New Plugin - cause Action Groups to hang

I am working on a Squeezebox plugin. I have the code reading my Squeezebox settings correctly and dynamically updating a bunch of States created for the Device. My system is hanging, however, when I try to set up a "new" Action Group while the plugin is running. I am not sure why, but I must fore quit Indigo each time to continue. Everything is fine once I disable the plugin. I have gone so far as to remove my Actions.xml file from the plugin, but this did not help.

I am not sure what to do next in terms of debugging. My concurrent loop is as below (not sure this is helpful):

It looks like your loop is both polling all of the Squeezeboxes and updating all of their Indigo states very frequently. The delay between the runs of the loop is only 0.01 seconds. That is going to cause the plugin and IndigoServer to be very busy. I'd suggest updating at most every second or two.

Thanks. I will try to slow it down. I actually did some trial and error work and found that writing the time elapsed was causing the problem. When I took out the lines

Code: Select all

               s.send(SQplayerid+" time ?\r\n")
               data = s.recv(1024)
               data=data.rstrip("\r\n")+" "
               data=self.sqprocess(data,SQplayerid+" time ")
               musicPlayer.updateStateOnServer("elapsed", value=data)


the trouble went away. Then when I changed "musicPlayer.updateStateOnServer("elapsed", value=data)" to "musicPlayer.updateStateOnServer("elapsed", value=round(float(data)))" everything worked again fine. I do think I will slow down the polling however - not necessary.

[matt (support)]

There are some optimizations in Indigo for when a state update is requested (updateStateOnServer) but the new state value is unchanged. So in the original case the value was probably updating a ton -- which then causes the Indigo Server to: check for Device State Change triggers that need to fire, update Control Pages inspecting that state, push the new state changes to all connected Indigo clients. If that is happening several times a second, then there will be issues with connected Indigo clients that are trying to update their UIs to reflect the rapid state changes.

Even though rounding the state value helps prevent the problem, definitely increase the sleep to around 1 second. No reason to be updating it 100 times a second...

Matt

This is the same type of problem with the nest plugin and to a lesser degree with the caddix plugin. My question is there a way to modify the way the action group/trigger works to avoid this. My system appears to work in operating mode with these plugins running and it is only when I want to work with the Indigo client that the problems occur. It just seems to me that with all of the great (but more complicated) plugins, we will see this more and more. I really have no idea what I am asking of you, so if it is an unreasonable request please ignore.

There are some performance issues we are looking into addressing with regards to the client UI making more requests to the plugin than is required (when dialogs are shown). That said, it is best to have the plugin both not spin its wheels doing busy work (polling more often than needed) and not send more requests than are needed to the IndigoServer.

The problem with the Nest/Caddix plugins might be a bit different than the issue on this thread. Those might be blocked waiting for hardware/network requests. Being blocked isn't going to chew up the CPU utilization, but it can cause problems if the Indigo UI is trying to make a request to the plugin. So if a plugin has to make requests that may block for a long time, those should be moved into a secondary python thread in the plugin.

The changes we are making to the Indigo client will help though. But plugins still need to try to behave nicely and minimize CPU usage and be able to respond to Indigo UI requests in a timely manner.

Can not ask for more. Maybe we need an App Store type approval Just kidding. Have been waiting for 20 days for the new Weathersnoop so approval process is a disaster.

[jay (support)]

Just to get a bit more specific: if a plugin does anything that can take significant time (especially Apple events, network connections, or serial communication that blocks, particularly when the target may be offline and therefore might never respond) then the plugin writer needs to safeguard the main plugin thread so that other requests from Indigo to the plugin (mostly for UI which have to go from client->server->plugin process and back) will not block.

I've just gotten into the habit of putting anything I'm talking to like that into a separate thread to avoid this exact problem. Creating/managing threads in Python is pretty easy so there's very little reason not to do it.

Anything happening with a Squeezebox plugin?

Thanks,

Carl

Sorry I saw this over a year late. Yes I have a plugin for Squeezebox. Happy to share it.

Love to try the plugin myself. Will it be posted soon?

Thanks,

Carl

Increased sleep to 2.0 seconds as something in Mavericks caused the Squeezebox plugin to start guzzling CPU. This improved performance for a bot, but after a few hours it returned to 100% CPU usage. Not sure why.

Just tried to install the plugin and got this error:

Code: Select all

Error                           ReloadPlugin() caught exception: FileIOError -- rename/move of file or folder failed -- check file/folder permissions


Edit: Got it...just needed to change the permissions of the file.

Thanks,

Carl

Almost got it. I entered the IP and port, 9000 in my case, and get this error:

Code: Select all

Squeezebox Plugin Error         plugin runConcurrentThread function returned or failed (will attempt again in 10 seconds)

Look at this thread. I think I fixed it. I had same issue on another plugin. Not sure why this is not affecting my machine the same way, but the fix should work.
