## Summary This pull request proposes a solution for improved control of the versioned XCM flow over the bridge (across different consensus chains) and resolves the situation where the sending chain/consensus has already migrated to a higher XCM version than the receiving chain/consensus. ## Problem/Motivation The current flow over the bridge involves a transfer from AssetHubRococo (AHR) to BridgeHubRococo (BHR) to BridgeHubWestend (BHW) and finally to AssetHubWestend (AHW), beginning with a reserve-backed transfer on AHR. In this process: 1. AHR sends XCM `ExportMessage` through `XcmpQueue`, incorporating XCM version checks using the `WrapVersion` feature, influenced by `pallet_xcm::SupportedVersion` (managed by `pallet_xcm::force_xcm_version` or version discovery). 2. BHR handles the `ExportMessage` instruction, utilizing the latest XCM version. The `HaulBlobExporter` converts the inner XCM to [`VersionedXcm::from`](https://github.com/paritytech/polkadot-sdk/blob/63ac2471aa0210f0ac9903bdd7d8f9351f9a635f/polkadot/xcm/xcm-builder/src/universal_exports.rs#L465-L467), also using the latest XCM version. However, challenges arise: - Incompatibility when BHW uses a different version than BHR. For instance, if BHR migrates to **XCMv4** while BHW remains on **XCMv3**, BHR's `VersionedXcm::from` uses `VersionedXcm::V4` variant, causing encoding issues for BHW. ``` /// Just a simulation of possible error, which could happen on BHW /// (this code is based on actual master without XCMv4) let encoded = hex_literal::hex!("0400"); println!("{:?}", VersionedXcm::<()>::decode(&mut &encoded[..])); Err(Error { cause: None, desc: "Could not decode `VersionedXcm`, variant doesn't exist" }) ``` - Similar compatibility issues exist between AHR and AHW. ## Solution This pull request introduces the following solutions: 1. **New trait `CheckVersion`** - added to the `xcm` module and exposing `pallet_xcm::SupportedVersion`. This enhancement allows checking the actual XCM version for desired destinations outside of the `pallet_xcm` module. 2. **Version Check in `HaulBlobExporter`** uses `CheckVersion` to check known/configured destination versions, ensuring compatibility. For example, in the scenario mentioned, BHR can store the version `3` for BHW. If BHR is on XCMv4, it will attempt to downgrade the message to version `3` instead of using the latest version `4`. 3. **Version Check in `pallet-xcm-bridge-hub-router`** - this check ensures compatibility with the real destination's XCM version, preventing the unnecessary sending of messages to the local bridge hub if versions are incompatible. These additions aim to improve the control and compatibility of XCM flows over the bridge and addressing issues related to version mismatches. ## Possible alternative solution _(More investigation is needed, and at the very least, it should extend to XCMv4/5. If this proves to be a viable option, I can open an RFC for XCM.)._ Add the `XcmVersion` attribute to the `ExportMessage` so that the sending chain can determine, based on what is stored in `pallet_xcm::SupportedVersion`, the version the destination is using. This way, we may not need to handle the version in `HaulBlobExporter`. ``` ExportMessage { network: NetworkId, destination: InteriorMultiLocation, xcm: Xcm<()> destination_xcm_version: Version, // <- new attritbute }, ``` ``` pub trait ExportXcm { fn validate( network: NetworkId, channel: u32, universal_source: &mut Option<InteriorMultiLocation>, destination: &mut Option<InteriorMultiLocation>, message: &mut Option<Xcm<()>>, destination_xcm_version: Version, , // <- new attritbute ) -> SendResult<Self::Ticket>; ``` ## Future Directions This PR does not fix version discovery over bridge, further investigation will be conducted here: https://github.com/paritytech/polkadot-sdk/issues/2417. ## TODO - [x] `pallet_xcm` mock for tests uses hard-coded XCM version `2` - change to 3 or lastest? - [x] fix `pallet-xcm-bridge-hub-router` - [x] fix HaulBlobExporter with version determination [here](https://github.com/paritytech/polkadot-sdk/blob/2183669d05f9b510f979a0cc3c7847707bacba2e/polkadot/xcm/xcm-builder/src/universal_exports.rs#L465) - [x] add unit-tests to the runtimes - [x] run benchmarks for `ExportMessage` - [x] extend local run scripts about `force_xcm_version(dest, version)` - [ ] when merged, prepare governance calls for Rococo/Westend - [ ] add PRDoc Part of: https://github.com/paritytech/parity-bridges-common/issues/2719 --------- Co-authored-by: command-bot <>

This PR introduces a script and some templates to use the prdoc involved in a release and build: - the changelog - a simple draft of audience documentation Since the prdoc presence was enforced in the middle of the version 1.5.0, not all PRs did come with a `prdoc` file. This PR creates all the missing `prdoc` files with some minimum content allowing to properly generate the changelog. The generated content is **not** suitable for the audience documentation. The audience documentation will be possible with the next version, when all PR come with a proper `prdoc`. ## Assumptions - the prdoc files for release `vX.Y.Z` have been moved under `prdoc/X.Y.Z` - the changelog requires for now for the prdoc files to contain author + topic. Thos fields are optional. The build script can be called as: ``` VERSION=X.Y.Z ./scripts/release/build-changelogs.sh ``` Related: - #1408 --------- Co-authored-by:

As suggested in this thread: https://github.com/polkadot-fellows/runtimes/pull/87#discussion_r1400237122 We already have the `IsChildSystemParachain`, which may be used at relay chain, but it can't be used at a parachain level. So let's use `AllSiblingSystemParachains` for that. I was thinking about `AllSystemParachains`, but it may cause wrong impression that it can be used at a relay chain level. --------- Co-authored-by:

# Motivation (+testing) ### Enable easy `ForeignAssets` transfers using `pallet-xcm` We had just previously added capabilities to teleport fees during reserve-based transfers, but what about reserve-transferring fees when needing to teleport some non-fee asset? This PR aligns everything under either explicit reserve-transfer, explicit teleport, or this new flexible `transfer_assets()` which can mix and match as needed with fewer artificial constraints imposed to the user. This will enable, for example, a (non-system) parachain to teleport their `ForeignAssets` assets to AssetHub while using DOT to pay fees. (the assets are teleported - as foreign assets should from their owner chain - while DOT used for fees can only be reserve-based transferred between said parachain and AssetHub). Added `xcm-emulator` tests for this scenario ^. # Description Reverts `(limited_)reserve_transfer_assets` to only allow reserve-based transfers for all `assets` including fees. Similarly `(limited_)teleport_assets` only allows teleports for all `assets` including fees. For complex combinations of asset transfers where assets and fees may have different reserves or different reserve/teleport trust configurations, users can use the newly added `transfer_assets()` extrinsic which is more flexible in allowing more complex scenarios. `assets` (excluding `fees`) must have same reserve location or otherwise be teleportable to `dest`. No limitations imposed on `fees`. - for local reserve: transfer assets to sovereign account of destination chain and forward a notification XCM to `dest` to mint and deposit reserve-based assets to `beneficiary`. - for destination reserve: burn local assets and forward a notification to `dest` chain to withdraw the reserve assets from this chain's sovereign account and deposit them to `beneficiary`. - for remote reserve: burn local assets, forward XCM to reserve chain to move reserves from this chain's SA to `dest` chain's SA, and forward another XCM to `dest` to mint and deposit reserve-based assets to `beneficiary`. - for teleports: burn local assets and forward XCM to `dest` chain to mint/teleport assets and deposit them to `beneficiary`. ## Review notes Only around 500 lines are prod code (see `pallet_xcm/src/lib.rs`), the rest of the PR is new tests and improving existing tests. --------- Co-authored-by: command-bot <>

Using taplo, fixes all our broken and inconsistent toml formatting and adds CI to keep them tidy. If people want we can customise the format rules as described here https://taplo.tamasfe.dev/configuration/formatter-options.html @ggwpez , I suggest zepter is used only for checking features are propagated, and leave formatting for taplo to avoid duplicate work and conflicts.

## Overview This PR aligns the `spec_version` formatting to the [recent changes](https://github.com/polkadot-fellows/runtimes/pull/26/files#diff-efa4caeb17487ecb13d8f5eb7863c3241d84afa2e73fbf25909a2ca89df0f362R142 ) made for the Polkadot/Kusama runtimes. It also backports the latest version `v1.4.0` bumps as `1_004_000`. ## Details During the switch from `v0.9` to `v1.x`, the format of the `spec_version` was modified from: `(M)m_ppp` for a runtime considered on version `M.m.pp`. For instance `0.9.42` had a `spec_version` of `9420`. With the transition to `v1.x`, the format was changed to a bigger number (still `u32`) formatted as `MM_mm_ppp` where `1.2.3` would be stored as `01_02_003`. This PR aligns the format with that has been introduced in the fellowship repo: `MMM_mmm_ppp`. --------- Co-authored-by:

This PR fixes two things: - relax `force_default_xcm_version` for testnet system parachains (e.g. BridgeHubWestend has now 2 and there is no way to change it to 3, so we need to call `force_xcm_version(3)` for every parachain that it is connected to, because we send XCMv3 messages) - add `Storage` item to `PolkadotXcm` pallet definition (now we cannot see storage items for `pallet_xcm` in PJS) ## TODO - [ ] when merged open PR to `polkadot-fellows/runtimes` repo

Fixes https://github.com/paritytech/polkadot-sdk/issues/106 Port of cumulus PR https://github.com/paritytech/cumulus/pull/2960 This PR adds the ability to bid for collator slots even after the max number of collators have already registered. This eliminates the first 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 # Checklist - [ ] My PR includes a detailed description as outlined in the "Description" section above - [ ] My PR follows the [labeling requirements](https://github.com/paritytech/polkadot-sdk/blob/master/docs/CONTRIBUTING.md#process ) of this project (at minimum one label for `T` required) - [ ] I have made corresponding changes to the documentation (if applicable) - [ ] I have added tests that prove my fix is effective or that my feature works (if applicable) - [ ] If this PR alters any external APIs or interfaces used by Polkadot, the corresponding Polkadot PR is ready as well as the corresponding Cumulus PR (optional) --------- Signed-off-by:

## 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).

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 https://github.com/paritytech/polkadot-sdk/pull/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>; } ``` --------- Co-authored-by:

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 https://github.com/paritytech/polkadot-sdk/pull/1246. As otherwise, changing the order of pallet registration is an ABI-breaking change.

Right now governance could only control byte-fee component of Rococo <> Westend message fees (paid at Asset Hubs). This PR changes it a bit: 1) governance now allowed to control both fee components - byte fee and base fee; 2) base fee now includes cost of "default" delivery and confirmation transactions, in addition to `ExportMessage` instruction cost.

(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. ![Untitled (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 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 --------- Signed-off-by:
