Jean-Francois Lalande	Saturday 08 August 2009 4:48:57 am Hello, I cannot execute the convert command for image convertion. I obtain this in the debug info: Failed executing: /usr/local/bin/convert '-geometry' '600x600>' 'var/plain_site/storage/images/media/images/diagramme2/272-1-fre-FR/Diagramme2.png' 'PNG:var/plain_site/storage/images/media/images/diagramme2/272-1-fre-FR/Diagramme2_reference.png' I suspected the configuration of PHP and I checked the safe_mode which is enabled. I made a link to convert and authorized php to execute convert. But in the apache's logs, I obtained this: convert: invalid argument for option `600x600\>': -geometry. So I made a small script of test: <? exec("/usr/local/bin/convert '-geometry' '600x600>' logo.jpg out.jpg"); ?> that produced the same error. It seems that php (or apache ?) is adding a backslash in front of the > that is used by ezpublish. Maybe someone knows how to setup correctly apache/php or Ezpublish to avoid this problem. Maybe this is a problem to include somewhere in the documentation/faq of Ezpublish. Any help is appreciated :) Jean-Francois.
Jean-Francois Lalande	Saturday 08 August 2009 7:02:22 am I think maybe this is not a problem with Apache and PHP. The documentation of exec indicates that "With safe mode enabled, the command string is escaped with escapeshellcmd(). Thus, echo y \| echo x becomes echo y \\| echo x.". So maybe it is a bug of Ezpublish that sends a commande line with a ">" inside which is escaped with a "\". Can anyone confirm this ? If it is right I can submit a bug report.

Hello,

I cannot execute the convert command for image convertion. I obtain this in the debug info:

Failed executing: /usr/local/bin/convert '-geometry' '600x600>' 'var/plain_site/storage/images/media/images/diagramme2/272-1-fre-FR/Diagramme2.png' 'PNG:var/plain_site/storage/images/media/images/diagramme2/272-1-fre-FR/Diagramme2_reference.png'

I suspected the configuration of PHP and I checked the safe_mode which is enabled. I made a link to convert and authorized php to execute convert.

But in the apache's logs, I obtained this:

convert: invalid argument for option `600x600\>': -geometry.

So I made a small script of test:
<?
exec("/usr/local/bin/convert '-geometry' '600x600>' logo.jpg out.jpg");
?>

that produced the same error. It seems that php (or apache ?) is adding a backslash in front of the > that is used by ezpublish.

Maybe someone knows how to setup correctly apache/php or Ezpublish to avoid this problem. Maybe this is a problem to include somewhere in the documentation/faq of Ezpublish.

Any help is appreciated :)

Jean-Francois.
