      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.

      Prepare syncing for parallel sync strategies (#3224) · 96ebb305
      Dmitry Markin authored
      This PR should supersede
      https://github.com/paritytech/polkadot-sdk/pull/2814 and accomplish the
      same with less changes. It's needed to run sync strategies in parallel,
      like running `ChainSync` and `GapSync` as independent strategies, and
      running `ChainSync` and Sync 2.0 alongside each other.
      
      The difference with https://github.com/paritytech/polkadot-sdk/pull/2814
      is that we allow simultaneous requests to remote peers initiated by
      different strategies, as this is not tracked on the remote node in any
      way. Therefore, `PeerPool` is not needed.

      Use `TEST_WS` in all remote-externalities tests (#3284) · b2a62a56
      Bruno Galvao authored
      
      
      Refactor in accordance with
      https://github.com/paritytech/polkadot-sdk/issues/2245#issuecomment-1937025951
      
      Prior to this PR, the `remote_tests` test module would either use
      `TEST_WS` or `DEFAULT_HTTP_ENDPOINT`.
      
      With the PR, `TEST_WS` is the default for the `remote_tests` test module
      and the fallback is `DEFAULT_HTTP_ENDPOINT`.
      
      The only downside I see to this PR is that for particular tests in the
      `remote_tests` module, one would want to use a different http endpoint.
      If that is the case, they would have to manually hardcode the http
      endpoint for that particular test.
      
      Note: The `TEST_WS` node should fulfill the role for all test cases e.g.
      include child tries.
      
      Give it a _try_:
      ```
      TEST_WS=wss://rococo-try-runtime-node.parity-chains.parity.io:443 cargo test --features=remote-test -p frame-remote-externalities -- --nocapture
      ```

      This error suggests using either `unvote` or `reap_vote` calls which are

      rpc-v2/tx: Implement `transaction_unstable_broadcast` and `transaction_unstable_stop` (#3079) · bde0bbe5
      Alexandru Vasile authored
      
      
      This PR implements the
      [transaction_unstable_broadcast](https://github.com/paritytech/json-rpc-interface-spec/blob/main/src/api/transaction_unstable_broadcast.md)
      and
      [transaction_unstable_stop](https://github.com/paritytech/json-rpc-interface-spec/blob/main/src/api/transaction_unstable_stop.md).
      
      
      The
      [transaction_unstable_broadcast](https://github.com/paritytech/json-rpc-interface-spec/blob/main/src/api/transaction_unstable_broadcast.md)
      submits the provided transaction at the best block of the chain.
      If the transaction is dropped or declared invalid, the API tries to
      resubmit the transaction at the next available best block.
      
      ### Broadcasting 
      The broadcasting operation continues until either:
      
      - the user called `transaction_unstable_stop` with the operation ID that
      identifies the broadcasting operation
      - the transaction state is one of the following: 
        - Finalized: the transaction is part of the chain
      - FinalizedTimeout: we have waited for 256 finalized blocks and timedout
        - Usurped the transaction has been replaced in the tx pool
        
      The broadcasting retires to submit the transaction when the transaction
      state is:
      - Invalid: the transaction might become valid at a later time
      - Dropped: the transaction pool's capacity is full at the moment, but
      might clear when other transactions are finalized/dropped
      
      ### Stopping
      
      The `transaction_unstable_broadcast` spawns an abortable future and
      tracks the abort handler.
      When the
      [transaction_unstable_stop](https://github.com/paritytech/json-rpc-interface-spec/blob/main/src/api/transaction_unstable_stop.md)
      is called with a valid operation ID; the abort handler of the
      corresponding `transaction_unstable_broadcast` future is called. This
      behavior ensures the broadcast future is finishes on the next polling.
      When the `transaction_unstable_stop` is called with an invalid operation
      ID, an invalid jsonrpc specific error object is returned.
      
      
      ### Testing
      
      This PR adds the testing harness of the transaction API and validates
      two basic scenarios:
      - transaction enters and exits the transaction pool
      - transaction stop returns appropriate values when called with valid and
      invalid operation IDs
      
      
      Closes: https://github.com/paritytech/polkadot-sdk/issues/3039
      
      Note that the API should be enabled after:

      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.

      transaction-pool: Improve transaction status documentation and add helpers (#3215) · 4f13d5b7
      Alexandru Vasile authored
      
      
      This PR improves the transaction status documentation.
      - Added doc references for describing the main states
      - Extra comment wrt pool ready / future queues
      - `FinalityTimeout` no longer describes a lagging finality gadget, it
      signals that the maximum number of finality gadgets has been reached
      
      A few helper methods are added to indicate when:
      - a final event is generated by the transaction pool for a given event
      - a final event is provided, although the transaction might become valid
      at a later time and could be re-submitted
      
      The helper methods are used and taken from
      https://github.com/paritytech/polkadot-sdk/pull/3079 to help us better
      keep it in sync.

      [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;

      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, ()> {

      Fixes `TotalValueLocked` out of sync in nomination pools (#3052) · aac07af0
      Gonçalo Pestana authored
      The `TotalLockedValue` storage value in nomination pools pallet may get
      out of sync if the staking pallet does implicit withdrawal of unlocking
      chunks belonging to a bonded pool stash. This fix is based on a new
      method in the `OnStakingUpdate` traits, `on_withdraw`, which allows the
      nomination pools pallet to adjust the `TotalLockedValue` every time
      there is an implicit or explicit withdrawal from a bonded pool's stash.
      
      This PR also adds a migration that checks and updates the on-chain TVL
      if it got out of sync due to the bug this PR fixes.
      
      **Changes to `trait OnStakingUpdate`**
      
      In order for staking to notify the nomination pools pallet that chunks
      where withdrew, we add a new method, `on_withdraw` to the
      `OnStakingUpdate` trait. The nomination pools pallet filters the
      withdraws that are related to bonded pool accounts and updates the
      `TotalValueLocked` accordingly.
      
      **Others**
      - Adds try-state checks to the EPM/staking e2e tests
      - Adds tests for auto withdrawing in the context of nomination pools
      
      **To-do**
      - [x] check if we need a migration to fix the current `TotalValueLocked`
      (run try-runtime)
      - [x] migrations to fix the current on-chain TVL value 
      
        **Kusama**:
      ```
      TotalValueLocked: 99.4559 kKSM
      TotalValueLocked (calculated) 99.4559 kKSM
      ```
      
      
      ️ **Westend**:
      ```
      TotalValueLocked: 18.4060 kWND
      TotalValueLocked (calculated) 18.4050 kWND
      ```
      **Polkadot**: TVL not released yet.

      Make BEEFY client keystore generic over BEEFY `AuthorityId` type (#2258) · 0a94124d
      drskalman authored
      
      
      This is the significant step to make BEEFY client able to handle both
      ECDSA and (ECDSA, BLS) type signature. The idea is having BEEFY Client
      generic on crypto types makes migration to new types smoother.
      
      This makes the BEEFY Keystore generic over AuthorityId and extends its
      tests to cover the case when the AuthorityId is of type (ECDSA,
      BLS12-377)

      contracts: Remove no longer enforced limits from the `Schedule` (#3184) · d54412ce
      Alexander Theißen authored
      When switching from the instrumented gas metering to the wasmi gas
      metering we also removed all imposed limits regarding Wasm module
      internals. All those things do not interact with the host and have to be
      handled by wasmi. For example, Wasmi charges additional gas for
      parameters to each function because as they incur some overhead.
      
      Back then we took the opportunity to remove the dependency on the
      deprecated `parity-wasm` which was used to enforce those limits.
      
      This PR merely removes them from the `Schedule` they aren't enforced for
      a while.

      contracts: Don't fail fast if the `Weight` limit of a cross contract call is too big (#3243) · 28463a12
      Alexander Theißen authored
      
      
      When doing a cross contract call you can supply an optional Weight limit
      for that call. If one doesn't specify the limit (setting it to 0) the
      sub call will have all the remaining gas available. If one does specify
      the limit we subtract that amount eagerly from the Weight meter and fail
      fast if not enough `Weight` is available.
      
      This is quite annoying because setting a fixed limit will set the
      `gas_required` in the gas estimation according to the specified limit.
      Even if in that dry-run the actual call didn't consume that whole
      amount. It effectively discards the more precise measurement it should
      have from the dry-run.
      
      This PR changes the behaviour so that the supplied limit is an actual
      limit: We do the cross contract call even if the limit is higher than
      the remaining `Weight`. We then fail and roll back in the cub call in
      case there is not enough weight.
      
      This makes the weight estimation in the dry-run no longer dependent on
      the weight limit supplied when doing a cross contract call.

      [pallet_broker] Remove leases that have already expired in rotate_sale (#3213) · 2ea6bcf1
      Dónal Murray authored
      Leases can be force set, but since `Leases` is a `StorageValue`, if a
      lease misses its sale rotation in which it should expire, it can never
      be cleared.
      
      This can happen if a lease is added with an `until` timeslice that lies
      in a region whose sale has already started or has passed, even if the
      timeslice itself hasn't passed.
      
      This solves that issue in a minimal way, with all expired leases being
      cleaned up in each sale rotation, not just the ones that are expiring in
      the coming region.

      Build more runtimes targeting PolkaVM (#3209) · 402b64ca
      Koute authored
      This PR improves compatibility with RISC-V and PolkaVM, allowing more
      runtimes to successfully compile.
      
      In particular, it makes the following changes:
      
      - The `sp-mmr-primitives` and `sp-consensus-beefy` crates
      unconditionally required an `std`-only dependency; now they only require
      those dependencies when the `std` feature is actually enabled. (Our
      RISC-V target is, unlike WASM, a true `no_std` target where you can't
      accidentally use stuff from `std` anymore.)
      - One of our dependencies (the `bitvec` trace) uses a crate called
      `radium` which doesn't compile under RISC-V due to incomplete
      autodetection logic in their `build.rs` file. The good news is that this
      is already fixed in the newest upstream version of `radium`, and the
      newest version of `bitvec` uses it. The bad news is that the newest
      version of `bitvec` is not currently released on crates.io, so we can't
      use it. I've [created an
      issue](https://github.com/ferrilab/ferrilab/issues/5) asking for a new
      release, but in the meantime I forked the currently used `radium` 0.7,
      [fixed the faulty
      logic](https://github.com/paritytech/radium-0.7-fork/commit/ed66c8a294b138c67f93499644051d97d4c7fbda)
      and used cargo's patching capabilities to use it for the RISC-V runtime
      builds. This might be a little hacky, but it is the least intrusive way
      to fix the problem, doesn't affect WASM builds at all, and we can
      trivially remove it once a new `bitvec` is released.
      - The new runtimes are added to the CI to make sure their compilation
      doesn't break.

      This is just looking at /substrate and moving some of the references
      from `sp-std` to `core`.
      These particular changes should be uncontroversial.
      
      Where macros are used `::core` should be used to remove any ambiguity.

      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;
      ```

      Initial support for building RISC-V runtimes targeting PolkaVM (#3179) · e349fc9e
      Koute authored
      This PR adds initial support for building RISC-V runtimes targeting
      PolkaVM.
      
      - Setting the `SUBSTRATE_RUNTIME_TARGET=riscv` environment variable will
      now build a RISC-V runtime instead of a WASM runtime.
      - This only adds support for *building* runtimes; running them will need
      a PolkaVM-based executor, which I will add in a future PR.
      - Only building the minimal runtime is supported (building the Polkadot
      runtime doesn't work *yet* due to one of the dependencies).
      - The builder now sets a `substrate_runtime` cfg flag when building the
      runtimes, with the idea being that instead of doing `#[cfg(not(feature =
      "std"))]` or `#[cfg(target_arch = "wasm32")]` to detect that we're
      building a runtime you'll do `#[cfg(substrate_runtime)]`. (Switching the
      whole codebase to use this will be done in a future PR; I deliberately
      didn't do this here to keep this PR minimal and reviewable.)
      - Further renaming of things (e.g. types, environment variables and proc
      macro attributes having "wasm" in their name) to be target-agnostic will
      also be done in a future refactoring PR (while keeping backwards
      compatibility where it makes sense; I don't intend to break anyone's
      workflow or create unnecessary churn).
      - This PR also fixes two bugs in the `wasm-builder` crate:
      * The `RUSTC` environment variable is now removed when invoking the
      compiler. This prevents the toolchain version from being overridden when
      called from a `build.rs` script.
      * When parsing the `rustup toolchain list` output the `(default)` is now
      properly stripped and not treated as part of the version.
      - I've also added a minimal CI job that makes sure this doesn't break in
      the future. (cc @paritytech/ci)
      
      cc @athei
      
      
      
      ------
      
      Also, just a fun little tidbit: quickly comparing the size of the built
      runtimes it seems that the PolkaVM runtime is slightly smaller than the
      WASM one. (`production` build, with the `names` section substracted from
      the WASM's size to keep things fair, since for the PolkaVM runtime we're
      currently stripping out everything)
      
      - `.wasm`: 625505 bytes
      - `.wasm` (after wasm-opt -O3): 563205 bytes
      - `.wasm` (after wasm-opt -Os): 562987 bytes
      - `.wasm` (after wasm-opt -Oz): 536852 bytes
      - `.polkavm`: ~~580338 bytes~~ 550476 bytes (after enabling extra target
      features; I'll add those in another PR once we have an executor working)

      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

      /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`.
