkadot-fellows.github.io/RFCs/approved/0078-merkleized-metadata.html). At compile
+//! time the metadata hash is generated and "backed" into the runtime. This makes it extremely cheap
+//! for the runtime to verify on chain that the metadata hash is correct. By having the runtime
+//! verify the hash on chain, the user also doesn't need to trust the offchain metadata. If the
+//! metadata hash doesn't match the on chain metadata hash the transaction will be rejected. The
+//! metadata hash itself is added to the data of the transaction that is signed, this means the
+//! actual hash does not appear in the transaction. On chain the same procedure is repeated with the
+//! metadata hash that is known by the runtime and if the metadata hash doesn't match the signature
+//! verification will fail. As the metadata hash is actually the root of a merkle tree, the offline
+//! wallet can get proofs of individual types to decode a transaction. This means that the offline
+//! wallet does not require the entire metadata to be present on the device.
+//!
+//! ## Integrating metadata hash verification into your runtime
+//!
+//! The integration of the metadata hash verification is split into two parts, first the actual
+//! integration into the runtime and secondly the enabling of the metadata hash generation at
+//! compile time.
+//!
+//! ### Runtime integration
+//!
+//! From the runtime side only the
+//! [`CheckMetadataHash`](frame_metadata_hash_extension::CheckMetadataHash) needs to be added to the
+//! list of signed extension:
+#![doc = docify::embed!("../../templates/parachain/runtime/src/lib.rs", template_signed_extra)]
+//!
+//! > **Note:**
+//! >
+//! > Adding the signed extension changes the encoding of the transaction and adds one extra byte
+//! > per transaction!
+//!
+//! This signed extension will make sure to decode the requested `mode` and will add the metadata
+//! hash to the signed data depending on the requested `mode`. The `mode` gives the user/wallet
+//! control over deciding if the metadata hash should be verified or not. The metadata hash itself
+//! is drawn from the `RUNTIME_METADATA_HASH` environment variable. If the environment variable is
+//! not set, any transaction that requires the metadata hash is rejected with the error
+//! `CannotLookup`. This is a security measurement to prevent including invalid transactions.
+//!
+//! <div class="warning">
+//!
+//! The extension does not work with the native runtime, because the
+//! `RUNTIME_METADATA_HASH` environment variable is not set when building the
+//! `frame-metadata-hash-extension` crate.
+//!
+//! </div>
+//!
+//! ### Enable metadata hash generation
+//!
+//! The metadata hash generation needs to be enabled when building the wasm binary. The
+//! `substrate-wasm-builder` supports this out of the box:
+#![doc = docify::embed!("../../templates/parachain/runtime/build.rs", template_enable_metadata_hash)]
+//!
+//! > **Note:**
+//! >
+//! > The `metadata-hash` feature needs to be enabled for the `substrate-wasm-builder` to enable the
+//! > code for being able to generate the metadata hash. It is also recommended to put the metadata
+//! > hash generation behind a feature in the runtime as shown above. The reason behind is that it
+//! > adds a lot of code which increases the compile time and the generation itself also increases
+//! > the compile time. Thus, it is recommended to enable the feature only when the metadata hash is
+//! > required (e.g. for an on-chain build).
+//!
+//! The two parameters to `enable_metadata_hash` are the token symbol and the number of decimals of
+//! the primary token of the chain. These information are included for the wallets to show token
+//! related operations in a more user friendly way.

+title: Introduce `CheckMetadataHash` signed extension
+
+doc:
+  - audience: Runtime Dev
+    description: |
+       Introduces the new `CheckMetadataHash` signed extension. This extension can be added to a
+       runtime to support verifying the metadata hash as described in
+       [RFC78](https://polkadot-fellows.github.io/RFCs/approved/0078-merkleized-metadata.html).
+       This removes the requirement for having a metadata portal and in general a centralized
+       authentication of the metadata. With this signed extension the runtime is able to verify
+       that the metadata used by the wallet was correct. This is mainly useful for offline wallets
+       which users need to trust any way, not that useful for online wallets.
+
+       There is a guide `generate_metadata_hash` for how to integrate this into a runtime that
+       should make it quite easy to integrate the signed extension.
+  - audience: Runtime User
+    description: |
+       This brings support for the new Ledger app and similar hardware wallets. These hardware
+       wallets will be able to decode the transaction using the metadata. The runtime will
+       ensure that the metadata used for this decoding process is correct and that the online
+       wallet did not tried to trick you.

+/// Extension for optionally verifying the metadata hash.
+///
+/// The metadata hash is cryptographical representation of the runtime metadata. This metadata hash
+/// is build as described in [RFC78](https://polkadot-fellows.github.io/RFCs/approved/0078-merkleized-metadata.html).
+/// This metadata hash should give users the confidence that what they build with an online wallet
+/// is the same they are signing with their offline wallet and then applying on chain. To ensure
+/// that the online wallet is not tricking the offline wallet into decoding and showing an incorrect
+/// extrinsic, the offline wallet will include the metadata hash into the additional signed data and
+/// the runtime will then do the same. If the metadata hash doesn't match, the signature
+/// verification will fail and thus, the transaction will be rejected. The RFC contains more details
+/// on how it works.
+///
+/// The extension adds one byte (the `mode`) to the size of the extrinsic. This one byte is
+/// controlling if the metadata hash should be added to the signed data or not. Mode `0` means that
+/// the metadata hash is not added and thus, `None` is added to the signed data. Mode `1` means that
+/// the metadata hash is added and thus, `Some(metadata_hash)` is added to the signed data. Further
+/// values of `mode` are reserved for future changes.
+///
+/// The metadata hash is read from the environment variable `RUNTIME_METADATA_HASH`. This
+/// environment variable is for example set by the `substrate-wasm-builder` when the feature for
+/// generating the metadata hash is enabled. If the environment variable is not set and `mode = 1`
+/// is passed, the transaction is rejected with [`UnknownTransaction::CannotLookup`].

## Summary of various roles 🤯
### Pallet Staking
**Nominator**: An account that directly stakes on `pallet-staking` and
nominates a set of validators.
**Stakers**: Common term for nominators and validators.
Virtual Stakers: Same as stakers, but they are keyless accounts and
their locks are managed by a pallet external to `pallet-staking`.

### Pallet Delegated Staking
**Agent**: An account that receives delegation from other accounts
(delegators) and stakes on their behalf. They are also Virtual Stakers
in `pallet-staking` where `pallet-delegated-staking` manages its locks.
**Delegator**: An account that delegates some funds to an agent.

### Pallet Nomination Pools
**Pool account**: Keyless account of a pool where funds are pooled.
Members pledge their funds towards the pools. These are going to become
`Agent` accounts in `pallet-delegated-staking`.
**Pool Members**: They are individual members of the pool who
contributed funds to it. They are also `Delegator` in
`pallet-delegated-staking`.

## Changes
### Multiple Stake strategies

**TransferStake**: The current nomination pool logic can be considered a
staking strategy where delegators transfer funds to pool and stake. In
this scenario, funds are locked in pool account, and users lose the
control of their funds.

**DelegateStake**: With this PR, we introduce a new staking strategy
where individual delegators delegate fund to pool. `Delegate` implies
funds are locked in delegator account itself. Important thing to note
is, pool does not have funds of its own, but it has authorization from
its members to use these funds for staking.

We extract out all the interaction of pool with staking interface into a
new trait `StakeStrategy`. This is the logic that varies between the
above two staking strategies. We use the trait `StakeStrategy` to
implement above two strategies: `TransferStake` and `DelegateStake`.

### NominationPool
Consumes an implementation of `StakeStrategy` instead of
`StakingInterface`. I have renamed it from `Staking` to `StakeAdapter`
to clarify the difference from the earlier used trait.

To enable delegation based staking in pool, Nomination pool can be
configured as:
```
type StakeAdapter = pallet_nomination_pools::adapter::DelegateStake<Self, DelegatedStaking>;
```

Note that with the following configuration, the changes in the PR are
no-op.
```
type StakeAdapter = pallet_nomination_pools::adapter::TransferStake<Self, Staking>;
```

## Deployment roadmap
Plan to enable this only in Westend. In production runtimes, we can keep
pool to use `TransferStake` which will be no functional change.

Once we have a full audit, we can enable this in Kusama followed by
Polkadot.

## TODO
- [x] Runtime level (Westend) migration for existing nomination pools.
- [x] Permissionless call/ pallet::tasks for claiming delegator funds.
- [x] Add/update benches.
- [x] Migration tests.
- [x] Storage flag to mark `DelegateStake` migration and integrity
checks to not allow `TransferStake` for migrated runtimes.

+title: Allows Nomination Pool to use different staking strategies including a new DelegateStake strategy.
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      This PR introduces a new staking strategy called `DelegateStake`. This strategy allows the nomination pool to
+      delegate its stake to a validator, that is, funds are locked in user account itself instead of being transferred
+      to the pool account. Includes migration of pools to this strategy for Westend.

Subject: [PATCH 054/106] Contracts: Rework host fn benchmarks (#4233)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

fix https://github.com/paritytech/polkadot-sdk/issues/4163

This PR does the following:
Update to pallet-contracts-proc-macro:
- Parse #[cfg] so we can add a dummy noop host function for benchmark.
- Generate BenchEnv::<host_fn> so we can call host functions directly in
the benchmark.
- Add the weight of the noop host function before calling the host
function itself

Update benchmarks:
- Update all host function benchmark, a host function benchmark now
simply call the host function, instead of invoking the function n times
from within a contract.
- Refactor RuntimeCosts & Schedule, for most host functions, we can now
use the generated weight function directly instead of computing the diff
with the cost! macro

```rust
// Before
#[benchmark(pov_mode = Measured)]
fn seal_input(r: Linear<0, API_BENCHMARK_RUNS>) {
    let code = WasmModule::<T>::from(ModuleDefinition {
        memory: Some(ImportedMemory::max::<T>()),
        imported_functions: vec![ImportedFunction {
            module: "seal0",
            name: "seal_input",
            params: vec![ValueType::I32, ValueType::I32],
            return_type: None,
        }],
        data_segments: vec![DataSegment { offset: 0, value: 0u32.to_le_bytes().to_vec() }],
        call_body: Some(body::repeated(
            r,
            &[
                Instruction::I32Const(4), // ptr where to store output
                Instruction::I32Const(0), // ptr to length
                Instruction::Call(0),
            ],
        )),
        ..Default::default()
    });

    call_builder!(func, code);

    let res;
    #[block]
    {
        res = func.call();
    }
    assert_eq!(res.did_revert(), false);
}
```

```rust
// After
fn seal_input(n: Linear<0, { code::max_pages::<T>() * 64 * 1024 - 4 }>) {
    let mut setup = CallSetup::<T>::default();
    let (mut ext, _) = setup.ext();
    let mut runtime = crate::wasm::Runtime::new(&mut ext, vec![42u8; n as usize]);
    let mut memory = memory!(n.to_le_bytes(), vec![0u8; n as usize],);
    let result;
    #[block]
    {
        result = BenchEnv::seal0_input(&mut runtime, &mut memory, 4, 0)
    }
    assert_ok!(result);
    assert_eq!(&memory[4..], &vec![42u8; n as usize]);
}
```

Subject: [PATCH 055/106] Define `OpaqueValue` (#4550)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Define `OpaqueValue` and use it instead of
`grandpa::OpaqueKeyOwnershipProof` and `beefy:OpaqueKeyOwnershipProof`

Related to
https://github.com/paritytech/polkadot-sdk/pull/4522#discussion_r1608278279

We'll need to introduce a runtime API method that calls the
`report_fork_voting_unsigned()` extrinsic. This method will need to
receive the ancestry proof as a paramater. I'm still not sure, but there
is a chance that we'll send the ancestry proof as an opaque type.

So let's introduce this `OpaqueValue`. We can already use it to replace
`grandpa::OpaqueKeyOwnershipProof` and `beefy:OpaqueKeyOwnershipProof`
and maybe we'll need it for the ancestry proof as well.

Subject: [PATCH 056/106] Mention new XCM docs in sdk docs (#4558)

The XCM docs were pretty much moved to the new rust docs format in
https://github.com/paritytech/polkadot-sdk/pull/2633, with the addition
of the XCM cookbook, which I plan to add more examples to shortly.

These docs were not mentioned in the polkadot-sdk rust docs, this PR
just mentions them there, so people can actually find them.

From: Branislav Kontur <bkontur@gmail.com>
Date: Fri, 24 May 2024 12:01:10 +0200
Subject: [PATCH 058/106] Attempt to avoid specifying `BlockHashCount` for
 different `mocking::{MockBlock, MockBlockU32, MockBlockU128}` (#4543)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

While doing some migration/rebase I came in to the situation, where I
needed to change `mocking::MockBlock` to `mocking::MockBlockU32`:
```
#[derive_impl(frame_system::config_preludes::TestDefaultConfig)]
impl frame_system::Config for TestRuntime {
	type Block = frame_system::mocking::MockBlockU32<TestRuntime>;
	type AccountData = pallet_balances::AccountData<ThisChainBalance>;
}
```
But actual `TestDefaultConfig` for `frame_system` is using `ConstU64`
for `type BlockHashCount = frame_support::traits::ConstU64<10>;`
[here](https://github.com/paritytech/polkadot-sdk/blob/master/substrate/frame/system/src/lib.rs#L303).
Because of this, it force me to specify and add override for `type
BlockHashCount = ConstU32<10>`.

This PR tries to fix this with `TestBlockHashCount` implementation for
`TestDefaultConfig` which supports `u32`, `u64` and `u128` as a
`BlockNumber`.

### How to simulate error
Just by removing `type BlockHashCount = ConstU32<250>;`
[here](https://github.com/paritytech/polkadot-sdk/blob/master/substrate/frame/multisig/src/tests.rs#L44)
```

    = note: this error originates in the attribute macro `derive_impl` which comes from the expansion of the macro `frame_support::macro_magic::forward_tokens_verbatim` (in Nightly builds, run with -Z macro-backtrace for more info)

For more information about this error, try `rustc --explain E0277`.
error: could not compile `pallet-multisig` (lib test) due to 1 previous error
```




## For reviewers:

(If there is a better solution, please let me know!)

The first commit contains actual attempt to fix the problem:
https://github.com/paritytech/polkadot-sdk/commit/3c5499e539f2218503fbd6ce9be085b03c31ee13.
The second commit is just removal of `BlockHashCount` from all other
places where not needed by default.

Closes: https://github.com/paritytech/polkadot-sdk/issues/1657

From: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io>
Date: Fri, 24 May 2024 13:55:58 +0200
Subject: [PATCH 059/106] Remove litep2p git dependency (#4560)

@serban300 could you please do the same for the MMR crate? Am not sure
what commit was released since there are no release tags in the repo.

Subject: [PATCH 060/106] Polkadot-SDK Umbrella Crate (#3935)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# Umbrella Crate

The Polkadot-SDK "umbrella" is a crate that re-exports all other
published crates. This makes it
possible to have a very small `Cargo.toml` file that only has one
dependency, the umbrella
crate. This helps with selecting the right combination of crate
versions, since otherwise 3rd
party tools are needed to select a compatible set of versions.

## Features

The umbrella crate supports no-std builds and can therefore be used in
the runtime and node.
There are two main features: `runtime` and `node`. The `runtime` feature
enables all `no-std`
crates, while the `node` feature enables all `std` crates. It should be
used like any other
crate in the repo, with `default-features = false`.

For more fine-grained control, additionally, each crate can be enabled
selectively. The umbrella
exposes one feature per dependency. For example, if you only want to use
the `frame-support`
crate, you can enable the `frame-support` feature.

The umbrella exposes a few more general features:
- `tuples-96`: Needs to be enabled for runtimes that have more than 64
pallets.
- `serde`: Specifically enable `serde` en/decoding support.
- `experimental`: Experimental enable experimental features - should not
yet used in production.
- `with-tracing`: Enable tracing support.
- `try-runtime`, `runtime-benchmarks` and `std`: These follow the
standard conventions.
- `runtime`: As described above, enable all `no-std` crates.
- `node`: As described above, enable all `std` crates.
- There does *not* exist a dedicated docs feature. To generate docs,
enable the `runtime` and
`node` feature. For docs.rs the manifest contains specific configuration
to make it show up
  all re-exports.

There is a specific `zepter` check in place to ensure that the features
of the umbrella are
correctly configured. This check is run in CI and locally when running
`zepter`.

## Generation

The umbrella crate needs to be updated every time when a new crate is
added or removed from the
workspace. It is checked in CI by calling its generation script. The
generation script is
located in `./scripts/generate-umbrella.py` and needs dependency
`cargo_workspace`.

Example: `python3 scripts/generate-umbrella.py --sdk . --version 1.9.0`

## Usage

> Note: You can see a live example in the `staging-node-cli` and
`kitchensink-runtime` crates.

The umbrella crate can be added to your runtime crate like this:

`polkadot-sdk = { path = "../../../../umbrella", features = ["runtime"],
default-features =
false}`

or for a node:

`polkadot-sdk = { path = "../../../../umbrella", features = ["node"],
default-features = false
}`

In the code, it is then possible to bring all dependencies into scope
via:

`use polkadot_sdk::*;`

### Known Issues

The only known issue so far is the fact that the `use` statement brings
the dependencies only
into the outer module scope - not the global crate scope. For example,
the following code would
need to be adjusted:

```rust
use polkadot_sdk::*;

mod foo {
   // This does sadly not compile:
   frame_support::parameter_types! { }

   // Instead, we need to do this (or add an equivalent `use` statement):
   polkadot_sdk::frame_support::parameter_types! { }
}
```

Apart from this, no issues are known. There could be some bugs with how
macros locate their own
re-exports. Please compile issues that arise from using this crate.

## Dependencies

The umbrella crate re-exports all published crates, with a few
exceptions:
- Runtime crates like `rococo-runtime` etc are not exported. This
otherwise leads to very weird
  compile errors and should not be needed anyway.
- Example and fuzzing crates are not exported. This is currently
detected by checking the name
of the crate for these magic words. In the future, it will utilize
custom metadata, as it is
  done in the `rococo-runtime` crate.
- The umbrella crate itself. Should be obvious :)

## Follow Ups
- [ ] Re-writing the generator in Rust - the python script is at its
limit.
- [ ] Using custom metadata to exclude some crates instead of filtering
by names.
- [ ] Finding a way to setting the version properly. Currently its
locked in the CI script.

+//! # Umbrella Crate
+//!
+//! The Polkadot-SDK "umbrella" is a crate that re-exports all other published crates. This makes it
+//! possible to have a very small `Cargo.toml` file that only has one dependency, the umbrella
+//! crate. This helps with selecting the right combination of crate versions, since otherwise 3rd
+//! party tools are needed to select a compatible set of versions.
+//!
+//! ## Features
+//!
+//! The umbrella crate supports no-std builds and can therefore be used in the runtime and node.
+//! There are two main features: `runtime` and `node`. The `runtime` feature enables all `no-std`
+//! crates, while the `node` feature enables all `std` crates. It should be used like any other
+//! crate in the repo, with `default-features = false`.
+//!
+//! For more fine-grained control, additionally, each crate can be enabled selectively. The umbrella
+//! exposes one feature per dependency. For example, if you only want to use the `frame-support`
+//! crate, you can enable the `frame-support` feature.
+//!
+//! The umbrella exposes a few more general features:
+//! - `tuples-96`: Needs to be enabled for runtimes that have more than 64 pallets.
+//! - `serde`: Specifically enable `serde` en/decoding support.
+//! - `experimental`: Experimental enable experimental features - should not yet used in production.
+//! - `with-tracing`: Enable tracing support.
+//! - `try-runtime`, `runtime-benchmarks` and `std`: These follow the standard conventions.
+//! - `runtime`: As described above, enable all `no-std` crates.
+//! - `node`: As described above, enable all `std` crates.
+//! - There does *not* exist a dedicated docs feature. To generate docs, enable the `runtime` and
+//!   `node` feature. For docs.rs the manifest contains specific configuration to make it show up
+//!   all re-exports.
+//!
+//! There is a specific `zepter` check in place to ensure that the features of the umbrella are
+//! correctly configured. This check is run in CI and locally when running `zepter`.
+//!
+//! ## Generation
+//!
+//! The umbrella crate needs to be updated every time when a new crate is added or removed from the
+//! workspace. It is checked in CI by calling its generation script. The generation script is
+//! located in `./scripts/generate-umbrella.py` and needs dependency `cargo_workspace`.
+//!
+//! Example: `python3 scripts/generate-umbrella.py --sdk . --version 1.9.0`
+//!
+//! ## Usage
+//!
+//! > Note: You can see a live example in the `staging-node-cli` and `kitchensink-runtime` crates.
+//!
+//! The umbrella crate can be added to your runtime crate like this:
+//!
+//! `polkadot-sdk = { path = "../../../../umbrella", features = ["runtime"], default-features =
+//! false }`
+//!
+//! or for a node:
+//!
+//! `polkadot-sdk = { path = "../../../../umbrella", features = ["node"], default-features = false
+//! }`
+//!
+//! In the code, it is then possible to bring all dependencies into scope via:
+//!
+//! `use polkadot_sdk::*;`
+//!
+//! ### Known Issues
+//!
+//! The only known issue so far is the fact that the `use` statement brings the dependencies only
+//! into the outer module scope - not the global crate scope. For example, the following code would
+//! need to be adjusted:
+//!
+//! ```rust
+//! use polkadot_sdk::*;
+//!
+//! mod foo {
+//!    // This does sadly not compile:
+//!    frame_support::parameter_types! { }
+//!
+//!    // Instead, we need to do this (or add an equivalent `use` statement):
+//!    polkadot_sdk::frame_support::parameter_types! { }
+//! }
+//! ```
+//!
+//! Apart from this, no issues are known. There could be some bugs with how macros locate their own
+//! re-exports. Please compile issues that arise from using this crate.
+//!
+//! ## Dependencies
+//!
+//! The umbrella crate re-exports all published crates, with a few exceptions:
+//! - Runtime crates like `rococo-runtime` etc are not exported. This otherwise leads to very weird
+//!   compile errors and should not be needed anyway.
+//! - Example and fuzzing crates are not exported. This is currently detected by checking the name
+//!   of the crate for these magic words. In the future, it will utilize custom metadata, as it is
+//!   done in the `rococo-runtime` crate.
+//! - The umbrella crate itself. Should be obvious :)

Subject: [PATCH 061/106] availability-recovery: bump chunk fetch threshold to
 1MB for Polkadot and 4MB for Kusama + testnets (#4399)

Doing this change ensures that we minimize the CPU usage we spend in
reed-solomon by only doing the re-encoding into chunks if PoV size is
less than 4MB (which means all PoVs right now)

Based on susbystem benchmark results we concluded that it is safe to
bump this number higher. At worst case scenario the network pressure for
a backing group of 5 is around 25% of the network bandwidth in hw specs.

Assuming 6s block times (max_candidate_depth 3) and needed_approvals 30
the amount of bandwidth usage of a backing group used would hover above
`30 * 4 * 3 = 360MB` per relay chain block. Given a backing group of 5
that gives 72MB per block per validator -> 12 MB/s.

Subject: [PATCH 064/106] Bridge: check submit_finality_proof limits before
 submission (#4549)

closes https://github.com/paritytech/parity-bridges-common/issues/2982
closes https://github.com/paritytech/parity-bridges-common/issues/2730

The main change is in the
bridges/relays/lib-substrate-relay/src/finality/target.rs, changes in
other files are just moving the code

~I haven't been able to run zn tests locally - don't know why, but it
keeps failing for me locally with: `
Error running script:
/home/svyatonik/dev/polkadot-sdk/bridges/testing/framework/js-helpers/wait-hrmp-channel-opened.js
Error: Timeout(300), "custom-js
/home/svyatonik/dev/polkadot-sdk/bridges/testing/framework/js-helpers/wait-hrmp-channel-opened.js
within 300 secs" didn't complete on time.`~ The issue was an obsolete
`polkadot-js-api` binary - did `yarn global upgrade` and it is ok now

Subject: [PATCH 069/106] network: Update litep2p to v0.5.0 (#4570)

## [0.5.0] - 2023-05-24

This is a small patch release that makes the `FindNode` command a bit
more robst:

- The `FindNode` command now retains the K (replication factor) best
results.
- The `FindNode` command has been updated to handle errors and
unexpected states without panicking.

### Changed

- kad: Refactor FindNode query, keep K best results and add tests
([#114](https://github.com/paritytech/litep2p/pull/114))

Subject: [PATCH 071/106] check-weight: Disable total pov size check for
 mandatory extrinsics (#4571)

So in some pallets we like
[here](https://github.com/paritytech/polkadot-sdk/blob/5dc522d02fe0b53be1517f8b8979176e489a388b/substrate/frame/session/src/lib.rs#L556)
we use `max_block` as return value for `on_initialize` (ideally we would
not).

This means the block is already full when we try to apply the inherents,
which lead to the error seen in #4559 because we are unable to include
the required inherents. This was not erroring before #4326 because we
were running into this branch:

https://github.com/paritytech/polkadot-sdk/blob/e4b89cc50c8d17868d6c8b122f2e156d678c7525/substrate/frame/system/src/extensions/check_weight.rs#L222-L224

The inherents are of `DispatchClass::Mandatory` and therefore have a
`reserved` value of `None` in all runtimes I have inspected. So they
will always pass the normal check.

So in this PR I adjust the `check_combined_proof_size` to return an
early `Ok(())` for mandatory extrinsics.

If we agree on this PR I will backport it to the 1.12.0 branch.

closes #4559

+title: Ignore mandatory extrinsics in total PoV size check
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      The `CheckWeight` extension is checking that extrinsic length and used storage proof
+      weight together do not exceed the PoV size limit. This lead to problems when
+      the PoV size was already reached before mandatory extrinsics were applied.The `CheckWeight`
+      extension will now allow extrinsics of `DispatchClass::Mandatory` to be applied even if
+      the limit is reached.

Subject: [PATCH 072/106] [subsystem-benchmarks] Add statement-distribution
 benchmarks (#3863)

Fixes https://github.com/paritytech/polkadot-sdk/issues/3748

Adds a subsystem benchmark for statements-distribution subsystem.

Results in CI (reference hw):
```

Subject: [PATCH 073/106] `sc-chain-spec`: deprecated code removed (#4410)

This PR removes deprecated code:
- The `RuntimeGenesisConfig` generic type parameter in
`GenericChainSpec` struct.
- `ChainSpec::from_genesis` method allowing to create chain-spec using
closure providing runtime genesis struct
- `GenesisSource::Factory` variant together with no longer needed
`GenesisSource`'s generic parameter `G` (which was intended to be a
runtime genesis struct).

From 09f07d548bf73633cd691e8346c630026444e073 Mon Sep 17 00:00:00 2001
From: Przemek Rzad <przemek@parity.io>
Date: Tue, 28 May 2024 09:37:26 +0200
Subject: [PATCH 074/106] Remove workspace lints from templates (#4598)

This detaches the templates from monorepo's workspace lints, so the
lints for the templates can evolve separately as needed.

Currently the templates [re-use the monorepo's
lints](https://github.com/paritytech/polkadot-sdk-minimal-template/blob/bd8afe66ec566d61f36b0e3d731145741a9e9e19/Cargo.toml#L16-L43)
which looks weird.

From 523e62560eb5d9a36ea75851f2fb15b9d7993f01 Mon Sep 17 00:00:00 2001

Subject: [PATCH 075/106] Add availability-recovery from systematic chunks
 (#1644)

**Don't look at the commit history, it's confusing, as this branch is
based on another branch that was merged**

Fixes #598
Also implements [RFC
#47](https://github.com/polkadot-fellows/RFCs/pull/47)

## Description

- Availability-recovery now first attempts to request the systematic
chunks for large POVs (which are the first ~n/3 chunks, which can
recover the full data without doing the costly reed-solomon decoding
process). This has a fallback of recovering from all chunks, if for some
reason the process fails. Additionally, backers are also used as a
backup for requesting the systematic chunks if the assigned validator is
not offering the chunk (each backer is only used for one systematic
chunk, to not overload them).
- Quite obviously, recovering from systematic chunks is much faster than
recovering from regular chunks (4000% faster as measured on my apple M2
Pro).
- Introduces a `ValidatorIndex` -> `ChunkIndex` mapping which is
different for every core, in order to avoid only querying the first n/3
validators over and over again in the same session. The mapping is the
one described in RFC 47.
- The mapping is feature-gated by the [NodeFeatures runtime
API](https://github.com/paritytech/polkadot-sdk/pull/2177) so that it
can only be enabled via a governance call once a sufficient majority of
validators have upgraded their client. If the feature is not enabled,
the mapping will be the identity mapping and backwards-compatibility
will be preserved.
- Adds a new chunk request protocol version (v2), which adds the
ChunkIndex to the response. This may or may not be checked against the
expected chunk index. For av-distribution and systematic recovery, this
will be checked, but for regular recovery, no. This is backwards
compatible. First, a v2 request is attempted. If that fails during
protocol negotiation, v1 is used.
- Systematic recovery is only attempted during approval-voting, where we
have easy access to the core_index. For disputes and collator
pov_recovery, regular chunk requests are used, just as before.

## Performance results

Some results from subsystem-bench:

with regular chunk recovery: CPU usage per block 39.82s
with recovery from backers: CPU usage per block 16.03s
with systematic recovery: CPU usage per block 19.07s

End-to-end results here:

+reconstructing the PoV from chunks (either from systematic chunks or regular chunks).
+You can see the results of running this bench on 5950x below (only including recovery from regular chunks).
 Interestingly, with `10_000` chunks (validators) its slower than with `50_000` for both construction
 and reconstruction.

 # Availability Recovery
 
-This subsystem is the inverse of the [Availability Distribution](availability-distribution.md) subsystem: validators
-will serve the availability chunks kept in the availability store to nodes who connect to them. And the subsystem will
-also implement the other side: the logic for nodes to connect to validators, request availability pieces, and
-reconstruct the `AvailableData`.
+This subsystem is responsible for recovering the data made available via the
+[Availability Distribution](availability-distribution.md) subsystem, neccessary for candidate validation during the
+approval/disputes processes. Additionally, it is also being used by collators to recover PoVs in adversarial scenarios
+where the other collators of the para are censoring blocks.
 
-This version of the availability recovery subsystem is based off of direct connections to validators. In order to
-recover any given `AvailableData`, we must recover at least `f + 1` pieces from validators of the session. Thus, we will
-connect to and query randomly chosen validators until we have received `f + 1` pieces.
+According to the Polkadot protocol, in order to recover any given `AvailableData`, we generally must recover at least
+`f + 1` pieces from validators of the session. Thus, we should connect to and query randomly chosen validators until we
+have received `f + 1` pieces.
+
+In practice, there are various optimisations implemented in this subsystem which avoid querying all chunks from
+different validators and/or avoid doing the chunk reconstruction altogether.
 
 ## Protocol
 
-`PeerSet`: `Validation`
+This version of the availability recovery subsystem is based only on request-response network protocols.
 
 Input:
 
-* `NetworkBridgeUpdate(update)`
-* `AvailabilityRecoveryMessage::RecoverAvailableData(candidate, session, backing_group, response)`
+* `AvailabilityRecoveryMessage::RecoverAvailableData(candidate, session, backing_group, core_index, response)`
 
 Output:
 
-* `NetworkBridge::SendValidationMessage`
-* `NetworkBridge::ReportPeer`
-* `AvailabilityStore::QueryChunk`
+* `NetworkBridgeMessage::SendRequests`
+* `AvailabilityStoreMessage::QueryAllChunks`
+* `AvailabilityStoreMessage::QueryAvailableData`
+* `AvailabilityStoreMessage::QueryChunkSize`
+
 
 ## Functionality
 
-We hold a state which tracks the currently ongoing recovery tasks, as well as which request IDs correspond to which
-task. A recovery task is a structure encapsulating all recovery tasks with the network necessary to recover the
-available data in respect to one candidate.

+
+### Recovery strategies
+
+#### `FetchFull`
+
+This strategy tries requesting the full available data from the validators in the backing group to
+which the node is already connected. They are tried one by one in a random order.
+It is very performant if there's enough network bandwidth and the backing group is not overloaded.
+The costly reed-solomon reconstruction is not needed.
+
+#### `FetchSystematicChunks`
+
+Very similar to `FetchChunks` below but requests from the validators that hold the systematic chunks, so that we avoid
+reed-solomon reconstruction. Only possible if `node_features::FeatureIndex::AvailabilityChunkMapping` is enabled and
+the `core_index` is supplied (currently only for recoveries triggered by approval voting).
+
+More info in
+[RFC-47](https://github.com/polkadot-fellows/RFCs/blob/main/text/0047-assignment-of-availability-chunks.md).
+
+#### `FetchChunks`
+
+The least performant strategy but also the most comprehensive one. It's the only one that cannot fail under the
+byzantine threshold assumption, so it's always added as the last one in the `recovery_strategies` queue.
+
+Performs parallel chunk requests to validators. When enough chunks were received, do the reconstruction.
+In the worst case, all validators will be tried.
+
+### Default recovery strategy configuration
+
+#### For validators
+
+If the estimated available data size is smaller than a configured constant (currently 1Mib for Polkadot or 4Mib for
+other networks), try doing `FetchFull` first.
+Next, if the preconditions described in `FetchSystematicChunks` above are met, try systematic recovery.
+As a last resort, do `FetchChunks`.
+
+#### For collators
+
+Collators currently only use `FetchChunks`, as they only attempt recoveries in rare scenarios.
 
-* Request `AvailabilityStoreMessage::QueryAvailableData`. If it exists, return that.
-* If the task contains `RequestFromBackers`
-  * Loop:
-    * If the `requesting_pov` is `Some`, poll for updates on it. If it concludes, set `requesting_pov` to `None`.
-    * If the `requesting_pov` is `None`, take the next backer off the `shuffled_backers`.
-        * If the backer is `Some`, issue a `NetworkBridgeMessage::Requests` with a network request for the
-          `AvailableData` and wait for the response.
-        * If it concludes with a `None` result, return to beginning.
-        * If it concludes with available data, attempt a re-encoding.
-            * If it has the correct erasure-root, break and issue a `Ok(available_data)`.
-            * If it has an incorrect erasure-root, return to beginning.
-        * Send the result to each member of `awaiting`.
-        * If the backer is `None`, set the source to `RequestChunksFromValidators` with a random shuffling of validators
-          and empty `received_chunks`, and `requesting_chunks` and break the loop.
-
-* If the task contains `RequestChunksFromValidators`:
-  * Request `AvailabilityStoreMessage::QueryAllChunks`. For each chunk that exists, add it to `received_chunks` and
-    remote the validator from `shuffling`.
-  * Loop:
-    * If `received_chunks + requesting_chunks + shuffling` lengths are less than the threshold, break and return
-      `Err(Unavailable)`.
-    * Poll for new updates from `requesting_chunks`. Check merkle proofs of any received chunks. If the request simply
-      fails due to network issues, insert into the front of `shuffling` to be retried.
-    * If `received_chunks` has more than `threshold` entries, attempt to recover the data.
-      * If that fails, return `Err(RecoveryError::Invalid)`
-      * If correct:
-        * If re-encoding produces an incorrect erasure-root, break and issue a `Err(RecoveryError::Invalid)`.
-        * break and issue `Ok(available_data)`
-    * Send the result to each member of `awaiting`.
-    * While there are fewer than `N_PARALLEL` entries in `requesting_chunks`,
-      * Pop the next item from `shuffling`. If it's empty and `requesting_chunks` is empty, return
-        `Err(RecoveryError::Unavailable)`.
-      * Issue a `NetworkBridgeMessage::Requests` and wait for the response in `requesting_chunks`.
+Moreover, the recovery task is specially configured to not attempt requesting data from the local availability-store
+(because it doesn't exist) and to not reencode the data after a succcessful recovery (because it's an expensive check
+that is not needed; checking the pov_hash is enough for collators).

+title: Add availability-recovery from systematic chunks
+
+doc:
+  - audience: Node Operator
+    description: |
+      Implements https://github.com/polkadot-fellows/RFCs/pull/47. This optimisation is guarded by a configuration bit in
+      the runtime and will only be enabled once a supermajority of the validators have upgraded to this version.
+      It's strongly advised to upgrade to this version.
+  - audience: Node Dev
+    description: |
+      Implements https://github.com/polkadot-fellows/RFCs/pull/47 and adds the logic for availability recovery from systematic chunks.
+      The /req_chunk/1 req-response protocol is now considered deprecated in favour of /req_chunk/2. Systematic recovery is guarded
+      by a configuration bit in the runtime (bit with index 2 of the node_features field from the HostConfiguration)
+      and must not be enabled until all (or almost all) validators have upgraded to the node version that includes
+      this PR.

Subject: [PATCH 076/106] [subsytem-bench] Remove redundant banchmark_name
 param (#4540)

Fixes https://github.com/paritytech/polkadot-sdk/issues/3601

Since we print benchmark results manually, we don't need to save
benchmark_name anywhere, better just put the name inside `println!`.

Date: Tue, 28 May 2024 18:27:01 +0400
Subject: [PATCH 078/106] Conditional `required` checks (#4544)

Workaround for skipped but `required` github checks. The idea is to
trigger the workflow but filter out unaffected jobs or steps. See [ci_cd
998](https://github.com/paritytech/ci_cd/issues/988) for details

In `.github/workflows/check-changed-files.yml` there is a reusable
workflow thad does all the checks and publishes results as outputs.
Example usage:
```
jobs:
  changes:
    permissions:
      pull-requests: read
    uses: ./.github/workflows/check-changed-files.yml
  some-job:
    needs: changes
    if: ${{ needs.changes.outputs.rust }}
 .......
 ```

Subject: [PATCH 080/106] Add metric to measure the time it takes to gather
 enough assignments (#4587)

To understand with high granularity how many assignment tranches are
triggered before we concur that we have enough assignments.

This metric is important because the triggering of an assignment creates
a lot of work in the system for approving the candidate and gossiping
the necessary messages.

Subject: [PATCH 082/106] Filter workspace dependencies in the templates
 (#4599)

This detaches the templates from monorepo's workspace dependencies.

Currently the templates [re-use the monorepo's
dependencies](https://github.com/paritytech/polkadot-sdk-minimal-template/blob/bd8afe66ec566d61f36b0e3d731145741a9e9e19/Cargo.toml#L45-L58),
most of which are not needed.

The simplest approach is to specify versions directly and not use
workspace dependencies in the templates.

Another approach would be to programmatically filter dependencies that
are actually needed - but not sure if it's worth it, given that it would
complicate the synchronization job.

Subject: [PATCH 083/106] Moves runtime macro out of experimental flag (#4249)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Step in https://github.com/paritytech/polkadot-sdk/issues/3688

Now that the `runtime` macro (Construct Runtime V2) has been
successfully deployed on Westend, this PR moves it out of the
experimental feature flag and makes it generally available for runtime
devs.

Subject: [PATCH 084/106] Add omni bencher & chain-spec-builder bins to release
 (#4557)

Closes: https://github.com/paritytech/polkadot-sdk/issues/4354

This PR adds the steps to build and attach `frame-omni-bencher` and
`chain-spec-builder` binaries to the release draft

## TODO
- [x] add also chain-spec-builder binary
- [ ] ~~check/investigate Kian's comment: `chain spec builder. Ideally I
want it to match the version of the sp-genesis-builder crate`~~ see
[comment](https://github.com/paritytech/polkadot-sdk/pull/4518#issuecomment-2134731355)
- [ ] Backport to `polkadot-sdk@1.11` release, so we can use it for next
fellows release: https://github.com/polkadot-fellows/runtimes/pull/324
- [ ] Backport to `polkadot-sdk@1.12` release

Subject: [PATCH 085/106] Publish `chain-spec-builder` (#4518)

marking it as release-able, attaching the same version number that is
attached to other binaries such as `polkadot` and `polkadot-parachain`.

I have more thoughts about the version number, though. The chain-spec
builder is mainly a user of the `sp-genesis-builder` api. So the
versioning should be such that it helps users know give a version of
`sp-genesis-builder` in their runtime, which version of
`chain-spec-builder` should they use?

With this, we can possibly alter the version number to always match
`sp-genesis-builder`.

Fixes https://github.com/paritytech/polkadot-sdk/issues/4352

- [x] Add to release artifacts ~~similar to
https://github.com/paritytech/polkadot-sdk/pull/4405~~ done here:
https://github.com/paritytech/polkadot-sdk/pull/4557

Subject: [PATCH 087/106] Change `XcmDryRunApi::dry_run_extrinsic` to take a
 call instead (#4621)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Follow-up to the new `XcmDryRunApi` runtime API introduced in
https://github.com/paritytech/polkadot-sdk/pull/3872.

Taking an extrinsic means the frontend has to sign first to dry-run and
once again to submit.
This is bad UX which is solved by taking an `origin` and a `call`.
This also has the benefit of being able to dry-run as any account, since
it needs no signature.

This is a breaking change since I changed `dry_run_extrinsic` to
`dry_run_call`, however, this API is still only on testnets.
The crates are bumped accordingly.

As a part of this PR, I changed the name of the API from `XcmDryRunApi`
to just `DryRunApi`, since it can be used for general dry-running :)

Step towards https://github.com/paritytech/polkadot-sdk/issues/690.

Example of calling the API with PAPI, not the best code, just testing :)

```ts
// We just build a call, the arguments make it look very big though.
const call = localApi.tx.XcmPallet.transfer_assets({
  dest: XcmVersionedLocation.V4({ parents: 0, interior: XcmV4Junctions.X1(XcmV4Junction.Parachain(1000)) }),
  beneficiary: XcmVersionedLocation.V4({ parents: 0, interior: XcmV4Junctions.X1(XcmV4Junction.AccountId32({ network: undefined, id: Binary.fromBytes(encodeAccount(account.address)) })) }),
  weight_limit: XcmV3WeightLimit.Unlimited(),
  assets: XcmVersionedAssets.V4([{
    id: { parents: 0, interior: XcmV4Junctions.Here() },
    fun: XcmV3MultiassetFungibility.Fungible(1_000_000_000_000n) }
  ]),
  fee_asset_item: 0,
});
// We call the API passing in a signed origin
const result = await localApi.apis.XcmDryRunApi.dry_run_call(
  WestendRuntimeOriginCaller.system(DispatchRawOrigin.Signed(account.address)),
  call.decodedCall
);
if (result.success && result.value.execution_result.success) {
  // We find the forwarded XCM we want. The first one going to AssetHub in this case.
  const xcmsToAssetHub = result.value.forwarded_xcms.find(([location, _]) => (
    location.type === "V4" &&
      location.value.parents === 0 &&
      location.value.interior.type === "X1"
      && location.value.interior.value.type === "Parachain"
      && location.value.interior.value.value === 1000
  ))!;

  // We can even find the delivery fees for that forwarded XCM.
  const deliveryFeesQuery = await localApi.apis.XcmPaymentApi.query_delivery_fees(xcmsToAssetHub[0], xcmsToAssetHub[1][0]);

  if (deliveryFeesQuery.success) {
    const amount = deliveryFeesQuery.value.type === "V4" && deliveryFeesQuery.value.value[0].fun.type === "Fungible" && deliveryFeesQuery.value.value[0].fun.value.valueOf() || 0n;
    // We store them in state somewhere.
    setDeliveryFees(formatAmount(BigInt(amount)));
  }
}
```

+title: Change XcmDryRunApi::dry_run_extrinsic to take a call instead
+
+doc:
+  - audience: Runtime User
+    description: |
+      The XcmDryRunApi now dry-run calls instead of extrinsics.
+      This means it's possible to dry-run an extrinsic before signing it,
+      allowing for seamless dry-running in dapps.
+      Additionally, calls can now be dry-run for different accounts.
+  - audience: Runtime Dev
+    description: |
+      The XcmDryRunApi::dry_run_extrinsic function was replaced by
+      XcmDryRunApi::dry_run_call.
+      This new function takes an origin (OriginCaller, the encodable inner variant)
+      and a call instead of an extrinsic.
+      This was needed to not require the user signing twice, once for the dry-run and
+      a second time to actually submit the extrinsic.
+      Additionally, calls can now be dry-run for different accounts.
+      The implementation for this runtime API is now simpler, being `call.dispatch(origin.into())`
+      instead of using the `Executive`.

Subject: [PATCH 088/106] Broker new price adapter (#4521)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes #4360

Also rename: AllowedRenewals -> PotentialRenewals to avoid confusion of
future readers. (An entry in `AllowedRenewals` is not enough to allow a
renewal, the assignment also has to be complete, which is only checked
afterwards.)

- [x] Does not work with renewals as is - fix.
- [x] More tests
- [x] PR docs

Edit 1:
(Relevant blog post:
https://grillapp.net/12935/agile-coretime-pricing-explained-166522?ref=29715)

+title: AdaptPrice trait is now price controlled
+
+doc:
+  - audience: Runtime Dev
+    description: |
+      The broker pallet price adaptation interface is changed to be less opinionated and more
+      information is made available to the `AdaptPrice` trait. A new example impl is included which
+      adapts the price based not on the number of cores sold, but rather on the price that was
+      achieved during the sale to mitigate a potential price manipulation vector. More information
+      here:
+
+        https://github.com/paritytech/polkadot-sdk/issues/4360
+
+  - audience: Runtime User
+    description: |
+      The price controller of the Rococo and Westend Coretime chain will be
+      adjusted with this release. This will very likely be used in the
+      fellowship production runtime to have a much larger leadin. This fixes a
+      price manipulation issue we discovered with the Kusama launch.

Subject: [PATCH 091/106] Fix broken windows build (#4636)

Fixes #4625.

Specifically, the `cfg` attribute `windows` refers to the compile target
and not the build environment, and in the case of cross-compilation, the
build environment and target can differ. However, the line modified is
related to documentation generation, so there should be no critical
issue with this change.

Subject: [PATCH 092/106] Adds ability to specify chain type in
 chain-spec-builder (#4542)

Currently, `chain-spec-builder` only creates a spec with `Live` chain
type. This PR adds the ability to specify it while keeping the same
default.

Validators already have been upgraded so they could already receive the
new `CollationWithParentHeadData` response when fetching collation.
However this is only sent by collators when the parachain has more than
1 core is assigned.

From fc6c31829fc2e24e11a02b6a2adec27bc5d8918f Mon Sep 17 00:00:00 2001
From: Francisco Aguirre <franciscoaguirreperez@gmail.com>

Subject: [PATCH 096/106] Implement `XcmPaymentApi` and `DryRunApi` on all
 system parachains (#4634)

Depends on https://github.com/paritytech/polkadot-sdk/pull/4621.

Implemented the
[`XcmPaymentApi`](https://github.com/paritytech/polkadot-sdk/pull/3607)
and [`DryRunApi`](https://github.com/paritytech/polkadot-sdk/pull/3872)
on all system parachains.

More scenarios can be tested on both rococo and westend if all system
parachains implement this APIs.
The objective is for all XCM-enabled runtimes to implement them.
After demonstrating fee estimation in a UI on the testnets, come the
fellowship runtimes.

Step towards https://github.com/paritytech/polkadot-sdk/issues/690.

Subject: [PATCH 099/106] [Pools] Refactors and runtime apis for DelegateStake
 (#4537)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

## Runtime Apis
Introduces the following runtime apis to facilitate dapps and wallets in
integrating with the `DelegateStake` functionalities of the pools
(related: https://github.com/paritytech/polkadot-sdk/pull/3905). These
apis are meant to support pool and member migration, as well as lazy
application of pending slashes of pool members.

```rust
fn pool_pending_slash(pool_id: PoolId) -> Balance;
fn member_pending_slash(member: AccountId) -> Balance;
fn pool_needs_delegate_migration(pool_id: PoolId) -> bool;
fn member_needs_delegate_migration(member: AccountId) -> bool;
```

## Refactors
- Introduces newtypes for `Agent`, `Delegator`, `Pool` and
`[Pool]Member`. And refactors `StakeAdapter` and `DelegationInterface`
to accept the above types. This will help make these apis typesafe
against using wrong account type.
- Fixing `DelegationInterface` apis to return optional (instead of
default value if key does not exist).
- Rename struct `Agent` that wraps `AgentLedger` to `AgentOuterLedger`
which is clearer (naming wise) and different from the newtype `Agent`.
- Cleaning up new Pool events (related to `Delegation` feature of pool).

+title: Runtime apis to help with delegate-stake based Nomination Pools.
+
+doc:
+  - audience: Runtime User
+    description: |
+      Introduces a new set of runtime apis to facilitate dapps and wallets to integrate with delegate-stake
+      functionalities of Nomination Pools. These apis support pool and member migration, as well as lazy application of
+      pending slashes of the pool members.

Subject: [PATCH 103/106] Revamp the Readme of the minimal template (#4649)

- Addresses
[this](https://github.com/paritytech/polkadot-sdk/issues/3155#issuecomment-2126934939).
- Technical content got adopted from the existing [solochain
readme](https://github.com/paritytech/polkadot-sdk/tree/master/templates/solochain).
  - Updated some broken links there.
- The docker instructions will work after
https://github.com/paritytech/polkadot-sdk/pull/4637.
- See the [rendered
version](https://github.com/paritytech/polkadot-sdk/blob/rzadp/minimal-template-readme/templates/minimal/README.md).

-You can generate and view the [Rust
-Docs](https://doc.rust-lang.org/cargo/commands/cargo-doc.html) for this template
-with this command:
+> This is a minimal template for creating a blockchain based on Polkadot SDK.
+> 
+> This template is automatically updated after releases in the main [Polkadot SDK monorepo](https://github.com/paritytech/polkadot-sdk).
+
+</div>
+
+🤏 This template is a minimal (in terms of complexity and the number of components) template for building a blockchain node.
+
+🔧 It's runtime is configured of a single custom pallet as a staring point, and a handful of ready-made pallets such as a [Balances pallet](https://paritytech.github.io/polkadot-sdk/master/pallet_balances/index.html).
+
+👤 The template has no consensus configured - it is best for experimenting with a single node network.
+
+## Template Structure
+
+A Polkadot SDK based project such as this one consists of:
+
+- 💿 a [Node](./node/README.md) - the binary application.
+- 🧮 the [Runtime](./runtime/README.md) - the core logic of the blockchain.
+- 🎨 the [Pallets](./pallets/README.md) - from which the runtime is constructed.
+
+## Getting Started
+
+🦀 The template is using the Rust language.
+
+👉 Check the
+[Rust installation instructions](https://www.rust-lang.org/tools/install) for your system.
+
+🛠️ Depending on your operating system and Rust version, there might be additional
+packages required to compile this template - please take note of the Rust compiler output.
+
+### Build
+
+🔨 Use the following command to build the node without launching it:
 
 ```sh
-cargo doc -p minimal-template --open
+cargo build --release
 ```
+
+🐳 Alternatively, build the docker image:
+
+```sh
+docker build . -t polkadot-sdk-minimal-template
+```
+
+### Single-Node Development Chain
+
+👤 The following command starts a single-node development chain:
+
+```sh
+./target/release/minimal-template-node --dev
+
+# docker version:
+docker run --rm polkadot-sdk-minimal-template --dev
+```
+
+Development chains:
+
+- 🧹 Do not persist the state.
+- 💰 Are preconfigured with a genesis state that includes several prefunded development accounts.
+- 🧑‍⚖️ Development accounts are used as `sudo` accounts.
+
+### Connect with the Polkadot-JS Apps Front-End
+
+🌐 You can interact with your local node using the
+hosted version of the [Polkadot/Substrate
+Portal](https://polkadot.js.org/apps/#/explorer?rpc=ws://localhost:9944).
+
+🪐 A hosted version is also
+available on [IPFS](https://dotapps.io/).
+
+🧑‍🔧 You can also find the source code and instructions for hosting your own instance in the
+[`polkadot-js/apps`](https://github.com/polkadot-js/apps) repository.
+
+## Contributing
+
+🔄 This template is automatically updated after releases in the main [Polkadot SDK monorepo](https://github.com/paritytech/polkadot-sdk).
+
+➡️ Any pull requests should be directed to this [source](https://github.com/paritytech/polkadot-sdk/tree/master/templates/minimal).

+
+## Getting Help
+
+🧑‍🏫 To learn about Polkadot in general, [Polkadot.network](https://polkadot.network/) website is a good starting point.
+
+🧑‍🔧 For technical introduction, [here](https://github.com/paritytech/polkadot-sdk#-documentation) are the Polkadot SDK documentation resources.

+# Node
+
+ℹ️ A node -  in Polkadot - is a binary executable, whose primary purpose is to execute the [runtime](../runtime/README.md).
+
+🔗 It communicates with other nodes in the network, and aims for [consensus](https://wiki.polkadot.network/docs/learn-consensus) among them.
+
+⚙️ It acts as a remote procedure call (RPC) server, allowing interaction with the blockchain.

+👇 Here are the most important files in this node template:
+
+- [`chain_spec.rs`](./src/chain_spec.rs): A chain specification is a source code file that defines the chain's initial (genesis) state.
+- [`service.rs`](./src/service.rs): This file defines the node implementation. It's a place to configure consensus-related topics. In favor of minimalism, this template has no consensus configured.
