Lino under Python 3

I found a solution for #1036. I don’t understand why, but the problem disappeared when I added universal_newlines=True to my Popen() calls.

As a result, atelier now passes again under both Python versions on Travis CI.

While I was there, I cleaned up the failures of the Lino test suite under Python 3.

I still don’t trust in the atelier.utils.dict_py2() function, I prefer to use json.dumps(). Anyway both methods failed on dicts with more than one item. I converted snippets like this:

>>> dict_py2(expr)
{'name_de': 'Hallo', 'name': 'Hello'}


>>> expr == {'name_de': 'Hallo', 'name': 'Hello'}

I also had problems with snippets like this:

>>> import json
>>> print(json.dumps(list(streets_of_eupen())[:5]))
["Aachener Stra\u00dfe", "Akazienweg", "Alter Malmedyer Weg", "Am Bahndamm", "Am Berg"]

My lesson here was that json.dumps() cannot be used when the output contains non-ASCII characters…

Next result: also the The Lino core Lino Core lino now passes again under both Python versions on Travis CI.

Protecting against spam

Andi explained me why my IP address had been regarded as a spammer. The postfix I am running there did no SPAM control at all. Mails arriving at adresses like or were happily forwarded to Now that Lino was getting more known, there is more spam arriving at these adresses. This never disturbed me because I use Thunderbird which has a good spam filter.

The problem is that Elisa started to increase their spam controls. Which actually is not a problem but a good thing. So they accused me of polluting the Internet with Spam, they didn’t know that I was polluting only my own inbox.

I now read this and other sources, and configured my Postfix to do at least the basic hygiene.
