[R-pkg-devel] File name error

Uwe/Kurt, is this 

controlled by R itself or by the host system?  I
suspect one of my R.filesets tests(*) fails (since a few days) because
of this, but it might actually be a false positive.  I fail to
reproduce it on Ubuntu 16.04 with:

* using R Under development (unstable) (2017-12-20 r73933)
* using platform: x86_64-pc-linux-gnu (64-bit)

My test tries to verify that it can write to tempdir() using its
*relative* path (if such is possible) - a test that effectively does:

abs <- tempfile()
setwd(dirname(abs))
getwd()

[1] "/tmp/Rtmpa9riPQ"

rel <- file.path("..", "..", abs)
rel <- gsub("//", "/", rel, fixed = TRUE)
rel

[1] "../../tmp/Rtmpa9riPQ/file3251441e380d

cat("hello", file = res)

and fails in that last write on 'r-devel-linux-x86_64-debian-gcc'.  It
could, of course, be a bug in my code that is now being revealed, but
these tests been in place for many years, possibly more than a decade.

This is a new check:

You must not write into the user's filespace without explicit agreement by
the user (by specifying path/name).

Note that some users won't even have permissions to write into the package's
installation directory if that is set up site wide by an admin, for example.

So please use tempdir() in the examples.

Hi Cathy,

I also had troubles with debian (Fedora only gave warnings) and no
problems with other systems. Mine was related to me writing a file (or
rather trying to write) in a working directory other than tempdir (can be
retrieved by tempdir()). I now write it to tempdir and then set the old
working directory again at the end of the example. Perhaps that is somehow
helpful for your case too?

I can highly recommend to test your tar.gz file with the check() function
of the rhub package. You can for example run check("pathtoyourpackage",
platform = "debian-gcc-devel") or
check_for_cran("pathtoyourpackage", platform = "debian-gcc-devel"), i.e.
test your package on debian without troubles.

Best,
Christine

I am getting the following error from the auto-checks when trying to
submit a package to CRAN:
r-devel-linux-x86_64-debian-gcc

<https://cran.r-project.org/web/checks/check_flavors.html#r-devel-linux-x86_64-debian-gcc>

Error in pdf(file = fileName4, width = 8, height = 10) :

Since this works for ALL other flavors, I am assuming it may be some file
name restrictions unique to debian-gcc???  I can't think what else would
cause it to fail only in the OS.

debian doesn't like "--"?
