12 Debbugs::Bugs -- Bug selection routines for debbugs
16 use Debbugs::Bugs qw(get_bugs);
21 This module is a replacement for all of the various methods of
22 selecting different types of bugs.
24 It implements a single function, get_bugs, which defines the master
25 interface for selecting bugs.
27 It attempts to use subsidiary functions to actually do the selection,
28 in the order specified in the configuration files. [Unless you're
29 insane, they should be in order from fastest (and often most
30 incomplete) to slowest (and most complete).]
40 use vars qw($VERSION $DEBUG %EXPORT_TAGS @EXPORT_OK @EXPORT);
41 use base qw(Exporter);
45 $DEBUG = 0 unless defined $DEBUG;
49 @EXPORT_OK = (qw(get_bugs count_bugs newest_bug bug_filter));
50 $EXPORT_TAGS{all} = [@EXPORT_OK];
53 use Debbugs::Config qw(:config);
54 use Params::Validate qw(validate_with :types);

70 The following parameters can either be a single scalar or a reference
71 to an array. The parameters are ANDed together, and the elements of
72 arrayrefs are a parameter are ORed. Future versions of this may allow
73 for limited regular expressions, and/or more complex expressions.
77 =item package -- name of the binary package
79 =item src -- name of the source package
81 =item maint -- address of the maintainer
83 =item submitter -- address of the submitter
85 =item severity -- severity of the bug
87 =item status -- status of the bug
91 =item owner -- owner of the bug
93 =item correspondent -- address of someone who sent mail to the log
95 =item affects -- bugs which affect this package
97 =item dist -- distribution (I don't know about this one yet)
99 =item bugs -- list of bugs to search within
101 =item function -- see description below
105 =head3 Special options
107 The following options are special options used to modulate how the
108 searches are performed.
112 =item archive -- whether to search archived bugs or normal bugs;
113 defaults to false. As a special case, if archive is 'both', but
114 archived and unarchived bugs are returned.
116 =item usertags -- set of usertags and the bugs they are applied to
121 =head3 Subsidiary routines
123 All subsidiary routines get passed exactly the same set of options as
124 get_bugs. If for some reason they are unable to handle the options
125 passed (for example, they don't have the right type of index for the
126 type of selection) they should die as early as possible. [Using
127 Params::Validate and/or die when files don't exist makes this fairly
130 This function will then immediately move on to the next subroutine,
131 giving it the same arguments.
135 This option allows you to provide an arbitrary function which will be
136 given the information in the index.db file. This will be super, super
137 slow, so only do this if there's no other way to write the search.
139 You'll be given a list (which you can turn into a hash) like the

145 submitter => 'boo@baz.com',
146 severity => 'serious',
