Description Germán Poo-Caamaño 2013-04-22 23:47:32 UTC

I opened a proceeding, searched by 'forge' and evince got stuck in 59%.  I had
tried searching with other documents of >140 pages and I could not reproduce
the problem.  Neither with smaller documents.

I am not attaching the document because is big (1.6MB) and I am not sure about
its copyright (usually these are behind a paywall).  However, I found a link
that would make the trick for you to reproduce the error:

http://opensource.ucc.ie/icse2003/3rd-WS-on-OSS-Engineering.pdf

Here is the stacktrace after I interrupted evince because it was taking too
long.  Same thing with poppler-glib-demo.  The stacktrace is the following
with poppler master:

Starting program: /home/gpoo/code/evince/install/bin/poppler-glib-demo '/home/gpoo/Documentos/Papers/Conference, Portland, May/Conference, Portland, May - 2003 - Automating the measurement of open source projects.pdf'

Comment 1 Jose Aliste 2013-04-23 00:08:04 UTC

the problem is in page 83 of the attached test case. The problem lies in a table that is rotated 90 degrees... And the text-layout extraction algorithm does not cope with the rotation of glpyhs... as a by product of this, poppler glib frontend can't render that page.

Comment 2 Germán Poo-Caamaño 2013-04-23 18:01:51 UTC

Created attachment 78392 [details]
PDF test case (page 83)

The original file is linked.  Now I am attaching only the page that helps to reproduce the issue.

Comment 3 Albert Astals Cid 2013-04-23 22:00:42 UTC

Another of those TextOutputDev is slow problems, don't think the glib frontend is the culprit, pdftotext takes ages too.

FWIW, xpdf shows the page rendered very fast but then it gets stuck, too.  I guess it is because is getting the text or something like that, which makes sense to me given pdftocairo renders the page fast, too.

Albert, of course you are right, the problem is in the textOutputDdev. My comment was just about the fact that the popple-glib render code does two things at the same time, it renders the page AND it gets the text. Thus, evince won't render that page since poppler_page_render won't return.
