Re: Audacity 3.0.1 RC01 (for testing only)

Not finding the lastlog file is rather interesting by itself.  It should be there.  One of the last things that Audacity does when it exits is dump the log to that file.  The only reason I can think of that it might not be doing that is that Audacity is not ending cleanly.

 

James has come up with an idea on how to resolve the open error, but I’m still going to look into why it’s happening.  It really shouldn’t be.  But, whether I find the real cause or not, we’ll put in James’s solution.

Not able to find the lastlog but I seem to run into the issue pretty frequently just by opening/importing files in multiple windows. Maybe that is the key.

 

Seems to be fairly easy to reproduce on FreeBSD and Windows but it doesn't seem to happen in any particular sequence but it always happens during an open file via ctrl+o type open from what I can tell.

But, what’s interesting about this is that it’s not as simple as I first thought.  If it had been a simple file locking issue, then we could have just increased the number of retries that sqlite performs until the operation succeeds.

 

However, this is not a “plain” file locking issue.  It’s a “database” locking issue where two processes/threads are trying to use the database concurrently.  Almost as if two Audacity’s were running and fiddling with the same aup3.  (I know that’s not the case.)

 

I was able to reproduce the same message by holding an active “write” transaction using the “sqlite3” command line utility.  If I use the same utility to hold a “read” transaction open, then the problem doesn’t happen.  That suggests that something is writing to the database and, since we can probably assume it’s not some other application, it must be Audacity, maybe something in a different thread.

 

Are you able to reproduce it Jack?  Do you remember the exact steps?  No biggie if you can’t since this is already a great help, but if you can, then I’d be interesting to see your “%APPDATA\audacity\lastlog.txt” file after you get the error and close Audacity. (the full log is saved at Audacity exit.)

 

Again, thanks for letting us know.
