=head1 NAME
IO::Iron - Client Libraries to Iron services IronCache, IronMQ and IronWorker.
=head1 VERSION
version 0.09
=cut
our $VERSION = '0.09'; # VERSION: generated by DZP::OurPkgVersion
=head1 STATUS
Iron.io libraries are currently being developed so changes in the API are
possible.
=head1 SYNOPSIS
use IO::Iron;
use IO::Iron qw{ironcache ironmq ironworker};
use IO::Iron ':all';
my $iron_mq_client = ironmq();
my @iron_mq_queues = $iron_mq_client->get_queues();
my $iron_cache_client = ironcache( config => 'iron_cache.json' );
my @iron_caches = $iron_cache_client->get_caches();
my $iron_worker_client = ironworker( config => 'iron_worker.json' );
my @iron_codes = $iron_worker_client->list_code_packages();
=head1 REQUIREMENTS
The IO::Iron::* packages require the following packages (in addition to several Perl core packages):
=over 8
=item Carp::Assert, v. 0.20
=item Carp::Assert::More, v. 1.12
=item Data::UUID', v. 1.219,
=item Exception::Class, v. 1.37
=item File::HomeDir, v. 1.00,
=item File::Slurp, v. 9999.19
=item JSON, v. 2.53
=item Log::Any, v. 0.15
=item MIME::Base64', v. 3.13
=item REST::Client, v. 88
=item Try::Tiny, v. 0.18
=item URI::Escape, v. 3.31
=item Params::Validate, v. 1.08
=back
IO::Iron also requires an IronIO account. Three configuration items must
be set (others available) before using the functions:
C<project_id>, C<token> and C<host>. These can be set in a json file,
as environmental variables or as parameters when creating the object.
=over 8
=item C<project_id>, the identification string, from IronIO.
=item C<token>, an OAuth authentication token string, from IronIO.
=item C<host>, the cloud in which you want to operate, e.g. 'cache-aws-us-east-1' for AWS (Amazon).

=head1 DESCRIPTION
IronCache, IronMQ and IronWorker are cloud based services accessible
via a REST API. CPAN Distribution IO::Iron contains Perl clients for
accessing them.
[See L<http://www.iron.io/|http://www.iron.io/>]
Please see the individual clients for further documentation and usage.
Clients:
=over 8
=item L<IO::Iron::IronCache::Client|IO::Iron::IronCache::Client>
=item L<IO::Iron::IronMQ::Client|IO::Iron::IronMQ::Client>
=item L<IO::Iron::IronWorker::Client|IO::Iron::IronWorker::Client>
=back
IO-Iron code is available at Github: L<IO-Iron|https://github.com/mikkoi/io-iron>
for download with Git: L<https://github.com/mikkoi/io-iron.git|https://github.com/mikkoi/io-iron.git>.
=head2 IO::Iron
Package IO::Iron is only a "convenience" module for quick startup.
The three functions provided are L<ironcache|/#ironcache>,
L<ironmq|/#ironmq> and L<ironworker|/#ironworker>.
The following parameters can be given to each of them as hash item type
parameters. See section L<SYNOPSIS|/#SYNOPSIS> for an example.
=over 8
=item C<project_id>, The ID of the project to use for requests.
=item C<token>, The OAuth token that is used to authenticate requests.
=item C<host>, The domain name the API can be located at. E.g. 'mq-aws-us-east-1.iron.io/1'.
=item C<protocol>, The protocol that will be used to communicate with the API. Defaults to "https".
=item C<port>, The port to connect to the API through. Defaults to 443.
=item C<api_version>, The version of the API to connect through. Defaults to the version supported by the client.
=item C<host_path_prefix>, Path prefix to the RESTful url. Defaults to '/1'. Used with non-standard clouds/emergency service back up addresses.
=item C<timeout>, REST client timeout (for REST calls accessing IronMQ.)
=item C<config>, Config filename with path if required.
=back
You can also give the parameters in the config file F<.iron.json> or
F<iron.json> (in local directory) or as environmental variables. Please read
L<Configuring the Official Client Libraries|http://dev.iron.io/mq/reference/configuration/> for further details.
=head3 Client Documentation
Please read individual client's documentation for using them.
=cut
=head1 TESTING
Subdirectory F<integ_t> contains "integration" tests which require an active Iron.io account and Internet connection.
To run the tests, create first three files in the main directory:
F<iron_cache.json>, F<iron_mq.json>, F<iron_worker.json>.
Set at least the following attributes: B<project_id>, B<token> and B<host>.
Execute B<prove> (L<prove|https://metacpan.org/pod/distribution/TAP-Parser/bin/prove>), e.g. B<prove -lv -Iinteg_t integ_t\Iron\iron_all.t>.

=head1 ACKNOWLEDGMENTS
Cool idea, "message queue in the cloud": L<http://www.iron.io/|http://www.iron.io/>.
And well implemented, too, with webhooks for several functions!
=head1 TODO
=over 4
=item * Implement IO::Iron::IronWorker (partly done).
=item * The IronMQ client needs to control the queues, perhaps using semafores.
=item * A buffer mechanism to keep the messages while the IronMQ REST service is unavailable. IO::Iron::IronMQ::ASyncPush?
=item * Implement push queues.
=item * Mock IronMQ for testing.
=item * Handle message size (total), delay, timeout and expiration min-max values.
=over 4
=item * Message Var Default Maximum Notes
=item * Message Size -- 64KB Includes the entire request (delay, timeout, expiration).
=item * Delay 0sec 604,800sec Message is made available on queue after the delay expires.
=item * Timeout 60sec 86,400sec Message goes back on queue after timeout unless deleted.
=item * Expiration 604,800sec 2,592,000sec Equates to 7 days and 30 days, respectively.
=item * Messages per Get 1 100 One or more messages can be handled at a time.
=back
=item * Option to delete queue when IO::Iron::IronMQ::Queue object goes to garbage collection?
=item * Verify the client is connected when created (by calling queues?)
=item * Rethink the using of REST:Client. Since message queues often involve a lot of traffic
but always to the same address, we need to optimize REST:Client usage.
=item * Change from JSON to JSON::Any.
