Minion::Job - Minion job
use Minion::Job; my $job = Minion::Job->new(id => $id, minion => $minion, task => 'foo');
Minion::Job is a container for Minion jobs.
Minion::Job inherits all events from Mojo::EventEmitter and can emit the following new ones.
$job->on(failed => sub {
my ($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";
});
$job->on(finish => sub {
my $job = shift;
...
});
Emitted in the process performing this job if the task was successful. Note that this event is EXPERIMENTAL and might change without warning!
$job->on(finish => sub {
my $job = shift;
my $id = $job->id;
my $task = $job->task;
$job->app->log->debug(qq{Job "$id" was performed with task "$task"});
});
$job->on(finished => sub {
my ($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.";
});
$job->on(reap => sub {
my ($job, $pid) = @_;
...
});
Emitted in the worker process managing this job, after the process performing it has exited.
$job->on(reap => sub {
my ($job, $pid) = @_;
my $id = $job->id;
say "Job $id ran in process $pid";
});
$job->on(spawn => sub {
my ($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";
});
$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;
});
Minion::Job implements the following attributes.
my $args = $job->args; $job = $job->args([]);
Arguments passed to task.
my $id = $job->id; $job = $job->id($id);
Job id.
my $minion = $job->minion; $job = $job->minion(Minion->new);
Minion object this job belongs to.
my $retries = $job->retries; $job = $job->retries(5);
Number of times job has been retried.
my $task = $job->task;
$job = $job->task('foo');
Task name.
Minion::Job inherits all methods from Mojo::EventEmitter and implements the following new ones.
my $app = $job->app;
Get application from "app" in Minion.
# Longer version my $app = $job->minion->app;
my $err = $job->execute;
Perform job in this process and return "undef" if the task was successful or an exception otherwise.
# Perform job in foreground
if (my $err = $job->execute) { $job->fail($err) }
else { $job->finish }
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 with or without a result, and if there are attempts remaining, transition back to "inactive" with a delay based on "backoff" in Minion.
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 with or without a result.
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 => ['foo', 'bar']
Job arguments.
attempts => 25
Number of times performing this job will be attempted.
children => ['10026', '10027', '10028']
Jobs depending on this job.
created => 784111777
Epoch time job was created.
delayed => 784111777
Epoch time job was delayed to.
finished => 784111777
Epoch time job was finished.
notes => {foo => 'bar', baz => [1, 2, 3]}
Hash reference with arbitrary metadata for this job.
parents => ['10023', '10024', '10025']
Jobs this job depends on.
priority => 3
Job priority.
queue => 'important'
Queue name.
result => 'All went well!'
Job result.
retried => 784111777
Epoch time job has been retried.
retries => 3
Number of times job has been retried.
started => 784111777
Epoch time job was started.
state => 'inactive'
Current job state, usually "active", "failed", "finished" or "inactive".
task => 'foo'
Task name.
worker => '154'
Id of worker that is processing the job.
my $bool = $job->is_finished;
Check if job performed with "start" is finished.
$job->kill('INT');
Send a signal to job performed with "start".
my $bool = $job->note(mojo => 'rocks', minion => 'too');
Change one or more metadata fields for this job. The new values 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'});
$job->perform;
Perform job in new process and wait for it to finish.
my $pid = $job->pid;
Process id of the process spawned by "start" if available.
my $bool = $job->remove;
Remove "failed", "finished" or "inactive" job from queue.
my $bool = $job->retry;
my $bool = $job->retry({delay => 10});
Transition job back to "inactive" state, already "inactive" jobs may also be retried to change options.
These options are currently available:
attempts => 25
Number of times performing this job will be attempted.
delay => 10
Delay job for this many seconds (from now), defaults to 0.
parents => [$id1, $id2, $id3]
Jobs this job depends on.
priority => 5
Job priority.
queue => 'important'
Queue to put job in.
$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;
$job->stop;
Stop job performed with "start" immediately.
