Comment 4 Inge Wallin 2013-07-01 03:58:11 UTC

Now classifies as a crash bug.

Comment 5 Camilla Boemann 2013-08-11 10:20:41 UTC

Nope it still freezes for me

Comment 6 Pierre Ducroquet 2014-09-14 22:20:34 UTC

This is not a bug in the OpenDocument parsing code, rather a layout issue related to the handling of the soft page break in a header element without a preceding paragraph : the layout system starts spawning an infinity of pages (likely resulting in a crash sooner or later).
I'll add a simpler test case with most of the content dropped to make it easier to debug.

Comment 7 Pierre Ducroquet 2014-09-14 22:22:18 UTC

Lighter test-case to narrow down the crash source

Comment 8 Pierre Ducroquet 2014-09-17 07:25:16 UTC

I just found the error in our layout system that creates this crash.
I only have a workaround so far, a usable and clean fix is going to take a bit more thinking.

Work around for this bug - lots of potential side effects, not to merge...

Comment 10 Camilla Boemann 2014-09-17 08:39:03 UTC

So is it the keep with next or the softbreak

Do all those headings have keepWithNext, and then at the end when there is no more space on paper we backtrack them all?

Comment 11 Camilla Boemann 2014-09-17 08:52:21 UTC

To answer my own question - yes all those headings have keep with next and thus we backtrack them all. 
I guess LO/AOO doesn't backtrack in this case - but rather keep them all as nothing else really makes sense - just keeping the first is not any more correct than keeping them all

So the correct solution will be something along the lines of checking if it makes sense at all to back track before really backtracking

what do you say?

Comment 12 Pierre Ducroquet 2014-09-17 09:08:05 UTC

I've started a patch (it's on my home desk, I'll finish it and send it tonight) to give a more meaningfull output in layoutBlock so that the backtrack code can make a wiser decision and not backtrack when we encountered a page break. But the real fix is indeed to do in the backtracking code.

Git commit 643a232d0bb6fb4ccea1ab9c32ebdb0ccc4ca114 by Pierre Ducroquet.
Committed on 18/09/2014 at 19:53.
Pushed by ducroquet into branch 'master'.

Fix for bug 306000 - never backtrack a whole page

This fixes bug 306000 by preventing the backtracking to undo the layout of a
whole page, thus starting an infinite loop.
This can be triggered by a page break in the middle of keepWithNext paragraphs.

Comment 17 Bernd Buschinski 2014-09-19 06:28:44 UTC

Hi, thanks for fixing this bug!
This Bug was one of of the main reasons why I couldn’t use calligrawords as my main writing application. Now my big “writing times” are over, but I hope that the test document helped a bit :)
I have more bugreports on bko (with testdocuments), maybe I should re-test them all, as soon as I have time.
Anyway, just wanted to say thank you! You Rock!
