Warn about cycles in extension precompilation #53882

@IanButterworth IanButterworth commented Mar 28, 2024

Currently the reason for these errors isn't clear.
If we can't avoid the error, at least explain where the cycle is so the user has a chance to fix it.

#53112 is the original version that instead tried to succeed.

Helps #53081
May help #52511

Ok, I'm confused now. This is detecting and warning about the cycle, but it's not causing the @errors seen in #53081

Any idea what's changed here @KristofferC ?

Ok, I don't know why the FillArrays Ext cycle doesn't error, but the reason that this example didn't @error in the same way as #53081 is that Symbolics has since worked around the issue (as of v5.17.0)

@KristofferC see a380337 (#53882) for why it was warning for FillArrays. I don't quite understand the increment decrement code around there, but it seemed to be in the wrong place.

Now seems to work
