unc filepaths not working

[jd4ds]

hello,

I’m experiencing some issues when trying to addLocalPackage to a repository on a unc file path like so

• \\\\\\\\fileserver\\\\dir\\\\minicran\\\\, or
• file.path('', '', 'fileserver', 'dir', 'minicran'), or
• //fileserver/dir/minicran/

it looks like that at least at one point in the code in the repoBinPath() function the normalization of the path does not work properly (maybe somewhere else as well) and converts the path to \\\fileserver/dir/minicran which tar() does not interpret correctly.

tar (child): \\\fileserver/dir/minicran/src/contrib/testpackage_0.1.0.tar.gz: Cannot open: No such file or directory
tar (child): Error is not recoverable: exiting now
/usr/bin/tar: Child returned status 2
/usr/bin/tar: testpackage/DESCRIPTION: Not found in archive
/usr/bin/tar: Exiting with failure status due to previous errors

Same Problem here:

miniCRAN::addLocalPackage(pkgs="mycomp.ABCde.Tools", pkgPath="../", path=file.path("//myserver/localrepo/miniCRAN"))
tar (child): \\myserver/localrepo/miniCRAN/src/contrib/mycomp.ABCde.Tools_0.0.0.9000.tar.gz: Cannot open: No such file or directory

R version 3.5.2

Because of this bug, Windows users can only use miniCRAN repositories on the local computer.
