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.
