Many clippy lints usually enforced by `-Dcomplexity` and `-Dcorrectness`
are not caught by CI as they are gated by `features`, like
`runtime-benchmarks`, while the clippy CI job runs with only the default
features for all targets.
This PR also adds a CI step to run clippy with `--all-features` to
ensure the code quality is maintained behind feature gates from now on.
To improve local development, clippy lints are downgraded to warnings,
but they still will result in an error at CI due to the `-Dwarnings`
rustflag.

Adds the `authorize_upgrade` -> `enact_authorized_upgrade` pattern to
`frame-system`. This will be useful for upgrading bridged chains that
are under the governance of Polkadot without passing entire runtime Wasm
blobs over a bridge.
Notes:
- Changed `enact_authorized_upgrade` to `apply_authorized_upgrade`.
Personal opinion, "apply" more accurately expresses what it's doing. Can
change back if outvoted.
- Remove `check_version` in favor of two extrinsics, so as to make
_checked_ the default.
- Left calls in `parachain-system` and marked as deprecated to prevent
breaking the API. They just call into the `frame-system` functions.
- Updated `frame-system` benchmarks to v2 syntax.

Decoupling Pallet from the Concept of Native Currency
Currently, the pallet is intrinsically linked with the concept of native
currency, requiring users to provide implementations of the
`fungible::*` and `fungibles::*` traits to interact with native and non
native assets. This incapsulates some non-related to the pallet
complexity and makes it less adaptable in contexts where the native
currency concept is absent.
With this PR, the dependence on `fungible::*` for liquidity-supplying
assets has been removed. Instead, the native and non-native currencies'
handling is now overseen by a single type that implements the
`fungibles::*` traits. To simplify this integration, types have been
introduced to facilitate the creation of a union between `fungible::*`
and `fungibles::*` implementations, producing a unified `fungibles::*`
type.
One of the reasons driving these changes is the ambition to create a
more user-friendly API for the `SwapCredit` implementation. Given that
it interacts with two distinct credit types from `fungible` and
`fungibles`, a unified type was introduced. Clients now manage potential
conversion failures for those credit types. In certain contexts, it's
vital to guarantee that operations are fail-safe, like in this impl -
[PR](https://github.com/paritytech/polkadot-sdk/pull/1845), place in
[code](https://github.com/paritytech/polkadot-sdk/blob/20b85a5fada8f55c98ba831964f5866ffeadf4da/cumulus/primitives/utility/src/lib.rs#L429).
Additional Updates:
- abstracted the pool ID and its account derivation logic via trait
bounds, along with common implementation offerings;
- removed `inc_providers` on a pool creation for the pool account;
- benchmarks:
-- swap complexity is N, not const;
-- removed `From<u128> + Into<u128>` bound from `T::Balance`;
-- removed swap/liquidity/.. amount constants, resolve them dynamically
based on pallet configuration;
-- migrated to v2 API;
- `OnUnbalanced` handler for the pool creation fee, replacing direct
transfers to a specified account ID;
- renamed `MultiAssetId` to `AssetKind` aligning with naming across
frame crates;

<h2>0.4.30</h2>
<p>In this release, we have decided to swap out the
<code>chrono::Duration</code> type (which has been a re-export of time
0.1 <code>Duration</code> type) with our own definition, which exposes a
strict superset of the <code>time::Duration</code> API. This helps avoid
warnings about the [CVE-2020-26235] and [RUSTSEC-2020-0071] advisories
for downstream users and allows us to improve the <code>Duration</code>
API going forward.</p>

Addresses #1271
Introduces a swap implementation that allows the exchange of a credit
(aka Negative Imbalance) of one asset for a credit of another asset.
This is particularly useful when a credit swap is required but may not
have sufficient value to meet the ED constraint, hence cannot be
deposited to temp account before. An example use case is when XCM fees
are paid using an asset held in the XCM executor registry and has to be
swapped for native currency.
Additional Updates:
- encapsulates the existing `Swap` trait impl within a transactional
context, since partial storage mutation is possible when an error
occurs;
- supplied `Currency` and `Assets` impls must be implemented over the
same `Balance` type, the `AssetBalance` generic type is dropped. This
helps to avoid numerous type conversion and overflow cases. If those
types are different it should be handled outside of the pallet;
- `Box` asset kind on a pallet level, unbox on a runtime level - here
[why](https://substrate.stackexchange.com/questions/10039/boxed-argument-of-a-dispatchable/10103#10103);
- `path` uses `Vec` now, instead of `BoundedVec` since it is never used
in PoV;
- removes the `Transfer` event due to it's redundancy with the events
emitted by `fungible/s` implementations;
- modifies the `SwapExecuted` event type;

When we call the `set_accept_ownership` method, we increase the number
of account consumers, but then we don't decrease it on collection
transfer, which leads to the wrong consumers number an account has.

more than 20 commits. PR fixes this for `node-bench-regression-guard`

A small PR to publicly expose the `pallet_uniques` state that is not
accessible through the nonfungibles implementation.
Currently, this state is unreachable from chain extensions.
closes https://github.com/paritytech-secops/srlabs_findings/issues/78.
Removes `BetterUnsignedThreshold` from pallet EPM. This will essentially
mean any solution submitted by the validator that is strictly better
than the current queued solution would be accepted.
The reason for having these thresholds is to limit number of solutions
submitted on-chain. However for unsigned submissions, the number of
solutions that could be submitted on average is limited even without
thresholding (calculation shown in the corresponding issue).
Remove old version for `cli_args`, since this was fixed in the latest
version of zombienet and the `latest` version of polkadot introduce the
new flag `--insecure-validator-i-know-what-i-do`.
Fix jobs like

Thx!
Fixes #https://github.com/paritytech/polkadot-sdk/issues/2699
Modifying `expect_validator_set()` in order to be able to walk back
until block 0. The chain state at block 0 is available even if we use
`--sync fast` or `--sync warp`. This way we can retrieve the initial
authority set even when BEEFY genesis is 1 and there is no authority
change entry in the headers log.

`pallet_bridge_parachains::set_operating_mode` and
`pallet_bridge_messages::set_operating_mode`.

`atty` is unmaintaned. See the advisory
https://github.com/advisories/GHSA-g98v-hv3f-hcfr
I picked is-terminal because rustix is already in-tree, so doesn't
increase the dependency footprint, and I am not sure if we can rely on
`IsTerminal` from the std because I am not sure what our MSRV.
This PR adds [Rococo
People](https://github.com/paritytech/polkadot-sdk/pull/2281) <> [Rococo
Bulletin](https://github.com/zdave-parity/polkadot-bulletin-chain) to
the Rococo Bridge Hub code. There's a couple of things left to do here:
- [x] add remaining tests - it'd need some refactoring in the
`bridge-hub-test-utils` - will do in a separate PR;
- [x] actually run benchmarks for new messaging pallet (do we have bot
nowadays?).
The reason why I'm opening it before this ^^^ is ready, is that I'd like
to hear others opinion on how to deal with hacks with that bridge.
Initially I was assuming that Rococo Bulletin will be the 1:1 copy of
the Polkadot Bulletin (to avoid maintaining multiple
runtimes/releases/...), so you can see many `PolkadotBulletin` mentions
in this PR, even though we are going to bridge with the parallel chain
(`RococoBulletin`). That's because e.g. pallet names from
`construct_runtime` are affecting runtime storage keys and bridges are
using runtime storage proofs => it is important to use names that the
Bulletin chain expects.
But in the end, this hack won't work - we can't use Polkadot Bulletin
runtime to bridge with Rococo Bridge Hub, because Polkadot Bulletin
expects Polkadot Bridge hub to use `1002` parachain id and Rococo Bridge
Hub seats on the `1013`. This also affects storage keys using in
bridging, so I had to add the [`rococo`
feature](https://github.com/svyatonik/polkadot-bulletin-chain/blob/add-bridge-pallets/runtime/Cargo.toml#L198)
to the Bulletin chain. So now we can actually alter its runtime and
adapt it for Rococo.
So the question here is - what's better for us here
- to leave everything as is (seems hacky and non-trivial);
- change Bulletin chain runtime when `rococo` feature is used - e.g. use
proper names there (`WithPolkadotGrandpa` -> `WithRococoGrandpa`, ...)
- add another set of pallets to the Bulletin chain runtime to bridge
with Rococo and never use them in production. Similar to hack that we
had in Rococo/Wococo
cc @acatangiu @bkontur @serban300
also cc @joepetrowski as the main "client" of this bridge
---
A couple words on how this bridge is different from the Rococo <>
Westend bridge:
- it is a bridge with a chain that uses GRANDPA finality, not the
parachain finality (hence the tests needs to be changed);
- it is a fee-free bridge. So
`AllowExplicitUnpaidExecutionFrom<Equals<SiblingPeople>>` + we are not
paying any rewards to relayers (apart from compensating transaction
costs).

In the move from the old `Currency` traits to the new `fungible/s`
family of traits, we already had the `FungiblesAdapter` and
`NonFungiblesAdapter` for multiple fungible and non fungible assets
respectively. However, for handling only one fungible asset, we were
missing a `FungibleAdapter`, and so used the old `CurrencyAdapter`
instead. This PR aims to fill in that gap, and provide the new adapter
for more updated examples.
I marked the old `CurrencyAdapter` as deprecated as part of this PR, and
I'll change it to the new `FungibleAdapter` in a following PR.
The two stages are separated so as to not bloat this PR with some name
fixes in tests.

This tool makes it easy to run parachain consensus stress/performance
testing on your development machine or in CI.
## Motivation
The parachain consensus node implementation spans across many modules
which we call subsystems. Each subsystem is responsible for a small part
of logic of the parachain consensus pipeline, but in general the most
load and performance issues are localized in just a few core subsystems
like `availability-recovery`, `approval-voting` or
`dispute-coordinator`. In the absence of such a tool, we would run large
test nets to load/stress test these parts of the system. Setting up and
making sense of the amount of data produced by such a large test is very
expensive, hard to orchestrate and is a huge development time sink.
## PR contents
- CLI tool
- Data Availability Read test
- reusable mockups and components needed so far
- Documentation on how to get started
### Data Availability Read test
An overseer is built with using a real `availability-recovery` susbsytem
instance while dependent subsystems like `av-store`, `network-bridge`
and `runtime-api` are mocked. The network bridge will emulate all the
network peers and their answering to requests.
The test is going to be run for a number of blocks. For each block it
will generate send a “RecoverAvailableData” request for an arbitrary
number of candidates. We wait for the subsystem to respond to all
requests before moving to the next block.
At the same time we collect the usual subsystem metrics and task CPU
metrics and show some nice progress reports while running.
### Here is how the CLI looks like:
