How do rate limits work?CodeRabbit enforces hourly rate limits for each developer per organization. WalkthroughThe recent modifications enhance the functionality related to S3 bucket management and file copying operations. Specifically, they ensure that all objects within an S3 bucket are deleted before the bucket itself is removed, and improve the copying process by refining how local and S3 targets are handled. This includes better struct organization, method refactoring, and improved testing for robustness and reliability in file management tasks. Changes

- 133-142: The method
copyTargetsInLocalusesfile.WalkDirto list files when the source is a directory. Ensure thatfile.WalkDircorrectly handles symbolic links and does not follow them, to prevent potential security issues or unintended behavior.Verification successful
The implementation of
WalkDirinutils/file/file.gousesfilepath.WalkDirfrom the Go standard library, which iterates over each entry in a directory. The function checks if an entry is a directory and skips it if true, appending only file paths to thefilesslice. This implementation does not explicitly handle symbolic links, relying on the behavior offilepath.WalkDir.The Go documentation for
filepath.WalkDirstates that it does not follow symbolic links unless the link is to a directory and the function is called directly on that link. SinceWalkDirdoes not explicitly follow symbolic links and only appends file paths (excluding directories), it inherently does not follow symbolic links to files. However, if a symbolic link points to a directory andWalkDiris called on that directory, the behavior would follow the standardfilepath.WalkDirbehavior, which includes traversing into symbolic links that point to directories.Given this, the original concern about
file.WalkDirpotentially following symbolic links and leading to security issues or unintended behavior is addressed by the inherent behavior offilepath.WalkDir. It does not follow symbolic links to files, and its handling of symbolic links to directories is consistent with the documented behavior of the Go standard library.Scripts Executed

The implementation of DeleteAllS3BucketDelete now includes deleting all objects within an S3 bucket before attempting to delete the bucket itself. This change addresses potential issues with deleting non-empty buckets. However, it's important to handle pagination in the ListObjects call to ensure all objects are deleted, especially in buckets with a large number of objects.
+ // Ensure to handle pagination for buckets with many objects
+ var continuationToken *string = nil
+ for {
+ output, err := client.ListObjects(ctx, &s3.ListObjectsInput{
+ Bucket: bucket.Name,
+ ContinuationToken: continuationToken,
+ })
+ if err != nil {
+ t.Fatal(err)
+ }
+ for _, object := range output.Contents {
+ _, err := client.DeleteObject(ctx, &s3.DeleteObjectInput{
+ Bucket: bucket.Name,
+ Key: object.Key,
+ })
+ if err != nil {
+ t.Fatal(err)
+ }
+ }
+ if !output.IsTruncated {
+ break
+ }

DeleteAllS3BucketDelete() method only used for unit test. So, there is no many s3 objects. We don't use pagination when execute unit test.

@nao1215, understood! Given that DeleteAllS3BucketDelete is used solely for unit testing with a limited number of objects, your approach makes sense. Skipping pagination under these conditions seems reasonable. Thank you for clarifying the context and usage of this method. If there's anything else you need, feel free to ask!

- 232-237: The
Splitmethod now cleans theS3Keyusingfilepath.Cleanbefore returning it. This is a good practice to ensure theS3Keyis in a standard format, especially when dealing with file paths that might include relative components like...app/domain/model/s3_test.go (1)
- 662-673: The new test cases added to
TestBucket_Spliteffectively cover scenarios with multiple levels in the bucket path and include parent directory references. These additions enhance the test coverage for theSplitmethod, ensuring it behaves as expected in more complex scenarios.

- 1-7: The package and import declarations are correctly structured, ensuring that the mock implementation is properly isolated within the
mockpackage and has access to necessary types from theusecasepackage.- 9-10: The
S3ObjectsListertype is declared as a function type that matches the signature of theListS3Objectsmethod in theS3ObjectListerinterface. This is a common and effective pattern for creating mocks in Go, allowing for flexible testing scenarios.- 12-15: The implementation of the
ListS3Objectsmethod correctly delegates the call to the function itself, passing through the context and input parameters. This ensures that any function assigned to an instance ofS3ObjectsListerwill be called whenListS3Objectsis invoked, allowing for dynamic behavior in tests based on the function provided. This pattern is both simple and powerful for mocking external dependencies.
