  1. AliRoot and AliEnBuild Integration and Testing System Alina Grigoras alina.gabriela.grigoras@cern.ch

  2. Have a current, up to date, installable binary image of AliEn and AliRoot for different architectures • Automate the process of building AliEn components and of AliRoot • Better understanding of the dependencies between packages • Perform functional and unit tests at build time and receive alerts immediately • Web interface that allows the monitoring of the build status and remote access to logs Purpose

  3. Currently we support for both AliEn and AliRoot • the following architectures: • SLC4 32 and 64 bits (soon to be discarded) • SLC5 32 and 64 bits • SLC4 Itanium • IntelMac 32 and 64 bits (32 soon to be discarded) • Ubuntu 64bits (for testing purpose) Supported architectures • AliEnBITS Web Interface Main Menu

  4. AliEn

  5. Current work • Updating key packages: • Globus Toolkit • Purpose: • Fixing a bug related to the recompilation of Gapi • having only one version of openssl • Issues: • Affecting a big number of packages including Gapi • Updating packages • Patching packages • Needs extra packages as requirements (JDK and ANT) • Apache WebServer • Purpose: fixing security issues raised by IT Security Dep. • Issues: affecting gridsite package, known to have building problems • Testing AliEn with the new packages • Adding features to the BuildServer itself • To be able to ignore at installation some packages, usually devel packages like ANT or JDK

  6. Current work • All the changes from previous slide must be applied and tested on all platforms • Issues: • Some packages are really old and they are not supported anymore • Rebuilding a distribution takes ~a couple of hours thus each iteration is slow • Problems are really difficult to spot • Packages that don't have a clear building and installation script • Because of the big number of packages and dependencies one change in a package can trigger a whole chain of problems • Some packages are not supported at all for some platforms, usually for Mac

  7. Future plans • Adding a gLite test environment, without installing gLite with AliEn (quite urgent) • Issues: installing gLite on all build servers independent of the build and testing process, certificates etc • Synchronizing the build number between different platforms (quite urgent) • You can have AliEn 2-17.23 for 32bits and AliEn 2-17.30 for 64bits • Major cleaning of AliEn packages (somewhere in the future)

  8. AliRoot • Usual work: Building and registering to AliEn different tags of AliRoot • Current work: • Implementing an automatic email alert system • If AliRoot fails, check where it failed and email the responsible persons about it • This applies only to the trunk, that is build every night • Future plans : automatically register packages to AliEn, now it is done using an intermediate MonAlisa webpage
