packages/jumpstarter-driver-opendal/jumpstarter_driver_opendal/adapter.py (4)
16-18: Enhance the docstring with more details.While the docstring explains the basic purpose, it could be more informative by:
- Explaining what anyio streams are
- Clarifying why this wrapper is needed
- Describing the functionality it provides (send/receive methods)
- """ - wrapper type for opendal.AsyncFile to make it compatible with anyio streams - """ + """ + A wrapper type for opendal.AsyncFile that implements the anyio ObjectStream interface. + + This wrapper enables opendal.AsyncFile to work with anyio's asynchronous I/O + primitives by providing compatible send/receive methods for streaming bytes. + The wrapper handles error translation between opendal.Error and anyio's + stream-specific exceptions. + """
49-51: Convert inline comments to attribute docstrings for better IDE integration.While the comments are clear, converting them to docstrings would provide better IDE support and follow Python's documentation conventions.
@dataclass(kw_only=True) class OpendalAdapter(ClientAdapter): - operator: Operator # opendal.Operator for the storage backend - path: str # file path in storage backend relative to the storage root - mode: Literal["rb", "wb"] = "rb" # binary read or binary write mode + operator: Operator + """opendal.Operator for the storage backend""" + + path: str + """file path in storage backend relative to the storage root""" + + mode: Literal["rb", "wb"] = "rb" + """binary read or binary write mode"""
54-60: Document error handling and consider making the expiration time configurable.The comments explain the logic well, but consider:
- Documenting potential error scenarios and their handling
- Making the 60-second expiration configurable
- # if the access mode is binary read, and the storage backend supports presigned read requests + # Generate a presigned URL if: + # 1. The access mode is binary read + # 2. The storage backend supports presigned read requests + # Raises opendal.Error if presigning fails if self.mode == "rb" and self.operator.capability().presign_read: - # create presigned url for the specified file with a 60 second expiration - presigned = await self.operator.to_async_operator().presign_read(self.path, expire_second=60) + # Create a presigned URL with a configurable expiration (default: 60 seconds) + expire_seconds = getattr(self, 'presign_expire_seconds', 60) + presigned = await self.operator.to_async_operator().presign_read( + self.path, expire_second=expire_seconds)
61-64: Enhance the fallback case documentation.The comment could be more specific about when streaming fallback occurs.
- # otherwise stream the file content from the client to the exporter + # Fall back to streaming if: + # 1. Writing mode is requested, or + # 2. Storage backend doesn't support presigned URLs + # This ensures compatibility across all storage backends else:packages/jumpstarter-driver-opendal/jumpstarter_driver_opendal/driver_test.py (3)
17-30: Add a high-level test description.While the step-by-step comments are clear, consider adding a high-level docstring explaining the test's purpose and what it verifies.
def test_drivers_mock_storage_mux_fs(monkeypatch: pytest.MonkeyPatch): + """ + Test the MockStorageMux driver's filesystem operations. + + Verifies: + 1. File write/read operations with absolute paths + 2. Handling of large files (10MB) + 3. Data integrity through content comparison + """ with serve(MockStorageMux()) as client:
Line range hint
49-61: Improve StaticHandler documentation and extract magic numbers.The handler could benefit from better documentation and constant definitions.
+ # Size of test content in bytes (11KB) + TEST_CONTENT_SIZE = 11 * 1000 + TEST_CONTENT = b"testcontent" * 1000 + + """ + A test HTTP handler that serves static content. + + Implements: + - HEAD: Returns content length headers + - GET: Returns predefined test content + """ class StaticHandler(BaseHTTPRequestHandler): def do_HEAD(self): self.send_response(200) - self.send_header("content-length", 11 * 1000) + self.send_header("content-length", TEST_CONTENT_SIZE) self.end_headers() def do_GET(self): self.send_response(200) - self.send_header("content-length", 11 * 1000) + self.send_header("content-length", TEST_CONTENT_SIZE) self.end_headers() - self.wfile.write(b"testcontent" * 1000) + self.wfile.write(TEST_CONTENT)
63-69: Document server lifecycle and cleanup.The server setup comments could be more comprehensive about the lifecycle and cleanup process.
- # start the HTTP server + # Start HTTP server on localhost:8080 + # Note: Using a daemon thread ensures the server is terminated with the main thread server = HTTPServer(("127.0.0.1", 8080), StaticHandler) server_thread = Thread(target=server.serve_forever) server_thread.daemon = True server_thread.start() - # write a remote file from the http server to the exporter + # Test HTTP-to-storage transfer: + # 1. Configure HTTP source using opendal + # 2. Write remote file to exporter + # 3. Cleanup server after test fs = Operator("http", endpoint="http://127.0.0.1:8080") client.write_file(fs, "test")
