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.

--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-posttag=COMMAND

Execute COMMAND after tagging a new version.

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-postbuild=COMMAND

Execute COMMAND after successful build.

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

--git-postexport=COMMAND

Execute COMMAND after exporting the source tree - valid only if --git-export-dir has been specified.

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-[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-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
