      Contracts: use compiled rust tests (#2347) · 2135fa87
      PG Herveou authored 
      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

      Remove deprecated `AllPalletsXY` types.

They have been deprecated for nearly 1.5 years now, I think its fine to
remove them.
If anyone feels like we should first put a date on the deprecation as
stated in the deprecation guideline, feel free to speak up. To me it
looks like this has been forgotten and can be directly removed.

      Rework the event system of `sc-network` (#1370) · e71c484d
      Aaro Altonen authored 
      This commit introduces a new concept called `NotificationService` which
allows Polkadot protocols to communicate with the underlying
notification protocol implementation directly, without routing events
through `NetworkWorker`. This implies that each protocol has its own
service which it uses to communicate with remote peers and that each
`NotificationService` is unique with respect to the underlying
notification protocol, meaning `NotificationService` for the transaction
protocol can only be used to send and receive transaction-related
notifications.

The `NotificationService` concept introduces two additional benefits:
  * allow protocols to start using custom handshakes
  * allow protocols to accept/reject inbound peers

Previously the validation of inbound connections was solely the
responsibility of `ProtocolController`. This caused issues with light
peers and `SyncingEngine` as `ProtocolController` would accept more
peers than `SyncingEngine` could accept which caused peers to have
differing views of their own states. `SyncingEngine` would reject excess
peers but these rejections were not properly communicated to those peers
causing them to assume that they were accepted.

With `NotificationService`, the local handshake is not sent to remote
peer if peer is rejected which allows it to detect that it was rejected.

This commit also deprecates the use of `NetworkEventStream` for all
notification-related events and going forward only DHT events are
provided through `NetworkEventStream`. If protocols wish to follow each
other's events, they must introduce additional abtractions, as is done
for GRANDPA and transactions protocols by following the syncing protocol
through `SyncEventStream`.

      Pools: Add ability to configure commission claiming permissions (#2474) · 75062717
      Ross Bulat authored 
      Addresses #409.

This request has been raised by multiple community members - the ability
for the nomination pool root role to configure permissionless commission
claiming:

> Would it be possible to have a claim_commission_other extrinsic for
claiming commission of nomination pools permissionless?

This PR does not quite introduce this additional call, but amends
`do_claim_commission` to check a new `claim_permission` field in the
`Commission` struct, configured by an enum:

```
enum CommissionClaimPermission {
   Permissionless,
   Account(AccountId),
}
```
This can be optionally set in a bonded pool's
`commission.claim_permission` field:

```
struct BondedPool {
   commission: {
      <snip>
      claim_permission: Option<CommissionClaimPermission<T::AccountId>>,
   },
   <snip>
}
```

This is a new field and requires a migration to add it to existing
pools. This will be `None` on pool creation, falling back to the `root`
role having sole access to claim commission if it is not set; this is
the behaviour as it is today. Once set, the field _can_ be set to `None`
again.

#### Changes
- [x] Add `commision.claim_permission` field.
- [x] Add `can_claim_commission` and amend `do_claim_commission`.
- [x] Add `set_commission_claim_permission` call.
- [x] Test to cover new configs and call.
- [x] Add and amend benchmarks.
- [x] Generate new weights + slot into call
`set_commission_claim_permission`.
- [x] Add migration to introduce `commission.claim_permission`, bump
storage version.
- [x] Update Westend weights.
- [x] Migration working.

The `SkipCheckifFeeless::IDENTIFIER` became transparent (ie was whatever

too, so that libraries that use said info to decode the data (ie subxt)
can behave identically whether or not the `SkipCheckifFeeless` wrapper
is used or not.

      Identity Deposits Relay to Parachain Migration (#1814) · c79b234b
      joe petrowski authored 
      The goal of this PR is to migrate Identity deposits from the Relay Chain
to a system parachain.

The problem I want to solve is that `IdentityOf` and `SubsOf` both store
an amount that's held in reserve as a storage deposit. When migrating to
a parachain, we can take a snapshot of the actual `IdentityInfo` and
sub-account mappings, but should migrate (off chain) the `deposit`s to
zero, since the chain (and by extension, accounts) won't have any funds
at genesis.

The good news is that we expect parachain deposits to be significantly
lower (possibly 100x) on the parachain. That is, a deposit of 21 DOT on
the Relay Chain would need 0.21 DOT on a parachain. This PR proposes to
migrate the deposits in the following way:

1. Introduces a new pallet with two extrinsics: 
- `reap_identity`: Has a configurable `ReapOrigin`, which would be set
to `EnsureSigned` on the Relay Chain (i.e. callable by anyone) and
`EnsureRoot` on the parachain (we don't want identities reaped from
there).
- `poke_deposit`: Checks what deposit the pallet holds (at genesis,
zero) and attempts to update the amount based on the calculated deposit
for storage data.
2. `reap_identity` clears all storage data for a `target` account and
unreserves their deposit.
3. A `ReapIdentityHandler` teleports the necessary DOT to the parachain
and calls `poke_deposit`. Since the parachain deposit is much lower, and
was just unreserved, we know we have enough.

One awkwardness I ran into was that the XCMv3 instruction set does not
provide a way for the system to teleport assets without a fee being
deducted on reception. Users shouldn't have to pay a fee for the system
to migrate their info to a more efficient location. So I wrote my own
program and did the `InitiateTeleport` accounting on my own to send a
program with `UnpaidExecution`. Have discussed an
`InitiateUnpaidTeleport` instruction with @franciscoaguirre . Obviously
any chain executing this would have to pass a `Barrier` for free
execution.

- [x] Confirm People Chain ParaId
- [x] Confirm People Chain deposit rates (determined in
https://github.com/paritytech/polkadot-sdk/pull/2281

      Adds syntax for marking calls feeless (#1926) · 60c77a2e
      gupnik authored 
      Fixes https://github.com/paritytech/polkadot-sdk/issues/1725



This PR adds the following changes:
1. An attribute `pallet::feeless_if` that can be optionally attached to
a call like so:
```rust
#[pallet::feeless_if(|_origin: &OriginFor<T>, something: &u32| -> bool {
	*something == 0
})]
pub fn do_something(origin: OriginFor<T>, something: u32) -> DispatchResult {
     ....
}
```
The closure passed accepts references to arguments as specified in the
call fn. It returns a boolean that denotes the conditions required for
this call to be "feeless".

2. A signed extension `SkipCheckIfFeeless<T: SignedExtension>` that
wraps a transaction payment processor such as
`pallet_transaction_payment::ChargeTransactionPayment`. It checks for
all calls annotated with `pallet::feeless_if` to see if the conditions
are met. If so, the wrapped signed extension is not called, essentially
making the call feeless.

In order to use this, you can simply replace your existing signed
extension that manages transaction payment like so:
```diff
- pallet_transaction_payment::ChargeTransactionPayment<Runtime>,
+ pallet_skip_feeless_payment::SkipCheckIfFeeless<
+	Runtime,
+	pallet_transaction_payment::ChargeTransactionPayment<Runtime>,
+ >,
```

      Initialise on-chain `StorageVersion` for pallets added after genesis (#1297) · c4211b65
      Liam Aharon authored 
      Original PR https://github.com/paritytech/substrate/pull/14641

---

Closes https://github.com/paritytech/polkadot-sdk/issues/109



### Problem
Quoting from the above issue:

> When adding a pallet to chain after genesis we currently don't set the
StorageVersion. So, when calling on_chain_storage_version it returns 0
while the pallet is maybe already at storage version 9 when it was added
to the chain. This could lead to issues when running migrations.

### Solution

- Create a new trait `BeforeAllRuntimeMigrations` with a single method
`fn before_all_runtime_migrations() -> Weight` trait with a noop default
implementation
- Modify `Executive` to call
`BeforeAllRuntimeMigrations::before_all_runtime_migrations` for all
pallets before running any other hooks
- Implement `BeforeAllRuntimeMigrations` in the pallet proc macro to
initialize the on-chain version to the current pallet version if the
pallet has no storage set (indicating it has been recently added to the
runtime and needs to have its version initialised).

### Other changes in this PR

- Abstracted repeated boilerplate to access the `pallet_name` in the
pallet expand proc macro.

### FAQ

#### Why create a new hook instead of adding this logic to the pallet
`pre_upgrade`?

`Executive` currently runs `COnRuntimeUpgrade` (custom migrations)
before `AllPalletsWithSystem` migrations. We need versions to be
initialized before the `COnRuntimeUpgrade` migrations are run, because
`COnRuntimeUpgrade` migrations may use the on-chain version for critical
logic. e.g. `VersionedRuntimeUpgrade` uses it to decide whether or not
to execute.

We cannot reorder `COnRuntimeUpgrade` and `AllPalletsWithSystem` so
`AllPalletsWithSystem` runs first, because `AllPalletsWithSystem` have
some logic in their `post_upgrade` hooks to verify that the on-chain
version and current pallet version match. A common use case of
`COnRuntimeUpgrade` migrations is to perform a migration which will
result in the versions matching, so if they were reordered these
`post_upgrade` checks would fail.

#### Why init the on-chain version for pallets without a current storage
version?

We must init the on-chain version for pallets even if they don't have a
defined storage version so if there is a future version bump, the
on-chain version is not automatically set to that new version without a
proper migration.

e.g. bad scenario:

1. A pallet with no 'current version' is added to the runtime
2. Later, the pallet is upgraded with the 'current version' getting set
to 1 and a migration is added to Executive Migrations to migrate the
storage from 0 to 1
    a. Runtime upgrade occurs
    b. `before_all` hook initializes the on-chain version to 1
c. `on_runtime_upgrade` of the migration executes, and sees the on-chain
version is already 1 therefore think storage is already migrated and
does not execute the storage migration
Now, on-chain version is 1 but storage is still at version 0.

By always initializing the on-chain version when the pallet is added to
the runtime we avoid that scenario.
