[issue6958] Add Python command line flags to configure logging

Marc Abramowitz added the comment: I guess I should be more specific about the 12factor thing I just mentioned, because http://12factor.net/logs says: >>> A twelve-factor app never concerns itself with routing or storage of its output stream. It should not attempt to write to or manage logfile

Marc Abramowitz added the comment: I was just thinking that it would be nice if logging could be configured through environment variables. This would make it easier to have Python applications adhere to the Twelve-Factor methodology around application configuration: http://12factor.net/config

[issue6958] Add Python command line flags to configure logging

Vinay Sajip added the comment: Ok. I think it's a reasonable request, but I can see that implementing it naively without some further thought will lead to (justifiable) complaints from some users that the behaviour is contradictory or unintuitive in terms of which configuration "wins" in the eve

Thomas Heller added the comment: I retract this request. It seems the idea is not liked or a solution is not easy. (The solution I now use is to start Python from a batch file that parses some command line flags itself, sets environment variables, and my sitecustomize.py file configures loggin

Vinay Sajip added the comment: @theller: Although your use case just covers using basicConfig, I can just see users expecting the same mechanism to invoke configuration stored in a logging configuration file, which is why I suggested the config= variant. However, doughellmann raises the valid po

Doug Hellmann added the comment: @theller, I'm not sure what your point is. I'm asking what the defined behavior is if we provide some sort of global way to run a program with logging configured, and then that app turns around and tries to reconfigure it. Should the last one to call the config

R. David Murray added the comment: I don't think this is about logging in stdlib modules that are run directly. I think this is about a library that contains logging calls (eg: multiprocessing), and is used in j-random-application, and while prototyping/debugging the application you want to acce

Vinay Sajip added the comment: If we do include interpreter support, there should be an option to invoke a configuration file, too: -l config=path Mutually exclusive with all the other options. So, you can either use it to invoke basicConfig or to invoke an arbitrary configuration in a file.

New submission from Thomas Heller : I want the Python executable to have command line flags which allow simple configuration of the logging module. Use cases are to run applications/scripts (which use libraries that use logging calls) with different logging output without having to edit (ugly) l
