bug in cp: Permission denied

bug in cp: Permission denied

[John Wiersba]

What's up with this?

touch a
cp -p a b
cp: b: Permission denied

The copy actually works, and the timestamp is copied, but not the
permissions. 

I'm running b19 with coolview on NT with everything binary-mounted.

I don't have ntea set, but I'm not using NTFS either (I'm using FAT).
However, when I set ntea, I get even stranger results:

RE: bug in cp: Permission denied

[John Wiersba]

Now, I'm even more confused about cp.exe (see output below).  Can anyone
explain what's going on?

Second question: how do I tell what service pack I'm using?  The System
Properties shows 4.00.1381 and uname -a shows "CYGWIN32_NT machinename
4.0 19.3 i686 unknown"

I get this with NT 4+SP4 and b19:

HOME_lhall->touch 10101010 asdf

HOME_lhall->cp asdf fdsa1
HOME_lhall->cp -p asdf fdsa2

The only difference is touch seems to use the "default" group I'm in
(Administrators) rather than my user id like yours does.  This seems
to point to a permissions problem (although I'm not sure I understand
the behavior of touch either).

RE: bug in cp: Permission denied

I get this with NT 4+SP4 and b19:

HOME_lhall->touch 10101010 asdf

The only difference is touch seems to use the "default" group I'm in
(Administrators) rather than my user id like yours does.  This seems
to point to a permissions problem (although I'm not sure I understand
the behavior of touch either).

No.  a and b were meant to be generic file names.  I have tested this
several times in different (empty) directories in different file
systems.  In all cases, I get the same behavior, i.e. the file contents
and timestamp are copied correctly but the file access mode is not.

Here is a copy of a post I made yesterday to gnu-win32@cygnus.com which
didn't seem to make it into the mailing list (why not??):

Re: bug in cp: Permission denied

[Matt Behrens]

Actually, that doesn't make much sense.  COM1, LPT1, AUX, and their
brethren  operate with different DOS semantics than drive letters.  This
is evidenced by the fact that in any DOS command prompt,

	C:\> COPY FOO.TXT A
		and
	C:\> COPY FOO.TXT A:
		are different, but

	C:\> COPY FOO.TXT AUX
		and
	C:\> COPY FOO.TXT AUX:
		are identical.

Re: bug in cp: Permission denied

[Larry Hall]

'b' is a device under Win32??  Where in the FAQ does it say this???  What
the hell is 'b'?

I'm assuming that 'b' is not already a file in the directory where John was
trying this and that the proper permissions exist for that directory.  I
find the sequence John reports works fine for me with b19 + coolview on
NT SP4.

RE: bug in cp: Permission denied

[John Wiersba]

Can anyone reproduce this on a WinNT4 machine under b19 (or maybe under
b20)?

$ touch 10101010 asdf
$ chmod 444 asdf
$ cp asdf fdsa1
$ cp -p asdf fdsa2
cp: fdsa2: Permission denied
$ ls -l
total 0
-r--r--r--   1 jrw      jrwg            0 Oct 10 10:10 asdf
-r--r--r--   1 jrw      jrwg            0 Nov  4 09:57 fdsa1
-rw-r--r--   1 jrw      jrwg            0 Oct 10 10:10 fdsa2

Note that the -p option correctly copies the timestamp, but that the
file access mode is NOT
copied (I assume that's why there's an error message).  

Why can't the file access mode be copied?

I'm running b19 with coolview under WinNT, I don't know which service
pack, but the System Properties shows 4.00.1381.

What's up with this?

touch a
cp -p a b
cp: b: Permission denied

The copy actually works, and the timestamp is copied, but not the
permissions. 

I'm running b19 with coolview on NT with everything binary-mounted.

RE: bug in cp: Permission denied

[Earnie Boyd]

I don't have any definitive answer but my assumption is that cp still
has the file "copied to" open for write when it is trying to change
the permissions to read only, or it is a timing issue with the close()
function actually getting the file closed and the chmod() function
trying to change the permissions with the chmod() function winning the
race.

Re: bug in cp: Permission denied

b is a device under Win32.  The FAQ states that files named similar to
a MSDOS device will give you problems.  Actually, I'm surprised that
you didn't get an error with a also.
