      ParaInherent create: update `apply_weight_limit` wrt elastic scaling (#3573) · c16fcc47
      Andrei Sandu authored
      
      
      Changes the way we perform the random selection of backed candidates
      when there isn't enough room for all of them. Instead of picking
      individual backed candidates `apply_weight` now operates on chains of
      candidates. This is fully backwards compatible and relies on the node
      side (provisioner/prospective parachains) doing the heavy lifting and
      providing the candidates in the order they form a chain.
      
      The same approach can be implemented for bitfields random selection once
      https://github.com/paritytech/polkadot-sdk/pull/3479 is merged.
      
      The approach taken in this PR aims for reduced additional complexity at
      the cost of being less fair wrt how many backed candidates from each
      chain are picked. It favors elastic scaling parachains vs parachains not
      using elastic scaling, but from my perspective it should be fine as this
      should happen under exceptional circumstances like dispute storms.
      
      Note: to make things more fair we can consider specializing `random_sel`
      such that it will try to pick candidates one by one in the order
      provided by the provisioner such that non elastic scaling parachains
      have the same chance of getting a candidate backed.

      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.

      provisioner: allow multiple cores assigned to the same para (#3233) · 62b78a16
      Alin Dima authored
      https://github.com/paritytech/polkadot-sdk/issues/3130
      
      builds on top of https://github.com/paritytech/polkadot-sdk/pull/3160
      
      Processes the availability cores and builds a record of how many
      candidates it should request from prospective-parachains and their
      predecessors.
      Tries to supply as many candidates as the runtime can back. Note that
      the runtime changes to back multiple candidates per para are not yet
      done, but this paves the way for it.
      
      The following backing/inclusion policy is assumed:
      1. the runtime will never back candidates of the same para which don't
      form a chain with the already backed candidates. Even if the others are
      still pending availability. We're optimistic that they won't time out
      and we don't want to back parachain forks (as the complexity would be
      huge).
      2. if a candidate is timed out of the core before being included, all of
      its successors occupying a core will be evicted.
      3. only the candidates which are made available and form a chain
      starting from the on-chain para head may be included/enacted and cleared
      from the cores. In other words, if para head is at A and the cores are
      occupied by B->C->D, and B and D are made available, only B will be
      included and its core cleared. C and D will remain on the cores awaiting
      for C to be made available or timed out. As point (2) above already
      says, if C is timed out, D will also be dropped.
      4. The runtime will deduplicate candidates which form a cycle. For
      example if the provisioner supplies candidates A->B->A, the runtime will
      only back A (as the state output will be the same)
      
      Note that if a candidate is timed out, we don't guarantee that in the
      next relay chain block the block author will be able to fill all of the
      timed out cores of the para. That increases complexity by a lot.
      Instead, the provisioner will supply N candidates where N is the number
      of candidates timed out, but doesn't include their successors which will
      be also deleted by the runtime. This'll be backfilled in the next relay
      chain block.
      
      Adjacent changes:
      - Also fixes: https://github.com/paritytech/polkadot-sdk/issues/3141
      - For non prospective-parachains, don't supply multiple candidates per
      para (we can't have elastic scaling without prospective parachains
      enabled). paras_inherent should already sanitise this input but it's
      more efficient this way.
      
      Note: all of these changes are backwards-compatible with the
      non-elastic-scaling scenario (one core per para).

      subsystem-bench: add regression tests for availability read and write (#3311) · f0e589d7
      Andrei Eres authored
      
      
      ### What's been done
      - `subsystem-bench` has been split into two parts: a cli benchmark
      runner and a library.
      - The cli runner is quite simple. It just allows us to run `.yaml` based
      test sequences. Now it should only be used to run benchmarks during
      development.
      - The library is used in the cli runner and in regression tests. Some
      code is changed to make the library independent of the runner.
      - Added first regression tests for availability read and write that
      replicate existing test sequences.
      
      ### How we run regression tests
      - Regression tests are simply rust integration tests without the
      harnesses.
      - They should only be compiled under the `subsystem-benchmarks` feature
      to prevent them from running with other tests.
      - This doesn't work when running tests with `nextest` in CI, so
      additional filters have been added to the `nextest` runs.
      - Each benchmark run takes a different time in the beginning, so we
      "warm up" the tests until their CPU usage differs by only 1%.
      - After the warm-up, we run the benchmarks a few more times and compare
      the average with the exception using a precision.
      
      ### What is still wrong?
      - I haven't managed to set up approval voting tests. The spread of their
      results is too large and can't be narrowed down in a reasonable amount
      of time in the warm-up phase.
      - The tests start an unconfigurable prometheus endpoint inside, which
      causes errors because they use the same 9999 port. I disable it with a
      flag, but I think it's better to extract the endpoint launching outside
      the test, as we already do with `valgrind` and `pyroscope`. But we still
      use `prometheus` inside the tests.

      Add `claim_assets` extrinsic to `pallet-xcm` (#3403) · 65088668
      Francisco Aguirre authored
      
      
      If an XCM execution fails or ends with leftover assets, these will be
      trapped.
      In order to claim them, a custom XCM has to be executed, with the
      `ClaimAsset` instruction.
      However, arbitrary XCM execution is not allowed everywhere yet and XCM
      itself is still not easy enough to use for users out there with trapped
      assets.
      This new extrinsic in `pallet-xcm` will allow these users to easily
      claim their assets, without concerning themselves with writing arbitrary
      XCMs.

      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.

      - Changes 'current storage version' terminology to less ambiguous
      'in-code storage version' (suggestion by @ggwpez
      
      )
      - Adds a new example pallet `pallet-example-single-block-migrations`

      - Adds documentation for the `storage_alias` macro
      - Improves `trait Hooks` docs 
      - Improves `trait GetStorageVersion` docs

      - Unversioned migration code is kept inside `mod version_unchecked`,
      versioned code is kept in `pub mod versioned`
      - It is necessary to use modules to limit visibility because the inner
      migration must be `pub`. See

      Add Polkadotters bootnoders per IBP application (#3423) · 0cc9b900
      Petr Mensik authored
      Hey everyone,
      
      this PR will replace existing Polkadotters bootnodes for Polkadot,
      Kusama and Westend and add Paseo bootnode to the relay chain suite. At
      the same time, it will add new bootnodes for all the system parachains,
      including People on Westend. This PR is a part of our membership in the
      IBP, meaning that all the bootnodes are hosted on our hardware housed in
      the data center in Christchurch, New Zealand.
      All the bootnodes were tested with an empty chain spec file with the

      [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
      ```

      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 more debug logs to understand if statement-distribution is in a bad
      state, should be useful for debugging
      https://github.com/paritytech/polkadot-sdk/issues/3314 on production
      networks.
      
      Additionally, increase the number of parallel requests should make,
      since I notice that requests take around 100ms on kusama, and the 5
      parallel request was picked mostly random, no reason why we can do more
      than that.

      Runtime: allow backing multiple candidates of same parachain on different cores (#3231) · 2431001e
      Andrei Sandu authored
      
      
      Fixes https://github.com/paritytech/polkadot-sdk/issues/3144
      
      Builds on top of https://github.com/paritytech/polkadot-sdk/pull/3229
      
      ### Summary
      Some preparations for Runtime to support elastic scaling, guarded by
      config node features bit `FeatureIndex::ElasticScalingMVP`. This PR
      introduces a per-candidate `CoreIndex` but does it in a hacky way to
      avoid changing `CandidateCommitments`, `CandidateReceipts` primitives
      and networking protocols.
      
      #### Including `CoreIndex` in `BackedCandidate`
      If the `ElasticScalingMVP` feature bit is enabled then
      `BackedCandidate::validator_indices` is extended by 8 bits.
      The value stored in these bits represents the assumed core index for the
      candidate.
      
      It is temporary solution which works by creating a mapping from
      `BackedCandidate` to `CoreIndex` by assuming the `CoreIndex` can be
      discovered by checking in which validator group the validator that
      signed the statement is.
      
      TODO:
      - [x] fix tests
      - [x] add new tests
      - [x] Bump runtime API for Kusama, so we have that node features thing!

      Check that the validation code matches the parachain code (#3433) · 9bf1a5e2

      This introduces a check to ensure that the parachain code matches the
      validation code stored in the relay chain state. If not, it will print a
      warning. This should be mainly useful for parachain builders to make
      sure they have setup everything correctly.

      Elastic scaling: use an assumed `CoreIndex` in `candidate-backing` (#3229) · 60e537b9
      Andrei Sandu authored
      
      
      First step in implementing
      https://github.com/paritytech/polkadot-sdk/issues/3144
      
      ### Summary of changes
      - switch statement `Table` candidate mapping from `ParaId` to
      `CoreIndex`
      - introduce experimental `InjectCoreIndex`  node feature.
      - determine and assume a `CoreIndex` for a candidate based on statement
      validator index. If the signature is valid it means validator controls
      the validator that index and we can easily map it to a validator
      group/core.
      - introduce a temporary provisioner fix until we fully enable elastic
      scaling in the subystem. The fix ensures we don't fetch the same
      backable candidate when calling `get_backable_candidate` for each core.
      
      TODO:
      - [x] fix backing tests
      - [x] fix statement table tests

      Contracts: xcm host fn fixes (#3086) · ca382f32
      PG Herveou authored
      ## Xcm changes:
      - Fix `pallet_xcm::execute`, move the logic into The `ExecuteController`
      so it can be shared with anything that implement that trait.
      - Make `ExecuteController::execute` retursn `DispatchErrorWithPostInfo`
      instead of `DispatchError`, so that we don't charge the full
      `max_weight` provided if the execution is incomplete (useful for
      force_batch or contracts calls)
      - Fix docstring for `pallet_xcm::execute`, to reflect the changes from
      #2405
      - Update the signature for `ExecuteController::execute`, we don't need
      to return the `Outcome` anymore since we only care about
      `Outcome::Complete`
      
      ## Contracts changes:
      
      - Update host fn `xcm_exexute`, we don't need to write the `Outcome` to
      the sandbox memory anymore. This was also not charged as well before so
      it if fixes this too.
      - One of the issue was that the dry_run of a contract that call
      `xcm_execute` would exhaust the `gas_limit`.
      
      This is because `XcmExecuteController::execute` takes a `max_weight`
      argument, and since we don't want the user to specify it manually we
      were passing everything left by pre-charghing
      `ctx.ext.gas_meter().gas_left()`
      
      - To fix it I added a `fn influence_lowest_limit` on the `Token` trait
      and make it return false for `RuntimeCost::XcmExecute`.
      - Got rid of the `RuntimeToken` indirection, we can just use
      `RuntimeCost` directly.

      gossip-support: add unittests for update authorities (#3258) · 197c6cf9
      Alexandru Gheorghe authored
      
      
      ~The previous fix was actually incomplete because we update the
      authorties only on the situation where we decided to reconnect because
      we had a low connectivity issue. Now the problem is that
      update_authority_ids use the list of connected peers, so on restart that
      does contain anything, so calling immediately after
      issue_connection_request won't detect all authorities, so we need to
      also check every block as the comment said, but that did not match the
      code.~
      
      Actually the fix was correct the flow is follow if more than 1/3 of the
      authorities can not be resolved we set last_failure and call
      `ConnectToResolvedValidators`.
      
      We will call UpdateAuthorities for all the authorities already connected
      and for which we already know the address and for the ones that will
      connect later on `PeerConnected` will have the AuthorityId field set,
      because it is already known, so approval-distribution will update its
      cache topology.

      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.

      Implements a % cap on staking rewards from era inflation (#1660) · fde44474
      Gonçalo Pestana authored
      This PR implements an (optional) cap of the era inflation that is
      allocated to staking rewards. The remaining is minted directly into the
      [`RewardRemainder`](https://github.com/paritytech/polkadot-sdk/blob/fb0fd3e6/substrate/frame/staking/src/pallet/mod.rs#L160)
      account, which is the treasury pot account in Polkadot and Kusama.
      
      The staking pallet now has a percent storage item, `MaxStakersRewards`,
      which defines the max percentage of the era inflation that should be
      allocated to staking rewards. The remaining era inflation (i.e.
      `remaining = max_era_payout - staking_payout.min(staking_payout *
      MaxStakersRewards))` is minted directly into the treasury.
      
      The `MaxStakersRewards` can be set by a privileged origin through the
      `set_staking_configs` extrinsic.
