Incompatibility with master (3.8)

[jamshark70]

I realize this is a known issue, but I just tried to use ProxyMixer against a more recent SC and it broke because of JITLibExtensions. So I think it's worth logging to ensure the issue doesn't get lost: it's rather below an ideal situation if a quark is incompatible with the current stable release.

User impact: I just had to downgrade SC to my pre-3.7 sandbox branch to use specs with JITLib.

Post the code that caused it and the error stack. You know the routine - user posts "it doesn't work" and then runs away.

I think you mentioned on the list that it's actually 3.8-dev that it failed on.

[jamshark70]

First, yes, the initial bug report is mistaken. JITLibExtensions is fine against 3.7, but broken against 3.8. I'm updating the issue title.

Code snippet:

p = ProxySpace.new.push;
~synth = { |freq = 440| SinOsc.ar(freq, 0, 0.1) };
~synth.gui;

In this case, it's an error I had already discussed with Alberto some months ago.

There is no instance variable widgets anywhere, but it is called by two methods:

• EnvirGui.updateSliderSpecs
• NdefParamGui.updateSliderSpecs

e.g.:

updateSliderSpecs { |editKeys|
        var currState;

        if (object.isNil) { specs.clear; ^this };

        currState = object.getKeysValues;

        editKeys.do { |key, i|
            var currValue = currState.detect { |pair| pair[0] == key }[1];
            var newSpec = this.getSpec(key, currValue);
            var widge = this.widgets[i];
            if (newSpec != specs[key]) {
                specs.put(key, newSpec);
                if (widge.isKindOf(EZSlider) or:
                    { widge.isKindOf(EZRanger) }) {
                    widge.controlSpec = newSpec;
                    widge.value_(currValue);
                };
            };
        }
    }

It throws the error:

Dear all, fixed this so my tests work - see https://github.com/supercollider-quarks/JITLibExtensions/blob/master/JitGui_tests.scd

Please test with your setups, both in 3.7.2 and 3.8, and let me know if you still see any problems.

sorry for the long wait!

[telephon]

Works fine now (3.8) – thank you!
