NAME

       sbuild.conf - configuration file for sbuild

DESCRIPTION

       sbuild.conf  is  a  Perl script which is sourced by sbuild to permit configuration.  It is
       run in a sandbox and restricted to setting a small number of  variables,  detailed  below,
       which  may  be  set  to  configure the behaviour of sbuild.  Each variable has an internal
       name, shown in all caps, and a perl variable showing the default setting.  Note  that  the
       internal  name  is  not  accessible within sbuild.conf; only the variable may be assigned.
       Also note that some of the defaults are set to be unique for each build, and  so  some  of
       the  defaults  shown here are unique to the user and system used to build sbuild, and will
       be different for your system.

       While sbuild permits many aspects of its behaviour  to  be  configured,  this  should  not
       normally  be  required.  The defaults should be adequate for most uses, and should only be
       changed if you are doing something more advanced, or have specialist requirements.

              --arch
              --build

              build_arch = ...;

       BUILD_ARCH_ALL
              BOOL type.  Build architecture: all packages by default.

              Related sbuild(1) command line options:

              --arch-all
              --no-arch-all

              Related sbuild(1) command line options:

              --arch-any
              --no-arch-any

              Default:

              $build_arch_any = 1;

       BUILD_ENV_CMND
              STRING type.  This command is run with the dpkg-buildpackage command line passed to
              it (in the chroot, if doing a chrooted build).  It is  used  by  the  sparc  buildd
              (which  is  sparc64)  to call the wrapper script that sets the environment to sparc
              (32-bit).  It could be used for other build environment setup scripts.   Note  that
              this is superseded by schroot's 'command-prefix' option

              Default:

              $build_env_cmnd = '';

       BUILD_PATH
              STRING  type.   By  default  the package is built in a path of the following format
              /build/packagename-XXXXXX/packagename-version/  where  XXXXXX  is  a  random  ascii
              string.  This option allows one to specify a custom path where the package is built
              inside the chroot. The sbuild user in the chroot must have  permissions  to  create
              the  path.  Common  writable  locations are subdirectories of /tmp or /build. Using
              /tmp might be dangerous, because (depending on the chroot backend) the /tmp  inside
              the  chroot  might  be  a world writable location that can be accessed by processes
              outside the chroot. The directory /build can only be accessed by  the  sbuild  user
              and  group  and should be a safe location. The buildpath must be an empty directory
              because the last component of the path will be removed after the build is finished.
              Notice  that  depending  on  the  chroot  backend (see CHROOT_MODE), some locations
              inside the chroot might be bind mounts that are shared with other sbuild instances.
              You  must  avoid  using  these  shared  locations  as  the  build path or otherwise
              concurrent runs of sbuild  will  likely  fail.  With  the  default  schroot  chroot
              backend,  the directory /build is shared between multiple schroot sessions. You can
              change this behaviour in /etc/schroot/sbuild/fstab. The behaviour of  other  chroot
              backends will vary.

              --build-path

              Default:

              $build_path = undef;

       BUILD_PROFILES
              STRING type.  Build profiles. Separated by spaces.

              Related sbuild(1) command line options:

              --profiles

              Default:

              $build_profiles = '';

       BUILD_SOURCE
              BOOL  type.  By default, do not build a source package (binary only build).  Set to
              1 to force creation of a source package, but note that this  is  inappropriate  for
              binary NMUs, where the option will always be disabled.

              Related sbuild(1) command line options:

              -s
              --source
              --no-source

              Default:

              $build_source = 0;

       CHECK_SPACE
              BOOL  type.   Check free disk space prior to starting a build.  sbuild requires the
              free space to be at least twice the size of the unpacked sources to allow  a  build
              to  proceed.   Can  be disabled to allow building if space is very limited, but the
              threshold to abort a build has been exceeded despite there being  sufficient  space
              for the build to complete.

              Default:

              $check_space = 1;

       CLEAN_SOURCE
              BOOL  type.   When  running  sbuild  from  within  an unpacked source tree, run the
              'clean' target before generating the source package. This might require some of the
              build  dependencies necessary for running the 'clean' target to be installed on the
              host machine. Only disable if you start from a clean checkout and you know what you
              are doing.

              $clean_source = 1;

       DISTRIBUTION
              STRING  type.   Default  distribution.  By default, no distribution is defined, and
              the user must specify it with the -d option.  However, a default may be  configured
              here if desired.  Users must take care not to upload to the wrong distribution when
              this option is set, for example experimental packages will be built for  upload  to
              unstable when this is not what is required.

              $distribution = undef;

       FORCE_ORIG_SOURCE
              BOOL  type.   By  default, the -s option only includes the .orig.tar.gz when needed
              (i.e. when the Debian revision is 0 or 1).   By  setting  this  option  to  1,  the
              .orig.tar.gz will always be included when -s is used.

       TOOLCHAIN_REGEX
              ARRAY:STRING  type.  Regular expressions identifying toolchain packages.  Note that
              for backward compatibility, this is also settable using the array  @toolchain_regex
              (deprecated), rather than an array reference.

              Default:

   Build timeouts
       INDIVIDUAL_STALLED_PKG_TIMEOUT
              HASH:NUMERIC  type.  Some packages may exceed the general timeout (e.g. redirecting
              output to a file) and need a different timeout.  This  has  is  a  mapping  between
              source  package  name  and  timeout.  Note that for backward compatibility, this is
              also settable using the hash %individual_stalled_pkg_timeout (deprecated) ,  rather
              than a hash reference.

              Example:

              %individual_stalled_pkg_timeout = (smalleiffel => 300,
                                     jade => 300,

       LOCK_INTERVAL
              NUMERIC type.  Lock wait interval (seconds).  Maximum wait time is (max_lock_trys x
              lock_interval).

              Default:

              $lock_interval = 5;

       MAX_LOCK_TRYS
              NUMERIC type.  Number of times to try waiting for a lock.

       STALLED_PKG_TIMEOUT
              NUMERIC type.  Time (in minutes) of inactivity after which a build  is  terminated.
              Activity is measured by output to the log file.

              Default:

              $stalled_pkg_timeout = 150;

              BOOL  type.   Force  APT  to  accept   unauthenticated   packages.    By   default,
              unauthenticated  packages  are  not allowed.  This is to keep the build environment
              secure, using apt-secure(8).  By setting this to 1,  APT::Get::AllowUnauthenticated
              is  set to "true" when running apt-get. This is disabled by default: only enable it
              if you know what you are doing.

              apt repository, the repository for extra  packages  (see  EXTRA_PACKAGES)  and  the
              repositories  given  via  EXTRA_REPOSITORIES.  These are always updated. Thus, this
              option only influences updates of the default repositories of the chroot.

              0  to  disable and do a full apt update (not recommended in case the mirror content
              has changed since the build started).

              Default:

       APT_UPGRADE
              BOOL type.  APT upgrade.  1 to enable running "apt-get upgrade"  at  the  start  of

       CHROOT_SPLIT
              BOOL type.  Run in split mode?  In split mode, apt-get and dpkg are run on the host
              system, rather than inside the chroot.

              Default:

       EXTERNAL_COMMANDS
              HASH:ARRAY:STRING  type.   External  commands  to run at various stages of a build.

              Default:

              $package_checklist = '/var/lib/sbuild/package-checklist';

       PURGE_BUILD_DEPS
              STRING type.  When to purge the build dependencies after a build;  possible  values
              are "never", "successful", and "always"

              Related sbuild(1) command line options:

       PURGE_BUILD_DIRECTORY
              STRING  type.  When to purge the build directory after a build; possible values are
              "never", "successful", and "always"

              $purge_build_directory = 'always';

       PURGE_EXTRA_PACKAGES
              BOOL type.  Try to remove all additional packages that are  not  strictly  required
              for  the  build right after build dependencies were installed. This currently works
              best with the aspcud resolver. The apt resolver will not make  as  much  effort  to
              remove  all  unneeded packages and will keep all providers of a virtual package and
              all packages from any dependency alternative  that  happen  to  be  installed.  The
              aptitude  and xapt resolver do not implement this feature yet. The removed packages
              are not yet added again after the build finished. This can  have  undesirable  side
              effects  like  lintian  not  working  (because  there  is  no  apt  to  install its
              dependencies) or bare chroots becoming totally unusable after apt was removed  from
              them.  Thus,  this  option should only be used with throw-away chroots like schroot
              provides them where the original state is automatically restored after each build.

       PURGE_SESSION
              STRING type.  Purge the schroot session following  a  build.   This  is  useful  in
              conjunction  with the --purge and --purge-deps options when using snapshot chroots,
              since by default the  snapshot  will  be  deleted.  Possible  values  are  "always"
              (default), "never", and "successful"

   Core options
       ARCHIVE
              STRING  type.   Archive  being built.  Only set in build log.  This might be useful
              for derivative distributions.

              -b
              --batch

              Default:

              $batch_mode = 0;

       BUILD_DIR
              STRING type.  This option is deprecated.  Directory for chroot symlinks and  sbuild
              logs.   Defaults  to  the  current  directory  if  unspecified.   It is used as the
              location of chroot symlinks (obsolete) and for current build log symlinks and  some
              build  logs.   There  is  no  default; if unset, it defaults to the current working
              directory.  $HOME/build is another common configuration.

              Example:

              $build_dir = '/home/pete/build';

              build_dir = ...;

       BUILD_ENVIRONMENT
              HASH:STRING type.  Environment to set during the build.  Defaults to  setting  PATH
              and LD_LIBRARY_PATH only.  Note that these environment variables are not subject to
              filtering with ENVIRONMENT_FILTER.  Example:

              Example:

                      'CCACHE_DIR' => '/build/cache'
              };

              Default:

              $build_environment = {};

       BUILD_USER
              STRING type.  Username used for running  dpkg-buildpackage.  By  default  the  user
              running  sbuild  is  used  within the chroot as well but that might allow a process
              from within the chroot to break out of the chroot by attaching to a process running
              outside  the  chroot  with eg. gdb and then becoming root inside the chroot through
              schroot and thus be able to leave the chroot.

              build_user = ...;

       CORE_DEPENDS
              ARRAY:STRING type.  Packages which must be installed in the chroot for all builds.

       ENVIRONMENT_FILTER
              ARRAY:STRING  type.   Only  environment  variables  matching  one  of  the  regular
              expressions in this arrayref will be passed to dpkg-buildpackage and other programs
              run by sbuild. The default value for this configuration  setting  is  the  list  of
              variable names as returned by Dpkg::Build::Info::get_build_env_whitelist() which is
              also the list of variable names that is whitelisted to be  recorded  in  .buildinfo
              files.  Caution:  the  default  value listed below was retrieved from the dpkg Perl
              library version available when this man page was generated. It might  be  different
              if your dpkg Perl library version differs.

   Dependency resolution
       ASPCUD_CRITERIA
              STRING type.  Optimization criteria in extended MISC 2012 syntax passed  to  aspcud
              through  apt-cudf.   Optimization  criteria  are  separated  by  commas,  sorted by
              decreasing order of priority and are prefixed with a polarity (+ to maximize and  -
              to  minimize).   The  default  criteria  is  '-removed,-changed,-new'  which  first
              minimizes the number of removed packages, then the number of changed  packages  (up
              or  downgrades)  and  then the number of new packages. A common task is to minimize
              the number of packages from experimental.  To do this you can add a  criteria  like
              '-count(solution,APT-Release:=/a=experimental/)'  to  the  default  criteria.  This
              will then minimize the number of packages in the solution which contain the  string
              'a=experimental'  in the 'APT-Release' field of the EDSP output created by apt. See
              the apt-cudf man page help on the --criteria option for more information.

       BUILD_DEP_RESOLVER
              STRING type.  Build dependency resolver.   The  'apt'  resolver  is  currently  the
              default,  and  recommended  for  most users.  This resolver uses apt-get to resolve
              dependencies.  Alternative resolvers are 'apt', 'aptitude' and 'aspcud'. The  'apt'
              resolver  uses  a  built-in  resolver  module  while  the  'aptitude' resolver uses
              aptitude to resolve build dependencies.  The aptitude resolver is similar  to  apt,
              but  is useful in more complex situations, such as where multiple distributions are
              required, for example when building from experimental, where  packages  are  needed
              from  both unstable and experimental, but defaulting to unstable. If the dependency
              situation is too complex for either apt or aptitude to solve it, you  can  use  the
              'aspcud'  resolver which (in contrast to apt and aptitude) is a real solver (in the
              math sense) and will thus always find a solution if a solution exists.

       RESOLVE_ALTERNATIVES
              BOOL type.  Should the  dependency  resolver  use  alternatives  in  Build-Depends,
              Build-Depends-Arch and Build-Depends-Indep?  By default, using 'apt' resolver, only
              the first alternative will be used; all other alternatives will be  removed.   When
              using  the  'aptitude'  resolver,  it will default to using all alternatives.  Note
              that this does not include architecture-specific alternatives, which are reduced to
              the build architecture prior to alternatives removal.  This should be left disabled
              when building for unstable; it may be useful  when  building  for  experimental  or
              backports.  Set to undef to use the default, 1 to enable, or 0 to disable.
