Feature/pingback: change pingback to use model for storing pings. Fixes #40

[white-gecko]

This feature branch fixed issue #40 by storing the ping in a model (config option)
furthermore it fixes some issues which occurred in the pingback (separate commit)

Can I ask you to add some tests?

[white-gecko]

Yes you can, but I don't really know how to use the test environment for this. I need a store with two models, where one already contains a resource. And I need predictable output from the internet or the wrapper.

But for sure this would be helpful to have a test, because I want to add further features. Maybe we can use this as an example for a testing workshop :-)

[white-gecko]

I wrote two tests which succeed when running with phpunit Erfurt/PingTest.php inside tests/unit/ but there is a problem with Versioning if I run it with make test-unit which I don't understand.

Maybe @pfrischmuth could take a look at the tests?

[seebi]

@pfrischmuth Can we merge this?

[seebi]

can not merge since make testfailes:
...................................................PHP Fatal error: Call to a member function getUri() on a non-object in /Users/seebi/Projects/OntoWiki.git/libraries/Erfurt/library/Erfurt/Versioning.php on line 606

[white-gecko]

That is the problem, which I have to discuss and examine with @pfrischmuth
