[GNC] Exiting gnucash Lock file Vol 226, Issue 57

[Peter]

Here is the testing methods I used to verify the issue I have noted.

Selected a known small good gnucash data file.
Storage Location: Local D:  c: drive is Samsung SSD and D: is Seagate 2TB
GNUCASH Storage type :  XML and compressed
Operating system: Windows 10
GNUCASH version 4.9
The opening method in ALL test was to use the GNUCASH icon on the 
TASKBAR and then select the recent (test) file
If the LOCK file was not deleted it was removed using the windows File 
Explorer


-----------------------------------------------------------------------------------------------------

Test #1: - change, Save Button and then File->Quit

Result: This was repeated 5 times each time the same result - Lock file 
was deleted and the change was Saved.

-----------------------------------------------------------------------------------------------------

Test #2 - change then File>Quit and save at 15 seconds on timer

Result: In test 5 of 5 Lock file was NOT deleted and the change was NOT 
saved in the data file
This test was actual performed more than 5 times but I did note 5 of 5 
in one contiguous run. There were a few test that asked to save the 
transaction prior to the question of save the file
I was never able to get it to repeat twice in a row.

-----------------------------------------------------------------------------------------------------

Test #3 - change and exit File->Quit wait for the Save dialogue then let 
it time out

Result: In test 5 of 5 Lock file was deleted and the change was saved in 
the data file

-----------------------------------------------------------------------------------------------------

Test #4 - change and wait for autosave then File->Quit

Result: In test 5 of 5 Lock file was deleted and the change was saved in 
the data file

-----------------------------------------------------------------------------------------------------

Test #5 - change and wait for autosave then use X method

Result: In test 5 of 5 Lock file was deleted and the change was saved in 
the data file

-----------------------------------------------------------------------------------------------------

Test #6 - change then use X method wait for the save dialogue and save 
at 15 seconds on timer

Result: In test 5 of 5 Lock file was NOT deleted and the change was NOT 
saved in the data file

-----------------------------------------------------------------------------------------------------

Conclusion:

There is an issue in exiting with the SAVE button enabled/Highlighted 
and complying with the dialogue to SAVE the Data file.
Test#2 and Test#6

Four methods of exiting that do delete the LOCK file and SAVE the latest 
changes
A:    Waiting to exit after an Autosave  then File->Quit
B:    forcing a Save by using the SAVE button then File->Quit
C:    Waiting to exit after an Autosave  then the X method
D:    forcing a Save by using the SAVE button then the X method

  X method works if you do a SAVE using the Save Button or wait till 
after an Autosave then exit via the X method

There is an issue with exiting and relying on gnucash to save the data 
if gnucash produces the dialogue to SAVE the data then File->Quit or the 
X method
The Save does not work and the LOCK file is not deleted.

  I cannot safely say I do not use the X method as I now have doubts 
about it, I may use it or I may not.

Hope this helps someone as now I understand why sometimes it does work 
and does NOT work, there is a bug in it or is it a misinterpreted 
enhancement.
