This handler combines: RequestLogger: Beautiful, minimal HTTP request logging LiveReloadMixin: Server-Sent Events for hot reload SimpleHTTPRequestHandler: Standard HTTP file serving Inherits from RequestLogger, LiveReloadMixin, http.server.SimpleHTTPRequestHandler Attributes Name Type Description _html_cache dict[tuple[str, float], bytes] Methods 5 end_headers 0 None Caret Right def end_headers(self) -> None handle Override handle to suppress BrokenPipeError tracebacks. 0 None Caret Right def handle(self) -> None Override handle to suppress BrokenPipeError tracebacks. translate_path Override translate_path to ensure it never returns None. In Python 3.14, when … 1 str Caret Right def translate_path(self, path: str) -> str Override translate_path to ensure it never returns None. In Python 3.14, when self.directory is None and os.getcwd() fails, translate_path returns None. This causes crashes in the parent class's do_GET() -> send_head() -> os.path.isdir(path). We guard against this by falling back to the configured directory. Parameters 1 path str Returns str do_GET Override GET to support SSE and safe HTML injection via mixin. Request flow: -… 0 None Caret Right def do_GET(self) -> None Override GET to support SSE and safe HTML injection via mixin. Request flow: Serve SSE endpoint at /bengal_reload (long-lived connection) Try to serve HTML with injected live-reload script Fallback to default file serving for non-HTML send_error Override send_error to serve custom 404 page. 3 None Caret Right def send_error(self, code: int, message: str | None = None, explain: str | None = None) -> None Override send_error to serve custom 404 page.

Pre-initializes headers and request_version to avoid AttributeError when tests bypass normal request parsing flow. The parent class will properly set these during normal HTTP request handling. _might_be_html Quick check if request might return HTML.

This is a fast pre-filter to avoid buffering responses that are definitely not HTML (like CSS, JS, images). Parameters 1 path str Request path Returns bool — True if request might return HTML, False if definitely not HTML _is_html_response Check if response is HTML by inspecting headers and content. 1 bool Caret Right def _is_html_response(self, response_data: bytes) -> bool Check if response is HTML by inspecting headers and content. Parameters 1 response_data bytes Complete HTTP response (headers + body) Returns bool — True if response is HTML, False otherwise ← Previous reload_controller Next → request_logger List © 2025 Bengal ᓚᘏᗢ window.BENGAL_LAZY_ASSETS = { tabulator: '/bengal/assets/js/tabulator.min.js', dataTable: '/bengal/assets/js/data-table.js', mermaidToolbar: '/bengal/assets/js/mermaid-toolbar.9de5abba.js', mermaidTheme: '/bengal/assets/js/mermaid-theme.344822c5.js', graphMinimap: '/bengal/assets/js/graph-minimap.cc7e42e3.js', graphContextual: '/bengal/assets/js/graph-contextual.440e59c6.js' }; window.BENGAL_ICONS = { close: '/bengal/assets/icons/close.911d4fe1.svg', enlarge: '/bengal/assets/icons/enlarge.652035e5.svg', copy: '/bengal/assets/icons/copy.3d56e945.svg', 'download-svg': '/bengal/assets/icons/download.04f07e1b.svg', 'download-png': '/bengal/assets/icons/image.c34dfd40.svg', 'zoom-in': '/bengal/assets/icons/zoom-in.237b4a83.svg', 'zoom-out': '/bengal/assets/icons/zoom-out.38857c77.svg', reset: '/bengal/assets/icons/reset.d26dba29.svg' }; Arrow Up X -------------------------------------------------------------------------------- Metadata: - Author: lbliii - Word Count: 1408 - Reading Time: 7 minutes
