Beta of Version 4 is available

[Thomas Keffer]

Version 4 is now feature complete. There is lots of exciting new stuff, including:

• Support for Python 3
• User-defined derived types.
• More customizable logging.
• Support for Vantage LOOP2 packets.

and lots of other, little things.

The WeeWX test suites have never been better, but the one thing they can't test is hardware! We need you for that!

For the moment, V4 is available only for setup.py installs. Download it from the usual place, install, then run it on your local hardware. If you can, run it under Python 2.7, and Python 3. Report back.

Thanks in advance!!

Upgraded from the previous alpha version.  Its been running well for me and the upgrade went smoothly.  Thanks.

Installed b1 on a pi4 using my patched weatherflow-UDP driver using python3.  Looks ok.

One thing folks should remember is to be careful they pick the python of their choice (python, python2, python3, whatever your os calls it) so that all your prerequisites are present.  I keep forgetting to specify python3 in my setup.py commands :-)

[Thomas Keffer]

Thanks, Joe. Which version of Python did you use?

You should be able to install WeeWX under Python 2.7, then run under Python 3. Did you have a different experience?

How would you install under one python and tell it to run under another (short of manually running it in the foreground) ?

Wouldn't you also need all the corequisites for both versions as well ?

--

-----  vince...@gmail.com ----

[Thomas Keffer]

Install under any version you like. The only thing setup.py needs is configobj.

Then run under any version, After, of course, installing the necessary prerequisites for that version.

Personally, I've almost entirely switched to Python 3. These days, the only thing I'm using Python 2 for is to check compatibility. So, I've installed the prereqs for both versions.

[Vince Skahan]

Yup, works fine under either one here for my slightly patched WF UDP driver.

Anybody running a WF station who wants to use python3 should use the forked driver in my PR at the author's site.   I made a slight update today after some more python2 testing.  Works fine (as does weewx) under either python2 or python3.

[gjr80]

Just a note for anyone who may be toying with the new --calc-missing functionality in wee_database; it is broken in the current beta (b1). I should have a commit that fixes it this afternoon and I guess that will appear in the next beta.

Thanks, Hartmut! That's exactly the kind of testing we're looking for!

Fixed in commit f1c50ae. If you want to fix your version, replace the file /home/weewx/bin/weewx/xtypes.py with this.

Is there a problem with secondary db ?

I'm trying to update my odds+ends skins/extensions to v4 and every one that creates/uses an alternate db fails to initialize similarly. Figuring Matthew's code would be a better test case than mine, I grabbed pmon.py as a reference implementation and that fails exactly the same way:

Using Version 4 Beta, Raspberry Pi, and Python3.  The Meteotemplate is giving these errors.  I was able to correct the second one by changing the

 

 

except KeyError, e: to except KeyError as e: on line 106 and

 except weewx.ViolatedPrecondition, e: to  except weewx.ViolatedPrecondition as e: on line 123

 

I have no idea about the Queue error.

The problem was with old-style schemas (see the upgrading guide if you're interested). Fixed in commit c99c25e.

That fixed that problem, but pmon still doesn't seem to be working, at least for me. Perhaps you can investigate further?

Tom,

These are problems in meteotemplate, which does not seem to have been ported to Python 3. You'll have to ask the author for fixes (it is not part of WeeWX).

Yup - works for me.  Thanks.

 

That fixed that problem, but pmon still doesn't seem to be working, at least for me. Perhaps you can investigate further?

After applying that commit, it's very close.

Looks like the utf-8 thing that I ran into on the WF UDP driver.

Run through "2to3 -w" to fix up the print statements, then insert one line ala:

              cmd = 'ps aux'

              p = Popen(cmd, shell=True, stdout=PIPE)

              o = p.communicate()[0]

              o = str(o,'utf-8')                     # <== needed for python3

              for line in o.split('\n'):

                  if line.find(self.process) >= 0:

                      m = self.COLUMNS.search(line)

At that point for me, after the manager.py edits, pmon seems to work ok in at least its standalone test mode.

[Thomas Keffer]

Gary, did you get this under the commit I just did an hour ago? If so, try the development branch now. I reverted that commit.

Hartmut, another question: are you sure the problem is in the following plot?

        [[[weekrain]]]
            yscale = None, None, 0.02
            plot_type = bar
            [[[[rain]]]]

                aggregate_interval = 86400
                label = Rain (mm/Day)

How did you determine this was the problem?

Good morning from Germany

Hallo Tom

the problem is not in the skin.conf because in all other works xtypes.py correctly.

Ich suche noch die Ursache für diese konkrete Fehlermeldung aber an der skin.conf liegt es nicht.
I'm still looking for the cause of this specific error message but the skin.conf is not.

Probable nit, but I see a bare comma in the value on the data_services line in the b1 weewx.conf file.  Is that meaningful or just something extraneous ?

[Thomas Keffer]

Meaningful. That’s how configObj knows it’s a list, and not a single value.

Hallo Tom,

wie wird den einzelnen Werten aus der Datenbank die Funktion "sum" wie zum Beispiel bei ($day($data_binding='wd_binding').cooldeg.sum) zugewiesen, denn hier vermute ich den 

raise weewx.UnknownAggregation(aggregate_type)
        ****  weewx.UnknownAggregation: sum

Des Weitern, gibt es eine Funktion "alltime" in der Version 4.0.0b1

-----------------------------------------------------------

how is the individual values from the database assigned the function "sum", such as ($ day ($ data_binding = 'wd_binding'). cooldeg.sum), because here I suspect the error

raise weewx.UnknownAggregation (aggregate_type)
         **** weewx.UnknownAggregation: sum

Furthermore, there is a function "alltime" in version 4.0.0b1

Gruss Hartmut

[Thomas Keffer]

I am unable to reproduce this error, nor do I understand the context in which it is happening. 

Could you please:

1. tar up your report 'CalendarReport'
2. take out any passwords in weewx.conf. You can use the utility wee_debug to do this.

Then send them both to me. tke...@gmail.com

I am sorry, Hartmut, but that skin has an extraordinary number of custom databases, bindings, templates, search list extensions, observation types, and generators that I can't possibly debug it.

You're going to have to get the problem down to something simple, using standard WeeWX facilities.

I'm throwing various extensions  that I have collected at the beta, so feel free to push back if the problem needs an update to the extension.

Under python 2 I am getting this:

I wrapped the line in a try/except to print out some variables, so it is actually line 655 in xtypes

Here are the values for select_stmt, aggregate_type, and row

SELECT windGust, windGustDir, usUnits FROM archive WHERE windGust = (SELECT MAX(windGust) FROM archive WHERE dateTime > 1574139600 AND dateTime <= 1574143200  AND windGust IS NOT NULL)

max

(0.0, None, 1)

[Thomas Keffer]

You're making it easy! 

Turns out the vector arithmetic got neglected as well. I think I got it all fixed in commit 073be00. You can just download xtypes.py if you want to patch your copy, or do a pull on the repository.

What is type 'rain-ET'? Is it defined in the schemas for bindings wx_binding and wd_binding?

If it is not defined, you will get this error. With beta 3, I've improved the error message.

this is not a datentype

it is an operation rain minus ET

At some point here was reported in the forum about it

I have graphically compared the two different calculations
rain sum minus evaporation water balance

but has no relevance anymore

Unfortunately, the ImageGenerator does not allow you to use an expression as a data type; only type that appear in the schema, or as an xtype.

Defining a new xtype is not terribly hard. It would look something like this (NOT TESTED):

File user/rainet.py:

import weewx.units
import weewx.xtypes

class RainET(weewx.xtypes.XType):

    @staticmethod
    def get_scalar(obs_type, record, db_manager=None):

        if obs_type != 'rain-ET':
            raise weewx.UnknownType

        rain = record.get('rain')
        ET = record.get('ET')

        if rain is not None and ET is not None:
            record['rain-ET'] = rain - ET

    @staticmethod
    def get_aggregate(obs_type, timespan, aggregate_type, db_manager, **option_dict):

        if obs_type != 'rain-ET':
            raise weewx.UnknownType
        if aggregate_type != 'sum':
            raise weewx.UnknownAggregation

        sql = "SELECT SUM(rain - ET) FROM %s WHERE dateTime>? AND dateTime<=?;" % db_manager.table_name

        row = db_manager.getSql(sql, timespan)

        if row is not None:
            value = row[0]
        else:
            value = None

        # There is probably a more elegant way of doing this:
        if db_manager.std_unit_system == weewx.US:
            unit = 'inch'
        elif db_manager.std_unit_system == weewx.METRIC:
            unit = 'cm'
        else:
            unit = 'mm'

        vt = weewx.units.ValueTuple(value, unit, 'group_rain')
        return vt
# Insert my new class into the xtypes system:
weewx.xtypes.xtypes.append(RainET())

The final detail is that you have to make sure this file gets run, so that the new type will get inserted into the xtypes system. The easiest is to import it from a file that you know will get executed before the reporting happens.

import user.rainet

Hartmut, on reflection, I recall the discussion in the forum about being able to use simple expressions in aggregates.

I will try to modify the xtypes facility to accommodate this.

Thanks for reminding me.
