Does not start - ~/.nixnote/nixnote.conf issue

[robert7]

It says "DEBUG ... Another running instance with same account detected - configured action: "SHOW_OTHER"" ... Trying to activate it..

That means the app is already running in your system. And the new instance can't start - and according to configuration it tried to activate the "other instance" and then quit.

I agree that the DEBUG level may not be appropriate, so I change to INFO (but its not really an error).

[robert7]

Btw: --logLevel=0 is TRACE log level (most verbose); DEBUG level is --logLevel=1 and INFO level (default) is --logLevel=2

I will improve logging in the code handling running instances (as I also had problems in special circumstances).

Btw - don't remove keyin the conf file - as you may corrupt the database (if you run 2 instances with same database).

In the last version 2.1.0-beta4l you get a bit more info, whats is happening:

Cheers - this will make it much easier for others to track this down if it ever happens again.

I am pretty sure that I had already killed the other running instances of nixnote2, but from the error messages it does look like I was wrong.

[robert7]

The "instance running" detection is done by shared memory segment. In "normal cases" this should work OK, but for special cases it may not work correctly.

E.g. I have seen one case where 2 instances each compiled again different version of Qt on same machine, didn't do the detection correctly.

In case it happens again, try analyse a bit and eventually send me more info.
