# Description

This seems to be an old artifact of the long closed
paritytech/substrate#6827 that I noticed when
working on related code earlier.

## Integration

`NetworkStarter` was removed, simply remove its usage:
```diff
-let (network, system_rpc_tx, tx_handler_controller, start_network, sync_service) =
+let (network, system_rpc_tx, tx_handler_controller, sync_service) =
    build_network(BuildNetworkParams {
...
-start_network.start_network();
```

## Review Notes

Changes are trivial, the only reason for this to not be accepted is if
it is desired to not start network automatically for whatever reason, in
which case the description of network starter needs to change.

This PR adds size-limits to the fork-aware transaction pool.

**Review Notes**
- Existing
[`TrackedMap`](https://github.com/paritytech/polkadot-sdk/blob/58fd5ae4ce883f42c360e3ad4a5df7d2258b42fe/substrate/client/transaction-pool/src/graph/tracked_map.rs#L33-L41)
is used in internal mempool to track the size of extrinsics:

- In this PR, I also removed the logic that kept transactions in the
`tx_mem_pool` if they were immediately dropped by the views. Initially,
I implemented this as an improvement: if there was available space in
the _mempool_ and all views dropped the transaction upon submission, the
transaction would still be retained in the _mempool_.

However, upon further consideration, I decided to remove this
functionality to reduce unnecessary complexity. Now, when all views drop
a transaction during submission, it is automatically rejected, with the
`submit/submit_and_watch` call returning `ImmediatelyDropped`.

There is no need to verify in the `pallet-membership` benchmark that the
`MemembershipChanged` implementation works as the pallet thinks it
should work. If you for example set it to `()`, `get_prime()` will
always return `None`.

TLDR: Remove the checks of `MembershipChanged` in the benchmarks to

… adaptable (#6425)

# Description

Resolves #6193

This PR introduces `ConstUint` as a replacement for existing constant
getter types like `ConstU8`, `ConstU16`, etc., providing a more flexible
and unified approach.

## Integration

This update is backward compatible, so developers can choose to adopt
`ConstUint` in new implementations or continue using the existing types
as needed.

## Review Notes

`ConstUint` is a convenient alternative to `ConstU8`, `ConstU16`, and
similar types, particularly useful for configuring `DefaultConfig` in
pallets. It enables configuring the underlying integer for a specific
type without the need to update all dependent types, offering enhanced
flexibility in type management.

This PR fixes an issue that I discovered using connecting to the RPC via
localhost using cURL, where cURL tries to connect to via ipv6 before
ipv4 when querying `localhost` which messed up the http host filter
whereas it would connect to the address `[::1]::9944 host_header:
localhost:9944` but the ipv6 interface only whitelisted `[::1]:9944`
which this fixes.

So let's whitelist all localhost interfaces to avoid such weird
edge-cases.

…tionExtension::validate` (#6323)

## Meta 

This PR is part of 4 PR:
* #6323
* #6324
* #6325
* #6326

## Description

One goal of transaction extension is to get rid or unsigned
transactions.
But unsigned transaction validation has access to the
`TransactionSource`.

The source is used for unsigned transactions that the node trust and
don't want to pay upfront.
Instead of using transaction source we could do: the transaction is
valid if it is signed by the block author, conceptually it should work,
but it doesn't look so easy.

This PR add `TransactionSource` to the validate function for transaction
extensions

# Description

Part of #3326
Removes all pallet::getter occurrences from pallet-staking and replaces
them with explicit implementations.
Adds tests to verify that retrieval of affected entities works as
expected so via storage::getter.

## Review Notes

1. Traits added to the `derive` attribute are used in tests (either
directly or indirectly).
2. The getters had to be placed in a separate impl block since the other
one is annotated with `#[pallet::call]` and that requires
`#[pallet::call_index(0)]` annotation on each function in that block. So
I thought it's better to separate them.

When using multiple instances of the same pallet, each instance was
executed with the components of all instances. While actually each
instance should only be executed with the components generated for the
particular instance. The problem here was that in the runtime only the
pallet-name was used to determine if a certain pallet should be
benchmarked. When using instances, the pallet name is the same for both
of these instances. The solution is to also take the instance name into
account.

The fix requires to change the `Benchmark` runtime api to also take the
`instance`. The node side is written in a backwards compatible way to
also support runtimes which do not yet support the `instance` parameter.

## Issue
[[#3421] backing: improve session buffering for runtime
information](#3421)

## Description
In the current implementation of the backing module, certain pieces of
information, which remain unchanged throughout a session, are fetched
multiple times via runtime API calls. The goal of this task was to
introduce a local cache to store such session-stable information and
perform the runtime API call only once per session.

This PR implements caching specifically for the validators list, node
features, executor parameters, minimum backing votes threshold, and
validator-to-group mapping, which were previously fetched from the
runtime or computed each time `PerRelayParentState` was built. Now, this
information is cached and reused within the session.

## TODO
* [X] Create a separate struct for per-session caches;
* [X] Cache validators list;
* [X] Cache node features;
* [X] Cache executor parameters;
* [X] Cache minimum backing votes threshold;
* [X] Cache validator-to-group mapping;
* [X] Update tests to reflect these changes;
* [X] Add prdoc.

## For the next PR
Cache validator groups and any other session-stable data (if present).

Partially fixes #6403

The main PR introduced bare support for the new extension version byte

This PR:
- Removes the redundant extension version byte from the signed v4
extrinsic, previously unused and defaulted to 0.
- Adds the extension version byte to the inherited implication passed to
`General` transactions.
- Whitelists the `pallet_authorship::Author`, `frame_system::Digest` and
`pallet_transaction_payment::NextFeeMultiplier` storage items as they
are read multiple times by extensions for each transaction, but are hot
in memory and currently overestimate the weight.
- Whitelists the benchmark caller for `CheckEra` and `CheckGenesis` as
the reads are performed for every transaction and overestimate the
weight.
- Updates the umbrella frame weight template to work with the system
extension changes.
- Plans on re-running the benchmarks at least for the `frame_system`
extensions.

# Description

Created a workflow to search for README.docify.md in the repo, and run
cargo build --features generate-readme in the dir of the file (assuming
it is related to a crate). If the git diff shows some output for the
README.md, then the file update wasn't pushed on the branch, and the
workflow fails.
Closes #6331

## Integration

Downstream projects that want to adopt this README checking workflow
should:

1. Copy the `.github/workflows/readme-check.yml` file to their
repository
2. Ensure any `README.docify.md` files in their project follow the
expected format
3. Implement the `generate-readme` feature flag in their Cargo.toml if
not already present

## Review Notes

This PR adds a GitHub Actions workflow that automatically verifies
README.md files are up-to-date with their corresponding README.docify.md
sources. Key implementation details:

- The workflow runs on both PRs and pushes to main
- It finds all `README.docify.md` files recursively in the repository
- For each file found:
- Builds the project with `--features generate-readme` in that directory
  - Checks if the README.md has any uncommitted changes
  - Fails if any README.md is out of sync

It doesn't make sense to only reorder the features array.

This makes it hard for me to compare the dependencies and features,

```toml​

c = "*"
a = "*"
b = "*"

[features]
std = [
  "a",
  "b",
  "c",
]
```

This makes my life easier.

… to wait two sale boundaries (#4273)

When calling the reserve extrinsic after sales have started, the
assignment will be reserved, but two sale period boundaries must pass
before the core is actually assigned.

Since this can take between 28 and 56 days on production networks, a new
extrinsic is introduced to shorten the timeline.

This essentially performs three actions:
1. Reserve it (applies after two sale boundaries)
2. Add it to the Workplan for the next sale period
3. Add it to the Workplan for the rest of the current sale period from
the next timeslice to be commmitted.

The caller must ensure that a core is first added, with most relay chain
implementations having a delay of two session boundaries until it comes
into effect.

Alternatively the extrinsic can be called on a core whose workload can
be clobbered from now until the reservation kicks in (the sale period
after the next). Any workplan entries for that core at other timeslices
should be first removed by the caller.

# Description

Migrate pallet-mixnet to use umbrella crate whilst adding a few types
and traits in the frame prelude that are used by other pallets as well.

## Review Notes

* This PR migrates `pallet-mixnet` to use the umbrella crate. 
* Note that some imports like `use
sp_application_crypto::RuntimeAppPublic;` and imports from
`sp_mixnet::types::` have not been migrated to the umbrella crate as
they are not used in any / many other places and are relevant only to
the `pallet-mixnet`.
* Transaction related helpers to submit transactions from `frame-system`
have been added to the main `prelude` as they have usage across various
pallets.
```Rust
	pub use frame_system::offchain::*;
```
* Exporting `arithmetic` module in the main `prelude` since this is used
a lot throughout various pallets.
* Nightly formatting has been applied using `cargo fmt`
* Benchmarking dependencies have been removed from`palet-mixnet` as
there is no benchmarking.rs present for `pallet-mixnet`. For the same
reason, `"pallet-mixnet?/runtime-benchmarks"` has been removed from
`umbrella/Cargo.toml`.

#7028)

Currently `(A, B, C)` and `((A, B), C)` change the order of implications
in the transaction extension pipeline. This order is not accessible in
the metadata, because the metadata is just a vector of transaction
extension, the nested structure is not visible.

This PR make the implementation for tuple of `TransactionExtension`
better for tuple of tuple. `(A, B, C)` and `((A, B), C)` don't change
the implication for the validation A.

This is a breaking change but only when using the trait
`TransactionExtension` the code implementing the trait is not breaking
(surprising rust behavior but fine).
