8-8: Ohayo! Nice move to Arc!The transition to
Arc<ChainSpec>is a good choice for shared ownership of the chain specification. This change aligns well with Rust's memory management best practices for shared, immutable data.Consider adding a doc comment explaining why
Arcis used here, something like:/// The chain specification. + /// Uses Arc for shared ownership across multiple components. pub chain: Arc<ChainSpec>,Also applies to: 25-25

200-201: Consider more concise gas price configurationThe gas price configuration could be simplified using struct update syntax.
- let gas_oracle = if let Some(fixed_prices) = &config.dev.fixed_gas_prices { - L1GasOracle::fixed(fixed_prices.gas_price.clone(), fixed_prices.data_gas_price.clone()) + let gas_oracle = if let Some(prices) = &config.dev.fixed_gas_prices { + L1GasOracle::fixed(prices.gas_price, prices.data_gas_price)

129-129: Ohayo sensei! Clean adaptation to Arc!
The use of .into() for the chain field nicely handles the conversion to Arc<ChainSpec>. The change maintains clean code structure while adapting to the new type requirement.

36-36: Ohayo! Arc change looks good, but let's verify usage!
The transition to Arc<ChainSpec> in the Backend struct is consistent with the changes in other files and appropriate for shared ownership.
Let's verify that all usages of chain_spec in the Backend methods handle Arc correctly:
✅ Verification successful
Let me try a more specific pattern for ast-grep:
Ohayo! The Arc usage looks safe, sensei!
From the search results, we can see that chain_spec is only accessed once in the Backend implementation through self.chain_spec.version.clone(), which is the correct way to handle an Arc field. The other occurrences are just in type definitions and imports.
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Check all usages of chain_spec in Backend methods
# Look for any potential dereferencing or cloning that might need adjustment
ast-grep --pattern 'impl<$_> Backend<$_> {

chain_spec.$$$

}'
Length of output: 76
Script:
#!/bin/bash
# Let's try a different approach to find Backend implementations and chain_spec usage
# First find the file containing Backend implementations
rg -l "impl.*Backend" crates/katana/core/src/
# Then look at the actual implementations
rg -A 10 "impl.*Backend" crates/katana/core/src/
# Also search for direct chain_spec usage

91-91: LGTM! Nice consolidation of config fields, sensei!
The change to use Arc<Config> is a good optimization that reduces memory overhead and simplifies configuration management.
104-104: Clean config access pattern!
The updated configuration access through self.config is consistent and well-structured.
Also applies to: 131-131
181-183: 🛠️ Refactor suggestion
Consider safer chain spec mutation approach
The Arc::get_mut call assumes exclusive ownership. This could fail if there are other references to the Arc.
Consider using a builder pattern or constructing the chain spec before wrapping in Arc:
- let chain_spec = Arc::get_mut(&mut config.chain).expect("get mut Arc");
- let (bc, block_num) = Blockchain::new_from_forked(cfg.url.clone(), cfg.block, chain_spec).await?;
+ let mut chain_spec = (*config.chain).clone();
+ let (bc, block_num) = Blockchain::new_from_forked(cfg.url.clone(), cfg.block, &mut chain_spec).await?;
+ config.chain = Arc::new(chain_spec);✅ Verification successful
Let me verify the usage of config.chain further by checking how the Blockchain type handles the chain spec.
Ohayo sensei! After analyzing the implementation, I can now provide the final response:
The Arc::get_mut usage is safe here
The new_from_forked method needs mutable access to modify the chain spec with forked block data (timestamps, gas prices, etc). The Arc is only used for configuration and there are no other references to it at this point in the initialization flow.
Looking at the codebase:
- The chain spec is only used during initialization
- Other usages of
config.chainare read-only accesses - The mutation is necessary to properly set up the forked chain state

Line range hint 207-233: Ohayo! Clean Arc implementation for chain spec!
The change to return Arc<ChainSpec> aligns well with the overall memory optimization strategy while maintaining the existing functionality.
