[BUG] Editor not responding for large for loop

[Kevin-Mattheus-Moerman]

Details

• Atom version: 1.38.2
• Julia version: 1.1.1
• OS: Ubuntu 19.04
• Package versions:
  • Atom.jl: 0.8.5
  • julia-client: 0.8.9
  • ink: 0.10.10

Steps to reproduce

1. Run script below

using LightXML
using Printf

A=randn(25000,3)

xdoc = XMLDocument()

# create & attach a root node
xroot = create_root(xdoc, "Nodes")

for i=1:size(A,1)
    # Create string
    s="" # empty string
    for j=1:size(A,2)
        s*=@sprintf("%.8E, ",A[i,j])
    end

    # create the first child
    xs1 = new_child(xroot, "Node")
    set_attribute(xs1, "id", @sprintf("%i",i))
    # add the inner content
    add_text(xs1, s[1:end-2])

end

If I run the above I keep getting a "Editor not responding" error. Am I doing something wrong or is this a bug?

I can't repro this issue, but I think the issue is that xroot's and xdoc's DOM representation are too big or something like that.
Will take a look at fixing that...

@pfitzseb thanks for checking this out.

Have you tried using A=randn(250000,3) or an even larger array?

Is "xroot's and xdoc's DOM representation" a Julia thing or a LightXML thing? (I'm wondering if I should raise the issue with LightXML).

[pfitzseb]

It's a Juno thing, so you are in the right place :) And yes, bigger arrays will probably crash the editor for me as well.
As a short term workaround you can just close the workspace and take care to never display xroot's or xdoc's content in the editor ever.

Thanks I tried it and it works. 🎉

Fixed with JunoLab/Atom.jl@445e3c9, afaict.
