PROGRAM:

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.
