| Abstract: |
The pipeline group at ESO has been delivering 20+ pipelines for the world-class
VLT/I telescope since several years with the goal of providing
an homogeneous user experience, minimise duplication of efforts and provide
flexibility to the individual project deadlines, all spread across
3+ millions lines of C/C++, python and java code. The use of shared components across the entire portfolio helps minimising
duplication of code and leverages common solutions, however this requires
an extra coordination effort. The VLT/I pipelines are deployed in a variety
of environments, ranging from high-end operational systems at the observatories
to scientist laptops. A novel in-house packaging system abstracts the details
for the different delivery scenarios helping the developers to concentrate on
their intentions while an automatic system acts on the different repositories
to achieve the end result. Currently we support rpm, macports and source
tarballs kits packaging systems, but the plugin-based design allows to add
other types of packages. |
