🔍 Code Quality and Best Practices

LeaderboardEntriesManager.cs (FindInsertPosition):

• Binary search implementation could use more descriptive variable names (mid could be midIndex)
• Consider extracting the comparison logic to improve readability

ChannelStorageManager.cs (ListProps):

• Potential infinite recursion: ListProps calls ListStorageProps which may call back to ListProps if bustCache=false
• The async method doesn't await the recursive call properly

🐛 Potential Bugs or Issues

DateTime Parsing Risk (LeaderboardEntriesManager.cs:81):

• DateTime.Parse(a.createdAt) lacks error handling and culture specification
• Could throw exceptions with malformed date strings
• Consider using DateTime.TryParseExact with specific format

Null Reference Vulnerabilities:

• ChannelStoragePropsListResponse.props field lacks null safety checks
• LeaderboardEntry.createdAt could be null when comparing entries

Array Return Pattern:

• return new ChannelStorageProp[0] should use Array.Empty() for better performance

⚡ Performance Considerations

Memory Allocation:

• keysToFetch.ToArray() creates unnecessary array copy in ListProps
• String concatenation in query building could use StringBuilder for larger arrays

Caching Strategy:

• Mixed caching approach in ListProps could lead to inconsistent states
• Consider consolidating cache management patterns

Binary Search Efficiency:

• While binary search is good, the CompareEntries method does DateTime parsing on every comparison
• Consider pre-parsing dates or caching parsed values

🔒 Security Concerns

Input Validation:

• No validation on propKeys array length in URL construction
• Query parameter injection possible if prop keys contain special characters
• Missing URL encoding for prop key values

🔄 Backwards Compatibility

API Changes:

• New LeaderboardSortMode enum and properties added to LeaderboardEntry are additive (good)
• New query parameters in GetEntriesOptions are optional with defaults (safe)
• New ListStorageProps method doesn't break existing functionality

Data Contract:

• Adding createdAt, leaderboardName, etc. to LeaderboardEntry won't break existing serialization due to Unity's JsonUtility handling missing fields gracefully

🔍 Code Review - Release 0.47.0

🐛 Potential Bugs or Issues

ChannelStorageManager.cs:66 - Recursive API call issue:

• ListProps method calls Talo.Channels.ListStorageProps with bustCache = true, which could lead to infinite recursion since it's the same method being called from ChannelsAPI
• Consider adding a flag parameter or restructuring to prevent circular calls

LeaderboardEntriesManager.cs:87 - DateTime parsing without error handling:

• DateTime.Parse(a.createdAt) could throw exceptions for invalid date formats
• Consider using DateTime.TryParse or DateTime.ParseExact with proper error handling

⚡ Performance Considerations

LeaderboardEntriesManager.cs:25 - O(n) removal operation:

• RemoveAll((e) => e.id == entry.id) performs linear search on every upsert
• Consider using a Dictionary or HashSet for faster lookups when dealing with large entry collections

ChannelsAPI.cs:361 - String concatenation in query building:

• Using string.Join for query parameters is fine, but the ternary operator creates unnecessary string allocations
• Consider using StringBuilder for larger parameter sets

🔒 Security Concerns

ChannelsAPI.cs:365 - Query parameter injection:

• propKeys array values are directly concatenated into the query string without URL encoding
• Use Uri.EscapeDataString() to properly encode parameter values to prevent injection attacks

LeaderboardsAPI.cs:26 - URL parameter encoding:

• Similar issue with propKey, propValue, startDate, and endDate parameters not being URL encoded
• All user-provided values should be properly escaped

🔄 Backwards Compatibility

LeaderboardEntry.cs:25 - Property access change:

• New LeaderboardSortMode property with case-sensitive string comparison might break existing code that expects different casing
• Consider making the comparison more robust or documenting the expected format

ChannelsAPI.cs:351 - New method signature:

• ListStorageProps method adds new functionality but the internal caching behavior change might affect existing usage patterns
• Ensure existing code calling channel storage methods still behaves as expected

💡 Code Quality & Best Practices

LeaderboardEntriesManager.cs:44 - Binary search implementation:

• Good use of binary search for insertion, but the comparison logic is complex
• Consider extracting the comparison logic into a separate IComparer<LeaderboardEntry> implementation for better testability and readability

Test Coverage:

• Excellent addition of comprehensive unit tests for the leaderboard entries manager
• Tests cover edge cases well, including equal scores and different sort modes
