Description:
|
This loop in mkdir_p
until path == stack.last # dirname("/")=="/", dirname("C:/")=="C:/"
stack.push path
path = File.dirname(path)
end
produces an array that includes "/", despite it's apparent attempt to exclude "/". Later, it calls fu_mkdir, which chomps off the slash and tries to run Dir.mkdir "".
An strace demonstration:
$ strace -e mkdir -f jruby -e 'require "fileutils"; FileUtils.makedirs("/tmp/A/B")' 2>&1 | grep mkdir
[pid 1871] mkdir("/tmp/A/B", 0777) = -1 ENOENT (No such file or directory)
[pid 1871] mkdir("", 0777) = -1 ENOENT (No such file or directory)
[pid 1871] mkdir("/tmp/A", 0777) = 0
[pid 1871] mkdir("/tmp/A/B", 0777) = 0
This does not normally cause problems even though one might say that the code is "incorrect". Where it tripped me up was with my Java SecurityManager. I forgot to tell it that it's OK to write to "".
