Store the two-digit WS id (colored when stderr supports color, plain
otherwise) in the ASGI scope state so user code can include it in its
own log lines via websocket.state.logid.
Move terminal helpers (use_color, strip_ansi, display width) into a new
dependency-free fastapi_vue.tty module, absorbing termwidth.py, to keep
imports one-directional and avoid the logging/accesslog cycle.
App-supplied extra fields may carry raw ANSI color codes without a
reset, bleeding into the next line's IP column and following output.
Ensure access log lines begin and end with a reset, adding one only
where missing to avoid duplicate resets on well-formed lines.
Optionally usable early in CLI mains, devservers and scripts that log
before (or without) server.run(). Shares patch_log_config with the
server path (same log_config overrides), but installs no server-side
patches: Formatter gains an install flag gating the lifespan/error
middleware monkeypatches, and the NullHandler backdoor is skipped.
dev=None follows env.dev for the root level, True/False override it.
Pre-existing loggers survive the dictConfig (disable_existing_loggers
is set False).
A partial log_config (no "version" key) is deep-merged over uvicorn's
default config before our patching, so users pass only their
customizations, e.g. log_config={"loggers": {"myapp": {"level":
"DEBUG"}}}. Previously such dicts crashed at startup: dictConfig
requires a version, and our root entry referenced a "default" handler
that might not exist; that reference is now only added when the handler
exists. The stock default formatter is replaced only when untouched,
so an overlaid fmt survives. Dicts with version and non-dict configs
behave as before. Documented in the README logging section, with tests
under fastapi-vue/tests (each patched config validated through
dictConfig).
The root logger entry patch_log_config adds now uses INFO in dev and
WARNING in production (Python's default), so third-party library INFO
noise stays silent in production while subloggers remain free to
define their own level overrides. A user-supplied root level still
wins (setdefault).
staticfiles now logs via its own module logger instead of
uvicorn.error: the startup stats line shows in dev (root INFO) and is
hidden in production, and it no longer passes through the
uvicorn-quiet filter that silently ate it.
The kanta logger/handler/formatter block is removed: kanta configures
its own event loggers at import time as of its logging rework, and its
diagnostics follow the root logger like any other library.
run() gains access_log (default on) and log_config parameters. When
enabled, uvicorn's own access log is disabled (access_log=False) and
replaced by an ASGI middleware (adapted from the uvicorn access-log
branch) that logs colored request lines, WebSocket open/close pairs,
and pre-accept rejections in open format.
log_config dicts (uvicorn's default or user-supplied) are patched
best-effort via a registered patch pipeline in fastapi_vue.logging:
swapping in our AccessFormatter, routing our output to a private
fastapi_vue.access logger (uvicorn gates its protocol-level access
logging on uvicorn.access.hasHandlers(), so that logger must stay
handlerless), and filtering stock WebSocket handshake chatter from
uvicorn.error. Non-dict or structurally unexpected configs pass
through untouched.
The middleware is installed by patching Config.load/load_app, hooked
into AccessFormatter instantiation so reload/worker subprocesses
(which re-apply log_config without re-calling run()) are covered.
