      Replace homepage in all TOML files (#5118) · d3d1542c

      A bit of a controversial move, but a good preparation for even further
reducing the traffic on outdated content of `substrate.io`. Current
status:

Previously, I was in favor of changing the domain of the rust-docs to
something like `polkadot-sdk.parity.io` or similar, but I think the
current format is pretty standard and has a higher chance of staying put
over the course of time:

      Remove most all usage of `sp-std` (#5010) · 7ecf3f75
      Jun Jiang authored 
      
This should remove nearly all usage of `sp-std` except:
- bridge and bridge-hubs
- a few of frames re-export `sp-std`, keep them for now
- there is a usage of `sp_std::Writer`, I don't have an idea how to move
it

Please review proc-macro carefully. I'm not sure I'm doing it the right
way.

Note: need `/bot fmt`

      Lift all dependencies (the big one) (#4716) · 8efa0544
      Oliver Tale-Yazdi authored 
      
After preparing in https://github.com/paritytech/polkadot-sdk/pull/4633,
we can lift also all internal dependencies up to the workspace.

This does not actually change anything, but uses `workspace = true` for
all dependencies. You can check it with:
```bash
git checkout -q $(git merge-base oty-lift-all-deps origin/master)
cargo tree -e features > master.out

git checkout -q oty-lift-all-deps
cargo tree -e features > new.out
diff master.out new.out
```

It did not yet lift 100% of dependencies, some inside of `target.*` or
some that had conflicting aliases introduced recently. But i will do
these together in a follow-up with CI checks.

Can be reproduced with [zepter](https://github.com/ggwpez/zepter/):
`zepter transpose d lift-to-workspace "regex:.*" --version-resolver
highest --skip-package "polkadot-sdk" --ignore-errors --fix`.

      Branislav Kontur authored 
      Attempt to avoid specifying `BlockHashCount` for different `mocking::{MockBlock, MockBlockU32, MockBlockU128}` (#4543)

While doing some migration/rebase I came in to the situation, where I
needed to change `mocking::MockBlock` to `mocking::MockBlockU32`:
```
#[derive_impl(frame_system::config_preludes::TestDefaultConfig)]
impl frame_system::Config for TestRuntime {
	type Block = frame_system::mocking::MockBlockU32<TestRuntime>;
	type AccountData = pallet_balances::AccountData<ThisChainBalance>;
}
```
But actual `TestDefaultConfig` for `frame_system` is using `ConstU64`
for `type BlockHashCount = frame_support::traits::ConstU64<10>;`
[here](https://github.com/paritytech/polkadot-sdk/blob/master/substrate/frame/system/src/lib.rs#L303).
Because of this, it force me to specify and add override for `type
BlockHashCount = ConstU32<10>`.

This PR tries to fix this with `TestBlockHashCount` implementation for
`TestDefaultConfig` which supports `u32`, `u64` and `u128` as a
`BlockNumber`.

### How to simulate error
Just by removing `type BlockHashCount = ConstU32<250>;`
[here](https://github.com/paritytech/polkadot-sdk/blob/master/substrate/frame/multisig/src/tests.rs#L44)
```

## For reviewers:

(If there is a better solution, please let me know!)

The first commit contains actual attempt to fix the problem:
https://github.com/paritytech/polkadot-sdk/commit/3c5499e5

.
The second commit is just removal of `BlockHashCount` from all other
places where not needed by default.

Closes: https://github.com/paritytech/polkadot-sdk/issues/1657

      Liam Aharon authored 
      Closes https://github.com/paritytech/polkadot-sdk-docs/issues/55

- Changes 'current storage version' terminology to less ambiguous
'in-code storage version' (suggestion by @ggwpez

)
- Adds a new example pallet `pallet-example-single-block-migrations`
- Adds a new reference doc to replace
https://docs.substrate.io/maintain/runtime-upgrades/ (temporarily living
in the pallet while we wait for developer hub PR to merge)
- Adds documentation for the `storage_alias` macro
- Improves `trait Hooks` docs 
- Improves `trait GetStorageVersion` docs
- Update the suggested patterns for using `VersionedMigration`, so that
version unchecked migrations are never exported
- Prevents accidental usage of version unchecked migrations in runtimes

https://github.com/paritytech/substrate/pull/14421#discussion_r1255467895
- 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

      Oliver Tale-Yazdi authored 
      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.

      [frame] `#[pallet::composite_enum]` improved variant count handling + removed `pallet_balances`'s `MaxHolds` config (#2657)

I started this investigation/issue based on @liamaharon question
[here](https://github.com/paritytech/polkadot-sdk/pull/1801#discussion_r1410452499).

## Problem

The `pallet_balances` integrity test should correctly detect that the
runtime has correct distinct `HoldReasons` variant count. I assume the
same situation exists for RuntimeFreezeReason.

It is not a critical problem, if we set `MaxHolds` with a sufficiently
large value, everything should be ok. However, in this case, the
integrity_test check becomes less useful.

**Situation for "any" runtime:**
- `HoldReason` enums from different pallets:
```rust
        /// from pallet_nis
        #[pallet::composite_enum]
	pub enum HoldReason {
		NftReceipt,
	}

        /// from pallet_preimage
        #[pallet::composite_enum]
	pub enum HoldReason {
		Preimage,
	}

        // from pallet_state-trie-migration
        #[pallet::composit...

## Target Syntax
Adapted from
https://github.com/paritytech/polkadot-sdk/issues/206#issue-1865172283

```rust
// NOTE: this enum is optional and is auto-generated by the other macros if not present
#[pallet::task]
pub enum Task<T: Config> {
    AddNumberIntoTotal {
        i: u32,
    }
}

/// Some running total.
#[pallet::storage]
pub(super) type Total<T: Config<I>, I: 'static = ()> =
StorageValue<_, (u32, u32), ValueQuery>;

/// Numbers to be added into the total.
#[pallet::storage]
pub(super) type Numbers<T: Config<I>, I: 'static = ()> =
StorageMap<_, Twox64Concat, u32, u32, OptionQuery>;

#[pallet::tasks_experimental]
impl<T: Config<I>, I: 'static> Pallet<T, I> {
	/// Add a pair of numbers into the totals and remove them.
	#[pallet::task_list(Numbers::<T, I>::iter_keys())]
	#[pallet::task_condition(|i| Numbers::<T, I>::contains_key(i))]
	#[pallet::task_index(0)]
	pub fn add_number_into_total(i: u32) -> DispatchResult {
		let v = Numbers::<T, I>::take(i).ok_or(Error::<T, I>::NotFound)?;
		Total::<T, I>::mutate(|(total_keys, total_values)| {
			*total_keys += i;
			*total_values += v;
		});
		Ok(())
	}
}
```

      Add simple collator election mechanism (#1340) · 7d735fc8
      georgepisaltu authored 
      
Fixes https://github.com/paritytech/polkadot-sdk/issues/106

Port of cumulus PR https://github.com/paritytech/cumulus/pull/2960

This PR adds the ability to bid for collator slots even after the max
number of collators have already registered. This eliminates the first
come, first served mechanism that was in place before.

Key changes:
- added `update_bond` extrinsic to allow registered candidates to adjust
their bonds in order to dynamically control their bids
- added `take_candidate_slot` extrinsic to try to replace an already
existing candidate by bidding more than them
- candidates are now kept in a sorted list in the pallet storage, where
the top `DesiredCandidates` out of `MaxCandidates` candidates in the
list will be selected by the session pallet as collators
- if the candidacy bond is increased through a `set_candidacy_bond`
call, candidates which don't meet the new bond requirements are kicked

      `xcm`: Change `TypeInfo::path` to not include `staging` (#1948) · f3bf5c1a
      Bastian Köcher authored 
      
The `xcm` crate was renamed to `staging-xcm` to be able to publish it to
crates.io as someone as squatted `xcm`. The problem with this rename is
that the `TypeInfo` includes the crate name which ultimately lands in
the metadata. The metadata is consumed by downstream users like
`polkadot-js` or people building on top of `polkadot-js`. These people
are using the entire `path` to find the type in the type registry. Thus,
their code would break as the type path would now be [`staging_xcm`,
`VersionedXcm`] instead of [`xcm`, `VersionedXcm`]. This pull request
fixes this by renaming the path segment `staging_xcm` to `xcm`.

This requires: https://github.com/paritytech/scale-info/pull/197
