#3083: Bad handling of URLs in IE5/6 when downloading files in raw format

Hello,
The problem really lies in Internet Explorer I think and not trac but the
fact that the URL for original format links would be of the form
".../file.exe?format=raw" (or any other binary type) makes IE want to save
a file called "file" without the extension, and thus... that cannot be ran
afterwards. It also happens for example when the URL is
".../file.tgz?format=raw" in which case IE renames it to "file.tar"!???! I
have tried to look for solutions on the web but could only find people
with the same problem. One of the suggestions, though, was to add to the
HTTP header a `Content-Disposition` field which forces 1) a download and
2) a filename (this HTTP feature is described in RFC 1806).
I have patched my own working copy of trac with the following code (file
`versioncontrol/web_ui/browser.py`)
in `_render_file`:
{{{
format = req.args.get('format')
if format in ['raw', 'txt']:
req.send_response(200)
if format == 'raw':
filename=node.path.split('/').pop()
req.send_header('Content-Disposition', 'attachment;' + 'filename='
+ filename)
req.send_header('Content-Type',
format == 'txt' and 'text/plain' or mime_type)
req.send_header('Content-Length', node.content_length)
...
}}}
And it seems to do the trick for IE: when clicking on raw versions, IE now
proposes to save the file with exactly the file name that we send in the
HTTP header.
I'm not sure you will want to fix IE bugs with workarounds :-) but just in
case, I fill this ticket. Thanks for the attention.
Cheers,
Christophe.
