MBM `try-runtime` support (#4251) · cc6a5130

Liam Aharon authored 6 months ago


# MBM try-runtime support

This MR adds support to the try-runtime trait such that the
try-runtime-CLI will be able to support MBM testing
[here](https://github.com/paritytech/try-runtime-cli/pull/90). It mainly
adds two feature-gated hooks to the `SteppedMigration` hook to
facilitate testing. These hooks are named `pre_upgrade` and
`post_upgrade` and have the same signature and implications as for
single-block migrations.

## Integration

To make use of this in your Multi-Block-Migration, just implement the
two new hooks and test pre- and post-conditions in them:

```rust
#[cfg(feature = "try-runtime")]
fn pre_upgrade() -> Result<Vec<u8>, frame_support::sp_runtime::TryRuntimeError> {
	// ...
}

#[cfg(feature = "try-runtime")]
fn post_upgrade(prev: Vec<u8>) -> Result<(), frame_support::sp_runtime::TryRuntimeError> {
    // ...
}
```

You may return an error or panic in these functions to indicate failure.
This will then show up in the try-runtime-CLI and can be used in CI for
testing.

Changes:
- Adds `try-runtime` gated methods `pre_upgrade` and `post_upgrade` on
`SteppedMigration`
- Adds `try-runtime` gated methods `nth_pre_upgrade` and
`nth_post_upgrade` on `SteppedMigrations`
- Modifies `pallet_migrations` implementation to run pre_upgrade and
post_upgrade steps at the appropriate times, and panic in the event of
migration failure.

Bridges lane id agnostic for backwards compatibility (#5649) · 710e74dd

Branislav Kontur authored 6 months ago


This PR primarily fixes the issue with
`zombienet-bridges-0001-asset-transfer-works` (see:
https://gitlab.parity.io/parity/mirrors/polkadot-sdk/-/jobs/7404903).

The PR looks large, but most of the changes involve splitting `LaneId`
into `LegacyLaneId` and `HashedLaneId`. All pallets now use `LaneId` as
a generic parameter.

The actual bridging pallets are now backward compatible and work with
actual **substrate-relay v1.6.10**, which does not even known anything
about permissionless lanes or the new pallet changes.



## Important

- [x] added migration for `pallet_bridge_relayers` and
`RewardsAccountParams` change order of params, which generates different
accounts

## Deployment follow ups
- [ ] fix monitoring for
`at_{}_relay_{}_reward_for_msgs_from_{}_on_lane_{}`
- [ ] check sovereign reward accounts - because of changed
`RewardsAccountParams`
- [ ] deploy another messages instances for permissionless lanes - on
BHs or AHs?
- [ ] return back `open_and_close_bridge_works` for another
`pallet-bridge-messages` instance

elastic scaling: add core selector to cumulus (#5372) · b9eb68bc

Alin Dima authored 6 months ago

Partially implements
https://github.com/paritytech/polkadot-sdk/issues/5048

- adds a core selection runtime API to cumulus and a generic way of
configuring it for a parachain
- modifies the slot based collator to utilise the claim queue and the
generic core selection

What's left to be implemented (in a follow-up PR):
- add the UMP signal for core selection into the parachain-system pallet

cumulus/minimal-node: added prometheus metrics for the RPC client (#5572) · c8d5e5a3

Iulian Barbu authored 6 months ago


# Description

When we start a node with connections to external RPC servers (as a
minimal node), we lack metrics around how many individual calls we're
doing to the remote RPC servers and their duration. This PR adds metrics
that measure durations of each RPC call made by the minimal nodes, and
implicitly how many calls there are.

Closes #5409 
Closes #5689

## Integration

Node operators should be able to track minimal node metrics and decide
appropriate actions according to how the metrics are interpreted/felt.
The added metrics can be observed by curl'ing the prometheus metrics
endpoint for the ~relaychain~ parachain (it was changed based on the
review). The metrics are represented by
~`polkadot_parachain_relay_chain_rpc_interface`~
`relay_chain_rpc_interface` namespace (I realized lining up
`parachain_relay_chain` in the same metric might be confusing :).
Excerpt from the curl:

```
relay_chain_rpc_interface_bucket{method="chain_getBlockHash",chain="rococo_local_testnet",le="0.001"} 15
relay_chain_rpc_interface_bucket{method="chain_getBlockHash",chain="rococo_local_testnet",le="0.004"} 23
relay_chain_rpc_interface_bucket{method="chain_getBlockHash",chain="rococo_local_testnet",le="0.016"} 23
relay_chain_rpc_interface_bucket{method="chain_getBlockHash",chain="rococo_local_testnet",le="0.064"} 23
relay_chain_rpc_interface_bucket{method="chain_getBlockHash",chain="rococo_local_testnet",le="0.256"} 24
relay_chain_rpc_interface_bucket{method="chain_getBlockHash",chain="rococo_local_testnet",le="1.024"} 24
relay_chain_rpc_interface_bucket{method="chain_getBlockHash",chain="rococo_local_testnet",le="4.096"} 24
relay_chain_rpc_interface_bucket{method="chain_getBlockHash",chain="rococo_local_testnet",le="16.384"} 24
relay_chain_rpc_interface_bucket{method="chain_getBlockHash",chain="rococo_local_testnet",le="65.536"} 24
relay_chain_rpc_interface_bucket{method="chain_getBlockHash",chain="rococo_local_testnet",le="+Inf"} 24
relay_chain_rpc_interface_sum{method="chain_getBlockHash",chain="rococo_local_testnet"} 0.11719075
relay_chain_rpc_interface_count{method="chain_getBlockHash",chain="rococo_local_testnet"} 24
```

## Review Notes

The way we measure durations/hits is based on `HistogramVec` struct
which allows us to collect timings for each RPC client method called
from the minimal node., It can be extended to measure the RPCs against
other dimensions too (status codes, response sizes, etc). The timing
measuring is done at the level of the `relay-chain-rpc-interface`, in
the `RelayChainRpcClient` struct's method 'request_tracing'. A single
entry point for all RPC requests done through the
relay-chain-rpc-interface. The requests durations will fall under
exponential buckets described by start `0.001`, factor `4` and count
`9`.

[xcm-emulator] Better logs for message execution and processing (#5712) · b230b0e3

Francisco Aguirre authored 6 months ago

When running XCM emulated tests and seeing the logs with `RUST_LOG=xcm`
or `RUST_LOG=xcm=trace`, it's sometimes a bit hard to figure out the
chain where the logs are coming from.

I added a log whenever `execute_with` is called, to know the chain which
makes the following logs. Looks like so:

<img width="1499" alt="Screenshot 2024-09-13 at 20 14 13"
src="https://github.com/user-attachments/assets/a31d7aa4-11d1-4d3e-9a65-86f38347c880">

There are already log targets for when UMP, DMP and HRMP messages are
being processed. To see them, you have to use the log targets `ump`,
`dmp`, and `hrmp` respectively. So `RUST_LOG=xcm,ump,dmp,hrmp` would let
you see every log.
I prefixed the targets with `xcm::` so you can get all the relevant logs
just by filtering by `xcm`. You can always use the whole target to see
just the messages being processed.

These logs showed the message as an array of bytes, I made them show a
hexadecimal string instead since that's easier to copy in case you want
to decode it or use it in another tool. They look like this now:

<img width="1499" alt="Screenshot 2024-09-13 at 20 17 15"
src="https://github.com/user-attachments/assets/5abf4a97-1ea7-4832-b3b0-d54c54905d1a">

The HRMP and UMP ones are very similar.

revive: Limit the amount of static memory a contract can use (#5726) · 310ef5ce

Alexander Theißen authored 6 months ago


This will make sure that when uploading new code that the declared
static memory fits within a defined limit. We apply different limits to
code and data. Reason is that code will consume much more memory per
byte once decoded during lazy execution.

This PR:

1) Remove the MaxCodeLen from the `Config` to we maintain tight control
over it.
2) Defines a single `STATIC_MEMORY_BYTES` knob that limits the maximum
decoded size.
3) Enforces them only on upload but not on execution so we can raise
them later.
4) Adapt the worst case calculation in `integrity_check`.
5) Bumps the max stack depth from 5 to 10 as this will still fit within
our memory envelope.
6) The memory limit per contract is now a cool 1MB that can be spent on
data or code.
7) Bump PolkaVM for good measure
8) The blob is limited to 256kb which is just a sanity check to not even
try parsing very big inputs.

Transfer Polkadot-native assets to Ethereum (#5546) · fb7300ce

Ron authored 6 months ago

# Description

Adding support for send polkadot native assets(PNA) to Ethereum network
through snowbridge. Asset with location in view of AH Including:

- Relay token `(1,Here)`
- Native asset `(0,[PalletInstance(instance),GenereIndex(index)])`
managed by Assets Pallet
- Native asset of Parachain `(1,[Parachain(paraId)])` managed by Foreign
Assets Pallet

The original PR in https://github.com/Snowfork/polkadot-sdk/pull/128
which has been internally reviewed by Snowbridge team.

# Notes

- This feature depends on the companion solidity change in
https://github.com/Snowfork/snowbridge/pull/1155. Currently register PNA
is only allowed from
[sudo](https://github.com/Snowfork/polkadot-sdk/blob/46cb3528

/bridges/snowbridge/pallets/system/src/lib.rs#L621),
so it's actually not enabled. Will require another runtime upgrade to
make the call permissionless together with upgrading the Gateway
contract.

- To make things easy multi-hop transfer(i.e. sending PNA from Ethereum
through AH to Destination chain) is not support ed in this PR. For this
case user can switch to 2-phases transfer instead.

Closes #5453.

Proxies can now be used on `coretime-rococo`, `coretime-westend`,
`people-rococo` and `people-westend` in the same way as they can be on

litep2p: Update network backend to v0.7.0 (#5609) · 12eeb5df

Alexandru Vasile authored 6 months ago

This release introduces several new features, improvements, and fixes to
the litep2p library. Key updates include enhanced error handling,
configurable connection limits, and a new API for managing public
addresses.

For a detailed set of changes, see [litep2p
changelog](https://github.com/paritytech/litep2p/blob/master/CHANGELOG.md#070---2024-09-05).

This PR makes use of:
- connection limits to optimize network throughput
- better errors that are propagated to substrate metrics 
- public addresses API to report healthy addresses to the Identify
protocol

### Warp sync time improvement

Measuring warp sync time is a bit inaccurate since the network is not
deterministic and we might end up using faster peers (peers with more
resources to handle our requests). However, I did not see warp sync
times of 16 minutes, instead, they are roughly stabilized between 8 and
10 minutes.

For measuring warp-sync time, I've used

Update `RuntimeVerison` type and use `system_version` to derive extrinsics root `StateVersion` instead of `V0` (#4257)

This PR 
- Renames `RuntimeVersion::state_version` to `system_version`
- Uses `Runtime::system_version` to derive extrinsics root
`StateVersion` instead of default `StateVersion::V0`

This PR should not be breaking any existing chains so long as they use
same `RuntimeVersion::state_version` for `Runtime::system_version`

Using `RuntimeVersion::system_version = 2` will make the extrinsics root
to use `StateVersion::V1` instead of `V0`

Create a Basic Proving Trie for the Runtime (#3881) · 1cff666b

Shawn Tabrizi authored 6 months ago


This PR will introduce a `BasicProvingTrie` type, which makes it easy to
construct and prove data in a base-16 merkle trie within the runtime.

Data into the merkle trie only require that they implement `Encode` /
`Decode`.

A FRAME compatible `TrieError` was created and added to `DispatchError`.

Expected usage is to construct the merkle trie with all data offline,
and then place only the merkle root of that trie on-chain.

Also offchain, a user is given a compact merkle proof of some data they
want to prove exists on the blockchain.

Then in the runtime, you can call `verify_single_value_proof` or
`verify_proof` with the root, proof, and the keys and values you want to
verify exists in the merkle trie.

Closes https://github.com/paritytech/polkadot-sdk/issues/3880

Collective: dynamic deposit based on number of proposals (#3151) · cc3b7bbd

Muharem Ismailov authored 6 months ago


Introduce a dynamic proposal deposit mechanism influenced by the total
number of active proposals, with the option to set the deposit to none.

The potential cost (e.g., balance hold) for proposal submission and
storage is determined by the implementation of the `Consideration`
trait. The footprint is defined as `proposal_count`, representing the
total number of active proposals in the system, excluding the one
currently being proposed. This cost may vary based on the proposal
count. The pallet also offers various types to define a cost strategy
based on the number of proposals.

Two new calls are introduced:
- kill(origin, proposal_hash): the cancellation of a proposal,
accompanied by the burning of the associated cost/consideration ticket.
- release_proposal_cost(origin, proposal_hash): the release of the cost
for a non-active proposal.

Additionally change: 
- benchmarks have been upgraded to benchmarks::v2 for collective pallet;
- `ensure_successful` function added to the `Consideration` under
`runtime-benchmarks` feature.

Add parachain related parameters to `chain-spec-builder` (#4889) · 89b41c57

bader y authored 6 months ago


When using with `polkadot-parachain`, you usually need to specify the
`relay_chain` and `para_id` fields in the chain spec.

With this PR it can be achieved by specifying newly added `--para-id`
and `--relay-chain` command line args, e.g:
```
chain-spec-builder create -r _runtime.wasm  --para-id 100 --relay-chain xxx default
```

This was implemented by simple _json_ blobs merging.

Additionally unit tests covering basic functionality were added.

Also adds a fix for not overwriting the chain spec with the default
config each time, swallowing not standard fields is also fixed.

Fixes: #4873

cumulus/client: added external rpc connection retry logic (#5515) · 4d2f7932

Iulian Barbu authored 6 months ago

# Description

Adds retry logic that makes the RPC relay chain interface more reliable
for the cases of a collator connecting to external RPC servers.

Closes #5514
Closes #4278

Final solution still debated on #5514 , what this PR addresses might
change (e.g. #4278 might require a more advanced approach).

## Integration

Users that start collators should barely observe differences based on
this logic, since the retry logic applies only in case the collators
fail to connect to the RPC servers. In practice I assume the RPC servers
are already live before starting collators, and the issue isn't visible.

## Review Notes

The added retry logic is for retrying the connection to the RPC servers
(which can be multiple). It is at the level of the
cumulus/client/relay-chain-rpc-interface module, but more specifically
relevant to the RPC clients logic (`ClientManager`). The retry logic is
not configurable, it tries to connect to the RPC client for 5 times,
with an exponential backoff in between each iteration starting with 1
second wait time and ending with 16 seconds. The same logic is applied
in case an existing connection to an RPC is dropped. There is a
`ReconnectingWebsocketWorker` who ensures there is connectivity to at
least on RPC node, and the retry logic makes this stronger by insisting
on trying connections to the RPC servers list for 5 times.

## Testing

- This was tested manually by starting zombienet natively based on
[006-rpc_collator_builds_blocks.toml](https://github.com/paritytech/polkadot-sdk/blob/master/cumulus/zombienet/tests/0006-rpc_collator_builds_blocks.toml)
and observing collators don't fail anymore:

```bash
zombienet -l text --dir zbn-run -f --provider native spawn polkadot-sdk/cumulus/zombienet/tests/0006-rpc_collator_builds_blocks.toml
```

- Added a unit test that exercises the retry logic for a client
connection to a server that comes online in 10 seconds. The retry logic
can wait for as long as 30 seconds, but thought that it is too much for
a unit test. Just being conscious of CI time if it runs this test, but I
am happy to see suggestions around it too. I am not that sure either it
runs in CI, haven't figured it out entirely yet. The test can be
considered an integration test too, but it exercises crate internal
implementation, not the public API.

Collators example logs after the change:

Elastic scaling: introduce new candidate receipt primitive (#5322) · ad2ac0db

Andrei Sandu authored 6 months ago


closes https://github.com/paritytech/polkadot-sdk/issues/5044

This PR switches the runtime to the new receipts format (vstaging
primitives). I've implemented `From` to convert from new primitives to
`v7` primitives and used them in the node runtime api client
implementation. Until we implement the support in the node, it will
continue e to use the v7 primitives but the runtime apis already use the
new primitives.


An expected downside of RFC103 is decoding V2 receipts shows garbage
values if the input is V1:

[bridges-v2] Permissionless lanes (#4949) · 22100999

Branislav Kontur authored 6 months ago

Relates to:
https://github.com/paritytech/parity-bridges-common/issues/2451
Closes: https://github.com/paritytech/parity-bridges-common/issues/2500

## Summary

Now, the bridging pallet supports only static lanes, which means lanes
that are hard-coded in the runtime files. This PR fixes that and adds
support for dynamic, also known as permissionless, lanes. This means
that allowed origins (relay chain, sibling parachains) can open and
close bridges (through BridgeHubs) with another bridged (substrate-like)
consensus using just `xcm::Transact` and `OriginKind::Xcm`.

_This PR is based on the migrated code from the Bridges V2
[branch](https://github.com/paritytech/polkadot-sdk/pull/4427) from the
old `parity-bridges-common`
[repo](https://github.com/paritytech/parity-bridges-common/tree/bridges-v2)._

## Explanation

Please read
[bridges/modules/xcm-bridge-hub/src/lib.rs](https://github.com/paritytech/polkadot-sdk/blob/149b0ac2

/bridges/modules/xcm-bridge-hub/src/lib.rs#L17-L136)
to understand how managing bridges works. The basic concepts around
`BridgeId` and `LaneId` are also explained there.


## TODO

- [x] search and fix for comment: `// TODO:(bridges-v2) - most of that
stuff was introduced with free header execution:
https://github.com/paritytech/polkadot-sdk/pull/4102` - more info in the
comment
[bellow](https://github.com/paritytech/polkadot-sdk/pull/4427#issuecomment-2126625043)
- [x] TODO: there's only one impl of `EnsureOrigin<Success = Location>`

## TODO - not blocking review

**benchmarking:**
- [x] regenerate all relevant weights for BH/AH runtimes
- [ ] regenerate default weights for bridging pallets e.g.
`modules/messages/src/weights.rs`
- [ ] add benchmarks for `xcm-bridge-hub` pallet
https://github.com/paritytech/polkadot-sdk/issues/5550

**testing:**
- [ ] add xcm-emulator tests for Rococo/Penpal to Westend/Penpal with
full opening channel and sending/receiving `xcm::Transact`

**migrations:**
- [x] add migrations for BridgeHubRococo/Westend
https://github.com/paritytech/parity-bridges-common/issues/2794 (to be
reusable for P/K bridge)
  - [x] check also storage migration, if needed for pallets
  - [ ] migration for XCM type (optional)
  - [x] migration for static lanes to the dynamic (reuse for fellows)

**investigation:**
- [ ] revisit
https://github.com/paritytech/parity-bridges-common/issues/2380
- [ ] check congestion around `LocalXcmChannelManager` and
`OutboundLanesCongestedSignals` impls -
https://github.com/paritytech/polkadot-sdk/issues/5551
  - to be reusable for polkadot-fellows
- return `report_bridge_status` was remove, so we need to `XcmpQueue`
alternative?

collator-protocol: Handle unknown validator heads (#5538) · f58e2b80

Bastian Köcher authored 6 months ago

There is a race condition when a validator sends its heads to the
collator, but the collator doesn't yet know these heads. Before it is
aware of these heads by importing the block(s), any collation registered
on the collator is not announced to the validators. The collations
aren't advertised, because the collator doesn't know yet that these
heads of the validator are descendants of the collations relay parent.

The solution is to store these unknown heads of the validators and to
handle them when the collator updates its own view.

Swaps for XCM delivery fees (#5131) · 5291412e

Francisco Aguirre authored 6 months ago

# Context

Fees can already be paid in other assets locally thanks to the Trader
implementations we have.
This doesn't work when sending messages because delivery fees go through
a different mechanism altogether.
The idea is to fix this leveraging the `AssetExchanger` config item
that's able to turn the asset the user wants to pay fees in into the
asset the router expects for delivery fees.

# Main addition

An adapter was needed to use `pallet-asset-conversion` for exchanging
assets in XCM.
This was created in
https://github.com/paritytech/polkadot-sdk/pull/5130.

The XCM executor was modified to use `AssetExchanger` (when available)
to swap assets to pay for delivery fees.

## Limitations

We can only pay for delivery fees in different assets in intermediate
hops. We can't pay in different assets locally. The first hop will
always need the native token of the chain (or whatever is specified in
the `XcmRouter`).
This is a byproduct of using the `BuyExecution` instruction to know
which asset should be used for delivery fee payment.
Since this instruction is not present when executing an XCM locally, we
are left with this limitation.
To illustrate this limitation, I'll show two scenarios. All chains
involved have pools.

### Scenario 1

Parachain A --> Parachain B

Here, parachain A can use any asset in a pool with its native asset to
pay for local execution fees.
However, as of now we can't use those for local delivery fees.
This means transfers from A to B need some amount of A's native token to
pay for delivery fees.

### Scenario 2

Parachain A --> Parachain C --> Parachain B

Here, Parachain C's remote delivery fees can be paid with any asset in a
pool with its native asset.
This allows a reserve asset transfer between A and B with C as the
reserve to only need A's native token at the starting hop.
After that, it could all be pool assets.

## Future work

The fact that delivery fees go through a totally different mechanism
results in a lot of bugs and pain points.
Unfortunately, this is not so easy to solve in a backwards compatible
manner.
Delivery fees will be integrated into the language in future XCM
versions, following
https://github.com/polkadot-fellows/xcm-format/pull/53.

[3 / 5] Move crypto checks in the approval-distribution (#4928) · 6b854acc

Alexandru Gheorghe authored 6 months ago

# Prerequisite
This is part of the work to further optimize the approval subsystems, if
you want to understand the full context start with reading
https://github.com/paritytech/polkadot-sdk/pull/4849#issue-2364261568,

# Description
This PR contain changes, so that the crypto checks are performed by the
approval-distribution subsystem instead of the approval-voting one. The
benefit for these, is twofold:
1. Approval-distribution won't have to wait every single time for the
approval-voting to finish its job, so the work gets to be pipelined
between approval-distribution and approval-voting.

2. By running in parallel multiple instances of approval-distribution as
described here
https://github.com/paritytech/polkadot-sdk/pull/4849#issue-2364261568,
this significant body of work gets to run in parallel.

## Changes:
1. When approval-voting send `ApprovalDistributionMessage::NewBlocks` it
needs to pass the core_index and candidate_hash of the candidates.
2. ApprovalDistribution needs to use `RuntimeInfo` to be able to fetch
the SessionInfo from the runtime.
3. Move `approval-voting` logic that checks VRF assignment into
`approval-distribution`
4. Move `approval-voting` logic that checks vote is correctly signed
into `approval-distribution`
5. Plumb `approval-distribution` and `approval-voting` tests to support
the new logic.

## Benefits
Even without parallelisation the gains are significant, for example on
my machine if we run approval subsystem bench for 500 validators and 100
cores and trigger all 89 tranches of assignments and approvals, the
system won't fall behind anymore because of late processing of messages.
```
Before change
Chain selection approved after 11500 ms hash=0x0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a

After change

Chain selection approved after 5500 ms hash=0x0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a0a
```

## TODO:
- [x] Run on versi.
- [x] Update parachain host documentation.
