      approval-voting improvement: include all tranche0 assignments in one certificate (#1178) · 0570b6fa
      Andrei Sandu authored
      
      
      **_PR migrated from https://github.com/paritytech/polkadot/pull/6782_** 
      
      This PR will upgrade the network protocol to version 3 -> VStaging which
      will later be renamed to V3. This version introduces a new kind of
      assignment certificate that will be used for tranche0 assignments.
      Instead of issuing/importing one tranche0 assignment per candidate,
      there will be just one certificate per relay chain block per validator.
      However, we will not be sending out the new assignment certificates,
      yet. So everything should work exactly as before. Once the majority of
      the validators have been upgraded to the new protocol version we will
      enable the new certificates (starting at a specific relay chain block)
      with a new client update.
      
      There are still a few things that need to be done:
      
      - [x] Use bitfield instead of Vec<CandidateIndex>:
      https://github.com/paritytech/polkadot/pull/6802
        - [x] Fix existing approval-distribution and approval-voting tests

      runtime `GenesisBuilder` API.
      - interacting with arbitrary runtime wasm blob to[

      but also changes the signature of this method extending it with `code`
      argument.
      [`ChainSpec::builder()`](https://github.com/paritytech/substrate/blob/20bee680ed098be7239cf7a6b804cd4de267983e/client/chain-spec/src/chain_spec.rs#L507)
      should be used instead.
      - `polkadot`:
      - all references to `RuntimeGenesisConfig` in `node/service` are
      removed,
      - all
      `(kusama|polkadot|versi|rococo|wococo)_(staging|dev)_genesis_config`
      functions now return the JSON patch for default runtime `GenesisConfig`,
        - `ChainSpecBuilder` is used, `ChainSpec::from_genesis` is removed,
      
      - `cumulus`:
        - `ChainSpecBuilder` is used, `ChainSpec::from_genesis` is removed,
      - _JSON_ patch configuration used instead of `RuntimeGenesisConfig
      struct` in all chain specs.

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

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

      Use `Message Queue` as DMP and XCMP dispatch queue (#1246) · e1c033eb
      Oliver Tale-Yazdi authored
      
      
      (imported from https://github.com/paritytech/cumulus/pull/2157)
      
      ## Changes
      
      This MR refactores the XCMP, Parachains System and DMP pallets to use
      the [MessageQueue](https://github.com/paritytech/substrate/pull/12485)
      for delayed execution of incoming messages. The DMP pallet is entirely
      replaced by the MQ and thereby removed. This allows for PoV-bounded
      execution and resolves a number of issues that stem from the current
      work-around.
      
      All System Parachains adopt this change.  
      The most important changes are in `primitives/core/src/lib.rs`,
      `parachains/common/src/process_xcm_message.rs`,
      `pallets/parachain-system/src/lib.rs`, `pallets/xcmp-queue/src/lib.rs`
      and the runtime configs.
      
      ### DMP Queue Pallet
      
      The pallet got removed and its logic refactored into parachain-system.
      Overweight message management can be done directly through the MQ
      pallet.
      
      Final undeployment migrations are provided by
      `cumulus_pallet_dmp_queue::UndeployDmpQueue` and `DeleteDmpQueue` that
      can be configured with an aux config trait like:
      
      ```rust
      parameter_types! {
      	pub const DmpQueuePalletName: &'static str = \"DmpQueue\" < CHANGE ME;
      	pub const RelayOrigin: AggregateMessageOrigin = AggregateMessageOrigin::Parent;
      }
      
      impl cumulus_pallet_dmp_queue::MigrationConfig for Runtime {
      	type PalletName = DmpQueuePalletName;
      	type DmpHandler = frame_support::traits::EnqueueWithOrigin<MessageQueue, RelayOrigin>;
      	type DbWeight = <Runtime as frame_system::Config>::DbWeight;
      }
      
      // And adding them to your Migrations tuple:
      pub type Migrations = (
      	...
      	cumulus_pallet_dmp_queue::UndeployDmpQueue<Runtime>,
      	cumulus_pallet_dmp_queue::DeleteDmpQueue<Runtime>,
      );
      ```
      
      ### XCMP Queue pallet
      
      Removed all dispatch queue functionality. Incoming XCMP messages are now
      either: Immediately handled if they are Signals, enqueued into the MQ
      pallet otherwise.
      
      New config items for the XCMP queue pallet:
      ```rust
      /// The actual queue implementation that retains the messages for later processing.
      type XcmpQueue: EnqueueMessage<ParaId>;
      
      /// How a XCM over HRMP from a sibling parachain should be processed.
      type XcmpProcessor: ProcessMessage<Origin = ParaId>;
      
      /// The maximal number of suspended XCMP channels at the same time.
      #[pallet::constant]
      type MaxInboundSuspended: Get<u32>;
      ```
      
      How to configure those:
      
      ```rust
      // Use the MessageQueue pallet to store messages for later processing. The `TransformOrigin` is needed since
      // the MQ pallet itself operators on `AggregateMessageOrigin` but we want to enqueue `ParaId`s.
      type XcmpQueue = TransformOrigin<MessageQueue, AggregateMessageOrigin, ParaId, ParaIdToSibling>;
      
      // Process XCMP messages from siblings. This is type-safe to only accept `ParaId`s. They will be dispatched
      // with origin `Junction::Sibling(…)`.
      type XcmpProcessor = ProcessFromSibling<
      	ProcessXcmMessage<
      		AggregateMessageOrigin,
      		xcm_executor::XcmExecutor<xcm_config::XcmConfig>,
      		RuntimeCall,
      	>,
      >;
      
      // Not really important what to choose here. Just something larger than the maximal number of channels.
      type MaxInboundSuspended = sp_core::ConstU32<1_000>;
      ```
      
      The `InboundXcmpStatus` storage item was replaced by
      `InboundXcmpSuspended` since it now only tracks inbound queue suspension
      and no message indices anymore.
      
      Now only sends the most recent channel `Signals`, as all prio ones are
      out-dated anyway.
      
      ### Parachain System pallet
      
      For `DMP` messages instead of forwarding them to the `DMP` pallet, it
      now pushes them to the configured `DmpQueue`. The message processing
      which was triggered in `set_validation_data` is now being done by the MQ
      pallet `on_initialize`.
      
      XCMP messages are still handed off to the `XcmpMessageHandler`
      (XCMP-Queue pallet) - no change here.
      
      New config items for the parachain system pallet:
      ```rust
      /// Queues inbound downward messages for delayed processing. 
      ///
      /// Analogous to the `XcmpQueue` of the XCMP queue pallet.
      type DmpQueue: EnqueueMessage<AggregateMessageOrigin>;
      ``` 
      
      How to configure:
      ```rust
      /// Use the MQ pallet to store DMP messages for delayed processing.
      type DmpQueue = MessageQueue;
      ``` 
      
      ## Message Flow
      
      The flow of messages on the parachain side. Messages come in from the
      left via the `Validation Data` and finally end up at the `Xcm Executor`
      on the right.

      ## Further changes
      
      - Bumped the default suspension, drop and resume thresholds in
      `QueueConfigData::default()`.
      - `XcmpQueue::{suspend_xcm_execution, resume_xcm_execution}` errors when
      they would be a noop.
      - Properly validate the `QueueConfigData` before setting it.
      - Marked weight files as auto-generated so they wont auto-expand in the
      MR files view.
      - Move the `hypothetical` asserts to `frame_support` under the name
      `experimental_hypothetically`
      
      Questions:
      - [ ] What about the ugly `#[cfg(feature = \"runtime-benchmarks\")]` in
      the runtimes? Not sure how to best fix. Just having them like this makes
      tests fail that rely on the real message processor when the feature is
      enabled.
      - [ ] Need a good weight for `MessageQueueServiceWeight`. The scheduler
      already takes 80% so I put it to 10% but that is quite low.
      
      TODO:
      - [x] Remove c&p code after
      https://github.com/paritytech/polkadot/pull/6271
      - [x] Use `HandleMessage` once it is public in Substrate
      - [x] fix `runtime-benchmarks` feature

      - [x] Possibly cleanup Migrations (DMP+XCMP)
      - [x] optional: create `TransformProcessMessageOrigin` in Substrate and
      replace `ProcessFromSibling`
      - [ ] Rerun weights on ref HW

      [NPoS] Paging reward payouts in order to scale rewardable nominators (#1189) · 00b85c51
      Ankan authored
      
      
      helps https://github.com/paritytech/polkadot-sdk/issues/439.
      closes https://github.com/paritytech/polkadot-sdk/issues/473.
      
      PR link in the older substrate repository:
      https://github.com/paritytech/substrate/pull/13498.
      
      # Context
      Rewards payout is processed today in a single block and limited to
      `MaxNominatorRewardedPerValidator`. This number is currently 512 on both
      Kusama and Polkadot.
      
      This PR tries to scale the nominators payout to an unlimited count in a
      multi-block fashion. Exposures are stored in pages, with each page
      capped to a certain number (`MaxExposurePageSize`). Starting out, this
      number would be the same as `MaxNominatorRewardedPerValidator`, but
      eventually, this number can be lowered through new runtime upgrades to
      limit the rewardeable nominators per dispatched call instruction.
      
      The changes in the PR are backward compatible.
      
      ## How payouts would work like after this change
      Staking exposes two calls, 1) the existing `payout_stakers` and 2)
      `payout_stakers_by_page`.
      
      ### payout_stakers
      This remains backward compatible with no signature change. If for a
      given era a validator has multiple pages, they can call `payout_stakers`
      multiple times. The pages are executed in an ascending sequence and the
      runtime takes care of preventing double claims.
      
      ### payout_stakers_by_page
      Very similar to `payout_stakers` but also accepts an extra param
      `page_index`. An account can choose to payout rewards only for an
      explicitly passed `page_index`.
      
      **Lets look at an example scenario**
      Given an active validator on Kusama had 1100 nominators,
      `MaxExposurePageSize` set to 512 for Era e. In order to pay out rewards
      to all nominators, the caller would need to call `payout_stakers` 3
      times.
      
      - `payout_stakers(origin, stash, e)` => will pay the first 512
      nominators.
      - `payout_stakers(origin, stash, e)` => will pay the second set of 512
      nominators.
      - `payout_stakers(origin, stash, e)` => will pay the last set of 76
      nominators.
      ...
      - `payout_stakers(origin, stash, e)` => calling it the 4th time would
      return an error `InvalidPage`.
      
      The above calls can also be replaced by `payout_stakers_by_page` and
      passing a `page_index` explicitly.
      
      ## Commission note
      Validator commission is paid out in chunks across all the pages where
      each commission chunk is proportional to the total stake of the current
      page. This implies higher the total stake of a page, higher will be the
      commission. If all the pages of a validator's single era are paid out,
      the sum of commission paid to the validator across all pages should be
      equal to what the commission would have been if we had a non-paged
      exposure.
      
      ### Migration Note
      Strictly speaking, we did not need to bump our storage version since
      there is no migration of storage in this PR. But it is still useful to
      mark a storage upgrade for the following reasons:
      
      - New storage items are introduced in this PR while some older storage
      items are deprecated.
      - For the next `HistoryDepth` eras, the exposure would be incrementally
      migrated to its corresponding paged storage item.
      - Runtimes using staking pallet would strictly need to wait at least
      `HistoryDepth` eras with current upgraded version (14) for the migration
      to complete. At some era `E` such that `E >
      era_at_which_V14_gets_into_effect + HistoryDepth`, we will upgrade to
      version X which will remove the deprecated storage items.
      In other words, it is a strict requirement that E<sub>x</sub> -
      E<sub>14</sub> > `HistoryDepth`, where
      E<sub>x</sub> = Era at which deprecated storages are removed from
      runtime,
      E<sub>14</sub> = Era at which runtime is upgraded to version 14.
      - For Polkadot and Kusama, there is a [tracker
      ticket](https://github.com/paritytech/polkadot-sdk/issues/433) to clean
      up the deprecated storage items.
      
      ### Storage Changes
      
      #### Added
      - ErasStakersOverview
      - ClaimedRewards
      - ErasStakersPaged
      
      #### Deprecated
      The following can be cleaned up after 84 eras which is tracked
      [here](https://github.com/paritytech/polkadot-sdk/issues/433).
      
      - ErasStakers.
      - ErasStakersClipped.
      - StakingLedger.claimed_rewards, renamed to
      StakingLedger.legacy_claimed_rewards.
      
      ### Config Changes
      - Renamed MaxNominatorRewardedPerValidator to MaxExposurePageSize.
      
      ### TODO
      - [x] Tracker ticket for cleaning up the old code after 84 eras.

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

      We shouldn't override with their default fields that have been added in
      the previous version(v8), because we are going to lose whatever values have
      been set.
      
      Note, v8 & v9 seems to have landed at the same time on Rococo, probably
      they will land at the same time on westend and other chains, so functionally
      doesn't make much difference, but let's have this fixed for people that copy-paste
      :D, like me.

      Closes https://github.com/paritytech/release-engineering/issues/6
      
      Adds a new Github Workflow which on a new release being created, builds
      and attaches all runtimes managed in this repository in two flavours:
      - `dev-debug-build`: Built with the `try-runtime` feature and has
      logging enabled
      - `on-chain-release`: Built with the regular old `on-chain-release`
      feature
      
      The new Github Workflow could be extended in the future by the
      @paritytech/release-engineering team to fully automate the release
      process if they choose to, similar to how it is fully automated in the
      Fellowship repo
      (https://github.com/polkadot-fellows/runtimes/blob/main/.github/workflows/release.yml).
      
      The `on-chain-release` did not exist for parachains, so I added it.

      While investigating some db migrations that make the node startup fail,
      I noticed that the node wasn't exiting and that the log file were
      growing exponentially, until my whole system was freezing and that makes
      it really hard to actually find why it was failing in the first place.
      
      E.g:
      ```
       ls -lh /tmp/zombie-01a04c2a2c0265d85f6440cf01c0f44a_-51319-uyggzuD4wEpV/bob.log

      ```
      
      This was happening because the following errors were being printed
      continously without the subsystem main loop exiting:
      
      From dispute-coordinator:
      ```
      WARN tokio-runtime-worker parachain::dispute-coordinator: error=Subsystem(Generated(Context("Signal channel is terminated and empty.")))
      ```
      
      From availability recovery:
      ```
      Erasure task channel closed. Node shutting down ?

      `polkadot-parachain-primitives` should not depend on `frame-support`. (#1897) · bdf18687
      Joshy Orndorff authored
      
      
      This PR does not make any functional changes to the code. Rather, it
      restructures the dependency graph.
      
      Before this PR, the crate `polkadot-parachain-primitives` depended
      directly on the crate `frame-support`. This is wrong in principal
      because a parachain does not necessarily have anything to do with frame.
      
      This dependency was only for the `Weight` type which was just a
      re-export from `sp-weights` anyway. So this PR changes the dependency to
      be directly on the much lighter `sp-weights`.
