      Integrate litep2p into Polkadot SDK (#2944) · 80616f6d
      Aaro Altonen authored
      [litep2p](https://github.com/altonen/litep2p) is a libp2p-compatible P2P
      networking library. It supports all of the features of `rust-libp2p`
      that are currently being utilized by Polkadot SDK.
      
      Compared to `rust-libp2p`, `litep2p` has a quite different architecture
      which is why the new `litep2p` network backend is only able to use a
      little of the existing code in `sc-network`. The design has been mainly
      influenced by how we'd wish to structure our networking-related code in
      Polkadot SDK: independent higher-levels protocols directly communicating
      with the network over links that support bidirectional backpressure. A
      good example would be `NotificationHandle`/`RequestResponseHandle`
      abstractions which allow, e.g., `SyncingEngine` to directly communicate
      with peers to announce/request blocks.
      
      I've tried running `polkadot --network-backend litep2p` with a few
      different peer configurations and there is a noticeable reduction in
      networking CPU usage. For high load (`...

      [FRAME] Runtime Omni Bencher (#3512) · 9543d314
      Oliver Tale-Yazdi authored
      
      
      This MR contains two major changes and some maintenance cleanup.  
      
      ## 1. Free Standing Pallet Benchmark Runner
      
      Closes https://github.com/paritytech/polkadot-sdk/issues/3045, depends
      on your runtime exposing the `GenesisBuilderApi` (like
      https://github.com/paritytech/polkadot-sdk/pull/1492).
      
      Introduces a new binary crate: `frame-omni-bencher`.  
      It allows to directly benchmark a WASM blob - without needing a node or
      chain spec.
      
      This makes it much easier to generate pallet weights and should allow us
      to remove bloaty code from the node.
      It should work for all FRAME runtimes that dont use 3rd party host calls
      or non `BlakeTwo256` block hashing (basically all polkadot parachains
      should work).
      
      It is 100% backwards compatible with the old CLI args, when the `v1`
      compatibility command is used. This is done to allow for forwards
      compatible addition of new commands.
      
      ### Example (full example in the Rust docs)
      
      Installing the CLI:
      ```sh
      cargo install --locked --path substrate/utils/frame/omni-bencher
      frame-omni-bencher --help
      ```
      
      Building the Westend runtime:
      ```sh
      cargo build -p westend-runtime --release --features runtime-benchmarks
      ```
      
      Benchmarking the runtime:
      ```sh
      frame-omni-bencher v1 benchmark pallet --runtime target/release/wbuild/westend-runtime/westend_runtime.compact.compressed.wasm --all
      ```
      
      ## 2. Building the Benchmark Genesis State in the Runtime
      
      Closes https://github.com/paritytech/polkadot-sdk/issues/2664
      
      This adds `--runtime` and `--genesis-builder=none|runtime|spec`
      arguments to the `benchmark pallet` command to make it possible to
      generate the genesis storage by the runtime. This can be used with both
      the node and the freestanding benchmark runners. It utilizes the new
      `GenesisBuilder` RA and depends on having
      https://github.com/paritytech/polkadot-sdk/pull/3412 deployed.
      
      ## 3. Simpler args for `PalletCmd::run`
      
      You can do three things here to integrate the changes into your node:
      - nothing: old code keeps working as before but emits a deprecated
      warning
      - delete: remove the pallet benchmarking code from your node and use the
      omni-bencher instead
      - patch: apply the patch below and keep using as currently. This emits a
      deprecated warning at runtime, since it uses the old way to generate a
      genesis state, but is the smallest change.
      
      ```patch
      runner.sync_run(|config| cmd
      -    .run::<HashingFor<Block>, ReclaimHostFunctions>(config)
      +    .run_with_spec::<HashingFor<Block>, ReclaimHostFunctions>(Some(config.chain_spec))
      )
      ```
      
      ## 4. Maintenance Change
      - `pallet-nis` get a `BenchmarkSetup` config item to prepare its
      counterparty asset.
      - Add percent progress print when running benchmarks.
      - Dont immediately exit on benchmark error but try to run as many as
      possible and print errors last.

      `GenesisConfig` presets for runtime (#2714) · f910a15c
      Michal Kucharczyk authored
      The runtime now can provide a number of predefined presets of
      `RuntimeGenesisConfig` struct. This presets are intended to be used in
      different deployments, e.g.: `local`, `staging`, etc, and should be
      included into the corresponding chain-specs.
      
      Having `GenesisConfig` presets in runtime allows to fully decouple node
      from runtime types (the problem is described in #1984).
      
      **Summary of changes:**
      - The `GenesisBuilder` API was adjusted to enable this functionality
      (and provide better naming - #150):
         ```rust
          fn preset_names() -> Vec<PresetId>;
      fn get_preset(id: Option<PresetId>) -> Option<serde_json::Value>;
      //`None` means default
          fn build_state(value: serde_json::Value);
          pub struct PresetId(Vec<u8>);
         ```
      
      - **Breaking change**: Old `create_default_config` method was removed,
      `build_config` was renamed to `build_state`. As a consequence a node
      won't be able to interact with genesis config for older runtimes. The
      cleanup was made for sake of API simplicity. Also IMO maintaining
      compatibility with old API is not so crucial.
      - Reference implementation was provided for `substrate-test-runtime` and
      `rococo` runtimes. For rococo new
      [`genesis_configs_presets`](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/polkadot/runtime/rococo/src/genesis_config_presets.rs#L530)
      module was added and is used in `GenesisBuilder`
      [_presets-related_](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/polkadot/runtime/rococo/src/lib.rs#L2462-L2485)
      methods.
      
      - The `chain-spec-builder` util was also improved and allows to
      ([_doc_](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/substrate/bin/utils/chain-spec-builder/src/lib.rs#L19)):
         - list presets provided by given runtime (`list-presets`),
      - display preset or default config provided by the runtime
      (`display-preset`),
         - build chain-spec using named preset (`create ... named-preset`),
      
      
      - The `ChainSpecBuilder` is extended with
      [`with_genesis_config_preset_name`](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/substrate/client/chain-spec/src/chain_spec.rs#L447)
      method which allows to build chain-spec using named preset provided by
      the runtime. Sample usage on the node side
      [here](https://github.com/paritytech/polkadot-sdk/blob/2caffaae
      
      /polkadot/node/service/src/chain_spec.rs#L404).
      
      Implementation of #1984.

      Revert "FRAME: Create `TransactionExtension` as a replacement for `SignedExtension` (#2280)" (#3665)
      
      This PR reverts #2280 which introduced `TransactionExtension` to replace
      `SignedExtension`.
      
      As a result of the discussion
      [here](https://github.com/paritytech/polkadot-sdk/pull/3623#issuecomment-1986789700),
      the changes will be reverted for now with plans to reintroduce the
      concept in the future.

      Construct Runtime v2 (#1378) · 82f3c3e2

      Moved from https://github.com/paritytech/substrate/pull/14788
      
      ----
      
      Fixes https://github.com/paritytech/polkadot-sdk/issues/232
      
      This PR introduces outer-macro approach for `construct_runtime` as
      discussed in the linked issue. It looks like the following:
      ```rust
      #[frame_support::runtime]
      mod runtime {
      	#[runtime::runtime]
              #[runtime::derive(
      		RuntimeCall,
      		RuntimeEvent,
      		RuntimeError,
      		RuntimeOrigin,
      		RuntimeFreezeReason,
      		RuntimeHoldReason,
      		RuntimeSlashReason,
      		RuntimeLockId,
                      RuntimeTask,
      	)]
      	pub struct Runtime;
      
      	#[runtime::pallet_index(0)]
      	pub type System = frame_system;
      
      	#[runtime::pallet_index(1)]
      	pub type Timestamp = pallet_timestamp;
      
      	#[runtime::pallet_index(2)]
      	pub type Aura = pallet_aura;
      
      	#[runtime::pallet_index(3)]
      	pub type Grandpa = pallet_grandpa;
      
      	#[runtime::pallet_index(4)]
      	pub type Balances = pallet_balances;
      
      	#[runtime::pallet_index(5)]
      	pub type TransactionPayment = pallet_transaction_payment;
      
      	#[runtime::pallet_index(6)]
      	pub type Sudo = pallet_sudo;
      
      	// Include the custom logic from the pallet-template in the runtime.
      	#[runtime::pallet_index(7)]
      	pub type TemplateModule = pallet_template;
      }
      ```
      
      ## Features
      - `#[runtime::runtime]` attached to a struct defines the main runtime
      - `#[runtime::derive]` attached to this struct defines the types
      generated by runtime
      - `#[runtime::pallet_index]` must be attached to a pallet to define its
      index
      - `#[runtime::disable_call]` can be optionally attached to a pallet to
      disable its calls
      - `#[runtime::disable_unsigned]` can be optionally attached to a pallet
      to disable unsigned calls
      - A pallet instance can be defined as `TemplateModule:
      pallet_template<Instance>`
      - An optional attribute can be defined as
      `#[frame_support::runtime(legacy_ordering)]` to ensure that the order of
      hooks is same as the order of pallets (and not based on the
      pallet_index). This is to support legacy runtimes and should be avoided
      for new ones.
      
      ## Todo
      - [x] Update the latest syntax in kitchensink and tests
      - [x] Update UI tests
      - [x] Docs
      
      ## Extension
      - Abstract away the Executive similar to
      https://github.com/paritytech/substrate/pull/14742
      - Optionally avoid the need to specify all runtime types (TBD)

      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 = ();
       }
      ```
      
      An overview of how the block execution now looks like is here. The same
      graph is also in the rust doc.

      rpc server: make possible to disable/enable batch requests (#3364) · fee810a5
      Niklas Adolfsson authored
      The rationale behind this, is that it may be useful for some users
      actually disable RPC batch requests or limit them by length instead of
      the total size bytes of the batch.
      
      This PR adds two new CLI options:
      
      ```
      --rpc-disable-batch-requests - disable batch requests on the server
      --rpc-max-batch-request-len <LEN> - limit batches to LEN on the server.
      ```

      Lift dependencies to the workspace (Part 2/x) (#3366) · e89d0fca
      Oliver Tale-Yazdi authored
      
      
      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
      ```

      Add broker pallet to `coretime-westend` (#3272) · 99234440
      Dónal Murray authored
      
      
      This brings functionality to Westend's Coretime Chain runtime, where
      previously it was not much more than a shell.
      
      It is assumed that the Coretime pallet will have the same index in the
      Westend runtime as it does in Rococo for the runtime calls.
      
      TODO:
      - [x] Generate chainspec
      - [x] Regenerate weights
      - [x] Check hardcoded RuntimeCall weights against relay weights for
      transacts

      Lift dependencies to the workspace (Part 1) (#2070) · e80c2473
      Oliver Tale-Yazdi authored
      Changes (partial https://github.com/paritytech/polkadot-sdk/issues/994):
      - Set log to `0.4.20` everywhere
      - Lift `log` to the workspace
      
      Starting with a simpler one after seeing
      https://github.com/paritytech/polkadot-sdk/pull/2065 from @jsdw
      
      .
      This sets the `default-features` to `false` in the root and then
      overwrites that in each create to its original value. This is necessary
      since otherwise the `default` features are additive and its impossible
      to disable them in the crate again once they are enabled in the
      workspace.
      
      I am using a tool to do this, so its mostly a test to see that it works
      as expected.

      [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)
      	}
      }
      ```

      `bench pallet`: only require `Hash` instead of `Block` (#3244) · c36c51ca
      Oliver Tale-Yazdi authored
      
      
      Preparation for https://github.com/paritytech/polkadot-sdk/issues/2664
      
      Changes:
      - Only require `Hash` instead of `Block` for the benchmarking
      - Refactor DB types to do the same
      
      ## Integration
      
      This breaking change can easily be integrated into your node via:  
      ```patch
      - cmd.run::<Block, ()>(config)
      + cmd.run::<HashingFor<Block>, ()>(config)
      ```
      
      Status: waiting for CI checks

      Ranked collective `Add`+`Remove` origins (#3212) · c552fb54

      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;
      ```

      [FRAME] Make `core-fellowship` ans `salary` work for swapped members (#3156) · 07e55006
      Oliver Tale-Yazdi authored
      Fixup for https://github.com/paritytech/polkadot-sdk/pull/2587 to make
      the `core-fellowship` crate work with swapped members.
      
      Adds a `MemberSwappedHandler` to the `ranked-collective` pallet that are
      implemented by `core-fellowship+salary`.
      There is are exhaustive tests
      [here](https://github.com/paritytech/polkadot-sdk/blob/72aa7ac1/substrate/frame/core-fellowship/src/tests/integration.rs#L338)
      and
      [here](https://github.com/paritytech/polkadot-sdk/blob/ab3cdb05
      
      /substrate/frame/salary/src/tests/integration.rs#L224)
      to check that adding member `1` is equivalent to adding member `0` and
      then swapping.

      [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`.
