Rakefile under Cygwin: permission denied

[Jim Menard]

The Rakefile

task :default => ['foo/bar']

directory 'foo'

file 'foo/bar' => ['foo'] do
sh 'touch foo/bar'
end

fails if both the directory 'foo' and the file 'bar' within it exist.

c:/cygwin/tmp/> rake
(in c:/cygwin/tmp)
rake aborted!
Permission denied - foo
c:/cygwin/tmp/>

As you can see from the command prompt, this is under Cygwin.

Am I doing something wrong?

Did you verify that the commands work from the prompt? Otherwise I'd
suspect a permissions problem.

This is Windows XP and my login has admin privileges: what permissions?

Actually, what's failing is deep inside rake. Its "timestamp" method calls

File.new(name.to_s).mtime

but the "File.new('foo/bar')" is what fails with the "permission denied"
error. When I do "ls -l" (I'm using Cygwin)

~> ls -l foo
total 0
-rw-rw-rw- 1 JMenard 5 0 Jun 14 09:32 bar
~> ls -l foo/bar
-rw-rw-rw- 1 JMenard 5 0 Jun 14 09:32 foo/bar

As far as I know the complicated rights management of Win / NTFS I suspect
it is possible to reject permissions even for admins. So, this is an
option...

Then maybe you should post a stack trace to aid in Rake debugging.

Kind regards

Good point.

Why it's not
File.mtime(name)
or
File.open(name){|f| f.mtime}
?

I don't know why. File.mtime(name.to_s) works.

I've CC'd rake-devel. Consider this a change request: Please change the
implementation of timestamp to be

File.mtime(name.to_s)

because under XP, the current implementation

File.new(name.to_s).mtime

fails if name already exists due to a "ERRNO::EACCESS: Permission denied"
error.
