      Introduce approval-voting/distribution benchmark (#2621) · f9f88688
      Alexandru Gheorghe authored
      
      
      ## Summary
      Built on top of the tooling and ideas introduced in
      https://github.com/paritytech/polkadot-sdk/pull/2528, this PR introduces
      a synthetic benchmark for measuring and assessing the performance
      characteristics of the approval-voting and approval-distribution
      subsystems.
      
      Currently this allows, us to simulate the behaviours of these systems
      based on the following dimensions:
      ```
      TestConfiguration:
      # Test 1
      - objective: !ApprovalsTest
          last_considered_tranche: 89
          min_coalesce: 1
          max_coalesce: 6
          enable_assignments_v2: true
          send_till_tranche: 60
          stop_when_approved: false
          coalesce_tranche_diff: 12
          workdir_prefix: "/tmp"
          num_no_shows_per_candidate: 0
          approval_distribution_expected_tof: 6.0
          approval_distribution_cpu_ms: 3.0
          approval_voting_cpu_ms: 4.30
        n_validators: 500
        n_cores: 100
        n_included_candidates: 100
        min_pov_size: 1120
        max_pov_size: 5120
        peer_bandwidth: 524288000000
        bandwidth: 524288000000
        latency:
          min_latency:
            secs: 0
            nanos: 1000000
          max_latency:
            secs: 0
            nanos: 100000000
        error: 0
        num_blocks: 10
      ```
      
      ## The approach
      1. We build a real overseer with the real implementations for
      approval-voting and approval-distribution subsystems.
      2. For a given network size, for each validator we pre-computed all
      potential assignments and approvals it would send, because this a
      computation heavy operation this will be cached on a file on disk and be
      re-used if the generation parameters don't change.
      3. The messages will be sent accordingly to the configured parameters
      and those are split into 3 main benchmarking scenarios.
      
      ## Benchmarking scenarios
      
      ### Best case scenario *approvals_throughput_best_case.yaml*
      It send to the approval-distribution only the minimum required tranche
      to gathered the needed_approvals, so that a candidate is approved.
      
      ### Behaviour in the presence of no-shows *approvals_no_shows.yaml*
      It sends the tranche needed to approve a candidate when we have a
      maximum of *num_no_shows_per_candidate* tranches with no-shows for each
      candidate.
      
      ### Maximum throughput *approvals_throughput.yaml*
      It sends all the tranches for each block and measures the used CPU and
      necessary network bandwidth. by the approval-voting and
      approval-distribution subsystem.
      
      ## How to run it
      ```
      cargo run -p polkadot-subsystem-bench --release -- test-sequence --path polkadot/node/subsystem-bench/examples/approvals_throughput.yaml
      ```
      
      ## Evaluating performance
      ### Use the real subsystems metrics
      If you follow the steps in
      https://github.com/paritytech/polkadot-sdk/tree/master/polkadot/node/subsystem-bench#install-grafana
      for installing locally prometheus and grafana, all real metrics for the
      `approval-distribution`, `approval-voting` and overseer are available.
      E.g:

      ### Profile with pyroscope
      1. Setup pyroscope following the steps in
      https://github.com/paritytech/polkadot-sdk/tree/master/polkadot/node/subsystem-bench#install-pyroscope,
      then run any of the benchmark scenario with `--profile` as the
      arguments.
      2. Open the pyroscope dashboard in grafana, e.g:
      <img width="2544" alt="Screenshot 2024-01-09 at 17 09 58"
      src="https://github.com/paritytech/polkadot-sdk/assets/49718502/58f50c99-a910-4d20-951a-8b16639303d9">
      
      
      
      ### Useful  logs
      1. Network bandwidth requirements:
      ```
      Payload bytes received from peers: 503993 KiB total, 50399 KiB/block
      Payload bytes sent to peers: 629971 KiB total, 62997 KiB/block
      ```
      
      2. Cpu usage by the approval-distribution/approval-voting subsystems.
      ```
      approval-distribution CPU usage 84.061s
      approval-distribution CPU usage per block 8.406s
      approval-voting CPU usage 96.532s
      approval-voting CPU usage per block 9.653s
      ```
      
      3. Time passed until a given block is approved
      ```
       Chain selection approved  after 3500 ms hash=0x0101010101010101010101010101010101010101010101010101010101010101
      Chain selection approved  after 4500 ms hash=0x0202020202020202020202020202020202020202020202020202020202020202
      ```
      
      ### Using benchmark to quantify improvements from
      https://github.com/paritytech/polkadot-sdk/pull/1178 +
      https://github.com/paritytech/polkadot-sdk/pull/1191
      
      Using a versi-node we compare the scenarios where all new optimisations
      are disabled with a scenarios where tranche0 assignments are sent in a
      single message and a conservative simulation where the coalescing of
      approvals gives us just 50% reduction in the number of messages we send.
      
      Overall, what we see is a speedup of around 30-40% in the time it takes
      to process the necessary messages and a 30-40% reduction in the
      necessary bandwidth.

      ## TODOs
      [x] Polish implementation.
      [x] Use what we have so far to evaluate
      https://github.com/paritytech/polkadot-sdk/pull/1191 before merging.
      [x] List of features and additional dimensions we want to use for
      benchmarking.
      [x] Run benchmark on hardware similar with versi and kusama nodes.
      [ ] Add benchmark to be run in CI for catching regression in
      performance.
      [ ] Rebase on latest changes for network emulation.

      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)

      <h2>[<code>0.32.0-beta.5</code>] - 2024-01-15</h2>
      <p><strong>Note:</strong></p>
      <ul>
      <li>This is the beta of the upcoming <code>v0.32.0</code> release.
      This version is not production ready yet and might contain serious bugs.
      Please use this only for experimentation or at your own risk.</li>
      <li>Performance tests indicated that the new register-machine bytecode
      based
      Wasmi engine performance is very sensitive to hardware or OS specifics
      which may lead to very different performance characteristics.
      <ul>
      <li>We are working on fixing this until the stable release.</li>
      <li>Measurements concluded that execution performance can be equal or
      sometimes
      even surpass Wasm3 execution performance.</li>
      </ul>
      </li>
      </ul>
      <h3>Added</h3>
      <ul>
      <li>Added a new execution engine based on register-machine bytecode. (<a
      href="https://redirect.github.com/paritytech/wasmi/pull/729">paritytech/wasmi#729</a>)
      <ul>
      <li>The register-machine Wasmi <code>Engine</code> executes roughly
      80-100% faster and
      compiles roughly 30% slower according to benchmarks conducted so
      far.</li>
      </ul>
      </li>
      <li>Added <code>Module::new_unchecked</code> API. (<a
      href="https://redirect.github.com/paritytech/wasmi/pull/829">paritytech/wasmi#829</a>)
      <ul>
      <li>This allows to compile a Wasm module without Wasm validation which
      can be useful
      when users know that their inputs are valid Wasm binaries.</li>
      <li>This improves Wasm compilation performance for faster startup times
      by roughly 10-20%.</li>
      </ul>
      </li>
      <li>Added Wasm compilation modes. (<a
      href="https://redirect.github.com/paritytech/wasmi/pull/844">paritytech/wasmi#844</a>)
      <ul>
      <li>When using <code>Module::new</code> Wasmi eagerly compiles Wasm
      bytecode into Wasmi bytecode
      which is optimized for efficient execution. However, this compilation
      can become very
      costly especially for large Wasm binaries.</li>
      <li>The solution to this problem is to introduce new compilation modes,
      namely:
      <ul>
      <li><code>CompilationMode::Eager</code>: Eager compilation, what Wasmi
      did so far. (default)</li>
      <li><code>CompilationMode::LazyTranslation</code>: Eager Wasm validation
      and lazy Wasm translation.</li>
      <li><code>CompilationMode::Lazy</code>: Lazy Wasm validation and
      translation.</li>
      </ul>
      </li>
      <li>Benchmarks concluded that
      <ul>
      <li><code>CompilationMode::LazyTanslation</code>: Usually improves
      startup performance by a factor of 2 to 3.</li>
      <li><code>CompilationMode::Lazy</code>: Usually improves startup
      performance by a factor of up to 27.</li>
      </ul>
      </li>
      <li>Note that <code>CompilationMode::Lazy</code> can lead to partially
      validated Wasm modules
      which can introduce non-determinism when using different Wasm
      implementations.
      Therefore users should know what they are doing when using
      <code>CompilationMode::Lazy</code> if this is a concern.</li>
      <li>Enable lazy Wasm compilation with:
      <pre lang="rust"><code>let mut config = wasmi::Config::default();
      </code></pre>
      </li>
      </ul>
      </li>
      </ul>

      [xcm] Fix `SovereignPaidRemoteExporter` and `DepositAsset` handling (#3157) · 6ea472ad
      Branislav Kontur authored
      This PR addresses two issues:
      - It modifies `DepositAsset`'s asset filter from `All` to
      `AllCounted(1)` to prevent potentially charging excessive weight/fees.
      This adjustment avoids situations where fees could be calculated based
      on the count of assets, as illustrated
      [here](https://github.com/paritytech/polkadot-sdk/blob/master/cumulus/parachains/runtimes/bridge-hubs/bridge-hub-rococo/src/weights/xcm/mod.rs#L38-L46).
      - It encapsulates `DepositAsset` with `SetAppendix` to ensure that
      `fees` are not trapped in any case. For instance, this prevents issues
      when `ExportXcm::validate` encounters an error during the processing of
      `ExportMessage`.

      xcm-executor: DepositReserveAsset charges delivery fees from inner assets (#3142) · 5354097a
      Adrian Catangiu authored
      
      
      This fix aims to solve an issue in Kusama that resulted in failed
      reserve asset transfers.
      
      During multi-hop XCMs, like reserve asset transfers where the reserve is
      not the sender nor the destination, but a third remote chain, the origin
      is not available to pay for delivery fees out of their account directly,
      so delivery fees should be paid out of transferred assets.
      
      This commit also adds an xcm-emulator regression test that validates
      this scenario is now working.

      Branislav Kontur authored
      [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`.
      
      
      ## For reviewers
      
      Relevant changes can be found here:
      - `substrate/frame/support/procedural/src/lib.rs` 
      -  `substrate/frame/support/procedural/src/pallet/parse/composite.rs`
      -  `substrate/frame/support/procedural/src/pallet/expand/composite.rs`
      -
      `substrate/frame/support/procedural/src/construct_runtime/expand/composite_helper.rs`
      -

      -
      `substrate/frame/support/procedural/src/construct_runtime/expand/freeze_reason.rs`
      - `substrate/frame/support/src/traits/misc.rs`
      
      And the rest of the files is just about removed `MaxHolds` from
      `pallet_balances`
      
      ## Next steps
      
      Do the same for `MaxFreezes`

      Some more work regarding XCMv4. Two limits from v3 were not transferred
      over, those are:
      - The instructions limit
      - The number of assets limit
      Both of these are now in v4.
      
      For some reason `AssetInstance` increased in size, don't know why CI
      didn't catch that before.
