      pallet-asset-conversion: Decoupling Native Currency Dependancy (#2031) · 4f832ea8
      Muharem Ismailov authored

      Decoupling Pallet from the Concept of Native Currency
      
      Currently, the pallet is intrinsically linked with the concept of native
      currency, requiring users to provide implementations of the
      `fungible::*` and `fungibles::*` traits to interact with native and non
      native assets. This incapsulates some non-related to the pallet
      complexity and makes it less adaptable in contexts where the native
      currency concept is absent.
      
      With this PR, the dependence on `fungible::*` for liquidity-supplying
      assets has been removed. Instead, the native and non-native currencies'
      handling is now overseen by a single type that implements the
      `fungibles::*` traits. To simplify this integration, types have been
      introduced to facilitate the creation of a union between `fungible::*`
      and `fungibles::*` implementations, producing a unified `fungibles::*`
      type.
      
      One of the reasons driving these changes is the ambition to create a
      more user-friendly API for the `SwapCredit` implementation. Given that
      it interacts with two distinct credit types from `fungible` and
      `fungibles`, a unified type was introduced. Clients now manage potential
      conversion failures for those credit types. In certain contexts, it's
      vital to guarantee that operations are fail-safe, like in this impl -
      [PR](https://github.com/paritytech/polkadot-sdk/pull/1845), place in
      [code](https://github.com/paritytech/polkadot-sdk/blob/20b85a5f
      
      /cumulus/primitives/utility/src/lib.rs#L429).
      
      Additional Updates:
      - abstracted the pool ID and its account derivation logic via trait
      bounds, along with common implementation offerings;
      - removed `inc_providers` on a pool creation for the pool account;
      - benchmarks:
      -- swap complexity is N, not const;
      -- removed `From<u128> + Into<u128>` bound from `T::Balance`;
      -- removed swap/liquidity/.. amount constants, resolve them dynamically
      based on pallet configuration;
      -- migrated to v2 API;
      - `OnUnbalanced` handler for the pool creation fee, replacing direct
      transfers to a specified account ID;
      - renamed `MultiAssetId` to `AssetKind` aligning with naming across
      frame crates;

      pallet-asset-conversion: Swap Credit (#1677) · 5ce04514
      Muharem Ismailov authored
      
      
      Introduces a swap implementation that allows the exchange of a credit
      (aka Negative Imbalance) of one asset for a credit of another asset.
      
      This is particularly useful when a credit swap is required but may not
      have sufficient value to meet the ED constraint, hence cannot be
      deposited to temp account before. An example use case is when XCM fees
      are paid using an asset held in the XCM executor registry and has to be
      swapped for native currency.
      
      Additional Updates:
      - encapsulates the existing `Swap` trait impl within a transactional
      context, since partial storage mutation is possible when an error
      occurs;
      - supplied `Currency` and `Assets` impls must be implemented over the
      same `Balance` type, the `AssetBalance` generic type is dropped. This
      helps to avoid numerous type conversion and overflow cases. If those
      types are different it should be handled outside of the pallet;
      - `Box` asset kind on a pallet level, unbox on a runtime level - here
      [why](https://substrate.stackexchange.com/questions/10039/boxed-argument-of-a-dispatchable/10103#10103);
      - `path` uses `Vec` now, instead of `BoundedVec` since it is never used
      in PoV;
      - removes the `Transfer` event due to it's redundancy with the events
      emitted by `fungible/s` implementations;
      - modifies the `SwapExecuted` event type;

      [NPoS] Remove better solution threshold for unsigned submissions (#2694) · ffb2125f
      Ankan authored
      closes https://github.com/paritytech-secops/srlabs_findings/issues/78.
      
      Removes `BetterUnsignedThreshold` from pallet EPM. This will essentially
      mean any solution submitted by the validator that is strictly better
      than the current queued solution would be accepted.
      
      The reason for having these thresholds is to limit number of solutions
      submitted on-chain. However for unsigned submissions, the number of
      solutions that could be submitted on average is limited even without
      thresholding (calculation shown in the corresponding issue).

      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
      
      ### Polkadot 
      
      ```
      // consts.query.blockWeights
      
      maxBlock: {
              refTime: 2,000,000,000,000
              proofSize: 18,446,744,073,709,551,615
      }
      normal: {
       maxExtrinsic: {
      	refTime: 1,479,873,955,000
      	proofSize: 13,650,590,614,545,068,195
       }
       maxTotal: {
      	refTime: 1,500,000,000,000
      	proofSize: 13,835,058,055,282,163,711
       }
      }
      ```
      
      ### Kusama

          proofSize: 18,446,744,073,709,551,615
        }
          normal: {
            maxExtrinsic: {

      #[pallet::task]
      pub enum Task<T: Config> {

      /// Numbers to be added into the total.
      #[pallet::storage]
      pub(super) type Numbers<T: Config<I>, I: 'static = ()> =
      StorageMap<_, Twox64Concat, u32, u32, OptionQuery>;
      
      #[pallet::tasks_experimental]
      impl<T: Config<I>, I: 'static> Pallet<T, I> {
      	/// Add a pair of numbers into the totals and remove them.
      	#[pallet::task_list(Numbers::<T, I>::iter_keys())]
      	#[pallet::task_condition(|i| Numbers::<T, I>::contains_key(i))]

      			*total_values += v;
      		});

      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

      Improve `CodeExecutor` (#2358) · f2fe6a4c
      yjh authored
      
      
      Since `sp-state-machine` and `GenesisConfigBuilderRuntimeCaller` always
      set `use_native` to be false.
      We should remove this param and make `NativeElseWasmExecutor` behave
      like its name.
      It could make the above components use the correct execution strategy.
      
      Maybe polkadot do not need about `NativeElseWasmExecutor` anymore. But
      it is still needed by other chains and it's useful for debugging.

      Rework the event system of `sc-network` (#1370) · e71c484d
      Aaro Altonen authored
      
      
      This commit introduces a new concept called `NotificationService` which
      allows Polkadot protocols to communicate with the underlying
      notification protocol implementation directly, without routing events
      through `NetworkWorker`. This implies that each protocol has its own
      service which it uses to communicate with remote peers and that each
      `NotificationService` is unique with respect to the underlying
      notification protocol, meaning `NotificationService` for the transaction
      protocol can only be used to send and receive transaction-related
      notifications.
      
      The `NotificationService` concept introduces two additional benefits:
        * allow protocols to start using custom handshakes
        * allow protocols to accept/reject inbound peers
      
      Previously the validation of inbound connections was solely the
      responsibility of `ProtocolController`. This caused issues with light
      peers and `SyncingEngine` as `ProtocolController` would accept more
      peers than `SyncingEngine` could accept which caused peers to have
      differing views of their own states. `SyncingEngine` would reject excess
      peers but these rejections were not properly communicated to those peers
      causing them to assume that they were accepted.
      
      With `NotificationService`, the local handshake is not sent to remote
      peer if peer is rejected which allows it to detect that it was rejected.
      
      This commit also deprecates the use of `NetworkEventStream` for all
      notification-related events and going forward only DHT events are
      provided through `NetworkEventStream`. If protocols wish to follow each
      other's events, they must introduce additional abtractions, as is done
      for GRANDPA and transactions protocols by following the syncing protocol
      through `SyncEventStream`.

      Adds syntax for marking calls feeless (#1926) · 60c77a2e
      gupnik authored
      
      
      Fixes https://github.com/paritytech/polkadot-sdk/issues/1725
      
      This PR adds the following changes:
      1. An attribute `pallet::feeless_if` that can be optionally attached to
      a call like so:
      ```rust
      #[pallet::feeless_if(|_origin: &OriginFor<T>, something: &u32| -> bool {
      	*something == 0
      })]
      pub fn do_something(origin: OriginFor<T>, something: u32) -> DispatchResult {
           ....
      }
      ```
      The closure passed accepts references to arguments as specified in the
      call fn. It returns a boolean that denotes the conditions required for
      this call to be "feeless".
      
      2. A signed extension `SkipCheckIfFeeless<T: SignedExtension>` that
      wraps a transaction payment processor such as
      `pallet_transaction_payment::ChargeTransactionPayment`. It checks for
      all calls annotated with `pallet::feeless_if` to see if the conditions
      are met. If so, the wrapped signed extension is not called, essentially
      making the call feeless.
      
      In order to use this, you can simply replace your existing signed
      extension that manages transaction payment like so:
      ```diff
      - pallet_transaction_payment::ChargeTransactionPayment<Runtime>,
      + pallet_skip_feeless_payment::SkipCheckIfFeeless<
      +	Runtime,
      +	pallet_transaction_payment::ChargeTransactionPayment<Runtime>,
      + >,
      ```
      
      ### Todo

      `chain-spec`: getting ready for native-runtime-free world (#1256) · 8ba7a6ab
      Michal Kucharczyk authored
      
      
      This PR prepares chains specs for _native-runtime-free_  world.
      
      This PR has following changes:
      - `substrate`:
        - adds support for:
      - JSON based `GenesisConfig` to `ChainSpec` allowing interaction with
      runtime `GenesisBuilder` API.
      - interacting with arbitrary runtime wasm blob to[
      `chain-spec-builder`](https://github.com/paritytech/substrate/blob/3ef576eaeb3f42610e85daecc464961cf1295570/bin/utils/chain-spec-builder/src/lib.rs#L46)
      command line util,
      - removes
      [`code`](https://github.com/paritytech/substrate/blob/3ef576eaeb3f42610e85daecc464961cf1295570/frame/system/src/lib.rs#L660)
      from `system_pallet`
        - adds `code` to the `ChainSpec`
      - deprecates
      [`ChainSpec::from_genesis`](https://github.com/paritytech/substrate/blob/3ef576eaeb3f42610e85daecc464961cf1295570/client/chain-spec/src/chain_spec.rs#L263),
      but also changes the signature of this method extending it with `code`
      argument.
      [`ChainSpec::builder()`](https://github.com/paritytech/substrate/blob/20bee680ed098be7239cf7a6b804cd4de267983e/client/chain-spec/src/chain_spec.rs#L507)
      should be used instead.
      - `polkadot`:
      - all references to `RuntimeGenesisConfig` in `node/service` are
      removed,
      - all
      `(kusama|polkadot|versi|rococo|wococo)_(staging|dev)_genesis_config`
      functions now return the JSON patch for default runtime `GenesisConfig`,
        - `ChainSpecBuilder` is used, `ChainSpec::from_genesis` is removed,
      
      - `cumulus`:
        - `ChainSpecBuilder` is used, `ChainSpec::from_genesis` is removed,
      - _JSON_ patch configuration used instead of `RuntimeGenesisConfig
      struct` in all chain specs.

      as per [this
      discussion](https://github.com/paritytech/polkadot-sdk/pull/1661#discussion_r1371703403)
      
      > ensure through proper configuration that the new byte-based deposit is
      always lower than whatever is reserved now
      
      Not sure this is needed anymore. If the new deposits are higher than
      what is currently on chain and users don't have enough funds to reserve
      what is needed, the extrinisc fails and they're basically grandfathered
      and frozen until they add more funds and/or make a change to their
      identity. This behavior seems fine to me. Original idea
      [here](https://github.com/paritytech/polkadot-sdk/pull/1661#issuecomment-1779606319).
      
      > add an extrinsic to rejig deposits to account for the change above
      
      This was initially implemented but now removed from this PR in favor of
      the implementation detailed
      [here](https://github.com/paritytech/polkadot-sdk/pull/2088).

      `sc-block-builder`: Remove `BlockBuilderProvider` (#2099) · ca5f1056
      Bastian Köcher authored
      The `BlockBuilderProvider` was a trait that was defined in
      `sc-block-builder`. The trait was implemented for `Client`. This
      basically meant that you needed to import `sc-block-builder` any way to
      have access to the block builder. So, this trait was not providing any
      real value. This pull request is removing the said trait. Instead of the
      trait it introduces a builder for creating a `BlockBuilder`. The builder
      currently has the quite fabulous name `BlockBuilderBuilder` (I'm open to
      any better name 😅
      
      ). The rest of the pull request is about
      replacing the old trait with the new builder.
      
      # Downstream code changes
      
      If you used `new_block` or `new_block_at` before you now need to switch
      it over to the new `BlockBuilderBuilder` pattern:
      
      ```rust
      // `new` requires a type that implements `CallApiAt`. 
      let mut block_builder = BlockBuilderBuilder::new(client)
                      // Then you need to specify the hash of the parent block the block will be build on top of
      		.on_parent_block(at)
                      // The block builder also needs the block number of the parent block. 
                      // Here it is fetched from the given `client` using the `HeaderBackend`
                      // However, there also exists `with_parent_block_number` for directly passing the number
      		.fetch_parent_block_number(client)
      		.unwrap()
                      // Enable proof recording if required. This call is optional.
      		.enable_proof_recording()
                      // Pass the digests. This call is optional.
                      .with_inherent_digests(digests)
      		.build()
      		.expect("Creates new block builder");
      ```

      The check_hardware functions does not give us too much information as to

      closes https://github.com/paritytech/polkadot-sdk/issues/473.
      
      PR link in the older substrate repository:
      https://github.com/paritytech/substrate/pull/13498.
      
      # Context
      Rewards payout is processed today in a single block and limited to
      `MaxNominatorRewardedPerValidator`. This number is currently 512 on both
      Kusama and Polkadot.
      
      This PR tries to scale the nominators payout to an unlimited count in a
      multi-block fashion. Exposures are stored in pages, with each page
      capped to a certain number (`MaxExposurePageSize`). Starting out, this
      number would be the same as `MaxNominatorRewardedPerValidator`, but
      eventually, this number can be lowered through new runtime upgrades to
      limit the rewardeable nominators per dispatched call instruction.
      
      The changes in the PR are backward compatible.
      
      ## How payouts would work like after this change
      Staking exposes two calls, 1) the existing `payout_stakers` and 2)
      `payout_stakers_by_page`.
      
      ### payout_stakers
      This remains backward compatible with no signature change. If for a
      given era a validator has multiple pages, they can call `payout_stakers`
      multiple times. The pages are executed in an ascending sequence and the
      runtime takes care of preventing double claims.
      
      ### payout_stakers_by_page
      Very similar to `payout_stakers` but also accepts an extra param
      `page_index`. An account can choose to payout rewards only for an
      explicitly passed `page_index`.
      
      **Lets look at an example scenario**
      Given an active validator on Kusama had 1100 nominators,
      `MaxExposurePageSize` set to 512 for Era e. In order to pay out rewards
      to all nominators, the caller would need to call `payout_stakers` 3
      times.
      
      - `payout_stakers(origin, stash, e)` => will pay the first 512
      nominators.
      - `payout_stakers(origin, stash, e)` => will pay the second set of 512
      nominators.
      - `payout_stakers(origin, stash, e)` => will pay the last set of 76
      nominators.
      ...
      - `payout_stakers(origin, stash, e)` => calling it the 4th time would
      return an error `InvalidPage`.
      
      The above calls can also be replaced by `payout_stakers_by_page` and
      passing a `page_index` explicitly.
      
      ## Commission note
      Validator commission is paid out in chunks across all the pages where
      each commission chunk is proportional to the total stake of the current
      page. This implies higher the total stake of a page, higher will be the
      commission. If all the pages of a validator's single era are paid out,
      the sum of commission paid to the validator across all pages should be
      equal to what the commission would have been if we had a non-paged
      exposure.
      
      ### Migration Note
      Strictly speaking, we did not need to bump our storage version since
      there is no migration of storage in this PR. But it is still useful to
      mark a storage upgrade for the following reasons:
      
      - New storage items are introduced in this PR while some older storage
      items are deprecated.
      - For the next `HistoryDepth` eras, the exposure would be incrementally
      migrated to its corresponding paged storage item.
      - Runtimes using staking pallet would strictly need to wait at least
      `HistoryDepth` eras with current upgraded version (14) for the migration
      to complete. At some era `E` such that `E >
      era_at_which_V14_gets_into_effect + HistoryDepth`, we will upgrade to
      version X which will remove the deprecated storage items.
      In other words, it is a strict requirement that E<sub>x</sub> -
      E<sub>14</sub> > `HistoryDepth`, where
      E<sub>x</sub> = Era at which deprecated storages are removed from
      runtime,
      E<sub>14</sub> = Era at which runtime is upgraded to version 14.
      - For Polkadot and Kusama, there is a [tracker
      ticket](https://github.com/paritytech/polkadot-sdk/issues/433) to clean
      up the deprecated storage items.
      
      ### Storage Changes
      
      #### Added
      - ErasStakersOverview
      - ClaimedRewards
      - ErasStakersPaged
      
      #### Deprecated
      The following can be cleaned up after 84 eras which is tracked
      [here](https://github.com/paritytech/polkadot-sdk/issues/433).
      
      - ErasStakers.
      - ErasStakersClipped.
      - StakingLedger.claimed_rewards, renamed to
      StakingLedger.legacy_claimed_rewards.
      
      ### Config Changes
      - Renamed MaxNominatorRewardedPerValidator to MaxExposurePageSize.
      
      ### TODO
      - [x] Tracker ticket for cleaning up the old code after 84 eras.
      - [x] Add companion.
      - [x] Redo benchmarks before merge.
      - [x] Add Changelog for pallet_staking.

      # Description
      
      The `trigger_defensive` call has been added to the `root-testing`
      pallet. The idea is to have this pallet running on `Rococo/Westend` and
      use it to verify if the runtime monitoring works end-to-end.
      
      To accomplish this, `trigger_defensive` dispatches an event when it is
      called.
      
      Closes #1953

      Expose collection attributes from `Inspect` trait (#1914) · 0bcebac4
      Dastan authored
      # Description
      
      - What does this PR do?
      
      While working with `pallet_nfts` through `nonfungibles_v2` traits
      `Inspect, Mutate`, I found out that once you have set the collection
      attribute with `<Nfts as Mutate>::set_collection_attribute()`, it's not
      possible to read it with `<Nfts as Inspect>::collection_attribute()`
      since they use different `namespace` values. When setting the attribute,
      `AttributeNamespace::Pallet` is used, while
      `AttributeNamespace::CollectionOwner` is used when reading.
      
      more context:
      https://github.com/freeverseio/laos/issues/7#issuecomment-1766137370
      
      This PR makes `item` an optional parameter in
      `Inspect::system_attribute()`, to be able to read collection attributes.
      
      - Why are these changes needed?
      
      To be able to read collection level attributes when reading attributes
      of the collection. It will be possible to read collection attributes by
      passing `None` for `item`
      
      - How were these changes implemented and what do they affect?
      
      `NftsApi` is also affected and `NftsApi::system_attribute()` now accepts
      optional `item` parameter.
      
      ## Breaking change
      
      Because of the change in the `NftsApi::system_attribute()` method's
      `item` param, parachains who integrated the `NftsApi` need to update
      their API code and frontend integrations accordingly. AssetHubs are
      unaffected since the NftsApi wasn't released on those parachains yet.

      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
      https://github.com/paritytech/polkadot-sdk/commit/0105cc03
      
      
      fixes the issue.

      Ensure correct variant count in `Runtime[Hold/Freeze]Reason` (#1900) · 35eb133b
      Kian Paimani authored
      
      
      closes https://github.com/paritytech/polkadot-sdk/issues/1882
      
      ## 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

      @paritytech/ci what would be the best location for that check?  
      It takes only a second to run, so maybe we can squeeze it into one of
