server/v2/types.go (1)
20-23: Summary of interface changes and their impact.The changes to the
AppI[T transaction.Tx]interface consistently remove the "Get" prefix from four method names:AppManager(),QueryHandlers(),Store(), andSchemaDecoderResolver(). These changes align well with Go naming conventions and improve the overall readability of the interface.While these changes enhance code quality, they may have a widespread impact on the codebase. Ensure that all implementations of this interface and all calls to these methods throughout the project are updated accordingly.
Consider running a project-wide search and replace operation to update all occurrences of these method names. Additionally, if this is a public API, make sure to document these changes clearly in the changelog and update any relevant documentation or examples.

844-844: Consider documenting the new error handling approach.The addition of the
errorfield tostfRouterWrappersuggests a shift in error handling strategy. This allows for accumulating multiple errors during the registration process, which can be beneficial for comprehensive error reporting.Consider adding a comment explaining this new error handling approach and how it should be used. Also, ensure that all methods using this struct are updated to handle the accumulated errors appropriately.
Line range hint
855-863: LGTM! Consider a small optimization.The changes in the
RegisterHandlermethod are consistent with the new error accumulation approach. Storing successfully registered handlers in thehandlersmap is a good practice for later retrieval or validation.Consider initializing the
handlersmap in the struct's constructor or when the struct is first created, rather than checking and initializing it in every call toRegisterHandler. This would slightly improve performance and simplify the method:type stfRouterWrapper struct { stfRouter *stf.MsgRouterBuilder error error - handlers map[string]appmodulev2.Handler + handlers map[string]appmodulev2.Handler = make(map[string]appmodulev2.Handler) } func (s *stfRouterWrapper) RegisterHandler(handler appmodulev2.Handler) { // ... existing code ... - if s.error == nil { - s.handlers = map[string]appmodulev2.Handler{} - } s.handlers[requestName] = handler }runtime/v2/app.go (2)
148-148: Correct the typo in the method comment forAppManagerThe comment for the
AppManagermethod contains a typo: "appamanger" should be "AppManager". Additionally, ensuring the correctness of comments enhances code readability and maintainability.Apply this diff to correct the typo:
-// AppManager returns the app's appamanger +// AppManager returns the app's AppManager
153-153: Update the method comment to match the method nameQueryHandlersThe comment for the
QueryHandlersmethod still references the old method nameGetQueryHandlers. To maintain consistency and clarity, please update the comment to reflect the current method name.Apply this diff to update the comment:
-// GetQueryHandlers returns the query handlers. +// QueryHandlers returns the query handlers.server/v2/appmanager/appmanager.go (7)
43-49: Reorder parameters in the constructor for clarityConsider reordering the parameters in the
NewAppManagerfunction to group related parameters together. PlacinginitGenesisImplandexportGenesisImplafterstfimproves readability by grouping configuration parameters followed by function implementations.Apply this diff to reorder the parameters:
func NewAppManager[T transaction.Tx]( config Config, db Store, stf StateTransitionFunction[T], + initGenesisImpl InitGenesis, + exportGenesisImpl ExportGenesis, - initGenesisImpl InitGenesis, - exportGenesisImpl ExportGenesis, ) (*AppManager[T], error) {
31-36: Simplify struct field comments following Go conventionsPer the Uber Golang style guide, comments for struct fields should be concise and begin with the field name. The current comments are verbose and include parameter details, which are more suitable for function documentation. Consider simplifying these comments to make them more concise.
Apply the following changes:
-// InitGenesis is a function that initializes the application state from a genesis file. -// It takes a context, a source reader for the genesis file, and a transaction handler function. +// initGenesis initializes the application state from a genesis file. initGenesis InitGenesis -// ExportGenesis is a function that exports the application state to a genesis file. -// It takes a context and a version number for the genesis file. +// exportGenesis exports the application state to a genesis file. exportGenesis ExportGenesis
Line range hint
71-208: Use pointer receivers for methods to avoid unnecessary copyingThe methods
InitGenesis,ExportGenesis,DeliverBlock,ValidateTx,Simulate,Query, andQueryWithStatehave value receivers(a AppManager[T]). SinceAppManageris a struct with multiple fields, using value receivers may result in unnecessary copying on each method call. To optimize performance, consider changing the receivers to pointers.Apply the following diff:
-func (a AppManager[T]) InitGenesis( +func (a *AppManager[T]) InitGenesis( -func (a AppManager[T]) ExportGenesis(ctx context.Context, version uint64) ([]byte, error) { +func (a *AppManager[T]) ExportGenesis(ctx context.Context, version uint64) ([]byte, error) { -func (a AppManager[T]) DeliverBlock( +func (a *AppManager[T]) DeliverBlock( -func (a AppManager[T]) ValidateTx(ctx context.Context, tx T) (server.TxResult, error) { +func (a *AppManager[T]) ValidateTx(ctx context.Context, tx T) (server.TxResult, error) { -func (a AppManager[T]) Simulate(ctx context.Context, tx T) (server.TxResult, corestore.WriterMap, error) { +func (a *AppManager[T]) Simulate(ctx context.Context, tx T) (server.TxResult, corestore.WriterMap, error) { -func (a AppManager[T]) Query(ctx context.Context, version uint64, request transaction.Msg) (transaction.Msg, error) { +func (a *AppManager[T]) Query(ctx context.Context, version uint64, request transaction.Msg) (transaction.Msg, error) { -func (a AppManager[T]) QueryWithState(ctx context.Context, state corestore.ReaderMap, request transaction.Msg) (transaction.Msg, error) { +func (a *AppManager[T]) QueryWithState(ctx context.Context, state corestore.ReaderMap, request transaction.Msg) (transaction.Msg, error) {
Line range hint
95-102: Add nil check forinitGenesisinInitGenesismethodIn the
InitGenesismethod,a.initGenesisis used without checking if it is nil. This could lead to anilpointer dereference ifinitGenesiswas not properly initialized. Similar to theExportGenesismethod, consider adding a nil check before usinga.initGenesis.Apply the following diff:
func (a *AppManager[T]) InitGenesis( ctx context.Context, blockRequest *server.BlockRequest[T], initGenesisJSON []byte, txDecoder transaction.Codec[T], ) (*server.BlockResponse, corestore.WriterMap, error) { + if a.initGenesis == nil { + return nil, nil, errors.New("init genesis function not set") + } var genTxs []T
Line range hint
112-115: Handle potential error when applying state changesAfter applying the state changes in the
InitGenesismethod, the returned errorerris used directly in the return statement. IfApplyStateChangesreturns an error,blockResponsewill benil, potentially causing issues downstream. Ensure that the error is handled appropriately, and consider returningblockResponseonly when no error has occurred.Apply the following diff:
err = genesisState.ApplyStateChanges(stateChanges) if err != nil { return nil, nil, fmt.Errorf("failed to apply block zero state changes to genesis state: %w", err) } -return blockResponse, genesisState, err +return blockResponse, genesisState, nil
Line range hint
153-160: Simplify version check inDeliverBlockmethodIn the
DeliverBlockmethod, the version check can be simplified for clarity. Instead of checkinglatestVersion+1 != block.Height, consider using an explicit error message whenblock.Heightis not the next expected height.Apply the following diff:
if latestVersion+1 != block.Height { - return nil, nil, fmt.Errorf("invalid DeliverBlock height wanted %d, got %d", latestVersion+1, block.Height) + return nil, nil, fmt.Errorf("expected block height %d, but got %d", latestVersion+1, block.Height) }
31-41: Group related struct fields togetherFor better readability, consider grouping related fields in the
AppManagerstruct. Place the function fields (initGenesis,exportGenesis,stf) together, and the data fields (config,db) together.Apply the following diff:
// AppManager is a coordinator for all things related to an application type AppManager[T transaction.Tx] struct { // Gas limits for validating, querying, and simulating transactions. config Config + // The database for storing application data. + db Store // InitGenesis initializes the application state from a genesis file. initGenesis InitGenesis // ExportGenesis exports the application state to a genesis file. exportGenesis ExportGenesis // The state transition function for processing transactions. stf StateTransitionFunction[T] - // The database for storing application data. - db Store }

32-41: LGTM with a minor suggestion for error handlingThe changes look good and align with the PR objectives of simplifying the app manager. The use of
app.Store()instead ofapp.GetStore()is consistent with the refactoring goals.A minor suggestion for improvement:
Consider combining the error check for
StateAtwith the one forReadto reduce nesting and improve readability:readerMap, err := app.Store().StateAt(latestHeight) if err != nil { return exportedApp, err } genesisCtx := services.NewGenesisContext(readerMap) if err := genesisCtx.Read(ctx, func(ctx context.Context) error { exportedApp.Validators, err = staking.WriteValidators(ctx, app.StakingKeeper) return err }); err != nil { return exportedApp, err }This change would flatten the error handling structure slightly.

26-29: Evaluate the impact of changingappManagerfield to value type.The
appManagerfield in theDefaultHandlerstruct has been changed from a pointer type to a value type. This change aligns with the modification in theNewDefaultHandlerfunction, but it's crucial to consider the following:
- Memory usage: If
AppManageris a large struct, storing it by value in eachDefaultHandlerinstance could increase memory consumption.- Performance: Operations that modify the
AppManagermight now create copies instead of modifying the original, potentially affecting performance.- Concurrency: This change might affect how
AppManageris shared across goroutines if that was a consideration in the original design.To assess the impact of this change, you can run the following script:
#!/bin/bash # Description: Analyze AppManager usage within DefaultHandler methods # Search for DefaultHandler methods echo "Searching for DefaultHandler methods:" ast-grep --lang go --pattern $'type DefaultHandler[T transaction.Tx] struct { $$$ } func (h *DefaultHandler[T]) $$$($$$) $$$' # Search for appManager usage within DefaultHandler methods echo "\nSearching for appManager usage within DefaultHandler methods:" rg --type go "func \(h \*DefaultHandler\[T\]\)" -A 10 | rg "h\.appManager"This will help identify how
appManageris used withinDefaultHandlermethods and potential areas that might need adjustment due to this change.
23-25: Consider the implications of changingappManagerfrom pointer to value type.The function signature has been modified to accept
appManageras a value instead of a pointer. While this change is consistent with the modification in theDefaultHandlerstruct, it's important to consider the following:
- Performance: If
AppManageris a large struct, passing it by value might impact performance.- Consistency: Ensure this change is reflected consistently across the codebase.
- Intended behavior: Confirm that passing
AppManagerby value aligns with the intended usage and doesn't introduce any unexpected side effects.To verify the impact of this change, you can run the following script:

110-110: Clarify the purpose and impact of the newgetProtoRegistryfield.A new field
getProtoRegistryhas been added to theConsensusstruct initialization:getProtoRegistry: sync.OnceValues(gogoproto.MergedRegistry),This addition introduces new functionality related to protocol buffers registry. The use of
sync.OnceValuessuggests that the merged registry will be computed only once and then cached for subsequent uses.Please provide more context on:
- The purpose of this new field and how it will be used within the
Consensusstruct.- Any performance considerations or benefits this caching mechanism provides.
- Whether this change requires any additional error handling or affects the behavior of other methods in the struct.
#!/bin/bash # Check for usages of getProtoRegistry in the codebase rg --type go 'getProtoRegistry'
80-80: Update all calls toNewConsensusfunction.The
appparameter in theNewConsensusfunction has been changed from a pointer type to a value type. This change is consistent with the modification in theConsensusstruct. However, it requires updating all calls toNewConsensusthroughout the codebase to passAppManagerby value instead of by pointer.Please ensure that all instances where
NewConsensusis called have been updated to reflect this change.#!/bin/bash # Check for any remaining calls to NewConsensus with a pointer AppManager rg --type go 'NewConsensus\([^)]*\*appmanager\.AppManager[^)]*\)'
45-45: Consider the implications of changingappfield to value type.The
appfield type has been changed from a pointer (*appmanager.AppManager[T]) to a value type (appmanager.AppManager[T]). This change may have several implications:
- Performance: If
AppManageris a large struct, this could lead to increased memory usage and potential performance impacts when theConsensusstruct is copied.- Behavior: This change ensures that
appis always initialized, potentially preventing nil pointer dereferences. However, it may also change how theappfield is used throughout the codebase.- Mutability: With a value type, any modifications to
appwill be local to the method unless the field is reassigned.Please ensure that this change is intentional and that all usages of
appthroughout the codebase have been updated accordingly.✅ Verification successful
Verification Successful: No remaining pointer usages of
AppManagerfound.🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash # Check for any remaining pointer usages of AppManager in the codebase rg --type go 'app\s+\*appmanager\.AppManager'Length of output: 67
Script:
#!/bin/bash # Re-check for any remaining pointer usages of AppManager in the codebase with the correct pattern rg --type go 'app\s+\*appmanager\.AppManager'Length of output: 47

649-664: Initialization of 'stf' instance is correctly updatedThe
stf.Newfunction is now called directly with the appropriate parameters, and error handling is properly implemented usingrequire.NoError(t, err). This change simplifies the code and aligns with best practices.
675-687: Simplification of 'appmanager' initialization enhances readabilityThe direct initialization of
appmanager.Newwith the necessary parameters removes the previous builder pattern, leading to clearer and more maintainable code. The configuration and dependencies are correctly set up, and error handling is appropriately managed.

60-60: Improved method naming: Omitted 'Get' prefixThe method
GetQueryHandlers()has been renamed toQueryHandlers(), which aligns with Go conventions by omitting the 'Get' prefix in accessor methods. According to the Uber Go Style Guide, getter methods should avoid using the 'Get' prefix unless necessary for disambiguation. This change enhances code readability and consistency.
88-88: Type change inQuerymethod may affect implementationsThe
Querymethod'smsgparameter type has changed fromgogoproto.Messagetotransaction.Msg. This narrows the accepted message types and may impact existing implementations that rely on the broadergogoproto.Messageinterface. Ensure that all implementations of theQuerymethod are updated to accommodate this change and that no required functionality is lost.To confirm that all implementations have been updated, you can run the following script:
This script searches for all
Querymethod implementations and displays their signatures, helping you verify that they now usetransaction.Msgas themsgparameter.✅ Verification successful

if this is moved to cometbft we drop the dependency from cometbft on appamanger. This follows the design in which appmanager does not depend on stf as well
Description
Simplify runtime/v2 and appmanager by removing builder for consistency.
