=head1 NAME

CPANPLUS::Internals::Report

=head1 SYNOPSIS

  ### enable test reporting
  $cb->configure_object->set_conf( cpantest => 1 );
    
  ### set custom mx host, shouldn't normally be needed
  $cb->configure_object->set_conf( cpantest_mx => 'smtp.example.com' );

=head1 DESCRIPTION

This module provides all the functionality to send test reports to
C<http://testers.cpan.org> using the C<Test::Reporter> module.

All methods will be called automatically if you have C<CPANPLUS>
configured to enable test reporting (see the C<SYNOPSIS>).

=head1 METHODS

=head2 $bool = $cb->_have_query_report_modules

This function checks if all the required modules are here for querying
reports. It returns true and loads them if they are, or returns false
otherwise.

=head2 $bool = $cb->_have_send_report_modules

This function checks if all the required modules are here for sending
reports. It returns true and loads them if they are, or returns false
otherwise.

=head2 @list = $cb->_query_report( module => $modobj, [all_versions => BOOL, verbose => BOOL] )

This function queries the CPAN testers database at
I<http://testers.cpan.org/> for test results of specified module objects,
module names or distributions.

The optional argument C<all_versions> controls whether all versions of
a given distribution should be grabbed.  It defaults to false
(fetching only reports for the current version).

Returns the a list with the following data structures (for CPANPLUS
version 0.042) on success, or false on failure:

          {
            'grade' => 'PASS',
            'dist' => 'CPANPLUS-0.042',
            'platform' => 'i686-pld-linux-thread-multi'
          },
          {
            'grade' => 'PASS',
            'dist' => 'CPANPLUS-0.042',
            'platform' => 'i686-linux-thread-multi'
          },
          {
            'grade' => 'FAIL',
            'dist' => 'CPANPLUS-0.042',
            'platform' => 'cygwin-multi-64int',
            'details' => 'http://nntp.x.perl.org/group/perl.cpan.testers/99371'

            'details' => 'http://nntp.x.perl.org/group/perl.cpan.testers/99396'
          },

The status of the test can be one of the following:
UNKNOWN, PASS, FAIL or NA (not applicable).

=head2 $bool = $cb->_send_report( module => $modobj, buffer => $make_output, failed => BOOL, [save => BOOL, address => $email_to, dontcc => BOOL, verbose => BOOL, force => BOOL]);

This function sends a testers report to C<[e-mail]> for a
particular distribution.
It returns true on success, and false on failure.

It takes the following options:

=over 4

=item module

The module object of this particular distribution

=item buffer

The output buffer from the 'make/make test' process

=item failed

Boolean indicating if the 'make/make test' went wrong

=item save

Boolean indicating if the report should be saved locally instead of
mailed out. If provided, this function will return the location the
report was saved to, rather than a simple boolean 'TRUE'.

Defaults to false.

=item address

The email address to mail the report for. You should never need to
override this, but it might be useful for debugging purposes.

Defaults to C<[e-mail]>.

=item dontcc

Boolean indicating whether or not we should Cc: the author. If false,
previous error reports are inspected and checked if the author should
be mailed. If set to true, these tests are skipped and the author is
definitely not Cc:'d.
You should probably not change this setting.

Defaults to false.

=item verbose

Boolean indicating on whether or not to be verbose.

Defaults to your configuration settings

=item force

Boolean indicating whether to force the sending, even if the max
amount of reports for fails have already been reached, or if you
may already have sent it before.

Defaults to your configuration settings
