NAME
cvs-buildpackage - build Debian packages from a CVS repository.
SYNOPSIS
cvs-buildpackage [options]
DESCRIPTION
This manual page explains the Debian cvs-buildpackage utility, which is used to build Debian packages
whose sources are stored in a CVS repository. This is a CVS -aware wrapper around dpkg-buildpackage, and
it first parses ./debian/changelog; exports the corresponding version (tagged debian_version_<$version>
), and runs dpkg-buildpackage in the exported tree. It looks for uncommitted files in the source tree,
and offers to abort before doing anything so that the user may commit the files in, if they wish.
cvs-buildpackage can also optionally automatically re-tag all files before exporting the source (this
functionality is only relevant in the top level directory of a checked out Debian package source tree, of
course).
Please note that the work directory referred to below is the scratch directory where the program does its
work; it is where it shall export the sources from CVS, and it assumes full control of that directory
Read: anything in that directory, apart from the orig source files, can be deleted by cvs-buildpackage
Make sure not to have your checked out sources/working directory in the same location, as you may lose
data.
If this utility is not run from a top level directory of a checked out Debian package source tree, then
to build an old version the cvs module name or the package name have to be supplied on the command line.
Combined with the companion utilities cvs-inject and cvs-upgrade, this provides an infrastructure to
facilitate the use of CVS by Debian maintainers. This allows one to keep separate CVS branches of a
package for stable, unstable, and possibly experimental distributions, along with the other benefits of a
version control system.
OPTIONS
-h Print out a usage message.
-M<module>
The name of the CVS module.
-P<package>
Sets the name of the package. Very useful if this is not running in the CVS checked out source
tree, in which case one also needs the version of the package, which may optionally be determined
by checking out the latest debian/changelog file.
-V<version>
The version number of the package. In conjunction with setting the package name, this option
allows operation outside a CVS source tree (just needs the repository).
-T<tag>
The CVS tag to use for exporting sources, rather than constructing one from the version. This
assumes you know what you are doing.
-U<tag>
The CVS tag to use for the upstream tag, rather than constructing one from the upstream version.
This assumes you know what you are doing.
-C<Build Command>
Sets the name of the builder program invoked, nominally set to dpkg-buildpackage. However, the
user may choose to use a different build program, or a wrapper, or even 'chroot /opt/root dpkg-
buildpackage' to build the package in a chroot jail, if desired. (Obviously, this requires that
the Work directory to be a subdirectory of a previously set up chroot jail). One may also hook in
pbuilder by setting this variable to 'pdebuild --auto-debsign --buildresult ../'. (Again, this
requires that pbuilder has been set up correctly). This argument overrides the settings in the
environment variable CVSDEB_BUILDPACKAGE, and the configuration file variable conf_buildpackage.
-G<get method>
This option, if set, should contain a command to execute to get the original tarball into the
current directory. This can then be used to allow one to get the original file using, for
instance, wget or curl. This overrides the CVSDEB_GET_ORIG environment variable and the
conf_get_orig configuration file option.
-A Use apt-get source to retrive the original tarball. This option has no effect unless a source
package with the correct upstream version has already been uploaded and is referenced from a
Sources file known to apt. If -A and -G are both given, -G is tried first, and apt is used only
if that did not produce the tarball. This overrides the CVSDEB_USE_APT environment variable and
the conf_use_apt configuration file option.
-R<root directory>
Root of the original sources archive. We expect to find the <package name>_<version>.orig.tar.gz
file under <root directory>/package name>/ unless the cvs-buildpackage work directory has been
set, or we want to export the original sources from the vendor branch of the CVS tree. If the cvs-
buildpackage work directory is set anywhere, (command line, configuration file, environment
variable), the root directory value is ignored, since we only need the root directory to set
defaults for the cvs-buildpackage work directory. This argument overrides the settings in the
environment variable CVSDEB_ROOTDIR, and the configuration file variable conf_rootdir. Please
note that the cvs-buildpackage work directory referred to here is the scratch directory where this
program works, not the directory that the human uses to work in. This should probably not be a
sub dir of CVSROOT, since cvs shall refuse to export packages there, and the script shall fail.
-W<work directory>
The full path name for the cvs-buildpackage working directory, into which the sources will be
exported out of CVS and which should contain the original <package name>_<version>.orig.tar.gz
Please note that it is not strictly essential to have the original sources, as this script will
check out the vendor branch version tagged as upstream_version_<version> (without the Debian
revision). However, these recreated original sources are likely to be different for consecutive
runs of cvs-buildpackage, and very likely to be different from the pristine original sources
(different enough to cause problems with an upload). Thus it is strongly advisable to keep the
orig.tar.gz file around. Setting this variable overrides the settings for the root directory.
This argument also overrides the settings in the environment variable CVSDEB_WORKDIR, and the
configuration file variable conf_workdir. Please note that the cvs-buildpackage work directory
referred to here is the scratch directory where this program works, not the directory that the
human uses to work in. Also, you should specify an absolute path name for the work directory.
This should probably not be a sub dir of CVSROOT, since cvs shall refuse to export packages there,
and the script shall fail.
-F The Force Tag option. This only has effect if run in the source directory. If set, it forces a cvs
tag -F operation to be performed before exporting the sources. This argument overrides the
settings in the environment variable CVSDEB_FORCETAG, and the configuration file variable
conf_forcetag. The default action is not to force a tag before export.
-E The Full Export option. Normally, cvs-buildpackage will export all the data from CVS using cvs
export. If the orig.tar.gz is not available in the working directory, the full tree will be
exported from CVS regardless of whether this option is set or not. This option overrides the
environment variable CVSDEB_FULLEXPORT, and the configuration file variable conf_fullexport.
-op The opposite of full export. Using this option resets the value of full export. Normally, cvs-
buildpackage will export all the data from CVS using cvs export. With this option set, cvs-
buildpackage will extract the orig.tar.gz in the cvs-buildpackage working directory, and then use
the cvs rdiff command to bring that tree up-to-date with the CVS tree we're building. Please look
at the -f<fix_script> option to see how to massage the source tree after extraction and patching.
-ctp Include package_ at the start of the CVS tag. This overrides the CVSDEB_PACKAGEINTAG environment
variable and the conf_forcetag configuration file option. The default is not to include the
prefix.
-n The no exec (or dry-run) option, causing cvs-buildpackage to print out all actions that would be
taken without actually executing them.
-f<fix_script>
This option, if set, should point to a script that should be run just from the top level of the
source tree to set up permissions of scripts that have been created by pathching the sources from
an recently extracted original tar file (the behaviour attained by setting the -op option. This
script is called with two arguments, the package name, and version. This script is only relevant
when that option has been used. There a number of variables that are exported into the
environment, for example package contains the name of the package, non_epoch_version contains the
version of the package without the epoch, upstream_version contains the upstream version.
debian_version contains the debian revision. cvstag contains the cvs tag, and cvs_upstream_tag
contains the tag for the upstream version.
-H<hook_script>
This option, if set, should point to a script that should be run just before calling
dpkg-buildpackage. Ideally, things like this are done using the modules file and programs, but is
still provided here for convenience. This script is called with two arguments, the package name,
and version. There a number of variables that are exported into the environment, for example
package contains the name of the package, non_epoch_version contains the version of the package
without the epoch, upstream_version contains the upstream version. debian_version contains the
debian revision. cvstag contains the cvs tag, and cvs_upstream_tag contains the tag for the
upstream version. This argument overrides the settings in the environment variable CVSDEB_HOOK
which in turn over rides the configuration file option conf_hook_script.
-x<prefix>
This option provides the CVS default module prefix (should really fix the CVS modules file). This
argument overrides the settings in the environment variable CVSDEB_PREFIX. Note: The
configuration file variable conf_prefix is not honoured by cvs-buildpackage, since the prefix is
required to calculate the variables that are supposed to be defined when we load the config file
(chicken and egg problem).
The rest of the command line arguments are passed on, uninterpreted, to dpkg-buildpackage, though we do
pay attention to the -r (root command) option (which gives the command to achieve root access, usually
sudo, fakeroot, or super ). The -r option overrides the other means of setting the root command, namely,
the environment variable CVSDEB_ROOTCOMMAND, which in turn overrides the config file option
conf_rootcommand. No attempt is made to check any other option. Please use the -h option to see which of
the dpkg-buildpackage options are supported and passed on.
FILES
Apart from the runtime options, cvs-buildpackage also looks for site-wide defaults in the file
/etc/cvsdeb.conf. After that, it looks for and reads ~/.cvsdeb.conf . The default configuration allows
there to be a site wide override for the root or the cvs-buildpackage working directories on the site,
but the cvsdeb.conf files are actually Bourne shell snippets, and any legal shell directives may be
included in there. Note: Caution is urged with this file, since you can totally change the way that the
script behaves by suitable editing this file.
