Maintenance release #189

Closed afedynitch closed 9 months ago

The PR is a maintenance release with the following changes:

  1. From version 1.26.2 we can build the f2py interface files natively with the public numpy release with no hacking. This has been reflected in the build chain.
  2. A quantity "called fw that was need for producing histograms of the invariant cross section E*dsigma/dp3 has been brought back to the event data. It requires the center of mass momentum pcm to be accessible from the EventKinmatics class (same as for ecm).
  3. Repair event history and pre-/appending beam particle info can now be optionally disabled by setting generator._restore_beam_and_history = False to save some CPU time when it is not needed. By default it remains on.
  4. When subclassing MCRun, for example when developing custom interaction models, the model library may not be called chromo.models.library_name. To get this flexibility, the MCRun base class is searching under the previous path chromo.models for library name and if it fails tries just library_name.
  5. __hash__ for EventKinematics such that instances can be dictionary keys.
  6. Fixed bugs in QGSJET cross section function when it was called with nuclear or meson primary. Fixed major bug in QGSJET-II cross section readout. qgsect supports only 3 types of primaries and not all the known particles.
  7. Cross section readout fixed for SIBYLL with meson primaries (where p.A is None)
  8. Implemented missing cross section readout for SIBYLL 2.1
  9. Some cosmetics and some imports sorted
