Substrate Client (/client/* / sc-*) is licensed under GPL v3.0 with a classpath linking exception.

The reason for the split-licensing is to ensure that for the vast majority of teams using Substrate to create feature-chains, then all changes can be made entirely in Apache2-licensed code, allowing teams full freedom over what and how they release and giving licensing clarity to commercial teams.

In the interests of the community, we require any deeper improvements made to Substrate's core logic (e.g. Substrate's internal consensus, crypto or database code) to be contributed back so everyone can benefit.

Benchmarking also benchmark for decoding the call

in the benchmarking macro, when user use the syntax: bench_name { $code }: $dispatch_name($origin, $args) verify { $code }, the benchmark only dispatch the call. This PR changes it, instead the benchmark decode the call and dispatch it.

Breaking change

Some benchmark code won't compile complaining about partially moved variables. It should be generally easily fixable using clone.

Implement `pallet-bags-list` and its interfaces with `pallet-staking`
closes https://github.com/paritytech/substrate/issues/9440

polkadot companion https://github.com/paritytech/polkadot/pull/3413

Notes for reviewers

Below is a table describing how an extrinsic would affect an account (relative to SortedListProvider and CounterForNominators) given its role in staking:

| extrinsic | Chilled | Nominator | Validator | |:------------------:|:----------------------:|:----------------------:|------------------------| | chill, chill_other | nothing, nothing | on_remove, dec counter | nothing, nothing | | nominate | on_insert, inc counter | nothing, nothing | on_insert, inc counter | | validate | nothing, nothing | on_remove, dec counter | nothing, nothing | | bond_extra | nothing, nothing | on_update, nothing | nothing, nothing | | rebond | nothing, nothing | on_update, nothing | nothing, nothing | | unbond | nothing, nothing | on_update, nothing | nothing, nothing |

TODO:

[x] update benchmarks of extrinsics that call do_rebag to force a rebag (relates to some work done in https://github.com/paritytech/substrate/pull/9529)

[x] Check the benchmark values for snapshot creation. There are some tests that tell us how many snapshot items we can take in a 2 second block. https://github.com/paritytech/substrate/pull/9507#issuecomment-899466440

[x] Write a remote-externalities-based test that checks the state of polkadot and substrate, and populates the list. Same as testing the migration basically: Done in companion.

[x] Test migration

[ ] (seperate_pr) Make all staking tests work with and without bags-list. For now we use bags-list only, and we do this in a follow up, to prevent a single super big PR.

[x] rename and fix docs, avoid using voter in bags-list, it should be id and vote-weight. Ideally we could also use something like priority instead of vote-weight.

[ ] (maybe+separate PR) Write a fuzzer/quick test that just bombards the SortedListProvider with random data and calls, and the internal state of the pallet should always remain correct. (https://github.com/paritytech/substrate/pull/9851)

[ ] (seperate pr) weight refunds for when the operation does not affect nominators (and thus not the bags list)

[ ] (separate PR) Allow the ability to reorder yourself within a bag.

original description for #9081 below:

Problem: there are too many nominators, we can't keep all of them. Solution: truncate the list by stake.

Problem: an attacker can kick out as many people as they can afford to; those people at the low end would need to re-nominate. Solution: don't actually take them out of the nominator set, but compute the top N members at runtime.

Problem: computing the top N at runtime is expensive. Solution: create many bags, each of which holds voters within a particular stake range. Each bag is a linked list, so it can be added to and removed from in O(1). We can then iterate over the bags in order and truncate anywhere we desire. Given a realistic distribution of stake, it doesn't matter where we stop; the final bag is the one with the lowest-staked individuals.

Get rid of wasm-gc
wasm-gc got deprecated but we still use it in our build pipeline.

The author mentions that:

The Rust compiler now natively supports --gc-sections when linking wasm executables, which means wasm executables already have 90% of their garbage removed when coming out of the compiler.

But for us this is not entirely true and the size of the runtime is:

882K baseline

636K with wasm-gc

And

The wasm-pack (and wasm-bindgen) project will already run this by default for you, so there's no need to run it again.

But we don't use neither of these.

We need to figure out what do we want to use.

BREAKING Overlay transaction support.

BREAKING: this pr adds externalities, and change mutability of existing one, the corresponding

This PR is a refactor of overlay_change to allow transactional support, it is similar to #2980 goals, but does not stack Ext, it only stacks storage.

It also switches from a stack of hashmap (previously prospective and top) to a single hashmap (containing history of values) and a transaction global state. Those values with state are managed with 'historied-data' crate (simple vec of data to query in front of a reference global state).

Under this design access to data is not badly impacted by the number of open transactional layers. I did fuzz this code a bit against a partial simple layered hashmap implementation.

Usage from a runtime with a function, in a similar way as ext_try from #2980, there is the very simple with_transaction function: internally it uses three host functions ext_start_transaction, ext_commit_transaction and ext_discard_transaction. This does not look as good as the single ext_try but is clearer: memory mgmt seems way simplier (as there is none).

Note that to call global state action, modification of local values need to be synchronize. eg discard_transaction on states must be follow by apply_discard_transaction for all values related to this state and then follow by ensure_running.

Technically we only maintain a counter of current number of stacked transaction as a global state (this start at 1 and can be 0 only to update some values: case of discarding content, but will then return to 1 through 'finalize_discard' call). Local state is either committed or the number of stacked transaction when the value was changed, this state is stored with the value history.

pallet-vesting: Support multiple, merge-able vesting schedules
closes: https://github.com/paritytech/substrate/issues/7101 polkadot companion: https://github.com/paritytech/polkadot/pull/3407

Features

Support multiple vesting schedules per account. Each account is allowed up to MaxVestingSchedules, which is a configurable pallet constant.

A user can merge two schedules together to create a new schedule. See the new merge_schedules extrinsic

Follow up work

Look into adding a vesting derive to polkadot-js that helps with understanding the affects of merging a schedule

Metadata with complete type information

This fixes #917, which is one of the biggest pain point to me when working with Substrate (and polkadot.js), that any type information needs to be implemented twice and incompatible type information simply cause polkadot.js crashes without much helpful clues (other than it is mostly likely a codec error).

This introduce type_registry to RuntimeMetadata which contains all the type informations i.e. the metadata itself stores the information about how to decode the storage types.

Ideally, this will remove the needs to manually maintain type information in polkadot.js (currently implemented at https://github.com/polkadot-js/api/tree/master/packages/types/src). Those JS classes can be generated at runtime by parsing the metadata. TS files can be generated ahead-of-time if needed. This will also make implement (and support) other languages SDK much easily.

Some code copied from parity-codec.

Fixes #917 Enable the proper fix for https://github.com/polkadot-js/api/issues/416 Could be the foundation work for https://github.com/polkadot-js/api/issues/429

New Weight Template + Organization

This layout should improve automation of weight generation (reducing from 2 files to 1), and ultimately be way more flexible in terms of the layout and content of the generated files.

Remove `Copy` from `Ensure*` traits
Follow up on https://github.com/paritytech/substrate/pull/12967#discussion_r1059864886 to make BaseArithmetic work with Ensure.
It re-uses the code from EnsureOpAssign in EnsureOp, instead of the other way around, which incurred the Copy requirement.
It does contain an artificial dependence of EnsureOp on EnsureOpAssign to re-use code, but that should be fine since the trait bounds would be the same anyway.

Removes the Copy requirement from:

EnsureOp and EnsureOpAssign

EnsureFrom and EnsureInto: Not sure about this one since we now generate the error in every case. Could be slightly slower.

Implement Ensure for BaseArithmetic instead of EnsureOp + EnsureOpAssign. If I do both then it throws a "conflicting implementation" error.

EPM: Adds emergency phase throttling

WIP, for comments and discussion.

As a follow up from the Kusama incident and our previous discussions, this is a potential direction to fix the knee jerk reaction of EPM to transition to the emergency phase. There were 2 reasons why EPM entered in emergency mode: 1) the staking pallet called election_provider::elect() prematurely due to Forcing::ForceNew, before EPM had enough time to prepare the next election results for the next era; and 2) there was no election fallback configured.

This suggestion adds a MinSignedPhaseDuration config to EPM sets the minimum number of blocks in the signed phase before an election failure results in transitioning to the emergency phase. If the minimum signed block threshold was not reached and the election failed, the emergency phase will not be set. We need to estimate a reasonable number of blocks for EPM +staking miners to prepare a solution during the signed phase. Setting MinSignedPhaseDuration = 0 has a similar behaviour as currently. Calling elect() during Phase::Off also throttles the emergency phase.

The advantage of this PR is that the changes are local to EPM and easy to reason about. This logic is transparent to staking, the difference is that a failed election may self-heal as staking keeps trying to fetch the election results in subsequent sessions.

fix: Fixes substrate-node-template docker issues
[X] Description:

Updates to allow use of either docker-compose v1 or docker compose v2. See difference between each here https://stackoverflow.com/questions/66514436/difference-between-docker-compose-and-docker-compose, noting that a comment at that link suggests users may be able to resolve it by installing the docker-compose-plugin, but i don't think that should be necessary, it needs support for latest docker compose v2. Previously only docker-compose was supported, so if you had installed Docker CE on a linux machine it wouldn't have that executable but it would have the docker compose ... executable and the script would panic. Note that I encountered the issue because I had the latest docker compose from installing Docker CE (i didn't have Docker Desktop because I was using a cloud provider that didn't have the required KVM support, see https://docs.docker.com/desktop/install/linux-install/)

Updates readme to mention what to do if get error listen tcp4 0.0.0.0:9944: bind: address already in use that port 9944 not available in this PR (for example i was running a moonbase collator on that same port, so i changed the port used by that service, but would have been easier just to modify the port mapping in docker-compose.yml to use a different local port)

Previously after you clone the Substrate repository and run ./bin/node-template/scripts/docker_run.sh it would give error error: could not findCargo.tomlin/var/www/node-templateor any parent directory on Ubuntu 22.04, so docker-compose.yml file has been updated in this PR

Previously when it started building with cargo build --release it gave warning warning: use of deprecated associated functionchrono::Local::today: useLocal::now()instead, so that change has been made in this PR

Added bind mount for Git to fix warning when running cargo build --release where warning is warning: Git command failed with status: exit status: 128; warning: Could not find.git/HEADsearching from '/var/www/node-template/node' upwards!

Using printf instead of echo so newline characters work (alternative is echo -e)

Uses multiline yaml format for docker-compose.yml command so not too many chars per line

What important points should reviewers know?

In docker-compose.yml I have used bind mounts instead of volumes. If I used volumes instead then I would have added the following to the nested volumes in docker-compose.yml instead of using type: bind for each instead.

- ../../.git:/var/www/node-template/.git - ../../frame:/var/frame - ../../utils:/var/utils - ../../client:/var/client - ../../primitives:/var/primitives

Note that if I had used volumes instead of bind mounts then I wouldn't have had to add mkdir -p "$PARENT_DIR/.local" in the docker_run.sh file. If neither approaches are followed then it gives error Error response from daemon: invalid mount config for type "bind": bind source path does not exist: ~/substrate/bin/node-template/.local

Is there something left for follow-up PRs?

Suggested further change in docker_run.sh file is to change docker compose run --rm --service-ports dev $@ by removing the --rm so it doesn't delete the container, that way if the user stops the container that automatically starts running they don't lose the container and have to create it again, instead they could just run the following to find and enter the container using the last container that was created, and then inside the container optionally run commands

docker ps -a docker compose -f ./bin/node-template/docker-compose.yml up -d docker exec -it $(docker ps -n=1 -q) /bin/sh

Suggest consider using cargo build ... and target/debug ... for development instead of cargo build --release ... and target/release ... that are for production

Might instead build https://github.com/paritytech/substrate/blob/master/docker/substrate_builder.Dockerfile modified for substrate template instead of using paritytech/ci-linux:production docker image in future?

Upgrade wasm-opt to 0.111.0

This upgrades binaryen to version 111.

Binaryen (and wasm-opt) now enables the SignExt and MutableGlobals features by default, which are also enabled in the LLVM backend. In the future Binaryen will align its default feature selection with the LLVM backend.

This is probably is ok for wasm-builder - wasmi supports both these.

This also points to potential future optimizations by explicitly turning on more features that wasmi supports but that aren't enabled in wasm-opt by default.

Most notably, this is the first release of the new FRAME (2.0) with its new macro-syntax and some changes in types, and pallet versioning. This release also incorporates the faster and improved version 2.0 of the parity-scale-codec and upgraded dependencies all-around. While the FinalityTracker pallet has been dropped, this release marks the first public appearance of a few new pallets, too: Bounties, Lottery, Tips (extracted from the Treasury-pallet, see #7536) and Merkle-Mountain-Ranges (MMR).

On the client side, the most notable changes are around the keystore, making it async and switching to a different signing model allowing for remote-signing to be implemented. Various changes to improve networking and light-client support, like adding the Grandpa warp sync request-response protocol (#7711) are also included.

Contracts: Please note that the contracts pallet is not part of this release. The pallet is not yet ready and will be released separately in the coming weeks. The currently released contracts pallet is not compatible with the new FRAME, thus if you need the contracts pallet, we recommend you wait with the upgrade until it has been released, too.

Upgrade instructions

Not too much has changed on the top and API level for developing Substrate betweeen 2.0 and 3.0. The easiest and quickest path for upgrading is to just take the latest node-template and try applying your changes to it:

take a diff between 2.0 and your changes

store that diff

remove everything, copy over the 3.0 node-template

try re-applying your diff, manually, a hunk at a time.

If that doesn't work for you, we are working on an in-depth-guide for all major changes that took place and how you need to adapt your code for it. You can find the upgrade guide under docs/ in the repo, if you have further questions or problems, please feel free to ask in the github discussion board.
