# Description of Changes This pull request introduces major improvements to the PDF attachment API, adding new endpoints for listing, renaming, and deleting attachments in PDFs, as well as improving error handling and content negotiation. It also adds support for converting PDFs to PDF/A-3b format when adding attachments and introduces stricter validation for attachment uploads. The exception handling is improved to ensure consistent JSON error responses, even when the client requests a PDF. **API Feature Additions:** * Added new endpoints in `AttachmentController` for listing (`/list-attachments`), renaming (`/rename-attachment`), and deleting (`/delete-attachment`) PDF attachments, with corresponding request and response models: `ListAttachmentsRequest`, `RenameAttachmentRequest`, `DeleteAttachmentRequest`, and `AttachmentInfo`. * Enhanced the `/add-attachments` endpoint to optionally convert the resulting PDF to PDF/A-3b format, controlled by a new `convertToPdfA3b` flag in `AddAttachmentRequest`. **Validation and Robustness:** * Introduced strict validation for attachment uploads, enforcing non-empty attachments, a maximum size per attachment (50 MB), and a total size limit (200 MB). **Content Negotiation:** * Updated `WebMvcConfig` to configure content negotiation, allowing both PDF and JSON responses, and preventing 406 errors when clients request PDFs but errors must be returned as JSON. <img width="370" height="997" alt="image" src="https://github.com/user-attachments/assets/571504d4-e97e-4b30-ae97-3defba217b47" /> <img width="1415" height="649" alt="image" src="https://github.com/user-attachments/assets/bb8863fc-0be8-4bf2-af7d-73a229010f9a" /> <img width="1415" height="649" alt="image" src="https://github.com/user-attachments/assets/68092672-5be5-4ef7-9cbc-1fb008b728e1" /> <img width="1415" height="649" alt="image" src="https://github.com/user-attachments/assets/c4b0eda5-2573-4e38-8284-c077acb83f7f" /> <!-- Please provide a summary of the changes, including: - What was changed - Why the change was made - Any challenges encountered Closes #(issue_number) --> --- ## Checklist ### General - [X] I have read the [Contribution Guidelines](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/CONTRIBUTING.md) - [X] I have read the [Stirling-PDF Developer Guide](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/DeveloperGuide.md) (if applicable) - [ ] I have read the [How to add new languages to Stirling-PDF](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/HowToAddNewLanguage.md) (if applicable) - [X] I have performed a self-review of my own code - [X] My changes generate no new warnings ### Documentation - [ ] I have updated relevant docs on [Stirling-PDF's doc repo](https://github.com/Stirling-Tools/Stirling-Tools.github.io/blob/main/docs/) (if functionality has heavily changed) - [ ] I have read the section [Add New Translation Tags](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/devGuide/HowToAddNewLanguage.md#add-new-translation-tags) (for new translation tags only) ### Translations (if applicable) - [ ] I ran [`scripts/counter_translation.py`](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/docs/counter_translation.md) ### UI Changes (if applicable) - [X] Screenshots or videos demonstrating the UI changes are attached (e.g., as comments or direct attachments in the PR) ### Testing (if applicable) - [X] I have tested my changes locally.
