Subject: [PATCH 003/211] sc-executor: Increase maximum instance count (#1856)

Changes the maximum instances count for `wasmtime` to `64`. It also
allows to only pass in maximum `32` for `--max-runtime-instances` as
`256` was way too big. With `64` instances in total and `32` that can be
configured in maximum, there should be enough space to accommodate for
extra instances that are may required to be allocated adhoc.

heading.

# Description

*Please include a summary of the changes and the related issue. Please
also include relevant motivation and context,
including:*

- What does this PR do?

make 'substrate-wasm-builder' manually set 'CARGO_TARGET_DIR' to
'$project_dir/target' while building instead of unset
'CARGO_TARGET_DIR';

- Why are these changes needed?

If you using this in the `build.rs` with following content in your
`~/.cargo/config.toml':

    [build]
    target-dir = "target"

the build process will stuck because of dead lock -- two `cargo build`
on same target directory in the same time.
There is already an attempt to avoid such dead lock by unset the
`CARGO_TARGET_DIR`, but for users with config above in his build
enviroment (like me), this workaround won't work.

- How were these changes implemented and what do they affect?

Instead of unset 'CARGO_TARGET_DIR', we set 'CARGO_TARGET_DIR' to
'$project/target/', which is already assumed to be true by rest of the
code.

*Use [Github semantic

I have built my project with this fix, there's still some warnings with
`build.target-dir` set but the building process won't hang.
I haven't found related issue in this repo. But I did find one issue
[here](https://github.com/substrate-developer-hub/substrate-node-template/issues/116).

Subject: [PATCH 005/211] paras-scheduler: Fix migration to V1 (#1969)

The migration was missing to migrate `AvailabilityCores`. If this isn't
migrated, all parachains in the availability phase would stall until the
next session is started. This pull request fixes this by migrating this
data. Besides that it is doing some cosmetics.

Subject: [PATCH 006/211] Remove `(rococo/westend)-runtime` deps from testnet
 AssetHubs (#1979)

## Problem

This PR addresses the issue with testnet AssetHub builds, which was
discovered during the execution of `bot bench`.

https://gitlab.parity.io/parity/mirrors/polkadot-sdk/-/jobs/4038738
```
     Compiling asset-hub-rococo-runtime-wasm v1.0.0 (/builds/parity/mirrors/polkadot-sdk/target/production/wbuild/asset-hub-rococo-runtime)

  error: could not compile `asset-hub-westend-runtime-wasm` (lib) due to previous error; 1 warning emitted
```

## Solution

- Removed dependencies on `rococo-runtime` and `westend-runtime`
introduced by [this
PR](https://github.com/paritytech/polkadot-sdk/pull/1234/files#diff-a86375df98e04ca3cce1ea35c40257a222e2d5087f5f528ff33307678b78dc2dR534-R550).
- Replaced `<rococo_runtime::Treasury as PalletInfoAccess>::index()`
with `rococo_runtime_constants::TREASURY_PALLET_ID`.
- Added `check_treasury_pallet_id` to the relay runtimes to ensure that
the constant is aligned with the pallet id.
- Added "Rococo Treasury" to the waived locations (that will not be
charged fees in the executor) for `BridgeHubRococo` (to be aligned with
AssetHubs).

Subject: [PATCH 007/211] [testnet] BridgeHubRococo nits (#1972)

This PR does not introduce any functional changes to the existing code,
it merely addresses several minor refactors:
- Moving bridging pallets to separate files.
- Improving the readability and naming of weight files for bridging
pallets and bridging pallet instances.

The reason for this refactor is to facilitate easier plugin integration
for the upcoming bridge between Rococo and Westend.

Subject: [PATCH 008/211] Re-enable Identity on Westend and Rococo (#1901)

Reverts https://github.com/paritytech/polkadot-sdk/pull/1476

The `lock_pallet` / `unlock_pallet` additions in
https://github.com/paritytech/polkadot-sdk/pull/1814 will result in less
downtime for users than using runtime upgrades.

Subject: [PATCH 011/211] Resolve Credit to Account impls of `OnUnbalanced`
 trait (#1876)

Implements the `OnUnbalanced` trait to resolve received credits to the
specified account. Credits that fail to resolve are dropped.

### Motivation
Throughout the codebase, several types implement the trait with the same
behavior. While some currently utilize older currency trait, a migration
to the new fungible/s is anticipated for all. Examples:

Subject: [PATCH 012/211] Update wasm-opt to 0.116 (#1995)

Just keeping wasm-opt up to date.

I don't see anything in the [binaryen
changelog](https://github.com/WebAssembly/binaryen/blob/main/CHANGELOG.md)
that should affect substrate.

This release includes dwarf passes that were accidentally omitted from
previous versions of the wasm-opt crate. I suspect this will not affect
substrate as their omission hasn't been noticed until recently.

Subject: [PATCH 014/211] Ensure correct variant count in
 `Runtime[Hold/Freeze]Reason` (#1900)

closes https://github.com/paritytech/polkadot-sdk/issues/1882

## Breaking Changes

This PR introduces a new item to `pallet_balances::Config`:

```diff
trait Config {
++    type RuntimeFreezeReasons;
}
```

This value is only used to check it against `type MaxFreeze`. A similar
check has been added for `MaxHolds` against `RuntimeHoldReasons`, which
is already given to `pallet_balances`.

In all contexts, you should pass the real `RuntimeFreezeReasons`
generated by `construct_runtime` to `type RuntimeFreezeReasons`. Passing
`()` would also work, but it would imply that the runtime uses no
freezes at all.

Subject: [PATCH 015/211] Make `IdentityInfo` generic in `pallet-identity`
 (#1661)

Fixes #179

# Description

This PR makes the structure containing identity information used in
`pallet-identity` generic through the pallet `Config`. Additionally, the
old structure is now available in a separate module called `simple`
(pending rename) and is compatible with the new interface.

Another change in this PR is that while the `additional` field in
`IdentityInfo` stays for backwards compatibility reasons, the associated
costs are stil present in the pallet through the `additional` function
in the `IdentityInformationProvider` interface. This function is marked
as deprecated as it is only a temporary solution to the backwards
compatibility problem we had. In short, we could have removed the
additional fields in the struct and done a migration, but we chose to
wait and do it off-chain through the genesis of the system parachain.
After we move the identity pallet to the parachain, additional fields
will be migrated into the existing fields and the `additional` key-value
store will be removed. Until that happens, this interface will provide
the necessary information to properly account for the associated costs.

Additionally, this PR fixes an unrelated issue; the `IdentityField` enum
used to represent the fields as bitflags couldn't store more than 8
fields, even though it was marked as `#[repr(u64)]`. This was because of
the `derive` implementation of `TypeInfo`, which assumed `u8` semantics.
The custom implementation of this trait in
https://github.com/paritytech/polkadot-sdk/commit/0105cc0396b7a53d0b290f48b1225847f6d17321
fixes the issue.

Subject: [PATCH 021/211] Improve features dev-ex (#1831)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Adds a config file that allows to run `zepter` without any arguments in
the workspace to address all issues.
A secondary workflow for the CI is provided as `zepter run check`. Both
the formatting and linting are now in one check for efficiancy.

The latest version also detects some more things that `featalign` was
already showing.

Error message [in the
CI](https://gitlab.parity.io/parity/mirrors/polkadot-sdk/-/jobs/3916205)
now looks like this:
```pre
...
crate 'test-parachains' (/Users/vados/Documents/work/polkadot-sdk/polkadot/parachain/test-parachains/Cargo.toml)
  feature 'std'
    must propagate to:
      parity-scale-codec
Found 55 issues (run with --fix to fix).
Error: Command 'lint propagate-feature' failed with exit code 1

Polkadot-SDK uses the Zepter CLI to detect abnormalities in the feature configuration.
It looks like one more more checks failed; please check the console output. You can try to automatically address them by running `zepter`.
Otherwise please ask directly in the Merge Request, GitHub Discussions or on Matrix Chat, thank you.

For more information, see:
  - https://github.com/paritytech/polkadot-sdk/issues/1831
  - https://github.com/ggwpez/zepter
```

TODO:
- [x] Check that CI fails correctly

Subject: [PATCH 023/211] Application Crypto and BEEFY Support for paired
 (ECDSA,BLS) crypto (#1815)

Next step in process of making BEEFY being able to generate both ECDSA
and BLS signature after #1705. It allows BEEFY to use a pair of ECDSA
and BLS key as a AuthorityId.

Subject: [PATCH 025/211] Small optimisation to `--profile dev` wasm builds
 (#1851)

`wasm-builder` was adjusted to default to building wasm blobs in
`release` mode even when cargo is in `debug` because `debug` wasm is too
slow.

A side effect of this was `.compact` and `.compact.compressed` getting
built when the dev is running build in `debug`, adding ~5s to the build
time of every wasm runtime.

I think it's reasonable to assume if the dev is running `debug` build
they want to optimise speed and do not care about the size of the wasm
binary. Compacting a blob has negligible impact on its actual
performance.

In this PR, I adjusted the behavior of the wasm builder so it does not
produce `.compact` or `.compact.compressed` wasm when the user is
running in `debug`. The builder will continue to produce the bloaty wasm
in release mode unless it is overriden with an env var.

As suggested by @koute in review, also refactored the
`maybe_compact_wasm_and_copy_blobs` into multiple funuctions, and
renamed things to better support RISC-V in the future.

---

There is no `T-runtime` label so @KiChjang told me to put `T1-FRAME` :)

Subject: [PATCH 029/211] [testnet] Align testnet system parachain runtimes
 using `RelayTreasuryLocation` and `SystemParachains` in the same way (#2023)

This PR addresses several issues:
- simplify referencing `RelayTreasuryLocation` without needing
additional `RelayTreasury` struct
- fix for referencing `SystemParachains` from parachain with `parents:
1` instead of `parents: 0`
- removed hard-coded constants and fix tests for `asset-hub-rococo`
which was merged to master after
https://github.com/paritytech/polkadot-sdk/pull/1726

Subject: [PATCH 030/211] `polkadot-parachain-primitives` should not depend on
 `frame-support`. (#1897)

This PR does not make any functional changes to the code. Rather, it
restructures the dependency graph.

Before this PR, the crate `polkadot-parachain-primitives` depended
directly on the crate `frame-support`. This is wrong in principal
because a parachain does not necessarily have anything to do with frame.

This dependency was only for the `Weight` type which was just a
re-export from `sp-weights` anyway. So this PR changes the dependency to
be directly on the much lighter `sp-weights`.

Subject: [PATCH 031/211] Expose collection attributes from `Inspect` trait
 (#1914)

# Description

- What does this PR do?

While working with `pallet_nfts` through `nonfungibles_v2` traits
`Inspect, Mutate`, I found out that once you have set the collection
attribute with `<Nfts as Mutate>::set_collection_attribute()`, it's not
possible to read it with `<Nfts as Inspect>::collection_attribute()`
since they use different `namespace` values. When setting the attribute,
`AttributeNamespace::Pallet` is used, while
`AttributeNamespace::CollectionOwner` is used when reading.

more context:
https://github.com/freeverseio/laos/issues/7#issuecomment-1766137370

This PR makes `item` an optional parameter in
`Inspect::system_attribute()`, to be able to read collection attributes.

- Why are these changes needed?

To be able to read collection level attributes when reading attributes
of the collection. It will be possible to read collection attributes by
passing `None` for `item`

- How were these changes implemented and what do they affect?

`NftsApi` is also affected and `NftsApi::system_attribute()` now accepts
optional `item` parameter.

## Breaking change

Because of the change in the `NftsApi::system_attribute()` method's
`item` param, parachains who integrated the `NftsApi` need to update
their API code and frontend integrations accordingly. AssetHubs are
unaffected since the NftsApi wasn't released on those parachains yet.

Subject: [PATCH 033/211] cumulus: fix test runtimes panic (#2039)

the min slot duration should be 0 only if the `experimental` feature is
enabled. otherwise, the runtime will panic on a division by 0.

Subject: [PATCH 036/211] upgrade docify to 0.2.5 (#2052)

Updates `docify` to 0.2.5, which fixes some indentation bugs and adds
the new `#[docify::export_content]` attribute which can be used like
regular `#[docify::export]` but will only export the _underlying
contents_ of the item it is attached to, if applicable (otherwise it
just behaves exactly like `#[docify::export]`).

Release notes here:
https://github.com/sam0x17/docify/releases/tag/v0.2.5

Subject: [PATCH 037/211] feat: FRAME umbrella crate. (#1337)

### Original PR https://github.com/paritytech/substrate/pull/14137

This PR brings in the first version of the "_`frame` umbrella crate_".
This crate is intended to serve two purposes:

1. documentation
2. easier development with frame. Ideally, we want most users to be able
to build a frame-based pallet and runtime using just `frame` (plus
`scale-codec` and `scale-info`).

The crate is not finalized and is not yet intended for external use.
Therefore, the version is set to `0.0.1-dev`, this PR is `silent`, and
the entire crate is hidden behind the `experimental` flag. The main
intention in merging it early on is to be able to iterate on it in the
rest of
[`developer-hub`](https://github.com/paritytech/polkadot-sdk-docs/)
efforts.

The public API of the `frame` crate is at the moment as follows:

```

The road to full stabilization is

- [ ] https://github.com/paritytech/polkadot-sdk/issues/127
- [ ] have a more intentional version bump, as opposed to the current bi
weekly force-major-bump
- [ ] revise the internal API of `frame`, especially what goes into the
`prelude`s.
- [ ] migrate all internal pallets and runtime to use `frame`

-/// The client and the runtime of course need to communicate. This is done through two concepts:
-///
-/// 1. Host functions: a way for the (Wasm) runtime to talk to the client. All host functions are
-///    defined in [`sp-io`]. For example, [`sp-io::storage`] are the set of host functions that
-///    allow the runtime to read and write data to the on-chain state.
-/// 2. Runtime APIs: a way for the client to talk to the Wasm runtime. Runtime APIs are defined
-///    using macros and utilities in [`sp-api`]. For example, [`sp-api::Core`] is the most basic
-///    runtime API that any blockchain must implement in order to be able to (re) execute blocks.
-///
-/// ```mermaid
-/// graph TB
-/// subgraph Substrate
-/// 	direction LR
-/// 	subgraph Client
-/// 	end
-/// 	subgraph Runtime
-/// 	end
-/// 	Client --runtime-api--> Runtime
-/// 	Runtime --host-functions--> Client
-/// end
-/// ```
-///
-/// Finally, let's expand the diagram a bit further and look at the internals of each component:
-///
-/// ```mermaid
-/// graph TB
-/// subgraph Substrate
-/// 	direction LR
-/// 	subgraph Client
-/// 		Database
-/// 		Networking
-/// 		Consensus
-/// 	end
-/// 	subgraph Runtime
-/// 		subgraph FRAME
-/// 			direction LR
-/// 			Governance
-/// 			Currency
-/// 			Staking
-/// 			Identity
-/// 		end
-/// 	end
-/// 	Client --runtime-api--> Runtime
-/// 	Runtime --host-functions--> Client
-/// end
-/// ```
-///
-/// As noted the runtime contains all of the application specific logic of the blockchain. This is
-/// usually written with `FRAME`. The client, on the other hand, contains reusable and generic
-/// components that are not specific to one single blockchain, such as networking, database, and the
-/// consensus engine.

Subject: [PATCH 038/211] make polkadot die graciously (#2056)

While investigating some db migrations that make the node startup fail,
I noticed that the node wasn't exiting and that the log file were
growing exponentially, until my whole system was freezing and that makes
it really hard to actually find why it was failing in the first place.

E.g:
```
 ls -lh /tmp/zombie-01a04c2a2c0265d85f6440cf01c0f44a_-51319-uyggzuD4wEpV/bob.log
 32,6G oct 27 11:16 /tmp/zombie-01a04c2a2c0265d85f6440cf01c0f44a_-51319-uyggzuD4wEpV/bob.log
```

This was happening because the following errors were being printed
continously without the subsystem main loop exiting:

From dispute-coordinator:
```
WARN tokio-runtime-worker parachain::dispute-coordinator: error=Subsystem(Generated(Context("Signal channel is terminated and empty.")))
```

From availability recovery:
```
Erasure task channel closed. Node shutting down ?
```

Subject: [PATCH 040/211] level-monitor: Fix issue with warp syncing (#2053)

When warp syncing a node we import a header of the parachain around the
tip of the chain. This header is currently not imported as finalized
block (should be fixed at some point as well), the parent headers are
not yet present (still being synced) and thus, we run into a panic. Even
if there is a case where a leaf could not be found in the database, this
probably means that the db is broken and it will fail somewhere elese.

Subject: [PATCH 041/211] upgrade to docify 0.2.6 (#2069)

Updates `docify` to 0.2.6, which fixes a bug that was preventing nesting
`#[docify::export]` within sub-items of items that already have
`#[docify::export]` attached to them from working properly.

Release notes here:
https://github.com/sam0x17/docify/releases/tag/v0.2.6

Subject: [PATCH 042/211] Automatically build and attach production and dev
 runtimes to GH releases (#2054)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Closes https://github.com/paritytech/release-engineering/issues/6

Adds a new Github Workflow which on a new release being created, builds
and attaches all runtimes managed in this repository in two flavours:
- `dev-debug-build`: Built with the `try-runtime` feature and has
logging enabled
- `on-chain-release`: Built with the regular old `on-chain-release`
feature

The new Github Workflow could be extended in the future by the
@paritytech/release-engineering team to fully automate the release
process if they choose to, similar to how it is fully automated in the
Fellowship repo
(https://github.com/polkadot-fellows/runtimes/blob/main/.github/workflows/release.yml).

The `on-chain-release` did not exist for parachains, so I added it.

---

Tested on my fork:
- https://github.com/liamaharon/polkadot-sdk/actions/runs/6663773523
- https://github.com/liamaharon/polkadot-sdk/releases/tag/test-6

Subject: [PATCH 043/211] fix(frame-benchmarking-cli): Pass heap_pages param to
 WasmExecutor (#2075)

In https://github.com/paritytech/substrate/pull/13740 the use of the
`heap-pages` param inside the `frame-benchmarking-cli` has been removed.
This results in running out of memory and this PR fixes the heap
allocation strategy for benchmarks wasm executor.

Subject: [PATCH 044/211] Improve Client CLI help readability (#2073)

Currently the CLI `-h/--help` commad output is almost unreadable as (for
some commands) it:
- doesn't provide a short brief of what the command does.
- doesn't separate the options description in smaller paragraphs.
- doesn't use a smart wrap strategy for lines longer than the number of
columns in the terminal.

Follow some pics taken with a 100 cols wide term

## Short help (./node -h)

Subject: [PATCH 045/211] Improve `try-state` developer experience & fix bug
 (#2019)

Making some devex improvements as I audit our chains adherence to
try-state invariants, in preparation for automated try-state checks and
alerting.

Note to reviewer: while you're here, if you have time would be great to
get your eyes on https://github.com/paritytech/polkadot-sdk/pull/1297
also since it touches a similar file and I'd like to avoid merge
conflicts :P

## Devex Improvements

- Changes the log level of logs informing the user that try-state checks
are being run for a pallet from debug to info
- Improves how errors are communicated
- Errors are logged when they are encountered, rather than after
everything has been executed
- Exact pallet the error originated from is included with the error log
  - Clearly see all errors and how many there are, rather than only one
  - Closes #136

### Example of new logs

src="https://github.com/paritytech/polkadot-sdk/assets/16665596/b75588a2-1c64-45df-bbc8-bcb8bf8b0fe0">

### Same but with old logs (run with RUST_LOG=debug)

Notice only informed of one of the errors, and it's unclear which pallet
it originated

## Bug fix

When dry-running migrations and `checks.try_state()` is `true`, only run
`try_state` checks after migrations have been executed. Otherwise,
`try_state` checks that expect state to be in at a HIGHER storage
version than is on-chain could incorrectly fail.

Subject: [PATCH 047/211] contracts migration: remove unnecessary panics
 (#2079)

Runtime migration CI is currently failing
(https://gitlab.parity.io/parity/mirrors/polkadot-sdk/builds/4122083)
for the contracts testnet due to unnecessary panicing in a `pre_upgrade`
hook.

Soon idempotency will be enforced
https://github.com/paritytech/try-runtime-cli/issues/42, in the mean
time we need to manually fix these issues as they arise.

---

also removes backticks from the string in `echo`, which caused a
'command not found' error in ci output

-	/// The issue with this is indeterminacy. If half of validators were on V2 and half were on V1,

+//! Functionality for sandboxing workers by restricting their capabilities by blocking certain
+//! syscalls with seccomp.
+//!
+//! For security we block the following:
+//!
+//! - creation of new sockets - these are unneeded in PVF jobs, and we can safely block them without
+//!   affecting consensus.
+//!
+//! - `io_uring` - allows for networking and needs to be blocked. See below for a discussion on the
+//!   safety of doing this.
+//!
+//! # Safety of blocking io_uring
+//!
+//! `io_uring` is just a way of issuing system calls in an async manner, and there is nothing
+//! stopping wasmtime from legitimately using it. Fortunately, at the moment it does not. Generally,
+//! not many applications use `io_uring` in production yet, because of the numerous kernel CVEs
+//! discovered. It's still under a lot of development. Android outright banned `io_uring` for these
+//! reasons.
+//!
+//! Considering `io_uring`'s status discussed above, and that it very likely would get detected
+//! either by our [static analysis](https://github.com/paritytech/polkadot-sdk/pull/1663) or by
+//! testing, we think it is safe to block it.
+//!
+//! ## Consensus analysis
+//!
+//! If execution hits an edge case code path unique to a given machine, it's already taken a
+//! non-deterministic branch anyway. After all, we just care that the majority of validators reach
+//! the same result and preserve consensus. So worst-case scenario, there's a dispute, and we can
+//! always admit fault and refund the wrong validator. On the other hand, if all validators take the
+//! code path that results in a seccomp violation, then they would all vote against the current
+//! candidate, which is also fine. The violation would get logged (in big scary letters) and
+//! hopefully some validator reports it to us.
+//!
+//! Actually, a worst-worse-case scenario is that 50% of validators vote against, so that there is
+//! no consensus. But so many things would have to go wrong for that to happen:
+//!
+//! 1. An update to `wasmtime` is introduced that uses io_uring (unlikely as io_uring is mainly for
+//!    IO-heavy applications)
+//!
+//! 2. The new syscall is not detected by our static analysis
+//!
+//! 3. It is never triggered in any of our tests
+//!
+//! 4. It then gets triggered on some super edge case in production on 50% of validators causing a
+//!    stall (bad but very unlikely)
+//!
+//! 5. Or, it triggers on only a few validators causing a dispute (more likely but not as bad)
+//!
+//! Considering how many things would have to go wrong here, we believe it's safe to block
+//! `io_uring`.
+//!
+//! # Action on syscall violations
+//!
+//! On syscall violations we currently only log, to make sure this works correctly before enforcing.
+//!
+//! In the future, when a forbidden syscall is attempted we immediately kill the process in order to
+//! prevent the attacker from doing anything else. In execution, this will result in voting against
+//! the candidate.

Subject: [PATCH 054/211] Add test to demonstrate the failure scenario (#1999)

The change adds a test to show the failure scenario that caused #1812 to
be rolled back (more context:
https://github.com/paritytech/polkadot-sdk/issues/493#issuecomment-1772009924)

Summary of the scenario:
1. Node has finished downloading up to block 1000 from the peers, from
the canonical chain.
2. Peers are undergoing re-org around this time. One of the peers has
switched to a non-canonical chain, announces block 1001 from that chain
3. Node downloads 1001 from the peer, and tries to import which would
fail (as we don't have the parent block 1000 from the other chain)

Subject: [PATCH 055/211] check-each-crate: Do not reference crate to check by
 name (#2098)

This pull request changes how `check-each-crate.py` is working. Instead
of passing the name of the crate via `-p`, we now jump into the
directory of the crate and call there `cargo check`. This should fix
issues like https://github.com/paritytech/polkadot-sdk/issues/2013 where
a crate is present twice in the `Cargo.lock`.

Besides that it also changes `core/Cargo.toml` to not always pull in
bandersnatch.

Subject: [PATCH 056/211] Elliptic curves utilities refactory (#2068)

- Usage the new published
[arkworks-extensions](https://github.com/paritytech/arkworks-extensions)
crates.
  Hooks are internally defined to jump into the proper host functions.
- Conditional compilation of each curve (gated by feature with curve
name)
- Separation in smaller host functions sets, divided by curve (fits
nicely with prev point)

Subject: [PATCH 059/211] polkadot: parachains: Fix v9 host configuration
 migration (#2103)

We shouldn't override with their default fields that have been added in
the previous version(v8), because we are going to lose whatever values have
been set.

Note, v8 & v9 seems to have landed at the same time on Rococo, probably
they will land at the same time on westend and other chains, so functionally
doesn't make much difference, but let's have this fixed for people that copy-paste
:D, like me.

Subject: [PATCH 060/211] 1953 defensive testing extrinsic (#1998)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# Description

The `trigger_defensive` call has been added to the `root-testing`
pallet. The idea is to have this pallet running on `Rococo/Westend` and
use it to verify if the runtime monitoring works end-to-end.

To accomplish this, `trigger_defensive` dispatches an event when it is
called.

Closes #1953

# Checklist

- [x] My PR includes a detailed description as outlined in the
"Description" section above
- [ ] My PR follows the [labeling requirements](CONTRIBUTING.md#Process)
of this project (at minimum one label for `T`
  required)
- [ ] I have made corresponding changes to the documentation (if
applicable)
- [ ] I have added tests that prove my fix is effective or that my
feature works (if applicable)

You can remove the "Checklist" section once all have been checked. Thank
you for your contribution!

From 1cd6acdff3618a547dc98d9fd0c7984b5db933ef Mon Sep 17 00:00:00 2001
From: Dmitry Markin <dmitry@markin.tech>
Date: Wed, 1 Nov 2023 15:10:33 +0200
Subject: [PATCH 065/211] Move syncing code from `sc-network-common` to
 `sc-network-sync` (#1912)

This PR moves syncing-related code from `sc-network-common` to
`sc-network-sync`.

Unfortunately, some parts are tightly integrated with networking, so
they were left in `sc-network-common` for now:

1. `SyncMode` in `common/src/sync.rs` (used in `NetworkConfiguration`).
2. `BlockAnnouncesHandshake`, `BlockRequest`, `BlockResponse`, etc. in
`common/src/sync/message.rs` (used in `src/protocol.rs` and
`src/protocol/message.rs`).

More substantial refactoring is needed to decouple syncing and
networking completely, including getting rid of the hardcoded sync
protocol.

## Release notes

Move syncing-related code from `sc-network-common` to `sc-network-sync`.
Delete `ChainSync` trait as it's never used (the only implementation is
accessed directly from `SyncingEngine` and exposes a lot of public
methods that are not part of the trait). Some new trait(s) for syncing
will likely be introduced as part of Sync 2.0 refactoring to represent
syncing strategies.

-//! Contains the state of the chain synchronization process
-//!
-//! At any given point in time, a running node tries as much as possible to be at the head of the
-//! chain. This module handles the logic of which blocks to request from remotes, and processing
-//! responses. It yields blocks to check and potentially move to the database.
-//!
-//! # Usage
-//!
-//! The `ChainSync` struct maintains the state of the block requests. Whenever something happens on
-//! the network, or whenever a block has been successfully verified, call the appropriate method in
-//! order to update it.

Subject: [PATCH 067/211] [NPoS] Paging reward payouts in order to  scale
 rewardable nominators  (#1189)

helps https://github.com/paritytech/polkadot-sdk/issues/439.
closes https://github.com/paritytech/polkadot-sdk/issues/473.

PR link in the older substrate repository:
https://github.com/paritytech/substrate/pull/13498.

# Context
Rewards payout is processed today in a single block and limited to
`MaxNominatorRewardedPerValidator`. This number is currently 512 on both
Kusama and Polkadot.

This PR tries to scale the nominators payout to an unlimited count in a
multi-block fashion. Exposures are stored in pages, with each page
capped to a certain number (`MaxExposurePageSize`). Starting out, this
number would be the same as `MaxNominatorRewardedPerValidator`, but
eventually, this number can be lowered through new runtime upgrades to
limit the rewardeable nominators per dispatched call instruction.

The changes in the PR are backward compatible.

## How payouts would work like after this change
Staking exposes two calls, 1) the existing `payout_stakers` and 2)
`payout_stakers_by_page`.

### payout_stakers
This remains backward compatible with no signature change. If for a
given era a validator has multiple pages, they can call `payout_stakers`
multiple times. The pages are executed in an ascending sequence and the
runtime takes care of preventing double claims.

### payout_stakers_by_page
Very similar to `payout_stakers` but also accepts an extra param
`page_index`. An account can choose to payout rewards only for an
explicitly passed `page_index`.

**Lets look at an example scenario**
Given an active validator on Kusama had 1100 nominators,
`MaxExposurePageSize` set to 512 for Era e. In order to pay out rewards
to all nominators, the caller would need to call `payout_stakers` 3
times.

- `payout_stakers(origin, stash, e)` => will pay the first 512
nominators.
- `payout_stakers(origin, stash, e)` => will pay the second set of 512
nominators.
- `payout_stakers(origin, stash, e)` => will pay the last set of 76
nominators.
...
- `payout_stakers(origin, stash, e)` => calling it the 4th time would
return an error `InvalidPage`.

The above calls can also be replaced by `payout_stakers_by_page` and
passing a `page_index` explicitly.

## Commission note
Validator commission is paid out in chunks across all the pages where
each commission chunk is proportional to the total stake of the current
page. This implies higher the total stake of a page, higher will be the
commission. If all the pages of a validator's single era are paid out,
the sum of commission paid to the validator across all pages should be
equal to what the commission would have been if we had a non-paged
exposure.

### Migration Note
Strictly speaking, we did not need to bump our storage version since
there is no migration of storage in this PR. But it is still useful to
mark a storage upgrade for the following reasons:

- New storage items are introduced in this PR while some older storage
items are deprecated.
- For the next `HistoryDepth` eras, the exposure would be incrementally
migrated to its corresponding paged storage item.
- Runtimes using staking pallet would strictly need to wait at least
`HistoryDepth` eras with current upgraded version (14) for the migration
to complete. At some era `E` such that `E >
era_at_which_V14_gets_into_effect + HistoryDepth`, we will upgrade to
version X which will remove the deprecated storage items.
In other words, it is a strict requirement that E<sub>x</sub> -
E<sub>14</sub> > `HistoryDepth`, where
E<sub>x</sub> = Era at which deprecated storages are removed from
runtime,
E<sub>14</sub> = Era at which runtime is upgraded to version 14.
- For Polkadot and Kusama, there is a [tracker
ticket](https://github.com/paritytech/polkadot-sdk/issues/433) to clean
up the deprecated storage items.

### Storage Changes

#### Added
- ErasStakersOverview
- ClaimedRewards
- ErasStakersPaged

#### Deprecated
The following can be cleaned up after 84 eras which is tracked
[here](https://github.com/paritytech/polkadot-sdk/issues/433).

- ErasStakers.
- ErasStakersClipped.
- StakingLedger.claimed_rewards, renamed to
StakingLedger.legacy_claimed_rewards.

### Config Changes
- Renamed MaxNominatorRewardedPerValidator to MaxExposurePageSize.

### TODO
- [x] Tracker ticket for cleaning up the old code after 84 eras.
- [x] Add companion.
- [x] Redo benchmarks before merge.
- [x] Add Changelog for pallet_staking.
- [x] Pallet should be configurable to enable/disable paged rewards.
- [x] Commission payouts are distributed across pages.
- [x] Review documentation thoroughly.
- [x] Rename `MaxNominatorRewardedPerValidator` ->
`MaxExposurePageSize`.
- [x] NMap for `ErasStakersPaged`.
- [x] Deprecate ErasStakers.
- [x] Integrity tests.

### Followup issues
[Runtime api for deprecated ErasStakers storage
item](https://github.com/paritytech/polkadot-sdk/issues/426)

+title: Supporting paged rewards allowing all nominators to be rewarded
+
+doc:
+  - audience: Validator
+    description: |
+      We used to clip top `MaxNominatorRewardedPerValidator` nominators by stake that are eligible for staking reward.
+      This was done to limit computation cost of paying out rewards. This PR introduces paging to reward payouts,
+      meaning we still clip nominators upto MaxExposurePageSize per page and there could be multiple pages of rewards to
+      be paid out. Validators get commission pro-rata to the amount of reward that is paid out for the page.
+
+    notes:
+      - payout_stakers should be called multiple times, once for each page of nominators.
+      - payout_stakers_by_page can be used to pay out rewards for a specific page.
+      - Some old non-paged era storage items are deprecated, and can be removed in a future upgrade.

+# Changelog
+
+All notable changes and migrations to pallet-staking will be documented in this file.
+
+The format is loosely based
+on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/). We maintain a
+single integer version number for staking pallet to keep track of all storage
+migrations.
+
+## [v14]
+
+### Added
+
+- New item `ErasStakersPaged` that keeps up to `MaxExposurePageSize`
+  individual nominator exposures by era, validator and page.
+- New item `ErasStakersOverview` complementary to `ErasStakersPaged` which keeps
+  state of own and total stake of the validator across pages.
+- New item `ClaimedRewards` to support paged rewards payout.
+
+### Deprecated
+
+- `ErasStakers` and `ErasStakersClipped` is deprecated, will not be used any longer for the exposures of the new era
+  post v14 and can be removed after 84 eras once all the exposures are stale.
+- Field `claimed_rewards` in item `Ledger` is renamed
+  to `legacy_claimed_rewards` and can be removed after 84 eras.

Subject: [PATCH 072/211] Improve FRAME storage docs (#1714)

This is a port (and hopefully a small improvement) of @kianenigma's PR
from the old Substrate repo:
https://github.com/paritytech/substrate/pull/13987. Following #1689 I
moved the documentation of all macros relevant to this PR from
`frame_support_procedural` to `pallet_macros` while including a hint for
RA users.

Question: Again with respect to #1689: Is there a good reason why we
should *not* enhance paths with links to our current rustdocs? For
example, instead of
```rust
/// **Rust-Analyzer users**: See the documentation of the Rust item in
/// `frame_support::pallet_macros::storage`.
```
we could write
```rust
/// **Rust-Analyzer users**: See the documentation of the Rust item in
/// [`frame_support::pallet_macros::storage`](https://paritytech.github.io/polkadot-sdk/master/frame_support/pallet_macros/attr.storage.html).
```
This results in a clickable link like this:
<img width="674" alt="image"
src="https://github.com/paritytech/polkadot-sdk/assets/10713977/c129e622-3942-4eeb-8acf-93ee4efdc99d">
I don't really expect the links to become outdated any time soon, but I
think this would be a great UX improvement over just having paths.

TODOs:
- [ ] Add documentation for `constant_name` macro
- [x] Add proper documentation for different `QueryKinds`, i.e.
`OptionQuery`, `ValueQuery`, `ResultQuery`. One example for each. Custom
`OnEmpty` should be moved to `QueryKinds` trait doc page.
- [ ] Rework `type_value` docs

+	///
+	/// ## Storage Types

+	///
+	/// * [`StorageValue`](crate::storage::types::StorageValue)

+	/// * [`StorageNMap`](crate::storage::types::StorageNMap)
+	/// * [`CountedStorageNMap`](crate::storage::types::CountedStorageNMap)
+	///
+	/// ## Storage Type Usage
+	///
+	/// The following details are relevant to all of the aforementioned storage types.
+	/// Depending on the exact storage type, it may require the following generic parameters:
+	///
+	/// * [`Prefix`](#prefixes) - Used to give the storage item a unique key in the underlying
+	///   storage.
+	/// * `Key` - Type of the keys used to store the values,
+	/// * `Value` - Type of the value being stored,
+	/// * [`Hasher`](#hashers) - Used to ensure the keys of a map are uniformly distributed,
+	/// * [`QueryKind`](#querykind) - Used to configure how to handle queries to the underlying
+	///   storage,
+	/// * `OnEmpty` - Used to handle missing values when querying the underlying storage,
+	/// * `MaxValues` - _not currently used_.
+	///
+	/// Each `Key` type requires its own designated `Hasher` declaration, so that
+	/// [`StorageDoubleMap`](frame_support::storage::types::StorageDoubleMap) needs two of
+	/// each, and [`StorageNMap`](frame_support::storage::types::StorageNMap) needs `N` such
+	/// pairs. Since [`StorageValue`](frame_support::storage::types::StorageValue) only stores
+	/// a single element, no configuration of hashers is needed.
+	///
+	/// ### Syntax
+	///
+	/// Two general syntaxes are supported, as demonstrated below:
+	///
+	/// 1. Named type parameters, e.g., `type Foo<T> = StorageValue<Value = u32>`.
+	/// 2. Positional type parameters, e.g., `type Foo<T> = StorageValue<_, u32>`.
+	///
+	/// In both instances, declaring the generic parameter `<T>` is mandatory. Optionally, it
+	/// can also be explicitly declared as `<T: Config>`. In the compiled code, `T` will
+	/// automatically include the trait bound `Config`.
+	///
+	/// Note that in positional syntax, the first generic type parameter must be `_`.
+	///
+	/// #### Example
+	///
+	/// ```
+	/// #[frame_support::pallet]
+	/// mod pallet {
+	///     # use frame_support::pallet_prelude::*;
+	///     # #[pallet::config]
+	///     # pub trait Config: frame_system::Config {}
+	///     # #[pallet::pallet]
+	///     # pub struct Pallet<T>(_);
+	///     /// Positional syntax, without bounding `T`.
+	///     #[pallet::storage]
+	///     pub type Foo<T> = StorageValue<_, u32>;
+	///
+	///     /// Positional syntax, with bounding `T`.
+	///     #[pallet::storage]
+	///     pub type Bar<T: Config> = StorageValue<_, u32>;
+	///
+	///     /// Named syntax.
+	///     #[pallet::storage]
+	///     pub type Baz<T> = StorageMap<Hasher = Blake2_128Concat, Key = u32, Value = u32>;
+	/// }
+	/// ```
+	///
+	/// ### QueryKind
+	///
+	/// Every storage type mentioned above has a generic type called
+	/// [`QueryKind`](frame_support::storage::types::QueryKindTrait) that determines its
+	/// "query" type. This refers to the kind of value returned when querying the storage, for
+	/// instance, through a `::get()` method.
+	///
+	/// There are three types of queries:
+	///
+	/// 1. [`OptionQuery`](frame_support::storage::types::OptionQuery): The default query type.
+	///    It returns `Some(V)` if the value is present, or `None` if it isn't, where `V` is
+	///    the value type.
+	/// 2. [`ValueQuery`](frame_support::storage::types::ValueQuery): Returns the value itself
+	///    if present; otherwise, it returns `Default::default()`. This behavior can be
+	///    adjusted with the `OnEmpty` generic parameter, which defaults to `OnEmpty =
+	///    GetDefault`.
+	/// 3. [`ResultQuery`](frame_support::storage::types::ResultQuery): Returns `Result<V, E>`,
+	///    where `V` is the value type.
+	///
+	/// See [`QueryKind`](frame_support::storage::types::QueryKindTrait) for further examples.
+	///
+	/// ### Optimized Appending
+	///
+	/// All storage items — such as
+	/// [`StorageValue`](frame_support::storage::types::StorageValue),
+	/// [`StorageMap`](frame_support::storage::types::StorageMap), and their variants—offer an
+	/// `::append()` method optimized for collections. Using this method avoids the
+	/// inefficiency of decoding and re-encoding entire collections when adding items. For
+	/// instance, consider the storage declaration `type MyVal<T> = StorageValue<_, Vec<u8>,
+	/// ValueQuery>`. With `MyVal` storing a large list of bytes, `::append()` lets you
+	/// directly add bytes to the end in storage without processing the full list. Depending on
+	/// the storage type, additional key specifications may be needed.
+	///
+	/// #### Example
+	#[doc = docify::embed!("src/lib.rs", example_storage_value_append)]
+	/// Similarly, there also exists a `::try_append()` method, which can be used when handling
+	/// types where an append operation might fail, such as a
+	/// [`BoundedVec`](frame_support::BoundedVec).
+	///
+	/// #### Example
+	#[doc = docify::embed!("src/lib.rs", example_storage_value_try_append)]
+	/// ### Optimized Length Decoding
+	///
+	/// All storage items — such as
+	/// [`StorageValue`](frame_support::storage::types::StorageValue),
+	/// [`StorageMap`](frame_support::storage::types::StorageMap), and their counterparts —
+	/// incorporate the `::decode_len()` method. This method allows for efficient retrieval of
+	/// a collection's length without the necessity of decoding the entire dataset.
+	/// #### Example
+	#[doc = docify::embed!("src/lib.rs", example_storage_value_decode_len)]
+	/// ### Hashers
+	///
+	/// For all storage types, except
+	/// [`StorageValue`](frame_support::storage::types::StorageValue), a set of hashers needs
+	/// to be specified. The choice of hashers is crucial, especially in production chains. The
+	/// purpose of storage hashers in maps is to ensure the keys of a map are
+	/// uniformly distributed. An unbalanced map/trie can lead to inefficient performance.
+	///
+	/// In general, hashers are categorized as either cryptographically secure or not. The
+	/// former is slower than the latter. `Blake2` and `Twox` serve as examples of each,
+	/// respectively.
+	///
+	/// As a rule of thumb:
+	///
+	/// 1. If the map keys are not controlled by end users, or are cryptographically secure by
+	/// definition (e.g., `AccountId`), then the use of cryptographically secure hashers is NOT
+	/// required.
+	/// 2. If the map keys are controllable by the end users, cryptographically secure hashers
+	/// should be used.
+	///
+	/// For more information, look at the types that implement
+	/// [`frame_support::StorageHasher`](frame_support::StorageHasher).
+	///
+	/// Lastly, it's recommended for hashers with "concat" to have reversible hashes. Refer to
+	/// the implementors section of
+	/// [`hash::ReversibleStorageHasher`](frame_support::hash::ReversibleStorageHasher).
+	///
+	/// ### Prefixes
+	///
+	/// Internally, every storage type generates a "prefix". This prefix serves as the initial
+	/// segment of the key utilized to store values in the on-chain state (i.e., the final key
+	/// used in [`sp_io::storage`](sp_io::storage)). For all storage types, the following rule
+	/// applies:
+	///
+	/// > The storage prefix begins with `twox128(pallet_prefix) ++ twox128(STORAGE_PREFIX)`,
+	/// > where
+	/// > `pallet_prefix` is the name assigned to the pallet instance in
+	/// > [`frame_support::construct_runtime`](frame_support::construct_runtime), and
+	/// > `STORAGE_PREFIX` is the name of the `type` aliased to a particular storage type, such
+	/// > as
+	/// > `Foo` in `type Foo<T> = StorageValue<..>`.
+	///
+	/// For [`StorageValue`](frame_support::storage::types::StorageValue), no additional key is
+	/// required. For map types, the prefix is extended with one or more keys defined by the
+	/// map.

+	///
+	/// The following attribute macros can be used in conjunction with the `#[storage]` macro:
+	///
+	/// * [`macro@getter`]: Creates a custom getter function.
+	/// * [`macro@storage_prefix`]: Overrides the default prefix of the storage item.
+	/// * [`macro@unbounded`]: Declares the storage item as unbounded.
+	///
+	/// #### Example
+	/// ```
+	/// #[frame_support::pallet]
+	/// mod pallet {
+	///     # use frame_support::pallet_prelude::*;
+	///     # #[pallet::config]
+	///     # pub trait Config: frame_system::Config {}

Subject: [PATCH 074/211] fix substrate-node-template generation (#2050)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

# Description

This PR updates the node-template-release generation binary as well as
the `node-template-release.sh` file so that we can automatically push
updates to the [substrate-node-template
repository](https://github.com/substrate-developer-hub/substrate-node-template).
I assume this part was not updated after the substrate project has been
moved into the polkadot-sdk mono repo.

# Adjustments
- extend the `node-template-release.sh` to support the substrate
child-folder
- update the `SUBSTRATE_GIT_URL`
- fix the Cargo.toml filter (so that it does not include any
non-relevant .toml files)
- set the workspace-edition to 2021

# Note
In order to auto-generate the artifacts [this
line](https://github.com/paritytech/polkadot-sdk/blob/master/.gitlab/pipeline/build.yml#L320C15-L320C15)
needs to be included in the build.yml script again. Since I do not have
access to the (probably) internal gitlab environment I hope that someone
with actual access can introduce that change.
I also do not know how the auto-publish feature works so that would be
another thing to add later on.

From: Oliver Tale-Yazdi <oliver.tale-yazdi@parity.io>
Date: Wed, 1 Nov 2023 22:11:28 +0100
Subject: [PATCH 076/211] [FRAME] Short-circuit fungible self transfer (#2118)

Changes:
- Change the fungible(s) logic to treat a self-transfer as No-OP (as
long as all pre-checks pass).

Note that the self-transfer case will not emit an event since no state
was changed.

Subject: [PATCH 077/211] [testnet] Add `AssetHubRococo` <-> `AssetHubWestend`
 asset bridging support (#1967)

## Summary

Asset bridging support for AssetHub**Rococo** <-> AssetHub**Wococo** was
added [here](https://github.com/paritytech/polkadot-sdk/pull/1215), so
now we aim to bridge AssetHub**Rococo** and AssetHub**Westend**. (And
perhaps retire AssetHubWococo and the Wococo chains).

## Solution

**bridge-hub-westend-runtime**
- added new runtime as a copy of `bridge-hub-rococo-runtime`
- added support for bridging to `BridgeHubRococo`
- added tests and benchmarks

**bridge-hub-rococo-runtime**
- added support for bridging to `BridgeHubWestend`
- added tests and benchmarks
- internal refactoring by splitting bridge configuration per network,
e.g., `bridge_to_whatevernetwork_config.rs`.

**asset-hub-rococo-runtime**
- added support for asset bridging to `AssetHubWestend` (allows to
receive only WNDs)
- added new xcm router for `Westend`
- added tests and benchmarks

**asset-hub-westend-runtime**
- added support for asset bridging to `AssetHubRococo` (allows to
receive only ROCs)
- added new xcm router for `Rococo`
- added tests and benchmarks

## Deployment

All changes will be deployed as a part of
https://github.com/paritytech/polkadot-sdk/issues/1988.

## TODO

- [x] benchmarks for all pallet instances
- [x] integration tests
- [x] local run scripts

+# Bridges Tests for Local Rococo <> Wococo Bridge
+
+This folder contains [zombienet](https://github.com/paritytech/zombienet/) based integration tests for both
+onchain and offchain bridges code. Due to some
+[technical diffuculties](https://github.com/paritytech/parity-bridges-common/pull/2649#issue-1965339051), we
+are using native zombienet provider, which means that you need to build some binaries locally.
+
+To start those tests, you need to:
+
+- download latest [zombienet release](https://github.com/paritytech/zombienet/releases);
+
+- build Polkadot binary by running `cargo build -p polkadot --release` command in the
+[`polkadot-sdk`](https://github.com/paritytech/polkadot-sdk) repository clone;
+
+- build Polkadot Parachain binary by running `cargo build -p polkadot-parachain-bin --release` command in the
+[`polkadot-sdk`](https://github.com/paritytech/polkadot-sdk) repository clone;
+
+- ensure that you have [`node`](https://nodejs.org/en) installed. Additionally, we'll need globally installed
+`polkadot/api-cli` package (use `npm install -g @polkadot/api-cli@beta` to install it);
+
+- build Substrate relay by running `cargo build -p substrate-relay --release` command in the
+[`parity-bridges-common`](https://github.com/paritytech/parity-bridges-common) repository clone.
+
+- copy fresh `substrate-relay` binary, built in previous point, to the `~/local_bridge_testing/bin/substrate-relay`;
+
+- change the `POLKADOT_SDK_FOLDER` and `ZOMBIENET_BINARY_PATH` (and ensure that the nearby variables
+have correct values) in the `./run-tests.sh`.
+
+After that, you could run tests with the `./run-tests.sh` command. Hopefully, it'll show the
+"All tests have completed successfully" message in the end. Otherwise, it'll print paths to zombienet
+process logs, which, in turn, may be used to track locations of all spinned relay and parachain nodes.

Subject: [PATCH 081/211] Make `ExecResult` encodable (#1809)

# Description
We derive few useful traits on `ErrorOrigin` and `ExecError`, including
`codec::Encode` and `codec::Decode`, so that `ExecResult` is
en/decodable as well. This is required for a contract mocking feature
(already prepared in drink:
https://github.com/Cardinal-Cryptography/drink/pull/61). In more detail:
`ExecResult` must be passed from runtime extension, through runtime
interface, back to the pallet, which requires that it is serializable to
bytes in some form (or implements some rare, auxiliary traits).

**Impact on runtime size**: Since most of these traits is used directly
in the pallet now, compiler should be able to throw it out (and thus we
bring no new overhead). However, they are very useful in secondary tools
like drink or other testing libraries.

# Checklist

- [x] My PR includes a detailed description as outlined in the
"Description" section above
- [ ] My PR follows the [labeling requirements](CONTRIBUTING.md#Process)
of this project (at minimum one label for `T`
  required)
- [x] I have made corresponding changes to the documentation (if
applicable)
- [x] I have added tests that prove my fix is effective or that my
feature works (if applicable)

Subject: [PATCH 084/211] Use `Message Queue` as DMP and XCMP dispatch queue
 (#1246)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

(imported from https://github.com/paritytech/cumulus/pull/2157)

## Changes

This MR refactores the XCMP, Parachains System and DMP pallets to use
the [MessageQueue](https://github.com/paritytech/substrate/pull/12485)
for delayed execution of incoming messages. The DMP pallet is entirely
replaced by the MQ and thereby removed. This allows for PoV-bounded
execution and resolves a number of issues that stem from the current
work-around.

All System Parachains adopt this change.
The most important changes are in `primitives/core/src/lib.rs`,
`parachains/common/src/process_xcm_message.rs`,
`pallets/parachain-system/src/lib.rs`, `pallets/xcmp-queue/src/lib.rs`
and the runtime configs.

### DMP Queue Pallet

The pallet got removed and its logic refactored into parachain-system.
Overweight message management can be done directly through the MQ
pallet.

Final undeployment migrations are provided by
`cumulus_pallet_dmp_queue::UndeployDmpQueue` and `DeleteDmpQueue` that
can be configured with an aux config trait like:

```rust
parameter_types! {
	pub const DmpQueuePalletName: &'static str = \"DmpQueue\" < CHANGE ME;
	pub const RelayOrigin: AggregateMessageOrigin = AggregateMessageOrigin::Parent;
}

impl cumulus_pallet_dmp_queue::MigrationConfig for Runtime {
	type PalletName = DmpQueuePalletName;
	type DmpHandler = frame_support::traits::EnqueueWithOrigin<MessageQueue, RelayOrigin>;
	type DbWeight = <Runtime as frame_system::Config>::DbWeight;
}

// And adding them to your Migrations tuple:
pub type Migrations = (
	...
	cumulus_pallet_dmp_queue::UndeployDmpQueue<Runtime>,
	cumulus_pallet_dmp_queue::DeleteDmpQueue<Runtime>,
);
```

### XCMP Queue pallet

Removed all dispatch queue functionality. Incoming XCMP messages are now
either: Immediately handled if they are Signals, enqueued into the MQ
pallet otherwise.

New config items for the XCMP queue pallet:
```rust
/// The actual queue implementation that retains the messages for later processing.
type XcmpQueue: EnqueueMessage<ParaId>;

/// How a XCM over HRMP from a sibling parachain should be processed.
type XcmpProcessor: ProcessMessage<Origin = ParaId>;

/// The maximal number of suspended XCMP channels at the same time.
#[pallet::constant]
type MaxInboundSuspended: Get<u32>;
```

How to configure those:

```rust
// Use the MessageQueue pallet to store messages for later processing. The `TransformOrigin` is needed since
// the MQ pallet itself operators on `AggregateMessageOrigin` but we want to enqueue `ParaId`s.
type XcmpQueue = TransformOrigin<MessageQueue, AggregateMessageOrigin, ParaId, ParaIdToSibling>;

// Process XCMP messages from siblings. This is type-safe to only accept `ParaId`s. They will be dispatched
// with origin `Junction::Sibling(…)`.
type XcmpProcessor = ProcessFromSibling<
	ProcessXcmMessage<
		AggregateMessageOrigin,
		xcm_executor::XcmExecutor<xcm_config::XcmConfig>,
		RuntimeCall,
	>,
>;

// Not really important what to choose here. Just something larger than the maximal number of channels.
type MaxInboundSuspended = sp_core::ConstU32<1_000>;
```

The `InboundXcmpStatus` storage item was replaced by
`InboundXcmpSuspended` since it now only tracks inbound queue suspension
and no message indices anymore.

Now only sends the most recent channel `Signals`, as all prio ones are
out-dated anyway.

### Parachain System pallet

For `DMP` messages instead of forwarding them to the `DMP` pallet, it
now pushes them to the configured `DmpQueue`. The message processing
which was triggered in `set_validation_data` is now being done by the MQ
pallet `on_initialize`.

XCMP messages are still handed off to the `XcmpMessageHandler`
(XCMP-Queue pallet) - no change here.

New config items for the parachain system pallet:
```rust
/// Queues inbound downward messages for delayed processing.
///
/// Analogous to the `XcmpQueue` of the XCMP queue pallet.
type DmpQueue: EnqueueMessage<AggregateMessageOrigin>;
```

How to configure:
```rust
/// Use the MQ pallet to store DMP messages for delayed processing.
type DmpQueue = MessageQueue;
```

## Message Flow

The flow of messages on the parachain side. Messages come in from the
left via the `Validation Data` and finally end up at the `Xcm Executor`
on the right.

## Further changes

- Bumped the default suspension, drop and resume thresholds in
`QueueConfigData::default()`.
- `XcmpQueue::{suspend_xcm_execution, resume_xcm_execution}` errors when
they would be a noop.
- Properly validate the `QueueConfigData` before setting it.
- Marked weight files as auto-generated so they wont auto-expand in the
MR files view.
- Move the `hypothetical` asserts to `frame_support` under the name
`experimental_hypothetically`

Questions:
- [ ] What about the ugly `#[cfg(feature = \"runtime-benchmarks\")]` in
the runtimes? Not sure how to best fix. Just having them like this makes
tests fail that rely on the real message processor when the feature is
enabled.
- [ ] Need a good weight for `MessageQueueServiceWeight`. The scheduler
already takes 80% so I put it to 10% but that is quite low.

TODO:
- [x] Remove c&p code after
https://github.com/paritytech/polkadot/pull/6271
- [x] Use `HandleMessage` once it is public in Substrate
- [x] fix `runtime-benchmarks` feature
https://github.com/paritytech/polkadot/pull/6966
- [x] Benchmarks
- [x] Tests
- [ ] Migrate `InboundXcmpStatus` to `InboundXcmpSuspended`
- [x] Possibly cleanup Migrations (DMP+XCMP)
- [x] optional: create `TransformProcessMessageOrigin` in Substrate and
replace `ProcessFromSibling`
- [ ] Rerun weights on ref HW

From 15a34838819f09f3bcfb3c05c08fb53934d8efc4 Mon Sep 17 00:00:00 2001
From: Richard Melkonian <35300528+0xmovses@users.noreply.github.com>
Date: Thu, 2 Nov 2023 18:02:01 +0000
Subject: [PATCH 085/211] Create new trait for non-dedup storage decode (#1932)

- This adds the new trait `StorageDecodeNonDedupLength` and implements
them for `BTreeSet` and its bounded types.
- New unit test has been added to cover the case.
- See linked
[issue](https://github.com/paritytech/polkadot-sdk/issues/126) which
outlines the original issue.

Note that the added trait here doesn't add new logic but improves
semantics.

Subject: [PATCH 086/211] [testnet] Allow governance to control fees for Rococo
 <> Westend bridge (#2139)

Right now governance could only control byte-fee component of Rococo <>
Westend message fees (paid at Asset Hubs). This PR changes it a bit:
1) governance now allowed to control both fee components - byte fee and
base fee;
2) base fee now includes cost of "default" delivery and confirmation
transactions, in addition to `ExportMessage` instruction cost.

Subject: [PATCH 088/211] substrate: sysinfo: Expose failed hardware
 requirements (#2144)

The check_hardware functions does not give us too much information as to
what is failing, so let's return the list of failed metrics, so that callers can print
it.

This would make debugging easier, rather than try to guess which
dimension is actually failing.

Subject: [PATCH 092/211] Add deprecation checklist document for Substrate
 (#1583)

fixes https://github.com/paritytech/polkadot-sdk/issues/182

This PR adds a document with recommendations of how deprecations should
be handled. Initiated within FRAME, this checklist could be extended to
the rest of the repo.

I want to quote here a comment from @kianenigma that summarizes the
spirit of this new document:
> I would see it as a guideline of "what an extensive deprecation
process looks like". As the author of a PR, you should match this
against your "common sense" and see if it is needed or not. Someone else
can nudge you to "hey, this is an important PR, you should go through
the deprecation process".
>
> For some trivial things, all the steps might be an overkill.

+# Deprecation Checklist
+
+This deprecation checklist makes sense while we don’t use [SemVer](https://semver.org/).
+After that, this document will most likely change.
+As deprecation and removal of existing code can happen on any release, we need to be mindful that external builders
+could be impacted by the changes we make.
+The deprecation checklist tries to mitigate this impact, while still keeping the developer experience, the DevEx, as
+smooth as possible.
+
+To start a deprecation process, a new issue with the label `T15-deprecation` needs to be created for correct tracking.
+Then these are the actions to take:
+
+## Hard deprecate by adding a warning message
+
+The warning message shall include a removal month and year, which is suggested to be 6 months after the deprecation
+notice is released.
+This means that the code will be removed in a release within that month (or after, but never before). Please use this
+template, doing so makes it easy to search through the code base:
+
+```rust
+#[deprecated(note = "[DEPRECATED] will be removed after [DATE]. [ALTERNATIVE]")]
+```
+`[ALTERNATIVE]` won't always be possible but offer it if it is.
+
+E.g.
+```rust
+#[deprecated(note = "`GenesisConfig` will be removed after December 2023. Use `RuntimeGenesisConfig` instead.")]
+```
+
+Some pieces of code cannot be labeled as deprecated, like [reexports](https://github.com/rust-lang/rust/issues/30827)
+or [dispatchables](https://github.com/paritytech/polkadot-sdk/issues/182#issuecomment-1691684159), for instance.
+In cases like that we can only make a visible enough comment, and make sure that we [announce the deprecation properly](#announce-the-deprecation-and-removal).
+
+## Remove usage of the deprecated code in the code base
+
+Just make sure that we are not using the deprecated code ourselves.
+If you added the deprecation warning from the previous step, this can be done by making sure that warning is not shown
+when building the code.
+
+## Update examples and tutorials
+
+Make sure that the rust docs are updated.
+We also need [https://docs.substrate.io/](https://docs.substrate.io/) to be updated accordingly. The repo behind it is
+[https://github.com/substrate-developer-hub/substrate-docs](https://github.com/substrate-developer-hub/substrate-docs).
+
+## Announce the deprecation and removal
+
+**At minimum they should be noted in the release log.** Please see how to document a PR [here](https://github.com/paritytech/polkadot-sdk/blob/master/docs/CONTRIBUTING.md#documentation).
+There you can give instructions based on the audience and tell them what they need to do to upgrade the code.
+
+Some breaking changes have a bigger impact than others. When the impact is big the release note is not enough, though
+it should still be the primary place for the notice. You can link back to the changelog files in other channels if you
+want to announce it somewhere else.
+Make sure you are as loud as you need to be for the magnitude of the breaking change.
+
+## Removal version is planned
+
+Depending on the removal date indicated in the deprecation warning in the [first step](#hard-deprecate-by-adding-a-warning-message),
+the nature and the importance of the change, it might make sense to coordinate the release with other developers and
+with the Release team.
+
+## Deprecated code is removed
+
+The deprecated code finally gets removed.
+Don’t forget to [announce this accordingly](#announce-the-deprecation-and-removal).
+
+✅ In order to not forget any of these steps, consider using this template in your deprecation issue:
+
+```markdown
+### Tasks
+
+- [ ] Deprecate code by adding a warning message
+- [ ] Remove usage of the deprecated code in the code base
+- [ ] Update examples and tutorials
+- [ ] Announce code deprecation
+- [ ] Plan removal version
+- [ ] Announce code removal
+- [ ] Remove deprecated code
+```

Subject: [PATCH 094/211] `sc-block-builder`: Remove `BlockBuilderProvider`
 (#2099)

The `BlockBuilderProvider` was a trait that was defined in
`sc-block-builder`. The trait was implemented for `Client`. This
basically meant that you needed to import `sc-block-builder` any way to
have access to the block builder. So, this trait was not providing any
real value. This pull request is removing the said trait. Instead of the
trait it introduces a builder for creating a `BlockBuilder`. The builder
currently has the quite fabulous name `BlockBuilderBuilder` (I'm open to
any better name :sweat_smile:). The rest of the pull request is about
replacing the old trait with the new builder.

# Downstream code changes

If you used `new_block` or `new_block_at` before you now need to switch
it over to the new `BlockBuilderBuilder` pattern:

```rust
// `new` requires a type that implements `CallApiAt`.
let mut block_builder = BlockBuilderBuilder::new(client)

Subject: [PATCH 095/211] Identity pallet improvements (#2048)

This PR is a follow up to #1661

- [x] rename the `simple` module to `legacy`
- [x] fix benchmarks to disregard the number of additional fields
- [x] change the storage deposits to charge per encoded byte of the
identity information instance, removing the need for `fn
additional(&self) -> usize` in `IdentityInformationProvider`
- [x] ~add an extrinsic to rejig deposits to account for the change
above~
- [ ] ~ensure through proper configuration that the new byte-based
deposit is always lower than whatever is reserved now~
- [x] remove `IdentityFields` from the `set_fields` extrinsic signature,
as per [this
discussion](https://github.com/paritytech/polkadot-sdk/pull/1661#discussion_r1371703403)

> ensure through proper configuration that the new byte-based deposit is
always lower than whatever is reserved now

Not sure this is needed anymore. If the new deposits are higher than
what is currently on chain and users don't have enough funds to reserve
what is needed, the extrinisc fails and they're basically grandfathered
and frozen until they add more funds and/or make a change to their
identity. This behavior seems fine to me. Original idea
[here](https://github.com/paritytech/polkadot-sdk/pull/1661#issuecomment-1779606319).

> add an extrinsic to rejig deposits to account for the change above

This was initially implemented but now removed from this PR in favor of
the implementation detailed
[here](https://github.com/paritytech/polkadot-sdk/pull/2088).

Subject: [PATCH 096/211] cumulus test runtime: remove `GenesisExt` (#2147)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This PR removes the `GenesisExt` wrapper over the `GenesisRuntimeConfig`
in `cumulus-test-service`. Initialization of values that were performed
by `GenesisExt::BuildStorage` was moved into `test_pallet` genesis.

Subject: [PATCH 101/211] `chain-spec`: getting ready for native-runtime-free
 world (#1256)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This PR prepares chains specs for _native-runtime-free_  world.

This PR has following changes:
- `substrate`:
  - adds support for:
- JSON based `GenesisConfig` to `ChainSpec` allowing interaction with
runtime `GenesisBuilder` API.
- interacting with arbitrary runtime wasm blob to[
`chain-spec-builder`](https://github.com/paritytech/substrate/blob/3ef576eaeb3f42610e85daecc464961cf1295570/bin/utils/chain-spec-builder/src/lib.rs#L46)
command line util,
- removes
[`code`](https://github.com/paritytech/substrate/blob/3ef576eaeb3f42610e85daecc464961cf1295570/frame/system/src/lib.rs#L660)
from `system_pallet`
  - adds `code` to the `ChainSpec`
- deprecates
[`ChainSpec::from_genesis`](https://github.com/paritytech/substrate/blob/3ef576eaeb3f42610e85daecc464961cf1295570/client/chain-spec/src/chain_spec.rs#L263),
but also changes the signature of this method extending it with `code`
argument.
[`ChainSpec::builder()`](https://github.com/paritytech/substrate/blob/20bee680ed098be7239cf7a6b804cd4de267983e/client/chain-spec/src/chain_spec.rs#L507)
should be used instead.
- `polkadot`:
- all references to `RuntimeGenesisConfig` in `node/service` are
removed,
- all
`(kusama|polkadot|versi|rococo|wococo)_(staging|dev)_genesis_config`
functions now return the JSON patch for default runtime `GenesisConfig`,
  - `ChainSpecBuilder` is used, `ChainSpec::from_genesis` is removed,

- `cumulus`:
  - `ChainSpecBuilder` is used, `ChainSpec::from_genesis` is removed,
- _JSON_ patch configuration used instead of `RuntimeGenesisConfig
struct` in all chain specs.

 Substrate chain configurations.
 
-This crate contains structs and utilities to declare
-a runtime-specific configuration file (a.k.a chain spec).
-
-Basic chain spec type containing all required parameters is
-[`ChainSpec`](https://docs.rs/sc-chain-spec/latest/sc_chain_spec/struct.GenericChainSpec.html). It can be extended with
-additional options that contain configuration specific to your chain.
-Usually the extension is going to be an amalgamate of types exposed
-by Substrate core modules. To allow the core modules to retrieve
-their configuration from your extension you should use `ChainSpecExtension`
-macro exposed by this crate.
-
-```rust
-use std::collections::HashMap;
-use sc_chain_spec::{GenericChainSpec, ChainSpecExtension};
-
-#[derive(Clone, Debug, serde::Serialize, serde::Deserialize, ChainSpecExtension)]
-pub struct MyExtension {
-		pub known_blocks: HashMap<u64, String>,
-}
-
-pub type MyChainSpec<G> = GenericChainSpec<G, MyExtension>;
-```
-
-Some parameters may require different values depending on the
-current blockchain height (a.k.a. forks). You can use `ChainSpecGroup`
-macro and provided [`Forks`](https://docs.rs/sc-chain-spec/latest/sc_chain_spec/struct.Forks.html) structure to put
-such parameters to your chain spec.
-This will allow to override a single parameter starting at specific
-block number.
-
-```rust
-use sc_chain_spec::{Forks, ChainSpecGroup, ChainSpecExtension, GenericChainSpec};
-
-#[derive(Clone, Debug, serde::Serialize, serde::Deserialize, ChainSpecGroup)]
-pub struct ClientParams {
-		max_block_size: usize,
-		max_extrinsic_size: usize,
-}
-
-#[derive(Clone, Debug, serde::Serialize, serde::Deserialize, ChainSpecGroup)]
-pub struct PoolParams {
-		max_transaction_size: usize,
-}
-
-#[derive(Clone, Debug, serde::Serialize, serde::Deserialize, ChainSpecGroup, ChainSpecExtension)]
-pub struct Extension {
-		pub client: ClientParams,
-		pub pool: PoolParams,
-}
-
-pub type BlockNumber = u64;
-
-/// A chain spec supporting forkable `ClientParams`.
-pub type MyChainSpec1<G> = GenericChainSpec<G, Forks<BlockNumber, ClientParams>>;
-
-/// A chain spec supporting forkable `Extension`.
-pub type MyChainSpec2<G> = GenericChainSpec<G, Forks<BlockNumber, Extension>>;
-```
-
-It's also possible to have a set of parameters that is allowed to change
-with block numbers (i.e. is forkable), and another set that is not subject to changes.
-This is also possible by declaring an extension that contains `Forks` within it.
-
-
-```rust
-use serde::{Serialize, Deserialize};
-use sc_chain_spec::{Forks, GenericChainSpec, ChainSpecGroup, ChainSpecExtension};
-
-#[derive(Clone, Debug, Serialize, Deserialize, ChainSpecGroup)]
-pub struct ClientParams {
-		max_block_size: usize,
-		max_extrinsic_size: usize,
-}
-
-#[derive(Clone, Debug, Serialize, Deserialize, ChainSpecGroup)]
-pub struct PoolParams {
-		max_transaction_size: usize,
-}
-
-#[derive(Clone, Debug, Serialize, Deserialize, ChainSpecExtension)]
-pub struct Extension {
-		pub client: ClientParams,
-		#[forks]
-		pub pool: Forks<u64, PoolParams>,
-}
-
-pub type MyChainSpec<G> = GenericChainSpec<G, Extension>;

-//! Substrate chain configurations.
+//! This crate includes structs and utilities for defining configuration files (known as chain
+//! specification) for both runtime and node.
+//!
+//! # Intro: Chain Specification
+//!
+//! The chain specification comprises parameters and settings that define the properties and an
+//! initial state of a chain. Users typically interact with the JSON representation of the chain
+//! spec. Internally, the chain spec is embodied by the [`GenericChainSpec`] struct, and specific
+//! properties can be accessed using the [`ChainSpec`] trait.
+//!
+//! In summary, although not restricted to, the primary role of the chain spec is to provide a list
+//! of well-known boot nodes for the blockchain network and the means for initializing the genesis
+//! storage. This initialization is necessary for creating a genesis block upon which subsequent
+//! blocks are built. When the node is launched for the first time, it reads the chain spec,
+//! initializes the genesis block, and establishes connections with the boot nodes.
+//!
+//! The JSON chain spec is divided into two main logical sections:
+//! - one section details general chain properties,
+//! - second explicitly or indirectly defines the genesis storage, which, in turn, determines the
+//!   genesis hash of the chain,
+//!
+//! The chain specification consists of the following fields:
+//!
+//! <table>
+//!   <thead>
+//!     <tr>
+//!       <th>Chain spec key</th>
+//!       <th>Description</th>
+//!     </tr>
+//!   </thead>

+//!
+//! # `genesis`: Initial Runtime State
+//!
+//! All nodes in the network must build subsequent blocks upon exactly the same genesis block.
+//!
+//! The information configured in the `genesis` section of a chain specification is used to build
+//! the genesis storage, which is essential for creating the genesis block, since the block header
+//! includes the storage root hash.
+//!
+//! The `genesis` key of the chain specification definition describes the
+//! initial state of the runtime. For example, it may contain:
+//! - an initial list of funded accounts,
+//! - the administrative account that controls the sudo key,
+//! - an initial authorities set for consensus, etc.
+//!
+//! As the compiled WASM blob of the runtime code is stored in the chain's state, the initial
+//! runtime must also be provided within the chain specification.
+//!
+//! In essence, the most important formats of genesis initial state are:
+//!
+//! <table>

+//!     </tr>
+//!   </tbody>
+//! </table>
+//!
+//! For production or long-lasting blockchains, using the `raw` format in the chain specification is
+//! recommended. Only the `raw` format guarantees that storage root hash will remain unchanged when
+//! the `RuntimeGenesisConfig` format changes due to software upgrade.
+//!
+//! JSON examples in the [following section](#json-chain-specification-example) illustrate the `raw`
+//! `patch` and full genesis fields.
+//!
+//! # From Initial State to Raw Genesis.
+//!
+//! To generate a raw genesis storage from the JSON representation of the runtime genesis config,
+//! the node needs to interact with the runtime.
+//!
+//! This interaction involves passing the runtime genesis config JSON blob to the runtime using the
+//! [`sp_genesis_builder::GenesisBuilder::build_config`] function. During this operation, the
+//! runtime converts the JSON representation of the genesis config into [`sp_io::storage`] items. It
+//! is a crucial step for computing the storage root hash, which is a key component in determining
+//! the genesis hash.
+//!
+//! Consequently, the runtime must support the [`sp_genesis_builder::GenesisBuilder`] API to
+//! utilize either `patch` or `full` formats.
+//!
+//! This entire process is encapsulated within the implementation of the [`BuildStorage`] trait,
+//! which can be accessed through the [`ChainSpec::as_storage_builder`] method. There is an
+//! intermediate internal helper that facilitates this interaction,
+//! [`GenesisConfigBuilderRuntimeCaller`], which serves as a straightforward wrapper for
+//! [`sc_executor::WasmExecutor`].
+//!
+//! In case of `raw` genesis state the node does not interact with the runtime regarding the
+//! computation of initial state.
+//!
+//! The plain and `raw` chain specification JSON blobs can be found in
+//! [JSON examples](#json-chain-specification-example) section.
+//!
+//! # Optional Code Mapping
+//!
+//! Optional map of `block_number` to `wasm_code`.
+//!
+//! The given `wasm_code` will be used to substitute the on-chain wasm code starting with the
+//! given block number until the `spec_version` on-chain changes. The given `wasm_code` should
+//! be as close as possible to the on-chain wasm code. A substitute should be used to fix a bug
+//! that cannot be fixed with a runtime upgrade, if for example the runtime is constantly
+//! panicking. Introducing new runtime APIs isn't supported, because the node
+//! will read the runtime version from the on-chain wasm code.
+//!
+//! Use this functionality only when there is no other way around it, and only patch the problematic
+//! bug; the rest should be done with an on-chain runtime upgrade.
+//!
+//! # Building a Chain Specification
+//!
+//! The [`ChainSpecBuilder`] should be used to create an instance of a chain specification. Its API
+//! allows configuration of all fields of the chain spec. To generate a JSON representation of the
+//! specification, use [`ChainSpec::as_json`].
+//!
+//! The sample code to generate a chain spec is as follows:
+#![doc = docify::embed!("src/chain_spec.rs", build_chain_spec_with_patch_works)]
+//! # JSON chain specification example
+//!
+//! The following are the plain and `raw` versions of the chain specification JSON files, resulting
+//! from executing of the above [example](#building-a-chain-specification):
+//! ```ignore
+#![doc = include_str!("../res/substrate_test_runtime_from_patch.json")]
+//! ```
+//! ```ignore
+#![doc = include_str!("../res/substrate_test_runtime_from_patch_raw.json")]
+//! ```
+//! The following example shows the plain full config version of chain spec:
+//! ```ignore
+#![doc = include_str!("../res/substrate_test_runtime_from_config.json")]
+//! ```
+//! The [`ChainSpec`] trait represents the API to access values defined in the JSON chain specification.

Subject: [PATCH 109/211] approval-voting improvement: include all tranche0
 assignments in one certificate  (#1178)

**_PR migrated from https://github.com/paritytech/polkadot/pull/6782_**

This PR will upgrade the network protocol to version 3 -> VStaging which
will later be renamed to V3. This version introduces a new kind of
assignment certificate that will be used for tranche0 assignments.
Instead of issuing/importing one tranche0 assignment per candidate,
there will be just one certificate per relay chain block per validator.
However, we will not be sending out the new assignment certificates,
yet. So everything should work exactly as before. Once the majority of
the validators have been upgraded to the new protocol version we will
enable the new certificates (starting at a specific relay chain block)
with a new client update.

There are still a few things that need to be done:

- [x] Use bitfield instead of Vec<CandidateIndex>:
https://github.com/paritytech/polkadot/pull/6802
  - [x] Fix existing approval-distribution and approval-voting tests
  - [x] Fix bitfield-distribution and statement-distribution tests
  - [x] Fix network bridge tests
  - [x] Implement todos in the code
  - [x] Add tests to cover new code
  - [x] Update metrics
  - [x] Remove the approval distribution aggression levels: TBD PR
  - [x] Parachains DB migration
  - [x] Test network protocol upgrade on Versi
  - [x] Versi Load test
  - [x] Add Zombienet test
  - [x] Documentation updates
- [x] Fix for sending DistributeAssignment for each candidate claimed by
a v2 assignment (warning: Importing locally an already known assignment)
 - [x]  Fix AcceptedDuplicate
 - [x] Fix DB migration so that we can still keep old data.
 - [x] Final Versi burn in

Subject: [PATCH 111/211] TryDecodeEntireState check for storage types and
 pallets (#1805)

### This PR is a port of this [PR for
substrate](https://github.com/paritytech/substrate/pull/13013) by
@kianenigma

Add infrastructure needed to have a Pallet::decode_entire_state(), which
makes sure all "typed" storage items defined in the pallet are
decode-able.

This is not enforced in any way at the moment. Teams who wish to
integrate/use this in the try-runtime feature flag should add
frame_support::storage::migration::EnsureStateDecodes as the LAST ITEM
of the runtime's custom migrations, and pass it to frame-executive. This
will make it usable in try-runtime on-runtime-upgrade.

This now catches cases like
https://github.com/paritytech/polkadot-sdk/pull/1969:
```pre
ERROR runtime::executive] failed to decode the value at key: Failed to decode value at key: 0x94eadf0156a8ad5156507773d0471e4ab8ebad86f546c7e0b135a4212aace339. Storage info StorageInfo { pallet_name: Ok("ParaScheduler"), storage_name: Ok("AvailabilityCores"), prefix: Err(Utf8Error { valid_up_to: 0, error_len: Some(1) }), max_values: Some(1), max_size: None }. Raw value: Some("0x0c010101010101")
```

... or:

Closes #241

Subject: [PATCH 112/211] Initialise on-chain `StorageVersion` for pallets
 added after genesis (#1297)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.

Subject: [PATCH 113/211] zombienet_tests: Fix genesis error in

There was a race in merging between
https://github.com/paritytech/polkadot-sdk/pull/1256 and
https://github.com/paritytech/polkadot-sdk/pull/1178, so this newly
added tests wasn't updated with the new path for the configuration, so
fix that.

 polkadot-runtime-common (#2187)

Part of #2186

The only usage of pallet-asset-rate is guarded by `runtime-benchmarks`
feature. I don't want ORML to be forced to include this pallet in deps
for no good reason.

explanations of events, this will then be shown externally. I noticed
this when reviewing [this

Subject: [PATCH 117/211] Disable incoming light-client connections for minimal
 relay node (#2202)

When running with `--relay-chain-rpc-url` we received multiple reports
of high traffic that disappears when `--in-peers-light 0` is set. Indeed
it does not make much sense for light clients to connect to the minimal
node since it is not running the block announce protocol and the
request/response protocol for light clients.

This is intended to alleviate the traffic issues for now.

Subject: [PATCH 118/211] XCM builder pattern (#2107)

Added a proc macro to be able to write XCMs using the builder pattern.
This means we go from having to do this:

```rust
let message: Xcm<()> = Xcm(vec![
  WithdrawAsset(assets),
  BuyExecution { fees: asset, weight_limit: Unlimited },
  DepositAsset { assets, beneficiary },
]);
```

to this:

```rust
let message: Xcm<()> = Xcm::builder()
  .withdraw_asset(assets)
  .buy_execution(asset, Unlimited),
  .deposit_asset(assets, beneficiary)
  .build();
```

Subject: [PATCH 119/211] [testnets][xcm-emulator] add bridge-hub-westend and
 hook it up to emulator (#2204)

`bridge-hub-westend-runtime` was added to cumulus/parachains, but wasn't
hooked up to xcm-emulator to run tests against it.

This commit addresses that ^.

Subject: [PATCH 122/211] Adding gitspiegel-trigger workflow (#2135)

GitHub has a setting that requires manual click for executing GHA on the
branch, for the first-time contributors:
https://docs.github.com/en/actions/managing-workflow-runs/approving-workflow-runs-from-public-forks.

After this PR, gitspiegel will respect that setting. So, for PRs from
first-time contributors, gitspiegel won't do mirroring until the button
in PR is clicked. More info:

Subject: [PATCH 123/211] validate-block: Fix `TrieCache` implementation
 (#2214)

The trie cache implementation was ignoring the `storage_root` when
setting up the value cache. The problem with this is that the value
cache works using `storage_keys` and these keys are not unique across
different tries. A block can actually have different tries (main trie
and multiple child tries). This pull request fixes the issue by not
ignoring the `storage_root` and returning an unique `value_cache` per
`storage_root`. It also adds a test for the seen bug and improves
documentation that this doesn't happen again.

Subject: [PATCH 125/211] [xcm-emulator] Chains generic over Network &
 Integration tests restructure (#2092)

Closes:
- #1383
- Declared chains can be now be imported and reused in a different
crate.
- Chain declaration are now generic over a generic type `N` (the
Network)
- #1389
- Solved #1383, chains and networks declarations can be restructure to
avoid having to compile all chains when running integrations tests where
are not needed.
- Chains are now declared on its own crate (removed from
`integration-tests-common`)
- Networks are now declared on its own crate (removed from
`integration-tests-common`)
    - Integration tests will import only the relevant Network crate
- `integration-tests-common` is renamed to
`emulated-integration-tests-common`

All this is necessary to be able to implement what is described here:
https://github.com/paritytech/roadmap/issues/56#issuecomment-1777010553

Subject: [PATCH 126/211] `sc-chain-spec`: add support for custom host
 functions (#2190)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Genesis building in runtime may involve calling some custom host
functions. This PR allows to pass `HostFunctions` into the `ChainSpec`
struct, which in turn are passed to `WasmExecutor`. The `ChainSpec` now
has extended host functions type parameter:
```
pub struct ChainSpec<G, E = NoExtension, EHF = ()>
```
which will be combined with the default set
(`sp_io::SubstrateHostFunctions`) in an instance of `WasmExecutor` used
to build the genesis config.

Fix for #2188

Subject: [PATCH 127/211] integrations-test: `build_genesis_storage` name fix
 (#2232)

Some legacy tests were mistakenly merged in #1256 for `emulated-integration-tests-common` crate.
This PR fixes the function name `build_genesis_storage` (no need to use `legacy` suffix, even though the genesis is built from `RuntimeGenesisConfig`).

Subject: [PATCH 128/211] Add prospective-parachain subsystem to
 minimal-relay-node + QoL improvements (#2223)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This PR contains some fixes and cleanups for parachain nodes:

1. When using async backing, node no longer complains about being unable
to reach the prospective-parachain subsystem.
2. Parachain warp sync now informs users that the finalized para block
has been retrieved.
```
2023-11-08 13:24:42 [Parachain] 🎉 Received finalized parachain header #5747719 (0xa0aa…674b) from the relay chain.
```
3. When a user supplied an invalid `--relay-chain-rpc-url`, we were
crashing with a very verbose message. Removed the `expect` and improved
the error message.
```
2023-11-08 13:57:56 [Parachain] No valid RPC url found. Stopping RPC worker.
2023-11-08 13:57:56 [Parachain] Essential task `relay-chain-rpc-worker` failed. Shutting down service.
Error: Service(Application(WorkerCommunicationError("RPC worker channel closed. This can hint and connectivity issues with the supplied RPC endpoints. Message: oneshot canceled")))
```

Subject: [PATCH 130/211] BridgeHub Runtimes: Change registration order of
 `MessageQueue` pallet (#2230)

This PR changes the registration order of the `MessageQueue` pallet so
that it is registered last.

This is necessary so that the
[on_initialize](https://github.com/Snowfork/snowbridge/blob/df8d5da82e517a65fb0858a4f2ead533290336b5/parachain/pallets/outbound-queue/src/lib.rs#L267)
hooks for Snowbridge can run before `MessageQueue` delivers messages
using its own `on_initialize`.

Generally, I think this is preferable regardless of Snowbridge's
particular requirements. Other pallets may want to do housekeeping
before MessageQueue starts delivering messages.

I'm hoping this PR, if accepted, can be included in the same release as
https://github.com/paritytech/polkadot-sdk/pull/1246. As otherwise,
changing the order of pallet registration is an ABI-breaking change.

Subject: [PATCH 131/211] Rococo: Build two versions of the wasm binary (#2229)

One for local networks with `fast-runtime` feature activated (1 minute
sessions) and one without the feature activated that will be the default
that runs with 1 hour long sessions.

Subject: [PATCH 137/211] sc-state-db: Keep track of `LAST_PRUNED` after warp
 syncing (#2228)

When warp syncing we import the target block with all its state.
However, we didn't store the `LAST_PRUNED` block which would then lead
to `pruning` to forget about the imported block after a restart of the
node. We just set `LAST_PRUNED` to the parent block of the warp sync
target block to fix this issue.

Subject: [PATCH 140/211] [pallet-message-queue] Implement
 impl_trait_for_tuples for QueuePausedQuery (#2227)

These changes are required so that the bridgehub system runtimes can
more easily be configured with multiple message processors

Example usage:

```rust
use frame_support::traits::QueuePausedQuery;

impl pallet_message_queue::Config for Runtime {
    type QueuePausedQuery = (A, B, C)
}

Subject: [PATCH 141/211] Improve `VersionedMigration` naming conventions
 (#2264)

As suggested by @ggwpez
(https://github.com/paritytech/polkadot-sdk/pull/2142#discussion_r1388145872),
remove the `VersionChecked` prefix from version checked migrations (but
leave `VersionUnchecked` prefixes)

Subject: [PATCH 142/211] Contracts: Add XCM traits to interface with contracts
 (#2086)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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>;
}
```

+      We are introducing a new set of `XcmController` traits in `pallet-xcm`.
+      These traits extract functionality from `pallet-xcm` and provide high-level interaction with XCM. 
+      They enable other pallets, like `pallet_contracts`, to rely on these traits instead of tight coupling to `pallet-xcm` itself.

From 0c5dcca9e3cef6b2f456fccefd9f6c5e43444053 Mon Sep 17 00:00:00 2001
From: Daniel Olano <me@olanod.com>
Date: Sat, 11 Nov 2023 20:34:08 +0100
Subject: [PATCH 143/211] Add `s` utility function to frame support (#2275)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A utility function I consider quite useful to declare string literals
that are backed by an array.

Subject: [PATCH 144/211] Unify `ChainSync` actions under one enum (#2180)

All `ChainSync` actions that `SyncingEngine` should perform are unified
under one `ChainSyncAction`. Processing of these actions put into a
single place after `select!` in `SyncingEngine::run` instead of multiple
places where calling `ChainSync` methods.

Subject: [PATCH 146/211] wasm-builder: Optimize `rerun-if-changed` logic
 (#2282)

Optimizes the `rerun-if-changed` logic by ignoring `dev-dependencies`
and also not outputting paths. Because outputting paths could lead to
include unwanted crates in the rerun checks.

Subject: [PATCH 147/211] pallet-grandpa: Remove `GRANDPA_AUTHORITIES_KEY`
 (#2181)

Remove the `GRANDPA_AUTHORITIES_KEY` key and its usage. Apparently this
was used in the early days to communicate the grandpa authorities to the
node. However, we have now a runtime api that does this for us. So, this
pull request is moving from the custom managed storage item to a FRAME
managed storage item.

This pr also includes a migration for doing the switch on a running
chain.

Subject: [PATCH 148/211] Adds syntax for marking calls feeless (#1926)

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>,
+ >,
```

### Todo
- [x] Tests
- [x] Docs
- [x] Prdoc

+//! # Skip Feeless Payment Pallet
+//!
+//! This pallet allows runtimes that include it to skip payment of transaction fees for
+//! dispatchables marked by [`#[pallet::feeless_if]`](`macro@
+//! frame_support::pallet_prelude::feeless_if`).
+//!
+//! ## Overview
+//!
+//! It does this by wrapping an existing [`SignedExtension`] implementation (e.g.
+//! [`pallet-transaction-payment`]) and checking if the dispatchable is feeless before applying the
+//! wrapped extension. If the dispatchable is indeed feeless, the extension is skipped and a custom
+//! event is emitted instead. Otherwise, the extension is applied as usual.
+//!
+//!
+//! ## Integration
+//!
+//! This pallet wraps an existing transaction payment pallet. This means you should both pallets
+//! in your `construct_runtime` macro and include this pallet's
+//! [`SignedExtension`] ([`SkipCheckIfFeeless`]) that would accept the existing one as an argument.

Subject: [PATCH 150/211] pallet-xcm: enhance `reserve_transfer_assets` to
 support remote reserves (#1672)

## 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).

Subject: [PATCH 153/211] review-bot: trigger only on review approvals (#2289)

Moved the review event of review-bot to only be triggered in approvals.

Because we only update the required reviews when someone approves, this
will stop the bot from immediately requesting a new review when someone
comments or request changes as they should have been already notified in
the first batch.

Subject: [PATCH 154/211] cumulus-pov-recovery: check pov_hash instead of
 reencoding data (#2287)

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.

Subject: [PATCH 155/211] Fix `ecdsa_bls` verify in BEEFY primitives (#2066)

BEEFY ECDSA signatures are on keccak has of the messages. As such we can
not simply call

`EcdsaBlsPair::verify(signature.as_inner_ref(), msg,
self.as_inner_ref())`

because that invokes ecdsa default verification which perfoms blake2
hash which we don't want.

This bring up the second issue makes: This makes `sign` and `verify`
function in `pair_crypto` useless, at least for BEEFY use case.
Moreover, there is no obvious clean way to generate the signature given
that pair_crypto does not exposes `sign_prehashed`. You could in theory
query the keystore for the pair (could you?), invoke `to_raw` and
re-generate each sub-pair and sign using each. But that sounds extremely
anticlimactic and will be frow upon by auditors . So I appreciate any
alternative suggestion.

Subject: [PATCH 156/211] Fix `expect_pallet` benchmarks not relaying on
 hard-coded `frame_system` dependency version (#2288)

## Problem/Motivation
The benchmark for the `ExpectPallet` XCM instruction uses a hard-coded
version `4.0.0` for the `frame_system` pallet. Unfortunately, this
doesn't work for the `polkadot-fellows/runtimes` repository, where we
use dependencies from `crates.io`, e.g.,
[frame-system::23.0.0.0](https://github.com/polkadot-fellows/runtimes/blob/dd7f86f0d50064481ed0b7c0218494a5cfad997e/relay/kusama/Cargo.toml#L83).

Closes: https://github.com/paritytech/polkadot-sdk/issues/2284

## Solution
This PR fixes the benchmarks that require pallet information and enables
the runtime to provide the correct/custom pallet information. The
default implementation provides `frame_system::Pallet` with index `0`,
where the version is not hard-coded but read from the runtime.


## Local testing

Added log for `T::valid_pallet` to the benchmarks like:
```
let valid_pallet = T::valid_pallet();
log::info!(
	target: "frame::benchmark::pallet",
	"valid_pallet: {}::{}::{}::{}::{}",
	valid_pallet.index,
	valid_pallet.module_name,
	valid_pallet.crate_version.major,
	valid_pallet.crate_version.minor,
	valid_pallet.crate_version.patch,
);
```

Run benchmarks for `westend`:
```
cargo run --bin=polkadot --features=runtime-benchmarks -- benchmark pallet --steps=2 --repeat=1 --extrinsic=* --heap-pages=4096 --json-file=./bench.json --chain=westend-dev --template=./polkadot/xcm/pallet-xcm-benchmarks/template.hbs --pallet=pallet_xcm_benchmarks::generic --output=./polkadot/runtime/westend/src/weights/xcm
```

---

For actual `frame_system` version:
```
[package]
name = "frame-system"
version = "4.0.0-dev"
```

Log dump:
```

Subject: [PATCH 158/211] Add details in `--dev` cli flag documentation (#2305)

add details in `--dev` flag to tell that it disables local peer
discovery

### Context

When adding automated end-to-end tests, we replaced `--dev` by

```
`--chain=dev`, `--force-authoring`, `--rpc-cors=all`, `--alice`, and `--tmp` flags
```

as stated in the command line documentation. But the tests started
failing due to the nodes connecting to each other.

### Fix

This PR includes additional command line documentation to explain more
in detail what `--dev` flag inludes.

Subject: [PATCH 162/211] chainHead: Support multiple hashes for
 `chainHead_unpin` method (#2295)

This PR adds support for multiple hashes being passed to the
`chainHeda_unpin` parameters.

The `hash` parameter is renamed to `hash_or_hashes` per
https://github.com/paritytech/json-rpc-interface-spec/pull/111.

While at it, a new integration test is added to check the unpinning of
multiple hashes. The API is checked against a hash or a vector of
hashes.

Subject: [PATCH 163/211] chainHead: Remove `chainHead_genesis` method (#2296)

The method has been removed from the spec
(https://github.com/paritytech/json-rpc-interface-spec/tree/main/src),
this PR keeps the `chainHead` in sync with that change.

Subject: [PATCH 164/211] Add simple collator election mechanism (#1340)

Fixes https://github.com/paritytech/polkadot-sdk/issues/106

Port of cumulus PR https://github.com/paritytech/cumulus/pull/2960

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

Subject: [PATCH 166/211] chainHead/tests: Fix clippy (#2325)

Remove the genesis hash from tests:
- Clippy was passing on the PR:
https://github.com/paritytech/polkadot-sdk/pull/2296
- Clippy fails on master:
https://gitlab.parity.io/parity/mirrors/polkadot-sdk/-/jobs/4328487

This was a race with merging:
https://github.com/paritytech/polkadot-sdk/pull/2295, which introduced
another test that used the `CHAIN_GENESIS`

Subject: [PATCH 169/211] add NodeFeatures field to HostConfiguration and
 runtime API (#2177)

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

Subject: [PATCH 170/211] Contracts expose pallet-xcm (#1248)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This PR introduces:
- XCM  host functions `xcm_send`, `xcm_execute`
- An Xcm trait into the config. that proxy these functions to to
`pallet_xcm`, or disable their usage by using `()`.
- A mock_network and xcm_test files to test the newly added xcm-related
functions.

Subject: [PATCH 171/211] pallet-xcm: use XcmTeleportFilter for teleported fees
 in reserve transfers (#2322)

Disallow reserve transfers that use teleportable fees if `(origin,
fees)` matches `XcmTeleportFilter`.

Add regression tests for filtering based on `XcmTeleportFilter` for both
`(limited_)reserve_transfer_assets()` and `(limited_)teleport_assets`
extrinsics.

Subject: [PATCH 173/211] [CI] Prepare CI for Merge Queues (#2308)

PR prepares CI to the GitHub Merge Queues. All github actions that were
running in PR adjusted so they can run in the merge queues. Zombienet
jobs will do nothing during PRs but they will run during merge queues.

Jobs that will be skipped during PR:
 - all zombienet jobs
 - all publish docker jobs

Jobs that will be skipped during merge queue:
 - check-labels
 - check-prdoc
 - pr-custom-review
 - review trigger

Subject: [PATCH 174/211] Identity Deposits Relay to Parachain Migration
 (#1814)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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.

TODO:

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

+//! This pallet is designed to go into a source chain and destination chain to migrate data. The
+//! design motivations are:
+//!
+//! - Call some function on the source chain that executes some migration (clearing state,
+//!   forwarding an XCM program).
+//! - Call some function (probably from an XCM program) on the destination chain.
+//! - Avoid cluttering the source pallet with new dispatchables that are unrelated to its
+//!   functionality and only used for migration.
+//!
+//! After the migration is complete, the pallet may be removed from both chains' runtimes as well as
+//! the `polkadot-runtime-common` crate.

Subject: [PATCH 175/211] Add `collectives-westend` and `glutton-westend`
 runtimes (#2024)

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

+//! The module defines the following on-chain functionality of the Ambassador Program:
+//!
+//! - Managed set of program members, where every member has a [rank](ranks)
+//! (via [AmbassadorCollective](pallet_ranked_collective)).
+//! - Referendum functionality for the program members to propose, vote on, and execute
+//! proposals on behalf of the members of a certain [rank](Origin)
+//! (via [AmbassadorReferenda](pallet_referenda)).
+//! - Managed content (charter, announcements) (via [pallet_collective_content]).
+//! - Promotion and demotion periods, register of members' activity, and rank based salaries
+//! (via [AmbassadorCore](pallet_core_fellowship)).
+//! - Members' salaries (via [AmbassadorSalary](pallet_salary), requiring a member to be
+//! imported or inducted into [AmbassadorCore](pallet_core_fellowship)).

+//! # Collectives Parachain
+//!
+//! This parachain is for collectives that serve the Westend network.
+//! Each collective is defined by a specialized (possibly instanced) pallet.
+//!
+//! ### Governance
+//!
+//! As a system parachain, Collectives defers its governance (namely, its `Root` origin), to
+//! its Relay Chain parent, Westend.
+//!
+//! ### Collator Selection
+//!
+//! Collectives uses `pallet-collator-selection`, a simple first-come-first-served registration
+//! system where collators can reserve a small bond to join the block producer set. There is no
+//! slashing. Collective members are generally expected to run collators.

+//! # Glutton Westend Runtime
+//!
+//! The purpose of the Glutton parachain is to do stress testing on the Kusama
+//! network. This runtime targets the Westend runtime to allow development
+//! separate to the Kusama runtime.
+//!
+//! There may be multiple instances of the Glutton parachain deployed and
+//! connected to its parent relay chain.
+//!
+//! These parachains are not holding any real value. Their purpose is to stress
+//! test the network.
+//!
+//! ### Governance
+//!
+//! Glutton defers its governance (namely, its `Root` origin), to its Relay
+//! Chain parent, Kusama (or Westend for development purposes).
+//!
+//! ### XCM
+//!
+//! Since the main goal of Glutton is solely stress testing, the parachain will
+//! only be able receive XCM messages from the Relay Chain via DMP. This way the
+//! Glutton parachains will be able to listen for upgrades that are coming from
+//! the Relay chain.

From 824b782390b16b433df89dd3ff451ea3f0ea03a1 Mon Sep 17 00:00:00 2001

Subject: [PATCH 176/211] xcm: SovereignPaidRemoteExporter: remove unused
 RefundSurplus instruction (#2312)

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.

Subject: [PATCH 177/211] [testnet] Remove Wococo stuff from
 BridgeHubRococo/AssetHubRococo (#2300)

Rococo<>Wococo bridge is replaced by Rococo<Westend bridge, so this PR
removes unneeded code.

- [x] update bridges subtree after
https://github.com/paritytech/parity-bridges-common/pull/2692

 ## Running the Bridge
 
-To run the Bridge you need to be able to connect the bridge relay node to the RPC interface of nodes on each side of the
-bridge (source and target chain).
-
-There are 2 ways to run the bridge, described below:
-
-- building & running from source: with this option, you'll be able to run the bridge between two standalone chains that
-are running GRANDPA finality gadget to achieve finality;
-
-- running a Docker Compose setup: this is a recommended option, where you'll see bridges with parachains, complex relays
-and more.
-
-### Using the Source
-
-First you'll need to build the bridge nodes and relay. This can be done as follows:
-
-```bash
-# In `parity-bridges-common` folder
-cargo build -p rialto-bridge-node
-cargo build -p millau-bridge-node
-cargo build -p substrate-relay
-```
-
-### Running a Dev network
-
-We will launch a dev network to demonstrate how to relay a message between two Substrate based chains (named Rialto and
-Millau).
-
-To do this we will need two nodes, two relayers which will relay headers, and two relayers which will relay messages.
-
-#### Running from local scripts
-
-To run a simple dev network you can use the scripts located in the [`deployments/local-scripts`
-folder](./deployments/local-scripts).
-
-First, we must run the two Substrate nodes.
-
-```bash
-# In `parity-bridges-common` folder
-./deployments/local-scripts/run-rialto-node.sh
-./deployments/local-scripts/run-millau-node.sh
-```
-
-After the nodes are up we can run the header relayers.
-
-```bash
-./deployments/local-scripts/relay-millau-to-rialto.sh
-./deployments/local-scripts/relay-rialto-to-millau.sh
-```
-
-At this point you should see the relayer submitting headers from the Millau Substrate chain to the Rialto Substrate
-chain.
-
-```
-# Header Relayer Logs
-[Millau_to_Rialto_Sync] [date] DEBUG bridge Going to submit finality proof of Millau header #147 to Rialto
-[...] [date] INFO bridge Synced 147 of 147 headers
-[...] [date] DEBUG bridge Going to submit finality proof of Millau header #148 to Rialto
-[...] [date] INFO bridge Synced 148 of 149 headers
-```
-
-Finally, we can run the message relayers.
-
-```bash
-./deployments/local-scripts/relay-messages-millau-to-rialto.sh
-./deployments/local-scripts/relay-messages-rialto-to-millau.sh
-```
-
-You will also see the message lane relayers listening for new messages.
-
-```
-# Message Relayer Logs
-[Millau_to_Rialto_MessageLane_00000000] [date] DEBUG bridge Asking Millau::ReceivingConfirmationsDelivery about best message nonces
-[...] [date] INFO bridge Synced Some(2) of Some(3) nonces in Millau::MessagesDelivery -> Rialto::MessagesDelivery race
-[...] [date] DEBUG bridge Asking Millau::MessagesDelivery about message nonces
-[...] [date] DEBUG bridge Received best nonces from Millau::ReceivingConfirmationsDelivery: TargetClientNonces {
-	  latest_nonce: 0, nonces_data: () }
-[...] [date] DEBUG bridge Asking Millau::ReceivingConfirmationsDelivery about finalized message nonces
-[...] [date] DEBUG bridge Received finalized nonces from Millau::ReceivingConfirmationsDelivery: TargetClientNonces {
-	  latest_nonce: 0, nonces_data: () }
-[...] [date] DEBUG bridge Received nonces from Millau::MessagesDelivery: SourceClientNonces { new_nonces: {}, confirmed_nonce: Some(0) }
-[...] [date] DEBUG bridge Asking Millau node about its state
-[...] [date] DEBUG bridge Received state from Millau node: ClientState { best_self: HeaderId(1593, 0xacac***), best_finalized_self:
-       HeaderId(1590, 0x0be81d...), best_finalized_peer_at_best_self: HeaderId(0, 0xdcdd89...) }
-```
-
-To send a message see the ["How to send a message" section](#how-to-send-a-message).
-
-### How to send a message
-
-In this section we'll show you how to quickly send a bridge message. The message is just an encoded XCM `Trap(43)`
-message.
-
-```bash
-# In `parity-bridges-common` folder
-./scripts/send-message-from-millau-rialto.sh
-```
-
-After sending a message you will see the following logs showing a message was successfully sent:
-
-```
-INFO bridge Sending message to Rialto. Size: 11.
-TRACE bridge Sent transaction to Millau node: 0x5e68...
-```
-
-And at the Rialto node logs you'll something like this:
-
-```
-... runtime::bridge-messages: Received messages: total=1, valid=1. Weight used: Weight(ref_time: 1215065371, proof_size:
-    48559)/Weight(ref_time: 1215065371, proof_size: 54703).
-```
-
-It means that the message has been delivered and dispatched. Message may be dispatched with an error, though - the goal
-of our test bridge is to ensure that messages are successfully delivered and all involved components are working.
-
-## Full Network Docker Compose Setup
-
-For a more sophisticated deployment which includes bidirectional header sync, message passing, monitoring dashboards,
-etc. see the [Deployments README](./deployments/README.md).
-
-You should note that you can find images for all the bridge components published on [Docker
-Hub](https://hub.docker.com/u/paritytech).
-
-To run a Rialto node for example, you can use the following command:
-
-```bash
-docker run -p 30333:30333 -p 9933:9933 -p 9944:9944 \
-  -it paritytech/rialto-bridge-node --dev --tmp \
-  --rpc-cors=all --unsafe-rpc-external
-```
-
-## Community
-
-Main hangout for the community is [Element](https://element.io/) (formerly Riot). Element is a chat server like, for
-example, Discord. Most discussions around Polkadot and Substrate happen in various Element "rooms" (channels). So,
-joining Element might be a good idea, anyway.
-
-If you are interested in information exchange and development of Polkadot related bridges please feel free to join the
-[Polkadot Bridges](https://app.element.io/#/room/#bridges:web3.foundation) Element channel.
-
-The [Substrate Technical](https://app.element.io/#/room/#substrate-technical:matrix.org) Element channel is most suited
-for discussions regarding Substrate itself.
+Apart from live Rococo <> Westend bridge, you may spin up local networks and test see how it works locally. More
+details may be found in
+[this document](https://github.com/paritytech/polkadot-sdk/tree/master//cumulus/parachains/runtimes/bridge-hubs/README.md).

Subject: [PATCH 178/211] frame-system: Add `last_runtime_upgrade_spec_version`
 (#2351)

Adds a function for querying the last runtime upgrade spec version. This
can be useful for when writing runtime level migrations to ensure that
they are not executed multiple times. An example would be a session key
migration.

Subject: [PATCH 180/211] westend: remove SessionKeys migration already applied
 on-chain (#2363)

Westend now successfully updated to `spec: 103000`, we **have to
remove** the session keys migration before the next release as it
doesn't gracefully handle reapplying it.

Subject: [PATCH 183/211] add pallet nomination-pools versioned migration to
 kitchensink (#2167)

The versioned migrations are already there in pallet nomination-pools:

https://github.com/paritytech/polkadot-sdk/blob/f6ee4781f633f0f89598f7b230595afe401da8dc/substrate/frame/nomination-pools/src/migration.rs#L27-L48

Just updating the kitchensink runtime to point to them.

This is also nice because it points the dev to an example of how to use
`VersionedMigration`.

Subject: [PATCH 186/211] [NPoS] Check if staker is exposed in paged exposure
 storage entries (#2369)

Addresses a bug caused by
https://github.com/paritytech/polkadot-sdk/pull/1189. The changes are
still not released yet, so would like to push the fix soon so it can go
together with the release of the above PR.

`fast_unstake` checks if a staker is exposed in an era. However, this fn
is still returning whether the staker is exposed based on the old
storage item. This PR fixes that by looking in both old and new exposure
storages.

Also adds some integrity tests for paged exposures.

Subject: [PATCH 188/211] crypto: `lazy_static` removed, light parser for
 address URI added (#2250)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The `lazy_static` package does not work well in `no-std`: it requires
`spin_no_std` feature, which also will propagate into `std` if enabled.
This is not what we want.

This PR provides simple address uri parser which allows to get rid of
_regex_ which was used to parse the address uri, what in turns allows to
remove lazy_static.

Three regular expressions

the parser which unifies all of them.

The new parser does not support Unicode, it is ASCII only.

Subject: [PATCH 190/211] Do not panic if the `fdlimit` call to increase the
 file descriptor limit fails (#2155)

# Description

Sometimes changing file descriptor limits is not allowed, but there is
no need to crash the node if/when this happens. Since `fdlimit`'s author
decided to use panics instead of returning `Result`, we need to catch
it.

# Checklist

- [x] My PR includes a detailed description as outlined in the
"Description" section above
- [ ] My PR follows the [labeling requirements](CONTRIBUTING.md#Process)
of this project (at minimum one label for `T`
  required)
- [ ] I have made corresponding changes to the documentation (if
applicable)
- [ ] I have added tests that prove my fix is effective or that my
feature works (if applicable)

Subject: [PATCH 191/211] Relax `force_default_xcm_version` for testnet system
 parachains (#2385)

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

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.

Subject: [PATCH 199/211] remove retry from backers on failed candidate
 validation (#2182)

Hey guys, as discussed I've changed the name to a more general one
`PvfExecKind`, is this good or too general?
Creating this as a draft, I still have to fix the tests.

Closes #1585

Kusama address: FkB6QEo8VnV3oifugNj5NeVG3Mvq1zFbrUu4P5YwRoe5mQN

Subject: [PATCH 201/211] `chain-spec-builder`: cleanup (#2174)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This PR removes:
-  `New`, `Generate`, `Edit` commands,
- `kitchensink` dependency
from the `chain-spec-builder` util.

New `convert-to-raw`, `update-code` commands were added.

Additionally renames the `runtime` command (which was added in #1256) to
`create`.

+//! storage (`-s`) version of chain spec:
+//! ```text
+//! chain-spec-builder create -s -r runtime.wasm patch patch.json
+//! ```
+//!

+//!
+//! ##### Generate raw storage chain spec using full genesis config.
+//!
+//! Build the chain spec using provided full genesis config json file. No defaults will be used:
+//! ```text
+//! chain-spec-builder create -s -r runtime.wasm full full-genesis-config.json

+//! ##### Generate human readable chain spec using provided full genesis config.
+//! ```text

Subject: [PATCH 205/211] cumulus-consensus-common: block import:
 `delayed_best_block` flag added (#2001)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

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

Subject: [PATCH 206/211] Different XCM builders, default one requires fee
 payment (#2253)

Adding on top of the new builder pattern for creating XCM programs, I'm
adding some more APIs:

```rust
let paying_fees: Xcm<()> = Xcm::builder() // Only allow paying for fees
  .withdraw_asset() // First instruction has to load the holding register
  .buy_execution() // Second instruction has to be `buy_execution`
  .build();

let paying_fees_invalid: Xcm<()> = Xcm::builder()
  .withdraw_asset()
  .build(); // Invalid, need to pay for fees

let not_paying_fees: Xcm<()> = Xcm::builder_unpaid()
  .unpaid_execution() // Needed
  .withdraw_asset()
  .deposit_asset()
  .build();

let all_goes: Xcm<()> = Xcm::builder_unsafe() // You can do anything
  .withdraw_asset()
  .deposit_asset()
  .build();
```

The invalid bits are because the methods don't even exist on the types
that you'd want to call them on.

+title: Different builder pattern constructors for XCM
+
+doc:
+  - audience: Core Dev
+    description: |
+      The `builder()` constructor for XCM programs now only allows building messages that pay for fees,
+      i.e. messages that would pass the `AllowTopLevelPaidExecutionFrom` barrier.
+      Another constructor, `builder_unpaid()` requires an explicit `UnpaidExecution` instruction before
+      anything else.
+      For building messages without any restriction, `builder_unsafe` can be used.
+      This has been named like that since in general the other two should be used instead, but it's okay
+      to use it for teaching purposes or for experimenting.

Subject: [PATCH 207/211] added action to pass review bot on merge queue
 (#2414)

This action will trigger when a merge queue is created and will add a
positive status check under the `review-bot` account, allowing the PR to
pass the required check for the merge.

Subject: [PATCH 209/211] cumulus-test-service: block import fix (#2430)

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.

Subject: [PATCH 210/211] Deprecate `RewardDestination::Controller` (#2380)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Deprecates `RewardDestination::Controller` variant.

- [x] `RewardDestination::Controller` annotated with `#[deprecated]`.
- [x] `Controller` variant is now handled the same way as `Stash` in
`payout_stakers`.
- [x] `set_payee` errors if `RewardDestination::Controller` is provided.
- [x] Added `update_payee` call to lazily migrate
`RewardDestination::Controller` `Payee` storage entries to
`RewardDestination::Account(controller)` .
- [x] `payout_stakers_dead_controller` has been removed from benches &
weights - was not used.
- [x] Tests no longer use `RewardDestination::Controller`.
