git-pbuilder is a wrapper around pdebuild intended for use by gbp buildpackage. It configures pdebuild to use cowbuilder by default, passes appropriate options to debbuild, and sets the base path for cowbuilder based on the environment variable DIST and, if set, the environment variable ARCH. qemubuilder can be selected instead by setting the environment variable BUILDER to "qemubuilder", and pbuilder can be selected by setting BUILDER to "pbuilder". By default, git-pbuilder assumes the target distribution is "sid", the same architecture as the cowbuilder default, and uses /var/cache/pbuilder/base-sid.cow if it exists. If it doesn't, /var/cache/pbuilder/base.cow is tried. If DIST is set, its value is the target distribution and /var/cache/pbuilder/base-dist.cow is used instead. If DIST is "etch" or "ebo", --debian-etch-workaround is also passed to cowbuilder. If ARCH is set, its value is the target architecture and /var/cache/pbuilder/base-dist-arch.cow is used, with dist being set to "sid" if DIST was not set. If qemubuilder is used as the builder, no base directory is used. Instead, qemubuilder is invoked with the --config option pointing to the file /var/cache/pbuilder/qemubuilder-arch-dist.conf If pbuilder is used as the builder, git-pbuilder instead looks for /var/cache/pbuilder/base-sid.tgz by default and /var/cache/pbuilder/base.tgz if it doesn't exist. If DIST or ARCH are set, they are used to form the expected name of the tgz file in the same way as they're used to form the expected base directory for cowbuilder. Similar to cowbuilder, --debian-etch-workaround is passed to pbuilder if from the DIST setting it looks like the target distribution is etch. If git-pbuilder is invoked via a name that starts with "git-*-", the part between the hyphens is taken to be the default name of the builder to use. However, "pbuilder" is mapped to cowbuilder for backward compatibility; if you want to use pbuilder, you have to explicitly set BUILDER. The part after the last hyphen is taken to be the default distribution (if it contains no additional hyphen) or the default distribution followed by the default architecture (if it contains a hyphen). One can therefore create symlinks like "git-pbuilder-squeeze" pointing to git-pbuilder and use that name when wanting to use a distribution of "squeeze", or "git-qemubuilder-sid-armel" to use qemubuilder to build for the "armel" architecture and the "sid" distribution. Explicit settings of BUILDER, DIST, or ARCH always override any guesses from the command name. (But note that gbp buildpackage does not pass on environment variables when run with --git-pbuilder; see below.) Any arguments are passed as-is to dpkg-buildpackage via the --debbuildopts option to pdebuild. To pass arguments to the builder instead, put them in the environment variable GIT_PBUILDER_OPTIONS. To disable all attempts to discover the base path, tarball, or configuration file and set up the pbuilder options and instead rely on the settings in .pbuilderrc, set GIT_PBUILDER_AUTOCONF to "no". Normally, one does not run this script directly. Instead, it's used as the builder script for gbp buildpackage via the --git-pbuilder command-line option. When run this way, you should use the --git-dist, --git-arch, --git-qemubuilder, --git-pbuilder-autoconf, and --git-pbuilder-options flags instead of setting the DIST, ARCH, BUILDER, GIT_PBUILDER_AUTOCONF, and GIT_PBUILDER_OPTIONS environment variables. See gbp-buildpackage(1) for more information. Alternately, git-pbuilder may be called with an argument of "update", "create", or "login". In this case, it calls cowbuilder (or the configured builder as described above) using sudo and passes the corresponding command to the builder, using the same logic as above to determine the base directory and distribution. If the distribution (set in DIST) ends in "-backports", one of the following will be added as an --othermirror parameter to the builder: deb http://ftp.debian.org/debian $DIST main deb http://backports.debian.org/debian-backports $DIST main The first will be used for most distributions, and the second for "squeeze-backports". If the distribution ends in "-lts", the following will be added as an --othermirror parameter to the builder: deb http://ftp.debian.org/debian $DIST main to support building for Long Term Support releases. Any additional arguments to git-pbuilder are passed along to the builder. Due to how sudo works, invoking the builder with an action will not read the user's .pbuilderrc by default, so in this case git-pbuilder will add an explicit --configfile option pointing to the user's .pbuilderrc if it exists. If you use git-pbuilder with one of these arguments, you must have the "sudo" package installed, and you must configure sudo to let the current user run the appropriate builder command.
ARCH Sets the target architecture. For a cowbuilder builder, this sets both the base path and is passed as the --architecture option. With qemubuilder, this controls the path to the configuration file. With pbuilder, this sets the tgz path and is passed as --architecture. BUILDER Sets the builder to use. The only supported settings are "cowbuilder" (the default), "qemubuilder", and "pbuilder". COWBUILDER_BASE Set this environment variable to change the default location for the cowbuilder base directories (/var/cache/pbuilder). DIST Sets the target distribution. This is used primarily to determine the base path for cowbuilder or pbuilder or the configuration file path for qemubuilder, but it's also used to determine whether to pass --debian-etch-workaround to cowbuilder or pbuilder. GIT_PBUILDER_AUTOCONF If set to "no", disable the logic that constructs the base path, tarball, or configuration file and all other logic to determine the options to pass to the builder. Instead, just run the configured builder and assume its configuration is handled elsewhere (such as in .pbuilderrc). This also suppresses setting --buildresult, so the user will need to ensure that the configuration still puts packages where gbp buildpackage expects them. GIT_PBUILDER_DEBUG Set this environment variable to get additional debugging output like how cowbuilder is invoked. GIT_PBUILDER_OPTIONS Add additional options for the builder. These options are passed as-is to cowbuilder, qemubuilder, or pbuilder via pdebuild. The contents of this variable will undergo shell expansion, so any arguments containing shell metacharacters or whitespace need to be quoted in the value of the environment variable. GIT_PBUILDER_OUTPUT_DIR Where to put the result of the build. The default is ".." (the parent directory). This setting is ignored if GIT_PBUILDER_AUTOCONF is set to "no". GIT_PBUILDER_PDEBUILDOPTIONS Add additional options for pdebuild itself (such as --use-pdebuild-internal). The contents of this variable will undergo shell expansion, so any arguments containing shell metacharacters or whitespace need to be quoted in the value of the environment variable. PBUILDER_BASE Set this environment variable to change the default location for the pbuilder tgz files (/var/cache/pbuilder) when BUILDER is set to "pbuilder".
/var/cache/pbuilder/base-sid.cow /var/cache/pbuilder/base.cow The default "cowbuilder --basepath" directories, searched for in that order, if neither DIST nor ARCH is set. /var/cache/pbuilder/base-sid-$ARCH.cow The "cowbuilder --basepath" directory used if ARCH is set and DIST is not set. /var/cache/pbuilder/base-$DIST.cow The "cowbuilder --basepath" directory used if DIST is set and ARCH is not. /var/cache/pbuilder/base-$DIST-$ARCH.cow The "cowbuilder --basepath" directory used if DIST and ARCH are both set. /var/cache/pbuilder/base-sid.tgz /var/cache/pbuilder/base.tgz /var/cache/pbuilder/base-sid-$ARCH.tgz /var/cache/pbuilder/base-$DIST.tgz /var/cache/pbuilder/base-$DIST-$ARCH.tgz Similar to the above, the "pbuilder --basetgz" path used for various settings of DIST and ARCH if BUILDER is set to "pbuilder". /var/cache/pbuilder/qemubuilder-$ARCH-$DIST.conf The "qemubuilder --config" file used. $ARCH defaults to "armel" and $DIST defaults to "sid" if not set.
