Lintian::Collect::Binary(3) Debian Package Checker Lintian::Collect::Binary(3)

NAME

Lintian::Collect::Binary - Lintian interface to binary package data collection

SYNOPSIS

    my ($name, $type, $dir) = ('foobar', 'binary', '/path/to/lab-entry');
    my $collect = Lintian::Collect::Binary->new($name);

DESCRIPTION

Lintian::Collect::Binary provides an interface to package data for binary packages. It implements data collection methods specific to binary packages.

This module is in its infancy. Most of Lintian still reads all data from files in the laboratory whenever that data is needed and generates that data via collect scripts. The goal is to eventually access all data about binary packages via this module so that the module can cache data where appropriate and possibly retire collect scripts in favor of caching that data in memory.

Native heuristics are only available in source packages.

INSTANCE METHODS

In addition to the instance methods listed below, all instance methods documented in the Lintian::Collect and the Lintian::Info::Package modules are also available.
index (FILE)
Returns a path object to FILE in the package. FILE must be relative to the root of the unpacked package and must be without leading slash (or "./"). If FILE is not in the package, it returns "undef". If FILE is supposed to be a directory, it must be given with a trailing slash. Example:

  my $file = $info->index ("usr/bin/lintian");
  my $dir = $info->index ("usr/bin/");
    

To get a list of entries in the package, see "sorted_index". To actually access the underlying file (e.g. the contents), use "unpacked ([FILE])".

Note that the "root directory" (denoted by the empty string) will always be present, even if the underlying tarball omits it.

Needs-Info requirements for using index: unpacked

strings (FILE)
Returns an open handle, which will read the data from coll/strings for FILE. If coll/strings did not collect any strings about FILE, this returns an open read handle with no content.

Caller is responsible for closing the handle either way.

Needs-Info requirements for using strings: strings

relation (FIELD)
Returns a Lintian::Relation object for the specified FIELD, which should be one of the possible relationship fields of a Debian package or one of the following special values:
all
The concatenation of Pre-Depends, Depends, Recommends, and Suggests.
strong
The concatenation of Pre-Depends and Depends.
weak
The concatenation of Recommends and Suggests.

If FIELD isn't present in the package, the returned Lintian::Relation object will be empty (always satisfied and implies nothing).

Needs-Info requirements for using relation: Same as field

is_pkg_class ([TYPE])
Returns a truth value if the package is the given TYPE of special package. TYPE can be one of "transitional", "debug" or "any-meta". If omitted it defaults to "any-meta". The semantics for these values are:
transitional
The package is (probably) a transitional package (e.g. it is probably empty, just depend on stuff will eventually disappear.)

Guessed from package description.

any-meta
This package is (probably) some kind of meta or task package. A meta package is usually empty and just depend on stuff. It will also return a truth value for "tasks" (i.e. tasksel "tasks").

A transitional package will also match this.

Guessed from package description, section or package name.

debug
The package is (probably) a package containing debug symbols.

Guessed from the package name.

auto-generated
The package is (probably) a package generated automatically (e.g. a dbgsym package)

Guessed from the "Auto-Built-Package" field.

Needs-Info requirements for using is_pkg_class: Same as field

is_non_free
Returns a truth value if the package appears to be non-free (based on the section field; "non-free/*" and "restricted/*")

Needs-Info requirements for using is_non_free: "field ([FIELD[, DEFAULT]])"
