[R-pkg-devel] Unusually long execution time for R.utils::gzip on r-devel-windows
FWIW, as far as I can tell, Sys.readlink() still doesn't handle symlinks (or junction points) on Windows. Were you thinking of normalizePath()? That does now resolve both symlinks and junction points on Windows (courtesy of a lot of work from Tomas), although I don't recall the exact versions in which support was introduced. But that would still give you a more efficient way of detecting such files on Windows. Kevin On Sat, Feb 17, 2024 at 3:21?AM Stefan Mayer

I can confirm that this has to fixed in R.utils. This gist is that
R.utils does lots of validation of read/write permissions, and deep
down it rely on system("dir") as a fallback method. If this is down
toward dirname(tempdir()), then it'll find a lot of files, e.g.

So, yeah, wow! I'll look into fixing this, probably by removing this
fallback approach, which is very rarely needed; it was added way back
when Sys.readlink() didn't cover all cases.
Thanks for looking into this, Henrik! Feel free to let me know if I can help with anything. - Stefan
