=head1 TASKS
=head2 deploy
rex deploy
rex -E vm deploy
Deploy the CPAN Testers schema from CPAN and upgrade the database schema
if necessary. Do this task after releasing a version of
CPAN::Testers::Schema to CPAN.
=cut
desc "Deploy the CPAN Testers Schema from CPAN";
task deploy =>
group => 'all',
sub {
run 'source ~/.profile; cpanm CPAN::Testers::Schema DBD::mysql';
run_task 'upgrade_database', on => connection->server;
};
=head2 deploy_dev
rex -E vm deploy_dev
Deploy a pre-release, development version of the schema. Use this to
install to your dev VM to test things. Will run `dzil build` locally
to build the tarball, then sync that tarball to the remote and install
using `cpanm`.
=cut
task deploy_dev =>
group => 'all',
sub {
my $dist_name = get 'dist_name';
my $dist;
LOCAL {
Rex::Logger::info( 'Building dist' );
run 'dzil build';
my @dists = sort glob "${dist_name}-*.tar.gz";
$dist = $dists[-1];
};
Rex::Logger::info( 'Syncing ' . $dist );
file '~/dist/' . $dist,
source => $dist;
Rex::Logger::info( 'Installing ' . $dist );
run 'source ~/.profile; cpanm --notest ~/dist/' . $dist . ' DBD::mysql';
run_task 'upgrade_database', on => connection->server;
};
=head2 upgrade_database
Upgrade the database running on the given server. This task is called
automatically by C<deploy> and C<deploy_dev>.
This task also restarts all running services, since the code version and
the database version must match.
=cut
task upgrade_database =>
group => 'all',
sub {
Rex::Logger::info( 'Upgrading database' );
run 'source ~/.profile; cpantesters-schema upgrade';
if ( $? ) {
say last_command_output;
}
run_task 'restart', on => connection->server;
};
=head2 install_database
Install the database on the server. This task should be called once to
initialize the database. It can be safely run on an already-existing
database.
=cut
task install_database =>
group => 'all',
sub {
Rex::Logger::info( 'Installing database' );
run 'mysql --defaults-file=~/.cpanstats.cnf --database "" -e"create database cpanstats"';
run 'source ~/.profile; cpantesters-schema install';
if ( $? ) {
say last_command_output;
}
};
=head2 restart
Restart all the services on the machine. This is run automatically by
the deploy processes after upgrading the database.
The code version and the database version must be in-sync, and any
running processes must get the new code by restarting.
=cut
task restart =>
group => 'all',
sub {
Rex::Logger::info( 'Restating all services' );
run 'sv restart ~/service/*';
if ( $? ) {
say last_command_output;
}
};

=head1 SUBROUTINES
=head2 ensure_sudo_password
Ensure a C<sudo> password is set. Use this at the start of any task
that requires C<sudo>.
=cut

return if sudo_password();
return if get 'no_sudo_password';
print 'Password to use for sudo: ';
ReadMode('noecho');
