rpc server: add prometheus label `is_rate_limited` (#3504) · efcea0ed

Niklas Adolfsson authored Mar 05, 2024

After some discussion with @kogeler

 after the we added the rate-limit
middleware it may slow down
the rpc call timings metrics significantly because it works as follows:

1. The rate limit guard is checked when the call comes and if a slot is
available -> process the call
2. If no free spot is available then the call will be sleeping
`jitter_delay + min_time_rate_guard` then woken up and checked at most
ten times
3. If no spot is available after 10 iterations -> the call is rejected
(this may take tens of seconds)

Thus, this PR adds a label "is_rate_limited" to filter those out on the
metrics "substrate_rpc_calls_time" and "substrate_rpc_calls_finished".

I had to merge two middleware layers Metrics and RateLimit to avoid
shared state in a hacky way.

FRAME: Create `TransactionExtension` as a replacement for `SignedExtension` (#2280) · fd5f9292

Gavin Wood authored Mar 04, 2024



Closes #2160

First part of [Extrinsic
Horizon](https://github.com/paritytech/polkadot-sdk/issues/2415)

Introduces a new trait `TransactionExtension` to replace
`SignedExtension`. Introduce the idea of transactions which obey the
runtime's extensions and have according Extension data (né Extra data)
yet do not have hard-coded signatures.

Deprecate the terminology of "Unsigned" when used for
transactions/extrinsics owing to there now being "proper" unsigned
transactions which obey the extension framework and "old-style" unsigned
which do not. Instead we have __*General*__ for the former and
__*Bare*__ for the latter. (Ultimately, the latter will be phased out as
a type of transaction, and Bare will only be used for Inherents.)

Types of extrinsic are now therefore:
- Bare (no hardcoded signature, no Extra data; used to be known as
"Unsigned")
- Bare transactions (deprecated): Gossiped, validated with
`ValidateUnsigned` (deprecated) and the `_bare_compat` bits of
`TransactionExtension` (deprecated).
  - Inherents: Not gossiped, validated with `ProvideInherent`.
- Extended (Extra data): Gossiped, validated via `TransactionExtension`.
  - Signed transactions (with a hardcoded signature).
  - General transactions (without a hardcoded signature).

`TransactionExtension` differs from `SignedExtension` because:
- A signature on the underlying transaction may validly not be present.
- It may alter the origin during validation.
- `pre_dispatch` is renamed to `prepare` and need not contain the checks
present in `validate`.
- `validate` and `prepare` is passed an `Origin` rather than a
`AccountId`.
- `validate` may pass arbitrary information into `prepare` via a new
user-specifiable type `Val`.
- `AdditionalSigned`/`additional_signed` is renamed to
`Implicit`/`implicit`. It is encoded *for the entire transaction* and
passed in to each extension as a new argument to `validate`. This
facilitates the ability of extensions to acts as underlying crypto.

There is a new `DispatchTransaction` trait which contains only default
function impls and is impl'ed for any `TransactionExtension` impler. It
provides several utility functions which reduce some of the tedium from
using `TransactionExtension` (indeed, none of its regular functions
should now need to be called directly).

Three transaction version discriminator ("versions") are now
permissible:
- 0b000000100: Bare (used to be called "Unsigned"): contains Signature
or Extra (extension data). After bare transactions are no longer
supported, this will strictly identify an Inherents only.
- 0b100000100: Old-school "Signed" Transaction: contains Signature and
Extra (extension data).
- 0b010000100: New-school "General" Transaction: contains Extra
(extension data), but no Signature.

For the New-school General Transaction, it becomes trivial for authors
to publish extensions to the mechanism for authorizing an Origin, e.g.
through new kinds of key-signing schemes, ZK proofs, pallet state,
mutations over pre-authenticated origins or any combination of the
above.

## Code Migration

### NOW: Getting it to build

Wrap your `SignedExtension`s in `AsTransactionExtension`. This should be
accompanied by renaming your aggregate type in line with the new
terminology. E.g. Before:

```rust
/// The SignedExtension to the basic transaction logic.
pub type SignedExtra = (
	/* snip */
	MySpecialSignedExtension,
);
/// Unchecked extrinsic type as expected by this runtime.
pub type UncheckedExtrinsic =
	generic::UncheckedExtrinsic<Address, RuntimeCall, Signature, SignedExtra>;
```

After:

```rust
/// The extension to the basic transaction logic.
pub type TxExtension = (
	/* snip */
	AsTransactionExtension<MySpecialSignedExtension>,
);
/// Unchecked extrinsic type as expected by this runtime.
pub type UncheckedExtrinsic =
	generic::UncheckedExtrinsic<Address, RuntimeCall, Signature, TxExtension>;
```

You'll also need to alter any transaction building logic to add a
`.into()` to make the conversion happen. E.g. Before:

```rust
fn construct_extrinsic(
		/* snip */
) -> UncheckedExtrinsic {
	let extra: SignedExtra = (
		/* snip */
		MySpecialSignedExtension::new(/* snip */),
	);
	let payload = SignedPayload::new(call.clone(), extra.clone()).unwrap();
	let signature = payload.using_encoded(|e| sender.sign(e));
	UncheckedExtrinsic::new_signed(
		/* snip */
		Signature::Sr25519(signature),
		extra,
	)
}
```

After:

```rust
fn construct_extrinsic(
		/* snip */
) -> UncheckedExtrinsic {
	let tx_ext: TxExtension = (
		/* snip */
		MySpecialSignedExtension::new(/* snip */).into(),
	);
	let payload = SignedPayload::new(call.clone(), tx_ext.clone()).unwrap();
	let signature = payload.using_encoded(|e| sender.sign(e));
	UncheckedExtrinsic::new_signed(
		/* snip */
		Signature::Sr25519(signature),
		tx_ext,
	)
}
```

### SOON: Migrating to `TransactionExtension`

Most `SignedExtension`s can be trivially converted to become a
`TransactionExtension`. There are a few things to know.

- Instead of a single trait like `SignedExtension`, you should now
implement two traits individually: `TransactionExtensionBase` and
`TransactionExtension`.
- Weights are now a thing and must be provided via the new function `fn
weight`.

#### `TransactionExtensionBase`

This trait takes care of anything which is not dependent on types
specific to your runtime, most notably `Call`.

- `AdditionalSigned`/`additional_signed` is renamed to
`Implicit`/`implicit`.
- Weight must be returned by implementing the `weight` function. If your
extension is associated with a pallet, you'll probably want to do this
via the pallet's existing benchmarking infrastructure.

#### `TransactionExtension`

Generally:
- `pre_dispatch` is now `prepare` and you *should not reexecute the
`validate` functionality in there*!
- You don't get an account ID any more; you get an origin instead. If
you need to presume an account ID, then you can use the trait function
`AsSystemOriginSigner::as_system_origin_signer`.
- You get an additional ticket, similar to `Pre`, called `Val`. This
defines data which is passed from `validate` into `prepare`. This is
important since you should not be duplicating logic from `validate` to
`prepare`, you need a way of passing your working from the former into
the latter. This is it.
- This trait takes two type parameters: `Call` and `Context`. `Call` is
the runtime call type which used to be an associated type; you can just
move it to become a type parameter for your trait impl. `Context` is not
currently used and you can safely implement over it as an unbounded
type.
- There's no `AccountId` associated type any more. Just remove it.

Regarding `validate`:
- You get three new parameters in `validate`; all can be ignored when
migrating from `SignedExtension`.
- `validate` returns a tuple on success; the second item in the tuple is
the new ticket type `Self::Val` which gets passed in to `prepare`. If
you use any information extracted during `validate` (off-chain and
on-chain, non-mutating) in `prepare` (on-chain, mutating) then you can
pass it through with this. For the tuple's last item, just return the
`origin` argument.

Regarding `prepare`:
- This is renamed from `pre_dispatch`, but there is one change:
- FUNCTIONALITY TO VALIDATE THE TRANSACTION NEED NOT BE DUPLICATED FROM
`validate`!!
- (This is different to `SignedExtension` which was required to run the
same checks in `pre_dispatch` as in `validate`.)

Regarding `post_dispatch`:
- Since there are no unsigned transactions handled by
`TransactionExtension`, `Pre` is always defined, so the first parameter
is `Self::Pre` rather than `Option<Self::Pre>`.

If you make use of `SignedExtension::validate_unsigned` or
`SignedExtension::pre_dispatch_unsigned`, then:
- Just use the regular versions of these functions instead.
- Have your logic execute in the case that the `origin` is `None`.
- Ensure your transaction creation logic creates a General Transaction
rather than a Bare Transaction; this means having to include all
`TransactionExtension`s' data.
- `ValidateUnsigned` can still be used (for now) if you need to be able
to construct transactions which contain none of the extension data,
however these will be phased out in stage 2 of the Transactions Horizon,
so you should consider moving to an extension-centric design.

## TODO

- [x] Introduce `CheckSignature` impl of `TransactionExtension` to
ensure it's possible to have crypto be done wholly in a
`TransactionExtension`.
- [x] Deprecate `SignedExtension` and move all uses in codebase to
`TransactionExtension`.
  - [x] `ChargeTransactionPayment`
  - [x] `DummyExtension`
  - [x] `ChargeAssetTxPayment` (asset-tx-payment)
  - [x] `ChargeAssetTxPayment` (asset-conversion-tx-payment)
  - [x] `CheckWeight`
  - [x] `CheckTxVersion`
  - [x] `CheckSpecVersion`
  - [x] `CheckNonce`
  - [x] `CheckNonZeroSender`
  - [x] `CheckMortality`
  - [x] `CheckGenesis`
  - [x] `CheckOnlySudoAccount`
  - [x] `WatchDummy`
  - [x] `PrevalidateAttests`
  - [x] `GenericSignedExtension`
  - [x] `SignedExtension` (chain-polkadot-bulletin)
  - [x] `RefundSignedExtensionAdapter`
- [x] Implement `fn weight` across the board.
- [ ] Go through all pre-existing extensions which assume an account
signer and explicitly handle the possibility of another kind of origin.
- [x] `CheckNonce` should probably succeed in the case of a non-account
origin.
- [x] `CheckNonZeroSender` should succeed in the case of a non-account
origin.
- [x] `ChargeTransactionPayment` and family should fail in the case of a
non-account origin.
  - [ ] 
- [x] Fix any broken tests.

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

Oliver Tale-Yazdi authored Feb 28, 2024



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.

rpc-v2/tx/tests: Add transaction broadcast tests and check propagated tx status (#3193) · f1b2189e

Alexandru Vasile authored Feb 28, 2024



This PR adds tests for the `transaction_broadcast` method.


The testing needs to coordinate the following components:
- The `TestApi` marks transactions as invalid and implements
`ChainApi::validate_transaction`
- this is what dictates if a transaction is valid or not and is called
from within the `BasicPool`
- The `BasicPool` which maintains the transactions and implements
`submit_and_watch` needed by the tx broadcast to submit the transaction
- The status of the transaction pool is exposed by mocking the BasicPool
- The `ChainHeadMockClient` which mocks the
`BlockchainEvents::import_notification_stream` needed by the tx
broadcast to know to which blocks the transaction is submitted

The following changes have been added to the substrate testing to
accommodate this:
- `TestApi` gets ` remove_invalid`, counterpart to `add_invalid` to
ensure an invalid transaction can become valid again; as well as a
priority setter for extrinsics
- `BasicPool` test constructor is extended with options for the
`PoolRotator`
- this mechanism is needed because transactions are banned for 30mins
(default) after they are declared invalid
  - testing bypasses this by providing a `Duration::ZERO`

### Testing Scenarios

- Capture the status of the transaction as it is normally broadcasted
- `transaction_stop` is valid while the transaction is in progress
- A future transaction is handled when the dependencies are completed
- Try to resubmit the transaction at a later block (currently invalid)
- An invalid transaction status is propagated; the transaction is marked
as temporarily banned; then the ban expires and transaction is
resubmitted

- 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

Introduce Notification block pinning limit (#2935) · 6c5a42a6

Sebastian Kunert authored Feb 26, 2024



While investigating some pruning issues I found some room for
improvement in the notification pin handling.

**Problem:** It was not possible to define an upper limit on
notification pins. The block pinning cache has a limit, but only handles
bodies and justifications.

After this PR, bookkeeping for notifications is managed in the pinning
worker. A limit can be defined in the worker. If that limit is crossed,
blocks that were pinned for that notification are unpinned, which now
affects the state as well as bodies and justifications. The pinned
blocks cache still has a limit, but should never be hit.

Use generic hash for runtime wasm in resolve_state_version_from_wasm (#3447) · de6d0259

tmpolaczyk authored Feb 24, 2024



Changes the runtime hash algorithm used in
`resolve_state_version_from_wasm` from `DefaultHasher` to a
caller-provided one (usually `HashingFor<Block>`), to match the one used
elsewhere.

This fixes an issue where the runtime wasm is compiled 3 times when
starting the `tanssi-node` with `--dev`. With this fix, the runtime wasm
is only compiled 2 times. The other redundant compilation is caused by
the `GenesisConfigBuilderRuntimeCaller` struct, which ignores the
runtime cache.

sc-consensus-beefy: pump gossip engine while waiting for initialization conditions (#3435) · 31546c8d

Adrian Catangiu authored Feb 22, 2024



As part of BEEFY worker/voter initialization the task waits for certain
chain and backend conditions to be fulfilled:
- BEEFY consensus enabled on-chain & GRANDPA best finalized higher than
on-chain BEEFY genesis block,
- backend has synced headers for BEEFY mandatory blocks between best
BEEFY and best GRANDPA.

During this waiting time, any messages gossiped on the BEEFY topic for
current chain get enqueued in the gossip engine, leading to RAM bloating
and output warning/error messages when the wait time is non-negligible
(like during a clean sync).

This PR adds logic to pump the gossip engine while waiting for other
things to make sure gossiped messages get consumed (practically
discarded until worker is fully initialized).

Also raises the warning threshold for enqueued messages from 10k to
100k. This is in line with the other gossip protocols on the node.

Fixes https://github.com/paritytech/polkadot-sdk/issues/3390

ProposerFactory impl Clone (#3389) · 318fed32

tmpolaczyk authored Feb 21, 2024

In Tanssi, we need a way to stop the collator code and then start it
again. This is to support rotating the same collator between different
runtimes. Currently, this works very well, except for the proposer
metrics, because they only get registered the first time they are
started. Afterwards, we see this warning log:

> Failed to register proposer prometheus metrics: Duplicate metrics
collector registration attempted


~~So this PR adds a method to set metrics, to allow us to register
metrics manually before creating the `ProposerFactory`, and then clone
the same metrics every time we need to start the collator.~~ Implemented
Clone instead

rpc-v2/tx: Remove the broadcast event from `transaction_submitAndWatch` (#3321) · 1b624c50

Alexandru Vasile authored Feb 21, 2024



This PR backports the changes from the rpc-v2 spec:
https://github.com/paritytech/json-rpc-interface-spec/pull/134

The `Broadcasted` event has been removed:
- it is hard to enforce a `Dropped { broadcasted: bool }` event in cases
of a load-balancer being placed in front of an RPC server
- when the server exists, it is impossible to guarantee this field if
the server did not previously send a `Broadcasted` event
- the number of peers reported by this event does not guarantee that
peers are unique
- the same peer can disconnect and reconnect, increasing this metric
number
- the number of peers that receive this transaction offers no guarantee
about the transaction being included in the chain at a later time

rpc server: make possible to disable/enable batch requests (#3364) · fee810a5

Niklas Adolfsson authored Feb 20, 2024

The rationale behind this, is that it may be useful for some users
actually disable RPC batch requests or limit them by length instead of
the total size bytes of the batch.

This PR adds two new CLI options:

```
--rpc-disable-batch-requests - disable batch requests on the server
--rpc-max-batch-request-len <LEN> - limit batches to LEN on the server.
```

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

Oliver Tale-Yazdi authored Feb 20, 2024



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
```

chainHead: Error on duplicate unpin hashes (#3313) · 7ec692d1

Alexandru Vasile authored Feb 14, 2024



This PR addresses an issue where calling chainHead_unpin with duplicate
hashes could lead to unintended side effects.

This backports:
https://github.com/paritytech/json-rpc-interface-spec/pull/135

While at it, have added a test to check that the global reference count
is decremented only once on unpin.

Prepare syncing for parallel sync strategies (#3224) · 96ebb305

Dmitry Markin authored Feb 13, 2024

This PR should supersede
https://github.com/paritytech/polkadot-sdk/pull/2814 and accomplish the
same with less changes. It's needed to run sync strategies in parallel,
like running `ChainSync` and `GapSync` as independent strategies, and
running `ChainSync` and Sync 2.0 alongside each other.

The difference with https://github.com/paritytech/polkadot-sdk/pull/2814
is that we allow simultaneous requests to remote peers initiated by
different strategies, as this is not tracked on the remote node in any
way. Therefore, `PeerPool` is not needed.

rpc-v2/tx: Implement `transaction_unstable_broadcast` and `transaction_unstable_stop` (#3079) · bde0bbe5

Alexandru Vasile authored Feb 12, 2024



This PR implements the
[transaction_unstable_broadcast](https://github.com/paritytech/json-rpc-interface-spec/blob/main/src/api/transaction_unstable_broadcast.md)
and
[transaction_unstable_stop](https://github.com/paritytech/json-rpc-interface-spec/blob/main/src/api/transaction_unstable_stop.md).


The
[transaction_unstable_broadcast](https://github.com/paritytech/json-rpc-interface-spec/blob/main/src/api/transaction_unstable_broadcast.md)
submits the provided transaction at the best block of the chain.
If the transaction is dropped or declared invalid, the API tries to
resubmit the transaction at the next available best block.

### Broadcasting 
The broadcasting operation continues until either:

- the user called `transaction_unstable_stop` with the operation ID that
identifies the broadcasting operation
- the transaction state is one of the following: 
  - Finalized: the transaction is part of the chain
- FinalizedTimeout: we have waited for 256 finalized blocks and timedout
  - Usurped the transaction has been replaced in the tx pool
  
The broadcasting retires to submit the transaction when the transaction
state is:
- Invalid: the transaction might become valid at a later time
- Dropped: the transaction pool's capacity is full at the moment, but
might clear when other transactions are finalized/dropped

### Stopping

The `transaction_unstable_broadcast` spawns an abortable future and
tracks the abort handler.
When the
[transaction_unstable_stop](https://github.com/paritytech/json-rpc-interface-spec/blob/main/src/api/transaction_unstable_stop.md)
is called with a valid operation ID; the abort handler of the
corresponding `transaction_unstable_broadcast` future is called. This
behavior ensures the broadcast future is finishes on the next polling.
When the `transaction_unstable_stop` is called with an invalid operation
ID, an invalid jsonrpc specific error object is returned.


### Testing

This PR adds the testing harness of the transaction API and validates
two basic scenarios:
- transaction enters and exits the transaction pool
- transaction stop returns appropriate values when called with valid and
invalid operation IDs


Closes: https://github.com/paritytech/polkadot-sdk/issues/3039

Note that the API should be enabled after:
https://github.com/paritytech/polkadot-sdk/issues/3084.

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

Oliver Tale-Yazdi authored Feb 12, 2024

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.

transaction-pool: Improve transaction status documentation and add helpers (#3215) · 4f13d5b7

Alexandru Vasile authored Feb 12, 2024



This PR improves the transaction status documentation.
- Added doc references for describing the main states
- Extra comment wrt pool ready / future queues
- `FinalityTimeout` no longer describes a lagging finality gadget, it
signals that the maximum number of finality gadgets has been reached

A few helper methods are added to indicate when:
- a final event is generated by the transaction pool for a given event
- a final event is provided, although the transaction might become valid
at a later time and could be re-submitted

The helper methods are used and taken from
https://github.com/paritytech/polkadot-sdk/pull/3079 to help us better
keep it in sync.

- Only require `Hash` instead of `Block` for the benchmarking
- Refactor DB types to do the same

## Integration

This breaking change can easily be integrated into your node via:  
```patch
- cmd.run::<Block, ()>(config)
+ cmd.run::<HashingFor<Block>, ()>(config)
```

Status: waiting for CI checks

Make BEEFY client keystore generic over BEEFY `AuthorityId` type (#2258) · 0a94124d

drskalman authored Feb 08, 2024



This is the significant step to make BEEFY client able to handle both
ECDSA and (ECDSA, BLS) type signature. The idea is having BEEFY Client
generic on crypto types makes migration to new types smoother.

This makes the BEEFY Keystore generic over AuthorityId and extends its
tests to cover the case when the AuthorityId is of type (ECDSA,
BLS12-377)
