      Adds syntax for marking calls feeless (#1926) · 60c77a2e
      gupnik authored
      
      
      Fixes https://github.com/paritytech/polkadot-sdk/issues/1725
      
      This PR adds the following changes:
      1. An attribute `pallet::feeless_if` that can be optionally attached to
      a call like so:
      ```rust
      #[pallet::feeless_if(|_origin: &OriginFor<T>, something: &u32| -> bool {
      	*something == 0
      })]
      pub fn do_something(origin: OriginFor<T>, something: u32) -> DispatchResult {
           ....
      }
      ```
      The closure passed accepts references to arguments as specified in the
      call fn. It returns a boolean that denotes the conditions required for
      this call to be "feeless".
      
      2. A signed extension `SkipCheckIfFeeless<T: SignedExtension>` that
      wraps a transaction payment processor such as
      `pallet_transaction_payment::ChargeTransactionPayment`. It checks for
      all calls annotated with `pallet::feeless_if` to see if the conditions
      are met. If so, the wrapped signed extension is not called, essentially
      making the call feeless.
      
      In order to use this, you can simply replace your existing signed
      extension that manages transaction payment like so:
      ```diff
      - pallet_transaction_payment::ChargeTransactionPayment<Runtime>,
      + pallet_skip_feeless_payment::SkipCheckIfFeeless<
      +	Runtime,
      +	pallet_transaction_payment::ChargeTransactionPayment<Runtime>,
      + >,
      ```

      pallet-grandpa: Remove `GRANDPA_AUTHORITIES_KEY` (#2181) · ebcf0a0f
      Bastian Köcher authored
      
      
      Remove the `GRANDPA_AUTHORITIES_KEY` key and its usage. Apparently this
      was used in the early days to communicate the grandpa authorities to the
      node. However, we have now a runtime api that does this for us. So, this
      pull request is moving from the custom managed storage item to a FRAME
      managed storage item.
      
      This pr also includes a migration for doing the switch on a running
      chain.

      sc-state-db: Keep track of `LAST_PRUNED` after warp syncing (#2228) · b0d0fb31
      Bastian Köcher authored
      When warp syncing we import the target block with all its state.
      However, we didn't store the `LAST_PRUNED` block which would then lead
      to `pruning` to forget about the imported block after a restart of the
      node. We just set `LAST_PRUNED` to the parent block of the warp sync
      target block to fix this issue.

      Initialise on-chain `StorageVersion` for pallets added after genesis (#1297) · c4211b65
      Liam Aharon authored
      
      
      Original PR https://github.com/paritytech/substrate/pull/14641
      
      ---
      
      Closes https://github.com/paritytech/polkadot-sdk/issues/109
      
      ### Problem
      Quoting from the above issue:
      
      > When adding a pallet to chain after genesis we currently don't set the
      StorageVersion. So, when calling on_chain_storage_version it returns 0
      while the pallet is maybe already at storage version 9 when it was added
      to the chain. This could lead to issues when running migrations.
      
      ### Solution
      
      - Create a new trait `BeforeAllRuntimeMigrations` with a single method
      `fn before_all_runtime_migrations() -> Weight` trait with a noop default
      implementation
      - Modify `Executive` to call
      `BeforeAllRuntimeMigrations::before_all_runtime_migrations` for all
      pallets before running any other hooks
      - Implement `BeforeAllRuntimeMigrations` in the pallet proc macro to
      initialize the on-chain version to the current pallet version if the
      pallet has no storage set (indicating it has been recently added to the
      runtime and needs to have its version initialised).
      
      ### Other changes in this PR
      
      - Abstracted repeated boilerplate to access the `pallet_name` in the
      pallet expand proc macro.
      
      ### FAQ
      
      #### Why create a new hook instead of adding this logic to the pallet
      `pre_upgrade`?
      
      `Executive` currently runs `COnRuntimeUpgrade` (custom migrations)
      before `AllPalletsWithSystem` migrations. We need versions to be
      initialized before the `COnRuntimeUpgrade` migrations are run, because
      `COnRuntimeUpgrade` migrations may use the on-chain version for critical
      logic. e.g. `VersionedRuntimeUpgrade` uses it to decide whether or not
      to execute.
      
      We cannot reorder `COnRuntimeUpgrade` and `AllPalletsWithSystem` so
      `AllPalletsWithSystem` runs first, because `AllPalletsWithSystem` have
      some logic in their `post_upgrade` hooks to verify that the on-chain
      version and current pallet version match. A common use case of
      `COnRuntimeUpgrade` migrations is to perform a migration which will
      result in the versions matching, so if they were reordered these
      `post_upgrade` checks would fail.
      
      #### Why init the on-chain version for pallets without a current storage
      version?
      
      We must init the on-chain version for pallets even if they don't have a
      defined storage version so if there is a future version bump, the
      on-chain version is not automatically set to that new version without a
      proper migration.
      
      e.g. bad scenario:
      
      1. A pallet with no 'current version' is added to the runtime
      2. Later, the pallet is upgraded with the 'current version' getting set
      to 1 and a migration is added to Executive Migrations to migrate the
      storage from 0 to 1
          a. Runtime upgrade occurs
          b. `before_all` hook initializes the on-chain version to 1
      c. `on_runtime_upgrade` of the migration executes, and sees the on-chain
      version is already 1 therefore think storage is already migrated and
      does not execute the storage migration
      Now, on-chain version is 1 but storage is still at version 0.
      
      By always initializing the on-chain version when the pallet is added to
      the runtime we avoid that scenario.

      TryDecodeEntireState check for storage types and pallets (#1805) · 32a97408
      Piet authored
      ### This PR is a port of this [PR for
      substrate](https://github.com/paritytech/substrate/pull/13013) by
      @Kianenigma
      
      
      
      Add infrastructure needed to have a Pallet::decode_entire_state(), which
      makes sure all "typed" storage items defined in the pallet are
      decode-able.
      
      This is not enforced in any way at the moment. Teams who wish to
      integrate/use this in the try-runtime feature flag should add
      frame_support::storage::migration::EnsureStateDecodes as the LAST ITEM
      of the runtime's custom migrations, and pass it to frame-executive. This
      will make it usable in try-runtime on-runtime-upgrade.
      
      This now catches cases like
      https://github.com/paritytech/polkadot-sdk/pull/1969:
      ```pre
      ERROR runtime::executive] failed to decode the value at key: Failed to decode value at key: 0x94eadf0156a8ad5156507773d0471e4ab8ebad86f546c7e0b135a4212aace339.

Raw value: Some("0x0c010101010101")
      ```

      runtime `GenesisBuilder` API.
      - interacting with arbitrary runtime wasm blob to[
      `chain-spec-builder`](https://github.com/paritytech/substrate/blob/3ef576eaeb3f42610e85daecc464961cf1295570/bin/utils/chain-spec-builder/src/lib.rs#L46)
      command line util,
      - removes
      [`code`](https://github.com/paritytech/substrate/blob/3ef576eaeb3f42610e85daecc464961cf1295570/frame/system/src/lib.rs#L660)
      from `system_pallet`
        - adds `code` to the `ChainSpec`
      - deprecates
      [`ChainSpec::from_genesis`](https://github.com/paritytech/substrate/blob/3ef576eaeb3f42610e85daecc464961cf1295570/client/chain-spec/src/chain_spec.rs#L263),
      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.

      > ensure through proper configuration that the new byte-based deposit is

      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");
      ```

      The check_hardware functions does not give us too much information as to

      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.

      (1)](https://github.com/paritytech/cumulus/assets/10380170/6cf8b377-88c9-4aed-96df-baace266e04d)
      
      ## 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] Possibly cleanup Migrations (DMP+XCMP)
      - [x] optional: create `TransformProcessMessageOrigin` in Substrate and
      replace `ProcessFromSibling`
      - [ ] Rerun weights on ref HW

      Make `ExecResult` encodable (#1809) · 10857d0b
      Piotr Mikołajczyk authored
      # Description
      We derive few useful traits on `ErrorOrigin` and `ExecError`, including
      `codec::Encode` and `codec::Decode`, so that `ExecResult` is
      en/decodable as well. This is required for a contract mocking feature
      (already prepared in drink:
      https://github.com/Cardinal-Cryptography/drink/pull/61). In more detail:
      `ExecResult` must be passed from runtime extension, through runtime
      interface, back to the pallet, which requires that it is serializable to
      bytes in some form (or implements some rare, auxiliary traits).
      
      **Impact on runtime size**: Since most of these traits is used directly
      in the pallet now, compiler should be able to throw it out (and thus we
      bring no new overhead). However, they are very useful in secondary tools
      like drink or other testing libraries.

      fix substrate-node-template generation (#2050) · 49c0f33b
      Daniel Moos authored
      
      
      # Description
      
      This PR updates the node-template-release generation binary as well as
      the `node-template-release.sh` file so that we can automatically push
      updates to the [substrate-node-template
      repository](https://github.com/substrate-developer-hub/substrate-node-template).
      I assume this part was not updated after the substrate project has been
      moved into the polkadot-sdk mono repo.
      
      # Adjustments
      - extend the `node-template-release.sh` to support the substrate
      child-folder
      - update the `SUBSTRATE_GIT_URL`
      - fix the Cargo.toml filter (so that it does not include any
      non-relevant .toml files)
      - set the workspace-edition to 2021
      
      # Note
      In order to auto-generate the artifacts [this
      line](https://github.com/paritytech/polkadot-sdk/blob/master/.gitlab/pipeline/build.yml#L320C15-L320C15)
      needs to be included in the build.yml script again. Since I do not have
      access to the (probably) internal gitlab environment I hope that someone
      with actual access can introduce that change.
      I also do not know how the auto-publish feature works so that would be
      another thing to add later on.
