Excess precompilations

[joa-quim]

Hi,

Julia 1.10.0 on Windows here

These 4 steps each one precompiles the code (but in fact I can generate up to 6 if using a package that has GMT as a dependency)

1- using GMT from normal REPL
2- using GMT from VSC REPL (???)
3- ] test GMT
4- From pythoncall, jl.seval("using GMT")

Looking at the .julia\compiled\v1.10\GMT there are now 4 precompiled caches. I know the difference between 1 and 3 (was explained in a previous topic), but why the others? More in particular, why VSC REPL needs to recompile?

C:\Users\j\.julia\compiled\v1.10\GMT>dir
 Volume in drive C is OS
 Volume Serial Number is B071-46FE

I've observed the same when switching from 1.11.7 to 1.12

More in particular, why VSC REPL needs to recompile?

You'll have to check with the VSC people if they perhaps load something into the REPL or if different dependencies were used. When the existing precompile file is not valid to use, julia creates a new one up to a max of 10 where it starts to delete old ones. Nothing here suggests anything is going wrong with this process.

I have the impression that Julia might be storing precompiled caches in different places depending on the shell and how it's invoked. I know I've had to recompile all over again if I call from sudo, for instance. Could be that the shell VSCode is opening is different from the terminal and then the precompilation cache is found elsewhere.
Is there a way to know where the precompilation cache is?
