[Zope] problem.

[Tom Deprez]

Hi,

I'm propably overlooking something, but I'm facing here a problem which I
can't solve right now. Perhaps somebody knows the solution. I'm creating =
a
zip file and then return that one to the browser so that the user can
download it. The problem is that the created file turns out to be corrupt=
 ie
the data is altered. You can see this below, where I show you the file wh=
ich
I zip and then the file after unzipping the downloaded file. Does somebod=
y
has an idea? I've also problems with PDF files and I'm starting to believ=
e
that this is the same problem.
I'm running zope 2.4.1 on a windows nt machine
Thanks in advance.

Before Zip:

After Zip:

If I look in a  textfile the above returns etc were also transformed.

Used code:

import zipfile
import tempfile

def zipfolder(self):
    filename=3Dtempfile.mktemp()+'.zip'
    zip=3Dzipfile.ZipFile(filename,'w',zipfile.ZIP_STORED)
    zip.write('c:\install.log')
    zip.close()
    return open(filename).read()

and method calling above code:

<dtml-call "REQUEST.set('Content-type','application/zip;')">
<dtml-return expr=3D"testzip()">
