Append Suffix to Duplicate File Names

✨ New Feature

Implemented automatic handling of duplicate filenames in attachments by appending numerical suffixes (-1, -2, etc.) before the file extension. When multiple files with the same name are uploaded, the system now automatically renames them to prevent conflicts while preserving the original file extension.

Changes

• lib/helper.js: Added handleDuplicateFilename() function that checks for existing filenames within the same parent entity and appends incremental suffixes to duplicates before insertion. The function extracts the file extension, generates a new filename with a counter, and ensures uniqueness by checking against all existing attachments.

• lib/plugin.js: Modified the CREATE handler to be asynchronous and integrated the duplicate filename handling logic. The handler now processes both single entries and arrays, applying the deduplication logic to each entry before proceeding with attachment preparation.

• tests/incidents-app/db/attachments.cds: Updated the @Validation.MaxItems annotation from 2 to 3 to accommodate testing scenarios with multiple duplicate attachments.

• tests/integration/attachments.test.js: Added comprehensive test suite with three test cases:

  • Uploading three attachments with identical names in the same draft session, verifying they are renamed to sample.pdf, sample-1.pdf, and sample-2.pdf
  • Uploading a duplicate after the first attachment has been saved, confirming proper renaming behavior across draft sessions
  • Handling edge cases where filenames already contain numerical suffixes (e.g., sample-1.pdf becomes sample-1-1.pdf, sample-1-2.pdf)

This pull request adds functionality to automatically rename duplicate attachment filenames by appending suffixes (-1, -2, etc.). I've identified several substantive issues including a logic error with extension-less files, a potential race condition with concurrent operations, a missing null check, and performance concerns with large attachment lists. The author should address these issues to ensure correct and robust handling of duplicate filenames.
