With the release of orekit 12.2, the python-wrapper based on JCC (“Classic”) is now also released. This includes the updates of the main orekit projects as well as some minor fixes.
One important breaking change is that in 12.2, a new default method “finish(…)” is introduced in EventHandler and EventDetector. This is exposed in the PythonEventHandler and PythonEventDetector and needs to be included in that class in order to see these classes complete. This is a minor update to the code, but a breaking change.
For PythonEventDetector, add:
def finish(self, state):
pass
For PythonEventHandler, add:
def finish(self, finalState, detector):
pass
In java version this is not a problem as it has default methods.
The alternative wrapper, orekit_jpype will be released in short. For new projects, this jpype based version is recommended.
It could be interesting to add a set of python code to run in the CI to automatically detect braking changes in the python wrapper ? What do you think @sdinot ?
I don’t know about this. For me, the main code is Java. The wrapper is really… well, a wrapper. So it’s not guaranteed that code will run as is from one version to the other, even minor. JCC introduces overhead that I believe could dragg us down if we tried to not break anything there as well. I mean sometimes we discover that a Python class is missing altogether, so there is a discrepancy with Java anyway.
