145758 - Winzip can not handle certain GZipped TAR files downloaded by Mozilla

Status: VERIFIED DUPLICATE of bug 132702

(Core Graveyard :: File Handling, defect)

Description

[Joseph Ferris]

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.0rc2)
Gecko/20020510
BuildID:    2002051006

When using the link in the URL (http://php.holtsmark.no/base64img/), click the
"Download" button on the page.  It downloads the file (you can either save to
disk or open with Winzip), but the file will not open.  The error message from
WinZip reads "Error Reading Header after 0 Entries".

Downloading the file in another browser works as expected.

Reproducible: Always
Steps to Reproduce:
1. Visit http://php.holtsmark.no/base64img/ with build 2002051006
2. Click download button
3. Open with Winzip

Actual Results:  Error Message from Winzip regarding malformed headers in
downloaded file:

"Error Reading Header after 0 Entries"

Expected Results:  Should have opened the TAR Archive.

OK.  so I have no WinZip, but if I save the file to disk on Linux I can gunzip
and untar just fine...

Are you saving to disk and then invoking WinZip on the file?  Or are you
triggering WinZip directly as a helper application?

Comment 4

[Pieter Poorthuis]

the problem only occurs when WinZip is triggered as a helper application. 
bug nr 151201 (http://bugzilla.mozilla.org/show_bug.cgi?id=151201) has been
marked as a duplicate, but contains some useful info:
> Mozilla 1.0/Win2K doesn't know the extension .tgz
> You could define it in preferences->helper applications, but until I did that, 
> I got this error:
> The mime type of the download is "application/x-gzip", so if I open the 
> download directly from Mozilla, WinZip is launched. WinZip shows that the tgz-
> file consists of one tar-file, but cannot open it.
> Because the original .tgz is correct, Mozilla does something wrong.

Does the server send a different filename on Windows?  Because on Linux it sends
a .tar.gz and so bug 151201 does not apply....

[Michael Gabriel]

yeah, mozilla is saving it to base64img.v2.2.tar.gz.tar
reporter, rename it to base64img.v2.2.tar.gz and try opening it with winzip
dupe of bug 120327, lets all pray mozilla will finally stop screwing with filenames

Comment 7

[Boris Zbarsky [:bzbarsky]]

This particular bit if screwing is utterly necessary to prevent certain security
exploits in the current helper app architecture on Windows (yay
ShellExecute()!), so don't hold out too much hope.... until someone takes the
time to redesign it from scratch.

This is basically bug 132702; marking it duplicate.

To clarify, the reason it won't open with winzip directly is bug 132702 (hard to
fix).  The reason it will not open with Winzip if you save it first is bug
120327 (much easier to fix).
