[klaus.berndl]

we loaded cgwin-docs_tar.tar, but we can not open it. tar says "hmm,
seems not to be a tar archive" and winzip read a header with 0 byte. Can
you help us ?

You have probably downloaded a *.tar.gz file with a Windows program
like Netscape. These programs rename auto. files with more than one
point in it to a name with underscores and so on (this is very annoying).
You can avoid this if you already correct the name in File-Save dialog of
netscape.

Rename your already loaded file cgwin-docs_tar.tar to cgwin-docs.tar.gz and
extract it with "tar -xzvf cgwin-docs.tar.gz" and it will work
(i hope :-).

Ah, you MUST be NT users. :)
IIRC, this is a NT-only problem. I never had this behaviour with a Win9x
machine, honestly, *never*.
However, my machine at work is a NT 4 SP 5 (?) one, so I always get   ...
_tar.tar  files instead of tar.gz. This is *very annoying*.. :-/
I do NOT have W2k yet, so I dunno if this is fixed in W2k. I hope it is, but
I bet it's not.

One (small) problem.  Netscape assumes that .bz2 files are text, and
displays them within the browser window.  To get a download, you *must*
right-click/save-as, you can't just left-click.  Not a big deal, but it
will generate FAQs.

[Robert Collins]

further to this,
    I have seen the following issues with browsers downloading tar.gz files:
* Sometimes they come down in text mode. Urggh. I don't know why and have
never seen it replicated.
* In IE if you download a .tar.gz file as anything other than "all files" in
the save as dialog, IE ungzip's it. This is due AFAICT to a broken
Content-Encoding implementation.
* occasionally name mangling can occur.

The only one that I know happens, and happens frequently is the IE save as.
As IE doesn't understand bzip2 (AFAIK) using bzip2 may also make browser
downloads more robust....

Unfortunately I cannot volunteer to tackle the setup changes :[

Hey, good idea!  I've been wanting to adapt setup.exe to use bz2 files.
This is YA reason for doing this.

Nice idea but I think this would break all other tar versions, too.

I wonder if we can add a bit to our version of tar to make it produce
files that are unextractable using winzip.

You're free to do as you wish.  But, if you report such problems on this list
you will receive the stated advice.

WinZip doesn't support Cygwin links.  If the tar archive contains any of those
links (and some packages do) then you will not be able to use the unarchived
file as it was intended to be used.  WinZip has never been supported.  WinZip
also has that smart CRLF option and that in itself was enough to not use it.

This is an old discussion. WinZip has three problems which are very
annoying.

- tar archives are extracted with CR/LF conversion by default. This
  can be switched off fortunately by a config dialog.

- It doesn't create empty directories from the archive.

- Worst: It doesn't know of Cygwin symbolic links so they are extracted
  without setting the system bit.

That's it and these are the reasons for suggesting not to use WinZip
for unpacking. Especially newbies will not be able to figure what's
gone wrong.

[Larry Hall (RFK Partners, Inc)]

Of course, anyone is free to do anything they want and, as long as it works
well for their needs, that's fine.  However, if you do something and have a 
problem and then ask the list, the first response will be to perform the 
operation in the prescribed way.  This is simply to reduce the variations
and determine if the problem is in Cygwin or not.  Also, the recommendations
given are used because they are known to work.  Recommending known working
procedures and discouraging those that don't or are problematic simply cuts
down on the traffic on this list.  So feel free to use whatever tools work
for you in whatever combination you like.  If, however, you find a problem
in your procedure, please verify that it is a problem using the recommended
procedure as well before posting.  This will save us all allot of time and
effort. 

In case its not clear, this response is directed at the reader of this message
as much as the poster!;-)

I use Netscape almost exclusively to download files, without problems.
Sometimes Netscape will automagically decompress the file, but not
rename it. So all applications that key off of the file name extension
will be confused. It's a simple matter to rename the file to end in
".tar". Also, see below.

  EB> 2) Don't use Winzip to explore a cygwin archive file.

I do this as well without problems, although it's not my preferred way
of exploring a gzipped tar gile. WinZip will ask if it should decompress
the file to a temporary directory and open it, which it does admirably.
Also, see below.

  EB> 3) The name of the file should be cygwin-docs.tar.gz

"cygwin-docs.tgz" could work as well. See below.

  EB> Cheers,

I have registered two new file types in Explorer to make my life easier:
In Tools:Folder Options:File Types, I've added
  
  GZ  --> WinZip

You might have to do the same in Netscape (Edit:Preferences:Applications).

2) Don't use Winzip to explore a cygwin archive file.
3) The name of the file should be cygwin-docs.tar.gz
