Hi!  
I have a serious issue that currently keeps me from redoing the figures for my publication. I’m working with vscode on our cluster head node with julia 1.10.4. When I open vscode and import / use modules at the start of a script, they are always recompiled, including all of their dependencies, again and again for every package imported. So some jlls even get precompiled several times. When I use the repl everything is fine. I tried to inspect the ENV var, but couldn’t find any obvious errors. Can you point me a way out of precompilation hell? I don’t know what I changed that made this mess happen, apart maybe from updating packages.

Are there several different login nodes? Julia usually precompiles new, if the cpu changes compared to the precompile cache. Or does it still precompile every time you restart the REPL even within the same login session (and without submitting some other jobs on the cluster that may also lead to recompilation)?

Just use the normal terminal in VSCode and start the REPL from the terminal.

does it work if you connect the REPL?

CTRL+SHIFT+p → “Julia: Connect external REPL”

Don’t know. I was never able to make that option work (and I’m away from the computer now).

Thanks for the replies so far! To clarify: There is just one login node and I control it. There are no other julia sessions running and all vscode / node processes are killed. When I start vscode and open the native julia repl in there, it precompiles all imported packages. When I use an independent repl there are no problems and miraculously, connecting to an external repl also worked! Last time I tried it didn’t o.O If that works consistently, I can use the external repl connection as a workaround. But I assume something is broken with the vscode extension…

How are you doing that? Are you using the menu option “Terminal → new Terminal” and then type `julia --project?`

And which terminal type do you use, is it bash?

I open the faulty vscode repl via Alt+J+O and the working repl I can connect to the way you described.

Just don’t use the Julia REPL from the Julia-vscode extension. It does too much behind the scene, is too slow, cannot easily be launched with different julia parameters and is too hard to debug if it fails.

I have a bash alias `alias jl='./bin/run_julia'` and a bash script `run_julia` which starts julia with all the options my project needs. Easy to debug and understand, always works, and it is fast. Typing `<ctrl><d>jl<enter>` restarts Julia if needed and never takes more than 1s.

After updating the vscode julia extension to version v1.110.1 the problem went away - hopefully it stays like that!
