PowerScheduler unconditionally checks every second (1 Viewer)

AW: Re: PowerScheduler unconditionally checks every second

I am inclined to agree.

It might be of interest though to understand why the developer fixed this at 1 second. What would for example be the downside of having 60 sec intervals instead of 1 or 10 sec?

I've no clue. Anyway, the patch below against 1.2.x fixes it for me. I've attached a fixed version of PowerScheduler.dll for MP 1.2.2.

    PowerScheduler: Do not poll at one second intervals
    
    This is a totally unnecessary load on the system

I've no clue. Anyway, the patch below against 1.2.x fixes it for me. I've attached a fixed version of PowerScheduler.dll for MP 1.2.2.

Thanks for the initiative, Oxan!

I renamed my old powerscheduler.dll, saved the new one in the TV_Server plugin directory and then restarted the service (without going through the config though). When I launch MP the homescreen comes up, followed by a message window telling me that the connection with the TV Server was lost. Restoring the original version cures the issue.

Have I done anything wrong?

Regards, HTPC_Sourcer

I tested the attached dll, works ok here.

AW: Re: PowerScheduler unconditionally checks every second

Well, what can I say. My setup reacts with "TVServer connection lost". It's a pity, I would have loved to test a less frequent polling.

 

[JBravo]

Perhaps a stupid question, but did you stop/quit both client(s) and server before replacing the dll? I'm running a multi-seat setup here.

It's a single seat installation and I did restart the TV Server after replacing the dll. As far as I remember I din't stop it before but Windows did not complain when I renamed the file.

Anyway, I'll give it another try and report back.

Update: alright, this time I stopped the TV server prior to renaming the old dll. It works.

Tank you your server patch works perfectly

is this necessary to send keep server alive every second also for the client?

The message above is sent every 25s, this to inform the TV server that there are active clients. I think this was done in the "normal" loop for the PS Client Plugin.

ok thank you
