NAME

       git-debcherry - export commits touching upstream source as patches

SYNOPSIS

       git-debcherry [options] upstream [integration]

DESCRIPTION

       This  program  will  analyze  git  history  and  try  to  create  a  set of patches meeting the following
       conditions:

           1. Is guaranteed to apply to upstream

           2. Produces the same work tree as integration, outside ./debian

           3. Does not touch ./debian

           4. As much as possible, matches the git history from upstream to integration

BRANCH PARAMETERS

       upstream

              This ref should be suitable for export as a .orig.tar.gz.  In particular note that  quilt  has  no
              way  of  deleting  files  that  does  not include the material to be deleted in the patch, so your
              upstream branch should include any necessary file deletions.

       integration

              This branch contains all debian packaging, plus any changes introduced to upstream source  by  the
              debian  packager.  This argument is optional.  If integration is not passed git-debcherry will use
              HEAD.

OPTIONS

       The following options are available:

       -o, --output-directory directory

              Place output (patches and series file) in directory.  If  unspecified,  output  patches  (in  mbox
              format) to stdout.

       -s, --stat

              Only output diffstat of patches

       -d, --debug
              Output some debugging information. Probably only useful to developers or those reporting bugs.

EXAMPLE

       To export the patches between tag v3.0+dfsg1 and the current branch into ./debian/patches:

        $ git-debcherry -o debian/patches v3.0+dfsg1

NOTES

   PERFORMANCE
       git-debcherry  currently  uses  git-filter-branch(1) to rewrite all commits on the integration branch not
       present upstream. Depending on the number of such commits, this can be noticeably slow.

   DELETED FILES
       git-debcherry currently follows dpkg-source(1) in ignoring file deletions. This  has  the  positive  side
       effect  of  not  bloating  the  patches,  but  if  you really need the files deleted for the build and/or
       licensing reasons, you should delete them in upstream.
