-package CPAN::Queue;
-
-# One use of the queue is to determine if we should or shouldn't
-# announce the availability of a new CPAN module
-
-# Now we try to use it for dependency tracking. For that to happen
-# we need to draw a dependency tree and do the leaves first. This can
-# easily be reached by running CPAN.pm recursively, but we don't want
-# to waste memory and run into deep recursion. So what we can do is
-# this:
-
-# CPAN::Queue is the package where the queue is maintained. Dependencies
-# often have high priority and must be brought to the head of the queue,
-# possibly by jumping the queue if they are already there. My first code
-# attempt tried to be extremely correct. Whenever a module needed
-# immediate treatment, I either unshifted it to the front of the queue,
-# or, if it was already in the queue, I spliced and let it bypass the
-# others. This became a too correct model that made it impossible to put
-# an item more than once into the queue. Why would you need that? Well,
-# you need temporary duplicates as the manager of the queue is a loop
-# that
-#
-# (1) looks at the first item in the queue without shifting it off
-#
-# (2) cares for the item
-#
-# (3) removes the item from the queue, *even if its agenda failed and
-# even if the item isn't the first in the queue anymore* (that way
-# protecting against never ending queues)
-#
-# So if an item has prerequisites, the installation fails now, but we
-# want to retry later. That's easy if we have it twice in the queue.
-#
-# I also expect insane dependency situations where an item gets more
-# than two lives in the queue. Simplest example is triggered by 'install
-# Foo Foo Foo'. People make this kind of mistakes and I don't want to
-# get in the way. I wanted the queue manager to be a dumb servant, not
-# one that knows everything.
-#
-# Who would I tell in this model that the user wants to be asked before
-# processing? I can't attach that information to the module object,
-# because not modules are installed but distributions. So I'd have to
-# tell the distribution object that it should ask the user before
-# processing. Where would the question be triggered then? Most probably
-# in CPAN::Distribution::rematein.
-# Hope that makes sense, my head is a bit off:-) -- AK

-=head1 NAME
-
-CPAN - query, download and build perl modules from CPAN sites
-
-=head1 SYNOPSIS
-
-Interactive mode:
-
- perl -MCPAN -e shell;
-
-Batch mode:
-
- use CPAN;
-
- autobundle, clean, install, make, recompile, test
-
-=head1 DESCRIPTION
-
-The CPAN module is designed to automate the make and install of perl
-modules and extensions. It includes some searching capabilities and
-knows how to use Net::FTP or LWP (or lynx or an external ftp client)
-to fetch the raw data from the net.
-
-Modules are fetched from one or more of the mirrored CPAN
-(Comprehensive Perl Archive Network) sites and unpacked in a dedicated
-directory.
-
-The CPAN module also supports the concept of named and versioned
-I<bundles> of modules. Bundles simplify the handling of sets of
-related modules. See Bundles below.
-
-The package contains a session manager and a cache manager. There is
-no status retained between sessions. The session manager keeps track
-of what has been fetched, built and installed in the current
-session. The cache manager keeps track of the disk space occupied by
-the make processes and deletes excess space according to a simple FIFO
-mechanism.
-
-For extended searching capabilities there's a plugin for CPAN available,
-L<C<CPAN::WAIT>|CPAN::WAIT>. C<CPAN::WAIT> is a full-text search engine
-that indexes all documents available in CPAN authors directories. If
-C<CPAN::WAIT> is installed on your system, the interactive shell of
-CPAN.pm will enable the C<wq>, C<wr>, C<wd>, C<wl>, and C<wh> commands
-which send queries to the WAIT server that has been configured for your
-installation.
-
-All other methods provided are accessible in a programmer style and in an
-interactive shell style.
-
-=head2 Interactive Mode
-
-The interactive mode is entered by running
-
- perl -MCPAN -e shell
-
-which puts you into a readline interface. You will have the most fun if
-you install Term::ReadKey and Term::ReadLine to enjoy both history and
-command completion.
-
-Once you are on the command line, type 'h' and the rest should be
-self-explanatory.
-
-The function call C<shell> takes two optional arguments, one is the
-prompt, the second is the default initial command line (the latter
-only works if a real ReadLine interface module is installed).
-
-The most common uses of the interactive modes are
-
-=over 2
-
-=item Searching for authors, bundles, distribution files and modules
-
-There are corresponding one-letter commands C<a>, C<b>, C<d>, and C<m>
-for each of the four categories and another, C<i> for any of the
-mentioned four. Each of the four entities is implemented as a class
-with slightly differing methods for displaying an object.
-
-Arguments you pass to these commands are either strings exactly matching
-the identification string of an object or regular expressions that are
-then matched case-insensitively against various attributes of the
-objects. The parser recognizes a regular expression only if you
-enclose it between two slashes.
-
-The principle is that the number of found objects influences how an
-item is displayed. If the search finds one item, the result is
-displayed with the rather verbose method C<as_string>, but if we find
-more than one, we display each object with the terse method
-<as_glimpse>.
-
-=item make, test, install, clean modules or distributions
-
-These commands take any number of arguments and investigate what is
-necessary to perform the action. If the argument is a distribution
-file name (recognized by embedded slashes), it is processed. If it is
-a module, CPAN determines the distribution file in which this module
-is included and processes that, following any dependencies named in
-the module's Makefile.PL (this behavior is controlled by
-I<prerequisites_policy>.)
-
-Any C<make> or C<test> are run unconditionally. An
-
- install <distribution_file>
-
-also is run unconditionally. But for
-
- install <module>
-
-CPAN checks if an install is actually needed for it and prints
-I<module up to date> in the case that the distribution file containing
-the module doesn't need to be updated.
-
-CPAN also keeps track of what it has done within the current session
-and doesn't try to build a package a second time regardless if it
-succeeded or not. The C<force> command takes as a first argument the
-method to invoke (currently: C<make>, C<test>, or C<install>) and executes the
-command from scratch.
-
-Example:
-
- cpan> install OpenGL
- OpenGL is up to date.
- cpan> force install OpenGL
- Running make
- OpenGL-0.4/
- OpenGL-0.4/COPYRIGHT
- [...]
-
-A C<clean> command results in a
-
- make clean
-
-being executed within the distribution file's working directory.
-
-=item get, readme, look module or distribution
-
-C<get> downloads a distribution file without further action. C<readme>
-displays the README file of the associated distribution. C<Look> gets
-and untars (if not yet done) the distribution file, changes to the
-appropriate directory and opens a subshell process in that directory.
-
-=item ls author
-
-C<ls> lists all distribution files in and below an author's CPAN
-directory. Only those files that contain modules are listed and if
-there is more than one for any given module, only the most recent one
-is listed.
-
-=item Signals
-
-CPAN.pm installs signal handlers for SIGINT and SIGTERM. While you are
-in the cpan-shell it is intended that you can press C<^C> anytime and
-return to the cpan-shell prompt. A SIGTERM will cause the cpan-shell
-to clean up and leave the shell loop. You can emulate the effect of a
-SIGTERM by sending two consecutive SIGINTs, which usually means by
-pressing C<^C> twice.
-
-CPAN.pm ignores a SIGPIPE. If the user sets inactivity_timeout, a
-SIGALRM is used during the run of the C<perl Makefile.PL> subprocess.
-
-=back
-
-=head2 CPAN::Shell
-
-The commands that are available in the shell interface are methods in
-the package CPAN::Shell. If you enter the shell command, all your
-input is split by the Text::ParseWords::shellwords() routine which
-acts like most shells do. The first word is being interpreted as the
-method to be called and the rest of the words are treated as arguments
-to this method. Continuation lines are supported if a line ends with a
-literal backslash.
-
-=head2 autobundle
-
-C<autobundle> writes a bundle file into the
-C<$CPAN::Config-E<gt>{cpan_home}/Bundle> directory. The file contains
-a list of all modules that are both available from CPAN and currently
-installed within @INC. The name of the bundle file is based on the
-current date and a counter.
-
-=head2 recompile
-
-recompile() is a very special command in that it takes no argument and
-runs the make/test/install cycle with brute force over all installed
-dynamically loadable extensions (aka XS modules) with 'force' in
-effect. The primary purpose of this command is to finish a network
-installation. Imagine, you have a common source tree for two different
-architectures. You decide to do a completely independent fresh
-installation. You start on one architecture with the help of a Bundle
-file produced earlier. CPAN installs the whole Bundle for you, but
-when you try to repeat the job on the second architecture, CPAN
-responds with a C<"Foo up to date"> message for all modules. So you
-invoke CPAN's recompile on the second architecture and you're done.
-
-Another popular use for C<recompile> is to act as a rescue in case your
-perl breaks binary compatibility. If one of the modules that CPAN uses
-is in turn depending on binary compatibility (so you cannot run CPAN
-commands), then you should try the CPAN::Nox module for recovery.
-
-=head2 The four C<CPAN::*> Classes: Author, Bundle, Module, Distribution
-
-Although it may be considered internal, the class hierarchy does matter
-for both users and programmer. CPAN.pm deals with above mentioned four
-classes, and all those classes share a set of methods. A classical
-single polymorphism is in effect. A metaclass object registers all
-objects of all kinds and indexes them with a string. The strings
-referencing objects have a separated namespace (well, not completely
-separated):
-
- Namespace Class
-
- words containing a "/" (slash) Distribution
- words starting with Bundle:: Bundle
- everything else Module or Author
-
-Modules know their associated Distribution objects. They always refer
-to the most recent official release. Developers may mark their releases
-as unstable development versions (by inserting an underbar into the
-visible version number), so the really hottest and newest distribution
-file is not always the default. If a module Foo circulates on CPAN in
-both version 1.23 and 1.23_90, CPAN.pm offers a convenient way to
-install version 1.23 by saying
-
- install Foo
-
-This would install the complete distribution file (say
-BAR/Foo-1.23.tar.gz) with all accompanying material. But if you would
-like to install version 1.23_90, you need to know where the
-distribution file resides on CPAN relative to the authors/id/
-directory. If the author is BAR, this might be BAR/Foo-1.23_90.tar.gz;
-so you would have to say
-
- install BAR/Foo-1.23_90.tar.gz
-
-The first example will be driven by an object of the class
-CPAN::Module, the second by an object of class CPAN::Distribution.
-
-=head2 Programmer's interface
-
-If you do not enter the shell, the available shell commands are both
-available as methods (C<CPAN::Shell-E<gt>install(...)>) and as
-functions in the calling package (C<install(...)>).
-
-There's currently only one class that has a stable interface -
-CPAN::Shell. All commands that are available in the CPAN shell are
-methods of the class CPAN::Shell. Each of the commands that produce
-listings of modules (C<r>, C<autobundle>, C<u>) also return a list of
-the IDs of all modules within the list.
-
-=over 2
-
-=item expand($type,@things)
-
-The IDs of all objects available within a program are strings that can
-be expanded to the corresponding real objects with the
-C<CPAN::Shell-E<gt>expand("Module",@things)> method. Expand returns a
-list of CPAN::Module objects according to the C<@things> arguments
-given. In scalar context it only returns the first element of the
-list.
-
-=item expandany(@things)
-
-Like expand, but returns objects of the appropriate type, i.e.
-CPAN::Bundle objects for bundles, CPAN::Module objects for modules and
-CPAN::Distribution objects fro distributions.
-
-=item Programming Examples
-
-This enables the programmer to do operations that combine
-functionalities that are available in the shell.
-
- # install everything that is outdated on my disk:
- perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'
-
- # install my favorite programs if necessary:
- for $mod (qw(Net::FTP MD5 Data::Dumper)){
- my $obj = CPAN::Shell->expand('Module',$mod);
- $obj->install;
- }
-
- # list all modules on my disk that have no VERSION number
- for $mod (CPAN::Shell->expand("Module","/./")){
- next unless $mod->inst_file;
- # MakeMaker convention for undefined $VERSION:
- next unless $mod->inst_version eq "undef";
- print "No VERSION in ", $mod->id, "\n";
- }
-
- # find out which distribution on CPAN contains a module:
- print CPAN::Shell->expand("Module","Apache::Constants")->cpan_file
-
-Or if you want to write a cronjob to watch The CPAN, you could list
-all modules that need updating. First a quick and dirty way:
-
- perl -e 'use CPAN; CPAN::Shell->r;'
-
-If you don't want to get any output in the case that all modules are
-up to date, you can parse the output of above command for the regular
-expression //modules are up to date// and decide to mail the output
-only if it doesn't match. Ick?
-
-If you prefer to do it more in a programmer style in one single
-process, maybe something like this suits you better:
-
- # list all modules on my disk that have newer versions on CPAN
- for $mod (CPAN::Shell->expand("Module","/./")){
- next unless $mod->inst_file;
- next if $mod->uptodate;
- printf "Module %s is installed as %s, could be updated to %s from CPAN\n",
- $mod->id, $mod->inst_version, $mod->cpan_version;
- }
-
-If that gives you too much output every day, you maybe only want to
-watch for three modules. You can write
-
- for $mod (CPAN::Shell->expand("Module","/Apache|LWP|CGI/")){
-
-as the first line instead. Or you can combine some of the above
-tricks:
-
- # watch only for a new mod_perl module
- $mod = CPAN::Shell->expand("Module","mod_perl");
- exit if $mod->uptodate;
- # new mod_perl arrived, let me know all update recommendations
- CPAN::Shell->r;
-

-=head2 Methods in the other Classes
-
-The programming interface for the classes CPAN::Module,
-CPAN::Distribution, CPAN::Bundle, and CPAN::Author is still considered
-beta and partially even alpha. In the following paragraphs only those
-methods are documented that have proven useful over a longer time and
-thus are unlikely to change.

-
-=item CPAN::Bundle::force($method,@args)
-
-Forces CPAN to perform a task that normally would have failed. Force
-takes as arguments a method name to be called and any number of
-additional arguments that should be passed to the called method. The
-internals of the object get the needed changes so that CPAN.pm does
-not refuse to take the action. The C<force> is passed recursively to
-all contained objects.
-
-=item CPAN::Bundle::get()
-
-Recursively runs the C<get> method on all items contained in the bundle
-
-=item CPAN::Bundle::inst_file()
-
-Returns the highest installed version of the bundle in either @INC or
-C<$CPAN::Config->{cpan_home}>. Note that this is different from
-CPAN::Module::inst_file.
-
-=item CPAN::Bundle::inst_version()
-
-Like CPAN::Bundle::inst_file, but returns the $VERSION

-runs C<make clean> there.
-
-=item CPAN::Distribution::containsmods()
-
-Returns a list of IDs of modules contained in a distribution file.
-Only works for distributions listed in the 02packages.details.txt.gz
-file. This typically means that only the most recent version of a
-distribution is covered.
-
-=item CPAN::Distribution::cvs_import()
-
-Changes to the directory where the distribution has been unpacked and
-runs something like
-
- cvs -d $cvs_root import -m $cvs_log $cvs_dir $userid v$version
-
-there.
-
-=item CPAN::Distribution::dir()
-
-Returns the directory into which this distribution has been unpacked.
-
-=item CPAN::Distribution::force($method,@args)
-
-Forces CPAN to perform a task that normally would have failed. Force
-takes as arguments a method name to be called and any number of
-additional arguments that should be passed to the called method. The
-internals of the object get the needed changes so that CPAN.pm does
-not refuse to take the action.
-
-=item CPAN::Distribution::get()
-
-Downloads the distribution from CPAN and unpacks it. Does nothing if
-the distribution has already been downloaded and unpacked within the
-current session.
-
-=item CPAN::Distribution::install()
-
-Changes to the directory where the distribution has been unpacked and
-runs the external command C<make install> there. If C<make> has not
-yet been run, it will be run first. A C<make test> will be issued in
-any case and if this fails, the install will be cancelled. The
-cancellation can be avoided by letting C<force> run the C<install> for
-you.
-
-=item CPAN::Distribution::isa_perl()
-
-Returns 1 if this distribution file seems to be a perl distribution.
-Normally this is derived from the file name only, but the index from
-CPAN can contain a hint to achieve a return value of true for other
-filenames too.
-
-=item CPAN::Distribution::look()
-
-Changes to the directory where the distribution has been unpacked and
-opens a subshell there. Exiting the subshell returns.
-
-=item CPAN::Distribution::make()
-
-First runs the C<get> method to make sure the distribution is
-downloaded and unpacked. Changes to the directory where the
-distribution has been unpacked and runs the external commands C<perl
-Makefile.PL> and C<make> there.
-
-=item CPAN::Distribution::prereq_pm()
-
-Returns the hash reference that has been announced by a distribution
-as the PREREQ_PM hash in the Makefile.PL. Note: works only after an
-attempt has been made to C<make> the distribution. Returns undef
-otherwise.
-
-=item CPAN::Distribution::readme()
-
-Downloads the README file associated with a distribution and runs it
-through the pager specified in C<$CPAN::Config->{pager}>.
-
-=item CPAN::Distribution::test()
-
-Changes to the directory where the distribution has been unpacked and
-runs C<make test> there.

-=item CPAN::Distribution::uptodate()
-
-Returns 1 if all the modules contained in the distribution are
-uptodate. Relies on containsmods.
-
-=item CPAN::Index::force_reload()

-Forces a reload of all indices.
-
-=item CPAN::Index::reload()
-
-Reloads all indices if they have been read more than
-C<$CPAN::Config->{index_expire}> days.
-
-=item CPAN::InfoObj::dump()
-
-CPAN::Author, CPAN::Bundle, CPAN::Module, and CPAN::Distribution
-inherit this method. It prints the data structure associated with an
-object. Useful for debugging. Note: the data structure is considered
-internal and thus subject to change without notice.
-
-=item CPAN::Module::as_glimpse()
-
-Returns a one-line description of the module
-
-=item CPAN::Module::as_string()
-
-Returns a multi-line description of the module

-=item CPAN::Module::cvs_import()
-
-Runs a cvs_import on the distribution associated with this module.
-
-=item CPAN::Module::description()
-
-Returns a 44 chracter description of this module. Only available for
-modules listed in The Module List (CPAN/modules/00modlist.long.html
-or 00modlist.long.txt.gz)
-
-=item CPAN::Module::force($method,@args)
-
-Forces CPAN to perform a task that normally would have failed. Force
-takes as arguments a method name to be called and any number of
-additional arguments that should be passed to the called method. The
-internals of the object get the needed changes so that CPAN.pm does
-not refuse to take the action.
-
-=item CPAN::Module::get()
-
-Runs a get on the distribution associated with this module.
-
-=item CPAN::Module::inst_file()
-
-Returns the filename of the module found in @INC. The first file found
-is reported just like perl itself stops searching @INC when it finds a
-module.
-
-=item CPAN::Module::inst_version()
-

-
-=head2 Cache Manager
-
-Currently the cache manager only keeps track of the build directory
-($CPAN::Config->{build_dir}). It is a simple FIFO mechanism that
-deletes complete directories below C<build_dir> as soon as the size of
-all directories there gets bigger than $CPAN::Config->{build_cache}
-(in MB). The contents of this cache may be used for later
-re-installations that you intend to do manually, but will never be
-trusted by CPAN itself. This is due to the fact that the user might
-use these directories for building modules on different architectures.
-
-There is another directory ($CPAN::Config->{keep_source_where}) where
-the original distribution files are kept. This directory is not
-covered by the cache manager and must be controlled by the user. If
-you choose to have the same directory as build_dir and as
-keep_source_where directory, then your sources will be deleted with
-the same fifo mechanism.
-
-=head2 Bundles
-
-A bundle is just a perl module in the namespace Bundle:: that does not
-define any functions or methods. It usually only contains documentation.
-
-It starts like a perl module with a package declaration and a $VERSION
-variable. After that the pod section looks like any other pod with the
-only difference being that I<one special pod section> exists starting with
-(verbatim):
-
- =head1 CONTENTS
-
-In this pod section each line obeys the format
-
- Module_Name [Version_String] [- optional text]
-
-The only required part is the first field, the name of a module
-(e.g. Foo::Bar, ie. I<not> the name of the distribution file). The rest
-of the line is optional. The comment part is delimited by a dash just
-as in the man page header.
-
-The distribution of a bundle should follow the same convention as
-other distributions.
-
-Bundles are treated specially in the CPAN package. If you say 'install
-Bundle::Tkkit' (assuming such a bundle exists), CPAN will install all
-the modules in the CONTENTS section of the pod. You can install your
-own Bundles locally by placing a conformant Bundle file somewhere into
-your @INC path. The autobundle() command which is available in the
-shell interface does that for you by including all currently installed
-modules in a snapshot bundle file.
-
-=head2 Prerequisites
-
-If you have a local mirror of CPAN and can access all files with
-"file:" URLs, then you only need a perl better than perl5.003 to run
-this module. Otherwise Net::FTP is strongly recommended. LWP may be
-required for non-UNIX systems or if your nearest CPAN site is
-associated with an URL that is not C<ftp:>.
-
-If you have neither Net::FTP nor LWP, there is a fallback mechanism
-implemented for an external ftp command or for an external lynx
-command.
-
-=head2 Finding packages and VERSION
-
-This module presumes that all packages on CPAN
-
-=over 2
-
-=item *
-
-declare their $VERSION variable in an easy to parse manner. This
-prerequisite can hardly be relaxed because it consumes far too much
-memory to load all packages into the running program just to determine
-the $VERSION variable. Currently all programs that are dealing with
-version use something like this
-
- perl -MExtUtils::MakeMaker -le \
- 'print MM->parse_version(shift)' filename
-
-If you are author of a package and wonder if your $VERSION can be
-parsed, please try the above method.
-
-=item *
-
-come as compressed or gzipped tarfiles or as zip files and contain a
-Makefile.PL (well, we try to handle a bit more, but without much
-enthusiasm).
-
-=back
-
-=head2 Debugging
-
-The debugging of this module is a bit complex, because we have
-interferences of the software producing the indices on CPAN, of the
-mirroring process on CPAN, of packaging, of configuration, of
-synchronicity, and of bugs within CPAN.pm.
-
-For code debugging in interactive mode you can try "o debug" which
-will list options for debugging the various parts of the code. You
-should know that "o debug" has built-in completion support.
-
-For data debugging there is the C<dump> command which takes the same
-arguments as make/test/install and outputs the object's Data::Dumper
-dump.
-
-=head2 Floppy, Zip, Offline Mode
-
-CPAN.pm works nicely without network too. If you maintain machines
-that are not networked at all, you should consider working with file:
-URLs. Of course, you have to collect your modules somewhere first. So
-you might use CPAN.pm to put together all you need on a networked
-machine. Then copy the $CPAN::Config->{keep_source_where} (but not
-$CPAN::Config->{build_dir}) directory on a floppy. This floppy is kind
-of a personal CPAN. CPAN.pm on the non-networked machines works nicely
-with this floppy. See also below the paragraph about CD-ROM support.
-
-=head1 CONFIGURATION
-
-When the CPAN module is installed, a site wide configuration file is
-created as CPAN/Config.pm. The default values defined there can be
-overridden in another configuration file: CPAN/MyConfig.pm. You can
-store this file in $HOME/.cpan/CPAN/MyConfig.pm if you want, because
-$HOME/.cpan is added to the search path of the CPAN module before the
-use() or require() statements.
-
-Currently the following keys in the hash reference $CPAN::Config are
-defined:
-
- build_cache size of cache for directories to build modules
- build_dir locally accessible directory to build modules
- index_expire after this many days refetch index files
- cache_metadata use serializer to cache metadata
- cpan_home local directory reserved for this package
- dontload_hash anonymous hash: modules in the keys will not be
- loaded by the CPAN::has_inst() routine
- gzip location of external program gzip
- inactivity_timeout breaks interactive Makefile.PLs after this
- many seconds inactivity. Set to 0 to never break.
- inhibit_startup_message
- if true, does not print the startup message
- keep_source_where directory in which to keep the source (if we do)
- make location of external make program
- make_arg arguments that should always be passed to 'make'
- make_install_arg same as make_arg for 'make install'
- makepl_arg arguments passed to 'perl Makefile.PL'
- pager location of external program more (or any pager)
- prerequisites_policy
- what to do if you are missing module prerequisites
- ('follow' automatically, 'ask' me, or 'ignore')
- proxy_user username for accessing an authenticating proxy
- proxy_pass password for accessing an authenticating proxy
- scan_cache controls scanning of cache ('atstart' or 'never')
- tar location of external program tar
- term_is_latin if true internal UTF-8 is translated to ISO-8859-1
- (and nonsense for characters outside latin range)
- unzip location of external program unzip
- urllist arrayref to nearby CPAN sites (or equivalent locations)
- wait_list arrayref to a wait server to try (See CPAN::WAIT)
- ftp_proxy, } the three usual variables for configuring
- http_proxy, } proxy requests. Both as CPAN::Config variables
- no_proxy } and as environment variables configurable.
-
-You can set and query each of these options interactively in the cpan
-shell with the command set defined within the C<o conf> command:
-
-=over 2
-
-=item C<o conf E<lt>scalar optionE<gt>>
-
-prints the current value of the I<scalar option>
-
-=item C<o conf E<lt>scalar optionE<gt> E<lt>valueE<gt>>
-
-Sets the value of the I<scalar option> to I<value>
-
-=item C<o conf E<lt>list optionE<gt>>
-
-prints the current value of the I<list option> in MakeMaker's
-neatvalue format.
-
-=item C<o conf E<lt>list optionE<gt> [shift|pop]>
-
-shifts or pops the array in the I<list option> variable
-
-=item C<o conf E<lt>list optionE<gt> [unshift|push|splice] E<lt>listE<gt>>
-
-works like the corresponding perl commands.
-
-=back
-
-=head2 Note on urllist parameter's format
-
-urllist parameters are URLs according to RFC 1738. We do a little
-guessing if your URL is not compliant, but if you have problems with
-file URLs, please try the correct format. Either:
-
- file://localhost/whatever/ftp/pub/CPAN/
-
-or
-
- file:///home/ftp/pub/CPAN/
-
-=head2 urllist parameter has CD-ROM support
-
-The C<urllist> parameter of the configuration table contains a list of
-URLs that are to be used for downloading. If the list contains any
-C<file> URLs, CPAN always tries to get files from there first. This
-feature is disabled for index files. So the recommendation for the
-owner of a CD-ROM with CPAN contents is: include your local, possibly
-outdated CD-ROM as a C<file> URL at the end of urllist, e.g.
-
- o conf urllist push file://localhost/CDROM/CPAN
-
-CPAN.pm will then fetch the index files from one of the CPAN sites
-that come at the beginning of urllist. It will later check for each
-module if there is a local copy of the most recent version.
-
-Another peculiarity of urllist is that the site that we could
-successfully fetch the last file from automatically gets a preference
-token and is tried as the first site for the next request. So if you
-add a new site at runtime it may happen that the previously preferred
-site will be tried another time. This means that if you want to disallow
-a site for the next transfer, it must be explicitly removed from
-urllist.
-
-=head1 SECURITY
-
-There's no strong security layer in CPAN.pm. CPAN.pm helps you to
-install foreign, unmasked, unsigned code on your machine. We compare
-to a checksum that comes from the net just as the distribution file
-itself. If somebody has managed to tamper with the distribution file,
-they may have as well tampered with the CHECKSUMS file. Future
-development will go towards strong authentication.
-
-=head1 EXPORT
-
-Most functions in package CPAN are exported per default. The reason
-for this is that the primary use is intended for the cpan shell or for
-oneliners.
-
-=head1 POPULATE AN INSTALLATION WITH LOTS OF MODULES
-
-Populating a freshly installed perl with my favorite modules is pretty
-easy if you maintain a private bundle definition file. To get a useful
-blueprint of a bundle definition file, the command autobundle can be used
-on the CPAN shell command line. This command writes a bundle definition
-file for all modules that are installed for the currently running perl
-interpreter. It's recommended to run this command only once and from then
-on maintain the file manually under a private name, say
-Bundle/my_bundle.pm. With a clever bundle file you can then simply say
-
- cpan> install Bundle::my_bundle
-
-then answer a few questions and then go out for a coffee.
-
-Maintaining a bundle definition file means keeping track of two
-things: dependencies and interactivity. CPAN.pm sometimes fails on
-calculating dependencies because not all modules define all MakeMaker
-attributes correctly, so a bundle definition file should specify
-prerequisites as early as possible. On the other hand, it's a bit
-annoying that many distributions need some interactive configuring. So
-what I try to accomplish in my private bundle file is to have the
-packages that need to be configured early in the file and the gentle
-ones later, so I can go out after a few minutes and leave CPAN.pm
-untended.
-
-=head1 WORKING WITH CPAN.pm BEHIND FIREWALLS
-
-Thanks to Graham Barr for contributing the following paragraphs about
-the interaction between perl, and various firewall configurations. For
-further informations on firewalls, it is recommended to consult the
-documentation that comes with the ncftp program. If you are unable to
-go through the firewall with a simple Perl setup, it is very likely
-that you can configure ncftp so that it works for your firewall.
-
-=head2 Three basic types of firewalls
-
-Firewalls can be categorized into three basic types.
-
-=over
-
-=item http firewall
-
-This is where the firewall machine runs a web server and to access the
-outside world you must do it via the web server. If you set environment
-variables like http_proxy or ftp_proxy to a values beginning with http://
-or in your web browser you have to set proxy information then you know
-you are running a http firewall.
-
-To access servers outside these types of firewalls with perl (even for
-ftp) you will need to use LWP.
-
-=item ftp firewall
-
-This where the firewall machine runs a ftp server. This kind of
-firewall will only let you access ftp servers outside the firewall.
-This is usually done by connecting to the firewall with ftp, then
-entering a username like "user@outside.host.com"
-
-To access servers outside these type of firewalls with perl you
-will need to use Net::FTP.
-
-=item One way visibility
-
-I say one way visibility as these firewalls try to make themselve look
-invisible to the users inside the firewall. An FTP data connection is
-normally created by sending the remote server your IP address and then
-listening for the connection. But the remote server will not be able to
-connect to you because of the firewall. So for these types of firewall
-FTP connections need to be done in a passive mode.
-
-There are two that I can think off.
-
-=over
-
-=item SOCKS
-
-If you are using a SOCKS firewall you will need to compile perl and link
-it with the SOCKS library, this is what is normally called a 'socksified'
-perl. With this executable you will be able to connect to servers outside
-the firewall as if it is not there.
-
-=item IP Masquerade
-
-This is the firewall implemented in the Linux kernel, it allows you to
-hide a complete network behind one IP address. With this firewall no
-special compiling is needed as you can access hosts directly.
-
-=back
-
-=back
-
-=head2 Configuring lynx or ncftp for going through a firewall
-
-If you can go through your firewall with e.g. lynx, presumably with a
-command such as
-
- /usr/local/bin/lynx -pscott:tiger
-
-then you would configure CPAN.pm with the command
-
- o conf lynx "/usr/local/bin/lynx -pscott:tiger"
-
-That's all. Similarly for ncftp or ftp, you would configure something
-like
-
- o conf ncftp "/usr/bin/ncftp -f /home/scott/ncftplogin.cfg"
-
-Your milage may vary...
-
-=head1 FAQ
-
-=over
-
-=item 1)
-
-I installed a new version of module X but CPAN keeps saying,
-I have the old version installed
-
-Most probably you B<do> have the old version installed. This can
-happen if a module installs itself into a different directory in the
-@INC path than it was previously installed. This is not really a
-CPAN.pm problem, you would have the same problem when installing the
-module manually. The easiest way to prevent this behaviour is to add
-the argument C<UNINST=1> to the C<make install> call, and that is why
-many people add this argument permanently by configuring
-
- o conf make_install_arg UNINST=1
-
-=item 2)
-
-So why is UNINST=1 not the default?
-
-Because there are people who have their precise expectations about who
-may install where in the @INC path and who uses which @INC array. In
-fine tuned environments C<UNINST=1> can cause damage.
-
-=item 3)
-
-I want to clean up my mess, and install a new perl along with
-all modules I have. How do I go about it?
-
-Run the autobundle command for your old perl and optionally rename the
-resulting bundle file (e.g. Bundle/mybundle.pm), install the new perl
-with the Configure option prefix, e.g.
-
- ./Configure -Dprefix=/usr/local/perl-5.6.78.9
-
-Install the bundle file you produced in the first step with something like
-
- cpan> install Bundle::mybundle
-
-and you're done.
-
-=item 4)
-
-When I install bundles or multiple modules with one command
-there is too much output to keep track of.
-
-You may want to configure something like
-
- o conf make_arg "| tee -ai /root/.cpan/logs/make.out"
- o conf make_install_arg "| tee -ai /root/.cpan/logs/make_install.out"
-
-so that STDOUT is captured in a file for later inspection.
-
-
-=item 5)
-
-I am not root, how can I install a module in a personal directory?
-
-You will most probably like something like this:
-
- o conf makepl_arg "LIB=~/myperl/lib \
- INSTALLMAN1DIR=~/myperl/man/man1 \
- INSTALLMAN3DIR=~/myperl/man/man3"
- install Sybase::Sybperl
-
-You can make this setting permanent like all C<o conf> settings with
-C<o conf commit>.
-
-You will have to add ~/myperl/man to the MANPATH environment variable
-and also tell your perl programs to look into ~/myperl/lib, e.g. by
-including
-
- use lib "$ENV{HOME}/myperl/lib";
-
-or setting the PERL5LIB environment variable.
-
-Another thing you should bear in mind is that the UNINST parameter
-should never be set if you are not root.
-
-=item 6)
-
-How to get a package, unwrap it, and make a change before building it?
-
- look Sybase::Sybperl
-
-=item 7)
-
-I installed a Bundle and had a couple of fails. When I
-retried, everything resolved nicely. Can this be fixed to work
-on first try?
-
-The reason for this is that CPAN does not know the dependencies of all
-modules when it starts out. To decide about the additional items to
-install, it just uses data found in the generated Makefile. An
-undetected missing piece breaks the process. But it may well be that
-your Bundle installs some prerequisite later than some depending item
-and thus your second try is able to resolve everything. Please note,
-CPAN.pm does not know the dependency tree in advance and cannot sort
-the queue of things to install in a topologically correct order. It
-resolves perfectly well IFF all modules declare the prerequisites
-correctly with the PREREQ_PM attribute to MakeMaker. For bundles which
-fail and you need to install often, it is recommended sort the Bundle
-definition file manually. It is planned to improve the metadata
-situation for dependencies on CPAN in general, but this will still
-take some time.
-
-=item 8)
-
-In our intranet we have many modules for internal use. How
-can I integrate these modules with CPAN.pm but without uploading
-the modules to CPAN?
-
-Have a look at the CPAN::Site module.
-
-=item 9)
-
-When I run CPAN's shell, I get error msg about line 1 to 4,
-setting meta input/output via the /etc/inputrc file.
-
-Some versions of readline are picky about capitalization in the
-/etc/inputrc file and specifically RedHat 6.2 comes with a
-/etc/inputrc that contains the word C<on> in lowercase. Change the
-occurrences of C<on> to C<On> and the bug should disappear.
-
-=item 10)
-
-Some authors have strange characters in their names.
-
-Internally CPAN.pm uses the UTF-8 charset. If your terminal is
-expecting ISO-8859-1 charset, a converter can be activated by setting
-term_is_latin to a true value in your config file. One way of doing so
-would be
-
- cpan> ! $CPAN::Config->{term_is_latin}=1
-
-Extended support for converters will be made available as soon as perl
-becomes stable with regard to charset issues.

-
-=head1 BUGS
-
-We should give coverage for B<all> of the CPAN and not just the PAUSE
-part, right? In this discussion CPAN and PAUSE have become equal --
-but they are not. PAUSE is authors/, modules/ and scripts/. CPAN is
-PAUSE plus the clpa/, doc/, misc/, ports/, and src/.
-
-Future development should be directed towards a better integration of
-the other parts.
-
-If a Makefile.PL requires special customization of libraries, prompts
-the user for special input, etc. then you may find CPAN is not able to
-build the distribution. In that case, you should attempt the
-traditional method of building a Perl module package from a shell.
