Efficient Package Version Management in CDB for Enhanced Software Distribution

This system allows users to easily include default package versions in templates stored centrally. Changing default versions requires updating only one place, streamlining workflows. Utilize functions like pkg_add, pkg_repl, and pkg_del with specified arguments. Manage default values for versions and architectures efficiently. Automate template creation with RPMGetDefault.pl tool. Ensure accurate RPM splitting and version checks for software distribution tasks.

  1. Package functions and tools in CDB Veronique LefebureGerman Cancio ELFms meeting 01.02.05

  2. Idea • Give the possibility to include the default version of a package in a template • The default versions are centrally stored in a separate template • When the default version is changed (security upgrade, …): it is changed at one single place • See Savannah bug 5424 (04.11.04)

  3. PAN functions • Pkg_add, pkg_repl, pkg_del: • Arguments: • <name> <version> <arch> <multi> • Now “DEF” is a possible value for <version> and for <arch> • The default values are found in pro_software_packages_defaults_<os>.tpl

  4. Pro_software_packages_defaults_<os>.tpl • Define variable package_default = nlist(“name1”,list(“version1”,”arch1”),….“nameN”,list(“versionN”,”archN”) );

  5. RPMGetDefault.pl • Creates pro_software_packages_defaults_<os>.tpl • `rpm -qp --nosignature --queryformat '%{NAME} %{VERSION}-%{RELEASE} %{ARCH}' $Source/$pack` • $Source = (configurable) • /afs/cern.ch/project/linux/cern/<os>/<arch>/Redhat/RPMS • /afs/cern.ch/project/linux/cern/updates/<arch>/RPMS

  6. Manual steps left • CDB commit the new pro_sw_pkg_defaults_<os>.tpl • Check for new splitting of RPMs • Check (?) for hardcoded RPM versions
