105-106: Enhance error message with expected input formats.The current error message could be more helpful by specifying the accepted upload methods.
- return {"message": "No valid source provided"}, 400 + return { + "message": "No valid source provided", + "accepted_formats": { + "file_upload": "multipart/form-data with 'file' field", + "json_upload": { + "source": "string", + "source_type": "string (url|file)" + } + } + }, 400
88-107: Consider adding rate limiting and async processing.For a production-ready upload endpoint, consider implementing:
- Rate limiting to prevent abuse
- Async processing for large files using a task queue (e.g., Celery)
- Progress tracking for large uploads
- Chunked upload support for better reliability
Would you like help implementing any of these architectural improvements?

Several improvements needed for robust file upload handling
While the basic implementation works, there are several areas that need attention for production-ready file upload handling:
- Add validation and security measures:
- File size limits
- File type validation
- Memory usage optimization for large files
- Enhance error handling
- Improve request handling
- Add proper resource management
Here's a suggested improvement:
elif source_type == "file":
upload_url_data = self.conn.get(
path=f"/collection/{self.collection.id}/upload_url",
params={"name": name},
)
upload_url = upload_url_data.get("upload_url")
- files = {"file": (name, source)}
- response = requests.post(upload_url, files=files)
- response.raise_for_status()
- upload_args["url"] = upload_url
+ try:
+ # Validate file size
+ if hasattr(source, 'seek') and hasattr(source, 'tell'):
+ source.seek(0, os.SEEK_END)
+ size = source.tell()
+ source.seek(0)
+ if size > MAX_UPLOAD_SIZE: # Define this constant
+ raise ValueError(f"File size exceeds maximum limit of {MAX_UPLOAD_SIZE} bytes")
+
+ # Stream the file in chunks to avoid memory issues
+ with source:
+ files = {"file": (name, source)}
+ response = requests.post(
+ upload_url,
+ files=files,
+ timeout=300, # 5 minutes timeout
+ headers={"Accept": "application/json"}
+ )
+ response.raise_for_status()
+ upload_args["url"] = upload_url
+ except requests.exceptions.RequestException as e:
+ raise ValueError(f"Failed to upload file: {str(e)}")Let's verify the maximum file size handling in the codebase:
Consider implementing the following architectural improvements:
- Move file validation logic to a separate utility function
- Add retry logic for failed uploads
- Consider using multipart uploads for large files
- Add progress tracking for large uploads
- Implement proper cleanup of temporary upload URLs on failure
Would you like me to provide implementations for any of these improvements?

Add validation for JSON source uploads.
The current implementation lacks validation for JSON payload:
- Missing validation for source_type values
- No validation of source format/content
- Potential KeyError if source_type is missing
Apply these improvements:
elif "source" in request.json:
source = request.json["source"]
+ if not source:
+ return {"message": "Empty source provided"}, 400
+
+ if "source_type" not in request.json:
+ return {"message": "source_type is required"}, 400
source_type = request.json["source_type"]
+
+ # Validate source_type
+ valid_source_types = ["url", "file"] # Add other valid types
+ if source_type not in valid_source_types:
+ return {"message": f"Invalid source_type. Must be one of: {', '.join(valid_source_types)}"}, 400
+
+ # Validate source format based on source_type
+ if source_type == "url" and not source.startswith(("http://", "https://")):
+ return {"message": "Invalid URL format"}, 400
+

97-111:
Add file upload validations and improve memory handling.
Previous review comments about file validation remain relevant. Additionally, reading the entire file into memory could cause issues with large files.
Consider using chunked upload for large files:
if "file" in request.files:
file = request.files["file"]
- file_bytes = file.read()
+ # Stream file in chunks instead of loading entirely into memory
+ chunk_size = 8192 # 8KB chunks
+ file_chunks = []
+ while True:
+ chunk = file.read(chunk_size)
+ if not chunk:
+ break
+ file_chunks.append(chunk)
safe_filename = secure_filename(file.filename)112-115:
Add validation for JSON source uploads.
The JSON source handling lacks validation for required fields and source_type values.
Previous review suggestions for JSON validation should be implemented to prevent potential KeyError exceptions and invalid source types.
106-111: Verify VideoDBHandler.upload implementation.
Need to verify the implementation of VideoDBHandler.upload() method to ensure proper handling of different source types and error cases.
Also applies to: 114-115
✅ Verification successful
VideoDBHandler.upload implementation is properly structured and handles different source types
The implementation shows a well-structured flow for handling uploads:
- The handler delegates to VideoDBTool which properly handles both URL and file-based uploads
- File uploads use a secure upload URL obtained from the API
- The code includes proper error handling with try-catch in the route
- Secure filename validation is implemented
- Different media types and source types are supported with proper parameter passing

Validate collection existence before processing upload.
The code should verify that the collection exists before attempting to upload.
Add collection validation:

🛠️ Refactor suggestion
Implement media type validation using the SUPPORTED_MEDIA_TYPES constant.
The SUPPORTED_MEDIA_TYPES constant is defined but not utilized. This should be used to implement the TODO comment on line 104 for media type validation.
Here's how to implement the validation:
media_type = file.content_type.split("/")[0]
+ if file.content_type not in SUPPORTED_MEDIA_TYPES:
+ return {"message": f"Unsupported media type. Supported types are: {', '.join(SUPPORTED_MEDIA_TYPES)}"}, 400
- # TODO: Check if the media type is supported, if not, return 400
return videodb.upload(Committable suggestion skipped: line range outside the PR's diff.

let the internal function of conn.upload handle the validation, if it not a valid type, the function should throw error, we are going to catch the error and simply pass that to client.

@0xrohitgarg, understood. If the conn.upload function handles the media type validation and raises an error for unsupported types, and you're catching the exception and passing it to the client, that approach works well.

Learning: In `backend/director/entrypoint/api/routes.py`, the `upload_video` function relies on `conn.upload` for media type validation. The `conn.upload` function in `backend/director/tools/videodb_tool.py` raises an error if the media type is unsupported, and exceptions are caught and passed to the client in `upload_video`.
Note: Learnings are effective only in the context of similar code segments. To apply general coding guidelines, please configure review instructions. You can manage existing learnings in the app.

4-4: LGTM: Good security practice using secure_filename
The addition of secure_filename from werkzeug.utils is appropriate for sanitizing uploaded filenames.
92-93:
Add collection validation before processing upload
The upload process should verify that the collection exists before attempting any operations.
Add collection validation at the start:
try:
videodb = VideoDBHandler(collection_id)
+ if not videodb.get_collection():
+ return {"message": "Collection not found"}, 40495-108:
Enhance file upload security and validation
The file upload handling needs additional security measures:
- File size limits
- Media type validation
- Memory-efficient file handling
Add these safety checks:
if "file" in request.files:
file = request.files["file"]
+ if not file or not file.filename:
+ return {"message": "No file provided"}, 400
+
+ # Check file size before reading
+ file.seek(0, os.SEEK_END)
+ size = file.tell()
+ file.seek(0)
+ if size > app.config.get("MAX_CONTENT_LENGTH", 16 * 1024 * 1024):
+ return {"message": "File too large"}, 413
+
+ # Validate media type
+ if file.content_type not in app.config.get("SUPPORTED_MEDIA_TYPES", ["video/mp4"]):
+ return {"message": "Unsupported media type"}, 400
+
file_bytes = file.read()109-112:
Add validation for source-based uploads
The source upload handling lacks necessary validation and error handling.
Add validation for source-based uploads:
elif "source" in request.json:
+ if not request.json.get("source"):
+ return {"message": "Empty source provided"}, 400
+
+ if "source_type" not in request.json:
+ return {"message": "source_type is required"}, 400
