uupdate


SYNOPSIS
       uupdate [options] new_upstream_archive [version]
       uupdate [options] --patch|-p patch_file

DESCRIPTION
       uupdate  modifies  an existing Debian source code archive to reflect an
       upstream update supplied as a patch or from a wholly  new  source  code
       archive.  The utility needs to be invoked 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 archive 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
       uncompressed 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 version number explicitly (with-
       out the Debian release number which will always be  initially  "1",  or
       "0ubuntu1"  on Ubuntu-detected systems).  This can be done with an ini-
       tial --upstream-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 uscan.)

       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 version.  This  is
       the  default behaviour, and can be switched off using the --no-pristine
       option below.

OPTIONS
       This is a summary of what was explained above.

       --upstream-version version, -v version
              Specify the version number of the upstream package explicitly.

       --rootcmd gain-root-command, -r gain-root-command

       --symlink, -s
              Simply  create  a symlink when moving a new upstream .tar.gz ar-
              chive 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.

       --no-conf, --noconf
              Do not read any configuration files.  This can only be  used  as
              the first option given on the command-line.

       --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 order to set  configuration  variables.   Command  line
       options  can be used to override configuration file settings.  Environ-
       ment 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 parameter being used.

       UUPDATE_SYMLINK_ORIG
              If this is set to no, then it is the same  as  the  --no-symlink
              command line parameter 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 ar-
              chive  is  a  .tar.gz  or .tgz archive, then this will be copied
              directly to <package>_<version>.orig.tar.gz.

       Unpacking
              The archive is unpacked and placed in a directory with the  cor-
              rect  name  according  to  Debian  policy: package-upstream_ver-
              sion.orig.  Processing is  aborted  if  this  directory  already
              the text "New upstream release".

              When  used  on  Ubuntu systems, dpkg-vendor detection is used to
              set  the  Debian  revision  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  debian/rules  is  made  exe-
              cutable 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 upstream release".

              When used on Ubuntu systems, dpkg-vendor detection  is  used  to
              set   the   Debian  revision  to  "0ubuntu1".   You  may  change
              debian/changelog manually afterwards.
