# Description

**Understood assignment:**
Initial assignment description is in #6194.
In order to Simplify the display of commands and ensure they are tested
for chain spec builder's `polkadot-sdk` reference docs, find every
occurrence of `#[docify::export]` where `process:Command` is used, and
replace the use of `process:Command` by `run_cmd!` from the `cmd_lib
crate`.

## Description

With [permissionless lanes
PR#4949](https://github.com/paritytech/polkadot-sdk/pull/4949), the
congestion mechanism based on sending
`Transact(report_bridge_status(is_congested))` from
`pallet-xcm-bridge-hub` to `pallet-xcm-bridge-hub-router` was replaced
with a congestion mechanism that relied on monitoring XCMP queues.
However, this approach could cause issues, such as suspending the entire
XCMP queue instead of isolating the affected bridge. This PR reverts
back to using `report_bridge_status` as before.

Last feature we wanted for V5, changing `SetAssetClaimer` to be just one
of many possible "hints" that you can specify at the beginning of your
program to change its behaviour.

This makes it easier to add new hints in the future and have barriers

* Add a bunch of differential tests to ensure that responses from
eth-rpc matches the one from `geth`
- These
[tests](https://github.com/paritytech/polkadot-sdk/blob/pg/fix-geth-diff/substrate/frame/revive/rpc/examples/js/src/geth-diff.test.ts)
are not run in CI for now but can be run locally with
```bash
cd revive/rpc/examples/js
bun test
```

* EVM RPC server will not fail gas_estimation if no gas is specified, I
updated pallet-revive to add an extra `skip_transfer` boolean check to
replicate this behavior in our pallet

* `eth_transact` and `bare_eth_transact` api have been updated to use
`GenericTransaction` directly as this is what is used by
`eth_estimateGas` and `eth_call`

## TODO

# Description

Updates scale-info to from 2.11.5 2.11.6, so that generated code is
annotated with `allow(deprecated)`
Pre-requisite for https://github.com/paritytech/polkadot-sdk/pull/6312

Construct runtime uses autoref-based specialization to fetch the
metadata about the implemented runtime apis. This is done to not fail to
compile when there are no runtime apis implemented. However, there was
an issue with detecting runtime apis when they were implemented in a
different file. The problem is solved by moving the trait implemented by
`impl_runtime_apis!` to the metadata ir crate.

This PR updates pallet_revive to the newest PolkaVM version and adapts
the test fixtures and syscall interface to work under 64bit.

Please note that after this PR no 32bit contracts can be deployed (they
will be rejected at deploy time). Pre-deployed 32bit contracts are now
considered defunct since we changes how parameters are passed for
functions with more than 6 arguments.

## Fixtures

The fixtures are now built for the 64bit target. I also removed the
temporary directory mechanism that triggered a full rebuild every time.
It also makes it easier to find the compiled fixtures since they are now
always in `target/pallet-revive-fixtures`.

## Syscall interface

### Passing pointer

Registers and pointers are now 64bit wide. This allows us to pass u64
arguments in a single register. Before we needed two registers to pass
them. This means that just as before we need one register per pointer we
pass. We keep pointers as `u32` argument by truncating the register.
This is done since the memory space of PolkaVM is 32bit.

### Functions with more than 6 arguments

We only have 6 registers to pass arguments. This is why we pass a
pointer to a struct when we need more than 6. Before this PR we expected
a packed struct and interpreted it as SCALE encoded tuple. However, this
was buggy because the `MaxEncodedLen` returned something that was larger
than the packed size of the structure. This wasn't a problem before. But
now the memory space changed in a way that things were placed at the
edges of the memory space and those extra bytes lead to an out of bound
access.

This is why this PR drops SCALE and expects the arguments to be passed
as a pointer to a `C` aligned struct. This avoids unaligned accesses.
However, revive needs to adapt its codegen to properly align the
structure fields.

## TODO
- [ ] Add multi block migration that wipes all existing contracts as we
made breaking changes to the syscall interface

This includes a critical fix for debug release versions of litep2p
(which are running in Kusama as validators).

While at it, have stopped the oncall pain of alerts around
`incoming_connections_total`. We can rethink the metric expose of
litep2p in Q1.





## [0.8.2] - 2024-11-27

This release ensures that the provided peer identity is verified at the
crypto/noise protocol level, enhancing security and preventing potential
misuses.
The release also includes a fix that caused `TransportService` component
to panic on debug builds.

### Fixed

- req-resp: Fix panic on connection closed for substream open failure
([#291](https://github.com/paritytech/litep2p/pull/291))
- crypto/noise: Verify crypto/noise signature payload
([#278](https://github.com/paritytech/litep2p/pull/278))

### Changed

- transport_service/logs: Provide less details for trace logs
([#292](https://github.com/paritytech/litep2p/pull/292))


## Testing Done

This has been extensively tested in Kusama...

This PR implements the `archive_unstable_storageDiff`.

This PR exposes the *unstable* metadata V16. The metadata is exposed
under the unstable u32::MAX number.

Developers can start experimenting with the new features of the metadata
v16. *Please note that this metadata is under development and expect
breaking changes until stabilization.*

The `ExtrinsicMetadata` trait receives a breaking change. Its associated
type `VERSION` is rename to `VERSIONS` and now supports a constant
static list of metadata versions.
The versions implemented for `UncheckedExtrinsic` are v4 (legacy
version) and v5 (new version).

For metadata collection, it is assumed that all `TransactionExtensions`
are under version 0.

The `query_weight_to_asset_fee` function was trying to convert versions
by using `try_as`, this function [doesn't convert from a versioned to a
concrete
type](https://github.com/paritytech/polkadot-sdk/blob/0156ca8f/polkadot/xcm/src/lib.rs#L131).
This would cause all calls with a lower version to fail.

The correct function to use is the good old
[try_into](https://github.com/paritytech/polkadot-sdk/blob/0156ca8f

/polkadot/xcm/src/lib.rs#L184).
Now those calls work :)

Before this was done for every imported transaction. When a lot of
transactions got imported, the import notification channel was filled.
The underlying problem was that the `status` call is read locking the
`validated_pool` which will be write locked by the internal submitting
logic. Thus, the submitting and status reading was interferring which
each other.

This PR updates the litep2p backend to version 0.8.1 from 0.8.0.
- Check the [litep2p updates forum
post](https://forum.polkadot.network/t/litep2p-network-backend-updates/9973/3)
for performance dashboards.
- Check [litep2p release
notes](https://github.com/paritytech/litep2p/pull/288)

The v0.8.1 release includes key fixes that enhance the stability and
performance of the litep2p library. The focus is on long-running
stability and improvements to polling mechanisms.

### Long Running Stability Improvements

This issue caused long-running nodes to reject all incoming connections,
impacting overall stability.

Addressed a bug in the connection limits functionality that incorrectly
tracked connections due for rejection.

This issue caused an artificial increase in inbound peers, which were
not being properly removed from the connection limit count.

This fix ensures more accurate tracking and management of peer
connections [#286](https://github.com/paritytech/litep2p/pull/286).

### Polling implementation fixes

This release provides multiple fixes to the polling mechanism, improving
how connections and events are processed:
- Resolved an overflow issue in TransportContext’s polling index for
streams, preventing potential crashes
([#283](https://github.com/paritytech/litep2p/pull/283)).
- Fixed a delay in the manager’s poll_next function that prevented
immediate polling of newly added futures
([#287](https://github.com/paritytech/litep2p/pull/287)).
- Corrected an issue where the listener did not return Poll::Ready(None)
when it was closed, ensuring proper signal handling
([#285](https://github.com/paritytech/litep2p/pull/285)).


### Fixed

- manager: Fix connection limits tracking of rejected connections
([#286](https://github.com/paritytech/litep2p/pull/286))
- transport: Fix waking up on filtered events from `poll_next`
([#287](https://github.com/paritytech/litep2p/pull/287))
- transports: Fix missing Poll::Ready(None) event from listener
([#285](https://github.com/paritytech/litep2p/pull/285))
- manager: Avoid overflow on stream implementation for
`TransportContext`
([#283](https://github.com/paritytech/litep2p/pull/283))
- manager: Log when polling returns Ready(None)
([#284](https://github.com/paritytech/litep2p/pull/284))


### Testing Done

Started kusama nodes running side by side with a higher number of
inbound and outbound connections (500).
We previously tested with peers bounded at 50. This testing filtered out
the fixes included in the latest release.

With this high connection testing setup, litep2p outperforms libp2p in
almost every domain, from performance to the warnings / errors
encountered while operating the nodes.

TLDR: this is the version we need to test on kusama validators next

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.

# 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.

# Description

Implemented benchmarks for Notifications and RequestResponse protocols
with libp2p implementation. These benchmarks allow us to monitor
regressions and implement fixes before they are observed in real chain.
In the future, they can be used for targeted optimizations of litep2p
compared to libp2p.

Part of https://github.com/paritytech/polkadot-sdk/issues/5220

Next steps:
- Add benchmarks for litep2p implementation
- Optimize load to get better results
- Add benchmarks to CI to catch regressions



## Integration

Benchmarks don't affect downstream projects.

Fixes https://github.com/paritytech/polkadot-sdk/issues/5530

This PR introduces the removal of backing jobs that have been back
pressured for longer than `allowedAncestryLen`, as these candidates are
no longer viable.

It is reasonable to expect a result for a backing job execution within
`allowedAncestryLen` blocks. Therefore, we set the job TTL as a relay
block number and synchronize the validation host by sending activated
leaves.

The tests used the same paths. When run on CI, each test is run in its
own process and thus, this "serial_test" crate wasn't used. The tests
are now using their own thread local tempdir, which ensures that the
tests are working when running in parallel in the same program or when
being run individually.

# Description

Closes #5940  

## Integration

Node devs that rely on templates' nodes binaries for minimal or
parachain would need to follow the updated templates' README.mds again
to find how to build the nodes' binaries.

## Review Notes

Conditional compilation of virtual workspaces would compile the
`members` list as if we passed `--workspace` flag to `cargo build` ,
except when adding a `default-members` list which will be used for any
cargo command executed in the virtual workspace root. To build the full
members list needs passing `--workspace` flag.

Other options investigated:
- feature guard the `node` crate by defining a feature in the `node`
crate, but it feels too complex since all code needs to be feature
guarded. I haven't tried it but technically speaking it might work. I
think though it looks awkward and my opinion is that the alternative is
better.
- defining features in the virtual workspace's Cargo.toml doesn't work
(thought that I might create a feature that will have a dependency on
the `node` crate and then not passing the feature to cargo build results
in ignoring the `node` crate)
- skipping compilation by using an environment variable, read in the
build script, that will exit compilation abruptly if not set, but I
couldn't make it work.
- exclude the crate from the members list and build it specifically by
passing `--package minimal-template-node` flag to the `cargo build`
command. This has the disadvantage of not allowing IDEs based on rust
analyzer to index/compile the node crate.

My conclusion is that any option would require two commands to build the
template, one with the node and one without, and both must be included
in the README or templates usage documentation. If it comes which ones
to pick I am in favor of the `default-members` option, which requires
minimal intervention and expresses how cargo commands are executed on
top of the workspace members, and what's left out from regular usage.

### Testing

Testing was conducted as described bellow:

- [x] zombienet with `minimal-template-node` , `parachain-template-node`
and `polkadot-omni-node`. Things work as expected.
- [x] no chopsticks testing was conducted - feels a bit out of scope for
OmniNode related docs and overall testing when promoting it over the
templates' nodes.
- [x] testing the changes for the sync templates workflow (ignore the
added comment from the Cargo.tomls, it was removed here on this branch:
[99bff3e2](https://github.com/paritytech/polkadot-sdk/pull/5954/commits/99bff3e2

)):

The links correspond to PRs opened by a bot after manually starting the
sync-templates workflow on `paritytech-stg` org to test the end result
of the `Cargo.toml` changes.
