# Description

This PR updates the node-template-release generation binary as well as
the `node-template-release.sh` file so that we can automatically push
updates to the [substrate-node-template
repository](https://github.com/substrate-developer-hub/substrate-node-template).
I assume this part was not updated after the substrate project has been
moved into the polkadot-sdk mono repo.

# Adjustments
- extend the `node-template-release.sh` to support the substrate
child-folder
- update the `SUBSTRATE_GIT_URL`
- fix the Cargo.toml filter (so that it does not include any
non-relevant .toml files)
- set the workspace-edition to 2021

# Note
In order to auto-generate the artifacts [this
line](https://github.com/paritytech/polkadot-sdk/blob/master/.gitlab/pipeline/build.yml#L320C15-L320C15)
needs to be included in the build.yml script again. Since I do not have
access to the (probably) internal gitlab environment I hope that someone
with actual access can introduce that change.
I also do not know how the auto-publish feature works so that would be
another thing to add later on.

## Summary

Asset bridging support for AssetHub**Rococo** <-> AssetHub**Wococo** was
added [here](paritytech#1215), so
now we aim to bridge AssetHub**Rococo** and AssetHub**Westend**. (And
perhaps retire AssetHubWococo and the Wococo chains).

## Solution

**bridge-hub-westend-runtime**
- added new runtime as a copy of `bridge-hub-rococo-runtime`
- added support for bridging to `BridgeHubRococo`
- added tests and benchmarks

**bridge-hub-rococo-runtime**
- added support for bridging to `BridgeHubWestend`
- added tests and benchmarks
- internal refactoring by splitting bridge configuration per network,
e.g., `bridge_to_whatevernetwork_config.rs`.

**asset-hub-rococo-runtime**
- added support for asset bridging to `AssetHubWestend` (allows to
receive only WNDs)
- added new xcm router for `Westend`
- added tests and benchmarks

**asset-hub-westend-runtime**
- added support for asset bridging to `AssetHubRococo` (allows to
receive only ROCs)
- added new xcm router for `Rococo`
- added tests and benchmarks

## Deployment

All changes will be deployed as a part of
paritytech#1988.

## TODO

- [x] benchmarks for all pallet instances
- [x] integration tests
- [x] local run scripts

# Description
We derive few useful traits on `ErrorOrigin` and `ExecError`, including
`codec::Encode` and `codec::Decode`, so that `ExecResult` is
en/decodable as well. This is required for a contract mocking feature
(already prepared in drink:
inkdevhub/drink#61). In more detail:
`ExecResult` must be passed from runtime extension, through runtime
interface, back to the pallet, which requires that it is serializable to
bytes in some form (or implements some rare, auxiliary traits).

**Impact on runtime size**: Since most of these traits is used directly
in the pallet now, compiler should be able to throw it out (and thus we
bring no new overhead). However, they are very useful in secondary tools
like drink or other testing libraries.

## Changes

This MR refactores the XCMP, Parachains System and DMP pallets to use
the [MessageQueue](paritytech/substrate#12485)
for delayed execution of incoming messages. The DMP pallet is entirely
replaced by the MQ and thereby removed. This allows for PoV-bounded
execution and resolves a number of issues that stem from the current
work-around.

All System Parachains adopt this change.  
The most important changes are in `primitives/core/src/lib.rs`,
`parachains/common/src/process_xcm_message.rs`,
`pallets/parachain-system/src/lib.rs`, `pallets/xcmp-queue/src/lib.rs`
and the runtime configs.

### DMP Queue Pallet

The pallet got removed and its logic refactored into parachain-system.
Overweight message management can be done directly through the MQ
pallet.

Final undeployment migrations are provided by
`cumulus_pallet_dmp_queue::UndeployDmpQueue` and `DeleteDmpQueue` that
can be configured with an aux config trait like:

```rust
parameter_types! {
	pub const DmpQueuePalletName: &'static str = \"DmpQueue\" < CHANGE ME;
	pub const RelayOrigin: AggregateMessageOrigin = AggregateMessageOrigin::Parent;
}

impl cumulus_pallet_dmp_queue::MigrationConfig for Runtime {
	type PalletName = DmpQueuePalletName;
	type DmpHandler = frame_support::traits::EnqueueWithOrigin<MessageQueue, RelayOrigin>;
	type DbWeight = <Runtime as frame_system::Config>::DbWeight;
}

// And adding them to your Migrations tuple:
pub type Migrations = (
	...
	cumulus_pallet_dmp_queue::UndeployDmpQueue<Runtime>,
	cumulus_pallet_dmp_queue::DeleteDmpQueue<Runtime>,
);
```

### XCMP Queue pallet

Removed all dispatch queue functionality. Incoming XCMP messages are now
either: Immediately handled if they are Signals, enqueued into the MQ
pallet otherwise.

New config items for the XCMP queue pallet:
```rust
/// The actual queue implementation that retains the messages for later processing.
type XcmpQueue: EnqueueMessage<ParaId>;

/// How a XCM over HRMP from a sibling parachain should be processed.
type XcmpProcessor: ProcessMessage<Origin = ParaId>;

/// The maximal number of suspended XCMP channels at the same time.
#[pallet::constant]
type MaxInboundSuspended: Get<u32>;
```

How to configure those:

```rust
// Use the MessageQueue pallet to store messages for later processing. The `TransformOrigin` is needed since
// the MQ pallet itself operators on `AggregateMessageOrigin` but we want to enqueue `ParaId`s.
type XcmpQueue = TransformOrigin<MessageQueue, AggregateMessageOrigin, ParaId, ParaIdToSibling>;

// Process XCMP messages from siblings. This is type-safe to only accept `ParaId`s. They will be dispatched
// with origin `Junction::Sibling(…)`.
type XcmpProcessor = ProcessFromSibling<
	ProcessXcmMessage<
		AggregateMessageOrigin,
		xcm_executor::XcmExecutor<xcm_config::XcmConfig>,
		RuntimeCall,
	>,
>;

// Not really important what to choose here. Just something larger than the maximal number of channels.
type MaxInboundSuspended = sp_core::ConstU32<1_000>;
```

The `InboundXcmpStatus` storage item was replaced by
`InboundXcmpSuspended` since it now only tracks inbound queue suspension
and no message indices anymore.

Now only sends the most recent channel `Signals`, as all prio ones are
out-dated anyway.

### Parachain System pallet

For `DMP` messages instead of forwarding them to the `DMP` pallet, it
now pushes them to the configured `DmpQueue`. The message processing
which was triggered in `set_validation_data` is now being done by the MQ
pallet `on_initialize`.

XCMP messages are still handed off to the `XcmpMessageHandler`
(XCMP-Queue pallet) - no change here.

New config items for the parachain system pallet:
```rust
/// Queues inbound downward messages for delayed processing. 
///
/// Analogous to the `XcmpQueue` of the XCMP queue pallet.
type DmpQueue: EnqueueMessage<AggregateMessageOrigin>;
``` 

How to configure:
```rust
/// Use the MQ pallet to store DMP messages for delayed processing.
type DmpQueue = MessageQueue;
``` 

## Message Flow

The flow of messages on the parachain side. Messages come in from the
left via the `Validation Data` and finally end up at the `Xcm Executor`
on the right.

## Further changes

- Bumped the default suspension, drop and resume thresholds in
`QueueConfigData::default()`.
- `XcmpQueue::{suspend_xcm_execution, resume_xcm_execution}` errors when
they would be a noop.
- Properly validate the `QueueConfigData` before setting it.
- Marked weight files as auto-generated so they wont auto-expand in the
MR files view.
- Move the `hypothetical` asserts to `frame_support` under the name
`experimental_hypothetically`

Questions:
- [ ] What about the ugly `#[cfg(feature = \"runtime-benchmarks\")]` in
the runtimes? Not sure how to best fix. Just having them like this makes
tests fail that rely on the real message processor when the feature is
enabled.
- [ ] Need a good weight for `MessageQueueServiceWeight`. The scheduler
already takes 80% so I put it to 10% but that is quite low.

The `BlockBuilderProvider` was a trait that was defined in
`sc-block-builder`. The trait was implemented for `Client`. This
basically meant that you needed to import `sc-block-builder` any way to
have access to the block builder. So, this trait was not providing any
real value. This pull request is removing the said trait. Instead of the
trait it introduces a builder for creating a `BlockBuilder`. The builder
currently has the quite fabulous name `BlockBuilderBuilder` (I'm open to
any better name 😅). The rest of the pull request is about
replacing the old trait with the new builder.

# Downstream code changes

If you used `new_block` or `new_block_at` before you now need to switch
it over to the new `BlockBuilderBuilder` pattern:

```rust
// `new` requires a type that implements `CallApiAt`. 
let mut block_builder = BlockBuilderBuilder::new(client)
                // Then you need to specify the hash of the parent block the block will be build on top of
		.on_parent_block(at)
                // The block builder also needs the block number of the parent block. 
                // Here it is fetched from the given `client` using the `HeaderBackend`
                // However, there also exists `with_parent_block_number` for directly passing the number
		.fetch_parent_block_number(client)
		.unwrap()
                // Enable proof recording if required. This call is optional.
		.enable_proof_recording()
                // Pass the digests. This call is optional.
                .with_inherent_digests(digests)
		.build()
		.expect("Creates new block builder");

> ensure through proper configuration that the new byte-based deposit is

Not sure this is needed anymore. If the new deposits are higher than
what is currently on chain and users don't have enough funds to reserve
what is needed, the extrinisc fails and they're basically grandfathered
and frozen until they add more funds and/or make a change to their
identity. This behavior seems fine to me. Original idea
[here](paritytech#1661 (comment)).

> add an extrinsic to rejig deposits to account for the change above

This was initially implemented but now removed from this PR in favor of
the implementation detailed
[here](paritytech#2088).

Instead of issuing/importing one tranche0 assignment per candidate,

However, we will not be sending out the new assignment certificates,
yet. So everything should work exactly as before. Once the majority of

enable the new certificates (starting at a specific relay chain block)
with a new client update.

Add infrastructure needed to have a Pallet::decode_entire_state(), which
makes sure all "typed" storage items defined in the pallet are
decode-able.

This is not enforced in any way at the moment. Teams who wish to

frame_support::storage::migration::EnsureStateDecodes as the LAST ITEM
of the runtime's custom migrations, and pass it to frame-executive. This
will make it usable in try-runtime on-runtime-upgrade.

This now catches cases like

```pre

### Problem
Quoting from the above issue:

> When adding a pallet to chain after genesis we currently don't set the
StorageVersion. So, when calling on_chain_storage_version it returns 0
while the pallet is maybe already at storage version 9 when it was added
to the chain. This could lead to issues when running migrations.

### Solution

- Create a new trait `BeforeAllRuntimeMigrations` with a single method
`fn before_all_runtime_migrations() -> Weight` trait with a noop default
implementation
- Modify `Executive` to call
`BeforeAllRuntimeMigrations::before_all_runtime_migrations` for all
pallets before running any other hooks
- Implement `BeforeAllRuntimeMigrations` in the pallet proc macro to
initialize the on-chain version to the current pallet version if the
pallet has no storage set (indicating it has been recently added to the
runtime and needs to have its version initialised).

### Other changes in this PR

- Abstracted repeated boilerplate to access the `pallet_name` in the
pallet expand proc macro.

### FAQ

#### Why create a new hook instead of adding this logic to the pallet
`pre_upgrade`?

`Executive` currently runs `COnRuntimeUpgrade` (custom migrations)
before `AllPalletsWithSystem` migrations. We need versions to be
initialized before the `COnRuntimeUpgrade` migrations are run, because
`COnRuntimeUpgrade` migrations may use the on-chain version for critical
logic. e.g. `VersionedRuntimeUpgrade` uses it to decide whether or not
to execute.

We cannot reorder `COnRuntimeUpgrade` and `AllPalletsWithSystem` so
`AllPalletsWithSystem` runs first, because `AllPalletsWithSystem` have
some logic in their `post_upgrade` hooks to verify that the on-chain
version and current pallet version match. A common use case of
`COnRuntimeUpgrade` migrations is to perform a migration which will
result in the versions matching, so if they were reordered these
`post_upgrade` checks would fail.

#### Why init the on-chain version for pallets without a current storage
version?

We must init the on-chain version for pallets even if they don't have a
defined storage version so if there is a future version bump, the
on-chain version is not automatically set to that new version without a
proper migration.

e.g. bad scenario:

1. A pallet with no 'current version' is added to the runtime
2. Later, the pallet is upgraded with the 'current version' getting set
to 1 and a migration is added to Executive Migrations to migrate the
storage from 0 to 1
    a. Runtime upgrade occurs
    b. `before_all` hook initializes the on-chain version to 1
c. `on_runtime_upgrade` of the migration executes, and sees the on-chain
version is already 1 therefore think storage is already migrated and
does not execute the storage migration
Now, on-chain version is 1 but storage is still at version 0.

By always initializing the on-chain version when the pallet is added to
the runtime we avoid that scenario.

…itytech#2202)

When running with `--relay-chain-rpc-url` we received multiple reports
of high traffic that disappears when `--in-peers-light 0` is set. Indeed
it does not make much sense for light clients to connect to the minimal
node since it is not running the block announce protocol and the
request/response protocol for light clients.

This is intended to alleviate the traffic issues for now.

Added a proc macro to be able to write XCMs using the builder pattern.
This means we go from having to do this:

```rust
let message: Xcm<()> = Xcm(vec![
  WithdrawAsset(assets),
  BuyExecution { fees: asset, weight_limit: Unlimited },
  DepositAsset { assets, beneficiary },
]);
```

to this:

```rust
let message: Xcm<()> = Xcm::builder()
  .withdraw_asset(assets)
  .buy_execution(asset, Unlimited),
  .deposit_asset(assets, beneficiary)
  .build();
```

The trie cache implementation was ignoring the `storage_root` when
setting up the value cache. The problem with this is that the value
cache works using `storage_keys` and these keys are not unique across
different tries. A block can actually have different tries (main trie
and multiple child tries). This pull request fixes the issue by not
ignoring the `storage_root` and returning an unique `value_cache` per
`storage_root`. It also adds a test for the seen bug and improves
documentation that this doesn't happen again.

Genesis building in runtime may involve calling some custom host
functions. This PR allows to pass `HostFunctions` into the `ChainSpec`
struct, which in turn are passed to `WasmExecutor`. The `ChainSpec` now
has extended host functions type parameter:
```
pub struct ChainSpec<G, E = NoExtension, EHF = ()>
```
which will be combined with the default set
(`sp_io::SubstrateHostFunctions`) in an instance of `WasmExecutor` used
to build the genesis config.

This PR contains some fixes and cleanups for parachain nodes:

1. When using async backing, node no longer complains about being unable
to reach the prospective-parachain subsystem.
2. Parachain warp sync now informs users that the finalized para block
has been retrieved.
```
2023-11-08 13:24:42 [Parachain] 🎉 Received finalized parachain header #5747719 (0xa0aa…674b) from the relay chain.
```
3. When a user supplied an invalid `--relay-chain-rpc-url`, we were
crashing with a very verbose message. Removed the `expect` and improved
the error message.
```
2023-11-08 13:57:56 [Parachain] No valid RPC url found. Stopping RPC worker.

the QueryPallet instruction in a meaningful way since they couldn't read
the received data.

This PR changes the registration order of the `MessageQueue` pallet so
that it is registered last.

This is necessary so that the
[on_initialize](https://github.com/Snowfork/snowbridge/blob/df8d5da82e517a65fb0858a4f2ead533290336b5/parachain/pallets/outbound-queue/src/lib.rs#L267)
hooks for Snowbridge can run before `MessageQueue` delivers messages
using its own `on_initialize`.

Generally, I think this is preferable regardless of Snowbridge's
particular requirements. Other pallets may want to do housekeeping
before MessageQueue starts delivering messages.

I'm hoping this PR, if accepted, can be included in the same release as
paritytech#1246. As otherwise,
changing the order of pallet registration is an ABI-breaking change.

One for local networks with `fast-runtime` feature activated (1 minute
sessions) and one without the feature activated that will be the default
that runs with 1 hour long sessions.

We are introducing a new set of `XcmController` traits (final name yet
to be determined).
These traits are implemented by `pallet-xcm` and allows other pallets,
such as `pallet_contracts`, to rely on these traits instead of tight
coupling them to `pallet-xcm`.

Using only the existing Xcm traits would mean duplicating the logic from
`pallet-xcm` in these other pallets, which we aim to avoid. Our
objective is to ensure that when these APIs are called from
`pallet-contracts`, they produce the exact same outcomes as if called
directly from `pallet-xcm`.

The other benefits is that we can also expose return values to
`pallet-contracts` instead of just calling `pallet-xcm` dispatchable and
getting a `DispatchResult` back.

See traits integration in this PR
paritytech#1248, where the traits
are used as follow to define and implement `pallet-contracts` Config.
```rs
// Contracts config:
pub trait Config: frame_system::Config {
  // ...

  /// A type that exposes XCM APIs, allowing contracts to interact with other parachains, and
  /// execute XCM programs.
  type Xcm: xcm_executor::traits::Controller<
	  OriginFor<Self>,
	  <Self as frame_system::Config>::RuntimeCall,
	  BlockNumberFor<Self>,
  >;
}

// implementation
impl pallet_contracts::Config for Runtime {
        // ...

	type Xcm = pallet_xcm::Pallet<Self>;
}

Fixes paritytech#1725

This PR adds the following changes:
1. An attribute `pallet::feeless_if` that can be optionally attached to
a call like so:
```rust
#[pallet::feeless_if(|_origin: &OriginFor<T>, something: &u32| -> bool {
	*something == 0
})]
pub fn do_something(origin: OriginFor<T>, something: u32) -> DispatchResult {
     ....
}
```
The closure passed accepts references to arguments as specified in the
call fn. It returns a boolean that denotes the conditions required for
this call to be "feeless".

2. A signed extension `SkipCheckIfFeeless<T: SignedExtension>` that
wraps a transaction payment processor such as
`pallet_transaction_payment::ChargeTransactionPayment`. It checks for
all calls annotated with `pallet::feeless_if` to see if the conditions
are met. If so, the wrapped signed extension is not called, essentially
making the call feeless.

In order to use this, you can simply replace your existing signed
extension that manages transaction payment like so:
```diff
- pallet_transaction_payment::ChargeTransactionPayment<Runtime>,
+ pallet_skip_feeless_payment::SkipCheckIfFeeless<
+	Runtime,
+	pallet_transaction_payment::ChargeTransactionPayment<Runtime>,
+ >,
```

…extension (paritytech#2294)

…ves (paritytech#1672)

## Motivation

`pallet-xcm` is the main user-facing interface for XCM functionality,
including assets manipulation functions like `teleportAssets()` and
`reserve_transfer_assets()` calls.

While `teleportAsset()` works both ways, `reserve_transfer_assets()`
works only for sending reserve-based assets to a remote destination and
beneficiary when the reserve is the _local chain_.

## Solution

This PR enhances `pallet_xcm::(limited_)reserve_withdraw_assets` to
support transfers when reserves are other chains.
This will allow complete, **bi-directional** reserve-based asset
transfers user stories using `pallet-xcm`.

Enables following scenarios:
- transferring assets with local reserve (was previously supported iff
asset used as fee also had local reserve - now it works in all cases),
- transferring assets with reserve on destination,
- transferring assets with reserve on remote/third-party chain (iff
assets and fees have same remote reserve),
- transferring assets with reserve different than the reserve of the
asset to be used as fees - meaning can be used to transfer random asset
with local/dest reserve while using DOT for fees on all involved chains,
even if DOT local/dest reserve doesn't match asset reserve,
- transferring assets with any type of local/dest reserve while using
fees which can be teleported between involved chains.

All of the above is done by pallet inner logic without the user having
to specify which scenario/reserves/teleports/etc. The correct scenario
and corresponding XCM programs are identified, and respectively, built
automatically based on runtime configuration of trusted teleporters and
trusted reserves.

#### Current limitations:
- while `fees` and "non-fee" `assets` CAN have different reserves (or
fees CAN be teleported), the remaining "non-fee" `assets` CANNOT, among
themselves, have different reserve locations (this is also implicitly
enforced by `MAX_ASSETS_FOR_TRANSFER=2`, but this can be safely
increased in the future).
- `fees` and "non-fee" `assets` CANNOT have **different remote**
reserves (this could also be supported in the future, but adds even more
complexity while possibly not being worth it - we'll see what the future
holds).

BEEFY ECDSA signatures are on keccak has of the messages. As such we can
not simply call

`EcdsaBlsPair::verify(signature.as_inner_ref(), msg,
self.as_inner_ref())`

because that invokes ecdsa default verification which perfoms blake2
hash which we don't want.

This bring up the second issue makes: This makes `sign` and `verify`
function in `pair_crypto` useless, at least for BEEFY use case.
Moreover, there is no obvious clean way to generate the signature given
that pair_crypto does not exposes `sign_prehashed`. You could in theory
query the keystore for the pair (could you?), invoke `to_raw` and
re-generate each sub-pair and sign using each. But that sounds extremely
anticlimactic and will be frow upon by auditors . So I appreciate any
alternative suggestion.

…em` dependency version (paritytech#2288)

## Problem/Motivation
The benchmark for the `ExpectPallet` XCM instruction uses a hard-coded
version `4.0.0` for the `frame_system` pallet. Unfortunately, this
doesn't work for the `polkadot-fellows/runtimes` repository, where we
use dependencies from `crates.io`, e.g.,
[frame-system::23.0.0.0](https://github.com/polkadot-fellows/runtimes/blob/dd7f86f0d50064481ed0b7c0218494a5cfad997e/relay/kusama/Cargo.toml#L83).

Closes: paritytech#2284 

## Solution
This PR fixes the benchmarks that require pallet information and enables
the runtime to provide the correct/custom pallet information. The
default implementation provides `frame_system::Pallet` with index `0`,
where the version is not hard-coded but read from the runtime.


## Local testing

Added log for `T::valid_pallet` to the benchmarks like:
```
let valid_pallet = T::valid_pallet();
log::info!(
	target: "frame::benchmark::pallet",
	"valid_pallet: {}::{}::{}::{}::{}",
	valid_pallet.index,
	valid_pallet.module_name,
	valid_pallet.crate_version.major,
	valid_pallet.crate_version.minor,
	valid_pallet.crate_version.patch,
);
```

Run benchmarks for `westend`:
```
cargo run --bin=polkadot --features=runtime-benchmarks -- benchmark pallet --steps=2 --repeat=1 --extrinsic=* --heap-pages=4096 --json-file=./bench.json --chain=westend-dev --template=./polkadot/xcm/pallet-xcm-benchmarks/template.hbs --pallet=pallet_xcm_benchmarks::generic --output=./polkadot/runtime/westend/src/weights/xcm

come, first served mechanism that was in place before.

Key changes:
- added `update_bond` extrinsic to allow registered candidates to adjust
their bonds in order to dynamically control their bids
- added `take_candidate_slot` extrinsic to try to replace an already
existing candidate by bidding more than them
- candidates are now kept in a sorted list in the pallet storage, where
the top `DesiredCandidates` out of `MaxCandidates` candidates in the
list will be selected by the session pallet as collators
- if the candidacy bond is increased through a `set_candidacy_bond`
call, candidates which don't meet the new bond requirements are kicked

Remove the genesis hash from tests:
- Clippy was passing on the PR:
paritytech#2296
- Clippy fails on master:
https://gitlab.parity.io/parity/mirrors/polkadot-sdk/-/jobs/4328487

This was a race with merging:
paritytech#2295, which introduced
another test that used the `CHAIN_GENESIS`
