Description John A. Paravantis 2017-08-07 06:48:42 UTC
Description:
AutoCalculate stops working when a new column is inserted in a LibreOffice 5.3.0.2 x64 (Windows 10)! To re-enable AutoCalculate, one must close and reopen the document.

To confirm that it is a bug, this issue was discussed at

https://ask.libreoffice.org/en/question/120044/autocalculate-stops-working-when-column-is-inserted/

and it has been confirmed to occur in version: 5.3.1.2, Build ID: 1:5.3.1-0ubuntu2 as well.

Steps to Reproduce:
1. Start a new spreadsheet and confirm that AutoCalculate is enabled.
2. Type in a number in cell A1.
3. Type in another number in Cell B1.
4. In cell C1 insert the formula `=A1+B1`.
5. Confirm that the sum in C1 works correctly; try changing the values in A1 and B1 to verify that is recalculates correctly.
6. Now select column C and insert an empty column to its left, i.e. between B and C.
7. Edit the sum formula (which is now located) in cell D1 to `=A1+B1+C1`.
8. Now type in a number in cell C1.
9. Confirm that the sum in cell D1 is not updated correctly, despite the fact that AutoCalculate is enabled. Hard recalculation works.
10. Close and reopen the spreadsheet.
11. Finally, confirm that recalculate works correctly at all times, now that the spreadsheet was reopened.

The bug has been confirmed by other users, the same behavior was observed for `=$A$1+$B$1+$C$1` on a version 5.3.1.2 (Build ID: 1:5.3.1-0ubuntu2) system.

Actual Results:  
As described above, it was confirmed that AutoCalculate stops working when a new column is inserted, until the spreadsheet is closed and reopened.

Expected Results:
When AutoCalculate is enabled, (1) automatic recalculation should occur continuously; also, (2) there should be no difference in behavior before and after closing and reopening a spreadsheet.


Reproducible: Always

User Profile Reset: No

Comment 4 prossin 2017-10-07 14:05:08 UTC
This is a VERY ANNOYING bug. I suggest to change importance to critical. I see this same bug in every update for years.
This HUGE BUG becomes more relevant because if you save a document in native ods format with inconsistent values in some cells, as described in the procedure, recalc does not trigger on loading.

Please don't modify issue fields unless you understand their meaning. That requires at least trying to read their names carefully (e.g., the Version field has "earliest affected" clarification right below for a reason).

You couldn't have this same bug for years, because it was introduced in 5.3, which was released in the beginning of this year. Yes, it is rather important, but it doesn't qualify for critical - the importance categories have the project's established meanings, not necessarily what natural language implies.

I raise the importance, though, because this is a regression.

I apologize for the mistakes you pointed me out. You're right, this is a fairly new bug but very often I have problems because recalc does not trigger on loading. If something goes wrong with editing (and strange things could happens also with older versions, believe me) when I open a document I cannot be 100% sure that formulas are calculated correctly. So I don't trust LibreOffice Calc anymore from this point of view. It's a pity!

Investigating.
Comment 9 Eike Rathke 2017-11-02 11:57:49 UTC
Minimal reproducer:
* A1: 1
* B1: =A1
* insert column left of B
* edit formula cell of then C1 to =A1+1
* change value in A1 => no recalc in C1

Does not occur if before inserting the column there's a formula cell in column C (i.e. the column right to the one of which the formula cell is edited).

Version 5.4.3.2 works fine, too.

The only problem I see is that if I open a document .ods with auto recalc 'broken' because saved with a previous 'buggy' version, the loading of the file does not trigger recalc. IMHO, the problem is mostly not related to this bug, but to the lack of the option 'recalc on loading' (not an option for ods created by LibreOffice).

You can always do a manual hard recalc (Shift+Ctrl+F9) of the entire document if you suspect you encountered a faulty saved document.

hi @all, 

would you mind recheck script below and reopen this bug, 

or shall i file a new one? 

issue: if you construct the conditions a little more complex autocalculation is blocked again, 

'little stressscript for / against autocalculate problems with shared formulae, 
A1: '2'
B1: '3'
C1: '=SUM(A1:B1)'
copy A1:C1
paste to A1:C10
B:B sheet - insert - column - before
B3:B8 delete cells shift left
D:D sheet - insert - column - before
C2: delete content
E2: watch unchanged and wrong '5'
ctrl-shift-F9: problem recalculated '2'

i think we / you need a somewhat more fundamental solution for theese issues than just patching the occurences shown up so far ... ??? 

most recent version tested, still buggy, older versions fail too:

6_5_0_0_a1_autocalc_error_2, macro to check

hello @BogdanB, 

first: thanks for your help, it's not confirming the bug but narrowing the space he can survive, 

estimating from my tests, the results of you and those of m.a.riosv in https://bugs.documentfoundation.org/show_bug.cgi?id=129255#c1, another machine with linux here also failing, and a friend with a 4-core CPU also failing ... 

there's hardly more than three possibilities: 

1) the fault is dependent on a complex network of basis, versions and settings, thus appearing in some situations while not in very similar, 

2) our systems here are pested with a very special 'turn-off-autocalculate-in-rare-cases' virus which didn't make it to you, i see no sense in such a virus thus i doubt it's written, 

3) you did something 'special' when keying in the script to test? 

1) would say 'much work', 2) i don't believe in, 3) i'd like to rule out. 

i kindly ask for your help, the attached file has a macro which does only key in the values and formulas as i did it for my tests. can you please - have a look inside that it wouldn't harm your system (it's only cursor movements, put 2 in A1 and so on, until deleting C2) and then let it run, and provide a screenshot of the result. 

many thanks in advance ...

Please be sure to have: Data - Calculate - Autocalculate checked.
Comment 27 BogdanB 2019-12-10 20:24:01 UTC
One thing you could do it is to have a clean profile:
Help - Restart in Safe Mode - Restart - Reset to factory settings - and check that 2 boxes: Reset settings and Reset entire user profile.

And I hope that with a new user profile and Autocalculate activated everything is now ok.

@BogdanB c#26, c#27

hello, 

yes, i did that and checked it multiple times, even complete system cleanup and deleting everything than a plaintext copy of my macros and keyboard customization, installed different versions of LO stable, beta and dev versions ... 

even switching my 'locale' to en, es, ro, 

no chance, all tests failed, 

i was already nearly desperate to be the only idiot who should have such errors, but there are other testers who see problems with similar tasks, e.g. 
https://bugs.documentfoundation.org/show_bug.cgi?id=129333#c1 and 
https://bugs.documentfoundation.org/show_bug.cgi?id=129199#c0 

thus i am convinced that autocalculate is still flawed, and it is difficult to work out the special circumstances in which the flaw shows up, 

probably extremely difficult because many aspects of a fundamental error are obscured by interim patches, and so both: 
- in most situations do not occur, and 
- a correction of the fundamental error may produce erroneous results caused by the patches 

... but these are only assumptions ...

Can you PLEASE submit a new bug for the new findings and attach a simple reproducer and step by step instructions, instead of commenting on an old fixed bug? And please try to be concise and not too verbose, remember that someone willing to fix things will have to read it and prose and assumptions are just not helpful.
Thank you.

@Eike Rathke

I think that b. on comment 21, 25 and 28 has been quite accurate and tried to explain all he did in order to help finding and correcting the bug. Contribute of anyone is always valuable and should never be discouraged. IMHO!

Anyway, nothing's new... it is almost the same bug as 2 years ago!
I found a shorter reproducer:

A1: '2'
B1: '=SUM(A1:A1)'
copy A1:B1
paste A2:B2
B:B sheet - insert - column - before

Now recalculate is stuck and LibreOffice does not recalculate B1/B2 anymore!
It is curious to note that if you edit a formula doing nothing (keeping it exactly as it is) recalculate does return to work again for all the cells.

I think that column add/remove feature is a mess, I saw the C++ code and it does not appear as a well written code so when something is fixed some other new bugs come to life.

Seems no one is taking me serious. I now create bug 129396 for this.
Please refrain from posting assumptions and accusations. Thank you.

If you are able to judge that we are eagerly awaiting your fixes.

I overlooked in the jungle of prose comments that meanwhile bug 129333 was created.

Note for the future: Next time you find a bug, please fill a new report as Eike mentioned in comment 29.
There's no point in commenting a bug that was fixed 2 years ago, even if both bugs are similar.

I am not judging anything and I really appreciate all the hard work you do on this project. Sorry if I was rude, that was not my intent, believe me!
I think that what drive many users (me too) to be so critic about these auto recalc flaws is the fact that even the basic user must rely on calculations of a tool born to make calcs. Of course bugs can occur but in this case the user have no chance to understand what happens. I would greatly prefer a crash instead of getting wrong results, don't you? These are my proposals (I know this is the wrong place, I will put them later in the right one):

1) Rise the priority of bugs that can lead to wrong calculations since its a "broken core functionality" 
2) Try to inform the user that the cell calculation will not be triggered by any event. (not easy... I have no ideas)
3)  Add an option that forces a complete sheet recalc in case any cell changes its content. (I noticed that I can always rely on results by forcing a full recalc)

I really appreciate any opinion!

@prossin: thumbs up! polite writing would work better but regarding 'the issue' you are absolutely right

@all: it's a 'bug-field' undermining the thrustworthiness of the program since years (5 as of now?) and not yet fixed, see: https://bugs.documentfoundation.org/show_bug.cgi?id=129541
