[bitbake-devel] [PATCH] toasterui: Create per-build logs
Michael Wood

Tue Oct 27 16:25:56 UTC 2015
From: Elliot Smith <elliot.smith at intel.com>
Rather than relying on bug 8411, which is conveniently creating
separate log files for each of our builds, create our own
log file for each build.
The log files are created in the same tmp directories that
bitbake users, but are timestamped to the millisecond to avoid
name collisions.
Each log file is opened on the ParseStarted event and closed
on the BuildCompleted event (or if when the build fails).
Because we start logging on ParseStarted, we're able to capture
the "Build Configuration" section output by bitbake.
