Comment 1 SB 2000-05-29 19:10:59 UTC

I don't believe this is a bug.  For instance this will always fail:

[root@king /]# rpm2cpio < kdebase-1.1.2-31.src.rpm >
kdebase-1.1.2-31.src.rpm.cpio
cannot re-open payload: Success
[root@king /]# l kdebase*
-rw-r--r--  1 root root    6171478 May 29 15:08 kdebase-1.1.2-31.src.rpm
-rw-r--r--  1 root root          0 May 29 15:12 kdebase-1.1.2-31.src.rpm.cpio

This always works:

[root@king /]# rpm2cpio kdebase-1.1.2-31.src.rpm > kdebase-1.1.2-31.src.rpm.cpio
[root@king /]# l kdebase*
-rw-r--r--  1 root root    6171478 May 29 15:08 kdebase-1.1.2-31.src.rpm
-rw-r--r--  1 root root    6230340 May 29 15:13 kdebase-1.1.2-31.src.rpm.cpio

Comment 2 John Gotts 2000-05-30 02:26:59 UTC

Well, the currently [in Red Hat Linux 6.2] nonworking form had worked for well
over a year, dating back at least to 5.x and including 6.0 and perhaps 6.1 as
well.  I wouldn't rule out the possibility that the feature was removed for some
reason, though.

Comment 3 Ed Avis 2000-06-09 09:22:15 UTC

The manual page still shows the old reading-from-stdin form.  So there must be a
bug either in the program or in the manpage.

Comment 4 Jeff Johnson 2000-06-23 14:52:35 UTC

Clearly there is a bug. Right now I believe the fix will be to change the
man page, but I'll take a look at fixing rpm2cpio. Meanwhile, either
add the file name on the command line, or add the token '-' to indicate
stdin.

Comment 5 Jeff Johnson 2000-08-07 13:37:47 UTC

This problem will be addressed after rpm-4.0 is released.

Comment 6 Jeff Johnson 2001-02-21 18:53:23 UTC

Here's the current man page:

DESCRIPTION
       rpm2cpio converts the .rpm  file  specified  as  a  single
       argument  to  a  cpio  archive  on  standard out. If a '-'
       argument is given, an rpm stream is read from standard in.

       rpm2cpio rpm-1.1-1.i386.rpm
       rpm2cpio - < glint-1.0-1.i386.rpm
