persistence file mosquitto.db doesn't update

Asked by daniel

Hi,

I have a problem using Mosquitto. The persistence file mosquitto.db doesn't update.
This is the situation: Mosquitto exits, write the persistence database and the file
"mosquitto.db" is generated in the location defined in the config file (this is correct).
Now, if Mosquitto tries to rewrite the persistence database (for some reason) the console
shows the messages:

- Saving in-memory database to //dir/mosquitto.db
- Error: File exists.

And in the persistence database's folder there are the first file written ("mosquitto.db")
and another db file named "mosquitto.db.new" . Mosquitto then considers always the first (old)
persistence database ("mosquitto.db"). This is incorrect.

Do you have any suggestions?

Thanks.

Hi there,

What OS are you running, and what version of mosquitto? Did you compile mosquitto yourself?

Thanks,

Roger

Hi Roger,

thanks for you quick reply!

OS is a Windows 8.1 pro, while version of mosquitto is the 1.3.2.
I'm using the binary file ("mosquitto-1.3.2-install-win32.exe") downloaded at this link http://mosquitto.org/download/.

Thanks,
Daniel

Looks like Windows has different behaviour for rename() than anybody
else. I'll see about fixing it, thanks.
