      Lifting some more dependencies to the workspace. Just using the
      most-often updated ones for now.
      It can be reproduced locally.
      
      ```sh
      # First you can check if there would be semver incompatible bumps (looks good in this case):
      $ zepter transpose dependency lift-to-workspace --ignore-errors syn quote thiserror "regex:^serde.*"
      
      # Then apply the changes:
      $ zepter transpose dependency lift-to-workspace --version-resolver=highest syn quote thiserror "regex:^serde.*" --fix
      
      # And format the changes:
      $ taplo format --config .config/taplo.toml
      ```

      [FRAME] Parameters pallet (#2061) · e53ebd8c
      Oliver Tale-Yazdi authored
      Closes #169  
      
      Fork of the `orml-parameters-pallet` as introduced by
      https://github.com/open-web3-stack/open-runtime-module-library/pull/927
      
      
      (cc @xlc)
      It greatly changes how the macros work, but keeps the pallet the same.
      The downside of my code is now that it does only support constant keys
      in the form of types, not value-bearing keys.
      I think this is an acceptable trade off, give that it can be used by
      *any* pallet without any changes.
      
      The pallet allows to dynamically set parameters that can be used in
      pallet configs while also restricting the updating on a per-key basis.
      The rust-docs contains a complete example.
      
      Changes:
      - Add `parameters-pallet`
      - Use in the kitchensink as demonstration
      - Add experimental attribute to define dynamic params in the runtime.
      - Adding a bunch of traits to `frame_support::traits::dynamic_params`
      that can be re-used by the ORML macros
      
      ## Example
      
      First to define the parameters in the runtime file. The syntax is very
      explicit about the codec index and errors if there is no.
      ```rust
      #[dynamic_params(RuntimeParameters, pallet_parameters::Parameters::<Runtime>))]
      pub mod dynamic_params {
      	use super::*;
      
      	#[dynamic_pallet_params]
      	#[codec(index = 0)]
      	pub mod storage {
      		/// Configures the base deposit of storing some data.
      		#[codec(index = 0)]
      		pub static BaseDeposit: Balance = 1 * DOLLARS;
      
      		/// Configures the per-byte deposit of storing some data.
      		#[codec(index = 1)]
      		pub static ByteDeposit: Balance = 1 * CENTS;
      	}
      
      	#[dynamic_pallet_params]
      	#[codec(index = 1)]
      	pub mod contracts {
      		#[codec(index = 0)]
      		pub static DepositPerItem: Balance = deposit(1, 0);
      
      		#[codec(index = 1)]
      		pub static DepositPerByte: Balance = deposit(0, 1);
      	}
      }
      ```
      
      Then the pallet is configured with the aggregate:  
      ```rust
      impl pallet_parameters::Config for Runtime {
      	type AggregratedKeyValue = RuntimeParameters;
      	type AdminOrigin = EnsureRootWithSuccess<AccountId, ConstBool<true>>;
      	...
      }
      ```
      
      And then the parameters can be used in a pallet config:
      ```rust
      impl pallet_preimage::Config for Runtime {
      	type DepositBase = dynamic_params::storage::DepositBase;
      }
      ```
      
      A custom origin an be defined like this:  
      ```rust
      pub struct DynamicParametersManagerOrigin;
      
      impl EnsureOriginWithArg<RuntimeOrigin, RuntimeParametersKey> for DynamicParametersManagerOrigin {
      	type Success = ();
      
      	fn try_origin(
      		origin: RuntimeOrigin,
      		key: &RuntimeParametersKey,
      	) -> Result<Self::Success, RuntimeOrigin> {
      		match key {
      			RuntimeParametersKey::Storage(_) => {
      				frame_system::ensure_root(origin.clone()).map_err(|_| origin)?;
      				return Ok(())
      			},
      			RuntimeParametersKey::Contract(_) => {
      				frame_system::ensure_root(origin.clone()).map_err(|_| origin)?;
      				return Ok(())
      			},
      		}
      	}
      
      	#[cfg(feature = "runtime-benchmarks")]
      	fn try_successful_origin(_key: &RuntimeParametersKey) -> Result<RuntimeOrigin, ()> {
      		Ok(RuntimeOrigin::Root)
      	}
      }
      ```

      First in a series of PRs that reduces our use of sp-std with a view to
      deprecating it.
      
      This is just looking at /substrate and moving some of the references
      from `sp-std` to `core`.
      These particular changes should be uncontroversial.
      
      Where macros are used `::core` should be used to remove any ambiguity.

      Branislav Kontur authored
      [frame] `#[pallet::composite_enum]` improved variant count handling + removed `pallet_balances`'s `MaxHolds` config (#2657)
      
      I started this investigation/issue based on @liamaharon question
      [here](https://github.com/paritytech/polkadot-sdk/pull/1801#discussion_r1410452499).
      
      ## Problem
      
      The `pallet_balances` integrity test should correctly detect that the
      runtime has correct distinct `HoldReasons` variant count. I assume the
      same situation exists for RuntimeFreezeReason.
      
      It is not a critical problem, if we set `MaxHolds` with a sufficiently
      large value, everything should be ok. However, in this case, the
      integrity_test check becomes less useful.
      
      **Situation for "any" runtime:**
      - `HoldReason` enums from different pallets:
      ```rust
              /// from pallet_nis
              #[pallet::composite_enum]
      	pub enum HoldReason {
      		NftReceipt,
      	}
      
              /// from pallet_preimage
              #[pallet::composite_enum]
      	pub enum HoldReason {
      		Preimage,
      	}
      
              // from pallet_state-trie-migration
              #[pallet::composite_enum]
      	pub enum HoldReason {
      		SlashForContinueMigrate,
      		SlashForMigrateCustomTop,
      		SlashForMigrateCustomChild,
      	}
      ```
      
      - generated `RuntimeHoldReason` enum looks like:
      ```rust
      pub enum RuntimeHoldReason {
      
          #[codec(index = 32u8)]
          Preimage(pallet_preimage::HoldReason),
      
          #[codec(index = 38u8)]
          Nis(pallet_nis::HoldReason),
      
          #[codec(index = 42u8)]
          StateTrieMigration(pallet_state_trie_migration::HoldReason),
      }
      ```
      
      - composite enum `RuntimeHoldReason` variant count is detected as `3`
      - we set `type MaxHolds = ConstU32<3>`
      - `pallet_balances::integrity_test` is ok with `3`(at least 3)
      
      However, the real problem can occur in a live runtime where some
      functionality might stop working. This is due to a total of 5 distinct
      hold reasons (for pallets with multi-instance support, it is even more),
      and not all of them can be used because of an incorrect `MaxHolds`,
      which is deemed acceptable according to the `integrity_test`:
        ```
        // pseudo-code - if we try to call all of these:
      
      T::Currency::hold(&pallet_nis::HoldReason::NftReceipt.into(),
      &nft_owner, deposit)?;
      T::Currency::hold(&pallet_preimage::HoldReason::Preimage.into(),
      &nft_owner, deposit)?;
      
      T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForContinueMigrate.into(),
      &nft_owner, deposit)?;
      
        // With `type MaxHolds = ConstU32<3>` these two will fail
      
      T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForMigrateCustomTop.into(),
      &nft_owner, deposit)?;
      
      T::Currency::hold(&pallet_state_trie_migration::HoldReason::SlashForMigrateCustomChild.into(),
      &nft_owner, deposit)?;
        ```  
      
      
      ## Solutions
      
      A macro `#[pallet::*]` expansion is extended of `VariantCount`
      implementation for the `#[pallet::composite_enum]` enum type. This
      expansion generates the `VariantCount` implementation for pallets'
      `HoldReason`, `FreezeReason`, `LockId`, and `SlashReason`. Enum variants
      must be plain enum values without fields to ensure a deterministic
      count.
      
      The composite runtime enum, `RuntimeHoldReason` and
      `RuntimeFreezeReason`, now sets `VariantCount::VARIANT_COUNT` as the sum
      of pallets' enum `VariantCount::VARIANT_COUNT`:
      ```rust
      #[frame_support::pallet(dev_mode)]
      mod module_single_instance {
      
      	#[pallet::composite_enum]
      	pub enum HoldReason {
      		ModuleSingleInstanceReason1,
      		ModuleSingleInstanceReason2,
      	}
      ...
      }
      
      #[frame_support::pallet(dev_mode)]
      mod module_multi_instance {
      
      	#[pallet::composite_enum]
      	pub enum HoldReason<I: 'static = ()> {
      		ModuleMultiInstanceReason1,
      		ModuleMultiInstanceReason2,
      		ModuleMultiInstanceReason3,
      	}
      ...
      }
      
      
      impl self::sp_api_hidden_includes_construct_runtime::hidden_include::traits::VariantCount
          for RuntimeHoldReason
      {
          const VARIANT_COUNT: u32 = 0
              + module_single_instance::HoldReason::VARIANT_COUNT
              + module_multi_instance::HoldReason::<module_multi_instance::Instance1>::VARIANT_COUNT
              + module_multi_instance::HoldReason::<module_multi_instance::Instance2>::VARIANT_COUNT
              + module_multi_instance::HoldReason::<module_multi_instance::Instance3>::VARIANT_COUNT;
      }
      ```
      
      In addition, `MaxHolds` is removed (as suggested
      [here](https://github.com/paritytech/polkadot-sdk/pull/2657#discussion_r1443324573))
      from `pallet_balances`, and its `Holds` are now bounded to
      `RuntimeHoldReason::VARIANT_COUNT`. Therefore, there is no need to let
      the runtime specify `MaxHolds`.

      rpc: backpressured RPC server (bump jsonrpsee 0.20) (#1313) · e16ef086
      Niklas Adolfsson authored
      This is a rather big change in jsonrpsee, the major things in this bump
      are:
      - Server backpressure (the subscription impls are modified to deal with
      that)
      - Allow custom error types / return types (remove jsonrpsee::core::Error
      and jsonrpee::core::CallError)
      - Bug fixes (graceful shutdown in particular not used by substrate
      anyway)
         - Less dependencies for the clients in particular
         - Return type requires Clone in method call responses
         - Moved to tokio channels
         - Async subscription API (not used in this PR)
      
      Major changes in this PR:
      - The subscriptions are now bounded and if subscription can't keep up
      with the server it is dropped
      - CLI: add parameter to configure the jsonrpc server bounded message
      buffer (default is 64)
      - Add our own subscription helper to deal with the unbounded streams in
      substrate
      
      The most important things in this PR to review is the added helpers
      functions in `substrate/client/rpc/src/utils.rs` and the rest is pretty
      much chore.
      
      Regarding the "bounded buffer limit" it may cause the server to handle
      the JSON-RPC calls
      slower than before.
      
      The message size limit is bounded by "--rpc-response-size" thus "by
      default 10MB * 64 = 640MB"
      but the subscription message size is not covered by this limit and could
      be capped as well.
      
      Hopefully the last release prior to 1.0, sorry in advance for a big PR

      - 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

      ## Fixes
      
      ### `Unbalanced::decrease_balance` can reap account when called with
      `Preservation::Preserve`
      There is a potential issue in the default implementation of
      `Unbalanced::decrease_balance`. The implementation can delete an account
      even when it is called with `preservation: Preservation::Preserve`. This
      seems to contradict the documentation of `Preservation::Preserve`:
      
      ```rust
      	/// The account may not be killed and our provider reference must remain (in the context of
      	/// tokens, this means that the account may not be dusted).
      	Preserve,
      ```
      
      I updated `Unbalanced::decrease_balance` to return
      `Err(TokenError::BelowMinimum)` when a withdrawal would cause the
      account to be reaped and `preservation: Preservation::Preserve`.
      
      - [ ] TODO Confirm with @gavofyork that this is correct behavior
      
      Test for this behavior:
      
      
      https://github.com/paritytech/polkadot-sdk/blob/e5c876dd6b59e2b7dbacaa4538cb42c802db3730/substrate/frame/support/src/traits/tokens/fungible/conformance_tests/regular.rs#L912-L937
      
      ### `Balanced::pair` returning non-canceling pairs
      
      `Balanced::pair` is supposed to create a pair of imbalances that cancel
      each other out. However this is not the case when the method is called
      with an amount greater than the total supply.
      
      In the existing default implementation, `Balanced::pair` creates a pair
      by first rescinding the balance, creating `Debt`, and then issuing the
      balance, creating `Credit`.
      
      When creating `Debt`, if the amount to create exceeds the
      `total_supply`, `total_supply` units of `Debt` are created *instead* of
      `amount` units of `Debt`. This can lead to non-canceling amount of
      `Credit` and `Debt` being created.
      
      To address this, I create the credit and debt directly in the method
      instead of calling `issue` and `rescind`.
      
      Test for this behavior:
      
      
      https://github.com/paritytech/polkadot-sdk/blob/e5c876dd6b59e2b7dbacaa4538cb42c802db3730/substrate/frame/support/src/traits/tokens/fungible/conformance_tests/regular.rs#L1323-L1346
      
      ### `Balances` pallet `active_issuance` 'underflow'
      
      This PR resolves an issue in the `Balances` pallet that can lead to odd
      behavior of `active_issuance`.
      
      Currently, the Balances pallet doesn't check if `InactiveIssuance`
      remains less than or equal to `TotalIssuance` when supply is
      deactivated. This allows `InactiveIssuance` to be greater than
      `TotalIssuance`, which can result in unexpected behavior from the
      perspective of the fungible API.
      
      `active_issuance` is derived from
      `TotalIssuance.saturating_sub(InactiveIssuance)`.
      
      If an `amount` is deactivated that causes `InactiveIssuance` to become
      greater TotalIssuance, `active_issuance` will return 0. However once in
      that state, reactivating an amount will not increase `active_issuance`
      by the reactivated `amount` as expected.
      
      Consider this test where the last assertion would fail due to this
      issue:
      
      
      https://github.com/paritytech/polkadot-sdk/blob/e5c876dd6b59e2b7dbacaa4538cb42c802db3730/substrate/frame/support/src/traits/tokens/fungible/conformance_tests/regular.rs#L1036-L1071
      
      
      
      To address this, I've modified the `deactivate` function to ensure
      `InactiveIssuance` never surpasses `TotalIssuance`.

      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.
