Status: RESOLVED FIXED

(Firefox :: PDF Viewer, defect, P2)

Description

[Dan Jacobson]

User Agent: Mozilla/5.0 (X11; Linux i686; rv:27.0) Gecko/20100101 Firefox/27.0 Iceweasel/27.0a2 (Beta/Release)
Build ID: 20131115004004

Steps to reproduce:

# set http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19810021384_1981021384.pdf
# su - nobody -c 'HOME=/tmp firefox '"$@" #virgin Firefox






Actual results:

We see it stalls just a tiny bit into the download there in PDFJS. Same with the rest of the PDFs on that site.


Expected results:

Should have got the whole file like wget.

HTTP request and response look like:

==========

Per RFC 2616: "When an HTTP message includes the content of a single range (for example, a response to a request for a single range, or to a request for a set of ranges that overlap without any holes), this content is transmitted with a Content-Range header, and a Content-Length header showing the number of bytes actually transferred... A response to a request for a single range MUST NOT be sent using the multipart/byteranges media type."

That makes response from NASA server invalid. It might be possible to implement a workaround/hack on the PDF.js that will discard invalid response (e.g. by checking the headers similar to bug 918291) and start fetching the whole file.

On latest Aurora (20140106004002) the pdf is not loaded, setting this issue as NEW.
