V4.0.0b4 is up

[Thomas Keffer]

In the usual place. 

What we really need is testing of the drivers, particularly under Python 3. If you have something other than a Vantage, please install and check it out!

Tests fine on a pi4 with current Raspbian using:

• WeatherFlow UDP driver 1.03 - my fork with 2to3 run vs. the reference copy (PR already in to author)
• purple air 0.1 - my fork with added AQI and 2to3 run vs. the reference copy (PR already in to author)
  
• mqtt 0.19 - my fork again with 2to3 run against it (no PR in)
• Belchertown 1.1b8 - no edits from author's copy
• several of my custom skins, again with 2to3 run to convert them as needed

[Hartmut Schweidler]

Hallo Tom

the driver fousb.py at line addr1 = (address // 256) & 0xff  not addr1 = (address / 256) & 0xff

the driver in https://github.com/hes19073/hesweewx/blob/master/bin/weewx/drivers/fousb.py

works by python 3

Gruss Hartmut

[Thomas Keffer]

Thanks, Hartmut!

Alternatively, how about

    addr1 = (address >> 8) & 0xff

which makes the bit arithmetic more explicit.

Xant here, trying to jump into the "Big Boys league" (aka, development) :P

Since jumping to next up, went to duplicate and upgrade everything:

• Rpi3 to Rpi4 - check!
  
• Bskin 1.1b7 to Bskin 1.1b8 - check!
• WeeWX 3.9.2 to WeeWX 4.0.0b4 -error (ufff...)

NOT reportingas a bug, but probably some "silly" hands-on upgrade mistake. It seems related to DB, more than other. Some errors as the following:

1) Tried service start

Best,

Xant

[Thomas Keffer]

You're doing things right! It's just that how a schema is specified has changed in V4.0. However, the intention was to make it backwards compatible, which I obviously failed at.

Let me think about this case and I'll get back to you.

Affff... thank you Thomas.

Your note is a relief, as didn't want to make a "noobie" mistake in the Dev League (debated much prior to posting).

That said, I'm your new "b-Tester" and glad to help for any. To note, now handling two SD Rpi cards:

1. Functional 3.9.2
2. "half-way" v4 (open to any mess and tries)

But now puzzled, how others moved-on when mine didn't...

Thank you always for WeeWX, your continue development and time.

"Long live WeeWX!",

[Armando Esteves]

Tom

Hold-on on this issue, as it might not be WeeWX/DB related, but Rpi version/OS conflict (https://groups.google.com/d/msg/weewx-development/ZXChMjAGUjM/RGlnAUzYBAAJ).

Will inform back upon new developments and when ready for further b-Tests.

X

[Thomas Keffer]

I don't think so. It's definitely a problem. Fixed in commit 55f9cb3.

Uploaded V4.0.0b5.

Ok.... Rpi4 now resting on side while we go "baby steps".

Downloaded V4.0.0b5 and started all over from working 3.9.2.

• No error upon rebuilding Database here (but to note that I used Rpi4 - with Rpi3 SD card - which could led to conflict)
• WeeWX started, but its not reporting; that is per following msg upon 'wee_reports':

Were you using Python 3? If so, the problem is almost surely because the Belchertown skin has not been ported yet.

fyi - the development branch for Belchertown works nicely on python3, but changing multiple things at once can sometime come with its own adventures.....

 

[Xant]

Starting from scratch (again). PWS is WeatherFlow.

1) RPi3 WeeWX release w Bskin - all is well and running

2) RPi4 WeeWX - python 2x for now; got the following error msg:

root@RPi4:/etc/weewx# service weewx start
Failed to start weewx.service: Unit weewx.service not found.

Only place I see reference for "weewx.service" is under 'vantage.rules' (I'm not using Vantage).

weewx.conf in attach.

Vince

It seems you using WFlow and running. Any to patch?

X

[Thomas Keffer]

weewx.service is the systemd configuration file. You'll find it under util/systemd. It's used when starting weewx as a daemon.

One other thing: the weewx.conf file you enclosed is a V3.9.2 file. Are you sure you're running v4.0.0?

Please, disregard previous weewx.conf (mistaken upload).

1) Starting as: "service weewx start" (RPi4, python 2x)

2) Weewx.conf re-attached.

Yes - you need to run it through 2to3 if you want to use python3.

https://github.com/captain-coredump/weatherflow-udp/pull/9

Diffs are at https://github.com/captain-coredump/weatherflow-udp/pull/9/files if you want to take a look.  Very trivial differences due to python3.

I'd try "systemctl start weewx" and use full systemd syntax, just in case. 

[Xant]

It seems a simple path setup, but it beats me...

root@RPi4:/etc/systemd# systemctl start weewx

Failed to start weewx.service: Unit weewx.service not found.

Must declare path somewhere? Shouldn't install take care of that?

[gjr80]

As far as I am aware development versions are generally distributed as setup.py installs only and not as a (deb or rpm) package. For setup.py installs you need to manually install the service files. Refer to the Run section of the setup.py install instructions http://weewx.com/docs/setup.htm

Agree.   For a later Debian system that uses systemd, you probably want to install weewx.service into /etc/systemd/system and then run 'systemctl enable weewx' so it starts on boot.

All as root or via sudo, of course.

The Debian instructions in the setup.htm file are for systems that do 'not' have systemd, although they work on those systems too if you install the init.d file in the old locations.

Both ways work fine.

[Ralph Underwood]

Hi,

I used Vince's script to install ( that was easy).  After all worked with Simulator, I changed the driver to the Ultimeter, shut down the Rpi4 and connected the hardware and restarted.

This is my log output. I'm thinking I may need to look into USB rules or the serialutl.py python3 issue??

[Thomas Keffer]

Thank you, Ralph, for giving the Ultimeter driver a try!

Looking through the code, it appears that, under Python 3, the driver is attempting to use unicode strings, when bytes are called for. In the attached version, I've fixed the most obvious cases where this is happening, but I've probably missed a few.

Can you give it a try?

Thanks

This is the result with the new driver. I let it go several times with same result.

I think this problem may be related to this thread, which was never resolved. Hopefully, we'll get it this time.

Try this version, but before you do, not only set debug=1 at the top of weewx.conf, but also set debug_serial in the [Ultimeter] section:

debug = 1

...

[Ultimeter]

  port = XXX

  debug_serial = 1

PS:

On the site that I am replacing with the new WeeWx version, I use a MQTT based sensor and in attempting to get it working on Python 3, I get results like this:

weather b'TIME:0,INTE:75.83,INHU:33.06'

b'TIME:0,INTE:75.83,INHU:33.06'

from my Python program that writes a filepile.txt from the MQTT.

I have been struggling with those darn "b" for a couple  of hours.

Thanks for all the help!

Ralph

 

[Thomas Keffer]

Silly me. I forgot to save the characters to the buffer! Try the attached.

Those damn 'b's are because you are printing bytes or bytearrays, not strings. If you want to get rid of them, you need to convert to a string (which is unicode under Python3). This illustrates:

>>> print(b'abc)

b'abc'

>>> # This fails, because str(b'abc') returns the "informal" representation, which includes the b's:

>>> print(str(b'abc'))

b'abc

>>> print(b'abc'.decode())

abc

Thanks Tom.  WeeWx appears to be running - I'm getting output  to home/weewx/public_html/index.html.

Now to tackle the damn 'b's, should keep me busy for a few hours.

I plan on waiting a bit before adding cmom, I have been having trouble with the old system stopping, I suspect because of  a memory leak with either cmom or the Ultimeter driver. Never got a good log to determine what was happening before the crash so I am speculating. 

New system is a RPi4 with a new memory card and a RTC.  Going Python3 all the way with this station.

OK. I tried doing a wee-extension uninstall with no success.  Any hints on how/where  to remove it?  May be simpler to just start with another install of WeeWx. 

I did manage to update my program that reads the mqtt data and write to file pile.txt without those 'b's.

HA - I'm not the only person that Google is auto-correcting 'weewx' to be 'whew' on !

You could 'try' to edit cmon to make it python3 compliant by running "2to3 filename.py" and see how far you get.  The snippet you posted is definitely something 2to3 fixes.   Add the -w switch to have it write out a modified file.

[gjr80]

Appreciate you have managed to disable cmon but for future reference manual uninstallation of an extension is fairly easy once you know what to look for. There is no simple 'find this and do this', the amount of work involved and where to work depends on the extension. A skin/report based extension will likely require work on the [StdReport] stanza of weewx.conf  to disable and the skins directory to remove. A WeeWX service based extension will likely require work on the [Engine] [[Services]] stanza in weewx.conf to disable and the bin/user directory and likely other stanzas in weewx.conf to remove. More complex extension will require all of the above and possibly more.

The key is to look in the extension installer file install.py which shows the changes the extension installer made to the WeeWX setup. The key areas of the installer are the process_services, config and files settings. These settings show what will be added/changed, you essentially need to reverse these.

For the cmon service:

to disable:

1. in weewx.conf under [Engine] [Services]] comment out/remove the user.cmon.ComputerMonitor entry in the process_services setting

2. restart WeeWX

to remove:

1. in weewx.conf under [Engine] [Services]] remove the user.cmon.ComputerMonitor entry in the process_services setting

2. in weewx.conf delete the [ComputerMonitor] stanza in its entirety

3. in weewx.conf under [DataBindings] delete the [[cmon_binding]] stanza in its entirety

4. in weewx.conf under [Databases] delete the [[cmon_sqlite]] stanza in its entirety

5. in weewx.conf under [StdReport] delete the [[cmon]] stanza in its entirety

6. delete the skins/cmon directory

7. delete the file bin/user/cmon.py

8. if it exists, delete the directory bin/user/installer/cmon

9. restart WeeWX

Certainly make a backup of your install (especially weewx.conf) before removing, in fact commenting out first then deleting once you have the expected result is probably a good approach.

Gary

[Ralph Underwood]

I found most of those items, but I was still getting a bunch of errors. My system running 3.?? died a few days ago and my backups were not good so I was installing the version 4 as a replacement - consequently I had less that 24 hours data on the system I mistakenly installed cmon on.

I am interested in cmon because I want to track down why my "old" system was periodically crashing - I was suspecting a memory leak. The memory in use would just creep up, seemed to crash 

I just made a clean installation using a newly imaged card and Vince's script. Copied over the latest ultimeter driver and I am up and running.

I still have to get my MQTT stuff working again - I stumbled upon how to get the python 3 version of paho.mqtt installed yesterday, but didn't make good notes.

Thanks again to Tom, Vince and Gary!

[Thomas Keffer]

Ralph,

Try this version of cmon.py. I did a quick port to Python 3. It should work with Python 2 or 3, and under either WeeWX V3.9, or 4.0.

"Baby steps" here.... and started from scratch all over again for RPi4...

1) RPi 3b+ / stable

On the side, in parallel, and working fine with WeeWX 3.9.2 & Bskin 1.1b7

2) RPi 4 / bench test

Transposed the above to RPi4 (ie, adjust previous 3.9.2 with Seasons skin to RPi 4, rebuild db, etc).

After usual adjustments, all seems fine (prior to update to WeeWX vs4b): Day, Week, Month, but not Year... which is mostly empty.

Sure, it can be a "transfusion" issue, but urge you to click in "Year" at your side, and verify that all is Ok (sometimes, we all forget about this last click and timeframe).

If no other reports, will soon continue beta upgrade and report.

Best, X

[Rich Bell]

Just FYI, the cmon skin is one of the skins that uses the imaging library's default font. On my Pi 3, this causes a slow increase in memory usage. See, https://groups.google.com/forum/#!topic/weewx-user/qeVSNzy7Zck for any additional information I might discover.

- Rich

[Xant]

(update)

Please, disregard my previous posting as Year now showing.

After much do and starting over, WeeWX 4.0.0b5 now working with no issues on RPi4 2.7 python. Will leave for a while, and later try python 3.

[Chris Alemany]

Has anyone tried V4 on macOS yet? I am running weewx on Catalina (macOS 10.15) now so was thinking of trying to work on a procedure for installing python 3 and weewx4 over the next couple weeks.

I got the CC3000 driver running on Debian Buster in Python 2.7.16 and Python 3.7.3.

It did require changes to run on Python 3.  I’ve sent a pull request that also includes a great deal of robustness enhancements to the CC3000 driver that I have been running (on two CC3000s) for many months.  I’m hoping you can take all of this.
