NAME
uupdate - upgrade a source code package from an upstream revision
SYNOPSIS
uupdate [options] new_upstream_archive [version]
uupdate [options] --find|-f
uupdate [options] --patch|-p patch_file
DESCRIPTION
uupdate modifies an existing Debian source code archive to reflect an upstream update sup-
plied as a patch or from a wholly new source code archive. The utility needs to be in-
voked from the top directory of the old source code directory, and if a relative name is
given for the new archive or patch file, it will be looked for first relative to the exe-
cution directory and then relative to the parent of the source tree. (For example, if the
changelog file is /usr/local/src/foo/foo-1.1/debian/changelog, then the archive or patch
file will be looked for relative to /usr/local/src/foo.) Note that the patch file or ar-
chive cannot be within the source tree itself. The full details of what the code does are
given below.
Currently supported source code file types are .tar.gz, .tar.bz2, .tar.Z, .tgz, .tar,
.tar.lzma, .tar.xz, .7z and .zip archives. Also supported are already unpacked source
code archives; simply give the path of the source code directory. Supported patch file
types are gzip-compressed, bzip2-compressed, lzma-compressed, xz-compressed and uncom-
pressed patch files. The file types are identified by the file names, so they must use
the standard suffixes.
Usually uupdate will be able to deduce the version number from the source archive name (as
long as it only contains digits and periods). If that fails, you need to specify the ver-
sion number explicitly (without the Debian release number which will always be initially
"1", or "0ubuntu1" on Ubuntu-detected systems). This can be done with an initial --up-
stream-version or -v option, or in the case of an archive, with a version number after the
filename. (The reason for the latter is so that uupdate can be called directly from us-
can.)
Since uupdate uses debuild to clean the current archive before trying to apply a patch
file, it accepts a --rootcmd or -r option allowing the user to specify a gain-root command
to be used. The default is to use fakeroot.
If an archive is being built, the pristine upstream source should be used to create the
.orig.tar.gz file wherever possible. This means that MD5 sums or other similar methods
can be used to easily compare the upstream source to Debian's copy of the upstream ver-
sion. This is the default behaviour, and can be switched off using the --no-pristine op-
tion below.
OPTIONS
This is a summary of what was explained above.
--no-conf, --noconf
Do not read any configuration files. This can only be used as the first option
given on the command-line.
--upstream-version version, -v version
Specify the version number of the upstream package explicitly.
--force-bad-version, -b
Force a version number to be less than the current one (e.g., when backporting).
--rootcmd gain-root-command, -r gain-root-command
Specify the command to be used to become root to build the package and is passed
onto debuild(1) if it is specified.
--pristine, -u
Treat the source as pristine upstream source and symlink to it from <package>_<ver-
sion>.orig.tar.gz whenever possible. This option has no meaning for patches. This
is the default behaviour.
--no-pristine
Do not attempt to make a <package>_<version>.orig.tar.gz symlink.
--symlink, -s
Simply create a symlink when moving a new upstream .tar.gz archive to the new
<package>_<version>.orig.tar.gz location. This is the default behaviour.
--no-symlink
Copy the upstream .tar.gz to the new location instead of making a symlink, if
<package>_<version>.orig.tar.gz is missing. Otherwise, do nothing.
--find, -f
Find all upstream tarballs in ../ which match <pkg>_<ver-
sion>.orig.tar.{gz|bz2|lzma|xz} or <pkg>_<version>.orig-<compo-
nent>.tar.{gz|bz2|lzma|xz} ; --upstream-version required; pristine source required;
not valid for --patch; This option uses dpkg-source as the backend to enable sup-
port for the multiple upstream tarballs and to resolve minor bugs reported previ-
ously. The use of this option is highly recommended.
--verbose
Give verbose output.
--help, -h
Display a help message and exit successfully.
--version
Display version and copyright information and exit successfully.
CONFIGURATION VARIABLES
The two configuration files /etc/devscripts.conf and ~/.devscripts are sourced in that or-
der to set configuration variables. Command line options can be used to override configu-
ration file settings. Environment variable settings are ignored for this purpose. The
currently recognised variables are:
UUPDATE_PRISTINE
If this is set to no, then it is the same as the --no-pristine command line parame-
ter being used.
UUPDATE_SYMLINK_ORIG
If this is set to no, then it is the same as the --no-symlink command line parame-
ter being used.
UUPDATE_ROOTCMD
This is equivalent to the --rootcmd option.
ACTIONS TAKEN ON AN ARCHIVE
Figure out new version number
Unless an explicit version number is provided, the archive name is analyzed for a
sequence of digits separated by dots. If something like that is found, it is taken
to be the new upstream version number. If not, processing is aborted.
Create the .orig.tar.gz archive
If the --pristine or -u option is specified and the upstream archive is a .tar.gz
or .tgz archive, then this will be copied directly to <package>_<ver-
sion>.orig.tar.gz.
Unpacking
The archive is unpacked and placed in a directory with the correct name according
to Debian policy: package-upstream_version.orig. Processing is aborted if this di-
rectory already exists.
Patching
The .diffs.gz from the current version are applied to the unpackaged archive. A
non-zero exit status and warning message will occur if the patches did not apply
cleanly or if no patch file was found. Also, the list of rejected patches will be
shown. The file debian/rules is made executable and all of the .orig files created
by patch are deleted.
Changelog update
A changelog entry with the new version number is generated with the text "New up-
stream release".
When used on Ubuntu systems, dpkg-vendor detection is used to set the Debian revi-
sion to "0ubuntu1". You may change debian/changelog manually afterwards.
ACTIONS TAKEN ON A PATCH FILE
Figure out new version number
Unless an explicit version number is provided, the patch file name is analyzed for
a sequence of digits separated by dots. If something like that is found, it is
taken to be the new upstream version number. If not, processing is aborted.
Clean the current source tree
The command debuild clean is executed within the current Debian source archive to
clean it. If a -r option is given to uupdate, it is passed on to debuild.
Patching
The current source archive (.orig.tar.gz) is unpacked and the patch applied to the
original sources. If this is successful, then the .orig directory is renamed to
reflect the new version number and the current Debian source directory is copied to
a directory with the new version number, otherwise processing is aborted. The
patch is then applied to the new copy of the Debian source directory. The file de-
bian/rules is made executable and all of the .orig files created by patch are
deleted. If there was a problem with the patching, a warning is issued and the
program will eventually exit with non-zero exit status.
Changelog update
A changelog entry with the new version number is generated with the text "New up-
stream release".
When used on Ubuntu systems, dpkg-vendor detection is used to set the Debian revi-
sion to "0ubuntu1". You may change debian/changelog manually afterwards.
