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

This small PR removes an unnecessary trait bound to the `AuxStore` trait
from the Parachain template's `rpc.rs` file.
With that bound removed, the entire dependency on `sc-client-api` can
also be removed.

Since the Polkadot and Kusama runtimes are no longer in the repo, the
relevant systems parachains runtimes also need to be removed. More
context [here](https://github.com/paritytech/polkadot-sdk/issues/603)
and [here](https://github.com/paritytech/polkadot-sdk/pull/1731).
Removes the following:
- `asset-hub-kusama` and `asset-hub-polkadot`
- `bridge-hub-kusama` and `bridge-hub-polkadot`
- `collectives-polkadot`
- `glutton-kusama`
Partially solves #603 and adds to #1731.
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`.

The test was a bit flaky on CI.
There was a race condition in the pov-recovery system. If the timing is
bad, it can happen that a block waits for a parent that is already
queued for import. The check if a block has children waiting happens
when we insert into the import queue. So we need to do an additional
check once we receive the import notification for the parent block.
Second issue is that `alice` was missing `--in-peers 0` and `--out-peers
0`, so alice was sometimes still fetching block via sync and the
assertion on the logs in zombienet would fail.
There is another potential issue that I saw once locally. We have a
failing pov-recovery queue that fails from time to time to check that
the retry mechanism does what it should. We now make sure that the same
candidate is never failed twice, so the tests become more predictable.
Currently the polkadot node will backoff from block authoring if
finality starts lagging. This PR disables this mechanism on production
networks (polkadot and kusama) and adds a flags to optionally force
enabling it.
## Overview
This PR aligns the `spec_version` formatting to the [recent
changes](https://github.com/polkadot-fellows/runtimes/pull/26/files#diff-efa4caeb17487ecb13d8f5eb7863c3241d84afa2e73fbf25909a2ca89df0f362R142)
made for the Polkadot/Kusama runtimes.
It also backports the latest version `v1.4.0` bumps as `1_004_000`.
## Details
During the switch from `v0.9` to `v1.x`, the format of the
`spec_version` was modified from: `(M)m_ppp` for a runtime considered on
version `M.m.pp`. For instance `0.9.42` had a `spec_version` of `9420`.
With the transition to `v1.x`, the format was changed to a bigger number
(still `u32`) formatted as `MM_mm_ppp` where `1.2.3` would be stored as
`01_02_003`.
This PR aligns the format with that has been introduced in the
fellowship repo: `MMM_mmm_ppp`.

The last issue blocking the removal of the Polkadot and Kusama system
parachains from the repo in #1737 is the dependency on the runtime code
through the RuntimeApi in `polkadot-parachain`.
This PR introduces two fake runtimes to satisfy the build requirements
and changes the `new_partial` function to make it not be generic over
the runtimes.
The reason for the second runtime is the different Aura keys used in
Polkadot Asset Hub, as the impl for AuraApi depends on this type.
If this changes the `RuntimeApi` generic could be removed completely
from all functions in `services.rs` and and generic type parameters in
`services.rs` and specified as a concrete type to TFullClient`.

I noticed that this test broke at some point. The parachain nodes should
only acquire their blocks from the relay chain. But they were connecting
to their peers and started fetching blocks from there.
In this test I now take additional measures so we check that each nodes
really uses pov-recovery to get the blocks.
On extrinsics/call, ensure local XCM execution is complete/successful.
Otherwise, fail the extrinsic so that state changes don't get committed
to the db.
Added regression tests that fail without the fix.

Add the possibility to inject additional key-values in the
sproof-builder that generates the relay root that gets stored in
parachain-system.
Rationale: pallets that verify additional storage items (not those
verified by parachain-system) from the relay should be able to proof
against the relay root that gets stored in parachain-system. This PR
allows to create provide additional nibles that can later be used for
verifiability in other pallets
This is follow-up for:
https://github.com/paritytech/polkadot-sdk/pull/2001
Block import queue for `test-parachain` (`cumulus-test-service`) shall
use delayed best block feature.
This should fixed broken zombienet tests.
This PR adds the `delayed_best_block` flag to `ParachainBlockImport`. If
not set, the `params.fork_choice` is not updated (to
`ForkChoiceStrategy::Custom`) during the block import.
When `delayed_best_block` is set to `false` all parachain blocks on the
[longest
fork](https://github.com/paritytech/polkadot-sdk/blob/552be4800d9e4b480f79a300fc531783e04be099/substrate/client/service/src/client/client.rs#L708-L709)
will be notified as the best block, allowing transaction pool to be
updated with every imported block.
Otherwise imported blocks will not be notified as best blocks
(`fork_choice=ForkChoiceStrategy::Custom(false)`), and transaction pool
would be updated only with best block received from relay-chain.
Improvement for: #1202

Westend Collectives migration CI check can be fixed once we have
https://github.com/paritytech/try-runtime-cli/pull/58, will open another
PR once it is available.
- [x] Remove deprecated `DmpQueue` pallet from Rococo Contracts, the
migration is complete
- [x] Fix Asset Hub Rococo storage versions
- [x] Add migration check CI for Asset Hub Rococo and Westend Bridge Hub
The `--relay-chain-rpc-urls` CLI flag has been available for a while
now. We have collators with this running and parachain teams are also
using it. It should be fine now to remove the experimental status.
This PR fixes two things:
- relax `force_default_xcm_version` for testnet system parachains (e.g.
BridgeHubWestend has now 2 and there is no way to change it to 3, so we
need to call `force_xcm_version(3)` for every parachain that it is
connected to, because we send XCMv3 messages)
- add `Storage` item to `PolkadotXcm` pallet definition (now we cannot
see storage items for `pallet_xcm` in PJS)
## TODO
- [ ] when merged open PR to `polkadot-fellows/runtimes` repo
Refunding surplus happens anyway on xcm_executor::post_process(),
automatically refunding surplus to original_origin at the end of
execution. Since SovereignPaidRemoteExporter doesn't ClearOrigin, it can
simply rely on the automatic mechanism.
Furthermore, RefundSurplus instruction refunds _surplus_. Surplus exists
only as a result of Transact, SetErrorHandler or SetAppendix
instructions, none of which being part of the
SovereignPaidRemoteExporter XCM program. So surplus is always zero here
anyway.
Add collectives and glutton parachain westend runtimes to prepare for
#1737.
The removal of system parachain native runtimes #1737 is blocked until
chainspecs and runtime APIs can be dealt with cleanly (merge of #1256
and follow up PRs).
In the meantime, these additions are ready to be merged to `master`, so
I have separated them out into this PR.
Also marked `bridge-hub-westend` as unimplemented in line with [this
issue](https://github.com/paritytech/parity-bridges-common/issues/2602).
TODO
- [x] add to `command-bot` benchmarks
- [x] add to `command-bot-scripts` benchmarks
- [x] generate weights

Adds a `NodeFeatures` bitfield value to the runtime `HostConfiguration`,
with the purpose of coordinating the enabling of node-side features,
such as: https://github.com/paritytech/polkadot-sdk/issues/628 and
https://github.com/paritytech/polkadot-sdk/issues/598.
These are features that require all validators enable them at the same
time, assuming all/most nodes have upgraded their node versions.
This PR doesn't add any feature yet. These are coming in future PRs.
Also adds a runtime API for querying the state of the client features
and an extrinsic for setting/unsetting a feature by its index in the bitfield.
Note: originally part of:
https://github.com/paritytech/polkadot-sdk/pull/1644, but posted as
standalone to be reused by other PRs until the initial PR is merged

This PR adds the ability to bid for collator slots even after the max
number of collators have already registered. This eliminates the first
come, first served mechanism that was in place before.
Key changes:
- added `update_bond` extrinsic to allow registered candidates to adjust
their bonds in order to dynamically control their bids
- added `take_candidate_slot` extrinsic to try to replace an already
existing candidate by bidding more than them
- candidates are now kept in a sorted list in the pallet storage, where
the top `DesiredCandidates` out of `MaxCandidates` candidates in the
list will be selected by the session pallet as collators
- if the candidacy bond is increased through a `set_candidacy_bond`
call, candidates which don't meet the new bond requirements are kicked

Collators were previously reencoding the available data and checking the
erasure root.
Replace that with just checking the PoV hash, which consumes much less
CPU and takes less time.
We also don't need to check the `PersistedValidationData` hash, as
collators don't use it.
Reason:
https://github.com/paritytech/polkadot-sdk/issues/575#issuecomment-1806572230
After systematic chunks recovery is merged, collators will no longer do
any reed-solomon encoding/decoding, which has proven to be a great CPU
consumer.

## Motivation
`pallet-xcm` is the main user-facing interface for XCM functionality,
including assets manipulation functions like `teleportAssets()` and
`reserve_transfer_assets()` calls.
While `teleportAsset()` works both ways, `reserve_transfer_assets()`
works only for sending reserve-based assets to a remote destination and
beneficiary when the reserve is the _local chain_.
## Solution
This PR enhances `pallet_xcm::(limited_)reserve_withdraw_assets` to
support transfers when reserves are other chains.
This will allow complete, **bi-directional** reserve-based asset
transfers user stories using `pallet-xcm`.
Enables following scenarios:
- transferring assets with local reserve (was previously supported iff
asset used as fee also had local reserve - now it works in all cases),
- transferring assets with reserve on destination,
- transferring assets with reserve on remote/third-party chain (iff
assets and fees have same remote reserve),
- transferring assets with reserve different than the reserve of the
asset to be used as fees - meaning can be used to transfer random asset
with local/dest reserve while using DOT for fees on all involved chains,
even if DOT local/dest reserve doesn't match asset reserve,
- transferring assets with any type of local/dest reserve while using
fees which can be teleported between involved chains.
All of the above is done by pallet inner logic without the user having
to specify which scenario/reserves/teleports/etc. The correct scenario
and corresponding XCM programs are identified, and respectively, built
automatically based on runtime configuration of trusted teleporters and
trusted reserves.
#### Current limitations:
- while `fees` and "non-fee" `assets` CAN have different reserves (or
fees CAN be teleported), the remaining "non-fee" `assets` CANNOT, among
themselves, have different reserve locations (this is also implicitly
enforced by `MAX_ASSETS_FOR_TRANSFER=2`, but this can be safely
increased in the future).
- `fees` and "non-fee" `assets` CANNOT have **different remote**
reserves (this could also be supported in the future, but adds even more
complexity while possibly not being worth it - we'll see what the future
holds).

We are introducing a new set of `XcmController` traits (final name yet
to be determined).
These traits are implemented by `pallet-xcm` and allows other pallets,
such as `pallet_contracts`, to rely on these traits instead of tight
coupling them to `pallet-xcm`.
Using only the existing Xcm traits would mean duplicating the logic from
`pallet-xcm` in these other pallets, which we aim to avoid. Our
objective is to ensure that when these APIs are called from
`pallet-contracts`, they produce the exact same outcomes as if called
directly from `pallet-xcm`.
The other benefits is that we can also expose return values to
`pallet-contracts` instead of just calling `pallet-xcm` dispatchable and
getting a `DispatchResult` back.
See traits integration in this PR
https://github.com/paritytech/polkadot-sdk/pull/1248, where the traits
are used as follow to define and implement `pallet-contracts` Config.
```rs
// Contracts config:
pub trait Config: frame_system::Config {
// ...
/// A type that exposes XCM APIs, allowing contracts to interact with other parachains, and
/// execute XCM programs.
type Xcm: xcm_executor::traits::Controller<
OriginFor<Self>,
<Self as frame_system::Config>::RuntimeCall,
BlockNumberFor<Self>,
>;
}
// implementation
impl pallet_contracts::Config for Runtime {
// ...
type Xcm = pallet_xcm::Pallet<Self>;
}
