logging.basicConfig(force=False) on empty handler list never initializes Formatter and Handler

Aiming to add minimalistic logging capabilities soon within starting phase of a micropythion program, one would call:

#minimalistic
logging.basicConfig(stream=stream.sys level=logging.DEBUG)
logger = logging.getLogger('thelog')

Aiming to get a fancy timestamp and information ordering, the call could look like:

# explicit formatting
log_fmt_mipy = "%(name)s - %(levelname)s - %(message)s"
log_fmt_dat_mipy = "%(asctime)s.%(msecs)03d"
logging.basicConfig(stream=stream.sys level=logging.DEBUG)
logger = logging.getLogger('thelog')

The Object "logger" as Logger instance on either case will NEVER get a working Handler and Formatter upon initialization. This is because logging.basicConfig() in (current) line 235 evaluates the list object Logger.handlers instead of the integer number Logger.hasHandlers().

NOTE: Initialization of a date format of type "asctime" within micropython, as shown in the code above, is not (yet) supported (by design) and thus requires explicit implementation efforts.

Inizia in python-stdlib/logging/logging.py intorno alla riga 235, dove basicConfig(force=False) valuta Logger.handlers. Confronta questa logica con Logger.hasHandlers() e traccia l’inizializzazione per il caso senza Handler. Il lavoro è completato quando un logger creato dopo basicConfig riceve un Handler e un Formatter funzionanti senza modificare la limitazione documentata di asctime in MicroPython.
