Debian release to support

sbuild: lenny x86-64: can create 32 & 64 bit arch specific packages, ~12 in total:

  • Ubuntu LTS
  • last two Ubuntu releases
  • >=etch

Make check

  • use schroot to run "make check"

Problematic Packages

  • ATLAS (atlas-sage-x.y or version bump)
  • Python (python-sage-x.y or version bump)
  • jmol - potential conflict with gcj in stable (testing an above fine)
  • Maxima: copies mgnuplot script to libexec (Maxima is already in Debian)

Changelog

  • needs to be kept in sync with SPKG.txt (automated mechanism)
  • dch (Debian changelog)

Initially

  • webserver for static only content
  • set up apt-get repo on $SAGE.MATH
  • To set up repo: reprpro + gpg key for signing
  • domain: maybe "debian.sagemath.org" or "sagemath.org/debian"

Problem to be solved

  • Install location: /usr/share/sage/ - "sage" script in bin does cd and
    • then execute the appropriate sage scipt in /usr/share/sage/
  • location of tmp, i.e. TMP, /tmp or /var/tmp, not SAGE_ROOT/tmp

  • SAGE_ROOT/ipython - why is it there. What is the content (config files?)
  • databases in $SAGE_ROOT/data -> /use/share/sage/data

  • spkg directory: gone or moved to sage-dev.deb
  • make distclean: remove "*.c", "*.so", "*.os" in /devel/sage/
  • content of examples directory: What to do with the code?
  • LIB -> lib - Singular related, move to lib/Singular

  • text files from $SAGE_ROOT: /usr/share/doc/sage
  • create official Sage GPG key to sign packages

Package names

  • Comply with Debian policy when possible
  • libraries (for example NTL):
    • ntl_5.4.1-1.dsc (the source source package), tarball with debian directory
    • libntl0_5.4.1-1_i386.deb (initial NTL version, i.e. "0", contains shared library)
    • libntl-dev_5.4.1-1_i386.deb (headers & static libraries)

  • binary (eclib)
    • eclib_1.0_i386.deb (binaries)
    • libec0_1.0_i386.deb (shared libraries)
    • libec-dev_1.0_i386.deb (headers & static libraries)

  • Singular
    • To be determined

Setting up the build system (In Detail)

  • Start Debian installer
  • Partitioning method: "Guided - use entire disk and set up LVM" - accept defaults and write LVM init to disk
  • delete original main LVM volume, create new VG, say with 10GB
  • set up accounts for root and users as usual
  • update to lenny: edit /etc/apt/source and replace "etch" with "lenny"
  • "aptitude update"
  • "aptitude dist-upgrade" (wait a while :) )

  • download Tim's script collection from the main Deb packaging page [http://www.sagemath.org:9001/days7/DebianPackagingSprint?action=AttachFile (tarballs here for now)], untar ...

  • file "packages" contains list of packages needed for the build system
  • aptitude install cat packages installs the packages listed in packages

  • file "approx.conf.tail": append file to approx.conf - make sure to set a fast mirror, i.e. not the MIT repo
  • restart approx service via "/etc/init.d/approx restart"
  • edit make-chroot and set $VG to volume group name or export VG
  • Now create change roots for various targets using make-chroot: Parameters 1 is SUITE (i.e. lenny), 2 is ARCH (i.e. i386)

  • If things go wrong remove lvm group created :(

  • download Tim's other script collection from the main Deb packaging page [http://www.sagemath.org:9001/days7/DebianPackagingSprint?action=AttachFile (tarballs for now)], untar into /usr/local/bin ...

  • export DEBATHENA_APT=(path to SAGE apt repository)

To actually do builds

  • get SAGE .spkg and unpack into DIR
  • copy debian directory into $DIR/src
  • build source package using debuild -S from inside package directory ($DIR/src)
  • build binary packages using "da sbuildhack [resulting .dsc file]" from $DIR
  • upload into SAGE repository using "daupload-release [resulting .changes file]" from $DIR
  • use clean-schroots whenever you run out of disk space due to stale build chroots (often get leaked when you do ^C during a build)
