R devel - Dec 2007 - regression tests for unlink and wildcards fail - Solaris 10 SPARC / Sun Studio 12 (PR#10501)

Full_Name: Jim Brown
Version: 2.6.0 / 2.6.1
OS: Solaris 10 (SPARC)
Submission from: (NULL) (35.8.15.102)


I have been able to successfully compile version 2.5.1 using the Sun Studio 12
compilers on Sun Solaris 10 (SPARC).  All tests using "make check"
pass with a
status of OK.   However, the following section of "reg-tests-1.R"
fails when I
attempt to test after a build of either 2.6.0 or 2.6.1:

  ## regression tests for unlink and wildcards
  owd <- setwd(tempdir())
  f <- c("ftest1", "ftest2", "ftestmore",
"ftest&more")
  file.create(f)
  stopifnot(file.exists(f))
  unlink("ftest?")
  stopifnot(file.exists(f) == c(FALSE, FALSE, TRUE, TRUE))
  unlink("ftest*", recursive = TRUE)
  stopifnot(!file.exists(f))

  stopifnot(unlink("no_such_file") == 0) # not an error

  dd <- c("dir1", "dir2", "dirs",
"moredirs")
  for(d in dd) dir.create(d)
  dir(".")
  file.create(file.path(dd, "somefile"))
  dir(".", recursive=TRUE)
  stopifnot(unlink("dir?") == 1) # not an error
  unlink("dir?", recursive = TRUE)
  stopifnot(file.exists(dd) == c(FALSE, FALSE, FALSE, TRUE))
  unlink("*dir*", recursive = TRUE)
  stopifnot(!file.exists(dd))

  # Windows needs short path names for leading spaces
  dir.create(" test")
  dir(".", recursive=TRUE)
  unlink(" test", recursive = TRUE)
  stopifnot(!file.exists(" test"))
  setwd(owd)


If I comment out the above section of the tests, the rest of the test pass. 
However, running as it is intended, the "reg-tests-1.R" test does
fail.  Here is
the output that is generated from "make check":

running code in 'reg-tests-1.R' ...*** Error code 1
The following command caused the error:

And here are the final entries in the "reg-tests-1.Rout.fail" file:

"file281327c9"
[7] "moredirs/somefile"
> stopifnot(unlink("dir?") == 1) # not an error
Error: unlink("dir?") == 1 is not TRUE
Execution halted
rm: Cannot remove any directory in the path of the current working directory
/tmp/RtmpBLKy4b



Is this safe to ignore?   The empty directory that it is complaining about
(/tmp/RtmpBLKy4b) can not be removed using "rm -r", but can be removed
using the
UNIX "unlink" command.


Again, version 2.5.1 builds and checks just fine, but the above tests fail when
I attempt to build/check either 2.6.0 or 2.6.1.


In case it is any help, here are the configure options that I set for all three
builds:

  ./configure --prefix=/usr/local/R
  --with-blas=sunperf
  --with-lapack
  --with-tcl-config=/usr/local/lib/tclConfig.sh
  --with-tk-config=/usr/local/lib/tkConfig.sh
  R_PAPERSIZE=letter
  CC=/opt/SUNWspro/bin/cc
  CFLAGS="-mt -ftrap=%none -xarch=sparcvis"
  LDFLAGS="-L/usr/local/lib -R/usr/local/lib"
  CXX=/opt/SUNWspro/bin/CC
  CXXFLAGS="-mt -ftrap=%none -xarch=sparcvis"
  F77=/opt/SUNWspro/bin/f95
  F95=/opt/SUNWspro/bin/f95
  FFLAGS="-mt -ftrap=%none -xarch=sparcvis" 
  FC=/opt/SUNWspro/bin/f95
  FCFLAGS="-mt -ftrap=%none -xarch=sparcvis"
  CPICFLAGS=-xcode=pic32
  CPPFLAGS="-I/usr/local/include"
  SHLIB_CXXLDFLAGS="-G -lCstd"



For now, I think I will continue to use version 2.5.1 as I am able build/test
that version and I know it works.  However, I would like to upgrade at some
point and just thought I would make you aware of the failed test on the Sun
Solaris 10 (SPARC) platform using the latest Sun Studio 12 set of compilers.


Thanks.
