Rcmd check fails on Windows Samba network path in R 2.9.1

Hi,

The problem almost certainly has something to do with Samba. ?We also have a
NetApp file system, and copying the package source to that drive and running
Rcmd check from Windows works just fine.

When running the commands from an interactive R session, file_test returns
TRUE and file.access to test write permission indicates a failure, even
though that information is incorrect.Here is a session transcript:

-----------------------------------------

getwd()

[1] "n:/krc/Umpire/R-Package"

lib <- "Umpire.Rcheck"
file_test("-d", lib)

[1] TRUE

file.access(lib, 2)

Umpire.Rcheck
? ? ? ? ?-1

dir.create(paste(lib, "testdir", sep='/'))
dir(lib)

[1] "00check.log" ? "00install.out" "testdir" ? ? > sessionInfo()
R version 2.9.1 (2009-06-26)
i386-pc-mingw32

locale:
LC_COLLATE=English_United States.1252;LC_CTYPE=English_United
States.1252;LC_MONETARY=English_United
States.1252;LC_NUMERIC=C;LC_TIME=English_United States.1252

attached base packages:
[1] stats ? ? graphics ?grDevices utils ? ? datasets ?methods ? base
----------------------------------------
Again, this all worked (and still works) correctly in 2.8.1.

This error message looks like it comes from src/library/tools/R/install.R,
which contains the following test:

? if (!.file_test("-d", lib) || file.access(lib, 2L))
? ? ? stop("ERROR: no permission to install to directory ",
? ? ? ? ? ?sQuote(lib), call. = FALSE)

The function .file_test() is defined earlier in the same file (it looks at
file.info(lib)$isdir) and appears to be intended to be the same as
utils:::file_test().

You could start trying to figure out what the problem is by trying these
calls on the directory in question from an interactive R session.
(They seem to work as intended on my Windows system with a NetApp file
system mounted on a letter drive.)

Hi,

I have just updated R from version 2.8.1 to version 2.9.1. ?I am running
Windows XP Professional, Service Pack 3.

With the update, I decided to update a set of packages that I maintain by
compiling them for the new version. ?Everything worked fine except for one
package. ?This package is unique (among the six I was working on) in that is
stored on a UNIX-based file server that is exported to the Windows network
via Samba. ?The root of that network path is mapped to drive "N:" on the
local machine.

'Rcmd check' fails for this package under 2.9.1. ?The error message in
'00install.out' ?is:
"Error: ERROR: no permission to install to directory
'N:/krc/Umpire/R-Package/Umpire.Rcheck'"

'Rcmd check' works for this package under 2.8.1.

'Rcmd check' works for this package if the directory is copied onto a
local hard drive instead of the network drive.

'Rcmd build' and 'Rcmd build --binary' work under both versions.

It would be nice if someone could figure out what has changed and fix
it....

Best,
