No finish notification evaluating a single line - Juno hangs/crashs/freezes

[VoSiLk]

I´m using Julia Pro 1.3.1-2 on Windows. I´m facing the same problem with Julia Pro as I described in #405 . I evaluate some lines by single line evaluation and suddenly at one line I get no finish notification, despite a evaluation in the REPL works.

For the following Debug Info Juno hangs during loading a big csv-file.

For anyone, who has the same problems the following setup with vanilla Julia 1.1.1 works for me,: Julia packages: Atom v0.9.1 Juno v0.7.2 Note: to install a specific version of julia package enter the package manager within the Julia REPL via ] and then use i.e add Juno@0.7.2 command

Atom packages: ink 0.11.7 julia-client 0.11.3 language-julia 0.19.2 uber-juno 0.3.0 Note: to install a specific version of atom package open a power shell window and then use i.e apm install ink@0.11.7 command

The debug info says you even couldn't connect to Julia properly. Are you sure you were running code by Juno ?

[VoSiLk]

I´m confused. How should I run the code not by Juno, when I´m working with Julia Pro? I just opened Julia Pro and pressed SHIFT + ENTER to evaluate lines of a script.

[aviatesk]

Sometimes users assume some features are provided by Juno, but sometimes they actually provided by other packages that enables code execution like Hydrogen etc. I'm curious how you can run code (within Juno) even when your Juno couldn't find a Julia.

well, as for this specific bug, https://github.com/JunoLab/Atom.jl/pull/300 will get rid of those dead lock issues.

[VoSiLk]

I´m not sure, but I think it could maybe have something to do with a change in Atom.jl, because if you compare the settings of #405 with my currently settings, which work, I could update all packages except for the Atom.jl package. Furthermore I didn´t experience this behaviour in an earlier version of Julia Pro, where also an older version of Atom.jl was uesd,

[pfitzseb]

We just released a new version of Atom.jl that you could try (not with JuliaPro, just in a normal Juno installation). JuliaPro 1.4 will also be out this week, in case you want to wait for that.

[VoSiLk]

Thanks. I'll try and report later in the day.

[VoSiLk]

The first test was successful. The problem doesn´t appear again. I will work the next days with the latest version and report the results.

[pfitzseb]

Awesome. Sorry it's taken us such a long time to track this bug down...

[VoSiLk]

It hangs again on a custom module. I tried to load manual with the REPL and it worked. So unfortunately the bug isn´t solved.

[pfitzseb]

Can you describe what you did just before the hang?

[VoSiLk]

I just restarted julia and loaded

using JLD2 using MATLAB using ACustomModule using CSV

[aviatesk]

It may be possible that your script made Juno's static code analyzer crazy (will appear as memory consumption explosion usually). If so it will be helpful if you share your script with us.

[VoSiLk]

I would like to do this, but it isn´t so easy, because I use Julia for my work at a company and therefore I can´t simply share the code. Sorry.

[pfitzseb]

Right, makes sense. Can you keep an eye on memory and cpu consumption in the task manager?

You could also give the first patch suggested here a go, that might help.

[VoSiLk]

Thanks. I will try it.

[pfitzseb]

Oh, one more question: Do you have Revise loaded while running your code?

[VoSiLk]

Yes I have put it in the startup like this:

ENV["JULIA_REVISE"] = "auto" ENV["JULIA_REVISE_INCLUDE"] = "1" ENV["JULIA_REVISE_POLL"] = "1"

atreplinit() do repl try @eval using Revise @async Revise.wait_steal_repl_backend() catch end end

[pfitzseb]

Can you check if you see the same error without Revise (in the neweset Juno release)?

[VoSiLk]

It doesn´t hangs until now and I notice that the loading of the modules is much faster.

[timholy]

Try without all those ENV customizations, especially the INCLUDE one. (You're certain you need POLL? Your code is on an NFS mount?)

[VoSiLk]

Oh, I think, when I first configured my startup file, I read something different "NTFS" and copied this code sequence. So I will try it :)

[VoSiLk]

For the moment I would say, that this was the problem. Thank you very much for your help and time :) . Despite this I would like to investigate it a little bit longer, because I had it several times, that I thought the problem is gone and it wasn´t.

[timholy]

I read something different "NTFS" and copied this code sequence.

Thanks for letting me know, I can totally see how that would happen. I will tweak the docs to emphasize that the two are not the same.

[pfitzseb]

Ok, I'll close this for now then. Feel free to reopen if you run into similar issues again.

[VoSiLk]

Thank you
