DESCRIPTION ^

minismokebox is a lightweight version of SmokeBox that performs CPAN testing on a single perl installation.

It is usually installed into a separate perl installation than the perl which is being tested, the system perl for instance.

   /usr/bin/minismokebox --perl /home/cpan/sandbox/perl-5.10.0/bin/perl

The above command will run minismokebox which will obtain a list of recently uploaded distributions to CPAN and then proceed to smoke each of these distributions against the indicated perl.

minismokebox supports a number of different CPAN Tester frameworks ( in POE::Component::SmokeBox parlance a backend ), currently, CPANPLUS::YACSmoke, CPAN::Reporter and CPAN::YACSmoke.

   /usr/bin/minismokebox --perl /home/cpan/sandbox/perl-5.10.0/bin/perl # uses default 'CPANPLUS::YACSmoke'

   /usr/bin/minismokebox --perl /home/cpan/sandbox/perl-5.10.0/bin/perl --backend CPAN::Reporter

   /usr/bin/minismokebox --perl /home/cpan/sandbox/perl-5.10.0/bin/perl --backend CPAN::YACSmoke

minismokebox will check that the selected backend exists in the indicated perl before proceeding with the smoke phase. This is very simple check and does not test whether the smoke environment is properly configured to send test reports, etc. Consult the applicable documentation for instructions on how to configure the testing environment. ( See the links below in "SEE ALSO" ).

WARNING ^

There are risks associated with CPAN smoke testing. You are effectively downloading and executing arbitary code on your system.

Here are some tips to mitigate the risks:

Use a sandbox account

Don't run smoke tests as root or other priviledged user. Create a separate user account to smoke test under. For the even more paranoid you can give the HOME directory for this user account a separate filesystem.

Use a virtualised system

Virtualise your testing environment with Xen, Vmware, VirtualBox, etc. If the system does get hosed you can recover it from a snapshot backup very quickly.

Chown the perl installation to root

Making sure that the user who is running the smoke testing can't write to the perl installation is a very good plan. There have been incidents in the past where a recalcitrant module has managed to trash smoke test environments.

Monitor your TEMP file area

Keep an eye on the /tmp directory, a lot of test-suites leave droppings behind.

COMMAND LINE OPTIONS ^

Command line options override options given in the "CONFIGURATION FILE"

--debug

Turns on all output from the POE::Component::SmokeBox::Backend as distributions are smoked.

--help

Displays program usage and exits.

--version

Displays the program version and exits.

--perl PERL

The path to a perl executable to run the smoke testing against. If this isn't specified minismokebox will use $^X to determine the current perl and use that.

--backend BACKEND

Specify a particular POE::Component::SmokeBox::Backend to use for smoking. This can be CPANPLUS::YACSmoke, CPAN::YACSmoke or CPAN::Reporter. The default if this isn't specified is CPANPLUS::YACSmoke.

--indices

Indicates that minismokebox should reindex the particular backend before proceeding with the smoke testing.

--url URI

The URI of a CPAN Mirror that minismokebox will use to obtain the recent uploads from or perform package, author and phalanx searches against. For consistency this should really match the CPAN Mirror configured in the applicable backend you are using.

--home DIR

The path to a directory that will become the HOME environment variable in spawned smoke processes. It will be created if it does not exist.

--nolog

If enabled the STDOUT and STDERR of job output will not be logged.

The following options control where minismokebox obtains a list of distributions to smoke. If none of these are specified the default behaviour is --recent. These options are cumulative. For example:

  minismokebox --perl /home/cpan/perl-5.10.0/bin/perl --recent --package '^POE' --author '^BI' --phalanx

This would smoke a list of recent uploads, all distributions that begin with POE, the distributions for each CPAN author whose CPAN ID begins with BI and a list of the Phalanx 100 distributions.

--recent

Explicitly tell minismokebox to smoke the recent uploads to CPAN. This is the default action if none of the following actions are given.

--rss

Enabling this option will tell minismokebox to use the modules/01modules.mtime.rss file instead of the default RECENT file to discover recent CPAN uploads.

--noepoch

Enabling this option will disable the use of RECENT-1x.yaml files to determine the very most recent uploads to smoke.

--perlenv

Normally minismokebox ( via POE::Component::SmokeBox::Backend ) will sanctify the smoker process' environment variables to remove various perl related variables. Enabling this option will pass PERL5LIB environment variable to the smoker process if it is defined. This could have weird side-effects, use with caution.

--reverse

If specified minismokebox will smoke recent uploads in reverse order.

--jobs FILE

Indicate a file where minismokebox should get a list of distributions to smoke from, eg.

  C/CH/CHROMATIC/Acme-Incorporated-1.00.tar.gz
  B/BI/BINGOS/POE-Component-IRC-5.12.tar.gz
--package PATTERN

Specify a string representing a package search to find distributions to smoke. The pattern is a regular expression and is applied to the package or distribution name plus version number ( the so called distvname, see CPAN::DistnameInfo ), eg.

  --package '^POE'  # find all distributions that begin with POE
  --package 'IRC'   # find all IRC related distributions
  --package '0.01'  # find all distributions that are version 0.01
  --package '_\d+$' # find all development releases
--author PATTERN

Specify a string representing an author search to find distributions to smoke. The pattern is a regular expression and is applied to the CPAN ID of CPAN authors. eg.

  --author '^BINGOS$' # find all distributions that belong to BINGOS
  --author '^BI'      # find all distributions that belong to authors beginning with BI
  --author '^B'       # find all distributions for the 'B' authors
--phalanx

Specify that you want to smoke the Phalanx '100' distributions, http://qa.perl.org/phalanx.

--random

Specify that you want to smoke a random selection of 100 distributions from the CPAN indexes.

CONFIGURATION FILE ^

A number of the above options may be specified in a configuration file, minismokebox, that is stored in the .smokebox directory. See "ENVIRONMENT" for where the .smokebox directory is located and how to effect its location.

Command line options will override options from the configuration file.

The configuration file is parsed using Config::Tiny.

A subset of the command line options can be specified in the configuration file:

debug

Set to a true value to turn on all output from the POE::Component::SmokeBox::Backend as distributions are smoked.

  debug=1
indices

Set to a true value to indicate that minismokebox should reindex the particular backend before proceeding with the smoke testing.

  indices=1
recent

Set to a true value to explicitly tell minismokebox to smoke recent uploads to CPAN.

  recent=1
random

Set to a true value to specify that you want to smoke a random selection of 100 distributions from the CPAN indexes.

  random=1
rss

Enabling this option will tell minismokebox to use the modules/01modules.mtime.rss file instead of the default RECENT file to discover recent CPAN uploads.

  rss=1
noepoch

Enabling this option will disable the use of RECENT-1x.yaml files to determine the very most recent uploads to smoke.

  noepoch=1
perlenv

Normally minismokebox ( via POE::Component::SmokeBox::Backend ) will sanctify the smoker process' environment variables to remove various perl related variables. Enabling this option will pass PERL5LIB environment variable to the smoker process if it is defined. This could have weird side-effects, use with caution.

  perlenv=1
perl

Specify the path to the perl executable to use for smoke testing.

  perl=/home/cpan/rel/perl-5.10.0/bin/perl
backend

Specify the POE::Component::SmokeBox::Backend to use for smoke testing

  backend=CPAN::Reporter
url

The URI of a CPAN Mirror that minismokebox will use to obtain the recent uploads from or perform package, author and phalanx searches against. For consistency this should really match the CPAN Mirror configured in the applicable backend you are using.

  url=http://www.cpan.org/
home

The path to a directory that will become the HOME environment variable in spawned smoke processes. It will be created if it does not exist.

ENVIRONMENT

This is section within the configuration file. Any key/values specified will be passed as environment variables to the process that is created by POE::Component::SmokeBox::Backend.

  [ENVIRONMENT]
  PERL5LIB=/some/random/directory/path:/oh/and/another

ENVIRONMENT ^

minismokebox uses the .smokebox directory to locate the configuration file, minismokebox.

This is usually located in the current user's home directory. Setting the environment variable PERL5_SMOKEBOX_DIR will effect where the .smokebox directory is located.

POE::Component::SmokeBox::Backend will santify the environment of the smoker process of various variables using Env::Sanctify:

      '^POE_',
      '^PERL5_SMOKEBOX',
      '^HARNESS_',
      '^(PERL5LIB|TAP_VERSION|TEST_VERBOSE)$',
      '^AUTHOR_TESTING$',
      '^PERL_TEST',

See "CONFIGURATION FILE" for a way of propogating environment variables to the smoker process.

This behaviour can also be overriden for the PERL5LIB variable only by using the --perlenv or perlenv configuration file option. See above for details.
