NAME

CPAN::Reporter::Smoker::Safer - Turnkey smoking of installed distros

VERSION

Version 0.03

SYNOPSIS

# Default usage
perl -MCPAN::Reporter::Smoker::Safer -e start

# Control the 'trust' params for the default filter
perl -MCPAN::Reporter::Smoker::Safer -e 'start( safer=>{min_reports=>0, min_days_old=>2} )'

# Smoke all installed modules from a specific namespace
perl -MCPAN::Reporter::Smoker::Safer -e 'start( safer=>{min_reports=>0, min_days_old=>0, mask=>"/MyFoo::/"} )'

# Custom filter (in this case, specific authorid)
perl -MCPAN::Reporter::Smoker::Safer -e 'start( safer=>{filter=>sub{$_[1]->pretty_id =~ m#/DAVIDRW/#}} )'

# Preview mode - display distros found
perl -MCPAN::Reporter::Smoker::Safer -MData::Dumper -e 'print Dumper start(safer=>{preview=>1})'

DESCRIPTION

This is a subclass of CPAN::Reporter::Smoker that will limit the set of tested distributions to ones that are "trusted". This means that the distribution is already installed on the system, and that the new version it has been on CPAN for a certain amount of time, and has already received a certain number of test reporters. The assumption is that is it is safe (as in "safer") to install distributions (and their dependencies) that meet that criteria.

This can be used to run partial smoke testing on a box that normally wouldn't be desired for full smoke testing (i.e. isn't a dedicated/isolated environment). Another potential use is to vet everything before upgrading.

GETTING STARTED

Start with installing and configuring CPAN::Reporter -- after that you should be all set. There are also some very good hints and notes in the CPAN::Reporter::Smoker documentation.

WARNING -- smoke testing is risky

While in theory this is much safer than full CPAN smoke testing, ALL of the same risks (see CPAN::Reporter::Smoker) still apply:

Smoke testing will download and run programs that other people have uploaded to CPAN. These programs could do *anything* to your system, including deleting everything on it. Do not run CPAN::Reporter::Smoker unless you are prepared to take these risks.

USAGE

start()

This is an overload of CPAN::Reporter::Smoker::start, and supports the same arguments, with the exception of list which is set internally. In addition, supports the following argument:

safer

Hashref with the following possible keys:

mask

Scalar; Defaults to '/./'; Value is passed to CPAN::Shell::expand() for filtering the module list (applies to module names, not distro names).

filter

Code ref; Defaults to "__filter". First argument is the CPAN::Reporter::Smoker::Safer class/object; Second argument is a CPAN::Distribution object. Return value should be 1 (true) to accept, and 0 (false) to reject the distribution.

	filter => sub {
	  my ($safer, $dist) = @_;
	  ...
          return 1; 
	},
min_reports

Defaults to 10. This is used by the default filter -- distros are 'trusted' if they have at least this many CPAN testers reports already.

min_days_old

Defaults to 10. This is used by the default filter -- distros are 'trusted' unless they were uploaded to CPAN at least this many days ago.

exclusions

Defaults to [ qr#/perl-5\.#, qr#/mod_perl-\d# ]. This is used by the default filter to exclude any distro whose name (e.g. A/AU/AUTHOR/Foo-Bar-1.23.tar.gz) matches one of these regexes.

Note that the disabled.yml functionality might be more suitable. See CPAN::Reporter::Smoker, CPAN, and CPAN::Distroprefs for more details.

preview

Default false. If true, instead of invoking CPAN::Reporter::Smoker::start() will just return the args (as hashref) that would have been passsed to start(). This is usefull for debugging/testing without kicking off the actual smoke tester.

INTERNAL METHODS

__filter

Used as the default "filter" code ref.

  • Excludes any distro who's name (e.g. A/AU/AUTHOR/Foo-Bar-1.23.tar.gz) matches a list of "exclusions".

  • Exclude any distro that was uploaded to CPAN less than "min_days_old" days ago.

  • Exclude any distro that has less than "min_reports" CPAN Testers reports.

__installed_dists

Returns an array ref of dist names (e.g. 'ANDK/CPAN-1.9301.tar.gz' ).

CPAN::Reporter::Smoker::Safer->__installed_dists( $mask, $filter );

mask is optional, and is same value as "mask". filter is optional, and is same value as "filter".
