When does GnuCash create .log files?

[DaveC49]

To be useful the logfiles should be being written as each transaction is
recorded rather than only at the end of a session. In the latter case if a
crash/programming fault causes Gnucash to exit abnormally the log file would
contain no useful information. Autosave should only be working on the main
data file and not the logfiles.

I have just closed down gnucash at 09:39:54 local time.                                   
date Modified
The logfile is named:        TestBooksBudget.gnucash.20170517093954.log         
Tue 16th May 2017 18:49:11 AEST
The last backup is named:TestBooksBudget.gnucash.20170517093954.gnucash  
Wed 17th May 201709:39:54 AEST
The current file is :          TestBooksBudget.gnucash                                         
Wed 17th may 2017 09:39:54 AEST

The previous logfile:        TestBooksBudget.gnucash.20170516184911.log         
Wed 17th May  2017 09:39:39 AEST
The previous backup:     TestBooksBudget.gnucash.20170516184911.gnucash  
Tue 16th May 2017 18:44:10 AEST.

If I now open Gnucash the backup file remains the same as the above at this
point.
A new log file is opened  TestBooksBudget.gnucash.20170517095417.log         
Wed 17th May 2017 09:54:17 AEST
The previous data file is renamed: 
                                 
TestBooksBudget.gnucash.20170517095918.gnucash    Wed 17th May 2017 09:59:18
AEST. ( the time difference is most likely that required to open and read
the previous data file.

A file TestBooksBudget.gnucash.ffffffffa8c00400.13920.LNK Wed 17th May 2017
09:54:17 AEST is also created when the file is reopened along with the lock
file,  TestBooksBudget.gnucash.LCK Wed 17th May 2017 09:54:17 AEST. Have no
idea yet what the first file does? 

This tends to support the view that the logfile is opened at the start of a
new gnucash session and then transactions are written to it as they occur.   

I have an autosave interval of 5 mins.

A new back up file TestBooksBudget.gnucash.20170517095918.gnucash Wed 17th
May 2017 09:39:54 AEST and a new log file
TestBooksBudget.gnucash.20170517095918.log Wed 17th May 2017 09:59:18 are
created at the end of the autosave interval.

(Gnucash 2.6.16  on Linux Mint 18.1)
