x/gov/types/codec.go (2)

28-28: Ensure that MsgUpdateStore is registered with the correct interface to maintain consistency across message handling.

---

37-37: Correct registration of MsgUpdateStore with the legacy Amino codec. This ensures backward compatibility.

app/encoding_test.go (2)

37-37: Updated assertion value to 276 reflects the registration of new interfaces. Ensure this matches the actual count of registered interfaces.

---

43-43: Updated assertion value to 107 for message implementations. Validate this against the actual implementations to ensure accuracy.

Verification successful

The initial verification script indicates only 20 message implementations, which is significantly lower than the expected 107. Let's refine our approach to ensure we are accurately counting all message implementations.

---

The refined search criteria returned 0 results, suggesting it might be too restrictive. Let's broaden our search to capture all possible implementations.

---

The broader search criteria returned 52 results, which is still significantly lower than the expected 107. This discrepancy suggests that there might be other patterns or variations in how implementations are registered. Let's perform a more detailed search to capture all possible variations and contexts.

---

The detailed search confirms that there are indeed 107 message implementations, matching the updated assertion value.

• app/encoding_test.go, line 43: The assertion value of 107 for message implementations is correct.

57-57: > [!TIP]

Codebase Verification

The search results show that govMsg is a slice of strings defined and used within app/encoding_test.go. The assertion checks if the length of govMsg is 16. However, no evidence supports that govMsg actually contains 16 elements.

• app/encoding_test.go: var govMsg []string
• app/encoding_test.go: govMsg = append(govMsg, implementation)
• app/encoding_test.go: assert.Equal(t, 16, len(govMsg))

The current verification does not confirm that govMsg contains 16 elements. The count of govMsg references is only 3, not 16.

Analysis chain

Updated assertion for governance messages to 16. This should be verified against the actual messages to confirm correctness.

4-6: Consider removing the unused import encoding/hex if there are no hex operations in this file.

137-170: The methods String, KeyToBytes, OldValueToBytes, and ValueToBytes in the UpdateStore struct are well-implemented. However, use hex.DecodeString cautiously as it might throw runtime panics if not handled properly. Consider adding error handling in the String method similar to other byte conversion methods.

Walkthrough

The recent updates primarily focus on introducing a government store space functionality within the application, enhancing the store management and performing key-value updates. This includes adding new types and methods to manage store spaces, updating assertions in test cases, and enriching the proto definitions with messages and RPC methods for store updates. These changes improve the flexibility and capability of the system to handle dynamic store updates.

Poem

In code's domain where changes dwell,
A StoreSpace rises, new tales to tell.
Values shift and keys align,
Protos whisper of updates fine.
Tests now dance in structured grace,
Hail the keeper's store embrace.
Oh bytes and messages, future's spell! ⏳
