With: 60 jpg images - 102 Mb ->no crash

mariosv - do you mind describing the process to get this crash? Sorry not familiar with photo album so explicit steps will help us triage
Comment 2 Samuel Mehrbrodt (allotropia) 2013-05-16 20:14:08 UTC
I reproduced this using Windows 7 64bit when I inserted ~200 Images.
However, on Ubuntu it didn't crash.

@Joel: Just use the Photo Album to insert images (Impress->Insert->Image->Photo Album)

Thanks Samuel - I learn something new about LibreOffice every day

I imagine this is an Out of Memory, so it would be interesting to get a re-test on e.g. a current windows daily build to see if the various graphic cache re-works have had any effect on this

Cannot reproduce using

Build ID: fdc1bd89559ea5efe2b3f6aa45b5158fedaed587
CPU Threads: 8; OS Version: Windows 6.1; UI Render: default; 

Probably solved with the size check for swapped in graphics (0ca0202a0994c0b7c99c366fd5cafd8a655df203). Still, get an endless loop in OLEObjCache which has a timer and seems all the time to check if it should unload someting. Will check if I can reproduce this...
Comment 8 Armin Le Grand 2016-04-26 15:28:24 UTC
Really strange - the office works, but is unresponsive - something consumes 100% of one CPU core...
Comment 9 Armin Le Grand 2016-04-27 10:55:11 UTC
Found out that EditEngines consume the time, their OnlineSpellTimer triggers all the time, never stops. Is a timeout of '1000' intended...? Changed to 10000, solves the problem.
Nonetheless, the app crashes on closing the document (RequestHandler::pGlobal destructor)...
OTOH too many outliners exist, this leads to the trace that currently for each inserted graphic a new DrawModel is created and not destoyed. Found a problem in SdPhotoAlbumDialog::createCaption where a SdrModel is created by using pDoc->AllocModel(), but never freed. Each SdrModel creates 4 SdrOutliners (SdrOutliners: 3 by model, 1 by Sd (mpInternalOutliner)). It is only used to construct a single SfxItemSet to set some attributes at the created CaptionShape. This again will lead to problems since the SfxItemSet/SfxItemPool which is used to hold the items is *not* from the same SdrModel that the SdrObject is in.
I would guess that not 'AllocModel()' was intended, but just getting the SdrModel from the existing document.

Error was added by ommit 070141b854c7731aa44ccf6ce446802ad8653697, 'tdf#64573: Add captions to Photo Album'. This bug also explains why the added caption looks so bad. Trying a solution...
Comment 11 Armin Le Grand 2016-04-27 11:01:08 UTC
BTW: Only happens when creating caoption objects is switched on (default). It is questionable why all is done using UNO API, except creation of the SDrCaptionObj's.
Comment 12 Armin Le Grand 2016-04-27 12:11:03 UTC
Okay, when using pDoc as SdrModel no extra SdrModels get created. Still had a crash, since CreatePresObj was used and the object was added to the slide (pSlide->InsertObject). PresObj's are already added at creation, so it was added double and gets deleted double -> crash.
Both problems are due to unlucky design, people programming have to know too much about PresObjs and SdrModels to use the internal tooling. SdrModel::AllocModel() should not exist, maybe a Clone that would make clear what happens. PresObjs should only be fetchable (GetPresObj is there) and are created on demand dependent of PageLayout, even a CreatePresObj(PRESOBJ_TITLE, ...) may return null if a layout is set that allows no PRESOBJ_TITLE. All bad traps...

Two errors corrected, patch on gerrit.
