NAME
backport-dsc - backport Debian source packages
SYNOPSIS
backport-dsc [OPTIONS] <dsc-file>
DESCRIPTION
Helper to aid backporting a Debian source package to an arbitrary distribution release.
backport-dsc aids backporting by appropriately mangling the source package version, adjusting the
maintainer of a package and compiling an informative changelog entry. Moreover, it supports distribution
specific patches (plain, or for format 3.0 (quilt) source packages) and allow modification of
debian/control via arbitrary 'sed' expressions.
Backport relevant patches can be embedded in source packages for use with backport-dsc. The distribution
name (see --target-distribution) serves as an identifier to search for patches in the source package that
shall be applied for a particular distribution. For packages using format the 3.0 (quilt), backport-dsc
will look for debian/patches/series-<distname> and append it to the main patch series. Moreover,
backport-dsc will also look for patches matching /debian/patches/<distname>-dsc-patch* and apply them to
the source package. The latter patches, unlike the former quilt series, can also be used to modify the
debian/ directory itself.
OPTIONS
-d <distname>, --target-distribution <distname>
Arbitrary distribution name (e.g. squeeze-backports). This will be the target distribution used
for the backport changelog entry. The distribution name also serves as an identifier to search for
backport patches in the source package.
-h, --help
Print short description, usage summary and option list.
--maint-email <email>
Specify the backport maintainer's email address. Alternatively, backport-dsc will use the DEBEMAIL
environment setting.
--maint-name <name>
Specify the backport maintainer's real name. Alternatively, backport-dsc will use the DEBFULLNAME
environment setting.
--mod-control <expression>
sed expression to modify debian/control. The option can be given multiple times and all
expressions will be passed to sed in the order of appearance. This can be used to, e.g. change
build or runtime dependencies.
--no-backport-patches
If set, potentially existing backport patches will not be applied/activated.
--no-colored
If set, backport-dsc won't colorize its status and error messages.
--no-maintainer-update
If set, the orginal maintainer is preserved in the backported source package. This should only be
done if original maintainer and backporter are identical. Otherwise the porter should take
responsibility for the source package backport and identify herself as the maintainer.
-s <string>, --version-suffix <string>
Version suffix that will be appended to the original source package version, ideally indicating
the backport target distribution. The resulting package version will follow this schema:
<originalversion><prefix><suffix>+<digit>
e.g.: 1.2.3-4~bpo60+1 with default <prefix>=~
-p <string>, --version-prefix <string>
Version prefix that will be prepended to the backport version.
By default it
is ~ but want to be changed (e.g. to +) for forward-porting to next releases.
--verbose
Enable additional status messages.
--verbose-help
Print all available help.
--version
Print version information and exit.
ENVIRONMENT
backport-dsc acknowledges the common environment variables DEBFULLNAME and DEBEMAIL to specify the
maintainer.
FILES
backport-dsc reads configuration from two files: system-wide from /etc/backports-dsc and per user
settings from $HOME/.backport-dsc (in that order). Both files have to be valid bash scripts that will be
sourced by backport-dsc. The following variables (each shown with an example setting) can be used to
pre-configure backport-dsc:
bp_distribution="squeeze-backports"
Backport target distribution (see --backport-distribution)
bp_version_prefix="~"
Version prefix (see --version-prefix)
bp_version_suffix="bpo60"
Version suffix (see --version-suffix)
bp_maintainer_name="Unknown fellow"
Name of the backport maintainer (see --maint-name)
bp_maintainer_email="user@example.net"
Email address of backport maintainer (see --maint-email)
bp_apply_patches=1
Whether or not to apply backport patches found in a source package. (see --no-backport-patches)
bp_color_output=1
Enable or disable colored status output (see --no-color)
bp_verbose=0
Enable verbose status output (see --verbose)
bp_mod_control="--mod-control 's/^Depends:.*$/&, mypackage/'"
sed expressions to modify debian/control, for example to add dependencies (see --mod-control)
bp_update_maintainer=1
Whether or not to replace the original maintainer in the backported source package (see
--no-maintainer-update)
EXAMPLES
backport-dsc examplepkg_1.2.3-4.dsc
Create backport suitable for backports.org
backport-dsc -d myown-backports -v mo2010 examplepkg_1.2.3-4.dsc
Create backport for some custom distribution with custom version suffix.
backport-dsc -d ubuntu-lucid -v myppa --mod-control "-e 's/iceweasel/firefox/g'" examplepkg_1.2.3-4.dsc
Create a backport for a fake Ubuntu PPA repository, replacing all occurrences of iceweasel in
debian/control with firefox.
