[Pkg-gmagick-im-team] Bug#763686: imagemagick: identify -quiet has non zero exit code on warnings

[Cédric Boutillier]

Package: imagemagick
Version: 8:6.8.9.6-4
Severity: important
Control: blocks 761532 with -1

Dear Maintainer,

When running the following command:

identify -quiet -ping -format "%w %h\n" erroneous.jpg; echo $?

I get the following output

10 10
1

Without the -quiet option, I get an additional line of output:

identify: Corrupt JPEG data: 2 extraneous bytes before marker 0xdb `/home/boutil/debian/pkg-ruby-extras/ruby-mini-magick/spec/files/erroneous.jpg' @ warning/jpeg.c/JPEGWarningHandler/352.

According to the documentation for the quiet option, the warning should
be ignored.


With 8:6.8.8.9-3, the exit code was 0.

This change of behavior breaks a wrapper for ImageMagick, packaged as
ruby-mini-magick. Commands on erroneous images now are causing errors.

A similar problem, reported by one of the upstream developers of
ruby-mini-magick about non wanted positive exit codes can be found here:

http://www.imagemagick.org/discourse-server/viewtopic.php?f=3&t=26300&p=115618&hilit=identify#p115618

It seems it is fixed in 6.8.9.9.

Attached is the erroneous.jpg file.

Best wishes,

Cédric
