From f8807d1e185ccd281052106599a2c55694d02fc1 Mon Sep 17 00:00:00 2001 From: Iulian Barbu <14218860+iulianbarbu@users.noreply.github.com> Date: Sat, 5 Oct 2024 15:28:04 +0300 Subject: [PATCH] templates: add genesis config presets for minimal/solochain (#5868) # Description Closes [#5790](https://github.com/paritytech/polkadot-sdk/issues/5790). Useful for starting nodes based on minimal/solochain when doing development or for testing omni node with less happy code paths. It is reusing the presets defined for the nodes chain specs. ## Integration Specifically useful for development/testing if generating chain-specs for `minimal` or `solochain` runtimes from `templates` directories. ## Review Notes Added `genesis_config_presets` modules for both minimal/solochain. I reused the presets defined in each node `chain_spec` module correspondingly. ### PRDOC Not sure who uses templates, maybe node devs and runtime devs at start of their learning journey, but happy to get some guidance on how to write the prdoc if needed. ### Thinking out loud I saw concerns around sharing functionality for such genesis config presets between the template chains. I think there might be a case for doing that, on the lines of this comment: https://github.com/paritytech/polkadot-sdk/pull/4739#issuecomment-2157341035. I would add that `parachains-common::genesis_config_heleper` contains a few methods from those mentioned, but I am unsure if using it as a dependency for templates is correct. Feels like the comment suggests there should be a `commons` crate concerning just `templates`, which I agree with to some degree, if we assume `cumulus` needs might be driven in certain directions that are not relevant to `templates` and vice versa. However I am not so certain about this, so would welcome some thoughts, since I am seeing `parachains-common` being used already in a few runtime implementations: https://crates.io/crates/parachains-common/reverse_dependencies?page=3, so might be a good candidate already for the `common` logic. --------- Signed-off-by: Iulian Barbu --- Cargo.lock | 4 + templates/minimal/node/src/chain_spec.rs | 22 +--- templates/minimal/node/src/command.rs | 2 +- templates/minimal/runtime/Cargo.toml | 2 + templates/minimal/runtime/src/lib.rs | 54 ++++++++- templates/parachain/node/src/chain_spec.rs | 4 +- templates/parachain/node/src/command.rs | 6 +- templates/parachain/runtime/Cargo.toml | 2 +- templates/solochain/node/Cargo.toml | 5 +- templates/solochain/node/src/chain_spec.rs | 98 +-------------- templates/solochain/node/src/command.rs | 4 +- templates/solochain/runtime/Cargo.toml | 4 + templates/solochain/runtime/src/apis.rs | 6 +- .../runtime/src/genesis_config_presets.rs | 112 ++++++++++++++++++ templates/solochain/runtime/src/lib.rs | 2 + 15 files changed, 197 insertions(+), 130 deletions(-) create mode 100644 templates/solochain/runtime/src/genesis_config_presets.rs diff --git a/Cargo.lock b/Cargo.lock index 568d642879bf..119a8b3afed2 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -9592,6 +9592,7 @@ dependencies = [ "parity-scale-codec", "polkadot-sdk", "scale-info", + "serde_json", ] [[package]] @@ -21246,6 +21247,7 @@ dependencies = [ "sp-consensus-aura", "sp-consensus-grandpa", "sp-core 28.0.0", + "sp-genesis-builder", "sp-inherents", "sp-io 30.0.0", "sp-keyring", @@ -21277,6 +21279,7 @@ dependencies = [ "pallet-transaction-payment-rpc-runtime-api", "parity-scale-codec", "scale-info", + "serde_json", "sp-api 26.0.0", "sp-block-builder", "sp-consensus-aura", @@ -21284,6 +21287,7 @@ dependencies = [ "sp-core 28.0.0", "sp-genesis-builder", "sp-inherents", + "sp-keyring", "sp-offchain", "sp-runtime 31.0.1", "sp-session", diff --git a/templates/minimal/node/src/chain_spec.rs b/templates/minimal/node/src/chain_spec.rs index 0646460acef6..17b98137b416 100644 --- a/templates/minimal/node/src/chain_spec.rs +++ b/templates/minimal/node/src/chain_spec.rs @@ -15,13 +15,11 @@ // See the License for the specific language governing permissions and // limitations under the License. -use minimal_template_runtime::{BalancesConfig, SudoConfig, WASM_BINARY};
