[on MS Windows] ERROR: Package MATLAB errored during testing (exit code: 3765269347)

[hatmatrix]

I've added MATLAB in Julia v1.11 through the package manager. I am running Windows 11 and MATLAB 2024b is installed. When I run

using MATLAB  # this is fine
mat"ver"

or any other MATLAB code in VSCode, I get:

The terminal process "C:\Users\testacct\.julia\juliaup\julia-1.11.2+0.x64.w64.mingw32\bin\julia.exe '-i', '--banner=no', '--project=C:\Users\testacct\.julia\environments\v1.11', 'c:\Users\testacct\.vscode\extensions\julialang.language-julia-1.127.2\scripts\terminalserver\terminalserver.jl', '\\.\pipe\vsc-jl-repl-159c2360-275d-4eda-9708-5697120d6478', '\\.\pipe\vsc-jl-repldbg-34439aaa-b352-4163-8607-b71adecda219', '\\.\pipe\vsc-jl-cr-929cae24-af6b-48c7-a83a-58fad01bbf68', 'USE_REVISE=true', 'USE_PLOTPANE=true', 'USE_PROGRESS=true', 'ENABLE_SHELL_INTEGRATION=true', 'DEBUG_MODE=false'" terminated with exit code: -529697949.

When running just the Julia terminal without VSCode, the terminal just closes. However, I have noticed that the MATLAB Command Window will pop up before exiting.

When I test the build:

ERROR: Package MATLAB errored during testing (exit code: 3765269347)

After testing I have checked "C:\Users\TESTACCT\AppData\Local\Temp\jl_tkJSKc" and it appears to be empty.

I believe this gentleman had the same error and suggested running the Julia terminal in Administrator mode for installation and testing.

However, having tried this I got the exact same error so it did not fix the problem in my case. Any ideas on what I can try next to get this running? Many thanks.

This kind of issues happen often on Julia with Windows.
My hunch (I may be wrong) is the process tries to delete a folder before the process of deleting all its contents is done.
Or accessing a folder / file before the process of creating it is done.

Probably has something to do with Windows being slower on small file operations due to its more advanced File System design.
I wonder if some pause somewhere would assist with that.

Indeed it seems to be a Windows error rather than a Julia error.

Is there a way to implement a pause? I assume it's not specific to MATLAB.jl but in the Pkg build function, though looking through Pkg.jl it's not so clear to me where that could be.

I don't think so.
It seems to be that a code is optimized for other OS's.
Windows' File System is very generic and built for having 3rd party Plug In's and other features which creates latency.
If some async operation does not take that into consideration issues might happen.

Again, just a hunch.

Is there a way to implement a pause?

I have a script in PowerShell which deals with files.
I had some issues with it and once I added a pause it worked well.
There should be a Pause in Julia. But it might be issue with a lower level library.

Note: #226 is not in the current release, so you may want the master branch instead. Not sure if this will help or not.

Happy to give commit access to folks who can help maintain the package, make releases, etc.

Was having this identical issue with Julia 1.11.2 and MATLAB r2023a. Removing the MATLAB.jl package and installing from master with,
add MATLAB#master
Fixed it for me.
