Revise not tracking subdirectories inside WSL2 when updating LOAD_PATH variable

[juandarias]

• MWE

1. Create a subdirectory src or any other name in your working directory. The working directory has to be inside a mounted windows partition

2. Create a file MyModule.jl in subdirectory with content:

module MyModule

export anotherfunc

function anotherfunc(x)
    display(sin(x))
end

end

3. Run julia from working directory and execute following code:

push!(LOAD_PATH, pwd()*"/src")
using Revise
using MyModule
anotherfunc(0)

4. Edit MyModule.jl to display(cos(x)). Output of anotherfunc(0) in REPL doesn't change

• System

1. Julia 1.5.2
2. Revise 3.1.14
3. Ubuntu 18.04 in WSL2

Can't reproduce. Perhaps you were loading MyModule from an earlier entry in LOAD_PATH? What happens if you instead of push! use pushfirst!?

@fredrikekre: It seems to be because the folder and files were inside a mounted partition inside WSL2!

So actually I am using WSL2 with Ubuntu 18.04, and the tests I performed were with files inside the mounted Windows partition. So any test with files inside "/mnt/c/" fails.

With files inside the Linux filesystem, the behavior of Revise is the expected one.

Perhaps, this is not an issue of Revise at all.

Ok, probably #514 then?

[juandarias]

Yes, that seems to be the problem. Only for the record, if the module is in the working directory and not a subdirectory, the behaviour is the correct one.

I'll close this as a near-duplicate of #514, but I linked back here for the info re subdirectories. Thanks to both!
