Hi,
I am getting an error from one of the test files
tests/reg-tests-1.R using the unstable version (r50179).
(i've learned my lessons; this is a clean build.) The tail
of reg-tests-1.Rout.fail is
Loading required package: myTst
building package pkgA ...
installing package pkgA using file pkgA_1.0.tar.gz ...
Error in as.octmode(mode) : invalid digits
Error in install.packages(r, lib = "myLib", repos = NULL, type = "source") :

I think I have tracked this down to the following line in utils:::untar2()
mode <- rawToChar(block[101:107])
mode contains a trailing space as in "000755 " which causes the invalid
digits error in as.octmode(). If I change the line to
mode <- rawToChar(block[101:106])
untar2("pkgA_1.0.tar.gz") unpacks the test package but I, of course,
do not know whether this is a general fix.
Am I the only one seeing this problem (FreeBSD 9.0-CURRENT)?
Seems this is a bug in the tar program on your OS: this should be
'0000755(nul)' in the 8 bytes 101:108. And that's in every account of
the tar format I have found, including the former POSIX standard.
(Note to Peter D: we don't use getOct for this one, as it is not a
field that is allowed to be space-padded.)
I guess we need to work around this ... to a large extent we have got
away with using tar format in the past because everyone was using GNU
tar, but others are coming into use.
[A quick check confirms that bsdtar from the libarchive project does
this, as used by Snow Leopard and AFAIK FreeBSD >= 8. So I can
reproduce it.]
