      Fix clippy lints behind feature gates and add new CI step all features (#2569) · d68868f6
      Dónal Murray authored
      
      
      Many clippy lints usually enforced by `-Dcomplexity` and `-Dcorrectness`
      are not caught by CI as they are gated by `features`, like
      `runtime-benchmarks`, while the clippy CI job runs with only the default
      features for all targets.
      
      This PR also adds a CI step to run clippy with `--all-features` to
      ensure the code quality is maintained behind feature gates from now on.
      
      To improve local development, clippy lints are downgraded to warnings,
      but they still will result in an error at CI due to the `-Dwarnings`
      rustflag.

      Add Authorize Upgrade Pattern to Frame System (#2682) · 280aa0b5
      joe petrowski authored
      Adds the `authorize_upgrade` -> `enact_authorized_upgrade` pattern to
      `frame-system`. This will be useful for upgrading bridged chains that
      are under the governance of Polkadot without passing entire runtime Wasm
      blobs over a bridge.
      
      Notes:
      
      - Changed `enact_authorized_upgrade` to `apply_authorized_upgrade`.
      Personal opinion, "apply" more accurately expresses what it's doing. Can
      change back if outvoted.
      - Remove `check_version` in favor of two extrinsics, so as to make
      _checked_ the default.
      - Left calls in `parachain-system` and marked as deprecated to prevent
      breaking the API. They just call into the `frame-system` functions.
      - Updated `frame-system` benchmarks to v2 syntax.

      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.

      *few* files modified in this PR.

      Approve multiple candidates with a single signature (#1191) · a84dd0db
      Alexandru Gheorghe authored
      Initial implementation for the plan discussed here: https://github.com/paritytech/polkadot-sdk/issues/701
      Built on top of https://github.com/paritytech/polkadot-sdk/pull/1178
      v0: https://github.com/paritytech/polkadot/pull/7554,
      
      ## Overall idea
      
      When approval-voting checks a candidate and is ready to advertise the
      approval, defer it in a per-relay chain block until we either have
      MAX_APPROVAL_COALESCE_COUNT candidates to sign or a candidate has stayed
      MAX_APPROVALS_COALESCE_TICKS in the queue, in both cases we sign what
      candidates we have available.
      
      This should allow us to reduce the number of approvals messages we have
      to create/send/verify. The parameters are configurable, so we should
      find some values that balance:
      
      - Security of the network: Delaying broadcasting of an approval
      shouldn't but the finality at risk and to make sure that never happens
      we won't delay sending a vote if we are past 2/3 from the no-show time.
      - Scalability of the network: MAX_APPROVAL_COALESCE_COUNT = 1 &
      MAX_APPROVALS_COALESCE_TICKS =0, is what we have now and we know from
      the measurements we did on versi, it bottlenecks
      approval-distribution/approval-voting when increase significantly the
      number of validators and parachains
      - Block storage: In case of disputes we have to import this votes on
      chain and that increase the necessary storage with
      MAX_APPROVAL_COALESCE_COUNT * CandidateHash per vote. Given that
      disputes are not the normal way of the network functioning and we will
      limit MAX_APPROVAL_COALESCE_COUNT in the single digits numbers, this
      should be good enough. Alternatively, we could try to create a better
      way to store this on-chain through indirection, if that's needed.
      
      ## Other fixes:
      - Fixed the fact that we were sending random assignments to
      non-validators, that was wrong because those won't do anything with it
      and they won't gossip it either because they do not have a grid topology
      set, so we would waste the random assignments.
      - Added metrics to be able to debug potential no-shows and
      mis-processing of approvals/assignments.
      
      ## TODO:
      - [x] Get feedback, that this is moving in the right direction. @ordian
      @sandreim @eskimor @burdges, let me know what you think.
      - [x] More and more testing.
      - [x]  Test in versi.
      - [x] Make MAX_APPROVAL_COALESCE_COUNT &
      MAX_APPROVAL_COALESCE_WAIT_MILLIS a parachain host configuration.
      - [x] Make sure the backwards compatibility works correctly
      - [x] Make sure this direction is compatible with other streams of work:
      https://github.com/paritytech/polkadot-sdk/issues/635 &

      - [x] Final versi burn-in before merging

      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

      Staking: Add `deprecate_controller_batch` AdminOrigin call (#2589) · 048a9c27
      Ross Bulat authored
      
      
      Partially Addresses #2500
      
      Adds a `deprecate_controller_batch` call to the staking pallet that is
      callable by `Root` and `StakingAdmin`. To be used for controller account
      deprecation and removed thereafter. Adds
      `MaxControllersDeprecationBatch` pallet constant that defines max
      possible deprecations per call.
      
      - [x] Add `deprecate_controller_batch` call, and
      `MaxControllersInDeprecationBatch` constant.
      - [x] Add tests, benchmark, weights. Tests that weight is only consumed
      if unique pair.
      - [x] Adds `StakingAdmin` origin to staking's `AdminOrigin` type in
      westend runtime.
      - [x] Determined that worst case 5,900 deprecations does fit into
      `maxBlock` `proofSize` and `refTime` in both normal and operational
      thresholds, meaning we can deprecate all controllers for each network in
      one call.
      
      ## Block Weights
      
      By querying `consts.system.blockWeights` we can see that the
      `deprecate_controller_batch` weights fit within the `normal` threshold
      on Polkadot.
      
      #### `controller_deprecation_batch` where i = 5900:
      #### Ref time: 69,933,325,300
      #### Proof size: 21,040,390

      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.

      `AllSiblingSystemParachains` for that. I was thinking about

      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.

      Pools: Add ability to configure commission claiming permissions (#2474) · 75062717
      Ross Bulat authored
      Addresses #409.
      
      This request has been raised by multiple community members - the ability
      for the nomination pool root role to configure permissionless commission
      claiming:
      
      > Would it be possible to have a claim_commission_other extrinsic for
      claiming commission of nomination pools permissionless?
      
      This PR does not quite introduce this additional call, but amends
      `do_claim_commission` to check a new `claim_permission` field in the
      `Commission` struct, configured by an enum:
      
      ```
      enum CommissionClaimPermission {
         Permissionless,
         Account(AccountId),
      }
      ```
      This can be optionally set in a bonded pool's
      `commission.claim_permission` field:
      
      ```
      struct BondedPool {
         commission: {
            <snip>
            claim_permission: Option<CommissionClaimPermission<T::AccountId>>,
         },
         <snip>
      }
      ```
      
      This is a new field and requires a migration to add it to existing
      pools. This will be `None` on pool creation, falling back to the `root`
      role having sole access to claim commission if it is not set; this is
      the behaviour as it is today. Once set, the field _can_ be set to `None`
      again.
      
      #### Changes
      - [x] Add `commision.claim_permission` field.
      - [x] Add `can_claim_commission` and amend `do_claim_commission`.
      - [x] Add `set_commission_claim_permission` call.
      - [x] Test to cover new configs and call.
      - [x] Add and amend benchmarks.
      - [x] Generate new weights + slot into call
      `set_commission_claim_permission`.
      - [x] Add migration to introduce `commission.claim_permission`, bump
      storage version.
      - [x] Update Westend weights.
      - [x] Migration working.

      Identity Deposits Relay to Parachain Migration (#1814) · c79b234b
      joe petrowski authored
      The goal of this PR is to migrate Identity deposits from the Relay Chain
      to a system parachain.
      
      The problem I want to solve is that `IdentityOf` and `SubsOf` both store
      an amount that's held in reserve as a storage deposit. When migrating to
      a parachain, we can take a snapshot of the actual `IdentityInfo` and
      sub-account mappings, but should migrate (off chain) the `deposit`s to
      zero, since the chain (and by extension, accounts) won't have any funds
      at genesis.
      
      The good news is that we expect parachain deposits to be significantly
      lower (possibly 100x) on the parachain. That is, a deposit of 21 DOT on
      the Relay Chain would need 0.21 DOT on a parachain. This PR proposes to
      migrate the deposits in the following way:
      
      1. Introduces a new pallet with two extrinsics: 
      - `reap_identity`: Has a configurable `ReapOrigin`, which would be set
      to `EnsureSigned` on the Relay Chain (i.e. callable by anyone) and
      `EnsureRoot` on the parachain (we don't want identities reaped from
      there).
      - `poke_deposit`: Checks what deposit the pallet holds (at genesis,
      zero) and attempts to update the amount based on the calculated deposit
      for storage data.
      2. `reap_identity` clears all storage data for a `target` account and
      unreserves their deposit.
      3. A `ReapIdentityHandler` teleports the necessary DOT to the parachain
      and calls `poke_deposit`. Since the parachain deposit is much lower, and
      was just unreserved, we know we have enough.
      
      One awkwardness I ran into was that the XCMv3 instruction set does not
      provide a way for the system to teleport assets without a fee being
      deducted on reception. Users shouldn't have to pay a fee for the system
      to migrate their info to a more efficient location. So I wrote my own
      program and did the `InitiateTeleport` accounting on my own to send a
      program with `UnpaidExecution`. Have discussed an
      `InitiateUnpaidTeleport` instruction with @franciscoaguirre . Obviously
      any chain executing this would have to pass a `Barrier` for free
      execution.
      
      TODO:
      
      - [x] Confirm People Chain ParaId
      - [x] Confirm People Chain deposit rates (determined in
      https://github.com/paritytech/polkadot-sdk/pull/2281

      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).

      Remove the `GRANDPA_AUTHORITIES_KEY` key and its usage. Apparently this
      was used in the early days to communicate the grandpa authorities to the
      node. However, we have now a runtime api that does this for us. So, this
      pull request is moving from the custom managed storage item to a FRAME
      managed storage item.
      
      This pr also includes a migration for doing the switch on a running
      chain.

      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>;
      }
      ```
