      Add HRMP notification handlers to the xcm-executor (#3696) · 8b3bf39a
      Juan Ignacio Rios authored
      Currently the xcm-executor returns an `Unimplemented` error if it
      receives any HRMP-related instruction.
      What I propose here, which is what we are currently doing in our forked
      executor at polimec, is to introduce a trait implemented by the executor
      which will handle those instructions.
      
      This way, if parachains want to keep the default behavior, they just use
      `()` and it will return unimplemented, but they can also implement their
      own logic to establish HRMP channels with other chains in an automated
      fashion, without requiring to go through governance.
      
      Our implementation is mentioned in the [polkadot HRMP
      docs](https://arc.net/l/quote/hduiivbu
      
      ), and it was suggested to us to
      submit a PR to add these changes to polkadot-sdk.

      XCMv4 (#1230) · 8428f678
      Francisco Aguirre authored
      
      
      # Note for reviewer
      
      Most changes are just syntax changes necessary for the new version.
      Most important files should be the ones under the `xcm` folder.
      
      # Description 
      
      Added XCMv4.
      
      ## Removed `Multi` prefix
      The following types have been renamed:
      - MultiLocation -> Location
      - MultiAsset -> Asset
      - MultiAssets -> Assets
      - InteriorMultiLocation -> InteriorLocation
      - MultiAssetFilter -> AssetFilter
      - VersionedMultiAsset -> VersionedAsset
      - WildMultiAsset -> WildAsset
      - VersionedMultiLocation -> VersionedLocation
      
      In order to fix a name conflict, the `Assets` in `xcm-executor` were
      renamed to `HoldingAssets`, as they represent assets in holding.
      
      ## Removed `Abstract` asset id
      
      It was not being used anywhere and this simplifies the code.
      
      Now assets are just constructed as follows:
      
      ```rust
      let asset: Asset = (AssetId(Location::new(1, Here)), 100u128).into();
      ```
      
      No need for specifying `Concrete` anymore.
      
      ## Outcome is now a named fields struct
      
      Instead of
      
      ```rust
      pub enum Outcome {
        Complete(Weight),
        Incomplete(Weight, Error),
        Error(Error),
      }
      ```
      
      we now have
      
      ```rust
      pub enum Outcome {
        Complete { used: Weight },
        Incomplete { used: Weight, error: Error },
        Error { error: Error },
      }
      ```
      
      ## Added Reanchorable trait
      
      Now both locations and assets implement this trait, making it easier to
      reanchor both.
      
      ## New syntax for building locations and junctions
      
      Now junctions are built using the following methods:
      
      ```rust
      let location = Location {
          parents: 1,
          interior: [Parachain(1000), PalletInstance(50), GeneralIndex(1984)].into()
      };
      ```
      
      or
      
      ```rust
      let location = Location::new(1, [Parachain(1000), PalletInstance(50), GeneralIndex(1984)]);
      ```
      
      And they are matched like so:
      
      ```rust
      match location.unpack() {
        (1, [Parachain(id)]) => ...
        (0, Here) => ...,
        (1, [_]) => ...,
      }
      ```
      
      This syntax is mandatory in v4, and has been also implemented for v2 and
      v3 for easier migration.
      
      This was needed to make all sizes smaller.
      
      # TODO
      - [x] Scaffold v4
      - [x] Port github.com/paritytech/polkadot/pull/7236
      - [x] Remove `Multi` prefix
      - [x] Remove `Abstract` asset id

      Add Rococo People <> Rococo Bulletin bridge support to Rococo Bridge Hub (#2540) · 097308e3
      Svyatoslav Nikolsky authored
      This PR adds [Rococo
      People](https://github.com/paritytech/polkadot-sdk/pull/2281) <> [Rococo
      Bulletin](https://github.com/zdave-parity/polkadot-bulletin-chain) to
      the Rococo Bridge Hub code. There's a couple of things left to do here:
      - [x] add remaining tests - it'd need some refactoring in the
      `bridge-hub-test-utils` - will do in a separate PR;
      - [x] actually run benchmarks for new messaging pallet (do we have bot
      nowadays?).
      
      The reason why I'm opening it before this ^^^ is ready, is that I'd like
      to hear others opinion on how to deal with hacks with that bridge.
      Initially I was assuming that Rococo Bulletin will be the 1:1 copy of
      the Polkadot Bulletin (to avoid maintaining multiple
      runtimes/releases/...), so you can see many `PolkadotBulletin` mentions
      in this PR, even though we are going to bridge with the parallel chain
      (`RococoBulletin`). That's because e.g. pallet names from
      `construct_runtime` are affecting runtime storage keys and bridges are
      using runtime storage proofs => it is important to use names that the
      Bulletin chain expects.
      
      But in the end, this hack won't work - we can't use Polkadot Bulletin
      runtime to bridge with Rococo Bridge Hub, because Polkadot Bulletin
      expects Polkadot Bridge hub to use `1002` parachain id and Rococo Bridge
      Hub seats on the `1013`. This also affects storage keys using in
      bridging, so I had to add the [`rococo`
      feature](https://github.com/svyatonik/polkadot-bulletin-chain/blob/add-bridge-pallets/runtime/Cargo.toml#L198)
      to the Bulletin chain. So now we can actually alter its runtime and
      adapt it for Rococo.
      
      So the question here is - what's better for us here
      - to leave everything as is (seems hacky and non-trivial);
      - change Bulletin chain runtime when `rococo` feature is used - e.g. use
      proper names there (`WithPolkadotGrandpa` -> `WithRococoGrandpa`, ...)
      - add another set of pallets to the Bulletin chain runtime to bridge
      with Rococo and never use them in production. Similar to hack that we
      had in Rococo/Wococo
      
      cc @acatangiu @bkontur @serban300 
      
      also cc @joepetrowski
      
       as the main "client" of this bridge
      
      ---
      
      A couple words on how this bridge is different from the Rococo <>
      Westend bridge:
      - it is a bridge with a chain that uses GRANDPA finality, not the
      parachain finality (hence the tests needs to be changed);
      - it is a fee-free bridge. So
      `AllowExplicitUnpaidExecutionFrom<Equals<SiblingPeople>>` + we are not
      paying any rewards to relayers (apart from compensating transaction
      costs).

      Add FungibleAdapter (#2684) · 10a91f82
      Francisco Aguirre authored
      In the move from the old `Currency` traits to the new `fungible/s`
      family of traits, we already had the `FungiblesAdapter` and
      `NonFungiblesAdapter` for multiple fungible and non fungible assets
      respectively. However, for handling only one fungible asset, we were
      missing a `FungibleAdapter`, and so used the old `CurrencyAdapter`
      instead. This PR aims to fill in that gap, and provide the new adapter
      for more updated examples.
      
      I marked the old `CurrencyAdapter` as deprecated as part of this PR, and
      I'll change it to the new `FungibleAdapter` in a following PR.
      The two stages are separated so as to not bloat this PR with some name
      fixes in tests.

      pallet-xcm: enhance `reserve_transfer_assets` to support remote reserves (#1672) · 18257373
      Adrian Catangiu authored
      ## 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).

      Use `Message Queue` as DMP and XCMP dispatch queue (#1246) · e1c033eb
      Oliver Tale-Yazdi authored
      (imported from https://github.com/paritytech/cumulus/pull/2157)
      
      ## 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.

      (1)](https://github.com/paritytech/cumulus/assets/10380170/6cf8b377-88c9-4aed-96df-baace266e04d)
      
      ## 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

      - [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

      [testnet] BridgeHubRococo nits (#1972) · e0620fd9
      Branislav Kontur authored
      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.

      Remove `(rococo/westend)-runtime` deps from testnet AssetHubs (#1979) · c284a931
      Branislav Kontur authored
      ## Problem
      
      This PR addresses the issue with testnet AssetHub builds, which was
      discovered during the execution of `bot bench`.
      
      https://gitlab.parity.io/parity/mirrors/polkadot-sdk/-/jobs/4038738
      ```
           Compiling asset-hub-rococo-runtime-wasm v1.0.0 (/builds/parity/mirrors/polkadot-sdk/target/production/wbuild/asset-hub-rococo-runtime)
        warning: Linking globals named 'Core_version': symbol multiply defined!
        error: failed to load bitcode of module "rococo_runtime-8799ee884447805a.rococo_runtime.0bc572b8-cgu.0.rcgu.o":

      Compiling asset-hub-westend-runtime-wasm v1.0.0 (/builds/parity/mirrors/polkadot-sdk/target/production/wbuild/asset-hub-westend-runtime)

        error: could not compile `asset-hub-westend-runtime-wasm` (lib) due to previous error; 1 warning emitted
      ```
      
      ## Solution
      
      - Removed dependencies on `rococo-runtime` and `westend-runtime`
      introduced by [this
      PR](https://github.com/paritytech/polkadot-sdk/pull/1234/files#diff-a86375df98e04ca3cce1ea35c40257a222e2d5087f5f528ff33307678b78dc2dR534-R550).
      - Replaced `<rococo_runtime::Treasury as PalletInfoAccess>::index()`
      with `rococo_runtime_constants::TREASURY_PALLET_ID`.
      - Added `check_treasury_pallet_id` to the relay runtimes to ensure that
      the constant is aligned with the pallet id.
      - Added "Rococo Treasury" to the waived locations (that will not be
      charged fees in the executor) for `BridgeHubRococo` (to be aligned with
      AssetHubs).

      Introduce XcmFeesToAccount fee manager (#1234) · 3dece311
      Keith Yeung authored
      
      
      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`).

      cumulus: add asset-hub-rococo runtime based on asset-hub-kusama and add asset-bridging support to it (#1215)
      
      This commit adds Rococo Asset Hub dedicated runtime so we can test new
      features here, before merging them in Kusama Asset Hub.
      Also adds one such feature: asset transfer over bridge (Rococo AssetHub
      <> Wococo AssetHub)
      
      - clone `asset-hub-kusama-runtime` -> `asset-hub-rococo-runtime`
      - make it use Rococo primitives, names, assets, constants, etc
      - add asset-transfer-over-bridge support to Rococo AssetHub <> Wococo
      AssetHub
      
      Fixes #1128
