1203-1204: Refactor: Delegate to CreateQueryContextWithCheckHeader.

The CreateQueryContext function now delegates to CreateQueryContextWithCheckHeader with an additional checkHeader argument set to true. This refactor is correct and aligns with the new logic introduced.


1206-1208: Function Documentation: Ensure Clarity.

The function documentation clearly describes the purpose and parameters of CreateQueryContextWithCheckHeader. This is a good practice.


Line range hint 1209-1213:
Error Handling: Check for Negative Height.

The function correctly checks for a negative height and returns an appropriate error. This is a good practice for input validation.


Line range hint 1214-1216:
Use Custom Query Multi-Store if Provided.

The function uses a custom query multi-store if provided, otherwise defaults to the commit multi-store. This adds flexibility to the function.


Line range hint 1217-1224:
Error Handling: Validate Height Against Latest Version.

The function validates the provided height against the latest version of the multi-store, ensuring that queries are not made for future heights. This is a good practice.


Line range hint 1225-1231:
Error Handling: Validate Proof for Heights <= 1.

The function correctly handles the case where proof is requested for heights less than or equal to 1, which is invalid.


Line range hint 1232-1240:
Cache Multi-Store with Version: Error Handling.

The function attempts to cache the multi-store with the specified version and handles errors appropriately. This ensures that the state at the specified height is correctly loaded.


1254-1267: Header Validation: Loop Through States.

The function loops through the available states (checkState and finalizeBlockState) to find a valid block header. This ensures that the correct header is used for the query context.


1269-1275: Error Handling: No Valid Header Found.

The function returns an error if no valid header is found in the available states. This ensures that the query context is only created with a valid header.


1276-1284: Create Query Context: Set Context Parameters.

The function sets various parameters in the context, including gas meter, header info, and block height. This ensures that the context is correctly configured for the query.

I was trying to use block timestamp as random seed for smart contract. Currently a query result of new block height may be returned with the previous block timestamp if the block is committed but state not being set.@facundomedica you can see the case in TestABCI_CreateQueryContext_Before_Set_CheckState.

Line range hint 142-146:
Ensure the correctness of the new function usage.

The Info function now uses CreateQueryContextWithCheckHeader. Verify that this change aligns with the intended logic and that the checkHeader parameter is correctly set to false.


1203-1204: Delegation to new function looks good.

The CreateQueryContext function correctly delegates to CreateQueryContextWithCheckHeader with the checkHeader parameter set to true.


1208-1209: Check for negative height.

The function starts by checking for negative height values, which is a good practice to ensure valid input.


1240-1244: Iterate over state contexts to determine the appropriate header.

The loop iterates over various state contexts to determine the appropriate header. This enhances the robustness of the context creation process.


1258-1264: Handle missing header scenario.

The function handles the scenario where the header is not found in any state context, returning an explicit error. This improves error handling.


1270-1280: Deferred function for setting header info.

The deferred function ensures that the header info is set correctly after the main logic executes, which is a good practice for maintaining context integrity.


1292-1299: Create new context with appropriate settings.

The function creates a new context with the appropriate settings, including gas meter and header info. This ensures that the context is correctly initialized for queries.


Line range hint 1197-1199:
Verify the function usage.

The handleQueryGRPC function calls CreateQueryContext, which now delegates to CreateQueryContextWithCheckHeader. Ensure that this change aligns with the intended logic.

CHANGELOG.md (1)

The changes to UnbondingDelegation in the v0.47.0 release of the Cosmos SDK introduce significant updates to the staking module, particularly in relation to unbonding delegations. Here are the key points:

  1. New functionality: A new message type, MsgCancelUnbondingDelegation, has been introduced. This allows delegators to cancel an ongoing unbonding delegation, which is a significant new feature in the staking module.

  2. Query improvements: There are numerous new or updated query functions related to UnbondingDelegation, such as ValidatorUnbondingDelegations, DelegatorUnbondingDelegations, and UnbondingDelegation. This suggests improved capabilities for querying unbonding delegation information.

  3. Breaking changes: The CHANGELOG.md file explicitly mentions both API Breaking Changes and State Breaking changes. This indicates that there are significant changes that may affect existing implementations and potentially the state of the blockchain.

  4. Potential structural changes: While we couldn't directly observe the UnbondingDelegation structure, the presence of many related functions suggests that there might be changes to how unbonding delegations are handled internally.

Developers working with the staking module, particularly those dealing with unbonding delegations, should carefully review these changes. The new cancellation feature and updated querying capabilities may require updates to existing implementations. Additionally, the mention of breaking changes in the changelog emphasizes the need for thorough testing and potentially migration strategies when upgrading to this version.

770-784: Improve test naming for better clarity in subtests

In TestABCI_CreateQueryContextWithCheckHeader, the subtests use the constant name "valid height with different initial height" in t.Run. This can make it difficult to identify which specific test case fails during execution. To enhance clarity, consider adding a name field to your test cases and using it in t.Run, so that each subtest is uniquely identified.

Apply this diff to improve subtest naming:

 testCases := []struct {
-	checkHeader bool
-	expErr      bool
+	name        string
+	checkHeader bool
+	expErr      bool
 }{
-	{true, true},
-	{false, false},
+	{"checkHeader true, expect error", true, true},
+	{"checkHeader false, expect no error", false, false},
 }
 
 for _, tc := range testCases {
-	t.Run("valid height with different initial height", func(t *testing.T) {
+	t.Run(tc.name, func(t *testing.T) {
baseapp/abci.go (1)

1212-1214: Add detailed documentation for the checkHeader parameter.

The new function CreateQueryContextWithCheckHeader introduces a checkHeader boolean parameter. Providing more detailed comments or examples on when to set checkHeader to true or false would improve code readability and help other developers understand the intended usage.

787-829: Questioning the order of InitChain after block commitments

In TestABCI_CreateQueryContext_Before_Set_CheckState, the call to InitChain is made after finalizing and committing blocks. Typically, InitChain is called before processing any blocks to initialize the application state. Verify whether calling InitChain after committing blocks is intentional and necessary for this test scenario, as it may not reflect the actual initialization sequence in production.


756-785: Unit tests adequately cover new functionality

The newly added test TestABCI_CreateQueryContextWithCheckHeader effectively tests the behavior of CreateQueryContextWithCheckHeader with different checkHeader values. The test ensures that when checkHeader is true, an error is expected, and when false, no error occurs and the block height is correctly set. This enhances the test coverage for the new functionality introduced.

baseapp/abci.go (2)

145-145: Verify the implications of disabling header checks in CreateQueryContextWithCheckHeader.

In the Info method, CreateQueryContextWithCheckHeader is called with checkHeader set to false. Please ensure that bypassing the header check here does not introduce any security vulnerabilities or inconsistent state, especially when retrieving the application version.


1209-1210: Ensure consistent behavior when checkHeader is set to true.

The CreateQueryContext method now calls CreateQueryContextWithCheckHeader with checkHeader set to true. Please verify that this change maintains the intended behavior across all uses of CreateQueryContext, and that header checks are performed correctly.

⚠️ Potential issue

Inconsistent method receiver types in mockABCIListener methods

The methods ListenFinalizeBlock and ListenCommit of mockABCIListener use different receiver types: ListenFinalizeBlock uses a value receiver (m mockABCIListener), whereas ListenCommit uses a pointer receiver (m *mockABCIListener). According to Go best practices and the Uber Go Style Guide, methods on the same type should have consistent receiver types to avoid confusion and potential bugs. Consider changing ListenFinalizeBlock to use a pointer receiver for consistency.

Apply this diff to fix the inconsistent receiver:

-func (m mockABCIListener) ListenFinalizeBlock(_ context.Context, _ abci.FinalizeBlockRequest, _ abci.FinalizeBlockResponse) error {
+func (m *mockABCIListener) ListenFinalizeBlock(_ context.Context, _ abci.FinalizeBlockRequest, _ abci.FinalizeBlockResponse) error {

⚠️ Potential issue

Handle errors when retrieving commit info for historical queries.

At lines 1295-1298, when attempting to retrieve the commit info to get the timestamp for historical queries, the code assumes GetCommitInfo succeeds if err == nil and cInfo != nil. However, it's possible for GetCommitInfo to return an error or nil cInfo. Ensure that errors are properly handled, and default values are used if necessary.

Apply this diff to handle potential errors:

 if !isLatest {
     rms, ok := app.cms.(*rootmulti.Store)
     if ok {
         cInfo, err := rms.GetCommitInfo(height)
-        if cInfo != nil && err == nil {
+        if err != nil {
+            return ctx, errorsmod.Wrapf(err, "failed to get commit info for height %d", height)
+        }
+        if cInfo != nil {
             ctx = ctx.WithHeaderInfo(coreheader.Info{Height: height, Time: cInfo.Timestamp})
+        } else {
+            ctx = ctx.WithHeaderInfo(coreheader.Info{Height: height})
+        }
     }
 }

⚠️ Potential issue

Ensure header is properly assigned to prevent nil dereference.

In the loop starting at line 1246, if neither app.checkState nor app.finalizeBlockState is non-nil or meet the conditions, header may remain nil, potentially leading to a nil pointer dereference later in the code. Please ensure that header is always assigned a valid value or add error handling for the case when it remains nil.

Apply this diff to add a check for header being nil:

     }

+    if header == nil {
+        return sdk.Context{},
+            errorsmod.Wrapf(
+                sdkerrors.ErrInvalidHeight,
+                "failed to retrieve header for height %d", height,
+            )
+    }

     // when a client did not provide a query height, manually inject the latest
