Proposed changed

[alex-ber]

Hi,

I will be glad to receive permission from you to redistribute my code based on your.

I have come across your repository here https://stackoverflow.com/questions/47325506/making-python-loggers-log-all-stdout-and-stderr-messages. Quote from their: " But be careful to capture stdout because it's very fragile."
I decided to focus on redirecting stderr only to the logger. If you want you can also redirect stdout, by making 2 calls to initStream() package-level method. But, because of https://unix.stackexchange.com/questions/616616/separate-stdout-and-stderr-for-docker-run it is sufficient only to do it for stderr for me (I'm running my application insider Docker container using tty).

Usage example:
logging.config.dictConfig(kwargs[conf.GENERAL_KEY][conf.LOG_KEY]) errLogger = logging.getLogger("stderr") stdlogging.initStream(errLogger)

Configuration file (simplified):

`
general:

 log:
   version: 1
   disable_existing_loggers: False
   formatters:
     brief:
       format: "%(message)s"
     detail:
       format: "%(asctime)s %(levelname)s %(threadName)s [%(name)s.%(funcName)s] %(message)s"
       datefmt: "%Y-%m-%d %H:%M:%S"


handlers:
  console:
    class: logging.StreamHandler
    level: DEBUG
    formatter: detail
    stream: ext://sys.stdout

  all_file_handler:
    class: logging.handlers.TimedRotatingFileHandler
    level: DEBUG
    formatter: detail
    filename: "logs/stream.log"
    when: midnight
    backupCount: 10
    delay: True

  stderr_handler:
    class: logging.handlers.TimedRotatingFileHandler
    level: DEBUG
    formatter: brief
    filename: "logs/stream.log"
    when: midnight
    backupCount: 10
    delay: True

  stderr_console_handler:
    class: logging.StreamHandler
    level: DEBUG
    formatter: brief
    stream: ext://sys.stdout

loggers:
  hiyapyco:
    level: WARNING
  stderr:
    handlers: [stderr_handler, stderr_console_handler]
    propagate: False



root:
  level: DEBUG
  handlers: [all_file_handler,console]

`

The essential part is

stderr: handlers: [stderr_handler, stderr_console_handler] propagate: False

Thanks! I'm okay with your proposal. I'll look into it then merge.

Thanks, for permission. I've released your module as part of my AlexBerUtils project, see https://github.com/alex-ber/AlexBerUtils/blob/master/alexber/utils/stdlogging.py
I've written description of it here https://alex-ber.medium.com/stdlogging-module-d5d69ff7103f
