Rahul Sundaram > described a way to check for unnecessary dependencies. I found that method > somewhat unwieldy Well, I develop a debian distribution for my organisation and I often need to confirm whether the packages in the repository are installable or not. I use edos-debcheck. Here is a sample invocation. deba...@deep-blue:/data/all/distros/deepofix-trunk/install_cd/deepofix/dists/doublethink/main/binary-i386$ edos-debcheck -failures -explain < Packages Parsing package file... 0.4 seconds 684 packages Generating constraints... 0.2 seconds libarchive-tar-perl (= 1.30-2): FAILED The following constraints cannot be satisfied: libarchive-tar-perl (= 1.30-2) conflicts with perl-modules (= 5.10.0-19) libarchive-tar-perl (= 1.30-2) depends on perl (>= 5.6.0-16) {perl (= 5.10.0-19)} perl (= 5.10.0-19) depends on perl-modules (>= 5.10.0-19) {perl-modules (= 5.10.0-19)} liblocale-maketext-simple-perl (= 0.12-2): FAILED The following constraints cannot be satisfied: liblocale-maketext-simple-perl (= 0.12-2) depends on liblocale-maketext-lexicon-perl {liblocale-maketext-lexicon-perl (= 0.66-1)} liblocale-maketext-simple-perl (= 0.12-2) conflicts with perl-modules (= 5.10.0-19) liblocale-maketext-lexicon-perl (= 0.66-1) depends on liblocale-maketext-perl {perl-modules (= 5.10.0-19)} libssp0 (= 4.1.1-21): FAILED The following constraints cannot be satisfied: libssp0 (= 4.1.1-21) depends on gcc-4.1-base (= 4.1.1-21) {NOT AVAILABLE} libversion-perl (= 0.6701-1): FAILED The following constraints cannot be satisfied: libversion-perl (= 0.6701-1) depends on perlapi-5.8.8 {NOT AVAILABLE} Checking packages... 0.3 seconds As you can see, it tells me which packages can not be installed due to dependency failure. It takes the Packages file metadata and processes it. For your particular case, where you want to check dependency tress for a particular package, I think that can be done too. "deba...@deep-blue:~$ edos-debcheck --help Usage: edos-debcheck [OPTION]... [PACKAGE]... Check whether the given packages can be installed. A binary package control file is read from the standard input. The names (for instance, 'emacsen') of the packages to be tested should be given on the command line. A specific version of a package can be selected by following the package name with an equals and the version of the package to test (for instance, 'xemacs21=21.4.17-1'). When no package name is provided, all packages in the control file are tested. Options: -check Double-check the results -explain Explain the results -rules Print generated rules -quiet do not emit warnings nor progress/timing info -failures Only show failures -successes Only show successes -help Display this list of options --help Display this list of options " Replace edos-debcheck with edos-rpmcheck. There is also an apt-cache flag that generates visual dependency graphs for a particular package. " dotty pkg(s) dotty takes a list of packages on the command line and generates output suitable for use by dotty from the GraphViz[1] package. The result will be a set of nodes and edges representing the relationships between the packages. By default the given packages will trace out all dependent packages; this can produce a very large graph. To limit the output to only the packages listed on the command line, set the APT::Cache::GivenOnly option. The resulting nodes will have several shapes; normal packages are boxes, pure provides are triangles, mixed provides are diamonds, missing packages are hexagons. Orange boxes mean recursion was stopped [leaf packages], blue lines are pre-depends, green lines are conflicts. " The above excerpt is from 'man apt-cache'. I am not sure if similar facility is available in yum. Caution, dotty cannot graph larger sets of packages. -- Regards, Debayan Banerjee Support Free Software http://deeproot.in -- fedora-devel-list mailing list fedora-devel-list@redhat.com https://www.redhat.com/mailman/listinfo/fedora-devel-list

Well, the security is dependent on the strength of the repository/package signature verification scheme. I am not sure how that is done exactly.

Re: Fedora 12: Emacs is not for software development
2009/11/28 Rahul Sundaram : > Why? It's just shows your personal preference for a editor. Emacs is > certainly not needed for software development. Well one does need an editor for development. Assuming vim and emacs have roughly equal user bases, chosing emacs over vim for the distribution shows Fedora packagers' personal preference too. I guess both vim and emacs should be available. -- Regards, Debayan Banerjee -- fedora-devel-list mailing list fedora-devel-list@redhat.com https://www.redhat.com/mailman/listinfo/fedora-devel-list
