#22869: Large Image Uploads Don't Error Well
 Reporter:  Ipstenu          |       Type:  defect (bug)
   Status:  new              |   Priority:  normal
Milestone:  Awaiting Review  |  Component:  Media

 Related to #22849 but not restricted to the new uploader. Happens on 3.4
 and 3.5 in different ways.

 To Reproduce: Upload https://objects.dreamhost.com/ipstenu-images
 /sunset_2_22_11_by_kenshinkyo-d3a6slk.jpeg to your WP install in the
 media-new.php page

 Note: Image is 12600x9450 and 4.9MB

 Expected Outcomes:

 * Shared hosted without a lot of memory: Failure, not enough memory, no
 image uploaded.
 * VPS/Dedicated with tons of memory: Success

 Actual outcomes:

 * VPS as expected.
 * Shared not so much. You get the errors as expected however the failure
 is not correct. The image actually does upload, contrary to the errors,
 however no thumbnails are made, which then causes a memory problem as the
 full size image shows when you go to any media library view (in lieu of
 actual thumbnails). This crashed Chrome (as @markjaquith saw when we were
 testing Monday night) until I deleted the large images.

 The actual issue is on thumbnail creation, so the best 'fix' I can think
 of is if on failed thumbnail gen, it nukes the master image, but I don't
 know if that would make sense since some of the thumbnail gen might be on
 extra image sizes set by themes/plugins. Then again, do you want those if
 all fail?
