x/tx/internal/testpb/signers.proto (1)

110-110: LGTM!

The addition of the empty line at the end of the file improves readability without affecting functionality. This is a good practice to follow.

x/tx/CHANGELOG.md (1)

36-39: LGTM!

The changelog entry follows the correct format, links to the relevant PR, and clearly describes the improvement. No issues found.

x/tx/signing/context.go (1)

304-308: LGTM!

The new case for handling protoreflect.BytesKind fields is implemented correctly. It retrieves the bytes from the specified field and appends them to the array of byte slices, following the existing pattern for other field types.

x/tx/internal/testpb/signers.pulsar.go (13)

Line range hint 7903-7908: ****

The change to the Signer field type from []byte to int32 in the BadSigner struct is intentional based on the PR summary. No issues with this change.

---

7925-7925: ****

The change to check if Signer is non-zero instead of checking the length of a byte slice is consistent with changing the Signer field type to int32.

---

7943-7943: ****

Setting Signer to the zero value for int32 is correct for clearing the field.

---

7962-7962: ****

Returning the int32 value of Signer is consistent with the field type change.

---

7984-7984: ****

Casting the value to int32 is correct for setting the int32 Signer field.

---

8021-8021: ****

Returning a zero int32 value is correct for initializing a new Signer field.

---

8091-8092: ****

Calculating the size contribution of the int32 Signer field is implemented correctly.

---

8123-8126: ****

Marshaling the int32 Signer field is implemented correctly using EncodeVarint.

---

8178-8181: ****

Checking the wire type and unmarshaling the int32 Signer field is implemented correctly.

---

8191-8191: ****

Decoding the int32 value into the Signer field is correct.

---

9394-9398: ****

The GetSigner method is updated to return the int32 Signer field with a default value of 0, which is correct.

---

9870-9870: ****

The Signer field is defined with the correct int32 type in the proto message.

---

9371-9371: Verify the field type change in the codebase.

Changing the Signer field type from []byte to int32 in the BadSigner message is a breaking change. Ensure that all code referencing this field has been updated to handle the new int32 type.

Tips

Chat

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  -- I pushed a fix in commit <commit_id>, please review it.
  -- Generate unit testing code for this file.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query. Examples:
  -- @coderabbitai generate unit testing code for this file.
  -- @coderabbitai modularize this function.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:
  -- @coderabbitai gather interesting stats about this repository and render them as a table. Additionally, render a pie chart showing the language distribution in the codebase.
  -- @coderabbitai read src/utils.ts and generate unit testing code.
  -- @coderabbitai read the files in the src/scheduler package and generate a class diagram using mermaid and a README in the markdown format.
  -- @coderabbitai help me debug CodeRabbit configuration file.

Note: Be mindful of the bot's finite context window. It's strongly recommended to break down tasks such as reading entire modules into smaller chunks. For a focused discussion, use review comments to chat about specific files and their changes, instead of using the PR comments.
