There seems to be an upper limit of the number of files (approx 1000 files) a
zip-file can contain when unpacking it with zip.unpack(). This results in an R
crash. This bug is urgent since install.packages() relies on zip.unpack() and
too big packages/bundles won't install with the current R v1.7.0 for
Windows.
The following R script creates a directory with N files and zips it and tries to
unpack it again. Try with a large number on N (N=1003 is probably enough) and R
will crash. The traceback from Dr. Mingw is pasted at the end.
# 1. Running the script several times with N = 900 crashes R or generates
# the error:
# Error in zip.unpack("dir.zip", "c:/tmp") :
# can not set length of non-vector
# 2. Running the script twice with N = 1002 crashes R
# 3. Running the script twice with N = 1003 crashes R (every time?)
# 4. Running the script twice with N = 2000 crashes R (every time!)
N <- 1003
# Create an directory with N files
dest <- "dir"
dir.create(dest)
files <- list.files(dest)
nMissing <- (N - length(files))
if (nMissing > 0) {
idx <- (length(files)+1):N
filename <- sapply(as.integer(idx), FUN=sprintf,
fmt="file%05d.txt")
pathname <- paste(dest, filename, sep="/")
for (k in seq(pathname))
cat(file=pathname[k], 0)
}
# Create a zip archive of the directory
zipper <- "C:/cygwin/bin/jar -cfM"
cmd <- paste(zipper, " ", dest, ".zip", " ",
dest, sep="")
system(cmd)
# Unse zip.unpack(), which is used by install.packages(), to unpack it.
zip.unpack("dir.zip", "c:/tmp")
