      Branislav Kontur authored 
      This PR addresses several minor issues:
- Fixes the symlink for `asset-hub-rococo.json` chainspec.
- Corrects the `asset-hub-rococo-genesis` invulnerables setup.
- Relocates common bash functions for bridge testing to a separate file
`bridges_common.sh`.

      `xcm`: Change `TypeInfo::path` to not include `staging` (#1948) · f3bf5c1a
      Bastian Köcher authored 
      The `xcm` crate was renamed to `staging-xcm` to be able to publish it to
crates.io as someone as squatted `xcm`. The problem with this rename is
that the `TypeInfo` includes the crate name which ultimately lands in
the metadata. The metadata is consumed by downstream users like
`polkadot-js` or people building on top of `polkadot-js`. These people
are using the entire `path` to find the type in the type registry. Thus,
their code would break as the type path would now be [`staging_xcm`,
`VersionedXcm`] instead of [`xcm`, `VersionedXcm`]. This pull request
fixes this by renaming the path segment `staging_xcm` to `xcm`.

This requires: https://github.com/paritytech/scale-info/pull/197

      Introduce XcmFeesToAccount fee manager (#1234) · 3dece311
      Keith Yeung authored 
      

Combination of paritytech/polkadot#7005, its addon PR
paritytech/polkadot#7585 and its companion paritytech/cumulus#2433.

This PR introduces a new XcmFeesToAccount struct which implements the
`FeeManager` trait, and assigns this struct as the `FeeManager` in the
XCM config for all runtimes.

The struct simply deposits all fees handled by the XCM executor to a
specified account. In all runtimes, the specified account is configured
as the treasury account.

XCM __delivery__ fees are now being introduced (unless the root origin
is sending a message to a system parachain on behalf of the originating
chain).

# Note for reviewers

Most file changes are tests that had to be modified to account for the
new fees.
Main changes are in:
- cumulus/pallets/xcmp-queue/src/lib.rs <- To make it track the delivery
fees exponential factor
- polkadot/xcm/xcm-builder/src/fee_handling.rs <- Added. Has the
FeeManager implementation
- All runtime xcm_config files <- To add the FeeManager to the XCM
configuration

# Important note

After this change, instructions that create and send a new XCM (Query*,
Report*, ExportMessage, InitiateReserveWithdraw, InitiateTeleport,
DepositReserveAsset, TransferReserveAsset, LockAsset and RequestUnlock)
will require the corresponding origin account in the origin register to
pay for transport delivery fees, and the onward message will fail to be
sent if the origin account does not have the required amount. This
delivery fee is on top of what we already collect as tx fees in
pallet-xcm and XCM BuyExecution fees!

Wallet UIs that want to expose the new delivery fee can do so using the
formula:

```
delivery_fee_factor * (base_fee + encoded_msg_len * per_byte_fee)
```

where the delivery fee factor can be obtained from the corresponding
pallet based on which transport you are using (UMP, HRMP or bridges),
the base fee is a constant, the encoded message length from the message
itself and the per byte fee is the same as the configured per byte fee
for txs (i.e. `TransactionByteFee`).

cumulus: add asset-hub-rococo runtime based on asset-hub-kusama and add asset-bridging support to it (#1215)

This commit adds Rococo Asset Hub dedicated runtime so we can test new
features here, before merging them in Kusama Asset Hub.
Also adds one such feature: asset transfer over bridge (Rococo AssetHub
<> Wococo AssetHub)

- clone `asset-hub-kusama-runtime` -> `asset-hub-rococo-runtime`
- make it use Rococo primitives, names, assets, constants, etc
- add asset-transfer-over-bridge support to Rococo AssetHub <> Wococo
AssetHub

Fixes #1128

      Xcm emulator nits (#1649) · cfb29254
      Branislav Kontur authored 
      # Desription

## Summary 

This PR introduces several nits and tweaks to xcm emulator tests for
system parachains.

## Explanation

**Deduplicate `XcmPallet::send(` with root origin code**
- Introduced `send_transact_to_parachain` which could be easily reuse
for scenarios like _governance call from relay chain to parachain_.

**Refactor `send_transact_sudo_from_relay_to_system_para_works`**
- Test covered just one use-case which was moved to the
`do_force_create_asset_from_relay_to_system_para`, so now we can extend
this test with more _governance-like_ senarios.
- Renamed to
`send_transact_as_superuser_from_relay_to_system_para_works`.

**Remove `send_transact_native_from_relay_to_system_para_fails` test**
- This test and/or description is kind of misleading, because system
paras support Native from relay chain by `RelayChainAsNative` with
correct xcm origin.
- It tested only sending on relay chain which should go directly to the
relay chain unit-tests (does not even need to be in xcm emulator level).

## Future directions

Check restructure parachains integration tests
[issue](https://github.com/paritytech/polkadot-sdk/issues/1389) and [PR
with more TODOs](https://github.com/paritytech/polkadot-sdk/pull/1693

).

      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.

      Init System Parachain storage versions and add migration check jobs to CI (#1344) · db3fd687
      Liam Aharon authored 
      Makes SPs first class citizens along with the relay chains in the
context of our CI runtime upgrade checks.

## Code changes

- Sets missing current storage version in `uniques` pallet
- Adds multisig V1 migration to run where it was missing
- Removes executed migration whos pre/post hooks were failing from
collectives runtime
- Initializes storage versions for SP pallets added after genesis
- Originally I was going to wait for
https://github.com/paritytech/polkadot-sdk/pull/1297 to be merged so
this wouldn't need to be done manually, but it doesn't seem like it'll
be merged any time soon so I've decided to set them manually to unblock
this

## CI changes

- Removed dependency of `westend` runtime upgrades being complete prior
to other ones running. I assume it is supposed to cache the
`try-runtime` build for a performance benefit, but it seems it wasn't
working. Maybe someone from the CI team can look into this or explain
why it needs to be there?

- Adds check-runtime-migration jobs for Parity asset-hubs, bridge-hubs
and contract chains

- Updated VARIABLES to accomodate the `kusama-runtime` package being
renamed to `staging-kusama-runtime` in
https://github.com/paritytech/polkadot-sdk/pull/1241

- Added `EXTRA_ARGS` variable to `check-runtime-migration`, and set
`--no-weight-warnings` to the relay chain runtime upgrade checks (relay
chains don't have weight restrictions).

      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.
