[Bug 1046006] New: Slicing a .stl file fails if multiple threads are configured

[Red Hat Bugzilla]

https://bugzilla.redhat.com/show_bug.cgi?id=1046006

            Bug ID: 1046006
           Summary: Slicing a .stl file fails if multiple threads are
                    configured
           Product: Fedora
           Version: 20
         Component: slic3r
          Severity: high
          Assignee: mhroncok(a)redhat.com
          Reporter: neil(a)darlow.co.uk
        QA Contact: extras-qa(a)fedoraproject.org
                CC: mhroncok(a)redhat.com,
                    perl-devel(a)lists.fedoraproject.org



Description of problem:
If 2 (the default) or higher is selected in Print Settings|Advanced|Threads an
error is reported and slicing fails.

Version-Release number of selected component (if applicable):
slic3r-1.0.0-0.2.RC1.fc20.x86_64

How reproducible:
Every time

Steps to Reproduce:
1. Attempt to slice a .stl file with default settings
2. Observe error and slicing failure

Actual results:
Can't locate package GLUquadricObjPtr for @OpenGL::Quad::ISA at
/usr/share/perl5/vendor_perl/Slic3r.pm line 111.

Expected results:
Slicing should be performed without error.

Additional info:
Reducing the Threads value to 1 permits slicing to be performed.
I have reported this upstream as Issue #1636 at
https://github.com/alexrj/Slic3r

I cannot reproduce the issue. Maybe it's some package I have installed and you
don't (and that is missed as a Require). I'm trying to reproduce this in
virtual environment.

Thanks for reporting this upstream.

Oh, are you using Quick slice from file menu? I can reproduce it then.

This should fix it:

Here is a scratch build of slic3r 1.0.0RC.

http://koji.fedoraproject.org/koji/taskinfo?taskID=6353379

Could you please test, if it crashes for you too, when doing a quick slice with
2+ threads?

--- Comment #5 from Neil Darlow <neil(a)darlow.co.uk&gt; ---
ABRT was invoked and reported that Perl had caught a SIGABRT.

This was with 2 threads selected and reducing threads to 1 allows Quick Slice
and Save As... to work correctly.

This is proving to be quite a puzzle.

--- Comment #6 from Miro Hrončok <mhroncok(a)redhat.com&gt; ---
Thanks for testing it.

In the meantime, as a workaround, I recommend you either add the STL to the
plater and use Export GCODE button, or if you want to be really quick, use
command line interface to slice a single STL file.

slic3r 1.0.0RC3 http://koji.fedoraproject.org/koji/taskinfo?taskID=6603224

Still crashes. I think this might be in wxPerl somewhere :(

Slic3r 1.1.7 seems to remove thread option. Quick slice works.

You can test it on F21, slic3r 1.1.7 is pending to testing.

I do not have F21 but I have Slic3r-1.1.7 installed from tarball on F20.

The Threads option is still there for me under Print Settings|Advanced at the
bottom of the dialog.

Fedora 21 slic3r 1.1.7 screenshot

This is what I see in F21. But running from binary tarball displays that
option, as you say. Weird. Maybe a missing dependency.

lib/Slic3r.pm:    $have_threads = $Config{useithreads} && eval "use threads;
use threads::shared; use Thread::Queue; 1";

I'll check these.

--- Comment #15 from Neil Darlow <neil(a)darlow.co.uk&gt; ---
That is a pretty big clue to what is happening.

Slic3r-1.1.7 from tarball *does not* exhibit this bug but we cannot exclude a
packaging problem.

I am no Perl expert but:

&& eval "use threads; use threads::shared; use Thread::Queue; 1";

looks suspicious.

It obviously checks for various threading modules and the "1" is presumably for
when none is detected but does it act as if something has been detected? I am
wondering if that should actually be "0"?

Thread::Queue it is, when installed, it adds the option. And the crash is still

--- Comment #20 from Fedora End Of Life <endoflife(a)fedoraproject.org&gt; ---
This message is a reminder that Fedora 20 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 20. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '20'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not 
able to fix it before Fedora 20 is end of life. If you would still like 
to see this bug fixed and are able to reproduce it against a later version 
of Fedora, you are encouraged  change the 'version' to a later Fedora 
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.
