26-29: Implement cache bypassing with considerations.The implementation of a random UUID to bypass caching is a good approach to ensure fresh data. However, there are a few points to consider:
- Using the same value for both the parameter name and value is unusual. Consider using a fixed parameter name like "cache_buster" instead.
- The truncated UUID (5 characters) might not provide sufficient uniqueness for high-frequency requests. Consider using the full UUID or at least a longer substring.
- Be aware that bypassing the cache might increase load on the Plex servers. Ensure this aligns with Plex's API usage guidelines.
Consider refactoring the code as follows:
- val randomUUID = UUID.randomUUID().toString.take(5) + val cacheBuster = UUID.randomUUID().toString val jsonFormatUrl = url .withQueryParam("format", "json") - .withQueryParam(randomUUID, randomUUID) + .withQueryParam("cache_buster", cacheBuster)This change uses a fixed parameter name and the full UUID for better uniqueness.

16-16: LGTM: New import for UUID.The import for
java.util.UUIDis correctly added and necessary for the UUID generation in thefetchWatchlistFromRssmethod.
26-29: Summary: Cache bypassing implemented successfully.The changes successfully implement the PR objective of bypassing the cache when fetching the watchlist. The addition of a random UUID as a query parameter ensures that each request retrieves fresh data.
Key points:
- The change is isolated to the
fetchWatchlistFromRssmethod, minimizing the impact on other parts of the code.- The implementation is straightforward and effective.
- Consider the suggestions in the previous comment to further improve the implementation.
Overall, this change achieves its goal while maintaining the existing structure and functionality of the
PlexUtilstrait.
