Inference hangs on some files

[marijnh]

Example: http://underscorejs.org/underscore-min.js

[sergeche]

infer.js still fails on minified underscore.js, it happens when I request completions:

IndexError: RangeError: Maximum call stack size exceeded ( js/infer.js @ 43 : 21 )  ->       if (this.types.indexOf(type) > -1) return;

[marijnh]

It works for me now. Can you describe how you're running Tern when this happens?

[sergeche]

I’m running Tern on a project with 30 files. It happens when I’m requesting completions like so: https://github.com/sergeche/ternjs-sublime/blob/master/ternjs/js/controller.js#L205

Altho, it works fine on simple project with two files. I’ll try to narrow down my tests to figure out when this error appears.

I'm seeing something similar:

With one good sized file in its own directory (jquery-1.7.js, about 9300 lines) I add the following lines of code by hand (don't cut and paste all at once) about 2/3 of the way down the file:

var x = "foo";
var y = x.length;
var x1= "bar";
var y1 = x1.length;
var x2 = "baz";
var y2 = x2.length;
var x3 = "33333";
var y3 = x3.length;

The time required for each succeeding hint increases from 700ms to 5800ms to 38900ms etc. All the time is spent in infer.js in the inferWrapper AST walk, but I don't know why. It might be the same problem you're seeing.

@jeffkenton Are you using the current code? Some changes were made yesterday that should help with this.

[jeffkenton]

Not yet. I'll try it.

Thanks.
