Deleting XML files after import

#505 : cpaseupen reports that their xml have not been deleted by the cron job. Although they should have been. I added another logger message. When trying with the new version, I got an OSError which indicated that maybe it was just a permissions problem.

Handling the overwhelming flow of tickets

Do you know that situation when there is so much to do that managing your to-do list becomes the most important and time-consuming activity? This is my main challenge for the moment. This is why my customers are perceiving slow evolution regarding to their own tickets (which they submitted).

But don’t panic. It has a good side. Lino finally started to be maintained by a team and no longer by a single person. After years of just dreaming about it.

An urgent problem is therefore to optimize Lino Noi for helping us with this task. That’s why I invested yet another day into #559.

I generalized the notification system and moved it out of lino.modlib.stars into a new plugin lino.modlib.notifier.

I worked on the email’s body template so that the content starts to be helpful. On topic was the following.

The server URL

One problem was that we need to include the address of the server in a change notification mail:

Please visit http://lino/api/stars/Notification/1234 in order to view all subsequent changes on this object.

But the server process itself does not know how it is being served to their users. We usually know it by inspecting the incoming http request. But since the send_email method is being called from a Django post_save signal, we don’t know that incoming http request.

So do we need a field server_url per User? Even this would fail if a given users happens to use Lino on different machines using different URIs.

So maybe as a first approach we could simply add a new field lino.core.site.Site.server_url with the “canonical” or “most often used” URI. And users who access Lino from a different location using an alternative URI must adapt the link themselves.

And since lino.core.site.Site somehow replaces Django’s sites framework, we might name it domain and remove the leading "http://". (No, I won’t go that far because I don’t see why it should be useful)

Rendering the notification message

I am still fiddling with how to render the notification message. Okay for the momennt it seems to work. But I had to write a new method lino.core.renderer.TextRenderer.obj2html() which indicates that the API is not yet optimal…

Documentation

I added a new section to the Developer’s Guide Install your Lino developer environment:

http://lino-framework.org/dev/install.html#updating-your-copy-of-the-lino-sources

count() takes exactly one argument (0 given)

This TypeError occurred in lino.projects.polly when displaying the detail of a Poll.

Deployed to lf.org with Hamza

Fixed ticket #38 with Hamza

Hamza and I fixed the last remaining failures for #38: the Lino test suite now passes in both Django 1.6 and 1.8.
