NAME

   git-pbuilder - Wrapper around cowbuilder/qemubuilder for gbp
   buildpackage

SYNOPSIS

   DIST=distribution ARCH=architecture [BUILDER=(pbuilder|qemubuilder)] \
       git-pbuilder debbuild-options

   DIST=distribution ARCH=architecture [BUILDER=(pbuilder|qemubuilder)] \
       git-pbuilder (update | create | login) cowbuilder-options

DESCRIPTION

   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.

ENVIRONMENT

   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_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".

FILES

   /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.
