      FRAME: Create `TransactionExtension` as a replacement for `SignedExtension` (#2280) · fd5f9292
      Gavin Wood authored
      
      
      Closes #2160
      
      First part of [Extrinsic
      Horizon](https://github.com/paritytech/polkadot-sdk/issues/2415)
      
      Introduces a new trait `TransactionExtension` to replace
      `SignedExtension`. Introduce the idea of transactions which obey the
      runtime's extensions and have according Extension data (né Extra data)
      yet do not have hard-coded signatures.
      
      Deprecate the terminology of "Unsigned" when used for
      transactions/extrinsics owing to there now being "proper" unsigned
      transactions which obey the extension framework and "old-style" unsigned
      which do not. Instead we have __*General*__ for the former and
      __*Bare*__ for the latter. (Ultimately, the latter will be phased out as
      a type of transaction, and Bare will only be used for Inherents.)
      
      Types of extrinsic are now therefore:
      - Bare (no hardcoded signature, no Extra data; used to be known as
      "Unsigned")
      - Bare transactions (deprecated): Gossiped, validated with
      `ValidateUnsigned` (deprecated) and the `_bare_compat` bits of
      `TransactionExtension` (deprecated).
        - Inherents: Not gossiped, validated with `ProvideInherent`.
      - Extended (Extra data): Gossiped, validated via `TransactionExtension`.
        - Signed transactions (with a hardcoded signature).
        - General transactions (without a hardcoded signature).
      
      `TransactionExtension` differs from `SignedExtension` because:
      - A signature on the underlying transaction may validly not be present.
      - It may alter the origin during validation.
      - `pre_dispatch` is renamed to `prepare` and need not contain the checks
      present in `validate`.
      - `validate` and `prepare` is passed an `Origin` rather than a
      `AccountId`.
      - `validate` may pass arbitrary information into `prepare` via a new
      user-specifiable type `Val`.
      - `AdditionalSigned`/`additional_signed` is renamed to
      `Implicit`/`implicit`. It is encoded *for the entire transaction* and
      passed in to each extension as a new argument to `validate`. This
      facilitates the ability of extensions to acts as underlying crypto.
      
      There is a new `DispatchTransaction` trait which contains only default
      function impls and is impl'ed for any `TransactionExtension` impler. It
      provides several utility functions which reduce some of the tedium from
      using `TransactionExtension` (indeed, none of its regular functions
      should now need to be called directly).
      
      Three transaction version discriminator ("versions") are now
      permissible:
      - 0b000000100: Bare (used to be called "Unsigned"): contains Signature
      or Extra (extension data). After bare transactions are no longer
      supported, this will strictly identify an Inherents only.
      - 0b100000100: Old-school "Signed" Transaction: contains Signature and
      Extra (extension data).
      - 0b010000100: New-school "General" Transaction: contains Extra
      (extension data), but no Signature.
      
      For the New-school General Transaction, it becomes trivial for authors
      to publish extensions to the mechanism for authorizing an Origin, e.g.
      through new kinds of key-signing schemes, ZK proofs, pallet state,
      mutations over pre-authenticated origins or any combination of the
      above.
      
      ## Code Migration
      
      ### NOW: Getting it to build
      
      Wrap your `SignedExtension`s in `AsTransactionExtension`. This should be
      accompanied by renaming your aggregate type in line with the new
      terminology. E.g. Before:
      
      ```rust
      /// The SignedExtension to the basic transaction logic.
      pub type SignedExtra = (
      	/* snip */
      	MySpecialSignedExtension,
      );
      /// Unchecked extrinsic type as expected by this runtime.
      pub type UncheckedExtrinsic =
      	generic::UncheckedExtrinsic<Address, RuntimeCall, Signature, SignedExtra>;
      ```
      
      After:
      
      ```rust
      /// The extension to the basic transaction logic.
      pub type TxExtension = (
      	/* snip */
      	AsTransactionExtension<MySpecialSignedExtension>,
      );
      /// Unchecked extrinsic type as expected by this runtime.
      pub type UncheckedExtrinsic =
      	generic::UncheckedExtrinsic<Address, RuntimeCall, Signature, TxExtension>;
      ```
      
      You'll also need to alter any transaction building logic to add a
      `.into()` to make the conversion happen. E.g. Before:
      
      ```rust
      fn construct_extrinsic(
      		/* snip */
      ) -> UncheckedExtrinsic {
      	let extra: SignedExtra = (
      		/* snip */
      		MySpecialSignedExtension::new(/* snip */),
      	);
      	let payload = SignedPayload::new(call.clone(), extra.clone()).unwrap();
      	let signature = payload.using_encoded(|e| sender.sign(e));
      	UncheckedExtrinsic::new_signed(
      		/* snip */
      		Signature::Sr25519(signature),
      		extra,
      	)
      }
      ```
      
      After:
      
      ```rust
      fn construct_extrinsic(
      		/* snip */
      ) -> UncheckedExtrinsic {
      	let tx_ext: TxExtension = (
      		/* snip */
      		MySpecialSignedExtension::new(/* snip */).into(),
      	);
      	let payload = SignedPayload::new(call.clone(), tx_ext.clone()).unwrap();
      	let signature = payload.using_encoded(|e| sender.sign(e));
      	UncheckedExtrinsic::new_signed(
      		/* snip */
      		Signature::Sr25519(signature),
      		tx_ext,
      	)
      }
      ```
      
      ### SOON: Migrating to `TransactionExtension`
      
      Most `SignedExtension`s can be trivially converted to become a
      `TransactionExtension`. There are a few things to know.
      
      - Instead of a single trait like `SignedExtension`, you should now
      implement two traits individually: `TransactionExtensionBase` and
      `TransactionExtension`.
      - Weights are now a thing and must be provided via the new function `fn
      weight`.
      
      #### `TransactionExtensionBase`
      
      This trait takes care of anything which is not dependent on types
      specific to your runtime, most notably `Call`.
      
      - `AdditionalSigned`/`additional_signed` is renamed to
      `Implicit`/`implicit`.
      - Weight must be returned by implementing the `weight` function. If your
      extension is associated with a pallet, you'll probably want to do this
      via the pallet's existing benchmarking infrastructure.
      
      #### `TransactionExtension`
      
      Generally:
      - `pre_dispatch` is now `prepare` and you *should not reexecute the
      `validate` functionality in there*!
      - You don't get an account ID any more; you get an origin instead. If
      you need to presume an account ID, then you can use the trait function
      `AsSystemOriginSigner::as_system_origin_signer`.
      - You get an additional ticket, similar to `Pre`, called `Val`. This
      defines data which is passed from `validate` into `prepare`. This is
      important since you should not be duplicating logic from `validate` to
      `prepare`, you need a way of passing your working from the former into
      the latter. This is it.
      - This trait takes two type parameters: `Call` and `Context`. `Call` is
      the runtime call type which used to be an associated type; you can just
      move it to become a type parameter for your trait impl. `Context` is not
      currently used and you can safely implement over it as an unbounded
      type.
      - There's no `AccountId` associated type any more. Just remove it.
      
      Regarding `validate`:
      - You get three new parameters in `validate`; all can be ignored when
      migrating from `SignedExtension`.
      - `validate` returns a tuple on success; the second item in the tuple is
      the new ticket type `Self::Val` which gets passed in to `prepare`. If
      you use any information extracted during `validate` (off-chain and
      on-chain, non-mutating) in `prepare` (on-chain, mutating) then you can
      pass it through with this. For the tuple's last item, just return the
      `origin` argument.
      
      Regarding `prepare`:
      - This is renamed from `pre_dispatch`, but there is one change:
      - FUNCTIONALITY TO VALIDATE THE TRANSACTION NEED NOT BE DUPLICATED FROM
      `validate`!!
      - (This is different to `SignedExtension` which was required to run the
      same checks in `pre_dispatch` as in `validate`.)
      
      Regarding `post_dispatch`:
      - Since there are no unsigned transactions handled by
      `TransactionExtension`, `Pre` is always defined, so the first parameter
      is `Self::Pre` rather than `Option<Self::Pre>`.
      
      If you make use of `SignedExtension::validate_unsigned` or
      `SignedExtension::pre_dispatch_unsigned`, then:
      - Just use the regular versions of these functions instead.
      - Have your logic execute in the case that the `origin` is `None`.
      - Ensure your transaction creation logic creates a General Transaction
      rather than a Bare Transaction; this means having to include all
      `TransactionExtension`s' data.
      - `ValidateUnsigned` can still be used (for now) if you need to be able
      to construct transactions which contain none of the extension data,
      however these will be phased out in stage 2 of the Transactions Horizon,
      so you should consider moving to an extension-centric design.
      
      ## TODO
      
      - [x] Introduce `CheckSignature` impl of `TransactionExtension` to
      ensure it's possible to have crypto be done wholly in a
      `TransactionExtension`.
      - [x] Deprecate `SignedExtension` and move all uses in codebase to
      `TransactionExtension`.
        - [x] `ChargeTransactionPayment`
        - [x] `DummyExtension`
        - [x] `ChargeAssetTxPayment` (asset-tx-payment)
        - [x] `ChargeAssetTxPayment` (asset-conversion-tx-payment)
        - [x] `CheckWeight`
        - [x] `CheckTxVersion`
        - [x] `CheckSpecVersion`
        - [x] `CheckNonce`
        - [x] `CheckNonZeroSender`
        - [x] `CheckMortality`
        - [x] `CheckGenesis`
        - [x] `CheckOnlySudoAccount`
        - [x] `WatchDummy`
        - [x] `PrevalidateAttests`
        - [x] `GenericSignedExtension`
        - [x] `SignedExtension` (chain-polkadot-bulletin)
        - [x] `RefundSignedExtensionAdapter`
      - [x] Implement `fn weight` across the board.
      - [ ] Go through all pre-existing extensions which assume an account
      signer and explicitly handle the possibility of another kind of origin.
      - [x] `CheckNonce` should probably succeed in the case of a non-account
      origin.
      - [x] `CheckNonZeroSender` should succeed in the case of a non-account
      origin.
      - [x] `ChargeTransactionPayment` and family should fail in the case of a
      non-account origin.
        - [ ] 
      - [x] Fix any broken tests.

      Multi-Block-Migrations, `poll` hook and new System callbacks (#1781) · eefd5fe4
      Oliver Tale-Yazdi authored
      
      
      This MR is the merge of
      https://github.com/paritytech/substrate/pull/14414 and
      https://github.com/paritytech/substrate/pull/14275. It implements
      [RFC#13](https://github.com/polkadot-fellows/RFCs/pull/13), closes
      https://github.com/paritytech/polkadot-sdk/issues/198.
      
      ----- 
      
      This Merge request introduces three major topicals:
      
      1. Multi-Block-Migrations
      1. New pallet `poll` hook for periodic service work
      1. Replacement hooks for `on_initialize` and `on_finalize` in cases
      where `poll` cannot be used
      
      and some more general changes to FRAME.  
      The changes for each topical span over multiple crates. They are listed
      in topical order below.
      
      # 1.) Multi-Block-Migrations
      
      Multi-Block-Migrations are facilitated by creating `pallet_migrations`
      and configuring `System::Config::MultiBlockMigrator` to point to it.
      Executive picks this up and triggers one step of the migrations pallet
      per block.
      The chain is in lockdown mode for as long as an MBM is ongoing.
      Executive does this by polling `MultiBlockMigrator::ongoing` and not
      allowing any transaction in a block, if true.
      
      A MBM is defined through trait `SteppedMigration`. A condensed version
      looks like this:
      ```rust
      /// A migration that can proceed in multiple steps.
      pub trait SteppedMigration {
      	type Cursor: FullCodec + MaxEncodedLen;
      	type Identifier: FullCodec + MaxEncodedLen;
      
      	fn id() -> Self::Identifier;
      
      	fn max_steps() -> Option<u32>;
      
      	fn step(
      		cursor: Option<Self::Cursor>,
      		meter: &mut WeightMeter,
      	) -> Result<Option<Self::Cursor>, SteppedMigrationError>;
      }
      ```
      
      `pallet_migrations` can be configured with an aggregated tuple of these
      migrations. It then starts to migrate them one-by-one on the next
      runtime upgrade.
      Two things are important here:
      - 1. Doing another runtime upgrade while MBMs are ongoing is not a good
      idea and can lead to messed up state.
      - 2. **Pallet Migrations MUST BE CONFIGURED IN `System::Config`,
      otherwise it is not used.**
      
      The pallet supports an `UpgradeStatusHandler` that can be used to notify
      external logic of upgrade start/finish (for example to pause XCM
      dispatch).
      
      Error recovery is very limited in the case that a migration errors or
      times out (exceeds its `max_steps`). Currently the runtime dev can
      decide in `FailedMigrationHandler::failed` how to handle this. One
      follow-up would be to pair this with the `SafeMode` pallet and enact
      safe mode when an upgrade fails, to allow governance to rescue the
      chain. This is currently not possible, since governance is not
      `Mandatory`.
      
      ## Runtime API
      
      - `Core`: `initialize_block` now returns `ExtrinsicInclusionMode` to
      inform the Block Author whether they can push transactions.
      
      ### Integration
      
      Add it to your runtime implementation of `Core` and `BlockBuilder`:
      ```patch
      diff --git a/runtime/src/lib.rs b/runtime/src/lib.rs
      @@ impl_runtime_apis! {
      	impl sp_block_builder::Core<Block> for Runtime {
      -		fn initialize_block(header: &<Block as BlockT>::Header) {
      +		fn initialize_block(header: &<Block as BlockT>::Header) -> RuntimeExecutiveMode {
      			Executive::initialize_block(header)
      		}
      
      		...
      	}
      ```
      
      # 2.) `poll` hook
      
      A new pallet hook is introduced: `poll`. `Poll` is intended to replace
      mostly all usage of `on_initialize`.
      The reason for this is that any code that can be called from
      `on_initialize` cannot be migrated through an MBM. Currently there is no
      way to statically check this; the implication is to use `on_initialize`
      as rarely as possible.
      Failing to do so can result in broken storage invariants.
      
      The implementation of the poll hook depends on the `Runtime API` changes
      that are explained above.
      
      # 3.) Hard-Deadline callbacks
      
      Three new callbacks are introduced and configured on `System::Config`:
      `PreInherents`, `PostInherents` and `PostTransactions`.
      These hooks are meant as replacement for `on_initialize` and
      `on_finalize` in cases where the code that runs cannot be moved to
      `poll`.
      The reason for this is to make the usage of HD-code (hard deadline) more
      explicit - again to prevent broken invariants by MBMs.
      
      # 4.) FRAME (general changes)
      
      ## `frame_system` pallet
      
      A new memorize storage item `InherentsApplied` is added. It is used by
      executive to track whether inherents have already been applied.
      Executive and can then execute the MBMs directly between inherents and
      transactions.
      
      The `Config` gets five new items:
      - `SingleBlockMigrations` this is the new way of configuring migrations
      that run in a single block. Previously they were defined as last generic
      argument of `Executive`. This shift is brings all central configuration
      about migrations closer into view of the developer (migrations that are
      configured in `Executive` will still work for now but is deprecated).
      - `MultiBlockMigrator` this can be configured to an engine that drives
      MBMs. One example would be the `pallet_migrations`. Note that this is
      only the engine; the exact MBMs are injected into the engine.
      - `PreInherents` a callback that executes after `on_initialize` but
      before inherents.
      - `PostInherents` a callback that executes after all inherents ran
      (including MBMs and `poll`).
      - `PostTransactions` in symmetry to `PreInherents`, this one is called
      before `on_finalize` but after all transactions.
      
      A sane default is to set all of these to `()`. Example diff suitable for
      any chain:
      ```patch
      @@ impl frame_system::Config for Test {
       	type MaxConsumers = ConstU32<16>;
      +	type SingleBlockMigrations = ();
      +	type MultiBlockMigrator = ();
      +	type PreInherents = ();
      +	type PostInherents = ();
      +	type PostTransactions = ();
       }
      ```

      graph is also in the rust doc.

      [pallet-xcm] Adjust benchmarks (teleport_assets/reserve_transfer_assets) not relying on ED (#3464) · 3d9439f6
      Branislav Kontur authored
      
      
      ## Problem
      During the bumping of the `polkadot-fellows` repository to
      `[email protected]`, I encountered a situation where the benchmarks
      `teleport_assets` and `reserve_transfer_assets` in AssetHubKusama
      started to fail. This issue arose due to a decreased ED balance for
      AssetHubs introduced
      [here](https://github.com/polkadot-fellows/runtimes/pull/158/files#diff-80668ff8e793b64f36a9a3ec512df5cbca4ad448c157a5d81abda1b15f35f1daR213),
      and also because of a [missing CI
      pipeline](https://github.com/polkadot-fellows/runtimes/issues/197) to
      check the benchmarks, which went unnoticed.
      
      These benchmarks expect the `caller` to have enough:
      1. balance to transfer (BTT)
      2. balance for paying delivery (BFPD).
       
      So the initial balance was calculated as `ED * 100`, which seems
      reasonable:
      ```
      const ED_MULTIPLIER: u32 = 100;
      let balance = existential_deposit.saturating_mul(ED_MULTIPLIER.into());`
      ```
      The problem arises when the price for delivery is 100 times higher than
      the existential deposit. In other words, when `ED * 100` does not cover
      `BTT` + `BFPD`.
      
      I check AHR/AHW/AHK/AHP and this problem has only AssetHubKusama
      ```
      ED: 3333333
      calculated price to parent delivery:  1031666634  (from xcm logs from the benchmark)
      ---
      
      3333333 * 100 - BTT(3333333) - BFPD(1031666634) = −701666667
      ```
      which results in the error;
      ```
      2024-02-23 09:19:42 Unable to charge fee with error Module(ModuleError { index: 31, error: [17, 0, 0, 0], message: Some("FeesNotMet") })
      Error: Input("Benchmark pallet_xcm::reserve_transfer_assets failed: FeesNotMet")
           
      ```
      
      ## Solution
      
      The benchmarks `teleport_assets` and `reserve_transfer_assets` were
      fixed by removing `ED * 100` and replacing it with `DeliveryHelper`
      logic, which calculates the (almost real) price for delivery and sets it
      along with the existential deposit as the initial balance for the
      account used in the benchmark.

      Add retry mechanics to `pallet-scheduler` (#3060) · 9346019d
      georgepisaltu authored
      
      
      Fixes #3014 
      
      This PR adds retry mechanics to `pallet-scheduler`, as described in the
      issue above.
      
      Users can now set a retry configuration for a task so that, in case its
      scheduled run fails, it will be retried after a number of blocks, for a
      specified number of times or until it succeeds.
      
      If a retried task runs successfully before running out of retries, its
      remaining retry counter will be reset to the initial value. If a retried
      task runs out of retries, it will be removed from the schedule.
      
      Tasks which need to be scheduled for a retry are still subject to weight
      metering and agenda space, same as a regular task. Periodic tasks will
      have their periodic schedule put on hold while the task is retrying.

      Ranked collective `Add`+`Remove` origins (#3212) · c552fb54
      Oliver Tale-Yazdi authored
      
      
      Superseeds https://github.com/paritytech/polkadot-sdk/pull/1245  
      
      This PR is a migration of the
      https://github.com/paritytech/substrate/pull/14577.
      
      The PR added associated types (`AddOrigin` & `RemoveOrigin`) to
      `Config`. It allows you to decouple types and areas of responsibility,
      since at the moment the same types are responsible for adding and
      promoting(removing and demoting). This will improve the flexibility of
      the pallet configuration.
      
      ```
      /// The origin required to add a member.
      type AddOrigin: EnsureOrigin<Self::RuntimeOrigin, Success = ()>;
      
      /// The origin required to remove a member. The success value indicates the
      /// maximum rank *from which* the removal may be.
      type RemoveOrigin: EnsureOrigin<Self::RuntimeOrigin, Success = Rank>;
      ```
      To achieve the backward compatibility, the users of the pallet can use
      the old type via the new morph:
      
      ```
      type AddOrigin = MapSuccess<Self::PromoteOrigin, Ignore>;
      type RemoveOrigin = Self::DemoteOrigin;
      ```

      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`.

      - Limit the number of channels that can have messages or signals pending
      at the same time.
      
      A No-OP migration is put in place to ensure that all `BoundedVec`s still
      decode and not truncate after upgrade. The storage version is thereby
      bumped to 4 to have our tooling remind us to deploy that migration.

      --- 
      This PR introduces transactional processing of certain xcm instructions.
      For the list of instructions checkout
      https://github.com/paritytech/polkadot-sdk/issues/490. The transactional
      processing is implemented as an xcm-executor config item. The two
      implementations in this PR are `FrameTransactionalProcessor` and `()`.
      The `()` implementation does no transactional processing. Each
      implementation of the `ProcessTransaction` trait has an
      `IS_TRANSACTIONAL` const that tells the XCVM if transactional processing
      is actually implemented. If Transactional processing is implemented,
      changes to touched registers should also be rolled back to prevent
      inconsistencies.
      
      
      Note for reviewers:

      XCMv4 (#1230) · 8428f678
      Francisco Aguirre authored
      
      
      # Note for reviewer
      
      Most changes are just syntax changes necessary for the new version.
      Most important files should be the ones under the `xcm` folder.
      
      # Description 
      
      Added XCMv4.
      
      ## Removed `Multi` prefix
      The following types have been renamed:
      - MultiLocation -> Location
      - 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

      joe petrowski authored
      
      
      Rococo and Westend runtimes for the "People Chain". This chain contains
      the Identity pallet with plans to migrate all related data from the
      Relay Chain.
      
      Changes `IdentityInfo` to:
      
      - Remove `additional_fields`.
      - Add `github` and `discord` as first class fields. From scraping chain
      data, these were the only two additional fields used (for the Fellowship
      and Ambassador Program, respectively).
      - Rename `riot` to `matrix`.
      
      Note: This will use the script in
      https://github.com/paritytech/polkadot-sdk/pull/2025 to generate the
      genesis state.
      
      TODO:
      
      - [x] https://github.com/paritytech/polkadot-sdk/pull/1814 and
      integration of the Identity Migrator pallet for migration.

      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 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.

      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
      ```

      Westend: Fellowship Treasury (#2532) · da40d97a
      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.

      Remove `testnets-common` (#2620) · 814b938d
      Dónal Murray authored
      `testnets-common` was introduced recently to start to separate testnet
      parachain configurations from those of Polkadot and Kusama.
      
      The `locks-review` and `polkadot-review` requirements are removed from
      `parachains-common` in
      https://github.com/paritytech/polkadot-sdk/pull/2564 and there are
      [plans](https://github.com/paritytech/polkadot-sdk/pull/2564#discussion_r1410882115)
      to move the Polkadot and Kusama contents of that package to the
      fellowship, `testnets-common` is no longer needed.
      
      This PR removes the crate and replaces uses of it in
      `collectives-westend`, the only place it is currently used.

      As suggested in this thread:
      https://github.com/polkadot-fellows/runtimes/pull/87#discussion_r1400237122
      
      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.

      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`.
