Calling `finish`, `note` etc in task code fails on macOS while communicating over TCP

I'm collecting info on this issue and I know that this report is incomplete. I'd like to record it here while I'm working on it. I think it's specific to macOS, but that's only a hunch. This might be a DBD::Pg issue rather than a Minion issue, too, but I haven't been able to reproduce it without Minion involved. If you've debugged this sort of thing before, I'd appreciate advice on what else I should investigate.

  • Minion version: 10.04
  • Perl version: 5.30.2
  • Operating system: macOS Catalina 10.15.3

Darwin otter.local 19.3.0 Darwin Kernel Version 19.3.0: Thu Jan 9 20:58:23 PST 2020; root:xnu-6153.81.5~1/RELEASE_X86_64 x86_64

  • local Postgresql is 12.2, from the precompiled package from EnterpriseDB. This is what the local DBD::Pg linked against.
  • DBI: 1.643
  • DBD::Pg: 3.11.1
  • remote Postgresql is 12.2, from the precompiled package that ArchLinux installs. Note that ArchLinux treats the Postgres packages oddly because it's confused about the versioning.

Steps to reproduce the behavior

When I call a database-mutating method on the job object inside the task code, the subprocess exits with a failure. The parent process recovers and marks the job as failed. Here's the script I'm playing with:

use v5.30;
use Mojo::Base -strict, -signatures;
use Minion;
use Mojo::Util qw(dumper);

my $minion = Minion->new( Pg => 'postgresql://?service=remote-minion' );

$minion->add_task( sum => sub ( $job, @args ) {
	say "Sum: ARGS: @args";
	my $sum; $sum += $_ for @args;
	say "Sum: About to finish";
	$job->finish( { sum => $sum } );
	say "Sum: After finish";
	} );

my $jobs = 1;
foreach my $i ( 1 .. $jobs ) {
	my @args = map { int rand 100 } 2 .. 3 + int rand 5;
	say "ARGS: @args";
	my $id = $minion->enqueue( sum => \@args );
	say "Enqueued job ID <$id>";
	}

my $worker = $minion->repair->worker->register;

while(1) {
	my $job    = $worker->dequeue(0.5);
	last unless defined $job;

	say "Dequeueing Job id: <", $job->id,
		"> Args: <@{[ join ' ', $job->args->@* ]}>";

	$job->perform;
	last;
	}

$worker->unregister;

Here's the Pg service, with the hostaddr obscured. Nothing else (psql, other DBD::Pg programs) break using this service.

[remote-minion]
dbname=minion
hostaddr=w.x.y.z
port=5432
user=brian
sslmode=require

Now, here's the trick. This same program has no problems running against the same remote Pg server when I run it on an Ubuntu box. This script on the remote machine running against the remote Pg server works just fine.

So, I have another service for a Pg server running on the same laptop. Running this on my MacBook against the local Pg server over TCP fails (job fails because task child exits with an error), but connecting to the local socket works (job finishes normally).

[local-minion]
dbname=minion
host=localhost
user=postgres

[local-minion-socket]
dbname=minion
host=/tmp
user=postgres

Expected behavior

Calling finish, note, etc on the job object in the task code should not cause the subprocess to exit.

Actual behavior

Calling finish, note, etc on the job object in the task code fails somewhere around the code the attempts to make a connection to the database. I tracked the Perl code to a line in DBD::Pg, and this is what I think fails in the child process:

https://github.com/bucardo/dbdpg/blob/ef0f61fdcd5d2dec9271c722dac8bd75ce8def6e/Pg.pm#L258

While logging this in postgres, I do not see an attempt to connect (could be wrong, because there are a lot of connection attempts from Minion). I've traced this with DBI_TRACE=9, and have those very long logs.

I've also traced this with Devel::Trace to watch the Perl path. I think this is the general flow:

  • Task calls $job->finish

  • Minion::Job::finish() calls $self->minion->backend->finish_job($self->id, $self->retries, $result); (note and others have similar calls)

  • Minion::Backend::Pg::finish_job calls Minion::Backend::Pg::_update

  • Minion::Backend::Pg::_update calls $self->pg->db (Mojo::Pg::Database) (with an immediate call to ->query, but it never gets that far.

  • Mojo::Pg::Database->db (Mojo::Pg::db) calls Mojo::Pg::Database->_prepare , which calls Mojo::Pg::Database->_dequeue, which calls DBI->connect(). The DBI options at this point seem right, and I think AutoInactiveDestroy is as it should be:

    {
    "AutoCommit" => 1,
    "AutoInactiveDestroy" => 1,
    "PrintError" => 0,
    "PrintWarn" => 0,
    "RaiseError" => 1
    }

  • DBI->connect ends up in DBD::Pg, particularly DBD::Pg::db::_login, which is last Pure perl line of code executed in the child process. Somewhere in there it fails, which leads me to think that it might not be Minion's fault. However, trying to tickle this without Minion hasn't helped. I can't reproduce this by playing with DBD::Pg without Minion.

  • At this point, the child process exits abnormally without DBI ever connecting. I see that the process gets the SEGV signal.

  • The parent process sees the abnormal exit and switches from finish to fail.

Yea, doesn't look like a Minion problem. Maybe a broken DBD::Pg installation? Can you run the Minion tests against the database?

commented

Oh, running the tests would have been a good idea a week ago. :) I'm strongly suspecting a problem with DBD::Pg too, but I'm still figuring out how to reproduce it without Minion.

$ echo $TEST_ONLINE
postgresql://?service=remote

Some of the tests fail in the same way I describe, then the test run hangs:

Btw. I just ran the tests on macOS without problems in a perlbrew environment.

Which Postgresql installation do you have and were you connecting to a remote machine? Maybe I should be using a different Postgres binary source.

I'm going to compile postgres from source and try everything again.

I compiled Postgres 12.2 myself and recompiled DBD::Pg against it. No problems. Like, something I should have tried a week ago.

Thanks for paying attention though. This isn't a problem for me now, but if someone runs into the same situation, at least they can read this. I still learned a lot about Minion by going through the process, so it wasn't a total waste for me.
