commit 678e8dfdc377e304bbe8e0617de1442a04a8c873
Author: Gustavo Sverzut Barbieri <barbi...@profusion.mobi>
Date: Tue Dec 6 14:06:54 2016 -0200
eo_debug: add lifecycle debug options, allow run-in-tree and use eina_btlog.
As usual with our code, EFL_RUN_IN_TREE=1 will lead to usage of
binaries from the current build dir instead of system.
To make user life easier, add -l/--lifecycle-debug and
-L/--lifecycle-no-debug options, as well as -h/--help. The
lifecycle-debug option will export the correct environment variables,
such as EO_LIFECYCLE_DEBUG, EO_LIFECYCLE_NO_DEBUG and
EINA_LOG_LEVELS=eo_lifecycle:4 if no such level was set for that
domain.
Last but not least, pass all command's stderr thru eina_btlog so
backtraces are automatically translated to function names, files and
lines. This one was a bit trickier to respect colors and stdout/stderr
contents, see comments in the script.
