Re: gunzip crc error :(

[Shing-Fat (Fred) Ma]

Hi again,

I installed gzip-1.3 and made sure it was the gzip being
invoked.  Still getting the CRC error.  Strange thing, though,
I extract the last file in the tgz archive, and it compares
perfectly with the unarchived file.  The gzip FAQ said that
gzip would eventually have error recovery features allowing
it to retrieve files past the point of a CRC error in a tgz file.
Maybe this is it.  Either that, or the warning is benign.

Another thing which shed some light on it is the output from
the "tar|gzip" command; "tail" applied to this output file gives:

     .gnome/apps/
     .gnome/apps/Multimedia/
     .gnome/apps/Multimedia/realplayer.desktop
     .gnome/mime-info/
     .gnome/mime-info/realplay.keys
     .gnome/mime-info/realplay.mime
     .RealNetworks_RealPlayer_60
     .Xpdefaults
     tar: Removing leading `/' from absolute path names in the archive
     var/mail/fma

".Xpdefaults" was the file which was succesfully extracted
despite CRC errors.  But there are more messages after that.
In particular, tar removes the "/" from "/var/mail/fma".  Maybe it
tries to go backward in the tar file to do this.  Since there is no
actual tar file, could it possibly be messing up the tgz file?  Kind
of a long shot, cuz it's more likely that the "/" removal happened
on the fly as the tar output is created.  In that case, the tar
message was actually generated much earlier, and was deferred
to the end of the message output file.
