Pull Request Overview
This PR refactors ETag generation for GZIP files to read the CRC32 checksum directly from the GZIP file trailer instead of requiring a separate byte array parameter. The refactor centralizes file operations within the _getEtag function and adds proper error handling while maintaining the same ETag format.
Key changes:
- Modified
_getEtag()function signature to accept a File handle and return boolean success status - Consolidated GZIP trailer reading logic into the
_getEtagfunction with error handling - Updated calling code to use the new function signature and handle return status
