Sample file

The attached file is produced (only) with LibreOffice but it can not open it again.

I do not know the reason, but there are some rare settings
- The document size is custom: 148×42 cm (A5×2).
- It has a frame with two columns (= 2. page on the bottom).

I tried to open with LO 6, LO 7.1, LO 7.2, LO 7.3 but all versions are hanging during file open.
Comment 1 m_a_riosv 2022-08-21 11:04:23 UTC
The document is NOT conformant ODF1.3!
Generator: LibreOffice/7.3.5.2$Linux_X86_64 LibreOffice_project/30$Build-2
https://odfvalidator.org/
Do you have a version previous to the issue?

Previous state of the document

This is the previous state of the document. This opens normally with LO any version.
Comment 3 Mike Kaganski 2022-08-21 14:44:26 UTC
Opens fine using Version: 5.0.0.5 (x64)
Build ID: 1b1a90865e348b492231e1c451437d7a15bb262b
Locale: ru-RU (ru_RU)
Comment 4 Rainer Bielefeld Retired 2022-08-21 16:13:42 UTC
Did I miss something? 

Currently I see: LibO hangs when opening damaged document from unknown source.  Reproducible with  Installation of Version: 7.3.3.2 (x64) 
Build ID: d1d0ea68f081ee2800a922cac8f79445e4603348
CPU threads: 12; OS: Windows 10.0 Build 19044; UI render: Skia/Raster; VCL: win
Locale: de-DE (de_DE); UI: de-DE |  Calc: threaded | ElementaryTheme | My normal User Profile. 

But a document saved from Sample " Previous state of the document" with this versions opens without any problems. So the question is: how has Névtelen 1.odt been created? With which version? Do we have a Filesave problem?

Workaround

Rainer, the answers on your questions:

1) "Névtelen 1.odt" is produces with:

Version: 7.3.5.2 / LibreOffice Community
Build ID: 30(Build:2)
CPU threads: 4; OS: Linux 5.15; UI render: default; VCL: gtk3
Locale: hu-HU (hu_HU.UTF-8); UI: hu-HU
Ubuntu package version: 1:7.3.5-0ubuntu0.22.04.1
Calc: threaded

2) This document never seen document processor other the LibreOffice.

3) There is a "Previous state of the document". Steps to reproduce the error manually:
- Open the "Previous state of the document"
- Set page size to 14,8×42 cm.
- Insert a new frame the the first page: 1. width: 14,8 cm, anchor to page, top:  21 cm from entire page 2. borders none + 0,7 cm, columns: 2 with 0,78 cm gap.
- Cat the content form 2. page and insert to newly created frame.
- Save the document.
- Open it. It hangs.

4) And a new information. I experimented and found a workaround: Instead of setting border to 0,7 cm I set Wrap left, right, top, bottom to 0,7 cm and the hanging is gone. Maybe the error will be around the border settings. See the attached "Workaround" file.

The problem is a usual layout loop problem, with regression point in the 5.3 release cycle.

Regression after commit 5d9d0f3c979732ade57b9c4c4960dd030ffdc9f9

    there is a function for that: CalcLineSpace(xx, bEvenIfNoLine)

> The problem is a usual layout loop problem
That would be my assessment too. The commit reference is for bug 41542. Previously LO was ignoring border empty spacing when there was no border line, but now that border spacing will be added, affecting the layout slightly. I'm sure it is irrelevant.

If you enable the border-line, then it will also hang prior to LO 5.3. Removing regression and bisect flags since these aren't layout commits, and weren't the cause of a can-load-and-modify-in-master but can't-round-trip-the-modification.
Comment 9 Justin L 2022-08-22 14:49:08 UTC
Using attachment 181950 [details] from comment 8, it hangs already in LO 3.5. Assuming the layout issue is inherited from OOo.

Confirmed that it also hangs in OOo 3.2.0.
Comment 11 Justin L 2023-05-13 14:21:27 UTC
repro 7.6+ using comment 8's example.

The memory usage is not climbing, just one thread that runs at 100% forever.
Comment 12 Justin L 2024-05-31 14:03:02 UTC
repro 24.8+ (I waited for about a minute)
Comment 13 Bernhard Breinbauer 2024-06-19 06:25:53 UTC
I did some tests with a file, which I'm not able to open:

* LO also hangs on Windows (Version 24.2.3.2 / Portable)

The following test were done on Linux with flatpaks:
* Version 24.2.0.3 and 24.2.2.2 -> works
* Version 24.2.3.2 and 24.2.4.2 -> file will not open, LO hangs

Those are the versions currently available as flatpaks. Maybe someone with Windows can find the specific version with Portable installations...
