|

352 |
|
---|
353 | # CPAN::Queue is the package where the queue is maintained. Dependencies
|
---|
354 | # often have high priority and must be brought to the head of the queue,
|
---|
355 | # possibly by jumping the queue if they are already there. My first code
|
---|
356 | # attempt tried to be extremely correct. Whenever a module needed
|
---|
357 | # immediate treatment, I either unshifted it to the front of the queue,
|
---|
358 | # or, if it was already in the queue, I spliced and let it bypass the
|
---|
359 | # others. This became a too correct model that made it impossible to put
|
---|
360 | # an item more than once into the queue. Why would you need that? Well,
|
---|
361 | # you need temporary duplicates as the manager of the queue is a loop
|
---|
362 | # that
|
---|
363 | #
|
---|
364 | # (1) looks at the first item in the queue without shifting it off
|
---|
365 | #
|
---|
366 | # (2) cares for the item
|
---|
367 | #
|
---|
368 | # (3) removes the item from the queue, *even if its agenda failed and
|
---|
369 | # even if the item isn't the first in the queue anymore* (that way
|
---|
370 | # protecting against never ending queues)
|
---|
371 | #
|
---|
372 | # So if an item has prerequisites, the installation fails now, but we
|
---|
373 | # want to retry later. That's easy if we have it twice in the queue.
|
---|
374 | #
|
---|
375 | # I also expect insane dependency situations where an item gets more
|
---|
376 | # than two lives in the queue. Simplest example is triggered by 'install
|
---|
377 | # Foo Foo Foo'. People make this kind of mistakes and I don't want to

6011 | =head1 STATUS
|
---|
6012 |
|
---|
6013 | This module will eventually be replaced by CPANPLUS. CPANPLUS is kind
|
---|
6014 | of a modern rewrite from ground up with greater extensibility and more
|
---|
6015 | features but no full compatibility. If you're new to CPAN.pm, you
|
---|
6016 | probably should investigate if CPANPLUS is the better choice for you.
|
---|
6017 | If you're already used to CPAN.pm you're welcome to continue using it,
|
---|
6018 | if you accept that its development is mostly (though not completely)
|
---|
6019 | stalled.

|
---|
6021 | =head1 DESCRIPTION
|
---|
6022 |
|
---|
6023 | The CPAN module is designed to automate the make and install of perl
|
---|
6024 | modules and extensions. It includes some primitive searching capabilities and
|
---|
6025 | knows how to use Net::FTP or LWP (or lynx or an external ftp client)
|
---|
6026 | to fetch the raw data from the net.
|
---|
6027 |
|
---|
6028 | Modules are fetched from one or more of the mirrored CPAN
|
---|
6029 | (Comprehensive Perl Archive Network) sites and unpacked in a dedicated
|
---|
6030 | directory.
|
---|
6031 |
|
---|
6032 | The CPAN module also supports the concept of named and versioned
|
---|
6033 | I<bundles> of modules. Bundles simplify the handling of sets of
|
---|
6034 | related modules. See Bundles below.
|
---|
6035 |
|
---|
6036 | The package contains a session manager and a cache manager. There is
|
---|
6037 | no status retained between sessions. The session manager keeps track
|
---|
6038 | of what has been fetched, built and installed in the current
|
---|
6039 | session. The cache manager keeps track of the disk space occupied by
|
---|
6040 | the make processes and deletes excess space according to a simple FIFO
|
---|
6041 | mechanism.
|
---|
6042 |
|
---|
6043 | For extended searching capabilities there's a plugin for CPAN available,
|
---|
6044 | L<C<CPAN::WAIT>|CPAN::WAIT>. C<CPAN::WAIT> is a full-text search engine
|
---|
6045 | that indexes all documents available in CPAN authors directories. If
|
---|
6046 | C<CPAN::WAIT> is installed on your system, the interactive shell of
|
---|
6047 | CPAN.pm will enable the C<wq>, C<wr>, C<wd>, C<wl>, and C<wh> commands
|
---|
6048 | which send queries to the WAIT server that has been configured for your
|
---|
6049 | installation.
|
---|
6050 |
|
---|
6051 | All other methods provided are accessible in a programmer style and in an
|
---|
6052 | interactive shell style.
|
---|
6053 |
|
---|
6054 | =head2 Interactive Mode
|
---|
6055 |
|
---|
6056 | The interactive mode is entered by running
|
---|
6057 |
|
---|
6058 | perl -MCPAN -e shell
|
---|
6059 |
|
---|
6060 | which puts you into a readline interface. You will have the most fun if
|
---|
6061 | you install Term::ReadKey and Term::ReadLine to enjoy both history and
|
---|
6062 | command completion.
|
---|
6063 |
|
---|
6064 | Once you are on the command line, type 'h' and the rest should be
|
---|
6065 | self-explanatory.
|
---|
6066 |
|
---|
6067 | The function call C<shell> takes two optional arguments, one is the
|
---|
6068 | prompt, the second is the default initial command line (the latter
|
---|
6069 | only works if a real ReadLine interface module is installed).
|
---|
6070 |
|
---|
6071 | The most common uses of the interactive modes are
|
---|
6072 |
|
---|
6073 | =over 2
|
---|
6074 |
|
---|
6075 | =item Searching for authors, bundles, distribution files and modules
|
---|
6076 |
|
---|
6077 | There are corresponding one-letter commands C<a>, C<b>, C<d>, and C<m>
|
---|
6078 | for each of the four categories and another, C<i> for any of the
|
---|
6079 | mentioned four. Each of the four entities is implemented as a class
|
---|
6080 | with slightly differing methods for displaying an object.
|
---|
6081 |
|
---|
6082 | Arguments you pass to these commands are either strings exactly matching
|
---|
6083 | the identification string of an object or regular expressions that are
|
---|
6084 | then matched case-insensitively against various attributes of the
|
---|
6085 | objects. The parser recognizes a regular expression only if you
|
---|
6086 | enclose it between two slashes.
|
---|
6087 |
|
---|
6088 | The principle is that the number of found objects influences how an
|
---|
6089 | item is displayed. If the search finds one item, the result is
|
---|
6090 | displayed with the rather verbose method C<as_string>, but if we find
|
---|
6091 | more than one, we display each object with the terse method
|
---|
6092 | <as_glimpse>.
|
---|
6093 |
|
---|
6094 | =item make, test, install, clean modules or distributions
|
---|
6095 |
|
---|
6096 | These commands take any number of arguments and investigate what is
|
---|
6097 | necessary to perform the action. If the argument is a distribution
|
---|
6098 | file name (recognized by embedded slashes), it is processed. If it is
|
---|
6099 | a module, CPAN determines the distribution file in which this module
|
---|
6100 | is included and processes that, following any dependencies named in
|
---|
6101 | the module's Makefile.PL (this behavior is controlled by
|
---|
6102 | I<prerequisites_policy>.)
|
---|
6103 |
|
---|
6104 | Any C<make> or C<test> are run unconditionally. An
|
---|
6105 |
|
---|
6106 | install <distribution_file>
|
---|
6107 |
|
---|
6108 | also is run unconditionally. But for
|
---|
6109 |
|
---|
6110 | install <module>
|
---|
6111 |
|
---|
6112 | CPAN checks if an install is actually needed for it and prints
|
---|
6113 | I<module up to date> in the case that the distribution file containing
|
---|
6114 | the module doesn't need to be updated.
|
---|
6115 |
|
---|
6116 | CPAN also keeps track of what it has done within the current session
|
---|
6117 | and doesn't try to build a package a second time regardless if it
|
---|
6118 | succeeded or not. The C<force> command takes as a first argument the
|
---|
6119 | method to invoke (currently: C<make>, C<test>, or C<install>) and executes the
|
---|
6120 | command from scratch.
|
---|
6121 |
|
---|
6122 | Example:
|
---|
6123 |
|
---|
6124 | cpan> install OpenGL
|
---|
6125 | OpenGL is up to date.
|
---|
6126 | cpan> force install OpenGL
|
---|
6127 | Running make
|
---|
6128 | OpenGL-0.4/
|
---|
6129 | OpenGL-0.4/COPYRIGHT
|
---|
6130 | [...]
|
---|
6131 |
|
---|
6132 | A C<clean> command results in a
|
---|
6133 |
|
---|
6134 | make clean
|
---|
6135 |
|
---|
6136 | being executed within the distribution file's working directory.
|
---|
6137 |
|
---|
6138 | =item get, readme, look module or distribution
|
---|
6139 |
|
---|
6140 | C<get> downloads a distribution file without further action. C<readme>
|
---|
6141 | displays the README file of the associated distribution. C<Look> gets
|
---|
6142 | and untars (if not yet done) the distribution file, changes to the
|
---|
6143 | appropriate directory and opens a subshell process in that directory.
|
---|
6144 |
|
---|
6145 | =item ls author
|
---|
6146 |
|
---|
6147 | C<ls> lists all distribution files in and below an author's CPAN
|
---|
6148 | directory. Only those files that contain modules are listed and if
|
---|
6149 | there is more than one for any given module, only the most recent one
|
---|
6150 | is listed.
|
---|
6151 |
|
---|
6152 | =item Signals
|
---|
6153 |
|
---|
6154 | CPAN.pm installs signal handlers for SIGINT and SIGTERM. While you are
|
---|
6155 | in the cpan-shell it is intended that you can press C<^C> anytime and
|
---|
6156 | return to the cpan-shell prompt. A SIGTERM will cause the cpan-shell
|
---|
6157 | to clean up and leave the shell loop. You can emulate the effect of a
|
---|
6158 | SIGTERM by sending two consecutive SIGINTs, which usually means by
|
---|
6159 | pressing C<^C> twice.
|
---|
6160 |
|
---|
6161 | CPAN.pm ignores a SIGPIPE. If the user sets inactivity_timeout, a
|
---|
6162 | SIGALRM is used during the run of the C<perl Makefile.PL> subprocess.
|
---|
6163 |
|
---|

|
---|
6165 |
|
---|
6166 | =head2 CPAN::Shell
|
---|
6167 |
|
---|
6168 | The commands that are available in the shell interface are methods in
|
---|
6169 | the package CPAN::Shell. If you enter the shell command, all your
|
---|
6170 | input is split by the Text::ParseWords::shellwords() routine which
|
---|
6171 | acts like most shells do. The first word is being interpreted as the
|
---|
6172 | method to be called and the rest of the words are treated as arguments
|
---|
6173 | to this method. Continuation lines are supported if a line ends with a
|
---|
6174 | literal backslash.
|
---|
6175 |
|
---|
6176 | =head2 autobundle
|
---|
6177 |
|
---|
6178 | C<autobundle> writes a bundle file into the
|
---|
6179 | C<$CPAN::Config-E<gt>{cpan_home}/Bundle> directory. The file contains
|
---|
6180 | a list of all modules that are both available from CPAN and currently
|
---|
6181 | installed within @INC. The name of the bundle file is based on the
|
---|
6182 | current date and a counter.
|
---|
6183 |
|
---|
6184 | =head2 recompile
|
---|
6185 |
|
---|
6186 | recompile() is a very special command in that it takes no argument and
|
---|
6187 | runs the make/test/install cycle with brute force over all installed
|
---|
6188 | dynamically loadable extensions (aka XS modules) with 'force' in
|
---|
6189 | effect. The primary purpose of this command is to finish a network
|
---|
6190 | installation. Imagine, you have a common source tree for two different
|
---|
6191 | architectures. You decide to do a completely independent fresh
|
---|
6192 | installation. You start on one architecture with the help of a Bundle
|
---|
6193 | file produced earlier. CPAN installs the whole Bundle for you, but
|
---|
6194 | when you try to repeat the job on the second architecture, CPAN
|
---|
6195 | responds with a C<"Foo up to date"> message for all modules. So you
|
---|
6196 | invoke CPAN's recompile on the second architecture and you're done.
|
---|
6197 |
|
---|
6198 | Another popular use for C<recompile> is to act as a rescue in case your
|
---|
6199 | perl breaks binary compatibility. If one of the modules that CPAN uses
|
---|
6200 | is in turn depending on binary compatibility (so you cannot run CPAN
|
---|
6201 | commands), then you should try the CPAN::Nox module for recovery.
|
---|
6202 |
|
---|
6203 | =head2 The four C<CPAN::*> Classes: Author, Bundle, Module, Distribution
|
---|
6204 |
|
---|
6205 | Although it may be considered internal, the class hierarchy does matter
|
---|
6206 | for both users and programmer. CPAN.pm deals with above mentioned four
|
---|
6207 | classes, and all those classes share a set of methods. A classical
|
---|
6208 | single polymorphism is in effect. A metaclass object registers all
|
---|
6209 | objects of all kinds and indexes them with a string. The strings
|
---|
6210 | referencing objects have a separated namespace (well, not completely
|
---|
6211 | separated):
|
---|
6212 |
|
---|
6213 | Namespace Class
|
---|
6214 |
|
---|
6215 | words containing a "/" (slash) Distribution
|
---|
6216 | words starting with Bundle:: Bundle
|
---|
6217 | everything else Module or Author
|
---|
6218 |
|
---|
6219 | Modules know their associated Distribution objects. They always refer
|
---|
6220 | to the most recent official release. Developers may mark their releases
|
---|
6221 | as unstable development versions (by inserting an underbar into the
|
---|
6222 | module version number which will also be reflected in the distribution
|
---|
6223 | name when you run 'make dist'), so the really hottest and newest
|
---|
6224 | distribution is not always the default. If a module Foo circulates
|
---|
6225 | on CPAN in both version 1.23 and 1.23_90, CPAN.pm offers a convenient
|
---|
6226 | way to install version 1.23 by saying
|
---|
6227 |
|
---|
6228 | install Foo
|
---|
6229 |
|
---|
6230 | This would install the complete distribution file (say
|
---|
6231 | BAR/Foo-1.23.tar.gz) with all accompanying material. But if you would
|
---|
6232 | like to install version 1.23_90, you need to know where the
|
---|
6233 | distribution file resides on CPAN relative to the authors/id/
|
---|
6234 | directory. If the author is BAR, this might be BAR/Foo-1.23_90.tar.gz;
|
---|
6235 | so you would have to say
|
---|
6236 |
|
---|
6237 | install BAR/Foo-1.23_90.tar.gz
|
---|
6238 |
|
---|
6239 | The first example will be driven by an object of the class
|
---|
6240 | CPAN::Module, the second by an object of class CPAN::Distribution.
|
---|
6241 |
|
---|
6242 | =head2 Programmer's interface
|
---|
6243 |
|
---|
6244 | If you do not enter the shell, the available shell commands are both
|
---|
6245 | available as methods (C<CPAN::Shell-E<gt>install(...)>) and as
|
---|
6246 | functions in the calling package (C<install(...)>).
|
---|
6247 |
|
---|
6248 | There's currently only one class that has a stable interface -
|
---|
6249 | CPAN::Shell. All commands that are available in the CPAN shell are
|
---|
6250 | methods of the class CPAN::Shell. Each of the commands that produce
|
---|
6251 | listings of modules (C<r>, C<autobundle>, C<u>) also return a list of
|
---|
6252 | the IDs of all modules within the list.
|
---|
6253 |
|
---|
6254 | =over 2
|
---|
6255 |
|
---|
6256 | =item expand($type,@things)
|
---|
6257 |
|
---|
6258 | The IDs of all objects available within a program are strings that can
|
---|
6259 | be expanded to the corresponding real objects with the
|
---|
6260 | C<CPAN::Shell-E<gt>expand("Module",@things)> method. Expand returns a
|
---|
6261 | list of CPAN::Module objects according to the C<@things> arguments
|
---|
6262 | given. In scalar context it only returns the first element of the
|
---|
6263 | list.
|
---|
6264 |
|
---|
6265 | =item expandany(@things)
|
---|
6266 |
|
---|
6267 | Like expand, but returns objects of the appropriate type, i.e.
|
---|
6268 | CPAN::Bundle objects for bundles, CPAN::Module objects for modules and
|
---|
6269 | CPAN::Distribution objects fro distributions.
|
---|
6270 |
|
---|
6271 | =item Programming Examples
|
---|
6272 |
|
---|
6273 | This enables the programmer to do operations that combine
|
---|
6274 | functionalities that are available in the shell.
|
---|
6275 |
|
---|
6276 | # install everything that is outdated on my disk:
|
---|
6277 | perl -MCPAN -e 'CPAN::Shell->install(CPAN::Shell->r)'
|
---|
6278 |
|
---|
6279 | # install my favorite programs if necessary:
|
---|
6280 | for $mod (qw(Net::FTP Digest::MD5 Data::Dumper)){
|
---|
6281 | my $obj = CPAN::Shell->expand('Module',$mod);
|
---|
6282 | $obj->install;
|
---|
6283 | }
|
---|
6284 |
|
---|
6285 | # list all modules on my disk that have no VERSION number
|
---|
6286 | for $mod (CPAN::Shell->expand("Module","/./")){
|
---|
6287 | next unless $mod->inst_file;
|
---|
6288 | # MakeMaker convention for undefined $VERSION:
|
---|
6289 | next unless $mod->inst_version eq "undef";
|
---|
6290 | print "No VERSION in ", $mod->id, "\n";
|
---|
6291 | }
|
---|
6292 |
|
---|
6293 | # find out which distribution on CPAN contains a module:
|
---|
6294 | print CPAN::Shell->expand("Module","Apache::Constants")->cpan_file
|
---|
6295 |
|
---|
6296 | Or if you want to write a cronjob to watch The CPAN, you could list
|
---|
6297 | all modules that need updating. First a quick and dirty way:
|
---|
6298 |
|
---|
6299 | perl -e 'use CPAN; CPAN::Shell->r;'
|
---|
6300 |
|
---|
6301 | If you don't want to get any output in the case that all modules are
|
---|
6302 | up to date, you can parse the output of above command for the regular
|
---|
6303 | expression //modules are up to date// and decide to mail the output
|

6304 | only if it doesn't match. Ick?
|
---|
6305 |
|
---|
6306 | If you prefer to do it more in a programmer style in one single
|
---|
6307 | process, maybe something like this suits you better:
|
---|
6308 |
|
---|
6309 | # list all modules on my disk that have newer versions on CPAN
|
---|
6310 | for $mod (CPAN::Shell->expand("Module","/./")){
|
---|
6311 | next unless $mod->inst_file;
|
---|
6312 | next if $mod->uptodate;
|
---|
6313 | printf "Module %s is installed as %s, could be updated to %s from CPAN\n",
|
---|
6314 | $mod->id, $mod->inst_version, $mod->cpan_version;
|
---|
6315 | }
|
---|
6316 |
|
---|
6317 | If that gives you too much output every day, you maybe only want to
|
---|
6318 | watch for three modules. You can write
|
---|
6319 |
|
---|
6320 | for $mod (CPAN::Shell->expand("Module","/Apache|LWP|CGI/")){
|
---|
6321 |
|
---|
6322 | as the first line instead. Or you can combine some of the above
|
---|
6323 | tricks:
|
---|
6324 |
|
---|
6325 | # watch only for a new mod_perl module
|
---|
6326 | $mod = CPAN::Shell->expand("Module","mod_perl");
|
---|
6327 | exit if $mod->uptodate;
|

6328 | # new mod_perl arrived, let me know all update recommendations

6336 | CPAN::Distribution, CPAN::Bundle, and CPAN::Author is still considered
|
---|
6337 | beta and partially even alpha. In the following paragraphs only those

6382 | Forces CPAN to perform a task that normally would have failed. Force
|
---|
6383 | takes as arguments a method name to be called and any number of
|
---|
6384 | additional arguments that should be passed to the called method. The

|
---|
6439 | Only works for distributions listed in the 02packages.details.txt.gz
|
---|
6440 | file. This typically means that only the most recent version of a
|
---|
6441 | distribution is covered.
|
---|
6442 |
|
---|
6443 | =item CPAN::Distribution::cvs_import()
|
---|
6444 |
|

6464 | =item CPAN::Distribution::get()
|
---|
6465 |
|

---|
6471 |
|
---|
6472 | Changes to the directory where the distribution has been unpacked and
|
---|
6473 | runs the external command C<make install> there. If C<make> has not
|
---|
6474 | yet been run, it will be run first. A C<make test> will be issued in
|
---|
6475 | any case and if this fails, the install will be canceled. The
|
---|
6476 | cancellation can be avoided by letting C<force> run the C<install> for

---|
6477 | you.

6491 | =item CPAN::Distribution::make()
|
---|
6492 |
|
---|
6493 | First runs the C<get> method to make sure the distribution is

6627 | =head2 Cache Manager
|
---|
6628 |
|
---|
6629 | Currently the cache manager only keeps track of the build directory
|
---|
6630 | ($CPAN::Config->{build_dir}). It is a simple FIFO mechanism that
|
---|
6631 | deletes complete directories below C<build_dir> as soon as the size of
|
---|
6632 | all directories there gets bigger than $CPAN::Config->{build_cache}
|
---|
6633 | (in MB). The contents of this cache may be used for later
|
---|
6634 | re-installations that you intend to do manually, but will never be
|
---|
6635 | trusted by CPAN itself. This is due to the fact that the user might
|
---|
6636 | use these directories for building modules on different architectures.
|
---|
6637 |
|
---|
6638 | There is another directory ($CPAN::Config->{keep_source_where}) where
|
---|
6639 | the original distribution files are kept. This directory is not
|
---|
6640 | covered by the cache manager and must be controlled by the user. If
|
---|
6641 | you choose to have the same directory as build_dir and as
|
---|
6642 | keep_source_where directory, then your sources will be deleted with
|
---|
6643 | the same fifo mechanism.
|
---|
6644 |
|
---|
6645 | =head2 Bundles
|
---|
6646 |
|
---|
6647 | A bundle is just a perl module in the namespace Bundle:: that does not
|
---|
6648 | define any functions or methods. It usually only contains documentation.
|
---|
6649 |
|
---|
6650 | It starts like a perl module with a package declaration and a $VERSION
|
---|
6651 | variable. After that the pod section looks like any other pod with the
|
---|
6652 | only difference being that I<one special pod section> exists starting with
|
---|
6653 | (verbatim):
|
---|
6654 |
|
---|
6655 | =head1 CONTENTS
|
---|
6656 |
|
---|
6657 | In this pod section each line obeys the format
|
---|
6658 |
|
---|
6659 | Module_Name [Version_String] [- optional text]
|
---|
6660 |
|
---|
6661 | The only required part is the first field, the name of a module
|
---|
6662 | (e.g. Foo::Bar, ie. I<not> the name of the distribution file). The rest
|
---|
6663 | of the line is optional. The comment part is delimited by a dash just
|
---|
6664 | as in the man page header.
|
---|
6665 |
|
---|
6666 | The distribution of a bundle should follow the same convention as
|
---|
6667 | other distributions.
|
---|
6668 |
|
---|
6669 | Bundles are treated specially in the CPAN package. If you say 'install
|
---|
6670 | Bundle::Tkkit' (assuming such a bundle exists), CPAN will install all
|
---|
6671 | the modules in the CONTENTS section of the pod. You can install your
|
---|
6672 | own Bundles locally by placing a conformant Bundle file somewhere into
|
---|
6673 | your @INC path. The autobundle() command which is available in the
|
---|
6674 | shell interface does that for you by including all currently installed
|
---|
6675 | modules in a snapshot bundle file.
|
---|
6676 |
|
---|
6677 | =head2 Prerequisites
|
---|
6678 |
|
---|
6679 | If you have a local mirror of CPAN and can access all files with
|
---|
6680 | "file:" URLs, then you only need a perl better than perl5.003 to run
|
---|
6681 | this module. Otherwise Net::FTP is strongly recommended. LWP may be
|
---|
6682 | required for non-UNIX systems or if your nearest CPAN site is
|
---|
6683 | associated with a URL that is not C<ftp:>.
|
---|
6684 |
|
---|
6685 | If you have neither Net::FTP nor LWP, there is a fallback mechanism
|
---|
6686 | implemented for an external ftp command or for an external lynx
|
---|
6687 | command.
|
---|
6688 |
|
---|
6689 | =head2 Finding packages and VERSION
|
---|
6690 |
|
---|
6691 | This module presumes that all packages on CPAN
|
---|
6692 |
|
---|
6693 | =over 2
|
---|
6694 |
|
---|
6695 | =item *
|
---|
6696 |
|
---|
6697 | declare their $VERSION variable in an easy to parse manner. This
|
---|
6698 | prerequisite can hardly be relaxed because it consumes far too much
|
---|
6699 | memory to load all packages into the running program just to determine
|
---|
6700 | the $VERSION variable. Currently all programs that are dealing with
|
---|
6701 | version use something like this
|
---|
6702 |
|
---|
6703 | perl -MExtUtils::MakeMaker -le \
|
---|
6704 | 'print MM->parse_version(shift)' filename
|
---|
6705 |
|
---|
6706 | If you are author of a package and wonder if your $VERSION can be
|
---|
6707 | parsed, please try the above method.
|
---|
6708 |
|
---|
6709 | =item *
|
---|
6710 |
|
---|
6711 | come as compressed or gzipped tarfiles or as zip files and contain a
|
---|
6712 | Makefile.PL (well, we try to handle a bit more, but without much
|
---|
6713 | enthusiasm).

---|

|
---|
6717 | =head2 Debugging
|
---|
6718 |
|
---|
6719 | The debugging of this module is a bit complex, because we have
|
---|
6720 | interferences of the software producing the indices on CPAN, of the
|
---|
6721 | mirroring process on CPAN, of packaging, of configuration, of
|
---|
6722 | synchronicity, and of bugs within CPAN.pm.
|
---|
6723 |
|
---|
6724 | For code debugging in interactive mode you can try "o debug" which
|
---|
6725 | will list options for debugging the various parts of the code. You
|
---|
6726 | should know that "o debug" has built-in completion support.
|
---|
6727 |
|
---|
6728 | For data debugging there is the C<dump> command which takes the same
|
---|
6729 | arguments as make/test/install and outputs the object's Data::Dumper
|
---|
6730 | dump.
|
---|
6731 |
|
---|
6732 | =head2 Floppy, Zip, Offline Mode
|
---|
6733 |
|
---|
6734 | CPAN.pm works nicely without network too. If you maintain machines
|
---|
6735 | that are not networked at all, you should consider working with file:
|
---|
6736 | URLs. Of course, you have to collect your modules somewhere first. So
|
---|
6737 | you might use CPAN.pm to put together all you need on a networked
|
---|
6738 | machine. Then copy the $CPAN::Config->{keep_source_where} (but not
|
---|
6739 | $CPAN::Config->{build_dir}) directory on a floppy. This floppy is kind
|
---|
6740 | of a personal CPAN. CPAN.pm on the non-networked machines works nicely
|
---|
6741 | with this floppy. See also below the paragraph about CD-ROM support.
|
---|
6742 |
|
---|
6743 | =head1 CONFIGURATION
|
---|
6744 |
|
---|
6745 | When the CPAN module is used for the first time, a configuration
|
---|
6746 | dialog tries to determine a couple of site specific options. The
|
---|
6747 | result of the dialog is stored in a hash reference C< $CPAN::Config >
|
---|
6748 | in a file CPAN/Config.pm.
|
---|
6749 |
|
---|
6750 | The default values defined in the CPAN/Config.pm file can be
|
---|
6751 | overridden in a user specific file: CPAN/MyConfig.pm. Such a file is
|
---|
6752 | best placed in $HOME/.cpan/CPAN/MyConfig.pm, because $HOME/.cpan is
|
---|
6753 | added to the search path of the CPAN module before the use() or
|
---|
6754 | require() statements.
|
---|
6755 |
|
---|
6756 | The configuration dialog can be started any time later again by
|
---|
6757 | issueing the command C< o conf init > in the CPAN shell.
|
---|
6758 |
|
---|
6759 | Currently the following keys in the hash reference $CPAN::Config are
|
---|
6760 | defined:
|
---|
6761 |
|
---|
6762 | build_cache size of cache for directories to build modules
|
---|
6763 | build_dir locally accessible directory to build modules
|
---|
6764 | index_expire after this many days refetch index files
|
---|
6765 | cache_metadata use serializer to cache metadata
|
---|
6766 | cpan_home local directory reserved for this package
|
---|
6767 | dontload_hash anonymous hash: modules in the keys will not be
|
---|
6768 | loaded by the CPAN::has_inst() routine
|
---|
6769 | gzip location of external program gzip
|
---|
6770 | histfile file to maintain history between sessions
|
---|
6771 | histsize maximum number of lines to keep in histfile
|
---|
6772 | inactivity_timeout breaks interactive Makefile.PLs after this
|
---|
6773 | many seconds inactivity. Set to 0 to never break.
|
---|
6774 | inhibit_startup_message
|
---|
6775 | if true, does not print the startup message
|
---|
6776 | keep_source_where directory in which to keep the source (if we do)
|
---|
6777 | make location of external make program
|
---|
6778 | make_arg arguments that should always be passed to 'make'
|
---|
6779 | make_install_arg same as make_arg for 'make install'
|
---|
6780 | makepl_arg arguments passed to 'perl Makefile.PL'
|
---|
6781 | pager location of external program more (or any pager)
|
---|
6782 | prerequisites_policy
|
---|
6783 | what to do if you are missing module prerequisites
|
---|
6784 | ('follow' automatically, 'ask' me, or 'ignore')
|
---|
6785 | proxy_user username for accessing an authenticating proxy
|
---|
6786 | proxy_pass password for accessing an authenticating proxy
|
---|
6787 | scan_cache controls scanning of cache ('atstart' or 'never')
|
---|
6788 | tar location of external program tar
|
---|
6789 | term_is_latin if true internal UTF-8 is translated to ISO-8859-1
|
---|
6790 | (and nonsense for characters outside latin range)
|
---|
6791 | unzip location of external program unzip
|
---|
6792 | urllist arrayref to nearby CPAN sites (or equivalent locations)
|
---|
6793 | wait_list arrayref to a wait server to try (See CPAN::WAIT)
|
---|
6794 | ftp_proxy, } the three usual variables for configuring
|
---|
6795 | http_proxy, } proxy requests. Both as CPAN::Config variables
|
---|
6796 | no_proxy } and as environment variables configurable.
|
---|
6797 |
|
---|
6798 | You can set and query each of these options interactively in the cpan
|
---|
6799 | shell with the command set defined within the C<o conf> command:
|
---|
6800 |
|
---|
6801 | =over 2
|
---|
6802 |
|
---|
6803 | =item C<o conf E<lt>scalar optionE<gt>>
|
---|
6804 |
|
---|
6805 | prints the current value of the I<scalar option>
|
---|
6806 |
|
---|
6807 | =item C<o conf E<lt>scalar optionE<gt> E<lt>valueE<gt>>
|
---|
6808 |
|
---|
6809 | Sets the value of the I<scalar option> to I<value>
|
---|
6810 |
|
---|
6811 | =item C<o conf E<lt>list optionE<gt>>
|
---|
6812 |
|
---|
6813 | prints the current value of the I<list option> in MakeMaker's
|
---|
6814 | neatvalue format.
|
---|
6815 |
|
---|
6816 | =item C<o conf E<lt>list optionE<gt> [shift|pop]>
|
---|
6817 |
|
---|
6818 | shifts or pops the array in the I<list option> variable
|
---|
6819 |
|
---|
6820 | =item C<o conf E<lt>list optionE<gt> [unshift|push|splice] E<lt>listE<gt>>
|
---|
6821 |
|
---|
6822 | works like the corresponding perl commands.
|
---|
6823 |
|
---|
6824 | =back
|
---|
6825 |
|
---|
6826 | =head2 Note on urllist parameter's format
|
---|
6827 |
|
---|
6828 | urllist parameters are URLs according to RFC 1738. We do a little
|
---|
6829 | guessing if your URL is not compliant, but if you have problems with
|
---|
6830 | file URLs, please try the correct format. Either:
|
---|
6831 |
|
---|
6832 | file://localhost/whatever/ftp/pub/CPAN/
|
---|
6833 |
|
---|
6834 | or
|
---|
6835 |
|
---|
6836 | file:///home/ftp/pub/CPAN/
|
---|
6837 |
|
---|
6838 | =head2 urllist parameter has CD-ROM support
|
---|
6839 |
|
---|
6840 | The C<urllist> parameter of the configuration table contains a list of
|
---|
6841 | URLs that are to be used for downloading. If the list contains any
|
---|
6842 | C<file> URLs, CPAN always tries to get files from there first. This
|
---|
6843 | feature is disabled for index files. So the recommendation for the
|
---|
6844 | owner of a CD-ROM with CPAN contents is: include your local, possibly
|
---|
6845 | outdated CD-ROM as a C<file> URL at the end of urllist, e.g.
|
---|
6846 |
|
---|
6847 | o conf urllist push file://localhost/CDROM/CPAN
|
---|
6848 |
|
---|
6849 | CPAN.pm will then fetch the index files from one of the CPAN sites
|
---|
6850 | that come at the beginning of urllist. It will later check for each
|
---|
6851 | module if there is a local copy of the most recent version.
|
---|
6852 |
|
---|
6853 | Another peculiarity of urllist is that the site that we could
|
---|
6854 | successfully fetch the last file from automatically gets a preference
|
---|
6855 | token and is tried as the first site for the next request. So if you
|
---|
6856 | add a new site at runtime it may happen that the previously preferred
|
---|
6857 | site will be tried another time. This means that if you want to disallow
|
---|
6858 | a site for the next transfer, it must be explicitly removed from
|
---|
6859 | urllist.
|
---|
6860 |
|
---|
6861 | =head1 SECURITY
|
---|
6862 |
|
---|
6863 | There's no strong security layer in CPAN.pm. CPAN.pm helps you to
|
---|
6864 | install foreign, unmasked, unsigned code on your machine. We compare
|
---|
6865 | to a checksum that comes from the net just as the distribution file
|
---|
6866 | itself. If somebody has managed to tamper with the distribution file,
|
---|
6867 | they may have as well tampered with the CHECKSUMS file. Future
|
---|
6868 | development will go towards strong authentication.
|
---|
6869 |
|
---|
6870 | =head1 EXPORT
|
---|
6871 |
|
---|
6872 | Most functions in package CPAN are exported per default. The reason
|
---|
6873 | for this is that the primary use is intended for the cpan shell or for
|
---|
6874 | one-liners.
|
---|
6875 |
|
---|
6876 | =head1 POPULATE AN INSTALLATION WITH LOTS OF MODULES
|
---|
6877 |
|
---|
6878 | Populating a freshly installed perl with my favorite modules is pretty
|
---|
6879 | easy if you maintain a private bundle definition file. To get a useful
|
---|
6880 | blueprint of a bundle definition file, the command autobundle can be used
|
---|
6881 | on the CPAN shell command line. This command writes a bundle definition
|
---|
6882 | file for all modules that are installed for the currently running perl
|
---|
6883 | interpreter. It's recommended to run this command only once and from then
|
---|
6884 | on maintain the file manually under a private name, say
|
---|
6885 | Bundle/my_bundle.pm. With a clever bundle file you can then simply say
|
---|
6886 |
|
---|
6887 | cpan> install Bundle::my_bundle
|
---|
6888 |
|
---|
6889 | then answer a few questions and then go out for a coffee.
|
---|
6890 |
|
---|
6891 | Maintaining a bundle definition file means keeping track of two
|
---|
6892 | things: dependencies and interactivity. CPAN.pm sometimes fails on
|
---|
6893 | calculating dependencies because not all modules define all MakeMaker
|
---|
6894 | attributes correctly, so a bundle definition file should specify
|
---|
6895 | prerequisites as early as possible. On the other hand, it's a bit
|
---|
6896 | annoying that many distributions need some interactive configuring. So
|
---|
6897 | what I try to accomplish in my private bundle file is to have the
|
---|
6898 | packages that need to be configured early in the file and the gentle
|
---|
6899 | ones later, so I can go out after a few minutes and leave CPAN.pm
|
---|
6900 | untended.
|
---|

---|
6902 | =head1 WORKING WITH CPAN.pm BEHIND FIREWALLS
|
---|
6903 |
|
---|
6904 | Thanks to Graham Barr for contributing the following paragraphs about
|
---|
6905 | the interaction between perl, and various firewall configurations. For
|
---|
6906 | further informations on firewalls, it is recommended to consult the
|
---|
6907 | documentation that comes with the ncftp program. If you are unable to
|
---|
6908 | go through the firewall with a simple Perl setup, it is very likely
|
---|
6909 | that you can configure ncftp so that it works for your firewall.
|
---|
6910 |
|
---|
6911 | =head2 Three basic types of firewalls
|
---|
6912 |
|
---|
6913 | Firewalls can be categorized into three basic types.
|
---|
6914 |
|
---|
6915 | =over 4
|
---|
6916 |
|
---|
6917 | =item http firewall
|
---|
6918 |
|
---|
6919 | This is where the firewall machine runs a web server and to access the
|
---|
6920 | outside world you must do it via the web server. If you set environment
|
---|
6921 | variables like http_proxy or ftp_proxy to a values beginning with http://
|
---|
6922 | or in your web browser you have to set proxy information then you know
|
---|
6923 | you are running an http firewall.
|
---|
6924 |
|
---|
6925 | To access servers outside these types of firewalls with perl (even for
|
---|
6926 | ftp) you will need to use LWP.
|
---|
6927 |
|
---|
6928 | =item ftp firewall
|
---|
6929 |
|
---|
6930 | This where the firewall machine runs an ftp server. This kind of
|
---|
6931 | firewall will only let you access ftp servers outside the firewall.
|
---|
6932 | This is usually done by connecting to the firewall with ftp, then
|
---|
6933 | entering a username like "[email protected]"
|
---|
6934 |
|
---|
6935 | To access servers outside these type of firewalls with perl you
|
---|
6936 | will need to use Net::FTP.
|
---|
6937 |
|
---|
6938 | =item One way visibility
|
---|
6939 |
|
---|
6940 | I say one way visibility as these firewalls try to make themselves look
|
---|
6941 | invisible to the users inside the firewall. An FTP data connection is
|
---|
6942 | normally created by sending the remote server your IP address and then
|
---|
6943 | listening for the connection. But the remote server will not be able to
|
---|
6944 | connect to you because of the firewall. So for these types of firewall
|
---|
6945 | FTP connections need to be done in a passive mode.
|
---|
6946 |
|
---|
6947 | There are two that I can think off.
|
---|
6948 |
|
---|
6949 | =over 4
|
---|
6950 |
|
---|
6951 | =item SOCKS
|
---|
6952 |
|
---|
6953 | If you are using a SOCKS firewall you will need to compile perl and link
|
---|
6954 | it with the SOCKS library, this is what is normally called a 'socksified'
|
---|
6955 | perl. With this executable you will be able to connect to servers outside
|
---|
6956 | the firewall as if it is not there.
|
---|
6957 |
|
---|
6958 | =item IP Masquerade
|
---|
6959 |
|
---|
6960 | This is the firewall implemented in the Linux kernel, it allows you to
|
---|
6961 | hide a complete network behind one IP address. With this firewall no
|
---|
6962 | special compiling is needed as you can access hosts directly.
|
---|
6963 |
|
---|
6964 | For accessing ftp servers behind such firewalls you may need to set
|
---|
6965 | the environment variable C<FTP_PASSIVE> to a true value, e.g.
|
---|
6966 |
|
---|
6967 | env FTP_PASSIVE=1 perl -MCPAN -eshell
|
---|
6968 |
|
---|
6969 | or
|
---|
6970 |
|
---|
6971 | perl -MCPAN -e '$ENV{FTP_PASSIVE} = 1; shell'

6978 | =head2 Configuring lynx or ncftp for going through a firewall
|
---|
6979 |
|
---|
6980 | If you can go through your firewall with e.g. lynx, presumably with a
|
---|
6981 | command such as
|
---|
6982 |
|
---|
6983 | /usr/local/bin/lynx -pscott:tiger
|
---|
6984 |
|
---|
6985 | then you would configure CPAN.pm with the command
|
---|
6986 |
|
---|
6987 | o conf lynx "/usr/local/bin/lynx -pscott:tiger"
|
---|
6988 |
|
---|
6989 | That's all. Similarly for ncftp or ftp, you would configure something
|
---|
6990 | like
|
---|
6991 |
|
---|
6992 | o conf ncftp "/usr/bin/ncftp -f /home/scott/ncftplogin.cfg"
|
---|
6993 |
|
---|
6994 | Your mileage may vary...

7000 | =item 1)
|
---|
7001 |
|
---|
7002 | I installed a new version of module X but CPAN keeps saying,
|
---|
7003 | I have the old version installed
|
---|
7004 |
|
---|
7005 | Most probably you B<do> have the old version installed. This can
|
---|
7006 | happen if a module installs itself into a different directory in the
|
---|
7007 | @INC path than it was previously installed. This is not really a
|
---|
7008 | CPAN.pm problem, you would have the same problem when installing the
|
---|
7009 | module manually. The easiest way to prevent this behaviour is to add
|
---|
7010 | the argument C<UNINST=1> to the C<make install> call, and that is why
|
---|
7011 | many people add this argument permanently by configuring
|
---|
7012 |
|
---|
7013 | o conf make_install_arg UNINST=1
|
---|
7014 |
|
---|
7015 | =item 2)
|
---|
7016 |
|
---|
7017 | So why is UNINST=1 not the default?
|
---|
7018 |
|
---|
7019 | Because there are people who have their precise expectations about who
|
---|
7020 | may install where in the @INC path and who uses which @INC array. In
|
---|
7021 | fine tuned environments C<UNINST=1> can cause damage.

7025 | I want to clean up my mess, and install a new perl along with
|
---|
7026 | all modules I have. How do I go about it?
|
---|
7027 |
|
---|
7028 | Run the autobundle command for your old perl and optionally rename the
|
---|
7029 | resulting bundle file (e.g. Bundle/mybundle.pm), install the new perl
|
---|
7030 | with the Configure option prefix, e.g.
|
---|
7031 |
|
---|
7032 | ./Configure -Dprefix=/usr/local/perl-5.6.78.9
|
---|
7033 |
|
---|
7034 | Install the bundle file you produced in the first step with something like
|
---|
7035 |
|
---|
7036 | cpan> install Bundle::mybundle
|
---|
7037 |
|
---|
7038 | and you're done.

7041 |
|
---|
7042 | When I install bundles or multiple modules with one command
|
---|
7043 | there is too much output to keep track of.
|
---|
7044 |
|
---|
7045 | You may want to configure something like
|
---|
7046 |
|
---|
7047 | o conf make_arg "| tee -ai /root/.cpan/logs/make.out"
|
---|
7048 | o conf make_install_arg "| tee -ai /root/.cpan/logs/make_install.out"
|
---|
7049 |
|
---|
7050 | so that STDOUT is captured in a file for later inspection.

7055 | I am not root, how can I install a module in a personal directory?
|
---|
7056 |
|
---|
7057 | You will most probably like something like this:
|
---|
7058 |
|
---|
7059 | o conf makepl_arg "LIB=~/myperl/lib \
|
---|
7060 | INSTALLMAN1DIR=~/myperl/man/man1 \
|
---|
7061 | INSTALLMAN3DIR=~/myperl/man/man3"
|
---|
7062 | install Sybase::Sybperl
|
---|
7063 |
|
---|
7064 | You can make this setting permanent like all C<o conf> settings with
|
---|
7065 | C<o conf commit>.
|
---|
7066 |
|
---|
7067 | You will have to add ~/myperl/man to the MANPATH environment variable
|
---|
7068 | and also tell your perl programs to look into ~/myperl/lib, e.g. by
|
---|
7069 | including
|
---|
7070 |
|
---|
7071 | use lib "$ENV{HOME}/myperl/lib";
|
---|
7072 |
|
---|
7073 | or setting the PERL5LIB environment variable.
|
---|
7074 |
|
---|
7075 | Another thing you should bear in mind is that the UNINST parameter
|
---|
7076 | should never be set if you are not root.

7080 | How to get a package, unwrap it, and make a change before building it?

7086 | I installed a Bundle and had a couple of fails. When I
|
---|
7087 | retried, everything resolved nicely. Can this be fixed to work
|
---|
7088 | on first try?
|
---|
7089 |
|
---|
7090 | The reason for this is that CPAN does not know the dependencies of all
|
---|
7091 | modules when it starts out. To decide about the additional items to
|
---|
7092 | install, it just uses data found in the generated Makefile. An
|
---|
7093 | undetected missing piece breaks the process. But it may well be that
|
---|
7094 | your Bundle installs some prerequisite later than some depending item
|
---|
7095 | and thus your second try is able to resolve everything. Please note,
|
---|
7096 | CPAN.pm does not know the dependency tree in advance and cannot sort
|
---|
7097 | the queue of things to install in a topologically correct order. It
|
---|
7098 | resolves perfectly well IFF all modules declare the prerequisites
|
---|
7099 | correctly with the PREREQ_PM attribute to MakeMaker. For bundles which
|
---|
7100 | fail and you need to install often, it is recommended sort the Bundle
|
---|
7101 | definition file manually. It is planned to improve the metadata
|
---|
7102 | situation for dependencies on CPAN in general, but this will still
|
---|
7103 | take some time.

7107 | In our intranet we have many modules for internal use. How
|
---|
7108 | can I integrate these modules with CPAN.pm but without uploading
|
---|
7109 | the modules to CPAN?
|
---|
7110 |
|
---|
7111 | Have a look at the CPAN::Site module.

|
---|
7116 | setting meta input/output via the /etc/inputrc file.
|
---|
7117 |
|
---|
7118 | Some versions of readline are picky about capitalization in the
|
---|
7119 | /etc/inputrc file and specifically RedHat 6.2 comes with a
|
---|
7120 | /etc/inputrc that contains the word C<on> in lowercase. Change the
|
---|
7121 | occurrences of C<on> to C<On> and the bug should disappear.

7125 | Some authors have strange characters in their names.
|
---|
7126 |
|
---|
7127 | Internally CPAN.pm uses the UTF-8 charset. If your terminal is
|
---|
7128 | expecting ISO-8859-1 charset, a converter can be activated by setting
|
---|
7129 | term_is_latin to a true value in your config file. One way of doing so
|
---|
7130 | would be
|
---|
7131 |
|
---|
7132 | cpan> ! $CPAN::Config->{term_is_latin}=1
|
---|
7133 |
|
---|
7134 | Extended support for converters will be made available as soon as perl
|
---|
7135 | becomes stable with regard to charset issues.

7139 | =head1 BUGS
|
---|
7140 |
|
---|
7141 | We should give coverage for B<all> of the CPAN and not just the PAUSE
|
---|
7142 | part, right? In this discussion CPAN and PAUSE have become equal --
|
---|
7143 | but they are not. PAUSE is authors/, modules/ and scripts/. CPAN is
|
---|
7144 | PAUSE plus the clpa/, doc/, misc/, ports/, and src/.
|
---|
7145 |
|
---|
7146 | Future development should be directed towards a better integration of
|
---|
7147 | the other parts.
|
---|
7148 |
|
---|
7149 | If a Makefile.PL requires special customization of libraries, prompts
|
---|
7150 | the user for special input, etc. then you may find CPAN is not able to
|
---|
7151 | build the distribution. In that case, you should attempt the
|
---|
7152 | traditional method of building a Perl module package from a shell.
