  4. Extensions for Multi-Platform Support XML Build System Wrapper • XML based build descriptions for multi-platform support • An automated GNU patchgeneration based on fixes to ETICS components, timestamped and stored for future patching. • Python based module, used as an interpreter for XML build descriptions, an intermediate patching system applied between checkout and builds, and table/report generation. Extra Utilities • Automated timestamped checkouts of ETICS configurations to be patched from the ETICS command-line interface. • Automatic RPM/deb to tarball generators in a form ready for integration into ETICS. • Python scripts used to create wiki tables showing differences between multiple build result files. Reporting • Automatic sync and storage of XML/HTML in a directory structure allowing automatic HTML table generation. • A Hypergraph generator using the ETICS XML results set

  5. Extended client directory structure etics update web-server Main: xml-etics-build ETICS client Command line Xml parsing patches <project> workspace Tarball creator bin timestamp auto- checkout Main extension ETICS DM DM-modules project-rules build-rules patches RPM/deb generator lib/lib64 Hyper- graphs auto- commit repository HTMLgen patches Project/ component LEGEND xml vendor patches python bash

  6. XML Based Build Structure build-rules.xml project-rules.xml WN-modules-3.2.0.xml WN-3.2.0.xml User runs commands like: $ ./xml-etics-build2 --dryrun --targets=“patch,build,publish” org.glite-workspace/WN-3.2.0.xml

  7. Build Results & Achievements • Building on CentOS 5.x/4.x (x86/x86_64), Debian 4.0/5.0 (x86_64), Mac OS X 10.5 (x86), Play Station 3 (PowerPC), openSUSE 11.1 (x86_64) • Local builds are way ahead of CERN for Debian 5.0 x86_64/x86 although all patches auto-generated with timestamps are applied locally and defined in CERN savannah bug tracking system. • Debian 5.0/4.0 x86_64 gLite-UI/WN and openSUSE 11.1 x86_64 glite-WN are ready for test. gLite-WN without DM is running on PS3 for local users drug screening software.

  8. Conclusions • TCD has been effectively using this software for 3-4 years now. • The software is much more well developed since presented in CGW’07. • The software is relatively easy to manage and provides a good framework for anyone using ETICS locally. • The patches generated at the local sites MUST be fed back by NGI’s to EGI. • Going forward, open source development/porting of grid middleware should be encouraged!
