DESCRIPTION

       gbp buildpackage is used to build Debian source and .deb packages from a Git repository.

       gbp buildpackage will, in order:

       • Verify that it is being executed from the proper location.

       • Verify that the repository doesn't contain any uncommitted source changes.

       • Verify that it is being executed from the correct branch.

       • (Optionally) run a clean command specified with --git-cleaner.

       • (Optionally) export the source tree to a separate build area.

       • Build an orig tarball if it doesn't exist. Optionally using pristine-tar.

       • (Optionally) call a pre build hook.

       • Call debuild(1) or Cowbuilder (via --git-pbuilder)  or  the  application  specified  via
         --git-builder  passing along all arguments given to gbp buildpackage on the command line
         that don't start with --git-.

       • (Optionally) tag the current commit after a successful build.

       • (Optionally) call a post build hook - e.g. to run lintian.

       • (Optionally) call a post tag hook - e.g. to push the  results  to  a  remote  repository
         after creating the tag.

OPTIONS

All options are prefixed with git- to distinguish options for gbp buildpackage from
options passed to the BUILD_CMD:

UPSTREAM TARBALL CREATION OPTIONS
When gbp buildpackage doesn't find a suitable upstream tarball it will create one either
using pristine-tar or git archive. These options determine how the tarball is created:

--git-pristine-tar
Use pristine-tar when generating the upstream tarball if it doesn't exist. If this
mode is enabled the --git-upstream-tag, --git-upstream-tree options have no effect.

--git-upstream-tag=TAG-FORMAT
Use this tag format when looking for tags of upstream versions to build the
upstream tarballs. Default is upstream/%(version)s. This must be set correctly if
you don't want to pass any other options. The default matches what gbp import-orig
uses to create tags.

--git-upstream-tree=[BRANCH|SLOPPY|TAG|TREEISH]
How to find the upstream sources used to generate the tarball. TAG (the default)
looks at a tag corresponding to the version in the changelog. BRANCH looks at the
upstream branch given via the --git-upstream-branch option. The SLOPPY option looks
at the debian branch given via the --git-debian-branch and drops the debian/ dir.

Other values are interpreted as treeishs.

This doesn't have any effect if --git-pristine-tar is being used.

--git-upstream-branch=BRANCH_NAME
Branch to build the orig tarball from if --git-upstream-tree is set to BRANCH.
Default is upstream.

--git-tarball-dir=DIRECTORY
Search for upstream tarballs in DIRECTORY instead of generating them. If a tarball
is not found here it will be generated nevertheless.

--git-component=COMPONENT
When generating tarballs create an additional upstream tarball of directory
COMPONENT in the source tree. Using additional upstream tarballs is a feature of
the 3.0 (quilt) source format. See the dpkg-source manpage for details. Note that
the --git-pristine-tar-commit option is currently incompatible with this option.

This is considered an experimental feature and might change incompatibly.

--git-pristine-tar-commit
Commit the pristine-tar delta to the pristine-tar branch if a new tarball was
generated and the pristine-tar data isn't already there.

--git-force-create
Force creation of an upstream tarball (overwriting a pre-existing one if present).

--git-no-create-orig
Don't try to create any upstream tarballs or to create symlinks to existing
tarballs in tarball-dir.

--git-[no-]submodules
Include Git submodules in the orig tarball if present.

--git-compression=TYPE
Specifies the upstream tarball compression type. This will be used to locate and
build the upstream tarball if necessary. The default is auto which derives the
compression type from the pristine-tar branch if available and falls back to gzip
otherwise. Other options are gzip, bzip2, lzma and xz.

--git-compression-level=LEVEL
Specifies the upstream tarball compression level if an upstream tarball needs to be
built.

PACKAGE BUILD OPTIONS
gbp buildpackage can invoke different types of builders to produce the source and binary
packages. These options determine which builder is invoked and how.

--git-builder=BUILD_CMD
Use BUILD_CMD instead of debuild -i -I. If you want to use Cowbuilder or Pbuilder
see the --git-pbuilder.

--git-cleaner=CLEAN_CMD
Use CLEAN_CMD to clean the source tree before the build. The default is /bin/true
(no cleaning).

--git-pbuilder
Build the package using git-pbuilder (which uses cowbuilder by default). Note that
this overwrites any --git-builder and --git-cleaner options.

--git-qemubuilder
Build package using git-pbuilder with qemubuilder. Note that this overwrites any
--git-builder and --git-cleaner options.

--git-dist=DIST
Build for distribution DIST when using git-pbuilder (either via --git-pbuilder,
--git-qemubuilder or the corresponding configuration file options). If unset build
for the unstable distribution. The special value DEP14 will set the distribution to
build for from the branch name. I.e. if you're starting the build from a branch
named debian/wheezy-backports the distribution is set to wheezy-backports. If the
branch is named downstream/sid the distribution is set to downstream_sid.

--git-arch=ARCH
Build for architecture ARCH when using git-pbuilder (either via --git-pbuilder,
--git-qemubuilder or the corresponding configuration file options). If unset no
architecture is passed to git-pbuilder.

--git-pbuilder-autoconf
Whether to try to autoconfigure git-pbuilder or to rely on the settings in
.pbuilderrc. See the git-pbuilder manpage for details. Only takes effect when using
git-pbuilder (either via --git-pbuilder, --git-qemubuilder or the corresponding
configuration file options).

--git-pbuilder-options
Options to pass to pbuilder when building via git-pbuilder (either via
--git-pbuilder, --git-qemubuilder or the corresponding configuration file options).
It does so by using the GIT_PBUILDER_OPTIONS environment variable to pass options
to git-pbuilder.

As an example, to tell pbuilder to use an alternate .pbuilderrc file, you may run
gbp buildpackage with --git-pbuilder-options="--configfile /tmp/my/pbuilderrc". See
pbuilder(8) for more options to pass through here.

If unset the GIT_PBUILDER_OPTIONS environment variable will be left untouched.

--git-notify=[auto|on|off]
Whether to send a desktop notification after the build. This needs python3-notify2
installed.

HOOK OPTIONS
Hooks allow you to run arbitrary commands at different stages of the build. These options
configure what will be run:

--git-postexport=COMMAND
Execute COMMAND after exporting the source tree. Valid only if --git-export-dir has
been specified. The working directory of this hook is the toplevel directory of the
exported source tree.

Exported environment variables are: GBP_GIT_DIR (the repository the package is
being built from), GBP_TMP_DIR (the temporary directory where the sources have been
initially exported).

--git-prebuild=COMMAND
Execute COMMAND from the build directory before calling debuild or the application
specified via --git-builder.

Exported environment variables are: GBP_GIT_DIR (the repository the package is
being built from), GBP_BUILD_DIR (the build dir).

--git-postbuild=COMMAND
Execute COMMAND after successful build. The working directory of this hook is the
directory the package was built in.

Exported environment variables are: GBP_CHANGES_FILE (the name of the generated
changes file), GBP_BUILD_DIR (the build dir).

--git-posttag=COMMAND
Execute COMMAND after tagging a new version. The working directory of this hook is
the toplevel directory of the Git repository.

Exported environment variables are: GBP_TAG (the name of the generated tag),
GBP_BRANCH (the branch the package was build from) and GBP_SHA1 (the sha1 of the
commit the tag was created at).

--git-[no-]hooks
Enable running all (cleaner, postexport, prebuild, postbuild, and posttag) hooks.
Note: the --git-builder command is not affected by this option.

TAGGING OPTIONS
--git-tag
Add a git tag after a successful build. It tags the currently checked out commit
except when you're on a patch-queue branch. In that case the corresponding debian
branch is tagged.

This is a command line only option that cannot be specified via gbp.conf.

--git-[no-]sign-tags
GPG sign all created tags.

--git-keyid=GPG-KEYID
Use this keyid for gpg signing tags.

--git-debian-tag=TAG-FORMAT
Use this tag format when tagging Debian versions, default is debian/%(version)s.

--git-debian-tag-msg=tag-msg-format
Use this tag message format when signing Debian versions, default is %(pkg)s Debian
release %(version)s

--git-retag
Don't fail tag operations if a tag with the same version already exists. This is a
command line only option that cannot be specified via gbp.conf.

--git-tag-only
Don't build, only tag and run post-tag hooks. This is a command line only option
that cannot be specified via gbp.conf.

BUILD AREA OPTIONS
gbp buildpackage can export the source tree to a different build-area before performing
the build. This options specify if and how this is done:

--git-export-dir=DIRECTORY
Export the current branch head (or the treeish object given via --git-export to
DIRECTORY before building. If unset the source will not be exported before starting
the build.

--git-export=TREEISH
Instead of exporting the current branch head, export the treeish object TREEISH.
The special name INDEX exports the current index whereas the special name WC
exports the current working copy as is.

Note that using WC enables the --git-ignore-branch and --git-ignore-new options as
well since when exporting the working copy there's no point in enforcing any branch
or modification checks.

--git[-no]-purge
Purge (remove) temporary build area after build. This is the default but it can be
turned off for e.g. debugging purposes.

--git-[no-]overlay
Extract upstream tarball from tarball-dir when using the export-dir option (in
analogy to mergeWithUpstream in svn-bp). Also remove debian/ if contained in the
upstream tarball in case of 2.0 and 3.0 source formats.

This optios allows one to keep only the debian/ dir in the version control system.

SAFETY OPTIONS
In order to make sure what you build is what you upload gbp buildpackage performs several
safety checks. These options allow one to configure and disable them:

--git-debian-branch=BRANCH_NAME
If you're not on this branch when invoking gbp buildpackage it will fail. Default
is master. This is done to make sure you don't accidentally release from a topic
branch. Not being on this branch will be ignored when using --git-ignore-new.

--git-ignore-branch
Don't check if the current branch matches DEBIAN-BRANCH.

--git-[no-]ignore-new
Don't abort if there are uncommitted changes in the source tree or the current
branch doesn't match the DEBIAN-BRANCH.

COLOR AND VERBOSITY OPTIONS
--git-verbose
Verbose execution. Useful for debugging and bug reports.

--git-color=[auto|on|off]
Whether to use colored output.

--git-color-scheme=COLOR_SCHEME
Colors to use in output (when color is enabled). The format for COLOR_SCHEME is
'<debug>:<info>:<warning>:<error>'. Numerical values and color names are accepted,
empty fields imply the default color. For example --git-color-scheme='cyan:34::'
would show debug messages in cyan, info messages in blue and other messages in
default (i.e. warning and error messages in red).

EXAMPLES

       Build a Debian package using git-pbuilder  which  in  turn  invokes  cowbuilder.  Instruct
       cowbuilder to build within a Wheezy chroot for i386.

             gbp buildpackage --git-pbuilder --git-arch=i386 --git-dist=wheezy

       Note that the above needs a cowbuilder chroot already. This can be created using:

             DIST=wheezy ARCH=i386 git-pbuilder create

CONFIGURATION FILES

       Several  gbp.conf  files  are parsed to set defaults for the above command-line arguments.
       See the gbp.conf(5) manpage for details.

       All options in the config files must be specified  without  the  'git-'  prefix.  So  e.g.
       --git-debian-branch=debian/sid becomes in gbp.conf:

             [buildpackage]
             debian-branch = debian/sid
