Description Marko Myllynen 2011-06-29 20:08:52 UTC
Description of problem:
When opening the JPEG image linked below applications like eog/firefox/gimp start using huge amounts of memory rendering a system with 1 GB memory unusable and sometimes invoking the OOM killer.

http://upload.wikimedia.org/wikipedia/commons/2/21/Earthlights_dmsp.jpg

Version-Release number of selected component (if applicable):
libjpeg-turbo-1.1.0-2.fc15.i686

How reproducible:
Always.

Steps to Reproduce:
1. wget http://upload.wikimedia.org/wikipedia/commons/2/21/Earthlights_dmsp.jpg
2. eog Earthlights_dmsp.jpg or firefox Earthlights_dmsp.jpg or gimp Earthlights_dmsp.jpg

Comment 1 Adam Tkac 2011-07-04 15:17:33 UTC
The main problem is that image is really huge. I converted it via djpeg (djpeg -bmp Earthlights_dmsp.jpg > earth.bmp) utility to bmp and the file utility shows:

$ file earth.bmp 
earth.bmp: PC bitmap, Windows 3.x format, 16384 x 8192 x 24

It means image loaded inside memory (in commonly used RGBA format) occupies at least 16384*8192*4 bytes which is around 0.5 GB of memory.

Per `valgrind --tool=massif` djpeg utility consumed max 384.7 MB so it means decoding routines in libjpeg-turbo is not the main problem.

When I opened both images (bmp and jpeg) via /usr/bin/qiv image viewer then massif told both cases consumed 1.376 GB of memory. So there is no difference in memory consumption between jpeg and bmp cases.

Vast majority of allocations were performed via gdk-pixbuf2 routines so I assume gdk-pixbuf2 stores pixel data in too large structures.

Reassigning to gdk-pixbuf2 for further inspection.

Comment 2 Fedora End Of Life 2012-08-07 19:20:58 UTC
This message is a notice that Fedora 15 is now at end of life. Fedora
has stopped maintaining and issuing updates for Fedora 15. It is
Fedora's policy to close all bug reports from releases that are no
longer maintained. At this time, all open bugs with a Fedora 'version'
of '15' have been closed as WONTFIX.

(Please note: Our normal process is to give advanced warning of this
occurring, but we forgot to do that. A thousand apologies.)

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

Bug Reporter: Thank you for reporting this issue and we are sorry that
we were unable to fix it before Fedora 15 reached 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 to click on
"Clone This Bug" (top right of this page) and open it against that
version of Fedora.

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.

The process we are following is described here:
