NAME

Minion::Job - Minion job

SYNOPSIS

use Minion::Job;

my $job = Minion::Job->new(id => $id, minion => $minion, task => 'foo');

DESCRIPTION

Minion::Job is a container for Minion jobs.

EVENTS

Minion::Job inherits all events from Mojo::EventEmitter and can emit the following new ones.

failed

$job->on(failed => sub {
  my ($job, $err) = @_;
  ...
});

Emitted in the worker process managing this job or the process performing it, after it has transitioned to the failed state.

$job->on(failed => sub {
  my ($job, $err) = @_;
  say "Something went wrong: $err";
});

finished

$job->on(finished => sub {
  my ($job, $result) = @_;
  ...
});

Emitted in the worker process managing this job or the process performing it, after it has transitioned to the finished state.

$job->on(finished => sub {
  my ($job, $result) = @_;
  my $id = $job->id;
  say "Job $id is finished.";
});

spawn

$job->on(spawn => sub {
  my ($job, $pid) = @_;
  ...
});

Emitted in the worker process managing this job, after a new process has been spawned for processing.

$job->on(spawn => sub {
  my ($job, $pid) = @_;
  my $id = $job->id;
  say "Job $id running in process $pid";
});

start

$job->on(start => sub {
  my $job = shift;
  ...
});

Emitted in the process performing this job, after it has been spawned.

$job->on(start => sub {
  my $job = shift;
  $0 = $job->id;
});

ATTRIBUTES

Minion::Job implements the following attributes.

args

my $args = $job->args;
$job     = $job->args([]);

Arguments passed to task.

id

my $id = $job->id;
$job   = $job->id($id);

Job id.

minion

my $minion = $job->minion;
$job       = $job->minion(Minion->new);

Minion object this job belongs to.

retries

my $retries = $job->retries;
$job        = $job->retries(5);

Number of times job has been retried.

task

my $task = $job->task;
$job     = $job->task('foo');

Task name.

METHODS

Minion::Job inherits all methods from Mojo::EventEmitter and implements the following new ones.

app

my $app = $job->app;

Get application from "app" in Minion.

# Longer version
my $app = $job->minion->app;

fail

my $bool = $job->fail;
my $bool = $job->fail('Something went wrong!');
my $bool = $job->fail({whatever => 'Something went wrong!'});

Transition from active to failed state, and if there are attempts remaining, transition back to inactive with a delay based on "backoff" in Minion.

finish

my $bool = $job->finish;
my $bool = $job->finish('All went well!');
my $bool = $job->finish({whatever => 'All went well!'});

Transition from active to finished state.

info

my $info = $job->info;

Get job information.

# Check job state
my $state = $job->info->{state};

# Get job metadata
my $progress = $job->info->{notes}{progress};

# Get job result
my $result = $job->info->{result};

These fields are currently available:

args
args => ['foo', 'bar']

Job arguments.

attempts
attempts => 25

Number of times performing this job will be attempted.

children
children => ['10026', '10027', '10028']

Jobs depending on this job.

created
created => 784111777

Epoch time job was created.

delayed
delayed => 784111777

Epoch time job was delayed to.

finished
finished => 784111777

Epoch time job was finished.

notes
notes => {foo => 'bar', baz => [1, 2, 3]}

Hash reference with arbitrary metadata for this job.

parents
parents => ['10023', '10024', '10025']

Jobs this job depends on.

priority
priority => 3

Job priority.

queue
queue => 'important'

Queue name.

result
result => 'All went well!'

Job result.

retried
retried => 784111777

Epoch time job has been retried.

retries
retries => 3

Number of times job has been retried.

started
started => 784111777

Epoch time job was started.

state
state => 'inactive'

Current job state, usually active, failed, finished or inactive.

task
task => 'foo'

Task name.

worker
worker => '154'

Id of worker that is processing the job.

is_finished

my $bool = $job->is_finished;

Check if job performed with "start" is finished.

note

my $bool = $job->note(foo => 'bar');

Change a metadata field for this job. The new value will get serialized by "backend" in Minion (often with Mojo::JSON), so you shouldn't send objects and be careful with binary data, nested data structures with hash and array references are fine though.

# Share progress information
$job->note(progress => 95);

# Share stats
$job->note(stats => {utime => '0.012628', stime => '0.002429'});

perform

$job->perform;

Perform job in new process and wait for it to finish.

pid

my $pid = $job->pid;

Process id of the process spawned by "start" if available.

remove

my $bool = $job->remove;

Remove failed, finished or inactive job from queue.

retry

my $bool = $job->retry;
my $bool = $job->retry({delay => 10});

Transition job back to inactive state, already inactive jobs may also be retried to change options.

These options are currently available:

delay
delay => 10

Delay job for this many seconds (from now), defaults to 0.

priority
priority => 5

Job priority.

queue
queue => 'important'

Queue to put job in.

start

$job = $job->start;

Perform job in new process, but do not wait for it to finish.

# Perform two jobs concurrently
$job1->start;
$job2->start;
my ($first, $second);
sleep 1
  until $first ||= $job1->is_finished and $second ||= $job2->is_finished;

stop

$job->stop;

Stop job performed with "start" immediately.
