has_fix() only checks that fix-mode is set (2d/3d), but altitude and
other fields may not yet be populated in the operational datastore when
gpsd is still processing its first NMEA cycles after boot. Calling
verify_position() immediately after has_fix() passes can therefore race
and fail with:
KeyError: 'altitude'
This manifests reliably on the second GPS receiver (gps1) after reboot,
because it is initialized slightly later than gps0 and hits the window
where fix-mode is set but altitude has not yet appeared.
not ok 11 - Verify gps1 position is near the coordinates
# Traceback (most recent call last):
# File "test/case/hardware/gps_simple/test.py", line 29, in verify_position
# alt = float(state["altitude"])
# ~~~~~^^^^^^^^^^^^
# KeyError: 'altitude'
Add has_position() to infamy/gps.py, which gates on fix-mode AND all
position fields (latitude, longitude, altitude, satellites-used) being
present. Replace the has_fix() polls in both the pre- and post-reboot
verify steps with has_position().
