## Changes

This MR refactores the XCMP, Parachains System and DMP pallets to use
the [MessageQueue](https://github.com/paritytech/substrate/pull/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.

TODO:
- [x] Remove c&p code after
https://github.com/paritytech/polkadot/pull/6271
- [x] Use `HandleMessage` once it is public in Substrate
- [x] fix `runtime-benchmarks` feature
https://github.com/paritytech/polkadot/pull/6966
- [x] Benchmarks
- [x] Tests
- [ ] Migrate `InboundXcmpStatus` to `InboundXcmpSuspended`
- [x] Possibly cleanup Migrations (DMP+XCMP)
- [x] optional: create `TransformProcessMessageOrigin` in Substrate and
replace `ProcessFromSibling`
- [ ] Rerun weights on ref HW

## Summary

Asset bridging support for AssetHub**Rococo** <-> AssetHub**Wococo** was
added [here](https://github.com/paritytech/polkadot-sdk/pull/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
https://github.com/paritytech/polkadot-sdk/issues/1988.

## TODO

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

Removed confusing and outdated `TODO`.

This ensures that upgrading a parachain code sends the same event &
digest as when using `set_code` on a standalone chain.

Close: https://github.com/paritytech/polkadot-sdk/issues/2049

Closes https://github.com/paritytech/release-engineering/issues/6

Adds a new Github Workflow which on a new release being created, builds
and attaches all runtimes managed in this repository in two flavours:
- `dev-debug-build`: Built with the `try-runtime` feature and has
logging enabled
- `on-chain-release`: Built with the regular old `on-chain-release`
feature

The new Github Workflow could be extended in the future by the
@paritytech/release-engineering team to fully automate the release
process if they choose to, similar to how it is fully automated in the
Fellowship repo
(https://github.com/polkadot-fellows/runtimes/blob/main/.github/workflows/release.yml).

The `on-chain-release` did not exist for parachains, so I added it.

When warp syncing a node we import a header of the parachain around the
tip of the chain. This header is currently not imported as finalized
block (should be fixed at some point as well), the parent headers are
not yet present (still being synced) and thus, we run into a panic. Even
if there is a case where a leaf could not be found in the database, this
probably means that the db is broken and it will fail somewhere elese.

the min slot duration should be 0 only if the `experimental` feature is
enabled. otherwise, the runtime will panic on a division by 0.

# Description

- What does this PR do?

While working with `pallet_nfts` through `nonfungibles_v2` traits
`Inspect, Mutate`, I found out that once you have set the collection
attribute with `<Nfts as Mutate>::set_collection_attribute()`, it's not
possible to read it with `<Nfts as Inspect>::collection_attribute()`
since they use different `namespace` values. When setting the attribute,
`AttributeNamespace::Pallet` is used, while
`AttributeNamespace::CollectionOwner` is used when reading.

more context:
https://github.com/freeverseio/laos/issues/7#issuecomment-1766137370

This PR makes `item` an optional parameter in
`Inspect::system_attribute()`, to be able to read collection attributes.

- Why are these changes needed?

To be able to read collection level attributes when reading attributes
of the collection. It will be possible to read collection attributes by
passing `None` for `item`

- How were these changes implemented and what do they affect?

`NftsApi` is also affected and `NftsApi::system_attribute()` now accepts
optional `item` parameter.

## Breaking change

Because of the change in the `NftsApi::system_attribute()` method's
`item` param, parachains who integrated the `NftsApi` need to update
their API code and frontend integrations accordingly. AssetHubs are
unaffected since the NftsApi wasn't released on those parachains yet.

[testnet] Align testnet system parachain runtimes using `RelayTreasuryLocation` and `SystemParachains` in the same way (#2023)

This PR addresses several issues:
- simplify referencing `RelayTreasuryLocation` without needing
additional `RelayTreasury` struct
- fix for referencing `SystemParachains` from parachain with `parents:
1` instead of `parents: 0`
- removed hard-coded constants and fix tests for `asset-hub-rococo`
which was merged to master after
https://github.com/paritytech/polkadot-sdk/pull/1726

## Breaking Changes

This PR introduces a new item to `pallet_balances::Config`:

```diff
trait Config {
++    type RuntimeFreezeReasons;
}
```

This value is only used to check it against `type MaxFreeze`. A similar
check has been added for `MaxHolds` against `RuntimeHoldReasons`, which
is already given to `pallet_balances`.

In all contexts, you should pass the real `RuntimeFreezeReasons`
generated by `construct_runtime` to `type RuntimeFreezeReasons`. Passing
`()` would also work, but it would imply that the runtime uses no
freezes at all.

Fixes #768.

This PR does not introduce any functional changes to the existing code,
it merely addresses several minor refactors:
- Moving bridging pallets to separate files.
- Improving the readability and naming of weight files for bridging
pallets and bridging pallet instances.

The reason for this refactor is to facilitate easier plugin integration
for the upcoming bridge between Rococo and Westend.

This PR addresses several minor issues:
- Fixes the symlink for `asset-hub-rococo.json` chainspec.
- Corrects the `asset-hub-rococo-genesis` invulnerables setup.
- Relocates common bash functions for bridge testing to a separate file
`bridges_common.sh`.

The `xcm` crate was renamed to `staging-xcm` to be able to publish it to
crates.io as someone as squatted `xcm`. The problem with this rename is
that the `TypeInfo` includes the crate name which ultimately lands in
the metadata. The metadata is consumed by downstream users like
`polkadot-js` or people building on top of `polkadot-js`. These people
are using the entire `path` to find the type in the type registry. Thus,
their code would break as the type path would now be [`staging_xcm`,
`VersionedXcm`] instead of [`xcm`, `VersionedXcm`]. This pull request
fixes this by renaming the path segment `staging_xcm` to `xcm`.

This requires: https://github.com/paritytech/scale-info/pull/197

Removed some debug logs

Until now prometheus metrics were not exposed by the minimal relay chain
node.
Also slight cleanups.

When launching our [small
network](https://github.com/paritytech/polkadot-sdk/blob/master/cumulus/zombienet/examples/small_network.toml)
for testing the node was crashing here shortly after launch:

https://github.com/paritytech/polkadot-sdk/blob/5cdd819e/polkadot/node/collation-generation/src/lib.rs#L140

After changes in #1788 for the asset hub collator we are waiting for
blocks of the shell runtime to pass before we initialize aura. However,
this means that we attempted to initialize the collation related relay
chain subsystems twice, leading to the error.

I modified Aura to let it optionally take an already initialized stream
of collation requests.

Combination of paritytech/polkadot#7005, its addon PR
paritytech/polkadot#7585 and its companion paritytech/cumulus#2433.

This PR introduces a new XcmFeesToAccount struct which implements the
`FeeManager` trait, and assigns this struct as the `FeeManager` in the
XCM config for all runtimes.

The struct simply deposits all fees handled by the XCM executor to a
specified account. In all runtimes, the specified account is configured
as the treasury account.

XCM __delivery__ fees are now being introduced (unless the root origin
is sending a message to a system parachain on behalf of the originating
chain).

# Note for reviewers

Most file changes are tests that had to be modified to account for the
new fees.
Main changes are in:
- cumulus/pallets/xcmp-queue/src/lib.rs <- To make it track the delivery
fees exponential factor
- polkadot/xcm/xcm-builder/src/fee_handling.rs <- Added. Has the
FeeManager implementation
- All runtime xcm_config files <- To add the FeeManager to the XCM
configuration

# Important note

After this change, instructions that create and send a new XCM (Query*,
Report*, ExportMessage, InitiateReserveWithdraw, InitiateTeleport,
DepositReserveAsset, TransferReserveAsset, LockAsset and RequestUnlock)
will require the corresponding origin account in the origin register to
pay for transport delivery fees, and the onward message will fail to be
sent if the origin account does not have the required amount. This
delivery fee is on top of what we already collect as tx fees in
pallet-xcm and XCM BuyExecution fees!

Wallet UIs that want to expose the new delivery fee can do so using the
formula:

```
delivery_fee_factor * (base_fee + encoded_msg_len * per_byte_fee)
```

where the delivery fee factor can be obtained from the corresponding
pallet based on which transport you are using (UMP, HRMP or bridges),
the base fee is a constant, the encoded message length from the message
itself and the per byte fee is the same as the configured per byte fee
for txs (i.e. `TransactionByteFee`).

Co-authored-by: Liam Aharon <[email protected]>

## Summary

This PR introduces several enhancements.

The current implementation of `NetworkExportTable` lacks remote location
filtering support beyond `NetworkId` lookup. To provide more control and
granularity, it's essential to allow configuration for bridging to
different consensus `NetworkId` while restricting access e.g. to
particular remote parachains.

Additionally, the `StartsWith` and `Equals` and
`StartsWithExplicitGlobalConsensus` helper functions, which are in
active use, are moved to the `xcm-builder` and `frame_support` modules
for better code organization.

Adds a new `LocationWithAssetFilters` filter to enable location-based
and asset-related filtering. This filter is useful for configuring the
`pallet_xcm` filter for
[XcmTeleportFilter](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/pallet-xcm/src/lib.rs#L212)
and
[XcmReserveTransferFilter](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/pallet-xcm/src/lib.rs#L216)
to restrict specific assets.

Furthermore, the `BridgeMessage` fields are not accessible outside of
`xcm-builder`, limiting the ability to create custom logic dependent on
it.

# Desription

## Summary 

This PR introduces several nits and tweaks to xcm emulator tests for
system parachains.

## Explanation

**Deduplicate `XcmPallet::send(` with root origin code**
- Introduced `send_transact_to_parachain` which could be easily reuse
for scenarios like _governance call from relay chain to parachain_.

**Refactor `send_transact_sudo_from_relay_to_system_para_works`**
- Test covered just one use-case which was moved to the
`do_force_create_asset_from_relay_to_system_para`, so now we can extend
this test with more _governance-like_ senarios.
- Renamed to
`send_transact_as_superuser_from_relay_to_system_para_works`.

**Remove `send_transact_native_from_relay_to_system_para_fails` test**
- This test and/or description is kind of misleading, because system
paras support Native from relay chain by `RelayChainAsNative` with
correct xcm origin.
- It tested only sending on relay chain which should go directly to the
relay chain unit-tests (does not even need to be in xcm emulator level).

## Future directions

Check restructure parachains integration tests
[issue](https://github.com/paritytech/polkadot-sdk/issues/1389) and [PR
with more TODOs](https://github.com/paritytech/polkadot-sdk/pull/1693).

[xcm] Use `Weight::MAX` for `reserve_asset_deposited`, `receive_teleported_asset` benchmarks (#1726)

# Description

## Summary

Previously, the `pallet_xcm::do_reserve_transfer_assets` and
`pallet_xcm::do_teleport_assets` functions relied on weight estimation
for remote chain execution, which was based on guesswork derived from
the local chain. This approach led to complications for runtimes that
did not provide or support specific [XCM
configurations](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76/polkadot/xcm/xcm-executor/src/config.rs#L43-L47)
for `IsReserve` or `IsTeleporter`. Consequently, such runtimes had to
resort to implementing hard-coded weights for XCM instructions like
`reserve_asset_deposited` or `receive_teleported_asset` to support
extrinsics such as `pallet_xcm::reserve_transfer_assets` and
`pallet_xcm::teleport_assets`, which depended on remote weight
estimation.

The issue of remote weight estimation was addressed and resolved by
[Pull Request
#1645](https://github.com/paritytech/polkadot-sdk/pull/1645), which
removed the need for remote weight estimation.

## Solution

As a continuation of this improvement, the current PR proposes further
cleanup by removing unnecessary hard-coded values and rectifying
benchmark results with `Weight::MAX` that previously used
`T::BlockWeights::get().max_block` as an override for unsupported XCM
instructions like `ReserveAssetDeposited` and `ReceiveTeleportedAsset`.


## Questions

- [x] Can we remove now also `Hardcoded till the XCM pallet is fixed`
for `deposit_asset`? E.g. for AssetHubKusama
[here](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76/cumulus/parachains/runtimes/assets/asset-hub-kusama/src/weights/xcm/mod.rs#L129-L134)
- [x] Are comments like
[this](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76/polkadot/runtime/kusama/src/weights/xcm/mod.rs#L94)
`// Kusama doesn't support ReserveAssetDeposited, so this benchmark has
a default weight` still relevant? Shouldnt be removed/changed?


## TODO

- [x] `bench bot` regenerate xcm weights for all runtimes
- [x] remove hard-coded stuff from system parachain weight files
- [ ] when merged, open `polkadot-fellow/runtimes` PR

### Summary 

This PR introduces new dispatchables to the treasury pallet, allowing
spends of various asset types. The enhanced features of the treasury
pallet, in conjunction with the asset-rate pallet, are set up and
enabled for Westend and Rococo.

### Westend and Rococo runtimes.

Polkadot/Kusams/Rococo Treasury can accept proposals for `spends` of
various asset kinds by specifying the asset's location and ID.

#### Treasury Instance New Dispatchables:
- `spend(AssetKind, AssetBalance, Beneficiary, Option<ValidFrom>)` -
propose and approve a spend;
- `payout(SpendIndex)` - payout an approved spend or retry a failed
payout
- `check_payment(SpendIndex)` - check the status of a payout;
- `void_spend(SpendIndex)` - void previously approved spend;
> existing spend dispatchable renamed to spend_local

in this context, the `AssetKind` parameter contains the asset's location
and it's corresponding `asset_id`, for example:
`USDT` on `AssetHub`,
``` rust
location = MultiLocation(0, X1(Parachain(1000)))
asset_id = MultiLocation(0, X2(PalletInstance(50), GeneralIndex(1984)))
```

the `Beneficiary` parameter is a `MultiLocation` in the context of the
asset's location, for example
``` rust
// the Fellowship salary pallet's location / account
FellowshipSalaryPallet = MultiLocation(1, X2(Parachain(1001), PalletInstance(64)))
// or custom `AccountId`
Alice = MultiLocation(0, AccountId32(network: None, id: [1,...]))
```

the `AssetBalance` represents the amount of the `AssetKind` to be
transferred to the `Beneficiary`. For permission checks, the asset
amount is converted to the native amount and compared against the
maximum spendable amount determined by the commanding spend origin.

the `spend` dispatchable allows for batching spends with different
`ValidFrom` arguments, enabling milestone-based spending. If the
expectations tied to an approved spend are not met, it is possible to
void the spend later using the `void_spend` dispatchable.

Asset Rate Pallet provides the conversion rate from the `AssetKind` to
the native balance.

#### Asset Rate Instance Dispatchables:
- `create(AssetKind, Rate)` - initialize a conversion rate to the native
balance for the given asset
- `update(AssetKind, Rate)` - update the conversion rate to the native
balance for the given asset
- `remove(AssetKind)` - remove an existing conversion rate to the native
balance for the given asset

the pallet's dispatchables can be executed by the Root or Treasurer
origins.

### Treasury Pallet

Treasury Pallet can accept proposals for `spends` of various asset kinds
and pay them out through the implementation of the `Pay` trait.

New Dispatchables:
- `spend(Config::AssetKind, AssetBalance, Config::Beneficiary,
Option<ValidFrom>)` - propose and approve a spend;
- `payout(SpendIndex)` - payout an approved spend or retry a failed
payout;
- `check_payment(SpendIndex)` - check the status of a payout;
- `void_spend(SpendIndex)` - void previously approved spend;
> existing spend dispatchable renamed to spend_local

The parameters' types of the `spend` dispatchable exposed via the
pallet's `Config` and allows to propose and accept a spend of a certain
amount.

An approved spend can be claimed via the `payout` within the
`Config::SpendPeriod`. Clients provide an implementation of the `Pay`
trait which can pay an asset of the `AssetKind` to the `Beneficiary` in
`AssetBalance` units.

The implementation of the Pay trait might not have an immediate final
payment status, for example if implemented over `XCM` and the actual
transfer happens on a remote chain.

The `check_status` dispatchable can be executed to update the spend's
payment state and retry the `payout` if the payment has failed.
