[fuel-docs] Release Notes PDF doesn't work in FireFox

[Ivan Kolodyazhny]

FireFox opens blank document instead Release Notes.

[Ivan Kolodyazhny (e0ne)]

Looks like FireFox or FireFox plugin issue

[Andrey Danin (gcon-monolake)]

I have same trouble.
Ubuntu 12.04 Firefox 21.0 plugin PDF.js

[Tatyanka (tatyana-leontovich)]

I have not such problem
Mac Os 10.8.5 Firefox 25.0.1 without plugins for PDF

[Mike Scherbakov (mihgen)]

Andrey - but you can download fine, and then open the document with PDF reader on Ubuntu just fine, right? So I'm closing this then.

[Vladimir Sharshov (vsharshov)]

I have such problem too in FireFox 25.01 (standart ubuntu browser) without additional pdf plugins. Evince (document viewer) open it without any problem.

[Miroslav Anashkin (manashkin)]

Adobe Reader plugin under Firefox 25.01 reports "This document might not be displayed correctly" as well and shows empty page.

I'll try to debug this

[Dmitry Ilyin (idv1985)]

All our PDF files, not only RelNotes are slightly corrupted and have broken XREF table.
This table contains index of objects and if it's broken viewer will have to reindex the file.
It takes a lot of time and looks like PDF.js of some firefox versions sometimes hang.

   **** Warning: An error occurred while reading an XREF table.
   **** The file has been damaged. This may have been caused
   **** by a problem while converting or transfering the file.
   **** Ghostscript will attempt to recover the data.
   **** Warning: There are objects with matching object and generation
   **** numbers. The accuracy of the resulting image is unknown.

   **** This file had errors that were repaired or ignored.
   **** The file was produced by:
   **** >>>> ReportLab PDF Library - www.reportlab.com <<<<
   **** Please notify the author of the software that produced this
   **** file that it does not conform to Adobe's published PDF
   **** specification.

This files can be easily fixed:

repair_pdf.sh Mirantis-OpenStack-4.0-RelNotes.pdf Mirantis-OpenStack-4.0-RelNotes-fixed.pdf
gs -o "${2}" -sDEVICE=pdfwrite -dPDFSETTINGS=/prepress "${1}"

It makes file load much faster and without errors. So we can either process of files before release or
do something with >>>> ReportLab PDF Library - www.reportlab.com <<<< service we are using.

Passing files through prepress distiller also reduces file size

It became even worse. Now GhostScript doesn't help and crushes.
