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 - -use vars qw{ @All }; - -# CPAN::Queue::new ; -sub new { - my($class,$s) = @_; - my $self = bless { qmod => $s }, $class; - push @All, $self; - return $self; -} - -# CPAN::Queue::first ; -sub first { - my $obj = $All[0]; - $obj->{qmod}; -} - -# CPAN::Queue::delete_first ; -sub delete_first { - my($class,$what) = @_; - my $i; - for my $i (0..$#All) { - if ( $All[$i]->{qmod} eq $what ) { - splice @All, $i, 1; - return; - } - } -} - -# CPAN::Queue::jumpqueue ; -sub jumpqueue { - my $class = shift; - my @what = @_; - CPAN->debug(sprintf("before jumpqueue All[%s] what[%s]", - join(",",map {$_->{qmod}} @All), - join(",",@what) - )) if $CPAN::DEBUG; - WHAT: for my $what (reverse @what) { - my $jumped = 0; - for (my $i=0; $i<$#All;$i++) { #prevent deep recursion - CPAN->debug("i[$All[$i]]what[$what]") if $CPAN::DEBUG; - if ($All[$i]->{qmod} eq $what){ - $jumped++; - if ($jumped > 100) { # one's OK if e.g. just - # processing now; more are OK if - # user typed it several times - $CPAN::Frontend->mywarn( -qq{Object [$what] queued more than 100 times, ignoring} - ); - next WHAT; - } - } - } - my $obj = bless { qmod => $what }, $class; - unshift @All, $obj; - } - CPAN->debug(sprintf("after jumpqueue All[%s] what[%s]", - join(",",map {$_->{qmod}} @All), - join(",",@what) - )) if $CPAN::DEBUG; -} - -# CPAN::Queue::exists ; -sub exists { - my($self,$what) = @_; - my @all = map { $_->{qmod} } @All; - my $exists = grep { $_->{qmod} eq $what } @All; - # warn "in exists what[$what] all[@all] exists[$exists]"; - $exists; -} - -# CPAN::Queue::delete ; -sub delete { - my($self,$mod) = @_; - @All = grep { $_->{qmod} ne $mod } @All; -} - -# CPAN::Queue::nullify_queue ; -sub nullify_queue { - @All = (); -} - - - -package CPAN; - -$META ||= CPAN->new; # In case we re-eval ourselves we need the || - -# from here on only subs. -################################################################################ - -#-> sub CPAN::all_objects ; -sub all_objects { - my($mgr,$class) = @_; - CPAN::Config->load unless $CPAN::Config_loaded++; - CPAN->debug("mgr[$mgr] class[$class]") if $CPAN::DEBUG; - CPAN::Index->reload; - values %{ $META->{readwrite}{$class} }; # unsafe meta access, ok -} -*all = \&all_objects; - -# Called by shell, not in batch mode.

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; - -=back - -=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.

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.

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. - -=back - -=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. - -=head1 AUTHOR - -Andreas Koenig E<lt>andreas.koenig@anima.deE<gt> - -=head1 TRANSLATIONS - -Kawai,Takanori provides a Japanese translation of this manpage at -http://member.nifty.ne.jp/hippo2000/perltips/CPAN.htm - -=head1 SEE ALSO - -perl(1), CPAN::Nox(3) - -=cut - |
