Calc with 2 sheet tabella and example a screenshot of tabella

Calc crashes when I highlight a few lines as in the attached file; tried it on linux ubuntu12.04 and W7 on different PCs
Comment 1 Julien Nabet 2014-04-03 17:21:17 UTC
On pc Debian x86-64 with master sources updated 2 days ago, I don't reproduce this.
However, memory consumption increases and above all, there's some slowing when selecting the rows.

Markus: even if I can't reproduce the crash, I think it could be an interesting test case (eg: for Valgrind and/or Callgrind), any idea?
Comment 2 Markus Mohrhard 2014-04-03 22:18:04 UTC
Marking it as performance problem.
Comment 3 m.a.riosv 2014-04-03 22:23:05 UTC
I can't reproduce the crash:
Version: Build ID: 3be8cda0bddd8e430d8cda1ebfd581265cca5a0f

What I have found is a high cpu usage while applying the background color to cells, or reselecting the same rows. I's a direct format for about 15360 cells. But no crash.
Comment 4 wendrich 2014-05-22 12:56:32 UTC

Experienced the same behavior:
Highlighting more than 5 to 8 lines using STRG makes LO respondig *VERY, VERY* slow and than nonresponding even to the attempt to close the program.

Environment:  WIN7-ultimate-x64, Intel 2-core T5500@1.77 GHz, 2 GB RAM
File:  32 KB L.O. origin calc file, single sheet, range used: A-AA/1-80 = ca. 2000 cells.

Failure: absolute identical reproduceable

No such prob. with same file in re-installed V.
Comment 5 wendrich 2014-05-22 13:09:28 UTC
This bug makes LO calc component literally unuseable.

((Now, I realized I reported this to the wrong version - (where the search lead me to). Please forgive I don't know ho to transfer))
Comment 6 Joel Madero 2014-06-01 04:14:03 UTC
I can't reproduce at all:

Ubuntu 14.04 x64
LibreOffice release

What do you mean by "highlight a few lines" do you mean just select a few rows? And of what sheet? Does it matter?
Comment 7 Cicciopallo 2014-06-03 08:29:04 UTC
I open calc with new spreadsheet, I highlight/select the first odd 30 rows (for example selecting row 1,3,5,7... etc) and calc crashes/freeze/no-respond; it's happened with version on Ubuntu12.04(64bit kernel 3.5.7, gnome3.4.2, ram 8 Gb, Hd 500Gb, processor intelcore i3 m330) windows7 home premium, windows7 professional and with portable version also.
I've installed these estension also: history master 1.1.0, language tool2.2,ooop-accessories-, ooop-templates-separated-all and unified-all, sun_odf-template-pack.

This bug makes calc unusable and forces me to dowgrade to 4.1.6

Comment 10 Yousuf Philips (jay) (retired) 2014-06-03 18:06:11 UTC
Thanks for the screenshots. Yes i find that LibO 4.2.4, 4.2.6 and 4.3 beta start becoming less responsiveness once i reach the 3rd or 4th odd row and if selecting rows quickly, the cpu jumps high and then the UI becomes unresponsive. Also notice that with the rows being selected, trying to scroll up and down with the mouse wheel or the scroll bar halts the app for ~20s. This doesnt happen in 4.1.6. Tested this on a blank spreadsheet and one filled with data, but couldnt get calc to crash.

Comment 12 Markus Mohrhard 2014-12-14 17:53:44 UTC
Please don't remove whiteboard entries set by developers. That will remove thos bugs from some special lists.
Comment 13 Matthew Francis 2015-01-12 11:32:45 UTC
(Edited the title to reflect the fact that this isn't a crash but a performance issue)

It's not possible to narrow this down definitively to a single commit, as the issue started within a set of commits which were apparently not written to be compiled individually - it's somewhere in the range ac84ffb3c90bb5788608eadf2177f587021daaad..e3b91687590f08438b5a5d4eec72e634b11a8589

Possibly c008dc483f8c6840803983e7e351cec6fdd32070 is the most relevant looking

    Switch to using multi_type_vector for cell storage.
    The old style cell storage is no more.  Currently the code is buildable,
    but crashes during unit test.

Comment 14 Charles 2015-04-17 12:39:44 UTC
Maybe this is the bug I was getting ready to report?

Mine is very simple easy to reproduce... and I think it existed in 4.1. series too...

The problem is extremely evident by doing the following:

1. Open a calc spreadsheet

2. Start selecting DISCONTIGUOUS rows

3. As you select additional rows, pause occasionally to right-click on one of the rows

4. Note that the more discontiguous rows you select, the s-l-o-w-e-r it gets to bring up the context menu.

So - is this the same bug? Or should I go open a new one?

Could someone try to repro this on current master please ? I'm not able to reproduce the issue with the latest.

BTW, the commit bc20c6d0f397c0c1aef6ef7d6f750c2f81af8db6 did some optimization on ScMarkData especially for full row selections. Probably that fixed the problem ?

Yes it seems to have been resolved sometime in the 4.4 cycle.

Wasnt able to reproduce your issue with the latest version of LibreOffice, if you are still able to repo it, file a new bug and then leave a comment here with a link to it.
