## Repairing failures on Travis¶

Tonis and I released Atelier 1.0.5. Mainly for some subtle issues with Python 3 which caused failures on Travis.

Tonis asked me whether I can see an explanation for the failing voga build 78. Indeed a surprising effect. It looks as if the numbering of some invoices were different on Travis than on my machine.

We added a list of all invoices to the Sales management in Lino Voga document which lead to build 79 on travis This is where Tonis had to leave.

Looking at this failure made me guess a probable reason for this failure: lino_voga.lib.courses.models.Enrolment.get_invoiceables_for_plan() (i.e. the get_invoiceables_for_plan implementation of an Enrolment) sorted the suggestions only by date. And the demo data has cases with more than one suggestion on a same day, so the ordering was unpredictable in these cases. So I was exited after the commit (that’s one of the psychological challenges when fixing a failing travis build: you need to wait more than a minute before seeing the result. But after 5 min 17 sec: yes!

I can imagine that Tonis had no chance of finding this because he knows not enough about what Voga does.

Maybe we should organize a Vigala Code Camp : a whole day just for an in-depth Lino Voga end-user training. I would also invite Jüri and maybe some non-programmers who might be interested in Voga.

## Some subtle documentation issues¶

There was at least one circular references in our doctrees: book referred to some project doctrees (presto, extjs), but cosi referred to book. Should The Lino Book be able to refer to Lino Così? Or rather the other way round? I think the latter.

Note that this blog “knows” all projects, can refer to them. That’s why it must build last.

Code change: atelier.sphinxconf.interproject.configure() now has a new optional parameter prjspec. This is used by book because we want it to intersphinx only to atelier.
