Dear Telesto,

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

Bibisected on Linux with 43all to range
https://cgit.freedesktop.org/libreoffice/core/log/?qt=range=34847f1cf7538c333e9b8700eb4012ae358644a6...d4779887636fa9ab5b477f3436bcd3728a3e30ba

I noticed there were levels of worsening (I marked all as bad).

--- Comment #6 from Telesto  ---
Created attachment 134550
  --> https://bugs.documentfoundation.org/attachment.cgi?id=134550=edit
Example file

Another example for the memory bump, without the interference of undo data
1. Open Calc
2. Set Undo steps to zero (0) ->  Options - LibO - Advanced - Expert config:
org.openoffice.Office.Common/Undo
3. Open the attached file
4. Open the task manager and to monitor for memory usage 
5. Right click a sheet at the bottom and select "Select All"
6. Deselect 1 sheet with CTRL + click (on a sheet)
7. Select delete the selected sheets - Menu -> Sheet -> Delete sheet
8. The memory usage will increase from 483 mb with 250 mb to 733 mb at the
start of the deletion process. Dropping slowly while deleting. After deleting
all sheets except one around 250 mb is used. 

It's still using 200 mb after closing the calc document (returning to Start
Center) where I would expect 110 mb or so (which is used after fresh start of
Calc).

--- Comment #5 from Telesto  ---
(In reply to Buovjaga from comment #4)
Same conclusion as with you description in bug 108617#c2. It's definitely
related to the undo. The default value for "Steps" is 100. Set it to 0 and the
memory growth is hitting a wall.

You can test it by opening Tools
- Options - LibO - Advanced - Expert config: org.openoffice.Office.Common/Undo

Seems the undo data is created for all sheets, when making a change to one
sheet.
