Re: [Mosquitto-users] Sending reload signals from java

[saurabh patil]

I am adding and removing some user credentials in password file at run
time. I want mosquitto to reload the configuration file after adding a
particular number of users to the password file. If I understand correctly
reloading mosquitto configuration file will also reload password file.
Please correct me if I am wrong.

I do have PID for the mosquitto but the problem is, on Linux I can use kill
command to send SIGHUP signal to mosquitto but I am not getting any way to
make it on Windows. I want to do this on Windows without restarting
mosquitto.

Thanks,
Saurabh

Re: [Mosquitto-users] Sending reload signals from java

[Sharon Ben Asher]

Hi Saurabh,

I am interested in the same request (for the same purpose - reload the 
configuration and ACL file)
However, I am only interested in Linux so I guess my job is pretty 
straightforward - invoke kill command from Java.
I think there is a real problem on Windows (regardless of mosquitto), since the 
OS itself does not recognize the notion of signals...

Sharon.

Hi All,
Have any one tried sending reload signal to mosquitto process from java.if yes 
kindly share it. thanks in advance.

[Josh Hawley]

Wouldn't the proper way to fix this be to create a way to
programmatically manage users without reloading?

At a high level I guess it should be as simple as: find PID of
mosquitto; send SIGHUP. But I really would like to understand the use
case. Do you have a problem with mosquitto that leads you to
periodically reload the broker?

As you've noted this isn't currently possible on Windows. I've done
some searching but haven't yet found an accepted way of dealing with
the problem.

As Josh points out, this is really best handled without reloading. One
of the possible plans for the future is to have a broker interface to
make this easy to do, even with the simple password/acl files. It is
currently possible to write your own password/acl handler so this may
be the best approach for you. Take a look at the
src/mosquitto_plugin.h file for details of what functions you need to
write. This allows you to integrate the broker with whatever your
preferred method of holding user data is, such as a SQL database.

Cheers,

Roger
