The GenesisConfig is currently one of the only things for that we still require the native runtime. It isn't compiled for wasm right now. We also require the native runtime to load a GenesisConfig from a JSON file and as the GenesisConfig can change with newer native runtimes we got the raw chain spec that only contains the key/value storage pairs of the genesis block. When we remove the native runtime we need a new way to handle the GenesisConfig.

I propose that we put the GenesisConfig into the genesis wasm. This means that we start compiling the GenesisConfig for wasm, but I would put this behind some rust feature. So, the normal production builds should not include the GenesisConfig anymore. This is done to reduce the size of the wasm binary. I would also keep supporting the serialization of the GenesisConfig into JSON. If the GenesisConfig is part of the genesis wasm, we have some nice advantages. The first one being that we could keep the JSON serialized GenesisConfig in the chain spec and even distribute this chain spec as we would call into the genesis wasm to parse and generate the genesis block. This would require that we move out the genesis wasm from the actual genesis field in the chain spec to some dedicated field from where we can load the wasm binary. Another advantage would be that we could finally make the chain-spec-builder work properly. Currently this binary isn't really working for chain specs that aren't build from the kitchensink-runtime. The chain-spec-builder could be passed some crate name that belongs to some runtime and then it would generate the chain spec for this runtime. We could also enable certain features in the runtime etc.

To build what I outlined above, we would need the following:

  • Make GensisConfig build in wasm. This will require supporting serde in the wasm build to serialize/deserialize the GenesisConfig to/from JSON.
  • Add a new runtime api GenesisBuilder (better name should be found) that can be used to build the genesis config, load it etc.
  • Change the chain spec to have a dedicated field for the code.
  • Conditionally compile GenesisConfig into the wasm binary. By default the GenesisConfig should probably be compiled into the wasm binary. When doing a on-chain build there should exist a feature to disable the GenesisConfig.

Is anyone really using runtime-formatted JSON specs? All we really need is raw spec which does not require serde.

I think zombienet relies on meddling with the JSON chain spec and other testing tools probably as well.
Also it is very convenient for debugging…

Yeah and this will open a lot of possibilities. We will be able to ship json chain specs without them breaking, as the wasm file that loads them stays the same. We will be able to write tools that can modify chain specs very easily etc. It improves the user experience quite a lot.

I see it is a nice to have but not essential. We can always load metadata from wasm and use it to convert between the raw values and JSON. polkadot.js makes this relatively easy.

If this feature doesn't need to be part of Substrate, maybe it doesn't need to be part of Substrate?

Good point, if that works good enough we don't need serde/json support.

Chopsticks already implemented this feature and it works well.

Custom storage override:
https://github.com/AcalaNetwork/chopsticks/blob/master/configs/kusama.yml

Code that convert yaml/json to hex:

Yeah to hex is easy, the other way around is more the problem. GenesisConfig fields are also not directly the storage items and can be from a different layout and then use custom logic to fill the storage. All in all still something that sounds useful to me. Especially as it is really just much easier for people to interact with it.

We would also then "disable" the GenesisConfig for builds that are going on chain as runtime upgrade to remove serde etc. So, there isn't really any downside.

* [ci] Enable zombienet jobs in PRs (#2361)

Since preparation for the merge queues needs more time I'm enabling
zombienet jobs in PRs CI back.

* westend: remove SessionKeys migration already applied on-chain (#2363)

Westend now successfully updated to `spec: 103000`, we **have to
remove** the session keys migration before the next release as it
doesn't gracefully handle reapplying it.

* Fix Typo: `PalletXcmExtrinsicsBenchmark` (#2354)

Missed in https://github.com/paritytech/polkadot-sdk/pull/1672

* add pallet nomination-pools versioned migration to kitchensink (#2167)

The versioned migrations are already there in pallet nomination-pools:

Just updating the kitchensink runtime to point to them.

This is also nice because it points the dev to an example of how to use
`VersionedMigration`.

* [NPoS] Check if staker is exposed in paged exposure storage entries (#2369)

Addresses a bug caused by
https://github.com/paritytech/polkadot-sdk/pull/1189. The changes are
still not released yet, so would like to push the fix soon so it can go
together with the release of the above PR.

`fast_unstake` checks if a staker is exposed in an era. However, this fn
is still returning whether the staker is exposed based on the old
storage item. This PR fixes that by looking in both old and new exposure
storages.

Also adds some integrity tests for paged exposures.

* Beefy: small fixes (#2378)

Related to #2285

- save the state of the BEEFY gadget after processing a finality proof.
We need this in order to avoid skipping blocks.
- avoid reprocessing the old state when not necessary

* crypto: `lazy_static` removed, light parser for address URI added (#2250)

The `lazy_static` package does not work well in `no-std`: it requires
`spin_no_std` feature, which also will propagate into `std` if enabled.
This is not what we want.

This PR provides simple address uri parser which allows to get rid of
_regex_ which was used to parse the address uri, what in turns allows to
remove lazy_static.

Three regular expressions
(`SS58_REGEX`,`SECRET_PHRASE_REGEX`,`JUNCTION_REGEX`) were replaced with
the parser which unifies all of them.

The new parser does not support Unicode, it is ASCII only.

# Description

Sometimes changing file descriptor limits is not allowed, but there is
no need to crash the node if/when this happens. Since `fdlimit`'s author
decided to use panics instead of returning `Result`, we need to catch
it.

* Relax `force_default_xcm_version` for testnet system parachains (#2385)

This PR fixes two things:
- relax `force_default_xcm_version` for testnet system parachains (e.g.
BridgeHubWestend has now 2 and there is no way to change it to 3, so we
need to call `force_xcm_version(3)` for every parachain that it is
connected to, because we send XCMv3 messages)
- add `Storage` item to `PolkadotXcm` pallet definition (now we cannot
see storage items for `pallet_xcm` in PJS)


## TODO

- [ ] when merged open PR to `polkadot-fellows/runtimes` repo

* Make collator RPC mode non-experimental (#2381)

The `--relay-chain-rpc-urls` CLI flag has been available for a while
now. We have collators with this running and parachain teams are also
using it. It should be fine now to remove the experimental status.

* Fix migrations and add CI check for new system chains (#2336)

Westend Collectives migration CI check can be fixed once we have
https://github.com/paritytech/try-runtime-cli/pull/58, will open another
PR once it is available.

* remove retry from backers on failed candidate validation (#2182)

Hey guys, as discussed I've changed the name to a more general one
`PvfExecKind`, is this good or too general?
Creating this as a draft, I still have to fix the tests.

* PVF worker: switch on seccomp networking restrictions (#2221)

* cumulus-consensus-common: block import: `delayed_best_block` flag added (#2001)

This PR adds the `delayed_best_block` flag to `ParachainBlockImport`. If
not set, the `params.fork_choice` is not updated (to
`ForkChoiceStrategy::Custom`) during the block import.

When `delayed_best_block` is set to `false` all parachain blocks on the
[longest
fork](https://github.com/paritytech/polkadot-sdk/blob/552be4800d9e4b480f79a300fc531783e04be099/substrate/client/service/src/client/client.rs#L708-L709)
will be notified as the best block, allowing transaction pool to be
updated with every imported block.

Otherwise imported blocks will not be notified as best blocks
(`fork_choice=ForkChoiceStrategy::Custom(false)`), and transaction pool
would be updated only with best block received from relay-chain.

Improvement for: #1202

* Different XCM builders, default one requires fee payment (#2253)

Adding on top of the new builder pattern for creating XCM programs, I'm
adding some more APIs:

```rust
let paying_fees: Xcm<()> = Xcm::builder() // Only allow paying for fees
  .withdraw_asset() // First instruction has to load the holding register
  .buy_execution() // Second instruction has to be `buy_execution`
  .build();

let paying_fees_invalid: Xcm<()> = Xcm::builder()
  .withdraw_asset()
  .build(); // Invalid, need to pay for fees

let not_paying_fees: Xcm<()> = Xcm::builder_unpaid()
  .unpaid_execution() // Needed
  .withdraw_asset()
  .deposit_asset()
  .build();

let all_goes: Xcm<()> = Xcm::builder_unsafe() // You can do anything
  .withdraw_asset()
  .deposit_asset()
  .build();
```

The invalid bits are because the methods don't even exist on the types
that you'd want to call them on.

* Disable any peer connections for parachain nodes in pov-recovery zombienet test (#2475)

I noticed that this test broke at some point. The parachain nodes should

In this test I now take additional measures so we check that each nodes
really uses pov-recovery to get the blocks.

* [NPoS] Use EraInfo to manipulate exposure in fast-unstake tests (#2459)

The FastUnstake pallet tests were previously directly modifying storage
items in the pallet-staking to alter exposure. However, due to the
introduction of the [new paged exposure
feature](https://github.com/paritytech/polkadot-sdk/pull/1189) these
tests were not testing against correct storage items. This issue
resulted in a bug that I didn't catch, which has been addressed in [this
fix](https://github.com/paritytech/polkadot-sdk/pull/2369).

This PR introduces a modification to how the pallet-fast-unstake handles
exposure. It now utilizes `pallet-staking::EraInfo` to set or mutate
Exposures.

* Remove `RuntimeApi` dependency on system parachain runtime code (#2455)

The last issue blocking the removal of the Polkadot and Kusama system
parachains from the repo in #1737 is the dependency on the runtime code
through the RuntimeApi in `polkadot-parachain`.

This PR introduces two fake runtimes to satisfy the build requirements
and changes the `new_partial` function to make it not be generic over
the runtimes.
The reason for the second runtime is the different Aura keys used in
Polkadot Asset Hub, as the impl for AuraApi depends on this type.
If this changes the `RuntimeApi` generic could be removed completely
from all functions in `services.rs` and and generic type parameters in
`services.rs` and specified as a concrete type to TFullClient`.

* PVF: remove audit log access (#2461)

* New runtime `spec_version` format + backport of the bump to 1.4.0 (#2468)

## Overview

This PR aligns the `spec_version` formatting to the [recent
changes](https://github.com/polkadot-fellows/runtimes/pull/26/files#diff-efa4caeb17487ecb13d8f5eb7863c3241d84afa2e73fbf25909a2ca89df0f362R142)
made for the Polkadot/Kusama runtimes.

It also backports the latest version `v1.4.0` bumps as `1_004_000`.

## Details

During the switch from `v0.9` to `v1.x`, the format of the
`spec_version` was modified from: `(M)m_ppp` for a runtime considered on
version `M.m.pp`. For instance `0.9.42` had a `spec_version` of `9420`.

With the transition to `v1.x`, the format was changed to a bigger number
(still `u32`) formatted as `MM_mm_ppp` where `1.2.3` would be stored as
`01_02_003`.

This PR aligns the format with that has been introduced in the
fellowship repo: `MMM_mmm_ppp`.

* Zombienet tests - disputes on finalized blocks (#2184)

**Overview:**
Adding an extra malus variant focusing on disputing finalized blocks. It
will:
- wrap around approval-voting
- listen to `OverseerSignal::BlockFinalized` and when encountered start
a dispute for the `dispute_offset`th ancestor
- simply pass through all other messages and signals

Add zombienet tests testing various edgecases:
- disputing freshly finalized blocks
- disputing stale finalized blocks
- disputing eagerly pruned finalized blocks (might be separate PR)

**TODO:**
- [x] Register new malus variant
- [x] Simple pass through wrapper (approval-voting)
- [x] Simple network definition
- [x] Listen to block finalizations
- [x] Fetch ancestor hash
- [x] Fetch session index
- [x] Fetch candidate
- [x] Construct and send dispute message
- [x] zndsl test 1 checking that disputes on fresh finalizations resolve
valid Closes #1365
- [x] zndsl test 2 checking that disputes for too old finalized blocks
are not possible Closes #1364
- [ ] zndsl test 3 checking that disputes for candidates with eagerly
pruned relay parent state are handled correctly #1359 (deferred to a
separate PR)
- [x] Unit tests for new malus variant (testing cli etc)
- [x] Clean/streamline error handling

* Build the standard library crates when building the runtimes (#2217)

Our executor currently only supports the WASM MVP feature set, however
nowadays when compiling WASM the Rust compiler has more features enabled
by default.

We do set the `-C target-cpu=mvp` flag to make sure that *our* code gets
compiled in a way that is compatible with our executor, however this
doesn't affect Rust's standard library crates (`std`, `core` and
`alloc`) which are by default precompiled and still can make use of
these extra features.

So in this PR we force the compiler to also compile the standard library
crates for us to make sure that they also only use the MVP features.

I've added the `WASM_BUILD_STD` environment variable which can be used
to disable this behavior if set to `0`.

Unfortunately this *will* slow down the compile times when building
runtimes, but there isn't much that we can do about that.

This is not a breaking change per se - the call types do not change, but
is noteworthy as UIs will now want to pass the stash account into
`chill_other` calls, & metadata will reflect this.

Note: This is very low impact. `chill_other` has [hardly ever been
used](https://polkadot.subscan.io/extrinsic?address=&module=staking&call=chill_other&result=all&signedChecked=signed%20only&startDate=&endDate=&startBlock=&timeType=date&version=9431&endBlock=)
on Polkadot - notwithstanding the one called 11 days ago at block
18177457 that was a part of test I did, the last call was made 493 days
ago. Only 2 calls have ever been successful.

* CI: Fix `build-and-attach-release-runtimes.yml` (#2471)

Incorporate suggestion from release team to get this workflow working.

edit: worked on this test GH release:
https://github.com/paritytech/polkadot-sdk/releases/tag/liam-debug-ghw.
let's try it.

* Fixes cumulus README instructions (#2442)

README instructions fixes to be compatible with the `polkadot-prepare`
and `polkadot-execute` binary split.

* Pools: Add ability to configure commission claiming permissions (#2474)

Addresses #409.

This request has been raised by multiple community members - the ability
for the nomination pool root role to configure permissionless commission
claiming:

> Would it be possible to have a claim_commission_other extrinsic for
claiming commission of nomination pools permissionless?

This PR does not quite introduce this additional call, but amends
`do_claim_commission` to check a new `claim_permission` field in the
`Commission` struct, configured by an enum:

```
enum CommissionClaimPermission {
   Permissionless,
   Account(AccountId),
}
```
This can be optionally set in a bonded pool's
`commission.claim_permission` field:

```
struct BondedPool {
   commission: {
      <snip>
      claim_permission: Option<CommissionClaimPermission<T::AccountId>>,
   },
   <snip>
}
```

This is a new field and requires a migration to add it to existing
pools. This will be `None` on pool creation, falling back to the `root`
role having sole access to claim commission if it is not set; this is
the behaviour as it is today. Once set, the field _can_ be set to `None`
again.

#### Changes
- [x] Add `commision.claim_permission` field.
- [x] Add `can_claim_commission` and amend `do_claim_commission`.
- [x] Add `set_commission_claim_permission` call.
- [x] Test to cover new configs and call.
- [x] Add and amend benchmarks.
- [x] Generate new weights + slot into call
`set_commission_claim_permission`.
- [x] Add migration to introduce `commission.claim_permission`, bump
storage version.
- [x] Update Westend weights.
- [x] Migration working.

* Added NetworkId::PolkadotBulletin variant (#2517)

We're going to bridge Polkadot Bridge Hub with [Polkadot Bulletin
chain](https://github.com/zdave-parity/polkadot-bulletin-chain) soon
(and Rococo Bridge Hub with 1:1 copy of Polkadot Bulletin chain even
sooner), so we need a variant for that chain in `NetworkId`. As
suggested, I'm adding a new variant for it to the `NetworkId` (we may
have used `ByGenesis(_)`, but decision was made to have a dedicated
variant for that).

* polkadot: disable block authoring backoff on production networks (#2510)

Currently the polkadot node will backoff from block authoring if
finality starts lagging. This PR disables this mechanism on production
networks (polkadot and kusama) and adds a flags to optionally force
enabling it.

* Set `frame_system::LastRuntimeUpgrade` after running `try-runtime` migrations (#2515)

Sets `frame_system::LastRuntimeUpgrade` after running try-runtime
migrations to better emulate real behavior.

This fixes an issue where migrations using the spec version to determine
whether to execute can incorrectly fail idempotency checks.

@s0me0ne-unkn0wn noticed this issue with the session key migration
introduced in https://github.com/paritytech/polkadot-sdk/pull/2265.

This PR adds `derive_impl` on all `frame_system` config impls for mock
runtimes. The overridden configs are maintained as of now to ensure
minimal changes.

* polkadot: remove grandpa pause support (#2511)

This was never used and we probably don't need it anyway.

* Remove pov-recovery race condition/Improve zombienet test (#2526)

The test was a bit flaky on CI. 

There was a race condition in the pov-recovery system. If the timing is
bad, it can happen that a block waits for a parent that is already
queued for import. The check if a block has children waiting happens
when we insert into the import queue. So we need to do an additional
check once we receive the import notification for the parent block.

Second issue is that `alice` was missing `--in-peers 0` and `--out-peers
0`, so alice was sometimes still fetching block via sync and the
assertion on the logs in zombienet would fail.

There is another potential issue that I saw once locally. We have a
failing pov-recovery queue that fails from time to time to check that
the retry mechanism does what it should. We now make sure that the same
candidate is never failed twice, so the tests become more predictable.

* Rework the event system of `sc-network` (#1370)

This commit introduces a new concept called `NotificationService` which
allows Polkadot protocols to communicate with the underlying
notification protocol implementation directly, without routing events
through `NetworkWorker`. This implies that each protocol has its own
service which it uses to communicate with remote peers and that each
`NotificationService` is unique with respect to the underlying
notification protocol, meaning `NotificationService` for the transaction
protocol can only be used to send and receive transaction-related
notifications.

The `NotificationService` concept introduces two additional benefits:
  * allow protocols to start using custom handshakes
  * allow protocols to accept/reject inbound peers

Previously the validation of inbound connections was solely the
responsibility of `ProtocolController`. This caused issues with light
peers and `SyncingEngine` as `ProtocolController` would accept more
peers than `SyncingEngine` could accept which caused peers to have
differing views of their own states. `SyncingEngine` would reject excess
peers but these rejections were not properly communicated to those peers
causing them to assume that they were accepted.

With `NotificationService`, the local handshake is not sent to remote
peer if peer is rejected which allows it to detect that it was rejected.

This commit also deprecates the use of `NetworkEventStream` for all
notification-related events and going forward only DHT events are
provided through `NetworkEventStream`. If protocols wish to follow each
other's events, they must introduce additional abtractions, as is done
for GRANDPA and transactions protocols by following the syncing protocol
through `SyncEventStream`.

* Remove system parachains Polkadot and Kusama runtimes (#1737)

Since the Polkadot and Kusama runtimes are no longer in the repo, the
relevant systems parachains runtimes also need to be removed. More
context [here](https://github.com/paritytech/polkadot-sdk/issues/603)
and [here](https://github.com/paritytech/polkadot-sdk/pull/1731).

Removes the following:
- `asset-hub-kusama` and `asset-hub-polkadot`
- `bridge-hub-kusama` and `bridge-hub-polkadot`
- `collectives-polkadot`
- `glutton-kusama`

Partially solves #603 and adds to #1731.

* Improve `CodeExecutor` (#2358)

Since `sp-state-machine` and `GenesisConfigBuilderRuntimeCaller` always
set `use_native` to be false.
We should remove this param and make `NativeElseWasmExecutor` behave
like its name.
It could make the above components use the correct execution strategy.

Maybe polkadot do not need about `NativeElseWasmExecutor` anymore. But
it is still needed by other chains and it's useful for debugging.

* Adding LuckyFriday's Bootnodes per IBP Application (#2538)

Good day,

This PR requests the inclusion of two bootnode entries for Polkadot,
Kusama and Westend as part of LuckyFriday's IBP application. The nodes
are hosted on self-owned hardware in a co-located facility. We've
undertaken connectivity tests ourselves and also from members of the
IBP.

The test commands used are as follows:

```
polkadot --chain westend --base-path /tmp/node --name "Boot" --reserved-only --reserved-nodes "/dns/ibp-boot-westend.luckyfriday.io/tcp/30334/wss/p2p/12D3KooWDg1YEytdwFFNWroFj6gio4YFsMB3miSbHKgdpJteUMB9" --no-hardware-benchmarks

```

All tests yielded syncing with 1 peer, a positive result. We have also
backed up our node-key in the event that restoration is required.

I hope that the aforementioned meets the requirement for inclusion and
look forward to a speedy turnaround.

## Way Forward

First, a version of this is deployed temporarily
[here](https://blog.kianenigma.nl/polkadot-sdk/developer_hub/index.html).
I will keep it up to date on a daily basis.

### This Pull Request

I see two ways forward: 

1. We acknowledge that everything in `developer-hub` is going to be WIP,
and merge this asap. We should not yet use links to this crate anywhere.
2. We make this be the feature branch, make PRs against this, and either
gradually backport it, or only merge to master once it is done.

I am personally in favor of option 1. If we stick to option 2, we need a
better way to deploy a staging version of this to gh-pages.

### Issue Tracking

The main issues related to the future of `developer_hub` are:

@bkchr I need the native runtime for the GenesisBuilder because I'm using async rust + many other features behind std to instantiate my pallet since it's so complex.

Can you give an example on what exactly you are doing there? Especially as GenesisBuilder doesn't support async.

@JuaniRios
Copy link

@bkchr I'm using the current_thread runtime of Tokio to instantiate several tasks inside the GenesisBuilder.

This is because my pallet creates projects that go through several stages as time (measured in blocks) moves forward.

Now to test the UI, we need to start a local parachain with one project in each stage, and for this, every time I go forward in time, I need to see which project needs to resume execution.

  • Normal way we create projects in mock:
    Project A execution (@ State 1) ---move blocks--> Project A execution (state 2) ---move blocks--> Project A execution(state 3)

The previous example is run through a function, such that in testing if we want to create a project at state 3 and then do some tests, we call new_state_3_project().

Each state has a certain time it can remain alive. After that, it moves into either the success or failed state.

If we use the normal synchronous way of instantiating our test projects, then by the time we advance blocks to create a new project in another state, the previous instantiated project states become invalid.

The current way which is already working, is by creating an async project creation function, which blocks execution whenever it wants to advance blocks. Before blocking though, it notifies an orchestrator at which block it wants to be awakened at.

The orchestrator then starts advancing blocks until it reaches the lowest block required by one of the instantiating project functions and hands over execution to it.

A simple way for one test would be to hardcode each transition of each project instead of relying on calling functions and expecting them to hand over execution between themselves. But then I wouldn't be able to pass in any info at Genesis to start any number of projects at any state.

If this is too confusing, I can give you access to our repo at Polimec and you can look through the code yourself.
In any case just by spawning Tokio tasks inside GenesisBuilder, then we couldn't use the wasm runtime no?

I couldn't get the Genesis builder working using the multithreaded Tokio runtime since each task wasn't executing under the context of the substrate storage. But using the single-threaded runtime did the trick.

@bkchr We just open-sourced our code, here is where we are using async in the builder: https://github.com/Polimec/polimec-node/blob/da9d1ee0062ead7a62f815647813ada48e4c2250/pallets/funding/src/lib.rs#L1386

As mentioned before, we're using the single-threaded Tokio runtime and it works just fine.

@JuaniRios why don't you run this async code in the node and then pass the processed data into the runtime?

@JuaniRios
Copy link
Contributor

@bkchr the purpose of the async code is to create genesis storage to use in testing. Since this is the main use case of the genesis builder, I believe it makes sense to be inside the runtime code.

How would you see us achieving the same thing with the code moved to the node?

Also I heard there that soon we would move to an "omninode", so we would stop being able to put our own code into the substrate node, and just use a generic one imported as a crate

@michalkucharczyk

If this is only for testing - maybe you could use TestExternalities to build a genesis storage? You could call your build function from there.

Once you have a genesis storage it should be easy to convert it to runtime GensisConfig / chainspec.

JuaniRios commented Jan 25, 2024

@michalkucharczyk thanks for the reply!

So basically do what the genesis builder is already doing, but hardcoding the logic in the node instead of calling the code from the runtime?

What would be the advantage of this?

If polkadot-sdk removes the native runtime, then calling TestExternalities on the node will still make it impossible to use std no?
Or will TestExternalities always use std?

EDIT:
Is it bad to have code used for testing inside the runtime?
From what I've seen, the GenesisBuilder is mostly used in tests, since most parachains will launch with a minimal runtime and add pallets through runtime upgrades, which makes the genesis configs rather useless

Stupid question, could we use async to run multiple extrinsics simultaneously if they don't read/write from the same storage?
The async would let us run another extrinsic's code while the storage reads/writes of another are blocking.

Would something like this need to be programmed in the runtime itself, or could the node know each extrinsic which storage items it will touch and so know which other extrinsics it can batch concurrently?

There will probably be such a node, but no one forces you to use this. This is more to make it easier to create parachains. However, with the omninode you would not have the native runtime either and so your "hack" wouldn't work.

I honestly still don't get why you need to use async there and what the code is doing. I also don't want to dig into this. As I already told you, you can move this code somewhere else and then add whatever data this async code is generating to your GenesisConfig and then in the runtime put it into the genesis storage. Your you do what @michalkucharczyk proposed with the TestExternalities.

Stupid question, could we use async to run multiple extrinsics simultaneously if they don't read/write from the same storage?
The async would let us run another extrinsic's code while the storage reads/writes of another are blocking.

This is a complete different topic and we don't support this right now. I know that there exists some frameworks supporting "parallel" execution of transactions. However, it is questionable if you really need this right now.

If polkadot-sdk removes the native runtime, then calling TestExternalities on the node will still make it impossible to use std no? Or will TestExternalities always use std?

Removal of native runtime in node means that node is no longer coupled with runtime and is able to do all the work with just wasm runtime blob. No types or native calls to runtime are hard-coded in node. It also means that generic node has no deps on runtime crate. All node requires is a wasm blob.

But your runtime is still just a crate, which maybe used in whatever-you-want environment (e.g. wasm runtime or tests). You can write tools or tests (or even your flavor of node) that are using your runtime crate.

Hope this addresses your doubts.

Last question, will the "std" feature config be removed from the TestExternalities type as part of the native-runtime removal?

I don't think so, however I am not an authority in this area :)

I looked into code again, you perhaps don't even need to use TestExternatlities. Your RuntimeGenesisConfig implements sp_runtime::BuildStorage trait, so you can simply get the genesis storage by calling build_storage method. Start from here

@JuaniRios

I thought part of the move to native-runtime free was to remove "std" from the macro expansion of the GenesisBuilder struct of each pallet.
That is the main pain point which started the discussion, because if std is not passed into that struct by the macro, then I cannot use tokio.

This is how the current expansion looks:

    #[cfg(feature = "std")]
    impl<T: Config> frame_support::sp_runtime::BuildStorage for GenesisConfig<T> where
        T: Config + pallet_balances::Config<Balance=BalanceOf<T>>,
        <T as Config>::AllPalletsWithoutSystem:
        OnFinalize<BlockNumberFor<T>> + OnIdle<BlockNumberFor<T>> + OnInitialize<BlockNumberFor<T>>,
        <T as Config>::RuntimeEvent: From<Event<T>> + TryInto<Event<T>> + Parameter + Member,
        <T as pallet_balances::Config>::Balance: Into<BalanceOf<T>>,
    {
        fn assimilate_storage(&self, storage: &mut sp_runtime::Storage) -> std::result::Result<(), std::string::String> {
            frame_support::BasicExternalities::execute_with_storage(storage, || {
                self.build();
                Ok(())
            })
        }
    }

And also the RuntimeGenesisConfig generated by the construct_runtime! macro passes "std" to it, which will be removed after the native-runtime removal:

#[cfg(any(feature = "std", test))]
impl self::sp_api_hidden_includes_construct_runtime::hidden_include::sp_runtime::BuildStorage for RuntimeGenesisConfig {
    fn assimilate_storage(&self, storage: &mut self::sp_api_hidden_includes_construct_runtime::hidden_include::sp_runtime::Storage ) -> std::result::Result<(), String> {
        self::sp_api_hidden_includes_construct_runtime::hidden_include::BasicExternalities::execute_with_storage(storage, || {
            <Self as self::sp_api_hidden_includes_construct_runtime::hidden_include::traits::BuildGenesisConfig>::build(&self);
            Ok(())
        })
    }
}

The default node uses this struct with "std" enabled to build the genesis storage. So when std is removed, my code won't work anymore.

edited: Yeah, we need BuildGenesisConfig inside wasm blob, and there is special API (GenesisBuilder) so the node can call into wasm blob

That is the main pain point which started the discussion, because if std is not passed into that struct by the macro, then I cannot use tokio.

I don't see a problem here. Features are not passed by macro (which is just putting a #cfg guard into generated code), they are defined at compilation level (e.g. in Cargo.toml or via --features cargo flag).

I understand what you are saying, but if you remove the "std" cfg from theGenesisBuilder, it is also saying implicitly that you will now never call it with "std" by default.

I guess one solution would be like you suggested to have another genesis builder logic in my node, where I am calling it with "std" compiled.

If we generate the genesis storage by calling the code directly, does that mean that it will always be a "native runtime"?
It's not so clear to me what it means to run the runtime as wasm, since that was always abstracted away from me by the node.

I messed with naming so I edited my previous comment.

I guess one solution would be like you suggested to have another genesis builder logic in my node, where I am calling it with "std" compiled.

FWIS you already have this logic implemented. All you have to do is to call build_storage on the instance of your RuntimeGenesisConfig in std-enabled environment. This call will internally execute your build function (which uses async staff) and generate storage which should be converted into entries in raw genesis config.

If we generate the genesis storage by calling the code directly, does that mean that it will always be a "native runtime"?
It's not so clear to me what it means to run the runtime as wasm, since that was always abstracted away from me by the node.

If you need this only for testing, then I would not call it native runtime. You could think of it as some kind of util generating test chain-specs.

Think of native runtime as runtime code which is linked with node (thus name native), and is also a crate dependency for node which makes all internal (public) types and functions available in rust.

@michalkucharczyk Thank you for the answers, much more clear now!

Yes I am already calling build_storage on my RuntimeGenesisConfig by using the default node implementation, and running it with the command build-spec.

If I never move to the "omninode", does this mean that my "std" code will still run, even if the native-runtime is "removed"?

The runtime now can provide a number of predefined presets of
`RuntimeGenesisConfig` struct. This presets are intended to be used in
different deployments, e.g.: `local`, `staging`, etc, and should be
included into the corresponding chain-specs.

Having `GenesisConfig` presets in runtime allows to fully decouple node
from runtime types (the problem is described in #1984).

**Summary of changes:**
- The `GenesisBuilder` API was adjusted to enable this functionality
(and provide better naming - #150):
   ```rust

    fn build_state(value: serde_json::Value);
    pub struct PresetId(Vec<u8>);

`build_config` was renamed to `build_state`. As a consequence a node
won't be able to interact with genesis config for older runtimes. The
cleanup was made for sake of API simplicity. Also IMO maintaining
compatibility with old API is not so crucial.
