=head1 NAME
URPM - Manipulate RPM files and headers
=head1 SYNOPSIS
use URPM;
# using the local RPM database
my $db = URPM::DB::open();
$db->traverse(sub {
my ($package) = @_; # this is a URPM::Package object
print $package->name, "\n";
# ...
});
# loading and parsing a synthesis file
my $urpm = new URPM;
$urpm->parse_synthesis("synthesis.sample.cz");
$urpm->traverse(sub {
# retrieve all packages from the dependency list
# ...
});
=head1 DESCRIPTION
The URPM module allows you to manipulate RPM files, RPM header files and
hdlist files and manage them in memory. It is notably used by the L<urpmi>
utility. It provides four classes : C<URPM>, C<URPM::DB>, C<URPM::Package>,
and C<URPM::Transaction>.
=head2 The URPM class
=head3 Initialization
=over 4
=item URPM->new()
The constructor creates a new, empty URPM object. It's a blessed hash that
contains three fields:
=over
=item *
B<depslist> is an arrayref containing the list of depending packages (which are
C<URPM::Package> objects).
=item *
B<obsoletes> is an hashref containing as keys the list of property names
obsoleted by the URPM object.
=item *
B<provides> is an hashref containing as keys the list of property names
provided by the URPM object. The associated value is true if the property is
versioned.
=back
If the constructor is called with the arguments C<< nofatal => 1 >>, various
fatal error messages are suppressed (file not found in parse_hdlist() and
parse_synthesis()).
=item URPM::read_config_files()
Force the re-reading of the RPM configuration files.
=back
=head3 Loading packages data
$urpm->{depslist} is loaded when parsing sources (synthesis, hdlists or a plain
rpm file).
=over
=item $urpm->parse_synthesis($file [, callback => sub {...} ])
This method gets the B<depslist> and the B<provides> from a synthesis file
and adds them to the URPM object.
Callback signature is callback(C<URPM>, C<URPM::Package>).
The return value is a two-element array containing the first and the last id
parsed.
=item $urpm->parse_hdlist($file, %options)
This method loads rpm informations from rpm headers contained in an hdlist
file and adds them to the URPM object. Allowed options are
packing => 0 / 1
callback => sub { ... }
keep_all_tags => 0 / 1
Callback signature is callback(C<URPM>, C<URPM::Package>).
The return value is a two-element array containing the first and the last id
parsed.
=item $urpm->parse_rpm($file, %options)
This method gets the B<depslist> and the B<provides> from an RPM file
and adds them to the URPM object. Allowed options are
packing => 0 / 1
keep_all_tags => 0 / 1
callback => sub { ... }
If C<keep_all_tags> isn't specified, URPM will drop all memory-consuming tags
(notably changelogs, filelists, scriptlets).
Callback signature is callback(URPM::Package).
=back
=head3 Searching packages
=over
=item URPM::ranges_overlap($range1, $range2)
This utility function compares two version ranges, in order to calculate
dependencies properly. The ranges have roughly the form
[<|<=|==|=>|>] [epoch:]version[-release]
where epoch, version and release are RPM-style version numbers.
=item $urpm->packages_providing($name)
Returns a list of C<URPM::Package> providing <$name>
=item $urpm->packages_by_name($name)
Returns a list of C<URPM::Package> corresponding to the wanted <$name>
=item $urpm->search($name, %options)
Search an RPM by name or by part of name in the list of RPMs represented by
this $urpm. The behaviour of the search is influenced by several options:
=over
=item strict_name only match short name (N) => 0 / 1
=item strict_fullname only match fullname (NVRA) (fast) => 0 / 1
=item src => look only for srpms => 0 / 1
=back
=back
=head3 Debuging
These are used when faking a URPM::DB: $urpm can be used as-a $db
=over
=item $urpm->traverse($callback)
Executes the callback for each package in the depslist, passing a
C<URPM::Package> object as argument the callback.
=item $urpm->traverse_tag($tag, $names, $callback)
$tag may be one of C<name>, C<whatprovides>, C<whatrequires>, C<whatconflicts>,
C<group>, C<triggeredby>, or C<path>.
$names is a reference to an array, holding the acceptable values of the said
tag for the searched variables.
Then, $callback is called for each matching package in the depslist.
Callback signature is callback(URPM::Package).
=item $urpm->traverse_tag_find($tag,$name,$callback)
Quite similar to C<traverse_tag>, but stops when $callback returns true.
(also note that only one $name is handled)
Callback signature is callback(URPM::Package).
=back
=head3 Checking packages
=over
=item URPM::verify_rpm($file, %options)
Verifies an RPM file.
Returns 0 on failure, 1 on success.
Recognized options are:
nodigests => 0 / 1
nosignatures => 0 / 1
=item URPM::verify_signature($file)
Verifies the signature of an RPM file. Returns a string that will contain "OK"
or "NOT OK" as well as a description of the found key (if successful) or of the
error (if signature verification failed.)
=item $urpm->import_pubkey(%options)
Imports a key in the RPM database.
db => $urpm_db
root => '...'
block => '...'
filename => '...'
=back
=head2 The URPM::DB class
=over 4
=item open($prefix, $write_perm)
Returns a new C<URPM::DB> object pointing on the local RPM database (or
C<undef> on failure).
$prefix defaults to C<""> and indicates the RPM DB root directory prefix if
any. (See the B<--root> option to rpm(1)).
$write_perm is a boolean that defaults to false, and that indicates whether
the RPM DB should be open in read/write mode.
=item rebuild($prefix)
Rebuilds the RPM database (like C<rpm --rebuilddb>). $prefix defaults to C<"">.
=item verify($prefix)
Verify the RPM database (like C<rpmdb --verify>). $prefix defaults to C<"">.
=item $db->traverse($callback)
Executes the specified callback (a code reference) for each package
in the DB, passing a C<URPM::Package> object as argument the callback.
Returns the number of packages seen (all).
=item $db->traverse_tag($tag,$names,$callback)
$tag may be one of C<name>, C<whatprovides>, C<whatrequires>, C<whatconflicts>,
C<group>, C<triggeredby>, or C<path>.
$names is a reference to an array, holding the acceptable values of the said
tag for the searched variables.
Then, $callback is called for each matching package in the DB.
Callback signature is callback(URPM::Package).
Returns the number of packages seen (all those that matched provided names).
=item $db->traverse_tag_find($tag,$name,$callback)
Quite similar to C<traverse_tag>, but stops when $callback returns true.
(also note that only one $name is handled)
Callback signature is callback(URPM::Package).
Returns whether callback returned true once.
=item $db->create_transaction()
Creates and returns a new transaction (an C<URPM::Transaction> object) on the
specified DB.
=back
=head2 The URPM::Package class
=head3 Getting a URPM::Package object
URPM::Package objects are usually retrieved from $urpm->{depslist} after
having loaded either the RPM DB and/or synthesis files.
It's also possible to get such an object with:
=over
=item URPM::spec2srcheader($specfile)
Returns a URPM::Package object containing the header of the source rpm produced
by the evaluation of the specfile whose path is given as argument. All
dependencies stored in this header are exactly the one needed to build the
specfile.
=item URPM::stream2header($fp)
Returns a URPM::Package object containing the header read from $fp.
=back
=head3 Methods
Most methods of C<URPM::Package> are accessors for the various properties
of an RPM package.
=over 4
=item $package->arch()
Gives the package architecture
=item $package->build_header($fileno)
Writes the rpm header to the specified file ($fileno being an integer).
=item $package->build_info($fileno, [$provides_files])
Writes a line of information in a synthesis file.
=item $package->buildarchs()
=item $package->buildhost()
=item $package->buildtime()
=item $package->changelog_name()
=item $package->changelog_text()
=item $package->changelog_time()

Full conflicts tags
=item $package->conflicts_nosense()
Just the conflicted package name.
This is only used when faking a URPM::DB: $urpm can be used as-a $db
=item $package->description()
=item $package->dirnames()
=item $package->distribution()
=item $package->epoch()
=item $package->EVR()

=item $package->filelinktos()
=item $package->files()
List of files in this rpm.
=item $package->files_flags()
=item $package->files_gid()
=item $package->files_group()
=item $package->files_md5sum()
=item $package->files_mode()
=item $package->files_mtime()
=item $package->files_owner()
=item $package->files_size()
=item $package->files_uid()
=item $package->flag($name)

=item $package->flag_required()
=item $package->flag_selected()
=item $package->flag_skip()
=item $package->flag_upgrade()
=item $package->free_header()
=item $package->fullname()
Returns a 4 element list: name, version, release and architecture in an array
context. Returns a string NAME-VERSION-RELEASE.ARCH in scalar context.
=item $package->get_tag($tagid)
Returns an array containing values of $tagid. $tagid is the numerical value of
rpm tags. See rpmlib.h.
=item $package->queryformat($format)
Querying the package like rpm --queryformat do.
The function calls directly the rpmlib, then use header informations, so it
silently failed if you use synthesis instead of hdlist/rpm/header files or rpmdb.
=item $package->get_tag_modifiers($tagid)
Return an array of human readable view of tag values. $tagid is the numerical value of rpm tags.
=item $package->group()
=item $package->id()
=item $package->installtid()
=item $package->is_arch_compat()
Returns whether this package is compatible with the current machine's
architecture. 0 means not compatible. The lower the result is, the preferred
the package is.
=item $package->license()
=item $package->name()

=item $package->obsoletes()
Full obsoletes tags
=item $package->obsoletes_nosense()
Just the obsoleted package name.

If a header is associated with the package, fill the package fields from
the header's tags (NEVRA,
requires/recommends/obsoletes/conflicts/provides/summary)
then free the header
It's useful when traversing the rpm DB, if one wants to keep around a
package from the DB
else the info would not be available outside the traverse_*() function.
It's also useful when creating a URPM_Package from a package file in
order to shrink memory footprint.
=item $package->packager()

=back
=head2 The URPM::Transaction class
=over 4
=item $trans->set_script_fd($fileno)
Sets the transaction output filehandle.
=item $trans->add($pkg, %options)
Adds a package to be installed to the transaction represented by $trans.
$pkg is an C<URPM::Package> object.
Options are:
update => 0 / 1 : indicates whether this is an upgrade
excludepath => [ ... ]
=item $trans->remove($name)
Adds a package to be erased to the transaction represented by $trans.
$name is the name of the package.
=item $trans->check(%options)
Checks that all dependencies can be resolved in this transaction.
Options are:
translate_message => 0 / 1 (currently ignored.)
In list context, returns an array of problems (an empty array indicates
success).
=item $trans->order()
Determines package order in a transaction set according to dependencies. In
list context, returns an array of problems (an empty array indicates success).
=item $trans->run($data, %options)
Runs the transaction.
$data is an arbitrary user-provided piece of data to be passed to callbacks.
It's usually the $urpm object.
Recognized options are:
callback_close => sub { ... }
callback_elem => sub { ... }
callback_error => sub { ... }
callback_inst => sub { ... }
callback_open => sub { ... }
callback_trans => sub { ... }
callback_uninst => sub { ... }
delta => used for progress callbacks (trans, uninst, inst)
excludedocs => 0 / 1
force => 0 / 1
ignorearch => 0 / 1
nosize => 0 / 1
noscripts => 0 / 1
oldpackage => 0 / 1
test => 0 / 1
translate_message => 1
They roughly correspond to command-line options to rpm(1).
'callback_open' signature is (C<$data>, C<$cb_type>, C<$pkg_id>, C<pkg_name>). It _must_ return a file handler for the asked package.
'callback_close' signature is (C<$data>, C<$cb_type>, C<$pkg_id>, C<pkg_name>). It is called just before URPM close the fd for the installed package.
C<$cb_type> is one of 'open' or 'close'.
Other Callbacks signature is callback(C<$data>, C<$cb_type>, C<$pkg_id>, C<$subtype>, C<$amout>, C<$total>, C<pkg_name>)
C<$cb_type> is one of 'elem', 'error', 'inst', 'trans' or 'uninst'. C<$subtype> can be 'start', 'progress' or 'stop'.
For 'error', it can be 'cpio', 'script' or 'unpack'.
The purpose of those callbacks is to report progress (the two last parameters (C<$amount> & C<$total>) enable to compute progress percentage).
=item $trans->traverse($callback)
Executes the specified callback (a code reference) for each package in the
transaction, passing a C<URPM::Package> object as argument the callback.
=back
=head3 Transaction Element management
=over 4
=item $trans->NElements($fileno)
Returns the number of elements in the transaction.
=item $trans->Element_version($index)
Returns the version of the $index-th element in the transaction.
=item $trans->Element_release($index)
Returns the release of the $index-th element in the transaction.
=item $trans->Element_fullname($index)
Returns the fullname of the $index-th element in the transaction.
=back
=head2 Macro handling functions
=over
=item loadmacrosfile($filename)
Load the specified macro file. Sets $! if the file can't be read.
=item expand($name)
Expands the specified macro.
=item add_macro($macro_definition)
=item add_macro_noexpand($macro_definition)

=back
=head2 Misc other functions
=over
