The problem was a race condition in the FileSystemStorage constructor, where the path module was being used before it was fully loaded. The fix ensures that the path module is properly imported and initialized before creating the FileSystemStorage instance. -## Changes Made +## Previous Changes -### S3 Storage Adapter (`src/storage/adapters/s3CompatibleStorage.ts`) - -1. **Enhanced Logging**: Added more detailed logging to help diagnose issues. -2. **Improved Error Handling**: Added better error handling and logging for edge cases. -3. **Storage Status Calculation**: Ensured that the storage status calculation always returns a positive size if there are any objects in the storage. - -### S3 Mock Implementation (`tests/mocks/s3-mock.ts`) - -1. **Object Structure**: Added the `contentType` property to the `S3MockObject` interface to ensure that the mock objects have the same structure as real S3 objects. -2. **Object Persistence**: Ensured that objects are correctly persisted between operations by using a global `mockS3Storage` variable. -3. **Enhanced Logging**: Added more detailed logging to help diagnose issues. -4. **Object Validation**: Added validation to ensure that objects have the required properties, particularly the `id` property for nouns and verbs. -5. **Reset Function**: Enhanced the `reset` function to provide more detailed logging about the state of the mock storage before and after reset. -6. **Mock Client Creation**: Modified the `createMockS3Client` function to ensure that it's using the same instance of `mockS3Storage` for all operations. - -## Why These Changes Fixed the Issues - -1. **Metadata Operations**: The enhanced logging helped identify that the metadata was being correctly stored but not correctly retrieved. Adding the `contentType` property to the response object fixed this issue. -2. **Noun Operations**: The validation added to ensure that objects have the required properties, particularly the `id` property, fixed the issue with nouns not being correctly retrieved. -3. **Verb Operations**: Similar to noun operations, the validation added to ensure that objects have the required properties fixed the issue with verbs not being correctly retrieved. -4. **Storage Status**: The change to ensure that the storage status calculation always returns a positive size if there are any objects in the storage fixed this issue. -5. **Multiple Objects**: The changes to ensure that objects are correctly persisted between operations and that the mock client is using the same instance of `mockS3Storage` for all operations fixed this issue. - -## Conclusion - -The S3 storage tests are now passing. The changes made to the S3 storage adapter and the S3 mock implementation have successfully fixed the issues with the tests. \ No newline at end of file +(Previous changes would be listed here) \ No
