We don't break builds (no!)

But we suffer the build breaks of others

Build breaks aren't related to frequency of builds
The majority of build errors are dependency-related
C++ - more errors to fix than Java, but easier

Project Vision

  • Build break wakes up Furby - 10 second nudge
  • Breaks on top - n * 10 seconds
  • Wake up every 20 minutes to nudge if it's still broken
  • Build fixed - hoorah message!

ARDUINO NICETIES

  • Timers via milli() checks
  • Downsizing a library to fit
  • DHCP tradeoffs
  • #define DEBUG

Timers
.. in runFurby
retryVal = millis() + (1000 * 60 *20)

.. in checkFurbyState
if (millis() > retryVal) {
runFurby(badResultCount, false);
}

Improvements

  • Jenkins notifications - stubbed, needs testing
  • Arduino with more flash memory - support DHCP
  • Run webserver from Arduino to set job information

'SHARE THE FURBY PAIN' models

  • Rotate per sprint
  • 'Trophy' for builds broken
  • Grumpy buildmaster approach
