GetMagickThreadSupport problem with mod_perl

Hey,

I'm using PerlMagick in a perl module called as a output filter by Apache. This module is scaling my images and returns the output to apache. When i run one concurrent request with ab (apache benchmark) everything works fine. But if i increase the concurrency number I get several assertion errors in the Apache log, but not for all request - just some of them... 2000 request with 30 concurrent will give me like 4 errors in the log.

Here is some output:

[Tue Oct 14 15:54:27 2008] [notice] child pid 2013 exit signal Aborted (6)

I get the feeling this is a problem with non-safe threads? I've not compiled without saftey.

Grab ImageMagick 6.4.4-6, the latest release. We have addressed a few thread-safety issues in recent releases of ImageMagick. If 6.4.4-6 exhibits the same thread problems, let us know and we will try to reproduce and fix the problem.

Thanks for the reply, I've now tried ImageMagick-6.4.4-7.tar.gz without luck. I still get the problem when I increase number of concurrent requests:

I'm able to reproduce with following setup:

/etc/httpd/conf/httpd.conf
LoadModule perl_module modules/mod_perl.so
PerlSwitches -I /opt/perl/
PerlOutputFilterHandler Test::Magick

/opt/perl/Test/Magick.pm

Code: Select all

package Test::Magick;

use APR::Table();
use Image::Magick();
use Apache2::RequestRec();

use base qw(Apache2::Filter);
use Apache2::Const -compile => qw(OK);

sub handler : FilterRequestHandler
{
    my $f = shift;
    my $data = "";
    my ($image, $buffer, @x);

    while ($f->read($buffer, 1024))
    {
        $data .= $buffer;
    }

    $image = new Image::Magick();

    $image->BlobToImage($data);

    @x = $image->ImageToBlob();

    $f->r->headers_out->set("Content-Length"=>length($x[0]));

    $f->print($x[0]);

    undef $image;

    return Apache2::Const::OK;
}

1;

__END__
ab -n 5000 -c 30 http://localhost/image.png

Apache benchmark should die pretty soon with: apr_socket_recv: Connection reset by peer (104)

Unfortunately we cannot reproduce the problem although we know why the problem may occur. Can you post the output of this command:
  • identify -list configure
And post your OS and release # and your Apache version.

Grab ImageMagick-6.4.4-8 Beta from ftp://magick.imagemagick.org/pub/ImageMagick/beta in about 2 hours and see if that fixes or reduces the race condition.

Okey, I grabed ImageMagick-6.4.4-9.tar.gz and have now installed it.

Something obviously changed, but unfortunately, not to anything better:

I can add that pictures are stored on a net storage that may add a slight delay in the serve process. Maybe this increases the possibility for things to collide?

Edit - got another failure in the log:

Since we cannot reproduce the problem locally, we'll debug remotely. Go to magick/magick.c and add a return just before the last line of UnregisterMagickInfo():

Code: Select all

  RelinquishSemaphoreInfo(magick_semaphore);
return(MagickTrue);
  return(DeleteNodeByValueFromSplayTree(magick_list,p));
Next prevent the magick list from being destroyed in DestroyMagickList(). Add a return as the first line:

Code: Select all

return;
  AcquireSemaphoreInfo(&magick_semaphore);
  if (magick_list != (SplayTreeInfo *) NULL)
    magick_list=DestroySplayTree(magick_list);
The thinking is that the magick list splay-tree is being deleted while the node is still in use.

Rebuild and install ImageMagick.

Does the problem still occur? Now try ab with a JPEG image instead of PNG. Does that make any difference?

Unless we can reproduce the problem locally, we are currently unable to identify and fix the problem. The curious thing is that we are testing on a quad-core system similar to yours (same OS but server rather than client, same Apache) but we cannot get ab to cause any of the sub-processes to fail. If you have other ideas on how we can get your filter to fail that would be helpful. Be sure to check and make sure you only have one version of ImageMagick and PerlMagick installed.

Okey, other than storing my images on NFS, I'm running ImageMagick from a local directory.
Stored in /prun/img/server/imagemagick. In my Perl script I'm using following to get this to work:

$ENV{"MAGICK_HOME"} = "/prun/img/server/imagemagick";
$ENV{"MAGICK_CODER_MODULE_PATH"} = "/prun/img/server/imagemagick/lib/ImageMagick-6.4.4/modules-Q16/coders";

Some of my httpd.conf settings:

KeepAlive On
MaxKeepAliveRequests 100
KeepAliveTimeout 15

<IfModule prefork.c>
StartServers 8
MinSpareServers 5
MaxSpareServers 20
ServerLimit 256
MaxClients 256
MaxRequestsPerChild 4000
</IfModule>

<FilesMatch "\.(jpg|jpeg|gif|png)">
Header unset Vary
</FilesMatch>

DocumentRoot /images/

<Directory /images/>
Options FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all
</Directory>

If this does not work, the only thing I can think of is the mod_perl version. May this be my compiler or libs? Is it possible to get a version compiled with ./configure --prefix=/prun/img/server/imagemagick from your machine?

We replicated your environment as posted and still ab runs to completion without reporting any problems in the log. Unfortunately we cannot build an ImageMagick distribution for you. Our gcc version is:

Try setting MAGICK_CONFIGURE_PATH. Maybe ImageMagick is not picking up its configuration files properly.

Post the output of these commands:

    convert -debug configure logo.png null:

MAGICK_CONFIGURE_PATH did not work either.

I got a little bit older gcc.. 4.0.2.

I'll try to compile with newer versions of libpng, libjpeg, libtiff and gcc. I'll be back with results.

Problem solved. I ran Apache as a worker. Fixed by removing the entry in /etc/sysconfig/httpd and restarting Apache.

Conclusion, do not use Apache worker together with ImageMagick.

Thank you for your time magick!
