Logging and debuging facility
|
|||
|
|
=============================
|
|||
|
|
|
|||
|
|
Levels:
|
|||
|
|
DEBUG Detailed information, typically of interest only when diagnosing problems.
|
|||
|
|
INFO Confirmation that things are working as expected.
|
|||
|
|
WARNING An indication that something unexpected happened, or indicative of some problem in the
|
|||
|
|
near future (e.g. ‘disk space low’). The software is still working as expected.
|
|||
|
|
ERROR Due to a more serious problem, the software has not been able to perform some function.
|
|||
|
|
CRITICAL A serious error, indicating that the program itself may be unable to continue running.
|
|||
|
|
|
|||
|
|
There are three loggers: `console_only`, `file_only` and `both`.
|
|||
|
|
|
|||
|
|
Use: `from debug import logger` to import this facility into whatever module you wish to log messages from.
|
|||
|
|
Logging is thread-safe so you don't have to worry about locks, just import and log.
