having moved to 4.0.0/python3.7 last night i see a couple of anomalies i did
not notice in testing.
the following one is mainly cosmetic but i think i have a fix for it
uptime_os (in the “About Station” part of Season skin) presently reports
obviously incorrect value:
Server uptime
18393 days, 0 hours, 10 minutes
WeeWX uptime
0 days, 8 hours, 35 minutes
WeeWX version
4.0.0
looking in weewx/station.py:
try:
# For MacOs:
from Quartz.QuartzCore import CACurrentMediaTime
os_uptime_secs = CACurrentMediaTime()
except ImportError:
a simple test shows the ImportError option is being exercised:
from Quartz.QuartzCore import CACurrentMediaTime
os_uptime_secs = CACurrentMediaTime()
print(os_uptime_secs)
print(os_uptime_secs/float(3600))
and python3.7 (from macports) gives
Traceback (most recent call last):
File "/Users/graham/a.py", line 1, in <module>
from Quartz.QuartzCore import CACurrentMediaTime
ModuleNotFoundError: No module named 'Quartz'
but python2.7 (from macos platform), where 3.9.1 worked fine, gives
815589.697895
226.55269386
reading weewx/station.py, the consequence of following the Import exception is
that os_uptime_secs remains unset i.e. a garbage value
unfortunately i can’t install the missing module Quartz under python3.7:
sudo python3.7 -m pip install Quartz

Collecting Quartz

FileNotFoundError: [Errno 2] No such file or directory: 'requirements.txt'
consulting doctor google, i came across module uptime, which i installed using
python3.7 -m pip.
purportedly it is cross-platform including linux and linux-like. it seems to
give the correct result for macos and, if it really is cross-platform, could
simplify weewx/station.py by avoiding testing for each platform itself
import uptime
secs = uptime.uptime()
print(secs)
print(secs/float(3600))
gives good values on my mac server:
817999.84659
227.22217960833333
but it is a dependency on another external module
