[PATCH 7/7] api: Expose events

Wed Oct 21 09:40:47 AEDT 2015


One interesting thing to be doing is polling for new events on a
project. Right now, the only event is series-new-revision, so listening
to events is really just listening to series creation and update.

This is quite useful for testing infrastructures, knowing when a series
is ready to be tested so a bot can retrieve its patches and test them.

+At the moment, only one event is listed:

+- **series-new-revision**: This event corresponds to patchwork receiving a
+  full new revision of a series, should it be the initial submission of
+  subsequent updates. The difference can be made by looking at the version of
+  the series.
+
 API Revisions
 ~~~~~~~~~~~~~
 
+**Revision 1**
+
+- Add /projects/${linkname}/events/ entry point.
+
 **Revision 0**
 
 - Initial revision. Basic objects exposed: api root, projects, series,
