Description Hkais 2014-06-23 12:19:30 UTC
Created attachment 101580 [details]
the gdb "bt full" trace

We use Open/Libreoffice since 2006 and we love it! (I had to use MS Word since version 6, so I really love it)

But now I am facing a issue, there I cannot find a workaround.

I have a document, with a lot of changes tracking a lot of comments on authoring and also some images. The doc is 14 pages long.

If I try to insert a heading or sometimes only a text on a specific place in the doc, libreoffice is running into a loop an beginns to count page numbers. I killed it with the doc size of 15.000 pages, since the application was unresponsive.
I created a gdb file, which hopefully will help.

best wishes,

Comment 2 Hkais 2014-07-04 08:13:04 UTC
problem still exists on windows, linux and also on the current version
reverted back to ubuntu managed version of libreoffice
Comment 3 Hkais 2014-07-04 10:53:51 UTC
since I was not sure, I have opened a new bug.
bug #80904 which happens now on the same doc
and maybe it is correlated to bug #47935

Comment 5 Hkais 2014-07-16 08:29:20 UTC
Hello Jay,
see also bug #80904

I cannot provide you the doc with the details right now. How can we workaround the issue? (I could create a dev environment, if it helps, but would need some support on it)

As you see I have managed to provide stacktraces, so I think I could provide also more details on the errors, if someone hepls me.
Comment 6 Yousuf Philips (jay) (retired) 2014-07-16 15:06:55 UTC
Hi Hkais,

Is it possible for you to check earlier versions of libreoffice, which you can open the document with and scramble its contents without it crashing, so that you can provide us with a sample document.

You can find portable of old versions at these links

Original file, wich, If I open in Document writer, go on endless page creation loop

When I open that document in .docx, or I convert it to .odt, the document go to endless page creation.

Thanks for your help on that strange case.

Comment 12 Keith Curtis 2016-03-05 21:16:10 UTC
I can't repro this in LibreOffice 5.1 with the sample file, either by adding headings and typing text, or by saving to ODT.

Can you please try again with the latest version and if it still happens, try to give any more guidance on how to repro?
Comment 13 Yousuf Philips (jay) (retired) 2016-03-06 11:26:16 UTC
So opening attachment 115772 [details] in master and the endless page counting happens without me doing any editing and it reached over 2 thousand pages before i closed the document when the document only has 56 pages and all during that time its eating 80+ percent of my cpu.

In earlier versions, like the OP mentioned, once you start editing the document (i was adding page breaks on radom pages), the endless page counting happens and if it doesnt happen, attempt to go to the last page of the document and you'll see it start then. I can reproduce this in 3.3.0, so its inherited.

Something is majorly broken with this.

Interesting; I can get to the bottom of the document with ctrl-end after load - but clicking into the document there gives me a hang:

I've already seen the bt provided by Michael (see https://bugs.documentfoundation.org/show_bug.cgi?id=80392#c14) in other bugs.
It should be good to list them all and put them in "See also" but, obviously, fixing this tough one may help in quite some bugs.

perf flamegraph

On pc Debian x86-64 with master sources updated yesterday + last reproducer file from Luke, I could reproduce this.

The trace shows the well known layout pb (PrepareMake, MakeAll).
IMHO, fixing layout design may help a lot since it would tackle dozens of bugs.
I don't know if it would need a full redesign of layout management or just some fixes but I suppose that if it hasn't been done yet, it's because it must be very complicated.
Should be one of top priorities anyway.

It seems indeed a dup of it, an image anchored in a header which brings infinite loop in layout => page count increases endlessly.
Any reason to not consider this one as a dup?
Comment 28 Timur 2020-01-28 20:39:10 UTC
No. We can mark it. But it's a pity any of these wasn't resolved.

Comment 29 Timur 2021-06-09 09:36:47 UTC
Fixed in 7.2+. 
LO opens 65 pages and MSO 66 pages (exact differences are not this bug).

Hi Timur,
Please, create a follow-up ticket instead. this issue is already long enough
Comment 32 Timur 2021-07-16 09:44:15 UTC
3-page DOCX still blocks Writer in LO 7.3.
But not if image removed from header. 
I'll just write that in bug 38575.

Dear Hkais,

To make sure we're focusing on the bugs that affect our users today, LibreOffice QA is asking bug reporters and confirmers to retest open, confirmed bugs which have not been touched for over a year.

There have been thousands of bug fixes and commits since anyone checked on this bug report. During that time, it's possible that the bug has been fixed, or the details of the problem have changed. We'd really appreciate your help in getting confirmation that the bug is still present.

If you have time, please do the following:

Test to see if the bug is still present with the latest version of LibreOffice from https://www.libreoffice.org/download/

If the bug is present, please leave a comment that includes the information from Help - About LibreOffice.
If the bug is NOT present, please set the bug's Status field to RESOLVED-WORKSFORME and leave a comment that includes the information from Help - About LibreOffice.

Please DO NOT

Update the version field
Reply via email (please reply directly on the bug tracker)
Set the bug's Status field to RESOLVED - FIXED (this status has a particular meaning that is not 
appropriate in this case)

If you want to do more to help you can test to see if your issue is a REGRESSION. To do so:
1. Download and install oldest version of LibreOffice (usually 3.3 unless your bug pertains to a feature added after 3.3) from https://downloadarchive.documentfoundation.org/libreoffice/old/

2. Test your bug
3. Leave a comment with your results.
4a. If the bug was present with 3.3 - set version to 'inherited from OOo';
4b. If the bug was not present in 3.3 - add 'regression' to keyword

Feel free to come ask questions or to say hello in our QA chat: https://web.libera.chat/?settings=#libreoffice-qa

Thank you for helping us make LibreOffice even better for everyone!

Warm Regards,
QA Team
