weewx stop working after upgrading from 3.6.x to 3.9.1

[St. B.]

Hi, 

I decided (because my WU forecast where not working anymore) to update weewx to 3.9.1. on my raspberry running debian stretch.

downloaded the weewx.3.9.1.all.deb installed, and kept my conf files.

Upon install completion, no restart of the service.

When starting, weewx starts the mainloop then shutsdown, wait for RTL process shutdown and dies.

rtl runs fine from the command prompt.

when running from the command prompt weewxd starts, and dies quickly with an invalid key "windSpeed" or some other key.

These keys are in my mappings, but did not change since 3.6

I ran a full update of my raspberry and am now at deb 9.9, but still no weewx.

What obvious "you must check when updating" did I miss on this one ?

Regards;

[Pat]

Nothing jumping out. Pasting some logs and debugs would be super helpful. See Help! Posting to weewx user

Ok, 

Below is the the /var/log/messages generated when running systemctl restart weewx.

Weirdly enough systemctl start weewx does not seem to run anything.

Stack trace when running from command prompt is as follows : 

root@raspberrypi:~# weewxd /etc/weewx/weewx.conf

Traceback (most recent call last):

I'm not seeing much here for me to go on, but some more questions: did you change your database? I wonder if it's locked or modified?

What happens if you run  weewxd /etc/weewx/weewx.conf

Paste the output if/when it crashes.

The problem is not with WeeWX, but with the weewxwd3 extension you installed. It does not seem to check for missing data before attempting to calculate humidity.

Agree that WeeWX-WD has struck again and caused the error that was posted. Am sure this been fixed in a later version, I will track that one down and post a link as necessary.

I also think there is another somewhat more critical issue - refer to the highlighted lines:

It would appear that the SDR driver is being used and it is dying. Consequently no data is being received and the poorly written weewxwd3.py fails.

It may help to see a wee_debug report (make sure you check the report for sensitive info/passwords etc before posting) as well as a log extract from WeeWX startup with debug = 1 in weewx.conf.

Hi,,

You guys rock. weewxwd3 was the culprit and removing it from the conf just fixed the "not starting issue". Now I will dig into figuring what it did for me :p and why I still get no WU forecast even with the latest version.

You won’t be getting any forecast from WU using the forecast extension for the time being as it has not yet been updated to work with the new WU API. I suspect your time will be better spent looking into why the SDR driver is exiting and causing the WeeWX engine to shut down.

Ok, 

Thanks for the info regarding WU. I might give a look into this, if it is not already taken care of by someone proficient on this topic.

The SDR is not failing, it was closed by Weewx, and the message order is somehow wrong. My station is back online since this morning, and did not shutdown.

[gjr80]

This issue was fixed in v1.0.4. The v1.0.4 code was not released as a package but can be installed by following the instructions in this post.

Gary

[St. B.]

Great, I will look into this thank you.
