    • Now returns the licenseTermsId immediately if the license terms have already been attached to the specified IP.
    • Make sure that the SDK will not fail or duplicate actions when attempting to re-attach the same license terms.

Walkthrough

The changes in the StoryProtocolGateway contract improve the registerLicenseTerms function by adding a check to see if license terms are already attached to a specified IP address. If the terms are found to be attached, the function now returns the existing licenseTermsId without executing unnecessary operations, enhancing efficiency and streamlining the process.

Changes

File Path Change Summary
contracts/StoryProtocolGateway.sol Added a check in registerLicenseTerms to verify existing license terms for an IP before attaching.

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>.
    • 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 generate interesting stats about this repository and render them as a table.
    • @coderabbitai show all the console.log statements in this repository.
    • @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.
