Got error after a while #13

Closed chookapp closed 3 years ago

chookapp commented 5 years ago

The extension works fine, but then, after a while (I don't know exactly what I did, if at all) it just disappears from the bar.

I looked for an error in "journalctl /usr/bin/gnome-shell":

I'm using Ubuntu 18.04 GNOME 3.28.2 and version 8 of "printers".

Thank you for your report. I'd like to have some confirmation of the bug, but I'll try to change some async calls (that's one culprit of "too many open files").

linux-man commented 5 years ago

Hello again. Can you edit the extension? It's at ~/.local/share/gnome-shell/extensions/printers@linux-man.org I'd like you to modify the code and see if anything changes in the long run...

At extension.js, would you change function spawn_async around line 25 to

function spawn_async(args, callback) {
    let [success, pid, in_fd, out_fd, err_fd] = GLib.spawn_async_with_pipes(null, args, null, GLib.SpawnFlags.SEARCH_PATH, null);
    let strOUT = '';
    if(success) {
        let out_reader = new Gio.DataInputStream({base_stream: new Gio.UnixInputStream({fd: out_fd})});
        let [out, size] = out_reader.read_line(null);
        while (out !== null) {
            strOUT += ByteArray.toString(out) + '\n';
            [out, size] = out_reader.read_line(null);
        }
        out_reader.close(new Gio.Cancellable()); // NEW LINE
    }
    callback(strOUT);
}

Maybe closing that input stream will do some good. :worried:

I'll give it a try...

Hey,

OK, so after printing some staff yesterday, the issue seemed to happen again:

On your second output I can find the same code lines (namely printers@linux-man.org/extension.js:108 and printers@linux-man.org/extension.js:202). Did you really added that extra line to "spawn_async" function? If the error occurs at that lines, they should be +1. Otherwise, it's a random crash.

Lack of activity...
