Dpkg::Source::Package(3perl)

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.

    Options:

    filename
        When set to a .dsc file, it will be used to initialize the source package with its description.

    format
        If set to a valid value, and no filename has been specified, the object will be initialized for that format (since dpkg 1.19.3).

    options
        A hash ref which supports the following source package format 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_basedirname()
    Returns the default base directory name for the package.

$p->get_upstream_signing_key($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).
