`chain-spec`/presets reference docs added (#4678) · 42ddb5b0


Added reference doc about:
- the pallet genesis config and genesis build, 
- runtime `genesis-builder` API,
- presets,
- interacting with the `chain-spec-builder` tool

I've added [minimal
runtime](https://github.com/paritytech/polkadot-sdk/tree/mku-chain-spec-guide/docs/sdk/src/reference_docs/chain_spec_runtime)
to demonstrate above topics.

I also sneaked in some little improvement to `chain-spec-builder` which
allows to parse output of the `list-presets` command.

Polkadot-SDK Umbrella Crate (#3935) · 1c7a1a58

Oliver Tale-Yazdi authored 10 months ago


# Umbrella Crate

The Polkadot-SDK "umbrella" is a crate that re-exports all other
published crates. This makes it
possible to have a very small `Cargo.toml` file that only has one
dependency, the umbrella
crate. This helps with selecting the right combination of crate
versions, since otherwise 3rd
party tools are needed to select a compatible set of versions.

## Features

The umbrella crate supports no-std builds and can therefore be used in
the runtime and node.
There are two main features: `runtime` and `node`. The `runtime` feature
enables all `no-std`
crates, while the `node` feature enables all `std` crates. It should be
used like any other
crate in the repo, with `default-features = false`.

For more fine-grained control, additionally, each crate can be enabled
selectively. The umbrella
exposes one feature per dependency. For example, if you only want to use
the `frame-support`
crate, you can enable the `frame-support` feature.

The umbrella exposes a few more general features:
- `tuples-96`: Needs to be enabled for runtimes that have more than 64
pallets.
- `serde`: Specifically enable `serde` en/decoding support.
- `experimental`: Experimental enable experimental features - should not
yet used in production.
- `with-tracing`: Enable tracing support.
- `try-runtime`, `runtime-benchmarks` and `std`: These follow the
standard conventions.
- `runtime`: As described above, enable all `no-std` crates.
- `node`: As described above, enable all `std` crates.
- There does *not* exist a dedicated docs feature. To generate docs,
enable the `runtime` and
`node` feature. For docs.rs the manifest contains specific configuration
to make it show up
  all re-exports.

There is a specific `zepter` check in place to ensure that the features
of the umbrella are
correctly configured. This check is run in CI and locally when running
`zepter`.

## Generation

The umbrella crate needs to be updated every time when a new crate is
added or removed from the
workspace. It is checked in CI by calling its generation script. The
generation script is
located in `./scripts/generate-umbrella.py` and needs dependency
`cargo_workspace`.

Example: `python3 scripts/generate-umbrella.py --sdk . --version 1.9.0`

## Usage

> Note: You can see a live example in the `staging-node-cli` and
`kitchensink-runtime` crates.

The umbrella crate can be added to your runtime crate like this:

`polkadot-sdk = { path = "../../../../umbrella", features = ["runtime"],
default-features =
false}`

or for a node:

`polkadot-sdk = { path = "../../../../umbrella", features = ["node"],
default-features = false
}`

In the code, it is then possible to bring all dependencies into scope
via:

`use polkadot_sdk::*;`

### Known Issues

The only known issue so far is the fact that the `use` statement brings
the dependencies only
into the outer module scope - not the global crate scope. For example,
the following code would
need to be adjusted:

```rust
use polkadot_sdk::*;

mod foo {
   // This does sadly not compile:
   frame_support::parameter_types! { }

   // Instead, we need to do this (or add an equivalent `use` statement):
   polkadot_sdk::frame_support::parameter_types! { }
}
```

Apart from this, no issues are known. There could be some bugs with how
macros locate their own
re-exports. Please compile issues that arise from using this crate.

## Dependencies

The umbrella crate re-exports all published crates, with a few
exceptions:
- Runtime crates like `rococo-runtime` etc are not exported. This
otherwise leads to very weird
  compile errors and should not be needed anyway.
- Example and fuzzing crates are not exported. This is currently
detected by checking the name
of the crate for these magic words. In the future, it will utilize
custom metadata, as it is
  done in the `rococo-runtime` crate.
- The umbrella crate itself. Should be obvious :)

## Follow Ups
- [ ] Re-writing the generator in Rust - the python script is at its
limit.
- [ ] Using custom metadata to exclude some crates instead of filtering
by names.
- [ ] Finding a way to setting the version properly. Currently its
locked in the CI script.

Refactor Nomination Pool to support multiple staking strategies (#3905) · 8949856d

Ankan authored 10 months ago

Third and final PR in the set, closes
https://github.com/paritytech/polkadot-sdk/issues/454.

Original PR: https://github.com/paritytech/polkadot-sdk/pull/2680

## Precursors:
- https://github.com/paritytech/polkadot-sdk/pull/3889.
- https://github.com/paritytech/polkadot-sdk/pull/3904.

## Follow up issues/improvements
- https://github.com/paritytech/polkadot-sdk/issues/4404

Overall changes are documented here (lot more visual 

):
https://hackmd.io/@ak0n/454-np-governance

## Summary of various roles 🤯
### Pallet Staking
**Nominator**: An account that directly stakes on `pallet-staking` and
nominates a set of validators.
**Stakers**: Common term for nominators and validators.
Virtual Stakers: Same as stakers, but they are keyless accounts and
their locks are managed by a pallet external to `pallet-staking`.

### Pallet Delegated Staking
**Agent**: An account that receives delegation from other accounts
(delegators) and stakes on their behalf. They are also Virtual Stakers
in `pallet-staking` where `pallet-delegated-staking` manages its locks.
**Delegator**: An account that delegates some funds to an agent.

### Pallet Nomination Pools
**Pool account**: Keyless account of a pool where funds are pooled.
Members pledge their funds towards the pools. These are going to become
`Agent` accounts in `pallet-delegated-staking`.
**Pool Members**: They are individual members of the pool who
contributed funds to it. They are also `Delegator` in
`pallet-delegated-staking`.

## Changes
### Multiple Stake strategies

**TransferStake**: The current nomination pool logic can be considered a
staking strategy where delegators transfer funds to pool and stake. In
this scenario, funds are locked in pool account, and users lose the
control of their funds.

**DelegateStake**: With this PR, we introduce a new staking strategy
where individual delegators delegate fund to pool. `Delegate` implies
funds are locked in delegator account itself. Important thing to note
is, pool does not have funds of its own, but it has authorization from
its members to use these funds for staking.

We extract out all the interaction of pool with staking interface into a
new trait `StakeStrategy`. This is the logic that varies between the
above two staking strategies. We use the trait `StakeStrategy` to
implement above two strategies: `TransferStake` and `DelegateStake`.

### NominationPool
Consumes an implementation of `StakeStrategy` instead of
`StakingInterface`. I have renamed it from `Staking` to `StakeAdapter`
to clarify the difference from the earlier used trait.

To enable delegation based staking in pool, Nomination pool can be
configured as:
```
type StakeAdapter = pallet_nomination_pools::adapter::DelegateStake<Self, DelegatedStaking>;
```

Note that with the following configuration, the changes in the PR are
no-op.
```
type StakeAdapter = pallet_nomination_pools::adapter::TransferStake<Self, Staking>;
```

## Deployment roadmap
Plan to enable this only in Westend. In production runtimes, we can keep
pool to use `TransferStake` which will be no functional change.

Once we have a full audit, we can enable this in Kusama followed by
Polkadot.

## TODO
- [x] Runtime level (Westend) migration for existing nomination pools.
- [x] Permissionless call/ pallet::tasks for claiming delegator funds.
- [x] Add/update benches.
- [x] Migration tests.
- [x] Storage flag to mark `DelegateStake` migration and integrity
checks to not allow `TransferStake` for migrated runtimes.

XCM Cookbook (#2633) · 289f5bbf

Francisco Aguirre authored 10 months ago


# Context

XCM docs are currently an md book hosted with github pages:
https://paritytech.github.io/xcm-docs/.
While that's fine, it's not in line with the work being done in the
polkadot-sdk docs.

# Main addition

This PR aims to fix that by bringing the docs back to this repo.
This does not have all the information currently present in the mdbook
xcm-docs but aims to be a good chunk of it and fully replace it over
time.

I also added the sections `guides` and `cookbook` which will be very
useful for users wanting to get into XCM.
For now I only added one example to the cookbook, but have ideas for
guides and more examples.
Having this docs be in rust docs is very useful for the cookbook.

# TODO

- [x] Use `FungibleAdapter`
- [x] Improve and relocate mock message queue
- [x] Fix license issue. Why does docs/sdk/ not have this problem? (Just
added the licenses)

# Next steps

- More examples in the cookbook
- End-to-end XCM guide with zombienet testing

Introduces: Delegated Staking Pallet (#3904) · 4d47b443

Ankan authored 10 months ago

This is the second PR in preparation for
https://github.com/paritytech/polkadot-sdk/issues/454.

## Also see
- **Precursor** https://github.com/paritytech/polkadot-sdk/pull/3889.
- **Follow up** https://github.com/paritytech/polkadot-sdk/pull/3905.

Overall changes are documented here (lot more visual 

):
https://hackmd.io/@ak0n/454-np-governance

## Changes
### Delegation Interface
Provides delegation primitives for staking. 

Introduces two new roles:
- Agent: These are accounts who receive delegation from other accounts
(delegators) and stakes on behalf of them. The funds are held in
delegator accounts.
- Delegator: Accounts who delegate their funds to an agent authorising
them to use it for staking.

Supports
- A way for delegators to add or withdraw delegation to an agent.
- A way for an agent to slash a delegator during a slashing event.

### Pallet Delegated Staking
- Implements `DelegationInterface`.
- Lazy slashing: Any slashes to an Agent is posted in a ledger but not
immediately slashed. The agent can call
`DelegationInterface::delegator_slash` to slash the member and clear the
corresponding slash from its ledger.
- Consumes `StakingInterface` to provide `CoreStaking` features. In
reality, this will be `pallet-staking`.
- Ensures bookkeeping for agent and delegator are correct but leaves the
management of reward and slash logic upto the consumer of this pallet.
- While it does not expose any calls yet, it is written with the intent
of exposing these primitives via extrinsics.

## TODO
- [x] Improve unit tests in the pallet.
- [x] Separate slash reward perbill for rewarding the slash reporters?
- [x] Review if we should add more events.

Integrate litep2p into Polkadot SDK (#2944) · 80616f6d

Aaro Altonen authored 11 months ago

[litep2p](https://github.com/altonen/litep2p) is a libp2p-compatible P2P
networking library. It supports all of the features of `rust-libp2p`
that are currently being utilized by Polkadot SDK.

Compared to `rust-libp2p`, `litep2p` has a quite different architecture
which is why the new `litep2p` network backend is only able to use a
little of the existing code in `sc-network`. The design has been mainly
influenced by how we'd wish to structure our networking-related code in
Polkadot SDK: independent higher-levels protocols directly communicating
with the network over links that support bidirectional backpressure. A
good example would be `NotificationHandle`/`RequestResponseHandle`
abstractions which allow, e.g., `SyncingEngine` to directly communicate
with peers to announce/request blocks.

I've tried running `polkadot --network-backend litep2p` with a few
different peer configurations and there is a noticeable reduction in
networking CPU usage. For high load (`...

[FRAME] Runtime Omni Bencher (#3512) · 9543d314

Oliver Tale-Yazdi authored 11 months ago

This MR contains two major changes and some maintenance cleanup.  

## 1. Free Standing Pallet Benchmark Runner

Closes https://github.com/paritytech/polkadot-sdk/issues/3045, depends
on your runtime exposing the `GenesisBuilderApi` (like
https://github.com/paritytech/polkadot-sdk/pull/1492).

Introduces a new binary crate: `frame-omni-bencher`.  
It allows to directly benchmark a WASM blob - without needing a node or
chain spec.

This makes it much easier to generate pallet weights and should allow us
to remove bloaty code from the node.
It should work for all FRAME runtimes that dont use 3rd party host calls
or non `BlakeTwo256` block hashing (basically all polkadot parachains
should work).

It is 100% backwards compatible with the old CLI args, when the `v1`
compatibility command is used. This is done to allow for forwards
compatible addition of new commands.

### Example (full example in the Rust docs)

Installing the CLI:
```sh

XCM Fee Payment Runtime API (#3607) · 3c972fc1

Pavel Orlov authored 1 year ago

The PR provides API for obtaining:
- the weight required to execute an XCM message,
- a list of acceptable `AssetId`s for message execution payment,
- the cost of the weight in the specified acceptable `AssetId`.

It is meant to address an issue where one has to guess how much fee to
pay for execution. Also, at the moment, a client has to guess which
assets are acceptable for fee execution payment.
See the related issue
https://github.com/paritytech/polkadot-sdk/issues/690.
With this API, a client is supposed to query the list of the supported
asset IDs (in the XCM version format the client understands), weigh the
XCM program the client wants to execute and convert the weight into one
of the acceptable assets. Note that the client is supposed to know what
program will be executed on what chains. However, having a small
companion JS library for the pallet-xcm and xtokens should be enough to
determine what XCM programs will be executed and where (since these

Add a PolkaVM-based executor (#3458) · b0f34e4b

Koute authored 1 year ago

This PR adds a new PolkaVM-based executor to Substrate.

- The executor can now be used to actually run a PolkaVM-based runtime,
and successfully produces blocks.
- The executor is always compiled-in, but is disabled by default.
- The `SUBSTRATE_ENABLE_POLKAVM` environment variable must be set to `1`
to enable the executor, in which case the node will accept both WASM and
PolkaVM program blobs (otherwise it'll default to WASM-only). This is
deliberately undocumented and not explicitly exposed anywhere (e.g. in
the command line arguments, or in the API) to disincentivize anyone from
enabling it in production. If/when we'll move this into production usage
I'll remove the environment variable and do it "properly".
- I did not use our legacy runtime allocator for the PolkaVM executor,
so currently every allocation inside of the runtime will leak guest
memory until that particular instance is destroyed. The idea here is
that I will work on the https://github.com/polkadot-fellows/RFCs/pull/4
which will remove the need for the legacy allocator under WASM, and that
will also allow us to use a proper non-leaking allocator under PolkaVM.
- I also did some minor cleanups of the WASM executor and deleted some
dead code.

No prdocs included since this is not intended to be an end-user feature,
but an unofficial experiment, and shouldn't affect any current
production user. Once this is production-ready a full Polkadot
Fellowship RFC will be necessary anyway.

Multi-Block-Migrations, `poll` hook and new System callbacks (#1781) · eefd5fe4

Oliver Tale-Yazdi authored 1 year ago


This MR is the merge of
https://github.com/paritytech/substrate/pull/14414 and
https://github.com/paritytech/substrate/pull/14275. It implements
[RFC#13](https://github.com/polkadot-fellows/RFCs/pull/13), closes
https://github.com/paritytech/polkadot-sdk/issues/198.

----- 

This Merge request introduces three major topicals:

1. Multi-Block-Migrations
1. New pallet `poll` hook for periodic service work
1. Replacement hooks for `on_initialize` and `on_finalize` in cases
where `poll` cannot be used

and some more general changes to FRAME.  
The changes for each topical span over multiple crates. They are listed
in topical order below.

# 1.) Multi-Block-Migrations

Multi-Block-Migrations are facilitated by creating `pallet_migrations`
and configuring `System::Config::MultiBlockMigrator` to point to it.
Executive picks this up and triggers one step of the migrations pallet
per block.
The chain is in lockdown mode for as long as an MBM is ongoing.
Executive does this by polling `MultiBlockMigrator::ongoing` and not
allowing any transaction in a block, if true.

A MBM is defined through trait `SteppedMigration`. A condensed version
looks like this:
```rust
/// A migration that can proceed in multiple steps.
pub trait SteppedMigration {
	type Cursor: FullCodec + MaxEncodedLen;
	type Identifier: FullCodec + MaxEncodedLen;

	fn id() -> Self::Identifier;

	fn max_steps() -> Option<u32>;

	fn step(
		cursor: Option<Self::Cursor>,
		meter: &mut WeightMeter,
	) -> Result<Option<Self::Cursor>, SteppedMigrationError>;
}
```

`pallet_migrations` can be configured with an aggregated tuple of these
migrations. It then starts to migrate them one-by-one on the next
runtime upgrade.
Two things are important here:
- 1. Doing another runtime upgrade while MBMs are ongoing is not a good
idea and can lead to messed up state.
- 2. **Pallet Migrations MUST BE CONFIGURED IN `System::Config`,
otherwise it is not used.**

The pallet supports an `UpgradeStatusHandler` that can be used to notify
external logic of upgrade start/finish (for example to pause XCM
dispatch).

Error recovery is very limited in the case that a migration errors or
times out (exceeds its `max_steps`). Currently the runtime dev can
decide in `FailedMigrationHandler::failed` how to handle this. One
follow-up would be to pair this with the `SafeMode` pallet and enact
safe mode when an upgrade fails, to allow governance to rescue the
chain. This is currently not possible, since governance is not
`Mandatory`.

## Runtime API

- `Core`: `initialize_block` now returns `ExtrinsicInclusionMode` to
inform the Block Author whether they can push transactions.

### Integration

Add it to your runtime implementation of `Core` and `BlockBuilder`:
```patch
diff --git a/runtime/src/lib.rs b/runtime/src/lib.rs
@@ impl_runtime_apis! {
	impl sp_block_builder::Core<Block> for Runtime {
-		fn initialize_block(header: &<Block as BlockT>::Header) {
+		fn initialize_block(header: &<Block as BlockT>::Header) -> RuntimeExecutiveMode {
			Executive::initialize_block(header)
		}

		...
	}
```

# 2.) `poll` hook

A new pallet hook is introduced: `poll`. `Poll` is intended to replace
mostly all usage of `on_initialize`.
The reason for this is that any code that can be called from
`on_initialize` cannot be migrated through an MBM. Currently there is no
way to statically check this; the implication is to use `on_initialize`
as rarely as possible.
Failing to do so can result in broken storage invariants.

The implementation of the poll hook depends on the `Runtime API` changes
that are explained above.

# 3.) Hard-Deadline callbacks

Three new callbacks are introduced and configured on `System::Config`:
`PreInherents`, `PostInherents` and `PostTransactions`.
These hooks are meant as replacement for `on_initialize` and
`on_finalize` in cases where the code that runs cannot be moved to
`poll`.
The reason for this is to make the usage of HD-code (hard deadline) more
explicit - again to prevent broken invariants by MBMs.

# 4.) FRAME (general changes)

## `frame_system` pallet

A new memorize storage item `InherentsApplied` is added. It is used by
executive to track whether inherents have already been applied.
Executive and can then execute the MBMs directly between inherents and
transactions.

The `Config` gets five new items:
- `SingleBlockMigrations` this is the new way of configuring migrations
that run in a single block. Previously they were defined as last generic
argument of `Executive`. This shift is brings all central configuration
about migrations closer into view of the developer (migrations that are
configured in `Executive` will still work for now but is deprecated).
- `MultiBlockMigrator` this can be configured to an engine that drives
MBMs. One example would be the `pallet_migrations`. Note that this is
only the engine; the exact MBMs are injected into the engine.
- `PreInherents` a callback that executes after `on_initialize` but
before inherents.
- `PostInherents` a callback that executes after all inherents ran
(including MBMs and `poll`).
- `PostTransactions` in symmetry to `PreInherents`, this one is called
before `on_finalize` but after all transactions.

A sane default is to set all of these to `()`. Example diff suitable for
any chain:
```patch
@@ impl frame_system::Config for Test {
 	type MaxConsumers = ConstU32<16>;
+	type SingleBlockMigrations = ();
+	type MultiBlockMigrator = ();
+	type PreInherents = ();
+	type PostInherents = ();
+	type PostTransactions = ();
 }
```

An overview of how the block execution now looks like is here. The same
graph is also in the rust doc.

Runtime Upgrade ref docs and Single Block Migration example pallet (#1554) · 12ce4f7d

Liam Aharon authored 1 year ago

Closes https://github.com/paritytech/polkadot-sdk-docs/issues/55

- Changes 'current storage version' terminology to less ambiguous
'in-code storage version' (suggestion by @ggwpez

)
- Adds a new example pallet `pallet-example-single-block-migrations`
- Adds a new reference doc to replace
https://docs.substrate.io/maintain/runtime-upgrades/ (temporarily living
in the pallet while we wait for developer hub PR to merge)
- Adds documentation for the `storage_alias` macro
- Improves `trait Hooks` docs 
- Improves `trait GetStorageVersion` docs
- Update the suggested patterns for using `VersionedMigration`, so that
version unchecked migrations are never exported
- Prevents accidental usage of version unchecked migrations in runtimes

https://github.com/paritytech/substrate/pull/14421#discussion_r1255467895
- Unversioned migration code is kept inside `mod version_unchecked`,
versioned code is kept in `pub mod versioned`
- It is necessary to use modules to limit visibility because the inner
migration must be `pub`. See
https://github.com/rust-lang/rust/issues/30905 and

https://internals.rust-lang.org/t/lang-team-minutes-private-in-public-rules/4504/40

PoV Reclaim Runtime Side (#3002) · 3386377b

Sebastian Kunert authored 1 year ago


# Runtime side for PoV Reclaim

## Implementation Overview
- Hostfunction to fetch the storage proof size has been added to the
PVF. It uses the size tracking recorder that was introduced in my
previous PR.
- Mechanisms to use the reclaim HostFunction have been introduced.
- 1. A SignedExtension that checks the node-reported proof size before
and after application of an extrinsic. Then it reclaims the difference.
- 2. A manual helper to make reclaiming easier when manual interaction
is required, for example in `on_idle` or other hooks.
- In order to utilize the manual reclaiming, I modified `WeightMeter` to
support the reduction of consumed weight, at least for storage proof
size.

## How to use
To enable the general functionality for a parachain:
1. Add the SignedExtension to your parachain runtime. 
2. Provide the HostFunction to the node
3. Enable proof recording during block import

Lift dependencies to the workspace (Part 2/x) (#3366) · e89d0fca

Oliver Tale-Yazdi authored 1 year ago


Lifting some more dependencies to the workspace. Just using the
most-often updated ones for now.
It can be reproduced locally.

```sh
# First you can check if there would be semver incompatible bumps (looks good in this case):
$ zepter transpose dependency lift-to-workspace --ignore-errors syn quote thiserror "regex:^serde.*"

# Then apply the changes:
$ zepter transpose dependency lift-to-workspace --version-resolver=highest syn quote thiserror "regex:^serde.*" --fix

# And format the changes:
$ taplo format --config .config/taplo.toml
```

Lift dependencies to the workspace (Part 1) (#2070) · e80c2473

Oliver Tale-Yazdi authored 1 year ago

Changes (partial https://github.com/paritytech/polkadot-sdk/issues/994):
- Set log to `0.4.20` everywhere
- Lift `log` to the workspace

Starting with a simpler one after seeing
https://github.com/paritytech/polkadot-sdk/pull/2065 from @jsdw

.
This sets the `default-features` to `false` in the root and then
overwrites that in each create to its original value. This is necessary
since otherwise the `default` features are additive and its impossible
to disable them in the crate again once they are enabled in the
workspace.

I am using a tool to do this, so its mostly a test to see that it works
as expected.

[FRAME] Parameters pallet (#2061) · e53ebd8c

Oliver Tale-Yazdi authored 1 year ago


Closes #169  

Fork of the `orml-parameters-pallet` as introduced by
https://github.com/open-web3-stack/open-runtime-module-library/pull/927
(cc @xlc)
It greatly changes how the macros work, but keeps the pallet the same.
The downside of my code is now that it does only support constant keys
in the form of types, not value-bearing keys.
I think this is an acceptable trade off, give that it can be used by
*any* pallet without any changes.

The pallet allows to dynamically set parameters that can be used in
pallet configs while also restricting the updating on a per-key basis.
The rust-docs contains a complete example.

Changes:
- Add `parameters-pallet`
- Use in the kitchensink as demonstration
- Add experimental attribute to define dynamic params in the runtime.
- Adding a bunch of traits to `frame_support::traits::dynamic_params`
that can be re-used by the ORML macros

## Example

First to define the parameters in the runtime file. The syntax is very
explicit about the codec index and errors if there is no.
```rust
#[dynamic_params(RuntimeParameters, pallet_parameters::Parameters::<Runtime>))]
pub mod dynamic_params {
	use super::*;

	#[dynamic_pallet_params]
	#[codec(index = 0)]
	pub mod storage {
		/// Configures the base deposit of storing some data.
		#[codec(index = 0)]
		pub static BaseDeposit: Balance = 1 * DOLLARS;

		/// Configures the per-byte deposit of storing some data.
		#[codec(index = 1)]
		pub static ByteDeposit: Balance = 1 * CENTS;
	}

	#[dynamic_pallet_params]
	#[codec(index = 1)]
	pub mod contracts {
		#[codec(index = 0)]
		pub static DepositPerItem: Balance = deposit(1, 0);

		#[codec(index = 1)]
		pub static DepositPerByte: Balance = deposit(0, 1);
	}
}
```

Then the pallet is configured with the aggregate:  
```rust
impl pallet_parameters::Config for Runtime {
	type AggregratedKeyValue = RuntimeParameters;
	type AdminOrigin = EnsureRootWithSuccess<AccountId, ConstBool<true>>;
	...
}
```

And then the parameters can be used in a pallet config:
```rust
impl pallet_preimage::Config for Runtime {
	type DepositBase = dynamic_params::storage::DepositBase;
}
```

A custom origin an be defined like this:  
```rust
pub struct DynamicParametersManagerOrigin;

impl EnsureOriginWithArg<RuntimeOrigin, RuntimeParametersKey> for DynamicParametersManagerOrigin {
	type Success = ();

	fn try_origin(
		origin: RuntimeOrigin,
		key: &RuntimeParametersKey,
	) -> Result<Self::Success, RuntimeOrigin> {
		match key {
			RuntimeParametersKey::Storage(_) => {
				frame_system::ensure_root(origin.clone()).map_err(|_| origin)?;
				return Ok(())
			},
			RuntimeParametersKey::Contract(_) => {
				frame_system::ensure_root(origin.clone()).map_err(|_| origin)?;
				return Ok(())
			},
		}
	}

	#[cfg(feature = "runtime-benchmarks")]
	fn try_successful_origin(_key: &RuntimeParametersKey) -> Result<RuntimeOrigin, ()> {
		Ok(RuntimeOrigin::Root)
	}
}
```

Build more runtimes targeting PolkaVM (#3209) · 402b64ca

Koute authored 1 year ago

This PR improves compatibility with RISC-V and PolkaVM, allowing more
runtimes to successfully compile.

In particular, it makes the following changes:

- The `sp-mmr-primitives` and `sp-consensus-beefy` crates
unconditionally required an `std`-only dependency; now they only require
those dependencies when the `std` feature is actually enabled. (Our
RISC-V target is, unlike WASM, a true `no_std` target where you can't
accidentally use stuff from `std` anymore.)
- One of our dependencies (the `bitvec` trace) uses a crate called
`radium` which doesn't compile under RISC-V due to incomplete
autodetection logic in their `build.rs` file. The good news is that this
is already fixed in the newest upstream version of `radium`, and the
newest version of `bitvec` uses it. The bad news is that the newest
version of `bitvec` is not currently released on crates.io, so we can't
use it. I've [created an
issue](https://github.com/ferrilab/ferrilab/issues/5) asking for a new
release, but in the meantime I forked the currently used `radium` 0.7,
[fixed the faulty
logic](https://github.com/paritytech/radium-0.7-fork/commit/ed66c8a294b138c67f93499644051d97d4c7fbda)
and used cargo's patching capabilities to use it for the RISC-V runtime
builds. This might be a little hacky, but it is the least intrusive way
to fix the problem, doesn't affect WASM builds at all, and we can
trivially remove it once a new `bitvec` is released.
- The new runtimes are added to the CI to make sure their compilation
doesn't break.

Initial support for building RISC-V runtimes targeting PolkaVM (#3179) · e349fc9e

Koute authored 1 year ago

This PR adds initial support for building RISC-V runtimes targeting
PolkaVM.

- Setting the `SUBSTRATE_RUNTIME_TARGET=riscv` environment variable will
now build a RISC-V runtime instead of a WASM runtime.
- This only adds support for *building* runtimes; running them will need
a PolkaVM-based executor, which I will add in a future PR.
- Only building the minimal runtime is supported (building the Polkadot
runtime doesn't work *yet* due to one of the dependencies).
- The builder now sets a `substrate_runtime` cfg flag when building the
runtimes, with the idea being that instead of doing `#[cfg(not(feature =
"std"))]` or `#[cfg(target_arch = "wasm32")]` to detect that we're
building a runtime you'll do `#[cfg(substrate_runtime)]`. (Switching the
whole codebase to use this will be done in a future PR; I deliberately
didn't do this here to keep this PR minimal and reviewable.)
- Further renaming of things (e.g. types, environment variables and proc
macro attributes having "wasm" in their name) to be target-agnostic will
also be done in a future refactoring PR (while keeping backwards
compatibility where it makes sense; I don't intend to break anyone's
workflow or create unnecessary churn).
- This PR also fixes two bugs in the `wasm-builder` crate:
* The `RUSTC` environment variable is now removed when invoking the
compiler. This prevents the toolchain version from being overridden when
called from a `build.rs` script.
* When parsing the `rustup toolchain list` output the `(default)` is now
properly stripped and not treated as part of the version.
- I've also added a minimal CI job that makes sure this doesn't break in
the future. (cc @paritytech/ci)

cc @athei



------

Also, just a fun little tidbit: quickly comparing the size of the built
runtimes it seems that the PolkaVM runtime is slightly smaller than the
WASM one. (`production` build, with the `names` section substracted from
the WASM's size to keep things fair, since for the PolkaVM runtime we're
currently stripping out everything)

- `.wasm`: 625505 bytes
- `.wasm` (after wasm-opt -O3): 563205 bytes
- `.wasm` (after wasm-opt -Os): 562987 bytes
- `.wasm` (after wasm-opt -Oz): 536852 bytes
- `.polkavm`: ~~580338 bytes~~ 550476 bytes (after enabling extra target
features; I'll add those in another PR once we have an executor working)

Add subsystem benchmarks for `availability-distribution` and... · 47e46d17

Andrei Sandu authored 1 year ago

Add subsystem benchmarks for `availability-distribution` and `biftield-distribution` (availability write) (#2970)

Introduce a new test objective : `DataAvailabilityWrite`.

The new benchmark measures the network and cpu usage of
`availability-distribution`, `biftield-distribution` and
`availability-store` subsystems from the perspective of a validator node
during the process when candidates are made available.

Additionally I refactored the networking emulation to support bandwidth
acounting and limits of incoming and outgoing requests.

Move cryptographic hashing procedures to crypto folder. (#2306) · 4c10fd2a

Davide Galassi authored 1 year ago


Step towards https://github.com/paritytech/polkadot-sdk/issues/1975

As reported
https://github.com/paritytech/polkadot-sdk/issues/1975#issuecomment-1774534225
I'd like to encapsulate crypto related stuff in a dedicated folder.

Currently all cryptographic primitive wrappers are all sparsed in
`substrate/core` which contains "misc core" stuff.

To simplify the process, as the first step with this PR I propose to
move the cryptographic hashing there.

The `substrate/crypto` folder was already created to contains `ec-utils`
crate.

Notes:
- rename `sp-core-hashing` to `sp-crypto-hashing`
- rename `sp-core-hashing-proc-macro` to `sp-crypto-hashing-proc-macro`
- As the crates name is changed I took the freedom to restart fresh from
version 0.1.0 for both crates
