🧹 Outside diff range and nitpick comments (10)
packages/rs-sdk/src/core/mod.rs (1)
4-5: LGTM! Consider adding a brief module documentation.The addition of the
dash_core_clientmodule, conditionally compiled with the "mocks" feature, aligns well with the PR objective of creating an abstraction layer for mock implementations. This change enhances the modularity of the code and allows for better testing capabilities.Consider adding a brief documentation comment above the module declaration to explain its purpose and when it's used. For example:
/// Module containing mock implementations for the Dash Core client. /// Only compiled when the "mocks" feature is enabled. #[cfg(feature = "mocks")] mod dash_core_client;packages/rs-sdk/src/internal/sync.rs (2)
7-12: LGTM: Well-structured error enum with a minor suggestion.The
AsyncErrorenum is well-defined and uses appropriate derive macros and error handling practices.Consider adding a comment explaining why the
Genericvariant is currently unused and marked with#[allow(unused)]. This will help future maintainers understand the intention behind this variant.
26-32: LGTM with a suggestion: Consider enhancing error handling in block_on function.The
block_onfunction provides a clean way to execute asynchronous code in a synchronous context. The function signature withSendand'staticbounds ensures thread safety.Consider enhancing the error handling to catch potential panics during future execution. This can be achieved using
std::panic::catch_unwind. Here's a suggested implementation:pub(crate) fn block_on<F: Future + Send + 'static>(fut: F) -> Result<F::Output, AsyncError> where F::Output: Send, { std::panic::catch_unwind(|| futures::executor::block_on(fut)) .map_err(|_| AsyncError::Generic("Future panicked during execution".to_string())) .and_then(|result| Ok(result)) }This implementation will catch panics and convert them into
AsyncError, providing more robust error handling.packages/rs-sdk/src/lib.rs (1)
66-66: Approve the addition of theinternalmodule and suggest documentation updates.The addition of the
internalmodule is a good practice for encapsulating implementation details. This change likely improves the SDK's structure by separating internal components from the public API.Consider updating the module-level documentation to briefly mention the purpose of the new
internalmodule, even though it's not publicly exported. This will help maintainers understand the module's role in the SDK's architecture.packages/rs-drive-proof-verifier/src/error.rs (1)
109-112: LGTM! Consider a minor improvement for consistency.The addition of the
AsyncErrorvariant is well-implemented and aligns with the PR objectives to improve async processing. The error message is clear and informative.For consistency with other variants in the enum, consider using a named field instead of a tuple variant:
#[error("async error: {error}")] AsyncError { error: String },This change would make it consistent with variants like
GenericandConfig.packages/rs-sdk/src/core/dash_core_client.rs (2)
30-30: Update Comments and Error Messages to Reflect Struct RenamingThe struct has been renamed to
LowLevelDashCoreClient, but there are still references toCoreClientin comments and error messages. Specifically:
- Line 30: The comment refers to
CoreClientinstead ofLowLevelDashCoreClient.- Line 38: The
expecterror message mentionsCoreClient.Please update these references to maintain consistency.
Apply this diff to correct the references:
impl Clone for LowLevelDashCoreClient { - // As Client does not implement Clone, we just create a new instance of CoreClient here. + // As Client does not implement Clone, we create a new instance of LowLevelDashCoreClient here. fn clone(&self) -> Self { LowLevelDashCoreClient::new( &self.server_address, self.core_port, &self.core_user, &self.core_password, ) - .expect("Failed to clone CoreClient when cloning, this should not happen") + .expect("Failed to clone LowLevelDashCoreClient; this should not happen") } }Also applies to: 38-38
Line range hint
42-49: Incorrect Struct Name inDebugImplementationIn the
Debugimplementation forLowLevelDashCoreClient, thedebug_structmethod is called with"CoreClient"instead of"LowLevelDashCoreClient". This could lead to confusion when debugging.Apply this diff to fix the struct name:
impl Debug for LowLevelDashCoreClient { fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result { - f.debug_struct("CoreClient") + f.debug_struct("LowLevelDashCoreClient") .field("server_address", &self.server_address) .field("core_user", &self.core_user) .field("core_port", &self.core_port) .finish() } }packages/rs-sdk/src/mock/sdk.rs (1)
422-422: Use&Pathinstead of&PathBuffor the parameterpath.Since
PathBufdereferences toPath, accepting a&Pathis more idiomatic and allows for more flexibility.Apply this diff to update the parameter type:
- path: &PathBuf, + path: &Path,Also, update any internal usage of
pathif necessary.packages/rs-sdk/src/sdk.rs (2)
Line range hint
798-811: Simplify context provider setup to avoid unnecessary cloningIn the context provider setup, cloning
context_providerand wrapping it in bothArcandBoxmay be redundant. Consider simplifying to:- sdk.context_provider.swap(Some(Arc::new(Box::new(context_provider.clone())))); + sdk.context_provider.swap(Some(Arc::new(Box::new(context_provider))));Since
context_provideris newly created and not shared yet, cloning may not be necessary.
850-850: UseArcSwapOptioninstead ofArcSwapAnyfor consistencyFor consistency with the rest of the codebase, consider using
ArcSwapOptionwhen initializingcontext_provider:- context_provider: ArcSwapAny::new(Some(Arc::new(context_provider))), + context_provider: ArcSwapOption::new(Some(Arc::new(context_provider))),This maintains consistency and readability.

26-26: Great use ofZeroizingfor password protection!The change from
StringtoZeroizing<String>forcore_passwordis an excellent security improvement. It ensures that the password is automatically zeroed out in memory when it's no longer needed, reducing the risk of sensitive data exposure.Consider adding a comment explaining the use of
Zeroizingfor future maintainers:// Dash Core RPC password #[arg(short = 'p', long)] +// Uses Zeroizing to automatically clear the password from memory when no longer needed pub core_password: Zeroizing<String>,packages/rs-sdk/src/core/dash_core_client.rs (4)
22-27: Approved: Improved struct naming and securityThe renaming of
CoreClienttoLowLevelDashCoreClientprovides a more descriptive name, clearly indicating its low-level nature. The addition ofcore_passwordusingZeroizing<String>is an excellent security improvement.Consider adding a brief comment above the
core_passwordfield to explain its security implications:/// Securely stored core password that is automatically zeroed when dropped core_password: Zeroizing<String>,
30-41: Approved: CorrectCloneimplementationThe
Cloneimplementation forLowLevelDashCoreClientis correct and necessary, given thatClientdoesn't implementClone. This approach maintains the integrity of thecorefield.Consider making the error message in the
expectcall more specific:.expect("Failed to create new LowLevelDashCoreClient instance during cloning")This provides more context about what operation failed and where.
Line range hint
43-51: Approved: SecureDebugimplementation with minor correction neededThe
Debugimplementation forLowLevelDashCoreClientcorrectly avoids exposing the sensitivecore_passwordfield, which is a good security practice.Update the struct name in the debug output to match the new name:
f.debug_struct("LowLevelDashCoreClient")This ensures consistency with the renamed struct.
Line range hint
53-81: Approved: Updated initialization with security improvementThe changes to the
newmethod are consistent with the struct renaming and the newZeroizingwrapper forcore_password, which improves security.Consider updating the method signature and documentation to reflect the use of
Zeroizing:/// Create new Dash Core client. /// /// # Arguments /// /// * `server_address` - Dash Core server address. /// * `core_port` - Dash Core port. /// * `core_user` - Dash Core user. /// * `core_password` - Dash Core password (will be securely stored). pub fn new( server_address: &str, core_port: u16, core_user: &str, core_password: impl Into<Zeroizing<String>>, ) -> Result<Self, Error> { // ... (rest of the implementation) Ok(Self { // ... (other fields) core_password: core_password.into(), // ... (rest of the struct initialization) }) }This change allows the caller to pass either a
Stringor aZeroizing<String>for thecore_password, providing flexibility while ensuring secure storage.packages/rs-sdk/tests/fetch/config.rs (1)
Line range hint
115-119: Consider adding a clarifying commentThe
is_emptymethod correctly handles the newZeroizing<String>type forcore_password. However, it might be helpful to add a comment explaining thatZeroizing<String>implementsDeref, allowing it to be used like a regularString. This would improve code clarity for future maintainers.Consider adding a comment like this:
// Note: Zeroizing<String> implements Deref, so we can call is_empty() on it directly self.core_password.is_empty()packages/rs-sdk/src/mock/sdk.rs (2)
86-95: LGTM: Deprecation and implementation ofload_expectations.The deprecation of
load_expectationsin favor ofload_expectations_syncaligns with the PR objective. The implementation maintains backward compatibility by calling the new synchronous method internally.Consider adding a deprecation warning message to the method documentation to make it more visible to users:
/// Load all expectations from files in a directory asynchronously. /// /// See [MockDashPlatformSdk::load_expectations_sync()] for more details. #[deprecated(since = "1.4.0", note = "use load_expectations_sync")] #[doc(hidden)] pub async fn load_expectations<P: AsRef<std::path::Path> + Send + 'static>( &mut self, dir: P, ) -> Result<&mut Self, Error> { eprintln!("Warning: `load_expectations` is deprecated.

Line range hint
104-201: LGTM: Refactoredload_expectations_syncmethod.The changes to
load_expectations_sync(formerlyload_expectations) align with the PR objective of improving async processing. The use ofblock_onto lock thedapiclient synchronously and the introduction of theload_expectationfunction for each file type improve the code structure and eliminate the need for awaiting.Consider adding error handling for the
block_oncall:let mut dapi = block_on(self.dapi.clone().lock_owned()).map_err(|e| { Error::Config(format!("Failed to lock dapi client: {}", e)) })?;This will provide more informative error messages if the locking operation fails.

90-92: Good practice: Removed unnecessary mutabilityRemoving the
mutkeyword from thesdkvariable declaration is a positive change. It adheres to Rust's principle of using immutability by default, which can help prevent accidental modifications and make the code's intent clearer.packages/rs-sdk/src/core/dash_core_client.rs (1)
17-17: Excellent security improvement!The addition of
Zeroizingfrom thezeroizecrate addresses the previous security concern about storing passwords in plain text. This wrapper will automatically zero out sensitive data when it's no longer needed, significantly enhancing the security of theLowLevelDashCoreClient.packages/rs-sdk/tests/fetch/config.rs (3)
14-14: Improved security with Zeroizing importThe addition of
use zeroize::Zeroizing;is a positive change. This import introduces a type designed to handle sensitive data more securely by automatically zeroing out the memory when the data is no longer needed. This is particularly important for sensitive information like passwords.
47-47: Enhanced security for core_passwordChanging the
core_passwordfield type fromStringtoZeroizing<String>is an excellent security improvement. This modification ensures that the password string is automatically zeroed in memory when it goes out of scope, reducing the risk of sensitive data exposure.

101-101: Improved thread-safety and efficiency in context provider management.The change from
Option<Arc<Box<dyn ContextProvider>>>toArcSwapOption<Box<dyn ContextProvider>>for thecontext_providerfield is a good improvement. This allows for atomic swaps of the context provider instance, enhancing concurrency without requiring locks for reads. It provides better performance in multi-threaded scenarios where the context provider might need to be updated.
109-122: Correct implementation ofCloneforSdkstruct.The custom
Cloneimplementation for theSdkstruct is well-implemented. It correctly handles the newArcSwapOption<Box<dyn ContextProvider>>field by usingArcSwapOption::new(self.context_provider.load_full()). This ensures that the cloning process respects the atomic nature of thecontext_provider. All other fields are cloned appropriately as well.
220-221: Thread-safe access to context provider in parsing methods.The modifications to
parse_proof,parse_proof_with_metadata, andparse_proof_with_metadata_and_proofmethods now useload()on the context provider. This change ensures thread-safe access to the provider, which is crucial for maintaining consistency in concurrent scenarios.Also applies to: 260-261
281-283: Improvedcontext_providermethod.The
context_providermethod has been updated to correctly handle the newArcSwapOptiontype. It now returns anOption<impl ContextProvider>, which accurately represents the possibility of a context provider being present or not.
513-515: Thread-safe update of context provider.The
set_context_providermethod now usesswapinstead of direct assignment. This is the correct way to update anArcSwapOption, ensuring that the update is atomic and thread-safe.
588-588: Enhanced security for core password.The use of
Zeroizing<String>for thecore_passwordfield is a good security practice. This ensures that the password is securely erased from memory when it's no longer needed, reducing the risk of sensitive data exposure.Also applies to: 747-747
851-851: Ensure consistent error handling in mock mode.In the mock mode initialization, make sure that the error handling for loading expectations is consistent with the rest of the SDK. Consider propagating any errors that occur during
load_expectations_syncinstead of potentially ignoring them.Also applies to: 857-857

52-56: Consider using a constant for defaultcore_fee_per_byteThe
core_fee_per_byteparameter uses a default value of 1 if not provided. To improve maintainability, consider defining this default value as a constant at the module or struct level. This would make it easier to update if needed and provide a clear, named value for this default.You could add a constant at the top of the file or in a configuration module:
const DEFAULT_CORE_FEE_PER_BYTE: u32 = 1;Then use it in the method:
core_fee_per_byte.unwrap_or(DEFAULT_CORE_FEE_PER_BYTE),This change would make the code more maintainable and self-documenting.

44-44: Security Enhancement: Use ofZeroizingforcore_passwordThe introduction of
Zeroizingfor thecore_passwordfield ensures that sensitive data is securely zeroed out from memory when no longer needed. This is a good practice for handling credentials and enhances the security of the SDK.
101-101: Updatecontext_providertoArcSwapOptionfor Thread SafetyChanging the
context_providerfield toArcSwapOption<Box<dyn ContextProvider>>allows for atomic, thread-safe updates without requiring mutable access. This enhances concurrency and simplifies the usage ofcontext_provideracross multiple threads.
109-122: Verify Cloning ofArcSwapOptioninSdk::CloneImplementationIn the
Cloneimplementation forSdk, thecontext_provideris cloned using:context_provider: ArcSwapOption::new(self.context_provider.load_full()),Ensure that this cloning mechanism correctly duplicates the internal state of
ArcSwapOptionand that the new instance shares the same underlying data safely. This is important to prevent unintended side effects or concurrency issues.
261-263: Consistent Error Handling for Missingcontext_providerSimilar to previous methods, ensure that the error handling for a missing
context_provideris consistent and refactored appropriately to avoid code duplication.
279-285: Efficient Retrieval ofcontext_providerThe
context_providermethod now usesArcSwapOptionto load the provider:let provider_guard = self.context_provider.load(); let provider = provider_guard.as_ref().map(Arc::clone);This approach ensures thread-safe access without requiring locks, improving performance in concurrent environments.
626-626: Initializecore_passwordwithZeroizing<String>The
core_passwordfield inSdkBuilderis now initialized usingZeroizing<String>:core_password: "".to_string().into(),This change enhances security by ensuring that the password is zeroed out from memory when it is no longer needed.
749-749: Secure Assignment ofcore_passwordUsingZeroizingIn the
with_coremethod, thecore_passwordis assigned usingZeroizing:self.core_password = Zeroizing::from(password.to_string());This ensures that the password is securely managed and reduces the risk of sensitive data exposure.
794-794: Proper Initialization ofcontext_providerwithArcSwapOptionDuring the SDK build process, the
context_provideris initialized using:context_provider: ArcSwapOption::new(self.context_provider.map(Arc::new)),This aligns with the updated type and ensures that the context provider can be atomically swapped if needed.

514-516: LGTM: Improved thread-safe context provider setting, but note breaking changeThe
set_context_providermethod has been updated to use&selfinstead of&mut self, allowing for setting the context provider without requiring mutable access to theSdkinstance. The implementation correctly usesswapfor the newArcSwapOptiontype.However, this is a breaking change that may affect existing code using this method. Ensure this change is clearly communicated in the release notes and consider updating the version number appropriately.
Consider adding a deprecation notice for the old method signature if backward compatibility is a concern, and provide migration guidelines in the documentation.

1-875: Overall improvements in thread safety and security, with breaking changesThe changes in this file significantly enhance the thread safety and security of the SDK:
- The use of
ArcSwapOptionfor the context provider improves concurrent access.- The
set_context_providermethod now allows for thread-safe updates without requiring mutable access.- The
context_providermethod ensures thread-safe access to the provider.- The use of
Zeroizing<String>for the core password inSdkBuilderimproves security.However, there are breaking changes, particularly in the
set_context_providermethod signature.Consider the following recommendations:
- Update the crate's version number according to semantic versioning principles, likely requiring a major version bump.
- Clearly document the breaking changes in the release notes and provide migration guidelines for users.
- If backwards compatibility is a concern, consider providing deprecated versions of changed methods with the old signatures, guiding users towards the new implementations.
- Update any relevant documentation or examples to reflect these changes, especially regarding the new thread-safe context provider usage.

101-101: LGTM: Improved thread safety for context providerThe change from
Option<Arc<Box<dyn ContextProvider>>>toArcSwapOption<Box<dyn ContextProvider>>enhances thread safety by allowing atomic operations on the context provider. This is a valuable improvement for concurrent access scenarios.
109-122: LGTM: Correct implementation of Clone for SdkThe custom
Cloneimplementation forSdkis well-implemented. It properly handles the cloning of all fields, including the newArcSwapOption<Box<dyn ContextProvider>>. This ensures that thecontext_provideris correctly shared across clones, maintaining thread safety and consistency.
279-284: LGTM: Thread-safe context provider accessThe
context_providermethod has been updated to useload()for accessing the context provider, ensuring thread-safe access. Returning anOption<impl ContextProvider>is appropriate, as it correctly handles the case where the context provider may not be set. These changes are consistent with the newArcSwapOptiontype and improve the overall thread safety of the SDK.
589-589: LGTM: Enhanced security for core passwordThe change from
StringtoZeroizing<String>for thecore_passwordfield inSdkBuilderis a significant security improvement.Zeroizingensures that the password is securely erased from memory when it's no longer needed, reducing the risk of sensitive data exposure in case of memory dumps or other security vulnerabilities.
