Download and is server occupied

[ustk]

@d-healey

Server.setServerCallback(function(isOccupied)
{
    // Triggered with server calls but not with downloadFile
});

It's not a big deal because I could do what I wanted in the downloadFile function, but it would have been more straight forward to have the server CB to trigger

@ustk What is isOccupied?

[ustk]

@d-healey

isOccupied is true when a call is made and the server is waiting for the response

[oskarsh]

You can create a isOccupied whenever you start a download, when you finish the download you clear that state. That is how loading is usually done. Getting the exact loading state is sometimes tricky thats why you often see a fake progress bar that seems to hold the 99% after some time while waiting for the download to finish.

If you want to display the stuff that is currently loading you can use:

https://docs.hise.audio/scripting/scripting-api/server/index.html#getpendingcalls

and

https://docs.hise.audio/scripting/scripting-api/server/index.html#getpendingdownloads

@oskarsh yeah that's what I said I did it by tracking inside the downloadFile function, it just would have been nice to have the info in the server CB... But I made my own variable successfully

getPendingDownload doesn't help much, it's an empty array (which is probably a bug) where you can just get its length as information, but it's not useful once you enter the this.data.success case for instance. WAS NON-SENSE

[ustk]

@oskarsh Thanks ! In the end it was easier to use getPendingDownloads().length than tracking the number of downloads manually...
(even if getPendingDownloads() contains nothing, @Christoph-Hart ?)

Still, triggering the server CB would have fixed another issue for me so the request stays relevant

[oskarsh]

@ustk I believe the getPendingDownload is not empty as you can prove by getting its length. Sometimes HISE cannot print out the content of a complex object such as a Download object or a Path for example.

You can loop over that array and get the status of each element.

so basically

for (download in Server.getPendingDownloads() {
    Console.print(download.isRunning());
}

code is untested

I use a broadcaster to track if currently downloading

[ustk]

@oskarsh Of course, stupid me... I tried to trace the content but the download object are access through the specific methods...

[David Healey]

@ustk

This is where I set up the broadcaster - https://codeberg.org/LibreWave/Rhapsody/src/branch/main/Scripts/App.js#L39

Then when I start some downloads I set the state - https://codeberg.org/LibreWave/Rhapsody/src/branch/main/Scripts/Downloader.js#L52

Then after all downloads complete I reset it - https://codeberg.org/LibreWave/Rhapsody/src/branch/main/Scripts/Downloader.js#L191

[ustk]

@d-healey I wanted to ask (because I haven't found anything about a broadcaster connected to a download or server task) but you were faster! Nice but the 3 links you kindly posted are the same...

[David Healey]

@ustk Oh that's weird. I'll update the post, one moment
