ERROR: ArgumentError: stream is closed or unusable

[AndiMD]

Disclaimer, I am not sure whether this problem is caused by the Juno package. I can only reproduce it in Juno, not in the standalone Julia REPL.

The call to function get_sol causes a stacktrace if:

• The function get_sol is defined by running a script file (attached), and the call to get_sol is run in the REPL
• The function get_sol is defined and get_sol is called in the same script file, and the script file is run twice without restarting the REPL

I am on Kubuntu 17.04, Julia 0.6.2, Atom 1.23.2 x64 with Juno 0.1.2

The script I am trying to run is a modified version of this example http://www.juliafem.org/examples/2017-09-16-convection-diffusion-equation/index ConvectionDiffusionBug.txt

Thanks a lot! Andy

Are you using the new REPL-based console when the error happens? Can you try switching to the Legacy console in the settings, restart Atom, and try running the code again?

[AndiMD]

Spot on, thanks! The legacy console works fine. I can use this as a workaround until this is fixed.

[ianfiske]

Just want to add that I just encountered this same error as well with the new console. I use Memento.jl for logging. It works fine with the legacy console but the new REPL causes the same ERROR: ArgumentError: stream is closed or unusable error from within my package. Reverting to legacy for now.

MWE: Evaluate the following lines separately:

foo = STDOUT
print(foo, "hi")

Not sure how to best solve this, sadly.

Should be "fixed" by https://github.com/JunoLab/Atom.jl/commit/4907f6e92209c3493f4decc12477b156aa5b34ab.
