CPANPLUS::YACSmoke - Yet Another CPANPLUS Smoke Tester


version 1.08


  perl -MCPANPLUS::YACSmoke -e test


CPANPLUS::YACSmoke is an enhancement of the venerable CPAN::YACSmoke that uses the API backend of CPANPLUS to run tests on CPAN modules and post results to the CPAN Testers list.

CPANPLUS::Dist::YACSmoke is loaded into the CPANPLUS configuration before any modules are tested.

It will create a database file in the .cpanplus directory, which it uses to track tested distributions. This information will be used to keep from posting multiple reports for the same module, and to keep from testing modules that use non-passing modules as prerequisites.

If prereqs have been tested previously and have resulted in a pass grade then the tests for those prereqs will be skipped, speeding up smoke testing.

By default it uses CPANPLUS configuration settings.


CPANPLUS::YACSmoke only honours the exclude_dists in CPAN::YACSmoke style ini files.

The exclude_dists setting, which is laid out as:


The above would then ignore any distribution that includes the string 'mod_perl' in its name. This is useful for distributions which use external C libraries, which are not installed, or for which testing is problematic.

CPANPLUS::YACSmoke also supports exclude_auths in the ini file. Similar to exclude_dists, but for excluding all distributions by a particular CPAN author ID.


The above would ignore all distributions of any CPAN author ID that begins with ASS, such as ASSAM and ASSONIA.

Experimental support for local::lib type environment has been added. In the ini file specify the local::lib setting to enable this feature.

  local::lib = 1

Setting this will make CPANPLUS::YACSmoke setup a local::lib under the current working directory before testing starts. All modules tested (and prereqs resolved during testing) will be installed into the local::lib. When testing finishes, the local::lib will be removed.

See Config::IniFiles for more information on the INI file format.



The following routines are exported by default. They are intended to be called from the command-line, though they could be used from a script.

test( [ $dist [, $dist .... ] ] )
  perl -MCPANPLUS::YACSmoke -e test

  perl -MCPANPLUS::YACSmoke -e test('R/RR/RRWO/Some-Dist-0.01.tar.gz')

Runs tests on CPAN distributions. Arguments should be paths of individual distributions in the author directories. If no arguments are given, it will download the RECENT file from CPAN and use that.

By default it uses CPANPLUS configuration settings. If CPANPLUS is set not to send test reports, then it will not send test reports.

mark( $dist [, $grade ] ] )
  perl -MCPANPLUS::YACSmoke -e mark('Some-Dist-0.01')

  perl -MCPANPLUS::YACSmoke -e mark('Some-Dist-0.01', 'fail')

Retrieves the test result in the database, or changes the test result.

It can be useful to update the status of a distribution that once failed or was untestable but now works, so as to test modules which make use of it.

Grades can be one of (case insensitive):

  aborted  = tests aborted (uninstallable prereqs or other failure in test)
  pass     = passed tests
  fail     = failed tests
  unknown  = no tests available
  na       = not applicable to platform or installed libraries
  ungraded = no grade (test possibly aborted by user)
  none     = undefines a grade
  ignored  = package was ignored (a newer version was tested)
excluded( [ $dist [, $dist ... ] ] )
  perl -MCPANPLUS::YACSmoke -e excluded('Some-Dist-0.01')

  perl -MCPANPLUS::YACSmoke -e excluded()

Given a list of distributions, indicates which ones would be excluded from testing, based on the exclude_dist list that is created.

purge( [ \%config, ] [ $dist [, $dist ... ] ] )
  perl -MCPANPLUS::YACSmoke -e purge()

  perl -MCPANPLUS::YACSmoke -e purge('Some-Dist-0.01')

Purges the entries from the local cpansmoke database. The criteria for purging is that a distribution must have a more recent version, which has previously been marked as a PASS. However, if one or more distributions are passed as a parameter list, those specific distributions will be purged.

If the flush_flag is set, via the config hashref, to a true value, the directory path created for each older copy of a distribution is deleted.

flush( [ 'all' | 'old' ] )
  perl -MCPANPLUS::YACSmoke -e flush()

  perl -MCPANPLUS::YACSmoke -e flush('all')

  perl -MCPANPLUS::YACSmoke -e flush('old')

Removes unrequired build directories from the designated CPANPLUS build directory. Note that this deletes directories regardless of whether the associated distribution was tested.

Default flush is 'all'. The 'old' option will only delete the older distributions, of multiple instances of a distribution.

Note that this cannot be done reliably using last access or modify time, as the intention is for this distribution to be used on any OS that CPANPLUS is installed on. In this case not all OSs support the full range of return values from the stat function.


Make CPANPLUS reload its indices.


Each of the procedural interface functions are available as methods of a CPANPLUS::YACSmoke object.


The object interface is created normally through the test() or mark() functions of the procedural interface.


The following environment variables affect the operation of this module:


Loaded into CPANPLUS by CPANPLUS::Config::YACSmoke, sets the basedir where CPANPLUS and CPANPLUS::YACSmoke related modules find the .cpanplus directory for their settings

  export PERL5_YACSMOKE_BASE=/home/moo/perls/conf/perl-5.8.9/

Would set the base dir to /home/moo/perls/conf/perl-5.8.9/.cpanplus/

Several environment variables get set by the module:


Set to 1 to indicate that we are currently running in an automated testing environment


Set to 1 MakeMaker and Module::Build's prompt functions will always return the default without waiting for user input.


Test::Reporter uses this. YACSmoke will set this if it isn't already set. It will try to determine the domain from the email setting in CPANPLUS. If this is it will default to ( the MX doesn't like people trying to impersonate it, for obvious reasons ).
