      [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`.

      contracts: Fix printing the `Schedule` (#3021) · 5e5341da
      Alexander Theißen authored
      Printing the `Schedule` is a useful debugging tool and general sanity
      check. It is much more easy to interpret than the raw weights.
      
      The printing relied on using `println` and hence was only available from
      the native runtime. This is no longer available. This is why in this PR
      we switch to using `log` which works from Wasm.
      
      I made sure that the `WeightDebug` is only derived when
      `runtime-benchmarks` is set so that we don't increase the size of the
      binary.
      
      Some other changes were necessary to make this actually work inside the
      runtime. For example, I needed to remove `format!` and usage of floats.
      
      Please note that this removed the decimal from the number because
      truncating the fraction without using floats would not be easy and would
      require custom code. I think the precision here is sufficient.
      
      This is how the output looks like now:
      ```

      Update Wasm benchmarks (#2957) · e02c5204
      Robin Freyler authored
      In https://github.com/paritytech/polkadot-sdk/pull/2941 we found out
      that the new Wasmi (register) is very effective at optimizing away
      certain benchmark bytecode constructs in a way that created an unfair
      advantage over Wasmi (stack) which yielded our former benchmarks to be
      ineffective at properly measuring the performance impact.
      
      This PR adjusts both affected benchmarks to fix the stated problems.
      Affected are
      - `instr_i64const` -> `instr_i64add`: Renamed since it now measures the
      performance impact of the Wasm `i64.add` instruction with locals as
      inputs and outputs. This makes it impossible for Wasmi (register) to
      aggressively optimize away the entire function body (as it previously
      did) but still provides a way for Wasmi (register) to shine with its
      register based execution model.
      - `call_with_code_per_byte`: Now uses `local.get` instead of `i32.const`
      for the `if` condition which prevents Wasmi (register) to aggressively
      optimizing away whole parts of the `if` creating an unfair advantage.

      XCMv4 (#1230) · 8428f678
      Francisco Aguirre authored
      
      
      # Note for reviewer
      
      Most changes are just syntax changes necessary for the new version.
      Most important files should be the ones under the `xcm` folder.
      
      # Description 
      
      Added XCMv4.
      
      ## Removed `Multi` prefix
      The following types have been renamed:
      - MultiLocation -> Location
      - MultiAsset -> Asset
      - MultiAssets -> Assets
      - InteriorMultiLocation -> InteriorLocation
      - MultiAssetFilter -> AssetFilter
      - VersionedMultiAsset -> VersionedAsset
      - WildMultiAsset -> WildAsset
      - VersionedMultiLocation -> VersionedLocation
      
      In order to fix a name conflict, the `Assets` in `xcm-executor` were
      renamed to `HoldingAssets`, as they represent assets in holding.
      
      ## Removed `Abstract` asset id
      
      It was not being used anywhere and this simplifies the code.
      
      Now assets are just constructed as follows:
      
      ```rust
      let asset: Asset = (AssetId(Location::new(1, Here)), 100u128).into();
      ```
      
      No need for specifying `Concrete` anymore.
      
      ## Outcome is now a named fields struct
      
      Instead of
      
      ```rust
      pub enum Outcome {
        Complete(Weight),
        Incomplete(Weight, Error),
        Error(Error),
      }
      ```
      
      we now have
      
      ```rust
      pub enum Outcome {
        Complete { used: Weight },
        Incomplete { used: Weight, error: Error },
        Error { error: Error },
      }
      ```
      
      ## Added Reanchorable trait
      
      Now both locations and assets implement this trait, making it easier to
      reanchor both.
      
      ## New syntax for building locations and junctions
      
      Now junctions are built using the following methods:
      
      ```rust
      let location = Location {
          parents: 1,
          interior: [Parachain(1000), PalletInstance(50), GeneralIndex(1984)].into()
      };
      ```
      
      or
      
      ```rust
      let location = Location::new(1, [Parachain(1000), PalletInstance(50), GeneralIndex(1984)]);
      ```
      
      And they are matched like so:
      
      ```rust
      match location.unpack() {
        (1, [Parachain(id)]) => ...
        (0, Here) => ...,
        (1, [_]) => ...,
      }
      ```
      
      This syntax is mandatory in v4, and has been also implemented for v2 and
      v3 for easier migration.
      
      This was needed to make all sizes smaller.
      
      # TODO
      - [x] Scaffold v4
      - [x] Port github.com/paritytech/polkadot/pull/7236
      - [x] Remove `Multi` prefix
      - [x] Remove `Abstract` asset id

      Fix clippy lints behind feature gates and add new CI step all features (#2569) · d68868f6
      Dónal Murray authored
      
      
      Many clippy lints usually enforced by `-Dcomplexity` and `-Dcorrectness`
      are not caught by CI as they are gated by `features`, like
      `runtime-benchmarks`, while the clippy CI job runs with only the default
      features for all targets.
      
      This PR also adds a CI step to run clippy with `--all-features` to
      ensure the code quality is maintained behind feature gates from now on.
      
      To improve local development, clippy lints are downgraded to warnings,
      but they still will result in an error at CI due to the `-Dwarnings`
      rustflag.

      see #2189
      
      This PR does the following:
      - Bring the user api functions into a new pallet-contracts-uapi (They
      are currently defined in ink!
      [here])(https://github.com/paritytech/ink/blob/master/crates/env/src/engine/on_chain/ext.rs
      
      )
      - Add older api versions and unstable to the user api trait.
      - Remove pallet-contracts-primitives and bring the types it defined in
      uapi / pallet-contracts
      - Add the infrastructure to build fixtures from Rust files and test it
      works by replacing `dummy.wat` and `call.wat`
      - Move all the doc from wasm/runtime.rs to pallet-contracts-uapi.
      
      This will be done in a follow up:
      - convert the rest of the test from .wat to rust
      - bring risc-v uapi up to date with wasm
      - finalize the uapi host fns, making sure everything is codegen from the
      source host fns in pallet-contracts

      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.

      Enable mocking contracts (#1331) · d8d90a82
      Piotr Mikołajczyk authored
      # Description
      This PR introduces two changes:
      - the previous `Tracing` trait has been modified to accept contract
      address instead of code hash (seems to be way more convenient)
      - a new trait `CallInterceptor` that allows intercepting contract calls;
      in particular the default implementation for `()` will just proceed in a
      standard way (after compilation optimizations, there will be no
      footprint of that); however, implementing type might decide to mock
      invocation and return `ExecResult` instead
      
      Note: one might try merging `before_call` and `intercept_call`. However,
      IMHO this would be bad, since it would mix two completely different
      abstractions - tracing without any effects and actual intervention into
      execution process.
      
      This will unblock working on mocking contracts utility in drink and
      similar tools (https://github.com/Cardinal-Cryptography/drink/issues/33)

      contracts: Fix incorrect storage alias in mirgration (#1687) · e8da3207
      Kevin Wang authored
      
      
      # Description
      
      We are recently trying to upgrade our Substrate version from
      `polkadot-v0.9.43` to `polkadot-v1.0.0` and we noticed a critical issue:
      all deployed contracts seem to be experiencing a `CodeNotFound` error.
      After a thorough investigation, it appears that the root cause of this
      issue lies in the mismatch between the storage alias of `CodeInfoOf<T>`
      in the migration and its original definition.
      
      This PR corrects the storage alias to align it with its original
      definition
      
      I am uncertain about the proper approach for adding tests to this
      change. Would the team consider taking over this PR to bring it to
      completion?

      contracts: Run start function (#1367) · c879d1d5
      Alexander Theißen authored
      Fixes #116 
      
      Start function wasn't allowed in a contract. Now it is allowed and is
      being run.
      
      It was disallowed because it is not used by Rust and supporting it made
      the code more complex. However, not running the start function violates
      the wasm standard. This makes life harder for some languages (see linked
      ticket).
