Description
The ATLAS software infrastructure facilitates efforts of more than 1000
developers working on the code base of 2200 packages with 4 million C++
and 1.4 million python lines. The ATLAS offline code management system is
the powerful, flexible framework for processing new package versions
requests, probing code changes in the Nightly Build System, migration to
new platforms and compilers, deployment of production releases for
worldwide access and supporting physicists with tools and interfaces for
efficient software use. It maintains multi-stream, parallel development
environment with about 70 multi-platform branches of nightly releases and
provides vast opportunities for testing new packages, for verifying
patches to existing software and for migrating to new platforms and
compilers. The system evolution is currently aimed on the adoption of
modern continuous integration (CI) practices focused on building nightly
releases early and often, with rigorous unit and integration testing. This
presentation describes the CI incorporation program for the ATLAS software
infrastructure. It brings modern open source tools such as Jenkins and
CTest into the ATLAS Nightly System, rationalizes hardware resource
allocation and administrative operations, provides improved feedback and
means to fix broken builds promptly for developers. Once adopted, ATLAS CI
practices will improve and accelerate innovation cycles and result in
increased confidence in new software deployments. The presentation reports
the status of Jenkins integration with the ATLAS Nightly System as well as
short and long term plans for the incorporation of CI practices.
