PDF-specific Bug in the ZServer implementation??? Or just strange behavoiur of IE?
Hi! This is my first post in the new year, so best wishes for 2002 from Germany! And on we go with my problem: I have a ZClass-based Class derived from File. It holds PDF documents. SOME (not all) of them do not auto-open in Acrobat Reader as they are supposed to if MS IE 5.x is used. Opera etc. seem to work. The files themselves are o.k., and opening in Acrobat Reader AFTER downloading (via right mouseclick/save as) works fine, too. If the same document that doesn't auto-open when downloaded fom the Zope server is downloaded from plain Apache, it works ... The configuration is Zope 2.4.1 (binary release, python 2.1, linux2-x86), python 2.1.0, linux2 on a SuSE Linux with Apache as Proxy server (via proxy_pass). I checked the HTTP header with WGET, and they are identical for working and non-working PDF docs. The mime type is set to application/pdf ... Any hints on that? Joachim

Hmmm, sounds like maybe the http range code isn't quite working maybe? What version of Acrobat Reader? Maybe try an older version. If that works, that new range code might be to blame. /---------------------------------------------------\ Casey Duncan, Sr. Web Developer National Legal Aid and Defender Association c.duncan@nlada.org \---------------------------------------------------/
Martijn fixed that problem some weeks ago. The fixes are in the CVS now.

Hi! This was a really quick response! Thanks a lot. Just one additional question: What is the best approach to upgrading to the new code? Replacing the ZServer code by the CVS one? Is the patch in the latest 2.5 beta, too?

Hi, I have the same problem and want to fix it in Zope 2.4.3. Can anybody give a short description how to proceed ? Thanks Dirk Joachim Werner schrieb:

Yes, the changes are in 2.5.0b3 as well (check the CHANGES.txt file when in doubt :)). -- Martijn Pieters | Software Engineer mailto:mj@zope.com | Zope Corporation http://www.zope.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------

The code only applies to OFS/Image.py (only File and Image objects support HTTP Range) and ZPublisher/HTTPRangeSupport.py. I've attached the versions for a Zope 2.4.x installation, just drop them in the correct places in your current Zope setup. -- Martijn Pieters | Software Engineer mailto:mj@zope.com | Zope Corporation http://www.zope.com/ | Creators of Zope http://www.zope.org/ ---------------------------------------------
BRILLIANT!! One headache fixed. Martijn "Analgesic" Pieters, you are my hero for the day. Thank you.

-> > Any hints on that? The failure to open a PDF can be caused by the browser never knowing that file is all done downloading. If Zope is running on WindowsNT and you're using Solaris (either as the workstation or else as an HTTP proxy) then you may be getting a rare bug between the WindowsNT and Solaris TCP/IP stacks. The Solaris packet sends an out-of-order FIN (or was it just a FIN with no data? Can't remember) and the WindowsNT stack never closes the connection, NOR does it acknowledge the last packet before the FIN, so you wind up just stuck. I.e., you'll see a failed PDF download. Sun and MS both know about this, but neither will claim responsibility. I don't remember the exact details, but we saw this problem a few months ago. It was more prevalent with PDFs than anything else because of large filesize and the fact that I.E. must spawn the PDF "control" (aka 'widget') with the browser. Just a thought. --Derek
