Subject: bitbake: event: Don't write duplicate logs to stdout and stderr in no UI case
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=25e52d34d06f800b38824fc21799dc43b31093f2;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git

bitbake: event: Don't write duplicate logs to stdout and stderr in no UI case

This code would duplicate messages to stdout and stderr when no UI connected
and there were error level messages.

Rework the code so it either uses stderr (for errors and above) or
stdout for warnings/debug but not both for the same messages.

(Bitbake rev: 45cff5734ba2ba8c8d36d17d722a5804d39b258b)
