Found non-API call to R: ‘R_NamespaceRegistry’

[pepijn-devries]

Thanks for your work on cpp11!

I recently got a note on CRAN checks in one of my packages that uses cpp11:
https://www.r-project.org/nosvn/R.check/r-devel-linux-x86_64-fedora-clang/blosc-00check.html
It says:

File ‘blosc/libs/blosc.so’:
  Found non-API call to R: ‘R_NamespaceRegistry’

Compiled code should not call non-API entry points in R.

As my code doesn't use this registry directly, I suspect that it originates from its cpp11 dependency. More specifically, I'm using auto utf8ToInt = package("base")["utf8ToInt"]; in my code, which is eventually using:

cpp11/inst/include/cpp11/function.hpp

Line 70 in adfb240

return safe[detail::r_env_get](R_NamespaceRegistry, name_sexp);

Is it possible to update this function, such that it only uses entry points in C that are allowed on CRAN? Or should I address this downstream in my package?

Thanks, R_NamespaceRegistry is a pretty critical part of how pkgload works, so we will probably need to discuss this removal with R Core.

There should be nothing you need to do in the meantime. If you send in a package release and they reject it due to this, just tell them it comes from cpp11 and they should let you through.

Thanks for the quick response. I don't have any updates planned anytime soon for this package. So for the time-being I will just let it be.
