Description Kieran Grant 2012-05-07 21:19:24 UTC
Created attachment 61198 [details]
Screenshot of corrupted Presentation Document

Using LibreOffice Build ID: 350m1(Build:202) in Impress on Ubuntu 12.04 LTS.

If I press F7 or use the menus to open Spell check it scans (without picking up any errors, but that is another matter, probably because it needs English Australia).

Then it states it has scanned to the end of the document and whether you want to scan from the beginning, if you say 'No' all is good, but 'Yes' results in the entire document being replaced with some random document. Undo does nothing, had to close and re-open to fall-back to my last save.

Went from ~ 50 slides to 2. (As in attachment)

Screenshot of Impress before choosing an option at search prompt.

When the prompt 'LibreOffice Impress has searched to the end of the presentation. Do you want to continue at the beginning?' the screen behind it gets replaced with an unusual empty template.

This screen disappears if I click 'No' but the entire document gets replaced if I click 'Yes'.
Comment 2 Kieran Grant 2012-05-08 01:40:30 UTC
Amendment: This appears to be a bug in the 'Find' function, as the corruption occurs even when doing normal searches for text.

I don't believe this to be a problem with the spell check function itself.
Comment 3 Kieran Grant 2012-05-08 02:26:11 UTC
BUG Still exists in LibreOffice 3.5.3 (Using latest version from libreoffice.org)

Build ID: 235ab8a-3802056-4a8fed3-2d66ea8-e241b8

BUG still effects 'Ctrl+F' if you search for something and if you don't find it in the document and it then asks to search from the beginning. If it finds it before the end the bug is prevented.

If you search from the start of the document the first time, the prompt asking you whether you want to search from the beginning won't show and thus the bug can be avoided.
Comment 4 Kieran Grant 2012-05-31 15:00:42 UTC
UPDATE: Bug still exists in LibreOffice 3.5.4 Public Release

Build ID: 165a79a-7059095-e13bb37-fef39a4-9503d18
Exists in LibreOffice Impress's Find Functionality.

Problem description (clarification for later):

In Impress If you search for a string of text (not from the first slide) and it does NOT find it until the end of the document it will then ask you if you want to search from the start of the presentation.

At this prompt the visible slide is replaced with a template, if you do not search from the start, the presentation will be restored as it was, no corruption.

If you do search from the start, and it does NOT find the string there as well, the presentation will be replaced with a template.

This bug has appeared in all generic (from libreoffice.org) versions that I have used since LibreOffice Build ID: 350m1(Build:202)
Comment 5 pjacquod 2012-06-17 10:59:57 UTC
For the record, I have started to try to find it out. 
I was able to reproduce it on master.

my current status: the problem should be within the function 

void Outliner::ProvideNextTextObject (void) line 979 in sd/source/ui/view/Outliner.cxx

or below (I mean a function that is called from this one). Since this is the first step where the search or the control spelling are calling this program.
Comment 6 Joel Madero 2012-06-17 18:30:44 UTC
Marking as NEW as it's confirmed, also raising to HIGHEST for importance as this affects too many people and results in data loss. I'm also going to go ahead and put this on the most annoying bugs list. Thanks for posting
Comment 7 Rainer Bielefeld Retired 2012-06-17 22:44:46 UTC
<https://wiki.documentfoundation.org/QA-FAQ#How_to_select_correct_Bug_Status> for status NEW

[Reproducible] with "LibreOffice German UI/Locale [Build-ID: 281b639-6baa1d3-ef66a77-d866f25-f36d45f] on German WIN7 Home Premium (64bit)  

My Test:
1. download open presentation from <https://wiki.documentfoundation.org/images/c/c3/Finding_out_whats_going_on.odp>
   > First slide is visible in Normal View
2. <control+f> for find, String "Michaelsen", 'down icon' until end of document
   > As expected search starts from beginning, no document damages.
3. Redo 'down icon' and 'Restart from Beginning' until you see something looking
   like a template for an enumeration list with bullets and message "redo from
4. Click "No"
   Expected: search simply stops
   Actual: Many slides deleted, remaining ones with template contents

Same problem with "Find and Replace"

Still [Reproducible] with Master " 3.7.0alpha0+  – WIN7 Home Premium (64bit) ENGLISH UI [Build ID: 5af60dc]" (tinderbox: Win-x86@6-fast, pull time 2012-06-14 22:09:53)

Already a problem with 3.5.0 release

[Reproducible] with Server installation of MSVC Master "LibO-dev 3.5.0 – WIN7 Home Premium (64bit) ENGLISH UI [Build ID:  2d0998f-090bcba-45cf606]" Win-x86@6 - 2011-12-01_08.37.54) (here also Spell check problem reproducible

No Problem:

Can you help? Bibisecting might help to narrow down appearance of problem some better.

@ jmadero@usa.com:
Just a hint, no offence: If you want to nominate a bug as "LibreOffice 3.5 most important bug", i.e. add it to bug 37361, please insert "37361" into the "Blocks" field here (not into the "Depends on" field).
Comment 9 Joel Madero 2012-06-18 07:08:55 UTC
My apologies. I actually asked in the IRC channels and I was told to put in depends on. I checked a couple of the other most annoying bugs and they had it in depends on not in blocks....

        dont mindlessly touch the icc-header file on every build
        - this little gremlin touches the header file everytime it is run
        - as icc is very low level, this causes a lot of pointless rebuild
        - everything from vcl up gets relinked
        - this slows every empty 'make build' down by more than 40 percent
        - would really need to check if the file changed before writing, but as we
          rarely change icc itself, I didnt bother with that

Comment 11 pjacquod 2012-06-20 11:32:19 UTC
thanks for the bibisect. 

Just for the futur: the text of the first bad commit is not so imporant. Very important are the last good and the first bad, so in this case: 

first bad: 
# bad: [ed3f955f538bad00cdac118df31daaacf098f9e1]

last good:
# good: [db3589a1e013d6095c1ce486b705dd9ee685b308]

so this gives exactly the interval where to look (there are several commit in between)

slidesorter1: #i116014# Outliner holds ViewShell as weak_ptr.

is my better suspect now. I go ahead with investigation. Info soon.
Comment 12 Radek Doulik 2012-06-22 01:45:28 UTC
I have looked at the problem at it looks like spell checking just goes thru all the slides and switches to the master slide view. Which is confusing and look's like the slides were deleted. They were not, we just ended in unexpected view - master slides view. (I think Florian in comment 10 found it too, but I wasn't sure from the formulation)
Comment 13 Rainer Bielefeld Retired 2012-06-22 03:23:02 UTC
You are absolutely right - where have I had my eyes?!
That's still annoying and worrying, but definitively not critical.
Comment 14 Radek Doulik 2012-06-22 04:48:22 UTC
Commit bdfbbb33a491f3ce34375de14ba33436b04
slidesorter1: #i116014# Outliner holds ViewShell as weak_ptr.

indeed introduces this problem/regression.

pjacquod@gmx.ch, do you want to work on it, or should I try fix it?
Comment 15 pjacquod 2012-06-23 03:03:25 UTC

Here some extract of mails in lib-dev list, between me and Thorsten:

* goal of this patch and the fact it is the suspect:Answer from Thorsten:

well the goal was to decouple live cycles of Outliner and ViewShell
- sadly the change mixes a lot of reformatting with that fix. Hard
to tell if that is now causing some ripple effects. :/

Later I wrote:
I locally reverted
I can confirm this is the origin of the problem. 
I also have to say honestly that fixing this patch is beyond my knowledge of LibO code in this area. So if you say OK, I will push my revert to master. This is not the most polite way of fixing it. destroying your correction, but the one that fit to my knowledge there.

Or have you time to investigate it and fix it ? Sorry, this sounds not very constructive, but in this period I do not have a lot of free time, so I can not offer more.

So if you have time / knowledge to do it, it would be the best. Else reverting it would destroy the change mentioned above. But I think for users, this is less problematic than the current status.

Your input?
Comment 16 Radek Doulik 2012-06-28 01:53:43 UTC
I have pushed fix to master http://cgit.freedesktop.org/libreoffice/core/commit/?id=ca644612762921e772ca95d5e8737325d9f343d2

It changes the behavior of spell/find to remember only the starting position.

I have also tried hard to find the difference the

"Commit bdfbbb33a491f3ce34375de14ba33436b04
slidesorter1: #i116014# Outliner holds ViewShell as weak_ptr."

introduced. The change happens deep inside the


call. It goes down to

void DrawViewShell::ReadFrameViewData(FrameView* pView)

where master page edit mode is used

B+>│311         EditMode eNewEditMode = pView->GetViewShEditMode(mePageKind);                                                                                                         │
   │312         sal_Bool bNewLayerMode = pView->IsLayerMode();                                                                                                                        │
   │313         ChangeEditMode(eNewEditMode, bNewLayerMode);

It comes from meStandardEditMode, which I wasn't able to find out why it was set differently compared to the time before the bisected commit.

So I guess it might be either result of syncing the asynchronous events differently or some change we missed in the problematic commit.

After I changed the behavior with my fix, it works as expected, at least I hope so. Hopefully it will not introduce other regressions.
