      Make `IdentityInfo` generic in `pallet-identity` (#1661) · 91851951
      georgepisaltu authored
      Fixes #179 
      
      # Description
      
      This PR makes the structure containing identity information used in
      `pallet-identity` generic through the pallet `Config`. Additionally, the
      old structure is now available in a separate module called `simple`
      (pending rename) and is compatible with the new interface.
      
      Another change in this PR is that while the `additional` field in
      `IdentityInfo` stays for backwards compatibility reasons, the associated
      costs are stil present in the pallet through the `additional` function
      in the `IdentityInformationProvider` interface. This function is marked
      as deprecated as it is only a temporary solution to the backwards
      compatibility problem we had. In short, we could have removed the
      additional fields in the struct and done a migration, but we chose to
      wait and do it off-chain through the genesis of the system parachain.
      After we move the identity pallet to the parachain, additional fields
      will be migrated into the existing fields and the `additional` key-value
      store will be removed. Until that happens, this interface will provide
      the necessary information to properly account for the associated costs.
      
      Additionally, this PR fixes an unrelated issue; the `IdentityField` enum
      used to represent the fields as bitflags couldn't store more than 8
      fields, even though it was marked as `#[repr(u64)]`. This was because of
      the `derive` implementation of `TypeInfo`, which assumed `u8` semantics.
      The custom implementation of this trait in

      fixes the issue.

      Ensure correct variant count in `Runtime[Hold/Freeze]Reason` (#1900) · 35eb133b

      ## 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.

      `xcm`: Change `TypeInfo::path` to not include `staging` (#1948) · f3bf5c1a
      Bastian Köcher authored
      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

      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`).

      Treasury spends various asset kinds (#1333) · cb944dc5
      Muharem Ismailov authored
      
      
      ### 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.

      [NPoS] Fix for Reward Deficit in the pool (#1255) · f820dc0a
      Ankan authored
      closes https://github.com/paritytech/polkadot-sdk/issues/158.
      partially addresses
      https://github.com/paritytech/polkadot-sdk/issues/226.
      
      Instead of fragile calculation of current balance by looking at `free
      balance - ED`, Nomination Pool now freezes ED in the pool reward account
      to restrict an account from going below minimum balance. This also has a
      nice side effect that if ED changes, we know how much is the imbalance
      in ED frozen in the pool and the current required ED. A pool operator
      can diligently top up the pool with the deficit in ED or vice versa,
      withdraw the excess they transferred to the pool.
      
      ## Notable changes
      - New call `adjust_pool_deposit`: Allows to top up the deficit or
      withdraw the excess deposited funds to the pool.
      - Uses Fungible trait (instead of Currency trait). Since NP was not
      doing any locking/reserving previously, no migration is needed for this.
      - One time migration of freezing ED from each of the existing pools (not
      very PoV friendly but fine for relay chain).

      Remove kusama and polkadot runtime crates (#1731) · bf90cb0b
      Bastian Köcher authored
      This pull request is removing the Kusama and Polkadot runtime crates. As
      still some crates dependent on the runtime crates, this pull request is
      doing some more changes.
      
      - It removes the `hostperfcheck` CLI command. This CLI command could
      compare the current node against the standard hardware by doing some
      checks. Later we added the hardware benchmark feature to Substrate. This
      hardware benchmark is running on every node startup and prints a warning
      if the current node is too slow. This makes this CLI command a duplicate
      that was also depending on the kusama runtime.
      
      - The pull request is removing the emulated integration tests that were
      requiring the Kusama or Polkadot runtime crates.

      Disable Calls to Identity Pallet (#1476) · 771c3fbd
      joe petrowski authored
      This PR filters calls from the Identity pallet from all Relay Chain
      runtimes as preparation to move the identity state and logic to a system
      parachain within each network.
      
      After this change is deployed to a runtime, no more changes such as
      adding new sub-identities will be possible. The frozen state will be
      part of the genesis state of the system chain. After the system chain
      launches, the pallet and all state will be removed from each Relay
      Chain.
      
      Applications and UIs that render display information from this pallet
      will need to read from the system chain when it launches.

      Stabilize `VersionedMigration` (#1503) · 72de70c7
      Liam Aharon authored
      `VersionedMigration` has become somewhat widely used for handling
      version bumps in migrations the last few months.
      
      It is currently behind the `experimental` feature flag, requiring every
      pallet that writes a new migration with version bumps to set up the
      `experimental` flag in their own Cargo.tomls, and also for every runtime
      using these pallets to explicitly enable the `experimental` flag for
      each pallet.
      
      This is becoming quite verbose, and I can only see the number of pallets
      requiring the experimental flag increasing for no other reason than
      using what has become a commonly used feature.
      
      Additionally, I'm writing migration docs and would like to avoid
      stepping through how to use the `experimental` feature to get
      `VersionedMigration` working.
      
      Since the feature has been used in production for some time now without
      any reported issues, is becoming commonly used and ready to advertise in
      docs, I feel this is a good time to make it non-experimental.
