Local Packages
Made some significant changes to my buildsystem:
Used suggestions from Extras/MockTricks to enable the autocache of mock buildroots to speed up mock. It's interesting to see how much the size of the minimal buildroot (the packages listed at fedoraProject:Packaging/Guidelines#Exceptions plus their dependencies) changes between distributions:
$ ls -l /var/lib/mock/root-cache/ total 1915456 -rw-rw-r-- 1 root mock 81888007 Aug 24 11:42 centos-3-i386.tar.gz -rw-rw-r-- 1 root mock 85405813 Aug 24 11:54 centos-3-x86_64.tar.gz -rw-rw-r-- 1 root mock 121852773 Aug 24 11:40 centos-4-i386.tar.gz -rw-rw-r-- 1 root mock 128487310 Aug 24 11:52 centos-4-x86_64.tar.gz -rw-rw-r-- 1 root mock 89651706 Aug 24 11:31 fedora-1-i386-core.tar.gz -rw-rw-r-- 1 root mock 92763322 Aug 24 11:21 fedora-2-i386-core.tar.gz -rw-rw-r-- 1 root mock 130415162 Aug 24 11:11 fedora-3-i386-core.tar.gz -rw-rw-r-- 1 root mock 138236605 Aug 24 11:03 fedora-4-i386-core.tar.gz -rw-rw-r-- 1 root mock 143118349 Aug 24 11:58 fedora-4-x86_64-core.tar.gz -rw-rw-r-- 1 root mock 128570517 Aug 24 10:59 fedora-5-i386-core.tar.gz -rw-rw-r-- 1 root mock 132355621 Aug 24 12:06 fedora-5-x86_64-core.tar.gz -rw-rw-r-- 1 root mock 223028304 Aug 24 10:53 fedora-development-i386-core.tar.gz -rw-rw-r-- 1 root mock 229692899 Aug 24 10:40 fedora-development-x86_64-core.tar.gz -rw-rw-r-- 1 root mock 57085074 Aug 24 11:48 redhat-73-i386.tar.gz -rw-rw-r-- 1 root mock 86610677 Aug 24 11:46 redhat-8-i386.tar.gz -rw-rw-r-- 1 root mock 90143315 Aug 24 11:44 redhat-9-i386.tar.gz
Also from Extras/MockTricks, I set up a local squid cache. This isn't needed for any of the current distribution releases I'm building for since I keep local mirrors of those, but it enables me to build packages for rawhide without having to constantly re-download lots of large packages.
I made myself a wrapper script (mb) to run mock, so as to ensure that I don't forget to use the --autocache option or use setarch i386 for 32-bit builds. It also gives me a shorthand notation for the distributions, so I can do:
$ mb fc4.32 some.src.rpm $ mb fc4.64 some.src.rpm
and I'll get 32 and 64 bit builds for FC4
- Here's the script in case it's of any use to anyone (it'll need tweaking):
# mb: mock build # mb distro.archbits options ... # # e.g. # mb rhl7.32 rebuild some.rpm # mb fc5.64 rebuild some.rpm # How to use mb usage () { echo "mb: usage: mb distro.archbits options ..." } # Parse distro.archbits case "$#" in 0|1) usage 1>&2 exit 1;; *) root="$1" shift;; esac distro=${root/%.*/} archbits=${root/#*.} if [ "${distro}.${archbits}" != "$root" ]; then echo "mb: cannot parse distro.archbits: $root" 1>&2 exit 1 fi # Only valid values for archbits are 32 and 64 case "$archbits" in 32|64) ;; *) echo "mb: archbits should be 32 or 64: $archbits" exit 1;; esac # Only valid values for distro are rhl[7-9], rhel[3-4], fc[1-6] case "$distro" in rhl7|rhl8|rhl9) ;; rhel3|rhel4) ;; fc1|fc2|fc3|fc4|fc5|fc6) ;; *) echo "mb: valid distros are: rhl[7-9], rhel[3-4], fc[1-6]" 1>&2 exit 1;; esac # Work out buildroot name case "$root" in rhl7.32) buildroot=redhat-73-i386;; rhl8.32) buildroot=redhat-8-i386;; rhl9.32) buildroot=redhat-9-i386;; rhel3.32) buildroot=centos-3-i386;; rhel3.64) buildroot=centos-3-x86_64;; rhel4.32) buildroot=centos-4-i386;; rhel4.64) buildroot=centos-4-x86_64;; fc1.32) buildroot=fedora-1-i386-core;; fc2.32) buildroot=fedora-2-i386-core;; fc3.32) buildroot=fedora-3-i386-core;; fc4.32) buildroot=fedora-4-i386-core;; fc4.64) buildroot=fedora-4-x86_64-core;; fc5.32) buildroot=fedora-5-i386-core;; fc5.64) buildroot=fedora-5-x86_64-core;; fc6.32) buildroot=fedora-devel-i386-core;; fc6.64) buildroot=fedora-devel-x86_64-core;; *) echo "mb: unsupported distribution/architecture: $root" 1>&2 exit 1;; esac # Run mock case $archbits in 32) echo setarch i386 mock --autocache -r $buildroot "$@" setarch i386 mock --autocache -r $buildroot "$@";; 64) echo mock --autocache -r $buildroot "$@" mock --autocache -r $buildroot "$@";; esac Updated buildsys-macros to use the next major release version if the release version number extracted from /etc/redhat-release has a number larger than 80 after a decimal point. So for instance, building it on the current rawhide (FC 5.91) returns:
dist .fc6 fedora 6
