Introduce subsystem benchmarking tool (#2528) · 8a6e9ef1

Andrei Sandu authored Dec 14, 2023

This tool makes it easy to run parachain consensus stress/performance
testing on your development machine or in CI.

## Motivation
The parachain consensus node implementation spans across many modules
which we call subsystems. Each subsystem is responsible for a small part
of logic of the parachain consensus pipeline, but in general the most
load and performance issues are localized in just a few core subsystems
like `availability-recovery`, `approval-voting` or
`dispute-coordinator`. In the absence of such a tool, we would run large
test nets to load/stress test these parts of the system. Setting up and
making sense of the amount of data produced by such a large test is very
expensive, hard to orchestrate and is a huge development time sink.

## PR contents
- CLI tool 
- Data Availability Read test
- reusable mockups and components needed so far
- Documentation on how to get started

### Data Availability Read test

An overseer is built with using a real `availability-recovery` susbsytem
instance while dependent subsystems like `av-store`, `network-bridge`
and `runtime-api` are mocked. The network bridge will emulate all the
network peers and their answering to requests.

The test is going to be run for a number of blocks. For each block it
will generate send a “RecoverAvailableData” request for an arbitrary
number of candidates. We wait for the subsystem to respond to all
requests before moving to the next block.
At the same time we collect the usual subsystem metrics and task CPU
metrics and show some nice progress reports while running.

### Here is how the CLI looks like:

```

Tests for BridgeHub(s) <> remote GRANDPA chain (#2692) · 9ecb2d33

Svyatoslav Nikolsky authored Dec 13, 2023

So far the `bridge-hub-test-utils` contained a tests set for testing
BridgeHub runtime that is bridging with the remote **parachain**. But we
have https://github.com/paritytech/polkadot-sdk/pull/2540 coming, which
would add Rococo <> Bulletin chain bridge (where Bulletin = standalone
chain that is using GRANDPA finality). Then it'll be expanded to
Polkadot BH as well.

So this PR adds the same set of tests to the `bridge-hub-test-utils`,
but for the case when remote chain is the chain with GRANDPA finality.
There's a lot of changes in this PR - I'll describe some:
- I've added `BasicParachainRuntime` trait to decrease number of lines
we need to add to `where` clause. Could revert, but imo it is useful;
- `cumulus/parachains/runtimes/bridge-hubs/test-utils/src/test_data` is
a submodule for generating test data for the test sets.
`from_parachain.rs` is used in tests for the case when remote chain is a
parachain, `from_grandpa_chain.rs` - for the bridges with remote GRANDPA
chains. `mod.rs` has some code, shared by both types of tests;
- `cumulus/parachains/runtimes/bridge-hubs/test-utils/src/test_data` is
a submodule with all test cases. The `mod.rs` has tests, suitable for
all cases. There's also `wth_parachain.rs` and `with_grandpa_chain.rs`
with the same meaning as above;
- I've merged the "core" code of two previous tests -
`relayed_incoming_message_works` and `complex_relay_extrinsic_works`
into one single `relayed_incoming_message_works` test. So now we are
always constructing extrinsics and are dispatching them using executive
module (meaning all signed extensions are also tested).

New test set is used here:
https://github.com/paritytech/polkadot-sdk/pull/2540. Once this PR is
merged, I'll merge that other PR with master to remove duplicate
changes.

I'm also planning to cleanup generic constraints + remove some
unnecessary assumptions about used chains in a follow-up PRs. But for
now I think this PR has enough changes, so don't want to complicate it
even more.

---

Breaking changes for the code that have used those tests before:
- the `construct_and_apply_extrinsic` callback now accepts the
`RuntimeCall` instead of the `pallet_utility::Call`;
- the `construct_and_apply_extrinsic` now may be called multiple times
for the single test, so make sure the `frame_system::CheckNonce` is
correctly constructed;
- all previous tests have been moved from
`bridge_hub_test_utils::test_cases` to
`bridge_hub_test_utils::test_cases::from_parachain` module;
- there are several changes in test arguments - please refer to
https://github.com/paritytech/polkadot-sdk/compare/sv-tests-for-bridge-with-remote-grandpa-chain?expand=1#diff-79a28d4d3e1749050341c2424f00c4c139825b1a20937767f83e58b95166735c

Rename `ExportGenesisStateCommand` to `ExportGenesisHeadCommand` and make it... · 8683bbee

Joshy Orndorff authored Dec 13, 2023


Rename `ExportGenesisStateCommand` to `ExportGenesisHeadCommand` and make it respect custom genesis block builders (#2331)

Closes #2326.

This PR both fixes a logic bug and replaces an incorrect name.

## Bug Fix: Respecting custom genesis builder

Prior to this PR the standard logic for creating a genesis block was
repeated inside of cumulus. This PR removes that duplicated logic, and
calls into the proper `BuildGenesisBlock` implementation.

One consequence is that if the genesis block has already been
initialized, it will not be re-created, but rather read from the
database like it is for other node invocations. So you need to watch out
for old unpurged data during the development process. Offchain tools may
need to be updated accordingly. I've already filed
https://github.com/paritytech/zombienet/issues/1519

## Rename: It doesn't export state. It exports head data.

The name export-genesis-state was always wrong, nad it's never too late
to right a wrong. I've changed the name of the struct to
`ExportGenesisHeadCommand`.

There is still the question of what to do with individual nodes' public
CLIs. I have updated the parachain template to a reasonable default that
preserves compatibility with tools that will expect
`export-genesis-state` to still work. And I've chosen not to modify the
public CLIs of any other nodes in the repo. I'll leave it up to their
individual owners/maintains to decide whether that is appropriate.

Ensure xcm versions over bridge (on sending chains) (#2481) · 575b8f8d

Branislav Kontur authored Dec 12, 2023

## Summary

This pull request proposes a solution for improved control of the
versioned XCM flow over the bridge (across different consensus chains)
and resolves the situation where the sending chain/consensus has already
migrated to a higher XCM version than the receiving chain/consensus.

## Problem/Motivation

The current flow over the bridge involves a transfer from AssetHubRococo
(AHR) to BridgeHubRococo (BHR) to BridgeHubWestend (BHW) and finally to
AssetHubWestend (AHW), beginning with a reserve-backed transfer on AHR.

In this process:
1. AHR sends XCM `ExportMessage` through `XcmpQueue`, incorporating XCM
version checks using the `WrapVersion` feature, influenced by
`pallet_xcm::SupportedVersion` (managed by
`pallet_xcm::force_xcm_version` or version discovery).

2. BHR handles the `ExportMessage` instruction, utilizing the latest XCM
version. The `HaulBlobExporter` converts the inner XCM to
[`VersionedXcm::from`](https://github.com/paritytech/polkadot-sdk/blob/63ac2471/polkadot/xcm/xcm-builder/src/universal_exports.rs#L465-L467),
also using the latest XCM version.

However, challenges arise:
- Incompatibility when BHW uses a different version than BHR. For
instance, if BHR migrates to **XCMv4** while BHW remains on **XCMv3**,
BHR's `VersionedXcm::from` uses `VersionedXcm::V4` variant, causing
encoding issues for BHW.
  ```
	/// Just a simulation of possible error, which could happen on BHW
	/// (this code is based on actual master without XCMv4)
	let encoded = hex_literal::hex!("0400");
	println!("{:?}", VersionedXcm::<()>::decode(&mut &encoded[..]));

Err(Error { cause: None, desc: "Could not decode `VersionedXcm`, variant
doesn't exist" })
  ``` 
- Similar compatibility issues exist between AHR and AHW.

## Solution

This pull request introduces the following solutions:

1. **New trait `CheckVersion`** - added to the `xcm` module and exposing
`pallet_xcm::SupportedVersion`. This enhancement allows checking the
actual XCM version for desired destinations outside of the `pallet_xcm`
module.

2. **Version Check in `HaulBlobExporter`** uses `CheckVersion` to check
known/configured destination versions, ensuring compatibility. For
example, in the scenario mentioned, BHR can store the version `3` for
BHW. If BHR is on XCMv4, it will attempt to downgrade the message to
version `3` instead of using the latest version `4`.

3. **Version Check in `pallet-xcm-bridge-hub-router`** - this check
ensures compatibility with the real destination's XCM version,
preventing the unnecessary sending of messages to the local bridge hub
if versions are incompatible.

These additions aim to improve the control and compatibility of XCM
flows over the bridge and addressing issues related to version
mismatches.

## Possible alternative solution

_(More investigation is needed, and at the very least, it should extend
to XCMv4/5. If this proves to be a viable option, I can open an RFC for
XCM.)._

Add the `XcmVersion` attribute to the `ExportMessage` so that the
sending chain can determine, based on what is stored in
`pallet_xcm::SupportedVersion`, the version the destination is using.
This way, we may not need to handle the version in `HaulBlobExporter`.

```
ExportMessage {
	network: NetworkId,
	destination: InteriorMultiLocation,
	xcm: Xcm<()>
	destination_xcm_version: Version, // <- new attritbute
},
```

```
pub trait ExportXcm {
        fn validate(
		network: NetworkId,
		channel: u32,
		universal_source: &mut Option<InteriorMultiLocation>,
		destination: &mut Option<InteriorMultiLocation>,
		message: &mut Option<Xcm<()>>,
                destination_xcm_version: Version, , // <- new attritbute
	) -> SendResult<Self::Ticket>;
```

## Future Directions

This PR does not fix version discovery over bridge, further
investigation will be conducted here:
https://github.com/paritytech/polkadot-sdk/issues/2417.

## TODO

- [x] `pallet_xcm` mock for tests uses hard-coded XCM version `2` -
change to 3 or lastest?
- [x] fix `pallet-xcm-bridge-hub-router`
- [x] fix HaulBlobExporter with version determination
[here](https://github.com/paritytech/polkadot-sdk/blob/2183669d/polkadot/xcm/xcm-builder/src/universal_exports.rs#L465)
- [x] add unit-tests to the runtimes
- [x] run benchmarks for `ExportMessage`
- [x] extend local run scripts about `force_xcm_version(dest, version)`
- [ ] when merged, prepare governance calls for Rococo/Westend
- [ ] add PRDoc

Changelogs local generation (#1411) · 42a3afba

Chevdor authored Dec 12, 2023



This PR introduces a script and some templates to use the prdoc involved
in a release and build:
- the changelog
- a simple draft of audience documentation

Since the prdoc presence was enforced in the middle of the version
1.5.0, not all PRs did come with a `prdoc` file.
This PR creates all the missing `prdoc` files with some minimum content
allowing to properly generate the changelog.
The generated content is **not** suitable for the audience
documentation.

The audience documentation will be possible with the next version, when
all PR come with a proper `prdoc`.

## Assumptions

- the prdoc files for release `vX.Y.Z` have been moved under
`prdoc/X.Y.Z`
- the changelog requires for now for the prdoc files to contain author +
topic. Thos fields are optional.

The build script can  be called as:
```
VERSION=X.Y.Z ./scripts/release/build-changelogs.sh
```

`keyring`: remove `lazy_static` public keys hash maps (#2387) · f6548aee

Michal Kucharczyk authored Dec 11, 2023



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 removes public/private key hash-maps and replaces them with
simple static byte arrays.

`&T` versions of `AsRef/Deref/From` traits implementation were removed.

Little const helper for converting hex strings into array during compile
time was also added. (somewhat similar to _hex_literal_).

Westend: Fellowship Treasury (#2532) · da40d97a

Muharem Ismailov authored Dec 08, 2023



Treasury Pallet Instance for the Fellowship in Westend Collectives.

In this update, we present a Treasury Pallet Instance that is under the
control of the Fellowship body, with oversight from the Root and
Treasurer origins. Here's how it is governed:
- the Root origin have the authority to reject or approve spend
proposals, with no amount limit for approvals.
- the Treasurer origin have the authority to reject or approve spend
proposals, with approval limits of up to 10,000,000 DOT.
- Voice of all Fellows ranked at 3 or above can reject or approve spend
proposals, with a maximum approval limit of 10,000 DOT.
- Voice of Fellows ranked at 4 or above can also reject or approve spend
proposals, with a maximum approval limit of 10,000,000 DOT.

Additionally, we introduce the Asset Rate Pallet Instance to establish
conversion rates from asset A to B. This is used to determine if a
proposed spend amount involving a non-native asset is permissible by the
commanding origin. The rates can be set up by the Root, Treasurer
origins, or Voice of all Fellows.

```rust
// NOTE: this enum is optional and is auto-generated by the other macros if not present
#[pallet::task]
pub enum Task<T: Config> {
    AddNumberIntoTotal {
        i: u32,
    }
}

/// Some running total.
#[pallet::storage]
pub(super) type Total<T: Config<I>, I: 'static = ()> =
StorageValue<_, (u32, u32), ValueQuery>;

/// Numbers to be added into the total.
#[pallet::storage]
pub(super) type Numbers<T: Config<I>, I: 'static = ()> =
StorageMap<_, Twox64Concat, u32, u32, OptionQuery>;

#[pallet::tasks_experimental]
impl<T: Config<I>, I: 'static> Pallet<T, I> {
	/// Add a pair of numbers into the totals and remove them.
	#[pallet::task_list(Numbers::<T, I>::iter_keys())]
	#[pallet::task_condition(|i| Numbers::<T, I>::contains_key(i))]
	#[pallet::task_index(0)]
	pub fn add_number_into_total(i: u32) -> DispatchResult {
		let v = Numbers::<T, I>::take(i).ok_or(Error::<T, I>::NotFound)?;
		Total::<T, I>::mutate(|(total_keys, total_values)| {
			*total_keys += i;
			*total_values += v;
		});
		Ok(())
	}
}

Remove `testnets-common` (#2620) · 814b938d

Dónal Murray authored Dec 07, 2023

`testnets-common` was introduced recently to start to separate testnet
parachain configurations from those of Polkadot and Kusama.

The `locks-review` and `polkadot-review` requirements are removed from
`parachains-common` in
https://github.com/paritytech/polkadot-sdk/pull/2564 and there are
[plans](https://github.com/paritytech/polkadot-sdk/pull/2564#discussion_r1410882115)
to move the Polkadot and Kusama contents of that package to the
fellowship, `testnets-common` is no longer needed.

This PR removes the crate and replaces uses of it in
`collectives-westend`, the only place it is currently used.

[FRAME] Make MQ pallet re-entrancy safe (#2356) · 7e7fe990

Oliver Tale-Yazdi authored Dec 07, 2023



Closes https://github.com/paritytech/polkadot-sdk/issues/2319

Changes:
- Ensure that only `enqueue_message(s)` is callable from within the
message processor. This prevents messed up storage that can currently
happen when the pallet is called into recursively.
- Use `H256` instead of `[u8; 32]` for clearer API.

## Details

The re-entracy check is done with the `environmental` crate by adding a
`with_service_mutex(f)` function that runs the closure exclusively. This
works since the MQ pallet is not instantiable.

Added AllSiblingSystemParachains matcher to be used at a parachain level (#2422) · 0b3d0677

Svyatoslav Nikolsky authored Dec 07, 2023



As suggested in this thread:
https://github.com/polkadot-fellows/runtimes/pull/87#discussion_r1400237122

We already have the `IsChildSystemParachain`, which may be used at relay
chain, but it can't be used at a parachain level. So let's use
`AllSiblingSystemParachains` for that. I was thinking about
`AllSystemParachains`, but it may cause wrong impression that it can be
used at a relay chain level.

pallet-xcm: add new flexible `transfer_assets()` call/extrinsic (#2388) · e7651cf4

Adrian Catangiu authored Dec 06, 2023

# Motivation (+testing)

### Enable easy `ForeignAssets` transfers using `pallet-xcm` 

We had just previously added capabilities to teleport fees during
reserve-based transfers, but what about reserve-transferring fees when
needing to teleport some non-fee asset?

This PR aligns everything under either explicit reserve-transfer,
explicit teleport, or this new flexible `transfer_assets()` which can
mix and match as needed with fewer artificial constraints imposed to the
user.

This will enable, for example, a (non-system) parachain to teleport
their `ForeignAssets` assets to AssetHub while using DOT to pay fees.
(the assets are teleported - as foreign assets should from their owner
chain - while DOT used for fees can only be reserve-based transferred
between said parachain and AssetHub).

Added `xcm-emulator` tests for this scenario ^.

# Description

Reverts `(limited_)reserve_transfer_assets` to only allow reserve-based
transfers for all `assets` including fees.

Similarly `(limited_)teleport_assets` only allows teleports for all
`assets` including fees.
    
For complex combinations of asset transfers where assets and fees may
have different reserves or different reserve/teleport trust
configurations, users can use the newly added `transfer_assets()`
extrinsic which is more flexible in allowing more complex scenarios.

`assets` (excluding `fees`) must have same reserve location or otherwise
be teleportable to `dest`.
No limitations imposed on `fees`.

- for local reserve: transfer assets to sovereign account of destination
chain and forward a notification XCM to `dest` to mint and deposit
reserve-based assets to `beneficiary`.
- for destination reserve: burn local assets and forward a notification
to `dest` chain to withdraw the reserve assets from this chain's
sovereign account and deposit them to `beneficiary`.
- for remote reserve: burn local assets, forward XCM to reserve chain to
move reserves from this chain's SA to `dest` chain's SA, and forward
another XCM to `dest` to mint and deposit reserve-based assets to
`beneficiary`.
- for teleports: burn local assets and forward XCM to `dest` chain to
mint/teleport assets and deposit them to `beneficiary`.

## Review notes

Only around 500 lines are prod code (see `pallet_xcm/src/lib.rs`), the
rest of the PR is new tests and improving existing tests.

Sassafras Consensus Pallet (#1577) · 095f4bd9

Davide Galassi authored Dec 01, 2023



This PR introduces the pallet for Sassafras consensus.

## Non Goals

The pallet delivers only the bare-bones and doesn't deliver support for
auxiliary functionalities such as equivocation report and support for
epoch change via session pallet.

These functionalities were drafted in the [main
PR](https://github.com/paritytech/polkadot-sdk/pull/1336), but IMO is
better to introduce this auxiliary stuff in a follow up PR and after
client code.

## Potential follow ups

In gossip-support, we shuffled the list of authorities using the
`rand::seq::SliceRandom::shuffle`. This function's behavior is
unspecified beyond being `O(n)` and could change in the future, leading
to network issues between nodes using different shuffling algorithms. In
practice, the implementation was a Fisher-Yates shuffle. This PR
replaces the call with a re-implementation of Fisher-Yates and adds a
test to ensure the behavior is the same between the two at the moment.

PoV Reclaim (Clawback) Node Side (#1462) · 9a650c46

Sebastian Kunert authored Nov 30, 2023

This PR provides the infrastructure for the pov-reclaim mechanism
discussed in #209. The goal is to provide the current proof size to the
runtime so it can be used to reclaim storage weight.

## New Host Function
- A new host function is provided
[here](https://github.com/skunert/polkadot-sdk/blob/5b317fda

/cumulus/primitives/pov-reclaim/src/lib.rs#L23).
It returns the size of the current proof size to the runtime. If
recording is not enabled, it returns 0.

## Implementation Overview
- Implement option to enable proof recording during import in the
client. This is currently enabled for `polkadot-parachain`,
`parachain-template` and the cumulus test node.
- Make the proof recorder ready for no-std. It was previously only
enabled for std environments, but we need to record the proof size in
`validate_block` too.
- Provide a recorder implementation that only the records the size of
incoming nodes and does not store the nodes itself.
- Fix benchmarks that were broken by async backing changes
- Provide new externalities extension that is registered by default if
proof recording is enabled.
- I think we should discuss the naming, pov-reclaim was more intuitive
to me, but we could also go with clawback like in the issue.

## Impact of proof recording during import
With proof recording: 6.3058 Kelem/s
Without proof recording: 6.3427 Kelem/s

The measured impact on the importing performance is quite low on my
machine using the block import benchmark. With proof recording I am
seeing a performance hit of 0.585%.

Introduce Polkadot-Sdk `developer_hub` (#2102) · eaf1bc56

Kian Paimani authored Nov 30, 2023



This PR introduces the new crate `developer_hub` into the polkadot-sdk
repo. The vision for the developer-hub crate is detailed in [this
document](https://docs.google.com/document/d/1XLLkFNE8v8HLvZpI2rzsa8N2IN1FcKntc8q-Sc4xBAk/edit?usp=sharing).

<img width="1128" alt="Screenshot 2023-11-02 at 10 45 48"
src="https://github.com/paritytech/polkadot-sdk/assets/5588131/1e12b60f-fef5-42c4-8503-a3ba234077c3">


Other than adding the new crate, it also does the following: 

* Remove the `substrate` crate, as there is now a unique umbrella crate
for multiple things in `developer_hub::polkadot_sdk`.
* (backport candidate) A minor change to `frame-support` macros that
allows `T::RuntimeOrigin` to also be acceptable as the origin type.
* (backport candidate) A minor change to `frame-system` that allows us
to deposit events at genesis because now the real genesis config is
generated via wasm, and we can safely assume `cfg!(feature = "std")`
means only testing. related to #62.
* (backport candidate) Introduces a small `read_events_for_pallet` to
`frame_system` for easier event reading in tests.
* From https://github.com/paritytech/polkadot-sdk-docs/issues/31, it
takes action on improving the `pallet::call` docs.
* From https://github.com/paritytech/polkadot-sdk-docs/issues/31, it
takes action on improving the `UncheckedExtrinsic` docs.

## Way Forward

First, a version of this is deployed temporarily
[here](https://blog.kianenigma.nl/polkadot-sdk/developer_hub/index.html).
I will keep it up to date on a daily basis.

### This Pull Request

I see two ways forward: 

1. We acknowledge that everything in `developer-hub` is going to be WIP,
and merge this asap. We should not yet use links to this crate anywhere.
2. We make this be the feature branch, make PRs against this, and either
gradually backport it, or only merge to master once it is done.

I am personally in favor of option 1. If we stick to option 2, we need a
better way to deploy a staging version of this to gh-pages.

### Issue Tracking

The main issues related to the future of `developer_hub` are: 

- https://github.com/paritytech/polkadot-sdk-docs/issues/31
- https://github.com/paritytech/polkadot-sdk-docs/issues/4
- https://github.com/paritytech/polkadot-sdk-docs/issues/26 
- https://github.com/paritytech/polkadot-sdk-docs/issues/32
- https://github.com/paritytech/polkadot-sdk-docs/issues/36


### After This Pull Request

- [ ] create a redirect for
https://paritytech.github.io/polkadot-sdk/master/substrate/
- [x] analytics 
- [ ] link checker
- [ ] the matter of publishing, and how all of these relative links for
when we do, that is still an open question. There is section on this in
the landing page.
- [ ] updated https://paritytech.github.io/

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

PG Herveou authored Nov 29, 2023



see #2189

This PR does the following:
- Bring the user api functions into a new pallet-contracts-uapi (They
are currently defined in ink!
[here])(https://github.com/paritytech/ink/blob/master/crates/env/src/engine/on_chain/ext.rs)
- Add older api versions and unstable to the user api trait.
- Remove pallet-contracts-primitives and bring the types it defined in
uapi / pallet-contracts
- Add the infrastructure to build fixtures from Rust files and test it
works by replacing `dummy.wat` and `call.wat`
- Move all the doc from wasm/runtime.rs to pallet-contracts-uapi.

This will be done in a follow up:
- convert the rest of the test from .wat to rust
- bring risc-v uapi up to date with wasm
- finalize the uapi host fns, making sure everything is codegen from the
source host fns in pallet-contracts

Remove system parachains Polkadot and Kusama runtimes (#1737) · 63ac2471

Dónal Murray authored Nov 29, 2023

Since the Polkadot and Kusama runtimes are no longer in the repo, the
relevant systems parachains runtimes also need to be removed. More
context [here](https://github.com/paritytech/polkadot-sdk/issues/603)
and [here](https://github.com/paritytech/polkadot-sdk/pull/1731).

Removes the following:
- `asset-hub-kusama` and `asset-hub-polkadot`
- `bridge-hub-kusama` and `bridge-hub-polkadot`
- `collectives-polkadot`
- `glutton-kusama`

Partially solves #603 and adds to #1731.
