Summary of Changes
Hello @anushka567, 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!
This pull request introduces a new integration test case to validate specific behavior related to concurrent file operations on unfinalized objects. The test focuses on ensuring that the system correctly handles scenarios where a read-write file handle performs the first write, leading to an expected fallback mechanism.
Highlights
- New Integration Test: Added a new integration test,
TestFallbackHappensWhenRPlusHandleDoesFirstWrite
, tounfinalized_appends_test.go
. This test is designed to verify the system's fallback behavior when the initial write to an unfinalized object, accessed concurrently by multiple file handles, originates from anr+
(read-write) file handle.

Code Review
This pull request adds a new integration test, TestFallbackHappensWhenRPlusHandleDoesFirstWrite
, to verify a fallback mechanism for rapid appends. The test attempts to append data but uses a write operation that overwrites the file from the beginning. I've included a suggestion to correct this.
