# Description

This PR adds development chain specs for the minimal and parachain
templates.
[#6334](https://github.com/paritytech/polkadot-sdk/issues/6334)


## Integration

This PR adds development chain specs for the minimal and para chain
template runtimes, ensuring synchronization with runtime code. It
updates zombienet-omni-node.toml, zombinet.toml files to include valid
chain spec paths, simplifying configuration for zombienet in the
parachain and minimal template.

## Review Notes

1. Overview of Changes:
- Added development chain specs for use in the minimal and parachain
template.
- Updated zombienet-omni-node.toml and zombinet.toml files in the
minimal and parachain templates to include paths to the new dev chain
specs.

2. Integration Guidance:
**NB: Follow the templates' READMEs from the polkadot-SDK master branch.
Please build the binaries and runtimes based on the polkadot-SDK master
branch.**
- Ensure you have set up your runtimes `parachain-template-runtime` and
`minimal-template-runtime`
- Ensure you have installed the nodes required ie
`parachain-template-node` and `minimal-template-node`
- Set up [Zombinet](https://paritytech.github.io/zombienet/intro.html)
- For running the parachains, you will need to install the polkadot
`cargo install --path polkadot` remember from the polkadot-SDK master
branch.
- Inside the template folders minimal or parachain, run the command to
start with `Zombienet with Omni Node`, `Zombienet with
minimal-template-node` or `Zombienet with parachain-template-node`

*Include your leftover TODOs, if any, here.*
* [ ] Test the syncing of chain specs with runtime's code.

Revert https://github.com/paritytech/polkadot-sdk/pull/7011 and replace
it with a backward-compatible solution suitable for backporting to a
release branch.

### Review notes
It's easier to review this PR per commit: the first commit is just a
revert, so it's enough to review only the second one, which is almost a
one-liner.

Improve debugging by using `#[track_caller]` in system `assert_last_event` and `assert_has_event` (#7142)

Without track caller the error message of the assert points to the

I also improved the error message to include a warning when checking
events on block number zero.

`set_validation_data` register weight manually, do not use refund when the pre dispatch is zero. (#7327)

Related https://github.com/paritytech/polkadot-sdk/issues/6772

For an extrinsic, in the post dispatch info, the actual weight is only
used to reclaim unused weight. If the actual weight is more than the pre
dispatch weight, then the extrinsic is using the minimum, e.g., the
weight used registered in pre dispatch.

In parachain-system pallet one call is `set_validation_data`. This call
is returning an actual weight, but the pre-dispatch weight is 0.

This PR fix the disregard of actual weight of `set_validation_data` by
registering it manually.

The link to Polkachu is not working

This regression was introduced with some of the recent PRs. Regression
fixed and test added.

# Description

We're unable to sync templates repos with what's in
polkadot-sdk/templates for stable2412 because the tag which references
the release (`polkadot-stable2412`) is missing the Plan.toml file, which
is needed by PSVM, ran when syncing, to update the templates
dependencies versions in Cargo.tomls. This PR adds a workflow `patch`
input, to enable the workflow to use PSVM with a tag corresponding to a
patch stable release (e.g. `polkadot-stable2412-1`), which will contain
the `Plan.toml` file.

## Integration

This enables the templates repos update with the contents of latest
stable2412 release, in terms of polkadot-sdk/templates, which is
relevant for getting-started docs.

## Review Notes

This PR adds a `patch` input for the `misc-sync-templates.yml` workflow,
which if set will be used with `psvm` accordingly to update templates
repos' dependencies versions based on upcomming patch stable2412-1,
which contains the `Plan.toml`....

This PR includes minor fixes identified during work on the larger PR:
[https://github.com/paritytech/polkadot-sdk/issues/6906](https://github.com/paritytech/polkadot-sdk/issues/6906).

Specifically, this PR removes the use of
`open_bridge_between_asset_hub_rococo_and_asset_hub_westend`, which is
no longer relevant for BridgeHubs, as bridges are now created with
genesis settings. This function was used in the generic
`test_dry_run_transfer_across_pk_bridge` macro, which could cause
compilation issues when used in other contexts (e.g. fellows repo).

Currently the `para_backing_state` API is used only by the prospective
parachains subsystems and returns 2 things: the constraints for
parachain blocks and the candidates pending availability.

This PR deprecates `para_backing_state` and introduces a new
`backing_constraints` API that can be used together with
`candidates_pending_availability` to get the same information provided
by `para_backing_state`.

Fixed condition which sets weights/large images

Aims to 
- close #7049 
- close https://github.com/paritytech/opstooling/issues/449
- close https://github.com/paritytech/opstooling/issues/463

What's changed:
- removed is paritytech member check as required prerequisite to run a
command
- run the cmd.py script taking it from master, if someone who run this
is not a member of paritytech, and from current branch, if is a member.
That keeps the developer experience & easy testing if paritytech members
are contributing to cmd.py
- isolate the cmd job from being able to access GH App token or PR
token- currently the fmt/bench/prdoc are being run with limited
permissions scope, just to generate output, which then is uploaded to
artifacts, and then the other job which doesn't run any files from repo,
does a commit/push more securely

This is the right value after
https://github.com/paritytech/polkadot-sdk/pull/4880, which corresponds
to an allowedAncestryLen of 2 (which is the default)

WIll fix https://github.com/paritytech/polkadot-sdk/issues/7105

# Derived Dev Accounts

Resolves https://github.com/paritytech/polkadot-sdk/issues/6040

## Description
This update introduces support for creating an arbitrary number of
developer accounts at the genesis block based on a specified derivation
path. This functionality is gated by the runtime-benchmarks feature,
ensuring it is only enabled during benchmarking scenarios.

### Key Features
- Arbitrary Dev Accounts at Genesis: Developers can now specify any
number of accounts to be generated at genesis using a hard derivation
path.

- Default Derivation Path: If no derivation path is provided (i.e., when
`Option<dev_accounts: (..., None)>` is set to `Some` at genesis), the
system will default to the path `//Sender//{}`.

- No Impact on Total Token Issuance: Developer accounts are excluded
from the total issuance of the token supply at genesis, ensuring they do
not affect the overall balance or token distribution.

This PR contains a fix for the rc-build release pipeline. The problem
was, that for the deb package build were all the artefacts downloaded
and merged together, what could lead to the issue, that the polkadot
linux binary was overwritten with the macos one.

- Fix the EVM fee cost estimation.
The estimation shown in EVM wallet was using Native instead of EVM
decimals
- Remove the precise code length estimation in dry run call.
Over-estimating is fine, since extra gas is refunded anyway.
- Ensure that the estimated fee calculated from gas_price x gas use the
encoded weight & deposit limit instead of the exact one calculated by
the dry-run. Else we can end up with a fee that is lower than the actual
fee paid by the user

This PR enforces that outbound requests are finished within the
specified protocol timeout.

The stable2412 version running libp2p 0.52.4 contains a bug which does
not track request timeouts properly:
- https://github.com/libp2p/rust-libp2p/pull/5429

The issue has been detected while submitting libp2p -> litep2p requests
in kusama. This aims to check that pending outbound requests have not
timedout. Although the issue has been fixed in libp2p, there might be
other cases where this may happen. For example:
- https://github.com/libp2p/rust-libp2p/pull/5417

For more context see:
https://github.com/paritytech/polkadot-sdk/issues/7076#issuecomment-2596085096


1. Ideally, the force-timeout mechanism in this PR should never be
triggered in production. However, origin/stable2412 occasionally
encounters this issue. When this happens, 2 warnings may be generated:
- one warning introduced by this PR wrt force timeout terminating the
request
- possible one warning when the libp2p decides (if at all) to provide
the response back to substrate (as mentioned by @alexggh
[here](https://github.com/paritytech/polkadot-sdk/pull/7222/files#diff-052aeaf79fef3d9a18c2cfd67006aa306b8d52e848509d9077a6a0f2eb856af7L769)
and
[here](https://github.com/paritytech/polkadot-sdk/pull/7222/files#diff-052aeaf79fef3d9a18c2cfd67006aa306b8d52e848509d9077a6a0f2eb856af7L842)

2. This implementation does not propagate to the substrate service the
`RequestFinished { error: .. }`. That event is only used internally by
substrate to increment metrics. However, we don't have the peer
information available to propagate the event properly when we
force-timeout the request. Considering this should most likely not
happen in production (origin/master) and that we'll be able to extract
information by warnings, I would say this is a good tradeoff for code
simplicity:


https://github.com/paritytech/polkadot-sdk/blob/06e3b5c6

/substrate/client/network/src/service.rs#L1543


### Testing

Added a new test to ensure the timeout is reached properly, even if
libp2p does not produce a response in due time.

I've also transitioned the tests to using `tokio::test` due to a
limitation of
[CI](https://github.com/paritytech/polkadot-sdk/actions/runs/12832055737/job/35784043867)

## Issue
[[#7107] Core Index Mismatch in Commitments and
Descriptor](https://github.com/paritytech/polkadot-sdk/issues/7107)

## Description
This PR resolves a bug where normal (non-malus) undying collators failed
to generate and submit collations, resulting in the following error:

`ERROR tokio-runtime-worker parachain::collation-generation: Failed to
construct and distribute collation: V2 core index check failed: The core
index in commitments doesn't match the one in descriptor.`

More details about the issue and reproduction steps are described in the
[related issue](https://github.com/paritytech/polkadot-sdk/issues/7107).

## Summary of Fix
- When core selectors are provided in the UMP signals, core indexes will
be chosen using them;
- The fix ensures that functionality remains unchanged for parachains
not using UMP signals;
- Added checks to stop processing if the same core is selected
repeatedly.

## TODO
- [X] Implement the fix;
- [x] Add tests;
- [x] Add PRdoc.

## Description

The `frame-benchmarking-cli` crate has not been buildable without the
`rocksdb` feature since version 1.17.0.

**Error:**  
```rust
self.database()?.unwrap_or(Database::RocksDb),
                             ^^^^^^^ variant or associated item not found in `Database`
```

This issue is also related to the `rocksdb` feature bleeding (#3793),
where the `rocksdb` feature was always activated even when compiling
this crate with `--no-default-features`.

**Fix:**  
- Resolved the error by choosing `paritydb` as the default database when
compiled without the `rocksdb` feature.
- Fixed the issue where the `sc-cli` crate's `rocksdb` feature was
always active, even compiling `frame-benchmarking-cli` with
`--no-default-features`.

## Review Notes

Fix the crate to be built without rocksdb, not intended to solve #3793.
