Sometimes you need to debug some issues just by the logs and reconstruct
what happened.
In these scenarios it would be nice to know if a block was imported as
best block, and what it parent was.
So here I propose to change the output of the informant to this:

## Basic example showcasing a migration using the MBM framework
This PR has been built on top of
https://github.com/paritytech/polkadot-sdk/pull/1781 and adds two new
example crates to the `examples` pallet
### Changes Made:
Added the `pallet-example-mbm` crate: This crate provides a minimal
example of a pallet that uses MBM. It showcases a storage migration
where values are migrated from a `u32` to a `u64`.

This PR ensure that the distance between any leaf and the finalized
block is within a reasonable distance.
For a new subscription, the chainHead has to provide all blocks between
the leaves of the chain and the finalized block.
When the distance between a leaf and the finalized block is large:
- The tree route is costly to compute
- We could deliver an unbounded number of blocks (potentially millions)
(For more details see
https://github.com/paritytech/polkadot-sdk/pull/3445#discussion_r1507210283)
The configuration of the ChainHead is extended with:
- suspend on lagging distance: When the distance between any leaf and
the finalized block is greater than this number, the subscriptions are
suspended for a given duration.
- All active subscriptions are terminated with the `Stop` event, all
blocks are unpinned and data discarded.
- For incoming subscriptions, until the suspended period expires the
subscriptions will immediately receive the `Stop` event.
- Defaults to 128 blocks
- suspended duration: The amount of time for which subscriptions are
suspended
- Defaults to 30 seconds

closes#1324
#### Problem
Currently, it is possible to accidentally use inner unversioned
migration instead of `VersionedMigration` since both implement
`OnRuntimeUpgrade`.
#### Solution
With this change, we make it clear that value of `Inner` is not intended
to be used directly. It is achieved by bounding `Inner` to new trait
`UncheckedOnRuntimeUpgrade`, which has the same interface (except
`unchecked_` prefix) as `OnRuntimeUpgrade`.
#### `try-runtime` functions
Since developers can implement `try-runtime` for `Inner` value in
`VersionedMigration` and have custom logic for it, I added the same
`try-runtime` functions to `UncheckedOnRuntimeUpgrade`. I looked for a
ways to not duplicate functions, but couldn't find anything that doesn't
significantly change the codebase. So I would appreciate If you have any
suggestions to improve this

Working towards migrating the `parity-bridges-common` repo inside

This PR ensures that the chainHead RPC class can be called only from
within the same connection context.
The chainHead methods are now registered as raw methods.
- https://github.com/paritytech/jsonrpsee/pull/1297
The concept of raw methods is introduced in jsonrpsee, which is an async
method that exposes the connection ID:
The raw method doesn't have the concept of a blocking method. Previously
blocking methods are now spawning a blocking task to handle their
blocking (ie DB) access. We spawn the same number of tasks as before,
however we do that explicitly.
Another approach would be implementing a RPC middleware that captures
and decodes the method parameters:
- https://github.com/paritytech/polkadot-sdk/pull/3343
However, that approach is prone to errors since the methods are
hardcoded by name. Performace is affected by the double deserialization
that needs to happen to extract the subscription ID we'd like to limit.
Once from the middleware, and once from the methods itself.
This PR paves the way to implement the chainHead connection limiter:
- https://github.com/paritytech/polkadot-sdk/issues/1505
Registering tokens (subscription ID / operation ID) on the
`RpcConnections` could be extended to return an error when the maximum
number of operations is reached.
While at it, have added an integration-test to ensure that chainHead
methods can be called from within the same connection context.
Before this is merged, a new JsonRPC release should be made to expose
the `raw-methods`:

derive-syn-parse v0.2.0 came out recently which (finally) adds support
for syn 2x.
Upgrading to this will remove many of the places where syn 1x was still
compiling alongside syn 2x in the polkadot-sdk workspace.
This also upgrades `docify` to 0.2.8 which is the version that upgrades
derive-syn-pasre to 0.2.0.
Additionally, this consolidates the `docify` versions in the repo to all
use the latest, and in one case upgrades to the 0.2x syntax where 0.1.x
was still being used.

Related Issue https://github.com/paritytech/polkadot-sdk/issues/3398
This PR makes permissionless withdrawing the default option, giving any
network participant access to claim pool rewards on member's behalf. Of
course, members can still opt out of this by setting a `Permissioned`
claim permission.
Permissionless claiming has been a part of the nomination pool pallet
for around 9 months now, with very limited uptake (~4% of total pool
members). 1.6% of pool members are using `PermissionlessAll`, strongly
suggesting it is not wanted - it is too ambiguous and doesn't provide
guidance to claimers.
Stakers expect rewards to be claimed on their behalf by default - I have
expanded upon this in detail within the [accompanying issue's
discussion](https://github.com/paritytech/polkadot-sdk/issues/3398).
Other protocols have this behaviour, whereby staking rewards are
received without the staker having to take any action. From this
perspective, permissionless claiming is not intuitive for pool members.
As evidence of this, over 150,000 DOT is currently unclaimed on
Polkadot, and is growing at a non-linear rate.

Currently, all protocols use the same metric name for
`mpsc-notification-to-protocol` this is bad because we can't actually
tell which protocol might cause problems.
This patch proposes we derive the name of the metric from the protocol
name, so that we have separate metrics for each protocol and properly
detect which one is having problem processing its messages.

This PR significantly refactors the runtime API implementations to
improve project structure, maintainability, and readability. Key changes
include:
1. **Enhancing Visibility**: Adjusts the visibility of
`RUNTIME_API_VERSIONS` in `impl_runtime_apis.rs` to `pub`, making it
accessible throughout the runtime module.
2. **Centralizing API Implementations**: Introduces a new file,
`apis.rs`, within the parachain template's runtime directory.
3. **Streamlining `lib.rs`**: Updates the main runtime library file to
reflect these structural changes. It removes redundant API
implementations and points `VERSION` to the newly exposed
`RUNTIME_API_VERSIONS` from `apis.rs`, simplifying the overall runtime
configuration.
### Motivations Behind the Refactoring:
- **Improved Project Structure**: Centralizing API implementations in
`apis.rs` offers a clearer, more navigable project structure.
- **Better Readability**: Streamlining `lib.rs` and reducing clutter
enhance readability, making it easier for new contributors to understand
the project layout and logic.
### Summary of Changes:
- Made `RUNTIME_API_VERSIONS` public in `impl_runtime_apis.rs`.
- Added `apis.rs` to centralize runtime API implementations.
- Streamlined `lib.rs` to adjust to the refactored project structure.

There has been a case that a referenda failed because the length given
to `submit` was incorrect. The pallet can actually check the length if
the pre-image already exists to ensure that these kind of issues are not
happening again.
This PR adds a new extrinsic `Call::restore_ledger ` gated by
`StakingAdmin` origin that restores a corrupted staking ledger. This
extrinsic will be used to recover ledgers that were affected by the
issue discussed in
https://github.com/paritytech/polkadot-sdk/issues/3245.
The extrinsic will re-write the storage items associated with a stash
account provided as input parameter. The data used to reset the ledger
can be either i) fetched on-chain or ii) partially/totally set by the
input parameters of the call.
In order to use on-chain data to restore the staking locks, we need a
way to read the current lock in the balances pallet. This PR adds a
`InspectLockableCurrency` trait and implements it in the pallet
balances. An alternative would be to tightly couple staking with the
pallet balances but that's inelegant (an example of how it would look
like in [this
branch](https://github.com/paritytech/polkadot-sdk/tree/gpestana/ledger-badstate-clean_tightly)).
More details on the type of corruptions and corresponding fixes
https://hackmd.io/DLb5jEYWSmmvqXC9ae4yRg?view#/
We verified that the `Call::restore_ledger` does fix all current
corrupted ledgers in Polkadot and Kusama. You can verify it here
https://hackmd.io/v-XNrEoGRpe7APR-EZGhOA.
**Changes introduced**
- Adds `Call::restore_ledger ` extrinsic to recover a corrupted ledger;
- Adds trait `frame_support::traits::currency::InspectLockableCurrency`
to allow external pallets to read current locks given an account and
lock ID;
- Implements the `InspectLockableCurrency` in the pallet-balances.
- Adds staking locks try-runtime checks
(https://github.com/paritytech/polkadot-sdk/issues/3751)
**Todo**
- [x] benchmark `Call::restore_ledger`
- [x] throughout testing of all ledger recovering cases
- [x] consider adding the staking locks try-runtime checks to this PR
(https://github.com/paritytech/polkadot-sdk/issues/3751)
- [x] simulate restoring all ledgers

The authority-discovery mechanism has implemented a few exponential
timers for:
- publishing the authority records
- goes from 2 seconds (when freshly booted) to 1 hour if the node is
long-running
- set to 1 hour after successfully publishing the authority record
- discovering other authority records
- goes from 2 seconds (when freshly booted) to 10 minutes if the node is
long-running
This PR resets the exponential publishing and discovery interval to
defaults ensuring that long-running nodes:
- will retry publishing the authority records as aggressively as freshly
booted nodes
- Currently, if a long-running node fails to publish the DHT record when
the keys change (ie DhtEvent::ValuePutFailed), it will only retry after
1 hour
- will rediscover other authorities faster (since there is a chance that
other authority keys changed)
The subp2p-explorer has difficulties discovering the authorities when
the authority set changes in the first few hours. This might be entirely
due to the recursive nature of the DHT and the needed time to propagate
the records. However, there is a small chance that the authority
publishing failed and is only retried in 1h.
Let me know if this makes sense 🙏
