Warning when uploading Thumbnail Replacement

[iamdamosuzuki]

I get the following warning when trying to upload a Thumb Replacement for any Content Model:

Warning: file_get_contents({MY_SITE}/system/temporary/p1bt2prjfcugc1fnt174r1vln1ltvp.tmp): failed to open stream: HTTP request failed! HTTP/1.0 403 Forbidden in islandora_default_thumbs_admin_submit() (line 180 of /var/www/drupal/sites/all/modules/islandora_default_thumbs-7.x/includes/admin.form.inc).

This error does not appear when uploading an image to the Thumbnail Source in the Compare Image Configuration, which appears to working fine.

Was unable to reproduce this locally. If I had to take an educated guess the issue appears to be the configuration of where your temporary directory is. Plupload appends ".tmp" onto those files (http://cgit.drupalcode.org/plupload/tree/plupload.module?h=7.x-1.x#n359) when storing the uploads. It's worth noting, like you mentioned, that it's not plupload tossing that file_get_contents warning but I'd have a look at your temporary directory regardless.

For example when looking at this on my local, with a different default thumbnail, the path that is attempting to be compared to is:
public://islandora_default_thumbs/replace_icons/test.jpg.

@iamdamosuzuki and I are working together on this.

First, I tried changing the temporary file directory, temporary:// was set to /tmp but islandora_default_thumbs was looking in public://system/temporary. I changed the temporary directory (via admin/config/media/file-system) to /var/www/drupal/sites/default/files/system/temporary.

temporary files are being saved to this location when uploaded via plupload.
/var/www/drupal/sites/default/files/system/temporary# ls
p1c0nev5vh1l9j7dsif2ljjdjp.tmp

Next I verified permissions for www-data:
/var/www/drupal/sites/default/files/system/temporary# ls -ld .
drwxr-xr-x 2 www-data www-data 4096 Dec 6 19:05 .

but we're still getting the same error
