11-14: Update error message to reflect name instead of filename.

The condition has been correctly updated to check for name instead of filename. However, the error message still mentions "filename" which may cause confusion.

Please update the error message to reflect the new parameter name:

 if (!base64 || !name) {
   return res.status(400).json({
-    error: "base64 and filename is required in the request body",
+    error: "base64 and name are required in the request body",
   });
 }

1-27: Imports and global variables look good

The imports cover all necessary modules for file handling, logging, and data modeling. The use of Path for defining global file paths ensures cross-platform compatibility.

---

29-38: DocumentFile class is well-structured

The DocumentFile class is a well-defined Pydantic model that includes all necessary fields for file metadata. The use of optional fields with proper typing is a good practice.

---

255-260: File name sanitization looks good

The _sanitize_file_name function effectively replaces non-alphanumeric characters with underscores while preserving the file extension. This is a good practice for ensuring safe file names.

---

263-273: LlamaParse parser configuration looks good

The _get_llamaparse_parser function correctly loads the configuration and returns the appropriate parser based on whether LlamaParse is enabled. The implementation is clean and follows good practices.

---

1-292: Overall, the file is well-structured with room for minor improvements

The file.py module provides a comprehensive set of utilities for file handling, storage, and indexing. The code is generally well-organized and follows good practices. The suggested improvements mainly focus on enhancing error handling and ensuring cross-platform compatibility. Implementing these suggestions will make the code more robust and easier to maintain.

Key points to address:

1. Improve error handling in various methods, particularly in process_private_file, _preprocess_base64_file, and _add_file_to_llama_cloud_index.
2. Enhance the file URL construction for better cross-platform compatibility.
3. Refine the error handling and logging in the _get_available_tools function.

These changes will contribute to a more resilient and maintainable codebase.

Line range hint 62-86: LGTM! Consider a minor refactor for clarity.

The changes to the getFileContent function are well-aligned with the updated DocumentFile type. The new condition for file.url adds robustness, and the logic for constructing the default content string is more comprehensive.

However, to improve readability, consider extracting the URL content logic into a separate function. This would make the main function more concise and easier to understand.

Here's a suggested refactor:

function getUrlContent(file: DocumentFile, urlPrefix: string | undefined): string {
  if (!urlPrefix) {
    console.warn("Warning: FILESERVER_URL_PREFIX not set in environment variables. Can't use file server");
    return "";
  }
  
  if (file.url) {
    return `File URL: ${file.url}\n`;
  }
  return `File URL (instruction: do not update this file URL yourself): ${urlPrefix}/output/uploaded/${file.name}\n`;
}

function getFileContent(file: DocumentFile): string {
  let defaultContent = `=====File: ${file.name}=====\n`;
  
  const urlPrefix = process.env.FILESERVER_URL_PREFIX;
  defaultContent += getUrlContent(file, urlPrefix);

  if (file.refs) {
    defaultContent += `Document IDs: ${file.refs}\n`;
  }
  
  const sandboxFilePath = `/tmp/${file.name}`;
  defaultContent += `Sandbox file path (instruction: only use sandbox path for artifact or code interpreter tool): ${sandboxFilePath}\n`;
  
  console.log("Content: ", defaultContent);
  return defaultContent;
}

This refactoring improves the function's readability and maintainability.

---

6-12: Document the reason for including id in TypeScript but not in Python.

As noted in a previous review, there's a discrepancy between the TypeScript and Python implementations regarding the id property. It would be beneficial to document the reason for this difference, either in a comment or in the project documentation.

Consider adding a comment explaining why id is necessary in the TypeScript implementation but not in Python. This will help future developers understand the design decision and prevent confusion.

templates/types/streaming/fastapi/app/api/routers/models.py (2)

38-51: Align method types for consistency

The _get_file_content method is a @classmethod, while _get_url_llm_content is a @staticmethod. Since both methods do not modify class or instance state, consider making _get_file_content a @staticmethod for consistency and clarity.

Apply this diff to change _get_file_content to a static method:

-    @classmethod
+    @staticmethod
     def _get_file_content(cls, file: DocumentFile) -> str:

Also, update the method calls within _get_file_content:

-        url_content = cls._get_url_llm_content(file)
+        url_content = AnnotationFileData._get_url_llm_content(file)

---

Line range hint 248-256: Check for existence of files attribute in annotations

When extending uploaded_files with annotation.data.files, ensure that files is an attribute of annotation.data. Missing this check could result in an AttributeError if files is absent.

Add a check before extending uploaded_files:

                     if annotation.type == "document_file" and isinstance(
                         annotation.data, AnnotationFileData
                     ):
+                        if hasattr(annotation.data, 'files'):
                             uploaded_files.extend(annotation.data.files)

31-36: LGTM! Changes address previous review concerns.

The updated DocumentFile type effectively addresses the concerns raised in previous reviews:

1. The confusion between name and filename has been resolved by using only name.
2. The url and refs properties have been added as suggested.
3. The structure is now more concise and clear.

Additional improvements:

• The id property has been added, which is good for unique identification.
• The size property now uses number instead of string, which is more appropriate for file sizes.

These changes enhance the clarity and usability of the DocumentFile type.

templates/components/llamaindex/typescript/streaming/annotations.ts (2)

29-29: LGTM! Consistent with updated DocumentFile type.

The change in accessing file.refs directly instead of file.metadata?.refs aligns well with the updated DocumentFile type. The use of optional chaining and nullish coalescing operators ensures robust handling of potential undefined refs.

---

6-12: LGTM! Consider verifying url property usage.

The updated DocumentFile type looks good. It streamlines the structure by incorporating properties that were likely part of the removed UploadedFileMeta type. However, since url is now a required property, it's important to ensure that all places in the codebase where DocumentFile objects are created or used are updated to include this property.

To verify the url property usage, run the following script:

This script will help identify any potential issues with DocumentFile usage across the codebase.

1-27: LGTM: Imports and global variables are well-structured

The imports cover all necessary libraries and modules for file handling, logging, and data processing. The use of Path for defining global file paths ensures cross-platform compatibility.

---

29-37: LGTM: DocumentFile class is well-defined

The DocumentFile class, based on Pydantic's BaseModel, provides a clear structure for file metadata. The use of optional fields with appropriate types enhances flexibility and type safety.

---

1-291: Overall, well-structured file with room for minor improvements

The file.py module provides a comprehensive system for file handling, processing, and indexing. It demonstrates good use of type annotations, error handling, and modular design. Key strengths include:

1. Clear separation of concerns with distinct classes and functions.
2. Use of Pydantic for data validation in the DocumentFile class.
3. Comprehensive error handling in most methods.

Areas for improvement:

1. Consider moving imports that are currently inside methods to the module level where appropriate.
2. Enhance error handling in some methods, particularly in _preprocess_base64_file and _get_available_tools.
3. Improve cross-platform compatibility for file URL construction.
4. Refactor some longer methods (e.g., process_private_file) for better readability and maintainability.

Addressing these points will further enhance the robustness and maintainability of the code.

templates/types/streaming/fastapi/app/api/routers/models.py (1)

64-66: Verify existence of file.refs attribute

In _get_file_content, you're accessing file.refs without checking if the attribute exists. If refs is not a guaranteed attribute of DocumentFile, this could raise an AttributeError.

Ensure that DocumentFile includes the refs attribute. If it's optional, modify the code to safely access it:

-        if file.refs is not None:
+        if getattr(file, 'refs', None) is not None:

114-122: Improved error handling for file uploads

The addition of a try-catch block for file uploads is a good improvement in error handling. It prevents silent failures and ensures that errors during the upload process are caught and logged.

However, there are a couple of suggestions to further enhance this implementation:

1. The error message in the catch block is quite generic. Consider including more specific information about which file failed to upload. This would make debugging easier.

2. The completion log message that was previously at the end of the upload loop has been removed. Consider reinstating this or adding a similar message within the try block after the loop to maintain visibility into the upload process completion.

Here's a suggested improvement:

try {
  for (const filePath of input.sandboxFiles) {
    const fileName = path.basename(filePath);
    const localFilePath = path.join(this.uploadedFilesDir, fileName);
    const content = fs.readFileSync(localFilePath);
    await this.codeInterpreter?.files.write(filePath, content);
  }
  console.log(`Successfully uploaded ${input.sandboxFiles.length} files to sandbox`);
} catch (error) {
  console.error(`Error when uploading file to sandbox: ${error.message}`, error);
  console.error(`Failed file: ${filePath}`);
}

This change provides more detailed error logging and reinstates a completion message.

1-27: LGTM: Imports and constants are well-organized

The imports are comprehensive and well-organized. The constants for file paths are clearly defined. However, there's a minor suggestion:

Consider using Path.joinpath() instead of str(Path()) for better readability:

-PRIVATE_STORE_PATH = str(Path("output", "uploaded"))
-TOOL_STORE_PATH = str(Path("output", "tools"))
-LLAMA_CLOUD_STORE_PATH = str(Path("output", "llamacloud"))
+PRIVATE_STORE_PATH = Path("output").joinpath("uploaded")
+TOOL_STORE_PATH = Path("output").joinpath("tools")
+LLAMA_CLOUD_STORE_PATH = Path("output").joinpath("llamacloud")

---

29-42: Consider improving type hints

The DocumentFile class is well-structured. However, there's a minor improvement possible:

For the type field, consider using Optional[str] instead of str = None for better type hinting:

-    type: str = None
+    type: Optional[str] = None

This change makes it clear that the field can be None and improves type checking.

---

281-285: Add type hinting to _default_file_loaders_map function

The _default_file_loaders_map function is simple and straightforward. However, it could benefit from type hinting:

Add return type annotation to the function:

from typing import Dict, Type
from llama_index.core.readers.base import BaseReader

def _default_file_loaders_map() -> Dict[str, Type[BaseReader]]:
    default_loaders = get_file_loaders_map()
    default_loaders[".txt"] = FlatReader
    default_loaders[".csv"] = FlatReader
    return default_loaders

This change improves the function's type information, making it clearer what kind of dictionary it returns.

---

288-300: Improve type hinting in _get_available_tools function

The _get_available_tools function is well-structured with good error handling. However, it could benefit from more specific type hinting:

Update the return type annotation to be more specific:

from typing import Dict, List, Union

def _get_available_tools() -> Dict[str, List[Union[FunctionTool, Any]]]:
    # ... (rest of the function remains the same)

This change provides a more accurate type hint for the return value. The Union[FunctionTool, Any] is used because the exact type of the tools is not known (it's ignored with # type: ignore).

The error handling and logging in this function are well implemented.

16-32: Update JSON schema example to match new structure

The changes to the AnnotationFileData class correctly incorporate the DocumentFile type. However, the JSON schema example should be updated to reflect the new structure of DocumentFile.

Consider updating the JSON schema example to include all relevant fields of DocumentFile:

json_schema_extra = {
    "example": {
        "files": [
            {
                "content": "data:text/plain;base64,aGVsbG8gd29ybGQK=",

103-178: 🛠️ Refactor suggestion

⚠️ Potential issue

Improve file URL construction and error handling in save_file method

The save_file method is well-structured, but there are a few areas for improvement:

1. Use urllib.parse.urljoin for more reliable URL construction:

from urllib.parse import urljoin

file_url = urljoin(file_url_prefix, f"{save_dir}/{new_file_name}")

2. The error handling for file writing could be more specific. Consider catching OSError instead of IOError as it's more comprehensive:

except OSError as e:
    logger.error(f"OS error occurred when writing to file {file_path}: {str(e)}")
    raise

3. Consider using Path objects instead of os.path for better cross-platform compatibility:

from pathlib import Path

save_dir = Path("output") / "uploaded" if save_dir is None else Path(save_dir)
file_path = save_dir / new_file_name

4. Ensure that the FILESERVER_URL_PREFIX environment variable is set correctly in all environments where this code will run.

These changes will improve the robustness and portability of the save_file method.

233-258: ⚠️ Potential issue

Enhance error handling in _add_file_to_llama_cloud_index method

The _add_file_to_llama_cloud_index method has good error handling for the import, but could benefit from additional improvements:

1. Add error handling for the add_file_to_pipeline call:

        project_id,
        pipeline_id,
        upload_file,
        custom_metadata={},
    )
    return doc_id
except Exception as e:
    logger.error(f"Error adding file to LlamaCloud index: {str(e)}")
    raise ValueError(f"Failed to add file to LlamaCloud index: {file_name}") from e

2. Consider logging the successful addition of the file:

logger.info(f"Successfully added file {file_name} to LlamaCloud index")

3. Ensure that the LLamaCloudFileService class name is correctly spelled (note the capitalization of LLama). If it's a typo, it should be corrected to LlamaCloudFileService.

These changes will improve the robustness and observability of the _add_file_to_llama_cloud_index method.

11-11: LGTM: Import statement for DocumentFile

The import of DocumentFile from app.services.file is correctly placed and necessary for the changes in this file.

---

35-43: LGTM: Updated _get_url_llm_content method

The changes to _get_url_llm_content method are appropriate:

1. It's now a static method, which is suitable for its functionality.
2. It correctly uses the DocumentFile parameter and its url attribute.
3. The fallback URL construction is maintained for cases where file.url is None.

These changes align well with the transition to using DocumentFile.

---

68-72: LGTM: Updated to_llm_content method

The changes to the to_llm_content method are appropriate:

1. It correctly uses the new _get_file_content method for each file in self.files.
2. The method handles the case when there are no files by returning None.
3. The implementation is concise and clear.

These changes align well with the transition to using DocumentFile and improve the overall structure of the class.

---

91-91: LGTM: Updated to_content method in Annotation class

The change to the to_content method in the Annotation class is appropriate. It now correctly calls to_llm_content() on the AnnotationFileData instance, which is consistent with the updates made to the AnnotationFileData class. This change maintains the existing behavior for other annotation types while incorporating the new file content generation logic.

---

234-238: LGTM: Updated get_chat_document_ids method

The changes to the get_chat_document_ids method are appropriate:

1. It now uses get_document_files(), which is consistent with the transition to DocumentFile.
2. The use of getattr(file, "refs", None) safely accesses the refs attribute, preventing an AttributeError if it doesn't exist in some DocumentFile instances.

These changes improve the robustness of the method while maintaining its functionality.

---

Line range hint 241-253: LGTM: Updated get_document_files method

The changes to the get_document_files method (formerly get_uploaded_files) are appropriate:

1. The method name has been updated to reflect the use of DocumentFile objects.
2. It correctly iterates through annotations to collect DocumentFile instances.
3. The method maintains its functionality while adapting to the new DocumentFile structure.

These changes are consistent with the overall transition to using DocumentFile and improve the clarity of the code.

⚠️ Potential issue

Enhance error handling and code organization in process_private_file method

The process_private_file method is comprehensive but could benefit from some improvements:

1. Consider moving the import of IndexConfig and get_index to the module level to separate concerns.

2. The error handling for the file saving operation is missing. Wrap the cls.save_file call in a try-except block to handle potential errors.

3. The conditional logic for CSV files and code executor tools could be extracted into a separate method for better readability.

Here's a suggested structure for the method:

@classmethod
def process_private_file(cls, file_name: str, base64_content: str, params: Optional[dict] = None) -> DocumentFile:
    if params is None:
        params = {}

    index_config = IndexConfig(**params)
    index = get_index(index_config)

    file_data, extension = cls._preprocess_base64_file(base64_content)

    try:
        document_file = cls.save_file(
            file_data,
            file_name=file_name,
            save_dir=PRIVATE_STORE_PATH,
        )
    except Exception as e:
        logger.error(f"Failed to save file {file_name}: {e}")
        raise ValueError(f"Could not save the file: {file_name}") from e

    if cls._should_skip_indexing(extension):
        return document_file

    document_file.refs = cls._index_file(index, document_file, file_data)
    return document_file

@classmethod
def _should_skip_indexing(cls, extension: str) -> bool:
    tools = _get_available_tools()
    code_executor_tools = ["interpreter", "artifact"]
    return extension == "csv" and any(tool in tools for tool in code_executor_tools)

@classmethod
def _index_file(cls, index, document_file: DocumentFile, file_data: bytes) -> List[str]:
    if isinstance(index, LlamaCloudIndex):
        doc_id = cls._add_file_to_llama_cloud_index(index, document_file.name, file_data)
        return [doc_id]
    else:
        documents = cls._load_file_to_documents(document_file)
        cls._add_documents_to_vector_store_index(documents, index)
        return [doc.doc_id for doc in documents]

These changes improve error handling, readability, and maintainability of the code.

⚠️ Potential issue

Enhance error handling in _preprocess_base64_file method

The _preprocess_base64_file method is concise but lacks error handling. Consider the following improvements:

Add error handling for potential ValueError when splitting the header and for binascii.Error when decoding the base64 data:

import binascii

@staticmethod
def _preprocess_base64_file(base64_content: str) -> Tuple[bytes, Optional[str]]:
    try:
        header, data = base64_content.split(",", 1)
        mime_type = header.split(";")[0].split(":", 1)[1]
        extension = mimetypes.guess_extension(mime_type)
        if extension:
            extension = extension.lstrip(".")
        return base64.b64decode(data), extension
    except (ValueError, binascii.Error) as e:
        logger.error(f"Error preprocessing base64 file: {str(e)}")
        raise ValueError("Invalid base64 content") from e

This change adds error handling and ensures that the extension is properly processed even if guess_extension returns None.

⚠️ Potential issue

Improve error handling and code organization in _load_file_to_documents method

The _load_file_to_documents method is well-structured, but there are a few areas for improvement:

1. Consider moving the logic for choosing the reader into a separate method for better readability:

@staticmethod
def _get_reader(extension: str):
    reader = _get_llamaparse_parser()
    if reader is None:
        reader_cls = _default_file_loaders_map().get(f".{extension}")
        if reader_cls is None:
            raise ValueError(f"File extension {extension} is not supported")
        reader = reader_cls()
    return reader

2. Add error handling for the reader.load_data call:

try:
    documents = reader.load_data(Path(file.path))
except Exception as e:
    logger.error(f"Error loading file {file.path}: {str(e)}")
    raise ValueError(f"Failed to load file: {file.name}") from e

3. Consider using a dictionary for the custom metadata:

custom_metadata = {
    "file_name": file.name,
    "private": "true"
}
for doc in documents:
    doc.metadata.update(custom_metadata)

These changes will improve the robustness and readability of the _load_file_to_documents method.

🛠️ Refactor suggestion

Improve file name sanitization for edge cases

The _sanitize_file_name function is simple and effective, but could be improved to handle edge cases:

Consider the following improvements:

1. Preserve the file extension.
2. Handle leading/trailing spaces and dots.
3. Ensure the sanitized name is not empty.

Here's an improved version:

def _sanitize_file_name(file_name: str) -> str:
    """
    Sanitize the file name by replacing all non-alphanumeric characters with underscores,
    preserving the extension, and handling edge cases.
    """
    name, ext = os.path.splitext(file_name)
    sanitized_name = re.sub(r'[^a-zA-Z0-9]', '_', name.strip())
    sanitized_name = sanitized_name.strip('._')
    if not sanitized_name:
        sanitized_name = 'unnamed_file'
    return f"{sanitized_name}{ext}"

This version ensures that the file extension is preserved, leading/trailing spaces and dots are removed, and an empty file name is replaced with a default value.

⚠️ Potential issue

Add error handling to _get_llamaparse_parser function

The _get_llamaparse_parser function is well-structured, but lacks error handling. Consider the following improvements:

Add error handling for potential exceptions:

def _get_llamaparse_parser():
    try:
        from app.engine.loaders import load_configs
        from app.engine.loaders.file import FileLoaderConfig, llama_parse_parser

        config = load_configs()
        file_loader_config = FileLoaderConfig(**config["file"])
        if file_loader_config.use_llama_parse:
            return llama_parse_parser()
        else:
            return None
    except ImportError as e:
        logger.error(f"Failed to import required modules: {str(e)}")
        return None
    except KeyError as e:
        logger.error(f"Missing key in configuration: {str(e)}")
        return None
    except Exception as e:
        logger.error(f"Unexpected error in _get_llamaparse_parser: {str(e)}")
        return None

This change adds error handling for potential import issues, missing configuration keys, and other unexpected errors. It also logs the errors for better debugging.

⚠️ Potential issue

Address security concern and enhance metadata inclusion

The new _get_file_content method effectively encapsulates the logic for constructing file content for LLM. However, there are two points to consider:

1. Security concern: The sandbox file path construction on line 64 could be vulnerable to path traversal attacks.
2. Additional metadata: Consider including more metadata from DocumentFile in the content.

To address the security concern, sanitize the file name:

+ from pathlib import PurePath

- sandbox_file_path = f"/tmp/{file.name}"
+ safe_file_name = PurePath(file.name).name
+ sandbox_file_path = f"/tmp/{safe_file_name}"

To include additional metadata:

 if file.refs is not None:
     default_content += f"Document IDs: {file.refs}\n"
+ if file.size is not None:
+     default_content += f"File Size: {file.size}\n"
+ if file.type is not None:
+     default_content += f"File Type: {file.type}\n"
 # Include sandbox file path

These changes will enhance security and provide more comprehensive file information to the LLM.

Committable suggestion was skipped due to low confidence.
