      Set clippy lints in workspace (requires rust 1.74) (#2390) · be8e6268
      Squirrel authored
      
      
      We currently use a bit of a hack in `.cargo/config` to make sure that
      clippy isn't too annoying by specifying the list of lints.
      
      There is now a stable way to define lints for a workspace. The only down
      side is that every crate seems to have to opt into this so there's a
      *few* files modified in this PR.
      
      Dependencies:
      
      - [x] PR that upgrades CI to use rust 1.74 is merged.

      Tests for BridgeHub(s) <> remote GRANDPA chain (#2692) · 9ecb2d33
      Svyatoslav Nikolsky authored
      So far the `bridge-hub-test-utils` contained a tests set for testing
      BridgeHub runtime that is bridging with the remote **parachain**. But we
      have https://github.com/paritytech/polkadot-sdk/pull/2540 coming, which
      would add Rococo <> Bulletin chain bridge (where Bulletin = standalone
      chain that is using GRANDPA finality). Then it'll be expanded to
      Polkadot BH as well.
      
      So this PR adds the same set of tests to the `bridge-hub-test-utils`,
      but for the case when remote chain is the chain with GRANDPA finality.
      There's a lot of changes in this PR - I'll describe some:
      - I've added `BasicParachainRuntime` trait to decrease number of lines
      we need to add to `where` clause. Could revert, but imo it is useful;
      - `cumulus/parachains/runtimes/bridge-hubs/test-utils/src/test_data` is
      a submodule for generating test data for the test sets.
      `from_parachain.rs` is used in tests for the case when remote chain is a
      parachain, `from_grandpa_chain.rs` - for the bridges with remote GRANDPA
      chains. `mod.rs` has some code, shared by both types of tests;
      - `cumulus/parachains/runtimes/bridge-hubs/test-utils/src/test_data` is
      a submodule with all test cases. The `mod.rs` has tests, suitable for
      all cases. There's also `wth_parachain.rs` and `with_grandpa_chain.rs`
      with the same meaning as above;
      - I've merged the "core" code of two previous tests -
      `relayed_incoming_message_works` and `complex_relay_extrinsic_works`
      into one single `relayed_incoming_message_works` test. So now we are
      always constructing extrinsics and are dispatching them using executive
      module (meaning all signed extensions are also tested).
      
      New test set is used here:
      https://github.com/paritytech/polkadot-sdk/pull/2540. Once this PR is
      merged, I'll merge that other PR with master to remove duplicate
      changes.
      
      I'm also planning to cleanup generic constraints + remove some
      unnecessary assumptions about used chains in a follow-up PRs. But for
      now I think this PR has enough changes, so don't want to complicate it
      even more.
      
      ---
      
      Breaking changes for the code that have used those tests before:
      - the `construct_and_apply_extrinsic` callback now accepts the
      `RuntimeCall` instead of the `pallet_utility::Call`;
      - the `construct_and_apply_extrinsic` now may be called multiple times
      for the single test, so make sure the `frame_system::CheckNonce` is
      correctly constructed;
      - all previous tests have been moved from
      `bridge_hub_test_utils::test_cases` to
      `bridge_hub_test_utils::test_cases::from_parachain` module;
      - there are several changes in test arguments - please refer to
      https://github.com/paritytech/polkadot-sdk/compare/sv-tests-for-bridge-with-remote-grandpa-chain?expand=1#diff-79a28d4d3e1749050341c2424f00c4c139825b1a20937767f83e58b95166735c

      Ensure xcm versions over bridge (on sending chains) (#2481) · 575b8f8d
      Branislav Kontur authored
      ## 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/63ac2471/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/2183669d/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

      Changelogs local generation (#1411) · 42a3afba
      Chevdor authored
      
      
      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
      ```

      Muharem Ismailov authored
      
      
      Treasury Pallet Instance for the Fellowship in Westend Collectives.
      
      In this update, we present a Treasury Pallet Instance that is under the
      control of the Fellowship body, with oversight from the Root and
      Treasurer origins. Here's how it is governed:
      - the Root origin have the authority to reject or approve spend
      proposals, with no amount limit for approvals.
      - the Treasurer origin have the authority to reject or approve spend
      proposals, with approval limits of up to 10,000,000 DOT.
      - Voice of all Fellows ranked at 3 or above can reject or approve spend
      proposals, with a maximum approval limit of 10,000 DOT.
      - Voice of Fellows ranked at 4 or above can also reject or approve spend
      proposals, with a maximum approval limit of 10,000,000 DOT.
      
      Additionally, we introduce the Asset Rate Pallet Instance to establish
      conversion rates from asset A to B. This is used to determine if a
      proposed spend amount involving a non-native asset is permissible by the
      commanding origin. The rates can be set up by the Root, Treasurer
      origins, or Voice of all Fellows.

      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.

      pallet-xcm: add new flexible `transfer_assets()` call/extrinsic (#2388) · e7651cf4
      Adrian Catangiu authored
      # 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.

      Contracts: use compiled rust tests (#2347) · 2135fa87
      PG Herveou authored
      
      
      see #2189
      
      This PR does the following:
      - Bring the user api functions into a new pallet-contracts-uapi (They
      are currently defined in ink!
      [here])(https://github.com/paritytech/ink/blob/master/crates/env/src/engine/on_chain/ext.rs)
      - Add older api versions and unstable to the user api trait.
      - Remove pallet-contracts-primitives and bring the types it defined in
      uapi / pallet-contracts
      - Add the infrastructure to build fixtures from Rust files and test it
      works by replacing `dummy.wat` and `call.wat`
      - Move all the doc from wasm/runtime.rs to pallet-contracts-uapi.
      
      This will be done in a follow up:
      - convert the rest of the test from .wat to rust
      - bring risc-v uapi up to date with wasm
      - finalize the uapi host fns, making sure everything is codegen from the
      source host fns in pallet-contracts

      New runtime `spec_version` format + backport of the bump to 1.4.0 (#2468) · 4f8048b9
      Chevdor authored
      
      
      ## 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`.

      Branislav Kontur authored
      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)

      - A mock_network and xcm_test files to test the newly added xcm-related

      Add simple collator election mechanism (#1340) · 7d735fc8
      georgepisaltu authored
      
      
      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

      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).

      Contracts: Add XCM traits to interface with contracts (#2086) · 6b7be115
      PG Herveou authored
      
      
      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>;
      }
      ```

      BridgeHub Runtimes: Change registration order of `MessageQueue` pallet (#2230) · 3f7c743d
      Vincent Geddes authored
      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/df8d5da8/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.

      `bridge-hub-westend-runtime` was added to cumulus/parachains, but wasn't
      hooked up to xcm-emulator to run tests against it.
      
      This commit addresses that ^.
