Hello @svenrog, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
Summary of Changes
Hello team, Gemini here to provide a summary of this pull request. Based on the title and description, the primary intent of this PR is to address a couple of issues identified in the 2.0.0 release: an attempted fix for a lazy loading issue in the Content Delivery API and a fix specifically for issues related to local blocks. The changes involve updates to the changelog, minor code cleanup, refactoring of internal link data handling, and improvements to the lazy loading mechanism for link collections.
Highlights
- Bug Fixes: This PR includes fixes aimed at resolving a lazy loading issue within the Content Delivery API and addressing problems encountered with local blocks in the
2.0.0version. - Lazy Loading Thread Safety: Improved the thread safety of the lazy loading mechanism in
PropertyLinkDataCollectionby introducing a lock (_lazyLock) around the data loading logic in theValuegetter. - Internal LinkData Refactoring: Refactored the internal
LinkDataclass by changingIDictionaryfields toDictionary, removing an unused_pessimisticLock, and simplifying theGetAttributeKeymethod by removing the lock and usingTryAdd. - Serialization Control: Added
[SystemTextJsonIgnore]and[NewtonsoftJsonIgnore]attributes to theAttributesandIsReadOnlyproperties inLinkDatato prevent these internal properties from being serialized, likely for API responses. - Collection Interface Change: Changed
LinkDataCollection<TLinkData>to implementIList<TLinkData>in addition toIEnumerable<TLinkData>, providing more list-specific functionality.

Code Review
The pull request introduces several changes to the Geta.Optimizely.GenericLinks library, including fixes for lazy loading and local blocks. The changes touch various parts of the codebase, including data models, collections, and property handling. Overall, the changes seem reasonable, but there are a few areas that could be improved for clarity and efficiency.
Summary of Findings
- Thread Safety: The removal of the lock in
LinkData.csand the introduction ofTryAddraises concerns about thread safety. WhileTryAddis thread-safe, ensure that all other operations within theGetAttributeKeymethod are also thread-safe. The introduction of_lazyLockinPropertyLinkDataCollection.csalso needs scrutiny to ensure that the lazy loading mechanism is thread-safe and doesn't introduce any race conditions. - Lazy Loading: The lazy loading implementation in
PropertyLinkDataCollection.csuses a lock to ensure thread safety. Ensure that theLoadDatamethod is thread-safe and doesn't have any potential race conditions, as this is a critical section. - Documentation: Consider adding more documentation to explain the purpose of the changes, especially the removal of the lock in
LinkData.csand the lazy loading implementation inPropertyLinkDataCollection.cs. This will help future developers understand the changes and avoid potential issues.
Merge Readiness
The pull request introduces important fixes for lazy loading and local blocks. However, the thread safety concerns and the lack of documentation in certain areas need to be addressed before merging. I recommend addressing these issues before merging. I am unable to approve this pull request, and other reviewers should review and approve this code before merging.
