NAME
Dpkg::Source::Package - manipulate Debian source packages
DESCRIPTION
This module provides a class that can manipulate Debian source
packages. While it supports both the extraction and the creation of
source packages, the only API that is officially supported is the one
that supports the extraction of the source package.
FUNCTIONS
$string = get_default_diff_ignore_regex()
Returns the default diff ignore regex.
set_default_diff_ignore_regex($string)
Set a regex as the new default diff ignore regex.
@array = get_default_tar_ignore_pattern()
Returns the default tar ignore pattern, as an array.
METHODS
$p = Dpkg::Source::Package->new(%opts, options => {})
Creates a new object corresponding to a source package. When the
key filename is set to a .dsc file, it will be used to initialize
the source package with its description. Otherwise if the format
key is set to a valid value, the object will be initialized for
that format (since dpkg 1.19.3).
The options key is a hash ref which supports the following options:
skip_debianization
If set to 1, do not apply Debian changes on the extracted
source package.
skip_patches
If set to 1, do not apply Debian-specific patches. This
options is specific for source packages using format "2.0"
and "3.0 (quilt)".
require_valid_signature
If set to 1, the check_signature() method will be stricter
and will error out if the signature can't be verified.
require_strong_checksums
If set to 1, the check_checksums() method will be stricter
and will error out if there is no strong checksum.
copy_orig_tarballs
If set to 1, the extraction will copy the upstream tarballs
next the target directory. This is useful if you want to be
able to rebuild the source package after its extraction.
$p->get_filename()
Returns the filename of the DSC file.
$p->get_files()
Returns the list of files referenced by the source package. The
filenames usually do not have any path information.
$p->check_checksums()
Verify the checksums embedded in the DSC file. It requires the
presence of the other files constituting the source package. If any
inconsistency is discovered, it immediately errors out. It will
make sure at least one strong checksum is present.
If the object has been created with the "require_strong_checksums"
option, then any problem will result in a fatal error.
$p->get_upstream_signing_key($dir)
Get the filename for the upstream key.
$p->armor_original_tarball_signature($bin, $asc)
Convert a signature from binary to ASCII armored form. If the
signature file does not exist, it is a no-op. If the signature file
is already ASCII armored then simply copy it, otherwise convert it
from binary to ASCII armored form.
$p->check_original_tarball_signature($dir, @asc)
Verify the original upstream tarball signatures @asc using the
upstream public keys. It requires the origin upstream tarballs,
their signatures and the upstream signing key, as found in an
unpacked source tree $dir. If any inconsistency is discovered, it
immediately errors out.
$bool = $p->is_signed()
Returns 1 if the DSC files contains an embedded OpenPGP signature.
Otherwise returns 0.
$p->check_signature()
Implement the same OpenPGP signature check that dpkg-source does.
In case of problems, it prints a warning or errors out.
If the object has been created with the "require_valid_signature"
option, then any problem will result in a fatal error.
$p->extract($targetdir)
Extracts the source package in the target directory $targetdir.
Beware that if $targetdir already exists, it will be erased (as
long as the no_overwrite_dir option is set).
