Force log level at exec time
As a CEP developer
I would like to change the log level and parameters at run time
So that I don't have to re-compile my executable eveytime I need to check something or diagnose a problem
Epic/Topics Log system

Description / Overview

Choose one of (or both) solution:

  1. enable the possibility to force the log parameter using environment variable, e.g.::ab:
CAMITK_LOG_LEVEL=WARNING CAMITK_LOG_TO_STDOUT=FALSE CAMITK_LOG_TO_FILE=TRUE CAMITK_LOG_FILE_DIRECTORY=/tmp camitk-imp"

to force camitk-imp running with these log parameters instead of those defined in source or settings Caveat: you need to modify the environment variable and access to it from the code. Not really a problem, but can be tricky for people who don't understand it properly, modify their global environment (e.g. in ~/.bashrc) and then forgot they had define these things.

  1. manage a --debug=[options] argument from the command line execution for all CamiTK application with different options:
log level:
le (error)
lw (warning)
li (info)
lt (trace)

d (display debug)

s (display time stamp)

log message:
me
mw
mi
mt
p

Hints

  • Use Qt to read the environment variables and modify the application properties accordingly
  • Add a flag to camitk-imp and camitk-config arguments

Acceptance tests

  • there are more tests of the testlogger class that shows it work
  • the Log System document is updated accordingly
