Hi all! With the help of TobiG I wrote a simple helper, for all those who need to update packages. Sometimes, as you all know, it's non-trivial to get all depencies or reverse depencies of a package - that's what this little helper will calculate for you.
If you upgrade a package, the script will be able to find out which packages you also need to rebuild/update. Also it gives you a hint (reverse depencies) about which packages might break after your upgrade. You should always investigate that listing, because if any package that's part of the buildenvironment depends on the package you're trying to upgrade, the update might result in a broken buildenvironment. You might consult TobiG or me in such cases ;) To use that script, you have to do the following: checkout the whole rpmlookup svn tree at $SVNROOT/yoper/projects/rpmlookup copy the file $SVNROOT/yoper/projects/rpmlookup/Default.cfg to your homedir at: ~/.yoperbuild/rpmlookup/Default.cfg Modify the contents of the file: cache: should point to a file location holding the svn spec cache (that's just used to speed up lookups) svndir: should point to the local svn working copy of the spec files, namely $SVNROOT/yoper, usually containing 3.0, 3.1, devel, playground, projects and "robots.text". Use path's only, no environment variables are supported. After that is done, you're ready for your first run of svnCacheLookup.py. The usage of that script should be self explanational. It does support the options "-r" and "-d", "-r" meaning calculate reverse depencies, "-d" depencies. E.g. running "svnCacheLookup.py -d bison" will result in the following output: [EMAIL PROTECTED] ~/svn/yoper/projects/rpmlookup $ ./svnCacheLookup.py -d bison building cache from /home/armin/svn/yoper/3.0/rocketfuel done package bison found at: /home/armin/svn/yoper/3.0/rocketfuel/bison/bison.spec /home/armin/svn/yoper/3.0/rocketfuel/texinfo/texinfo.spec /home/armin/svn/yoper/3.0/rocketfuel/pkg-config/pkg-config.spec /home/armin/svn/yoper/3.0/rocketfuel/e2fsprogs/e2fsprogs.spec /home/armin/svn/yoper/3.0/rocketfuel/linux-libc-headers/linux-libc-headers.spec /home/armin/svn/yoper/3.0/rocketfuel/flex/flex.spec /home/armin/svn/yoper/3.0/rocketfuel/diffutils/diffutils.spec /home/armin/svn/yoper/3.0/rocketfuel/gawk/gawk.spec /home/armin/svn/yoper/3.0/rocketfuel/autoconf/autoconf.spec /home/armin/svn/yoper/3.0/rocketfuel/automake/automake.spec /home/armin/svn/yoper/3.0/rocketfuel/automake16/automake16.spec /home/armin/svn/yoper/3.0/rocketfuel/libtool/libtool.spec /home/armin/svn/yoper/3.0/rocketfuel/gcc-opt/gcc-opt.spec /home/armin/svn/yoper/3.0/rocketfuel/gpm/gpm.spec /home/armin/svn/yoper/3.0/rocketfuel/ncurses/ncurses.spec /home/armin/svn/yoper/3.0/rocketfuel/readline/readline.spec /home/armin/svn/yoper/3.0/rocketfuel/gmp/gmp.spec /home/armin/svn/yoper/3.0/rocketfuel/which/which.spec /home/armin/svn/yoper/3.0/rocketfuel/binutils/binutils.spec /home/armin/svn/yoper/3.0/rocketfuel/yopermaintain/yopermaintain.spec /home/armin/svn/yoper/3.0/rocketfuel/gcc/gcc.spec /home/armin/svn/yoper/3.0/rocketfuel/m4/m4.spec /home/armin/svn/yoper/3.0/rocketfuel/bison/bison.spec Found 22 depencies You can also redirect the output to a file with the shell, only the paths are printed to stdout, all other output goes to stderr and is therefore leftout in normal redirection. Notice the direction of the output, it shows the package depending on the given package that's at the highest depth in the depency graph, meaning you should update packages in the exact order that's printed here. Another thing about what package names are supported: actually all. The internal cache of the script is built using all (sub-)package definitions and provides of a spec file, so e.g. calculating depencies of qt4-devel will in fact calculate those for qt4 instead. Keep that in mind. I hope that this little script is useful - TobiG and me will continue developing it much further.
