* fix: Fixes https://github.com/BerriAI/litellm/issues/23185
* fix(responses/main.py): ensure litellm metadata custom cost works
* refactor: move all logging updates to a common function, to have just 1 place to update logging kwarg updates
* [Docs] Enable local file support
Implemented internal handling for converting file-type documents to the required format for OCR processing, ensuring seamless integration with various providers.
* Refactor OCR file handling and improve security checks
Removed deprecated MIME type mapping and file conversion functions, replacing them with updated implementations. Enhanced security by rejecting 'file' document types in JSON requests, ensuring file uploads are handled via multipart/form-data. Updated tests to reflect these changes and ensure proper functionality.
* Enhance MIME type validation in OCR processing
Added a regular expression check to validate MIME types in the convert_file_document_to_url_document function, raising a ValueError for invalid types. Updated tests to ensure proper error handling for unsupported MIME types.
* Enhance type safety in OCR file handling
Added type casting for the uploaded file in the _parse_multipart_form function to ensure proper handling of UploadFile instances. This change improves type safety and reduces potential runtime errors during file processing.
* Refactor MIME type handling in document uploads
Updated the MIME type extraction logic to strip parameters from the Content-Type header, ensuring only the base type is used. Added tests to verify that MIME parameters are correctly handled and stripped in various scenarios.
* Update OCR documentation for MIME type recommendations and remove unnecessary tips
Clarified the recommended usage of MIME types for raw bytes in document uploads. Simplified the documentation by removing the tip about multipart file uploads from tools like Postman, ensuring a more concise and focused guide.
* Enhance multipart form handling in OCR endpoints
Updated the _parse_multipart_form function to ignore both 'file' and 'document' fields during form parsing, ensuring that the document built from the uploaded file is not overridden. Added a new test to verify that injected document fields do not affect the constructed document, improving security and robustness of the file upload process.
