      Fix nostd build of several crates (#4060) · 7a2c9d4a
      Oliver Tale-Yazdi authored
      
      
      Preparation for https://github.com/paritytech/polkadot-sdk/pull/3935
      
      Changes:
      - Add some `default-features = false` for the case that a crate and that
      dependency both support nostd builds.
      - Shuffle files around of some benchmarking-only crates. These
      conditionally disabled the `cfg_attr` for nostd and pulled in libstd.
      Example [here](https://github.com/ggwpez/zepter/pull/95). The actual
      logic is moved into a `inner.rs` to preserve nostd capability of the
      crate in case the benchmarking feature is disabled.
      - Add some `use sp_std::vec` where needed.
      - Remove some `optional = true` in cases where it was not optional.
      - Removed one superfluous `cfg_attr(not(feature = "std"), no_std..`.
      
      All in all this should be logical no-op.

      [FRAME] Runtime Omni Bencher (#3512) · 9543d314
      Oliver Tale-Yazdi authored
      
      
      This MR contains two major changes and some maintenance cleanup.  
      
      ## 1. Free Standing Pallet Benchmark Runner
      
      Closes https://github.com/paritytech/polkadot-sdk/issues/3045, depends
      on your runtime exposing the `GenesisBuilderApi` (like
      https://github.com/paritytech/polkadot-sdk/pull/1492).
      
      Introduces a new binary crate: `frame-omni-bencher`.  
      It allows to directly benchmark a WASM blob - without needing a node or
      chain spec.
      
      This makes it much easier to generate pallet weights and should allow us
      to remove bloaty code from the node.
      It should work for all FRAME runtimes that dont use 3rd party host calls
      or non `BlakeTwo256` block hashing (basically all polkadot parachains
      should work).
      
      It is 100% backwards compatible with the old CLI args, when the `v1`
      compatibility command is used. This is done to allow for forwards
      compatible addition of new commands.
      
      ### Example (full example in the Rust docs)
      
      Installing the CLI:
      ```sh
      cargo install --locked --path substrate/utils/frame/omni-bencher
      frame-omni-bencher --help
      ```
      
      Building the Westend runtime:
      ```sh
      cargo build -p westend-runtime --release --features runtime-benchmarks
      ```
      
      Benchmarking the runtime:
      ```sh
      frame-omni-bencher v1 benchmark pallet --runtime target/release/wbuild/westend-runtime/westend_runtime.compact.compressed.wasm --all
      ```
      
      ## 2. Building the Benchmark Genesis State in the Runtime
      
      Closes https://github.com/paritytech/polkadot-sdk/issues/2664
      
      This adds `--runtime` and `--genesis-builder=none|runtime|spec`
      arguments to the `benchmark pallet` command to make it possible to
      generate the genesis storage by the runtime. This can be used with both
      the node and the freestanding benchmark runners. It utilizes the new
      `GenesisBuilder` RA and depends on having
      https://github.com/paritytech/polkadot-sdk/pull/3412 deployed.
      
      ## 3. Simpler args for `PalletCmd::run`
      
      You can do three things here to integrate the changes into your node:
      - nothing: old code keeps working as before but emits a deprecated
      warning
      - delete: remove the pallet benchmarking code from your node and use the
      omni-bencher instead
      - patch: apply the patch below and keep using as currently. This emits a
      deprecated warning at runtime, since it uses the old way to generate a
      genesis state, but is the smallest change.
      
      ```patch
      runner.sync_run(|config| cmd
      -    .run::<HashingFor<Block>, ReclaimHostFunctions>(config)
      +    .run_with_spec::<HashingFor<Block>, ReclaimHostFunctions>(Some(config.chain_spec))
      )
      ```
      
      ## 4. Maintenance Change
      - `pallet-nis` get a `BenchmarkSetup` config item to prepare its
      counterparty asset.
      - Add percent progress print when running benchmarks.
      - Dont immediately exit on benchmark error but try to run as many as
      possible and print errors last.

      `GenesisConfig` presets for runtime (#2714) · f910a15c
      Michal Kucharczyk authored
      The runtime now can provide a number of predefined presets of
      `RuntimeGenesisConfig` struct. This presets are intended to be used in
      different deployments, e.g.: `local`, `staging`, etc, and should be
      included into the corresponding chain-specs.
      
      Having `GenesisConfig` presets in runtime allows to fully decouple node
      from runtime types (the problem is described in #1984).
      
      **Summary of changes:**
      - The `GenesisBuilder` API was adjusted to enable this functionality
      (and provide better naming - #150):
         ```rust
          fn preset_names() -> Vec<PresetId>;
      fn get_preset(id: Option<PresetId>) -> Option<serde_json::Value>;
      //`None` means default
          fn build_state(value: serde_json::Value);
          pub struct PresetId(Vec<u8>);
         ```
      
      - **Breaking change**: Old `create_default_config` method was removed,
      `build_config` was renamed to `build_state`. As a consequence a node
      won't be able to interact with genesis config for older runtimes. The
      cleanup was made for sake of API simplicity. Also IMO maintaining
      compatibility with old API is not so crucial.
      - Reference implementation was provided for `substrate-test-runtime` and
      `rococo` runtimes. For rococo new
      [`genesis_configs_presets`](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/polkadot/runtime/rococo/src/genesis_config_presets.rs#L530)
      module was added and is used in `GenesisBuilder`
      [_presets-related_](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/polkadot/runtime/rococo/src/lib.rs#L2462-L2485)
      methods.
      
      - The `chain-spec-builder` util was also improved and allows to
      ([_doc_](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/substrate/bin/utils/chain-spec-builder/src/lib.rs#L19)):
         - list presets provided by given runtime (`list-presets`),
      - display preset or default config provided by the runtime
      (`display-preset`),
         - build chain-spec using named preset (`create ... named-preset`),
      
      
      - The `ChainSpecBuilder` is extended with
      [`with_genesis_config_preset_name`](https://github.com/paritytech/polkadot-sdk/blob/3b41d66b/substrate/client/chain-spec/src/chain_spec.rs#L447)
      method which allows to build chain-spec using named preset provided by
      the runtime. Sample usage on the node side
      [here](https://github.com/paritytech/polkadot-sdk/blob/2caffaae
      
      /polkadot/node/service/src/chain_spec.rs#L404).
      
      Implementation of #1984.

      migrations: prevent accidentally using unversioned migrations instead of... · e5427969
      Dastan authored
      migrations: prevent accidentally using unversioned migrations instead of `VersionedMigration` (#3835)
      
      closes #1324 
      
      #### Problem
      Currently, it is possible to accidentally use inner unversioned
      migration instead of `VersionedMigration` since both implement
      `OnRuntimeUpgrade`.
      
      #### Solution
      
      With this change, we make it clear that value of `Inner` is not intended
      to be used directly. It is achieved by bounding `Inner` to new trait
      `UncheckedOnRuntimeUpgrade`, which has the same interface (except
      `unchecked_` prefix) as `OnRuntimeUpgrade`.
      
      #### `try-runtime` functions
      
      Since developers can implement `try-runtime` for `Inner` value in
      `VersionedMigration` and have custom logic for it, I added the same
      `try-runtime` functions to `UncheckedOnRuntimeUpgrade`. I looked for a
      ways to not duplicate functions, but couldn't find anything that doesn't
      significantly change the codebase. So I would appreciate If you have any
      suggestions to improve this

      Fix parachain upgrade scheduling when done by the owner/root (#3341) · 12eb285d
      Bastian Köcher authored
      When using `schedule_code_upgrade` to change the code of a parachain in
      the relay chain runtime, we had already fixed to not set the `GoAhead`
      signal. This was done to not brick any parachain after the upgrade,
      because they were seeing the signal without having any upgrade prepared.
      The remaining problem is that the parachain code is only upgraded after
      a parachain header was enacted, aka the parachain made some progress.
      However, this is quite complicated if the parachain is bricked (which is
      the most common scenario why to manually schedule a code upgrade). Thus,
      this pull request replaces `SetGoAhead` with `UpgradeStrategy` to signal
      to the logic kind of strategy want to use. The strategies are either
      `SetGoAheadSignal` or `ApplyAtExpectedBlock`. `SetGoAheadSignal` sets
      the go ahead signal as before and awaits a parachain block.
      `ApplyAtExpectedBlock` schedules the upgrade and applies it directly at
      the `expected_block` without waiting for the parachain to make any kind
      of progress.

      Extrinsic to restore corrupt staking ledgers (#3706) · bbdbeb7e
      Gonçalo Pestana authored
      This PR adds a new extrinsic `Call::restore_ledger ` gated by
      `StakingAdmin` origin that restores a corrupted staking ledger. This
      extrinsic will be used to recover ledgers that were affected by the
      issue discussed in
      https://github.com/paritytech/polkadot-sdk/issues/3245.
      
      The extrinsic will re-write the storage items associated with a stash
      account provided as input parameter. The data used to reset the ledger
      can be either i) fetched on-chain or ii) partially/totally set by the
      input parameters of the call.
      
      In order to use on-chain data to restore the staking locks, we need a
      way to read the current lock in the balances pallet. This PR adds a
      `InspectLockableCurrency` trait and implements it in the pallet
      balances. An alternative would be to tightly couple staking with the
      pallet balances but that's inelegant (an example of how it would look
      like in [this
      branch](https://github.com/paritytech/polkadot-sdk/tree/gpestana/ledger-badstate-clean_tightly)).

      corrupted ledgers in Polkadot and Kusama. You can verify it here

      **Changes introduced**
      - Adds `Call::restore_ledger ` extrinsic to recover a corrupted ledger;
      - Adds trait `frame_support::traits::currency::InspectLockableCurrency`
      to allow external pallets to read current locks given an account and
      lock ID;
      - Implements the `InspectLockableCurrency` in the pallet-balances.
      - Adds staking locks try-runtime checks

      XCM Fee Payment Runtime API (#3607) · 3c972fc1
      Pavel Orlov authored
      
      
      The PR provides API for obtaining:
      - the weight required to execute an XCM message,
      - a list of acceptable `AssetId`s for message execution payment,
      - the cost of the weight in the specified acceptable `AssetId`.
      
      It is meant to address an issue where one has to guess how much fee to
      pay for execution. Also, at the moment, a client has to guess which
      assets are acceptable for fee execution payment.
      See the related issue
      https://github.com/paritytech/polkadot-sdk/issues/690.
      With this API, a client is supposed to query the list of the supported
      asset IDs (in the XCM version format the client understands), weigh the
      XCM program the client wants to execute and convert the weight into one
      of the acceptable assets. Note that the client is supposed to know what
      program will be executed on what chains. However, having a small
      companion JS library for the pallet-xcm and xtokens should be enough to
      determine what XCM programs will be executed and where (since these

      Migrate parachain swaps to Coretime (#3714) · 90234543
      Tsvetomir Dimitrov authored
      This PR notifies broker pallet for any parachain slot swaps performed on
      the relay chain. This is achieved by registering an `OnSwap` for the the
      `coretime` pallet. The hook sends XCM message to the broker chain and
      invokes a new extrinsic `swap_leases` which updates `Leases` storage
      item (which keeps the legacy parachain leases).
      
      I made two assumptions in this PR:
      1.
      [`Leases`](https://github.com/paritytech/polkadot-sdk/blob/4987d798/substrate/frame/broker/src/lib.rs#L120)
      in `broker` pallet and
      [`Leases`](https://github.com/paritytech/polkadot-sdk/blob/4987d798
      
      /polkadot/runtime/common/src/slots/mod.rs#L118)
      in `slots` pallet are in sync.
      2. `swap_leases` extrinsic from `broker` pallet can be triggered only by
      root or by the XCM message from the relay chain. If not - the extrinsic
      will generate an error and do nothing.
      
      As a side effect from the changes `OnSwap` trait is moved from
      runtime/common/traits.rs to runtime/parachains. Otherwise it is not
      accessible from `broker` pallet.
      
      Closes https://github.com/paritytech/polkadot-sdk/issues/3552

      Revert `SendXcmOrigin` in Rococo & Westend (#2571) · 01d65f6b
      Alejandro Martinez Andres authored
      
      
      Based on issue
      [#2512](https://github.com/paritytech/polkadot-sdk/issues/2512), it
      seems that some ecosystem teams are using these networks to set up their
      staging environments and test certain use cases, some of them involving
      sending XCMs from the relay with origins not allowed in the current
      configuration.
      
      This change reverts the configuration of `SendXcmOrigin`.
