      [xcm] Use `Weight::MAX` for `reserve_asset_deposited`, `receive_teleported_asset` benchmarks (#1726)
      
      # Description
      
      ## Summary
      
      Previously, the `pallet_xcm::do_reserve_transfer_assets` and
      `pallet_xcm::do_teleport_assets` functions relied on weight estimation
      for remote chain execution, which was based on guesswork derived from
      the local chain. This approach led to complications for runtimes that
      did not provide or support specific [XCM
      configurations](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76/polkadot/xcm/xcm-executor/src/config.rs#L43-L47)
      for `IsReserve` or `IsTeleporter`. Consequently, such runtimes had to
      resort to implementing hard-coded weights for XCM instructions like
      `reserve_asset_deposited` or `receive_teleported_asset` to support
      extrinsics such as `pallet_xcm::reserve_transfer_assets` and
      `pallet_xcm::teleport_assets`, which depended on remote weight
      estimation.
      
      The issue of remote weight estimation was addressed and resolved by
      [Pull Request
      #1645](https://github.com/paritytech/polkadot-sdk/pull/1645), which
      removed the need for remote weight estimation.
      
      ## Solution
      
      As a continuation of this improvement, the current PR proposes further
      cleanup by removing unnecessary hard-coded values and rectifying
      benchmark results with `Weight::MAX` that previously used
      `T::BlockWeights::get().max_block` as an override for unsupported XCM
      instructions like `ReserveAssetDeposited` and `ReceiveTeleportedAsset`.
      
      
      ## Questions
      
      - [x] Can we remove now also `Hardcoded till the XCM pallet is fixed`
      for `deposit_asset`? E.g. for AssetHubKusama
      [here](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76/cumulus/parachains/runtimes/assets/asset-hub-kusama/src/weights/xcm/mod.rs#L129-L134)
      - [x] Are comments like
      [this](https://github.com/paritytech/polkadot-sdk/blob/7cbe0c76/polkadot/runtime/kusama/src/weights/xcm/mod.rs#L94)
      `// Kusama doesn't support ReserveAssetDeposited, so this benchmark has
      a default weight` still relevant? Shouldnt be removed/changed?
      
      
      ## TODO
      
      - [x] `bench bot` regenerate xcm weights for all runtimes
      - [x] remove hard-coded stuff from system parachain weight files
      - [ ] when merged, open `polkadot-fellow/runtimes` PR
      
      ## References
      
      Fixes #1132
      Closes #1132

      Treasury spends various asset kinds (#1333) · cb944dc5
      Muharem Ismailov authored
      
      
      ### Summary 
      
      This PR introduces new dispatchables to the treasury pallet, allowing
      spends of various asset types. The enhanced features of the treasury
      pallet, in conjunction with the asset-rate pallet, are set up and
      enabled for Westend and Rococo.
      
      ### Westend and Rococo runtimes.
      
      Polkadot/Kusams/Rococo Treasury can accept proposals for `spends` of
      various asset kinds by specifying the asset's location and ID.
      
      #### Treasury Instance New Dispatchables:
      - `spend(AssetKind, AssetBalance, Beneficiary, Option<ValidFrom>)` -
      propose and approve a spend;
      - `payout(SpendIndex)` - payout an approved spend or retry a failed
      payout
      - `check_payment(SpendIndex)` - check the status of a payout;
      - `void_spend(SpendIndex)` - void previously approved spend;
      > existing spend dispatchable renamed to spend_local
      
      in this context, the `AssetKind` parameter contains the asset's location
      and it's corresponding `asset_id`, for example:
      `USDT` on `AssetHub`,
      ``` rust
      location = MultiLocation(0, X1(Parachain(1000)))
      asset_id = MultiLocation(0, X2(PalletInstance(50), GeneralIndex(1984)))
      ```
      
      the `Beneficiary` parameter is a `MultiLocation` in the context of the
      asset's location, for example
      ``` rust
      // the Fellowship salary pallet's location / account
      FellowshipSalaryPallet = MultiLocation(1, X2(Parachain(1001), PalletInstance(64)))
      // or custom `AccountId`
      Alice = MultiLocation(0, AccountId32(network: None, id: [1,...]))
      ```
      
      the `AssetBalance` represents the amount of the `AssetKind` to be
      transferred to the `Beneficiary`. For permission checks, the asset
      amount is converted to the native amount and compared against the
      maximum spendable amount determined by the commanding spend origin.
      
      the `spend` dispatchable allows for batching spends with different
      `ValidFrom` arguments, enabling milestone-based spending. If the
      expectations tied to an approved spend are not met, it is possible to
      void the spend later using the `void_spend` dispatchable.
      
      Asset Rate Pallet provides the conversion rate from the `AssetKind` to
      the native balance.
      
      #### Asset Rate Instance Dispatchables:
      - `create(AssetKind, Rate)` - initialize a conversion rate to the native
      balance for the given asset
      - `update(AssetKind, Rate)` - update the conversion rate to the native
      balance for the given asset
      - `remove(AssetKind)` - remove an existing conversion rate to the native
      balance for the given asset
      
      the pallet's dispatchables can be executed by the Root or Treasurer
      origins.
      
      ### Treasury Pallet
      
      Treasury Pallet can accept proposals for `spends` of various asset kinds
      and pay them out through the implementation of the `Pay` trait.
      
      New Dispatchables:
      - `spend(Config::AssetKind, AssetBalance, Config::Beneficiary,
      Option<ValidFrom>)` - propose and approve a spend;
      - `payout(SpendIndex)` - payout an approved spend or retry a failed
      payout;
      - `check_payment(SpendIndex)` - check the status of a payout;
      - `void_spend(SpendIndex)` - void previously approved spend;
      > existing spend dispatchable renamed to spend_local
      
      The parameters' types of the `spend` dispatchable exposed via the
      pallet's `Config` and allows to propose and accept a spend of a certain
      amount.
      
      An approved spend can be claimed via the `payout` within the
      `Config::SpendPeriod`. Clients provide an implementation of the `Pay`
      trait which can pay an asset of the `AssetKind` to the `Beneficiary` in
      `AssetBalance` units.
      
      The implementation of the Pay trait might not have an immediate final
      payment status, for example if implemented over `XCM` and the actual
      transfer happens on a remote chain.
      
      The `check_status` dispatchable can be executed to update the spend's
      payment state and retry the `payout` if the payment has failed.

      Delete full db directory with `purge-chain` subcommand (#1786) · d21113c1
      Sebastian Kunert authored
      Closes #1767 
      
      Until now the `purge-chain` command would only remove the `full`
      subfolder of the db folder. However there is also the `parachains` db
      that currently remains and can cause problems on node restart.
      
      Example wiht old code:
      ```
      polkadot purge-chain --database paritydb --base-path /tmp/some-folder
      Are you sure to remove "/tmp/some-folder/chains/polkadot/paritydb/full"? [y/N]: y
      "/tmp/some-folder/chains/polkadot/paritydb/full" removed.
      ```
      In this case `/tmp/some-folder/chains/polkadot/paritydb/parachains`
      would remain and might cause problem on node restart because of version
      conflicts as described in #1767. After this PR the whole
      `/tmp/some-folder/chains/polkadot/paritydb` folder will be deleted.

      [NPoS] Fix for Reward Deficit in the pool (#1255) · f820dc0a
      Ankan authored
      closes https://github.com/paritytech/polkadot-sdk/issues/158.
      partially addresses
      https://github.com/paritytech/polkadot-sdk/issues/226.
      
      Instead of fragile calculation of current balance by looking at `free
      balance - ED`, Nomination Pool now freezes ED in the pool reward account
      to restrict an account from going below minimum balance. This also has a
      nice side effect that if ED changes, we know how much is the imbalance
      in ED frozen in the pool and the current required ED. A pool operator
      can diligently top up the pool with the deficit in ED or vice versa,
      withdraw the excess they transferred to the pool.
      
      ## Notable changes
      - New call `adjust_pool_deposit`: Allows to top up the deficit or
      withdraw the excess deposited funds to the pool.
      - Uses Fungible trait (instead of Currency trait). Since NP was not
      doing any locking/reserving previously, no migration is needed for this.
      - One time migration of freezing ED from each of the existing pools (not
      very PoV friendly but fine for relay chain).

      Remove kusama and polkadot runtime crates (#1731) · bf90cb0b
      Bastian Köcher authored
      This pull request is removing the Kusama and Polkadot runtime crates. As
      still some crates dependent on the runtime crates, this pull request is
      doing some more changes.
      
      - It removes the `hostperfcheck` CLI command. This CLI command could
      compare the current node against the standard hardware by doing some
      checks. Later we added the hardware benchmark feature to Substrate. This
      hardware benchmark is running on every node startup and prints a warning
      if the current node is too slow. This makes this CLI command a duplicate
      that was also depending on the kusama runtime.
      
      - The pull request is removing the emulated integration tests that were
      requiring the Kusama or Polkadot runtime crates.

      rococo-runtime: `RococoGenesisExt` removed (#1490) · 50242a61
      Michal Kucharczyk authored
      [`RococoGenesisExt`](https://github.com/paritytech/polkadot-sdk/blob/a414ea75
      
      /polkadot/node/service/src/chain_spec.rs#L152-L171)
      is removed. It was the hack to allow overwriting
      `EpochDurationInBlocks`. Removal of `RococGenesisExt` prevents from
      manipulating the state to change the runtime constants.
      
      Changes:
      - Environment variable which controls the `time::EpochDurationInBlocks`
      value was added: `ROCOCO_EPOCH_DURATION` (epoch duration will be set to
      the value of env),
      - `10,100,600` versions of rococo-runtime are built in CI and put into `polkadot-debug` docker image.
      
      `rococo-runtime` building examples:
      - to build runtime for `versi_staging_testnet` which had
      EpochDurationInBlocks set to 100:
        ```
      ROCOCO_EPOCH_DURATION=100 cargo build --features=fast-runtime -p
      rococo-runtime
        ```
      - to build runtime for `wococo_development`
        ```
      ROCOCO_EPOCH_DURATION=10 cargo build --features=fast-runtime -p
      rococo-runtime
        ```
      - to build `versi-staging` chain spec:
        ```
      ROCOCO_EPOCH_DURATION=100 cargo run -p polkadot --features=fast-runtime
      -- build-spec --chain versi-staging --raw
        ```
      - to build `wococo-dev` chain spec:
        ```
      ROCOCO_EPOCH_DURATION=10 cargo run -p polkadot --features=fast-runtime
      -- build-spec --chain wococo-dev --raw
        ```
      
      It is also possible to change the epoch duration by replacing the `code` field in the chain spec with the hex dump of pre-built runtime wasm blob (because the epoch duration is hard-coded into wasm blob).

      XCM: Deprecate old functions (#1645) · e7d29bc3
      Gavin Wood authored
      Two old functions should be deprecated and have their code altered in
      line with capabilities of XCMv2 and above.
      
      This means we can use the proper `Unlimited` form of weight limit rather
      than guessing weight from the local chain.

      Refactor availability-recovery strategies (#1457) · 6f00edbc
      Alin Dima authored
      Refactors availability-recovery strategies to allow for easily adding
      new hotpaths and failover mechanisms.
      
      The new interface allows for chaining multiple `RecoveryStrategy`-es
      together, to cleanly express the relationship between them and share
      state and code where neccessary/possible:
      
      This was done in order to aid in implementing new hotpaths like
      [systematic chunks
      recovery](https://github.com/paritytech/polkadot-sdk/issues/598) and
      [fetching from approval
      checkers](https://github.com/paritytech/polkadot-sdk/issues/575).
      
      Thanks to this design, intermediate state can be shared between the
      strategies. For example, if the systematic chunks recovery retrieved
      less than the needed amount of chunks, pass them over to the next
      FetchChunks strategy, which will only need to recover the remaining
      number of chunks.
      
      Draft example of how a systematic chunk recovery strategy would look:
      https://github.com/paritytech/polkadot-sdk/commit/667d870bdf1470525d66c13929d5eac7249dd995
      (notice how easy it was to add and reuse code)
      
      Note that this PR doesn't itself add any new strategy, it should fully
      preserve backwards compatiblity in terms of functionality. Follow-up PRs
      to add new strategies will come.

      Disable Calls to Identity Pallet (#1476) · 771c3fbd
      joe petrowski authored
      This PR filters calls from the Identity pallet from all Relay Chain
      runtimes as preparation to move the identity state and logic to a system
      parachain within each network.
      
      After this change is deployed to a runtime, no more changes such as
      adding new sub-identities will be possible. The frozen state will be
      part of the genesis state of the system chain. After the system chain
      launches, the pallet and all state will be removed from each Relay
      Chain.
      
      Applications and UIs that render display information from this pallet
      will need to read from the system chain when it launches.

      allow governance body on parachain to have sovereign account (#1291) · cdbdbc75
      Xiliang Chen authored
      The goal is to allow Fellowship on Collective chain to have a sovereign
      account on Polkadot so that we can add it as an identity registrar. This
      will allow Fellows origin to be able to provide judgements for
      Fellowship members.
      
      This currently allow any body on any parachain including non system
      parachains to have sovereign account. I cannot think of any reason why
      that may be an issue but let me know if I should change it to filter
      only system parachains.
      
      [This](https://gist.github.com/xlc/ec61bfa4e9f6d62da27d30141ad2c72b) is
      the testing script.

      Remove Polkadot & Kusama native runtime (#1304) · 6079b6dd
      Bastian Köcher authored
      This pull request removes the Polkadot and Kusama native runtime from
      the polkadot node. This brings some implications with it:
      
      There are no more kusama/polkadot-dev chain specs available. We will
      need to write some tooling in the fellowship repo to provide them
      easily.
      
      The try-runtime job for polkadot & kusama is not available anymore as we
      don't have the dev chain specs anymore.
      
      Certain benchmarking commands will also not work until we migrate them
      to use a runtime api.
      
      Some crates in utils are still depending on the polkadot/kusama native
      runtime that will also need to be fixed.

      Revert #1409 partially (#1603) · 122086d3
      Vsevolod Stakhov authored
      Futures channels that are used by default has a side effect of
      `Sender::Clone` that efficiently increases the capacity of the bounded
      channel by one. This PR fixes the undesired backpressure removal that
      was caused by the #1409. This issue has been discovered by @sandreim
      during Versi testing and needs to be treated as critical that should not
      be included in any release without this reversion.
      
      This PR reverts the original behaviour.

      Implements a variable deposit base calculation for EPM signed submissions (#1547) · 614aa31b
      Gonçalo Pestana authored
      **Note**: This is a lift-and-shift PR from the old substrate and
      polkadot repos, both PRs have been reviewed and audited
      (https://github.com/paritytech/substrate/pull/13983,
      https://github.com/paritytech/polkadot/pull/7140)
      
      ---
      
      This PR implements a generic `BaseDeposit` calculation for signed
      submissions, based on the size of the submission queue.
      
      It adds a new associated type to EPM's config, `type SignedDepositBase`,
      that implements `Convert<usize, BalanceOf<T>>`, which is used to
      calculate the base deposit for signed submissions based on the size of
      the signed submissions queue.
      
      `struct GeometricDepositBase<Balance, Fixed, Inc>` implements the
      convert trait so that the deposit value increases as a geometric
      progression. The deposit base is calculated by `deposit_base =
      fixed_deposit_base * (1 + increase_factor)^n`, where `n` is the term of
      the progression (i.e. the number of signed submissions in the queue).
      `Fixed` and `Inc` generic params are getters for `Balance` and
      `IncreaseFactor` to compute the geometric progression. If
      `IncreaseFactor = 0`, then the signed deposit is constant and equal to
      `Fixed` regardless of the size of the queue.
      
      ### Runtime configs
      
      In Kusama, the progression with 10% increase without changing the
      current signed fixed deposit is: (term == size of the queue)
      
      Term 1: `1,333,333,332,000`
      Term 2: `1,333,333,332,000 * 1.10 = 1,466,666,665,200`
      Term 3: `1,333,333,332,000 * 1.10^2 = 1,613,333,331,200`
      Term 4: `1,333,333,332,000 * 1.10^3 = 1,774,666,664,320`
      Term 5: `1,333,333,332,000 * 1.10^4 = 1,952,133,330,752`
      Term 6: `1,333,333,332,000 * 1.10^5 = 2,147,346,663,827.20`
      Term 7: `1,333,333,332,000 * 1.10^6 = 2,362,081,330,210.92`
      Term 8: `1,333,333,332,000 * 1.10^7 = 2,598,289,463,231.01`
      Term 9: `1,333,333,332,000 * 1.10^8 = 2,858,118,409,554.11`
      Term 10: `1,333,333,332,000 * 1.10^9 = 3,143,930,250,509.52`
      
      Westend:
      
      Term 1: `2,000,000,000,000`
      Term 2: `2,000,000,000,000 * 1.10 = 2,200,000,000,000`
      Term 3: `2,000,000,000,000 * 1.10^2 = 2,420,000,000,000`
      Term 4: `2,000,000,000,000 * 1.10^3 = 2,662,000,000,000`
      Term 5: `2,000,000,000,000 * 1.10^4 = 2,928,200,000,000`
      Term 6: `2,000,000,000,000 * 1.10^5 = 3,221,020,000,000`
      Term 7: `2,000,000,000,000 * 1.10^6 = 3,543,122,000,000`
      Term 8: `2,000,000,000,000 * 1.10^7 = 3,897,434,200,000`
      Term 9: `2,000,000,000,000 * 1.10^8 = 4,287,177,620,000`
      Term 10: `2,000,000,000,000 * 1.10^9 = 4,715,895,382,000`
      
      and in Polkadot, the deposit increase is disabled in the current state
      of the PR, as the increase factor is 0% -- so nothing changes from the
      current behaviour.

      "Common good" vs "System" parachain clean up (#1406) · d569e728
      Branislav Kontur authored
      ## Summary 
      The term "common good parachain" has been abandoned in favor of "system
      parachain" - e.g. [Joe's speech at
      Decoded2023](https://youtu.be/CSO-ERHK2gY?t=456). This pull request
      tries to fix and align code with this vision.
      
      ## Impact
      
      The important change is implementation of `trait IsSystem` for `Id`
      [here](https://github.com/paritytech/polkadot-sdk/pull/1406/files#diff-0b7b4f5b962a18ce980354592b55ab2a27b5a2e9f6f8089ec803ca73853e8583R225-R229)
      where we changed condition from `< 1000` to `<= 1999`, which means that
      all parachain IDs bellow 1999 (included) are considered as "system
      parachain" IDs. This change has a direct impact on the following
      components:
      
      ####
      [ChildSystemParachainAsSuperuser](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/xcm-builder/src/origin_conversion.rs#L72-L88)
      This origin converter is used for allowing to process XCM `Transact`
      from "system parachain" on the relay chain - e.g. see [configuration for
      Kusama](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/runtime/kusama/src/xcm_config.rs#L92-L101).
      Only configured for Kusama, Westend, Rococo runtimes.
      
      **No need for this feature anymore.** See
      [comment](https://github.com/paritytech/polkadot-sdk/pull/1406#issuecomment-1708218715).
      
      ####
      [IsChildSystemParachain](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/xcm-builder/src/barriers.rs#L310-L317)
      `IsChildSystemParachain` is used with `AllowExplicitUnpaidExecutionFrom`
      barrier for checking XCM programs (they have to start with
      `UnpaidExecution` instruction).
      Only configured for Kusama, Westend, Rococo runtimes.
      
      **Overall the impact is low or mostly ok because it only allows unpaid
      execution for "system parachains" (e.g. AssetHub, BridgeHub...) on the
      relay chain.**
      
      ####
      [SiblingSystemParachainAsSuperuser](https://github.com/paritytech/polkadot-sdk/blob/master/polkadot/xcm/xcm-builder/src/origin_conversion.rs#L94-L114)
      
      Not used anywhere in `polkadot-sdk` repo.
      
      
      ## Unresolved Questions
      - [ ] constants `LOWEST_USER_ID` and `LOWEST_PUBLIC_ID` seem to express
      the same thing now, do we want to keep them both or deprecated one of
      them? If so, which one?
      - [x] determine impact for `ChildSystemParachainAsSuperuser`
      
      ## TODO
      
      - [ ] when merged here, open PR to the `polkadot-fellows`

      xcm-builder: PayOverXcm supports fallible convertors for asset kind and beneficiary conversion  (#1572)
      
      `PayOverXcm` type accepts two converters to transform the `AssetKind`
      and `Beneficiary` parameter types into recognized `xcm` types. In this
      PR, we've modified the bounds for these converters, transitioning from
      `Convert` to `TryConvert`.
      
      One such use case for this adjustment is when dealing with versioned xcm
      types for `AssetKind` and `Beneficiary`. These types might be not
      convertible to the latest xcm version, hence the need for fallible
      conversion.
