Corrupted tar-ball in Cygwin-x86_64

Corrupted tar-ball in Cygwin-x86_64

[Angelo Graziosi]

When I try to update my Cygwin64 installation (on a virtualBox Win7-64 
installation) I get an error about the cygwin32-1.7.27-1.tar.xz package 
which seems corrupted.

This is confirmed from command line on which i get:

$ tar -rf cygwin32-1.7.27-1.tar.xz
tar: Impossibile aggiornare archivi compressi
tar: Error is not recoverable: exiting now


Ciao,
  Angelo.

last is is cygwin-1.7.27-2.tar.xz

$ md5sum cygwin-1.7.27-2.tar.xz
7dc5f90c8500701849b16648e3980320 *cygwin-1.7.27-2.tar.xz

why cygwin32 ?

Moreover:
-r, --append               append files to the end of an archive

 > tar: Impossibile aggiornare archivi compressi

as the message says (in italian) you can not append files
to compressed archive

Marco

	You need to tell tar to uncompress it for you -- or uncompress
it yourself.

For 't' try using
tar -taf fff.tar.xz

You've never been able to append a file directly to a compressed
archive.  You need to uncompress it first, append then recompress.

There is a typo here (on my part) which seems to have generated some 
confusion... :(

The command I have run to confirm the corrupted tar file was

$ tar -tf cygwin32-1.7.27-1.tar.xz

(the same reported by Marco here: 
http://cygwin.com/ml/cygwin/2014-01/msg00244.html), but when I wrote the 
email and then repeated it for the copy/paste, I typed the "r" instead 
of "t" and this caused the confusion..

I did not want to append any file...

Anyway, the most important thing is that now Yaakov has fixed the 
corrupted tar-ball (http://cygwin.com/ml/cygwin/2014-01/msg00249.html)


Ciao,
   Angelo.

I thought it was the case that 'a' was required on t/x as well as
'c', but can only verify that it used to need some extension it
could recognize, but now it figures it out w/no extension.

I.e.:
(old):
Astarte:/tmp> tar caf xxx.tar.xz 
server-0815527C63B5A57106C26703B2473B023EC30A19.xkm
Astarte:/tmp> mv xxx.tar.xz xxx
Astarte:/tmp> tar tf xxx
tar: This does not look like a tar archive
tar: Skipping to next header
tar: Exiting with failure status due to previous errors
(new)
/tmp> tar caf xx.tar.xz xx.sh
/tmp> mv xx.tar.xz xx
/tmp> tar tf xx
xx.sh
----

Guess somewhere I assumed 'a' was required for automatic compression
recognition... but only on 'c' it seems...

It is the case tar will decode even files w/o extensions...neat!.

Well that's the important part!
