debdiff-apply - apply a debdiff to a Debian source package
debdiff-apply [options] [orig_dsc_or_dir] [patch_file]
debdiff-apply [options] < [patch_file]
debdiff-apply takes a patchfile that describes the
differences between two Debian source packages old and new,
and applies it to a target Debian source package orig.
orig could either be the same as old or it could be
different. patchfile is expected to be a unified diff between two
Debian source trees, as what debdiff(1) normally generates.
Any changes to debian/changelog are dealt with specially,
to avoid the conflicts that changelog diffs typically produce when applied
naively. The exact behaviour may be tweaked in the future, so one should not
rely on it.
If patchfile does not apply to orig, even after the
special-casing of debian/changelog, no changes are made and
debdiff-apply(1) will exit with a non-zero error code.
- orig_dsc_or_dir
- Target to apply the patch to. This can either be an unpacked source tree,
or a .dsc file. In the former case, the directory is modified in-place; in
the latter case, a second .dsc is created. Default: .
- patch_file
- Patch file to apply, in the format output by debdiff(1). Default:
/dev/stdin
- -h, --help
- show this help message and exit
- -v, --verbose
- Output more information
- -c CHANGELOG,
--changelog CHANGELOG
- Path to debian/changelog; default: debian/changelog
- -D DISTRIBUTION,
--distribution DISTRIBUTION
- Distribution to use, if the patch doesn't already contain a changelog;
default: experimental
- --repl
- Run the python REPL after processing.
- --source-version
- Don't apply the patch; instead print out the version of the package that
it is supposed to be applied to, or nothing if the patch does not specify
a source version.
- --target-version
- Don't apply the patch; instead print out the new version of the package
debdiff-apply(1) would generate, when the patch is applied to the
the given target package, as specified by the other arguments.
- --no-clean
- Don't clean temporary directories after a failure, so you can examine what
failed.
- --quilt-refresh
- If the building of the new source package fails, try to refresh patches
using quilt(1) then try building it again.
- -d DIRECTORY,
--directory DIRECTORY
- Extract the .dsc into this directory, which won't be cleaned up after
debdiff-apply(1) exits. If not given, then it will be extracted to
a temporary directory.
