Broker corrupts persistent database mosquitto.db

[codami]

It can be easily reproduced like this:

1. given you have the following config;

persistence true
persistence_file mosquitto.db
persistence_location D:\
log_dest file D:\mosquitto.log
log_type all 

2. start the broker
   mosquitto.exe -c mosquitto.conf

3. start a client with a persistent session that subscribes to SYS topics
   start mosquitto_sub.exe -i Client1 -c -q 2 -t $SYS/broker/# -C 10

4. wait for around 15 seconds

5. stop the broker

6. start the broker again

The broker fails to start with:

1492007506: Error restoring persistent database, message store corrupt.
1492007506: Error: Couldn't open database.

The log file and corrupted db file are here: files.zip

Thanks for the good writeup. I think this has been fixed in the commit I just made. Are you able to test it for yourself?

[codami]

It works fine now, thanks!

Great, it'll be part of the next release. Thanks for feeding back.
