Processing this large sheet on Windows is no faster, also gets held up with "adapt row height" processing.

Noticeable difference in handling between recent master/6.3.0alpha0+ and the 6.2.2.1 release build

Comment 6 V Stuart Foote 2019-03-16 16:16:27 UTC
So, if I force sheet to not update row heights--it loads immediately after calculating formula values.

A work around, but done by:

1. opening sheet

2. cursor focus into a cell with default row height (I used the first cell under the Indexing tables column)

3. select All cells

4. apply format from main menu Format -> Rows -> Height (the value shows 0.21 ")

5. save to a new ODS file

Open the newly saved version.  Seems the SC doc shell then does not call the SetOptimalHeight() or SetOptimalHeightOnly(), and so the document opens to screen with no delay after "calculating" of cell formulas completes. Speed is restored, but lose "optimal" font resize to fit results.

Comment 8 V Stuart Foote 2019-05-01 14:18:44 UTC
So does fix for bug 62268 need revisit? 

Seems if all rows with cells are assigned the "style:use-optimal-row-height='true'" we're doing the correct thing of parsing each row before rendering.

Isn't issue then that all rows of a close to empty sheet receive that style as default? It sets them to default, but parses each for cell content--expensive.

Simple fix might be to change default row style to "style:use-optimal-row-height='false'"--and only explicitly set it for rows with cell content?

Comment 12 V Stuart Foote 2019-11-15 18:57:42 UTC
@Eike, Kohei -- do you have any thoughts for use of "style:use-optimal-row-height='true'" so it would not be as expensive as it is now?
Comment 13 Mike Kaganski 2020-01-19 12:45:23 UTC
The recalculation of heights effectively performs full recalc (so it takes the same time Ctrl+Shift+F9 take). This makes cached values in own format useless.
Comment 14 Thorsten Behrens (allotropia) 2020-02-16 13:22:44 UTC
I believe the underlying problem is that Calc would somehow assign style:use-optimal-row-height='true' to all & sundry. I *think* we had that fixed at some stage, at least cannot repro with some simple documents anymore in 6.4.

Any second thoughts on that? If the above is *still* an issue (perhaps with a more complex setup), I'd love to hear.

Comment 23 Vasily Melenchuk (CIB) 2020-07-24 08:26:21 UTC
In given document we have tons of rows with style:use-optimal-row-height="true" and these rows should be recalculated to find this optimal height. Once I remove this style from rows document begin to load in acceptable time. So feature works okay from technical point of view.

At the same time attempts to set optimal height from UI also very slow. Maybe it requires some profiling & optimization.

While this is quite often case (this value is set by default in many cases) it makes sense to adjust adaptation of row height on load further. Out of my head I see several options:
* provide per document setting enabling or disabling this feature. With disabled by default we will receive less such problems like current one.
* do not calculate on load rows with style:use-optimal-row-height="true" and provided row height. Such scenario should be okay for at least one of original tdf#62268 bugdocs.

IMHO row recalculation on load is quite handy only for generated by third-party tools documents. For documents created in Calc it senseless: given height is correct one (otherwise it is a bug). So for generated docs users should just omit style:row-height parameter to force LO to calculate this row height on load.
Comment 24 François 2020-07-30 12:35:43 UTC
It's even worse here.

I have a document with just a few rows set to "style:use-optimal-row-height='true'" and LO refuses to open the document. It simply crashes.

We are running under macOS 10.14.6 and 10.15.6 and we can confirm that it happens with any version of LO > 6.1.6.3

Hope you get this fixed very soon :)

Please let me know if I can help somehow.
Comment 25 François 2020-07-30 16:09:22 UTC
Quick follow-up :

I've done some more testings all this afternoon.
After messing a bit with the file with LO 6.1, I finally managed to remove some lines where `style:use-optimal-row-height="true"` was applied...

Which led me to being able to open the file with the latest LO (6.4.4.2) - hurray !
Unfortunately, it's then impossible to save the file : LO crashes (no report, no log :-/ ).

Is it recalculating the rows height when saving ? (or do I have to look somewhere else ?)
Comment 26 PremPa 2020-08-08 15:08:29 UTC
I'm not able to find which lines have `style:use-optimal-row-height="true"` 

But I think it's more "friendly", especially for low profile users, to add the possibilty to switch that off by some option.

Just my two cents.

Comment 32 Thorsten Behrens (allotropia) 2021-07-30 15:15:31 UTC
Does anybody have any pointers on the history why Calc sets this use-optimal-row-height="true"' for all rows in a new document?

FWIW, multi-line Calc cells are one possible reason. Create one, type some text so you get e.g. 3 lines (enable Alignment -> Wrap text automatically) - then change zoom value & see the text line breaking change randomly.

How is a Calc user supposed to generate a document with a row-height that exactly matches the needed area, if the row height is not adapted on load then?

Nope, and seems unnecessary/non-performant to have it applied to all rows with the style during load.

Mixing apples and oranges? Not so sure as the scale on zoom is clean if you enable the Calc general option 'Use printer metrics for text formatting'. Otherwise the recalculate 

While the tweak done for bug 62268 ( https://gerrit.libreoffice.org/c/core/+/52521/ ) to always process use-optimal-row-height="true" on load is causing the annoyance of slow opening.

Wouldn't Kevin's test ( as on https://bugs.documentfoundation.org/show_bug.cgi?id=62268#c38 ) be a reasonable adjustment to correct this?

does not hold the cell content at scale when zooming in or out, and hides or shifts it.

(In reply to Thorsten Behrens (allotropia) from comment #32)

See 
https://bugs.documentfoundation.org/show_bug.cgi?id=62268#c46

In short: by default each row has style:use-optimal-row-height='true'. When you type multiline content in a cell and hit enter, then style:row-height is updated. For style:use-optimal-row-height='false' when you type multiline content the style:row-height is not updated, so that it uses default row height or the old value. In both cases on FILEOPEN the correct style:row-height is used directly, no need to recalculate.
Comment 36 Eike Rathke 2021-08-06 18:39:18 UTC
I didn't wrap my head around, neither any possibly underlying problems nor the proposed solution, but the procedure described in https://bugs.documentfoundation.org/show_bug.cgi?id=62268#c12 and mentioned again in https://bugs.documentfoundation.org/show_bug.cgi?id=62268#c47 sounds reasonable to me on first sight.

Citing here for completeness:

a) if there is no height attribute and the "use_optimal-row-height" attribute is set then calculate the row height

b) if there is no height attribute and the "use_optimal-row-height" attribute is not set then use the default value

c) if there is a height attribute just use it

> This is not a regression, see comment 15

This *is* a regression.
In comment 15, you point to the fact that *forced recalculation* takes just as much. But that is not the issue raised here; the low performance of the recalculation itself is a separate issue. Yes, *if* that separate issue were fixed, and recalc took an instant, this issue would *possibly* be also resolved (unless there is another reason to restore cached height even if recalc doesn't take long). But this specific issue is about the problem that had appeared after the commit identified in comment 7, and is specifically about the new behavior of ignoring the cached values, and taking that long time, where it *did not* previously: on file open.

Comment 49 Vasily Melenchuk (CIB) 2022-02-01 17:46:54 UTC
A proposal for resolving this problem is in gerrit https://gerrit.libreoffice.org/c/core/+/129300

Overall idea is to introduce new document level setting for triggering row height recalculation on load. By default it is off.

But it can be important for generated documents, like in original tdf#62268. In this case document generator could set this flag to have prettier generated spreadsheets.

All other documents (without proposed document setting) will be loaded without recalculation, like before fixing tdf#62268.

Any feedback is welcome.

I can confirm that it takes ages to open, stuck at the "Adapt row height" stage, in LO 7.3.1 on Ubuntu 18.04. I gave up after waiting for 5 minutes.

developers are in  discussion around patch in comment 49

Otherwise bypassing the current "feature" of optimal row heights on a calc sheet is trivial. Need only open the ODS zip archive and change one style string in the comntent.xml

Toggle the style stanza 'use-optimal-row-height="true"' to a value "false", and save it back into the zip archive.

Document will then open in seconds.

Two ways. And this is for existing ODF spreadsheets. But work on a copy (just to be safe). One if you have the file open in Calc, see comment 6.

The other is if you don't want the delay. Simply open archive with Z-zip, notice the content.xml that is the meat of the document. Select and use 7-zip's Edit (configure 7-zip to use vi, or gvim for editing in advance). Find the string "optimal" (in vi, gvim issue the ex / to find). Cursor to the "true" and replace with "false". Write and quit the edit.  7-zip will detect the change and ask if you want to merge back into the archive.

As to making it permanent, not certain but Tools -> Options -> Advanced -> Open Expert Configuration and search for "optimal". 

Adjust the org.openoffice.Office.UI.CalcCommands stanza:

org.openoffice.Office.UI.Commands:LabelType['uno:SetOptimalRowHeight'] Properties long "1" --> "0"

That should keep future sheets from including the optimal set optimal row height style.
Comment 56 pharmankur 2022-03-13 16:52:53 UTC
Thanks for the quick reply !

But it's not working for me somehow.
Content.xml itself was about 45 MB
While opening it was running for more than 30 min consuming 100% of my one processor core. At the end I had to kill it.
  
I tried changing org.openoffice.Office.UI.Commands:LabelType['uno:SetOptimalRowHeight

But it also did not work for any of my existing documents.
Comment 57 kiriup 2022-03-29 15:58:58 UTC
Hi i hope i am posting in the right place. 
I have the same problem with adapt row height taking too long (over 30 minutes sometimes). I have 2 ods files with around 20000 rows and i use index match arrays to get data from one to the other.

I did the actions shown in Comment 55 for both my files and that helped: i can save and open them within reasonable time.

My problem is when i try to add a new column to fetch new data with index match the "adapt row height" appears again and takes forever. To clarify they way i do it is i enter my formula in the first cell of the column that i want to edit and then i copy paste that cell to the rest of the column. The more columns i add this way the longer it takes each time.

I there a way to avoid adapting row height while adding new formulas to columns (not only when opening and saving)?
