FWIW, the binaries on https://duckdb.r-universe.dev/duckdb are built
with _R_SHLIB_STRIP_: TRUE and those are indeed around 10M (both for
Linux and MacOS).

For similar reasons p3m (formerly rspm) also strips debugging symbols
these days, e.g:
https://p3m.dev/cran/latest/bin/macosx/big-sur-x86_64/contrib/4.3/duckdb_0.10.1.tgz

I agree it would be nice for a package to be able to opt-out
altogether, including on CRAN. I don't think that is possible right
now.

[R-SIG-Mac] Debugging Symbols

2024-04-04 Thread Hannes Mühleisen 
Hello List,

we would like to bring up the topic of debug symbols in the CRAN OSX
binaries again. I realize this has been discussed before [1] and
realize the symbols are there for a reason, but in the duckdb package
their inclusion is particularly problematic.

Currently, the CRAN binary for OSX Arm64 weighs in at a whopping 97 MB
[2]. Inside it lives a 311 MB (uncompressed) folder with the debugging
symbols. When I remove the debugging symbols and re-create the
compressed tarball, its compressed size goes down to 11 MB, a pretty
drastic difference.

We are getting feedback from users that the package is too large for
them to be useful, so we would really like to improve this situation.

Would it perhaps be possible to exclude the duckdb from the inclusion
of the debug symbols? Is there anything we as package authors can do
here? There also may be other packages where this is relevant, e.g.
arrow would go down from 82 MB to 12 MB.

Best and thanks

Hannes
