getpkgsrc¶

Returns a reference to a hash of binary package names to their corresponding source package names.

getpkgcomponent¶

Returns a reference to a hash of binary package names to the component of the archive containing those binary packages (e.g. "main", "contrib", "non-free").

getsrcpkgs¶

Returns a list of the binary packages produced by a given source package.

binary_to_source¶

     binary_to_source(package => 'foo',
                      version => '1.2.3',
                      arch    => 'i386');

Turn a binary package (at optional version in optional architecture) into a single (or set) of source packages (optionally) with associated versions.

By default, in LIST context, returns a LIST of array refs of source package, source version pairs corresponding to the binary package(s), arch(s), and verion(s) passed.

In SCALAR context, only the corresponding source packages are returned, concatenated with ', ' if necessary.

If no source can be found, returns undef in scalar context, or the empty list in list context.

binary -- binary package name(s) as a SCALAR or ARRAYREF

version -- binary package version(s) as a SCALAR or ARRAYREF; optional, defaults to all versions.

arch -- binary package architecture(s) as a SCALAR or ARRAYREF; optional, defaults to all architectures.

source_only -- return only the source name (forced on if in SCALAR context), defaults to false.

scalar_only -- return a scalar only (forced true if in SCALAR context, also causes source_only to be true), defaults to false.

cache -- optional HASHREF to be used to cache results of binary_to_source.

sourcetobinary¶

Returns a list of references to triplets of binary package names, versions, and architectures corresponding to a given source package name and version. If the given source package name and version cannot be found in the database but the source package name is in the unversioned package-to-source map file, then a reference to a binary package name and version pair will be returned, without the architecture.

getversions¶

Returns versions of the package in a distribution at a specific architecture

get_versions¶

     get_versions(package=>'foopkg',
                  dist => 'unstable',
                  arch => 'i386',
                 );

Returns a list of the versions of package in the distributions and architectures listed. This routine only returns unique values.

package -- package to return list of versions

dist -- distribution (unstable, stable, testing); can be an arrayref

arch -- architecture (i386, source, ...); can be an arrayref

time -- returns a version=>time hash at which the newest package matching this version was uploaded

source -- returns source/version instead of just versions

no_source_arch -- discards the source architecture when arch is not passed. [Used for finding the versions of binary packages only.] Defaults to 0, which does not discard the source architecture. (This may change in the future, so if you care, please code accordingly.)

return_archs -- returns a version=>[archs] hash indicating which architectures are at which versions.

largest_source_version_only -- if there is more than one source version in a particular distribution, discards all versions but the largest in that distribution. Defaults to 1, as this used to be the way that the Debian archive worked.

When called in scalar context, this function will return hashrefs or arrayrefs as appropriate, in list context, it will return paired lists or unpaired lists as appropriate.

makesourceversions¶

     @{$cgi_var{found}} = makesourceversions($cgi_var{package},undef,@{$cgi_var{found}});

Canonicalize versions into source versions, which have an explicitly named source package. This is used to cope with source packages whose names have changed during their history, and with cases where source version numbers differ from binary version numbers.

make_source_versions¶

     make_source_versions(package => 'foo',
                          arch    => 'source',
                          versions => '0.1.1',
                          guess_source => 1,
                          debug    => \$debug,
                          warnings => \$warnings,
                         );

An extended version of makesourceversions (which calls this function internally) that allows for multiple packages, architectures, and outputs warnings and debugging information to provided SCALARREFs or HANDLEs.

The guess_source option determines whether the source package is guessed at if there is no obviously correct package. Things that use this function for non-transient output should set this to false, things that use it for transient output can set this to true. Currently it defaults to true, but that is not a sane option.
