159833 - Progress dialog shows things incorrectly if a a file is sent via content-disposition: attachment

Status: RESOLVED WORKSFORME

(SeaMonkey :: Download & File Handling, defect)

Description

[Lev Povalahev]

When downloading files that are send using "content-disposition: attachment;"
the progress dialog title shows "-1% complete from file.ext" and the status
field is empty.

The title should be something like "receiveing file.ext" and Status fielt should
show now many KB/MB have beed downloaded so far.

Using Mozilla 2002072708 on WinXP.

Do you mean an Attchment in Mailnews ?

No, I mean Content-disposition field of a HTTP header.
This is a common way to start downloads through scripts, i.e.
lets say there's a URL www.host.com/download.cgi?aaaaaa.bbb

download.cgi writes this HTTP header:

Content-Type: somemimetype/ext Content-Disposition: attachment; filename=aaaaaa.bbb

and then sends the contents on the file aaaaaa.bbb.

See related bug 65827.  This is NOT a duplicate of that bug, but any fixes might
be related.  However, this worksforme on win2k at the following url:
http://www.bewley.net/cgi-bin/download.pl

component->Download manager

Please provide a URL this happens at.  I have been unable to reproduce it my tests.

I just tested it with the newest build:

In the download manager the entry is shown correctly: in the "transferred"
column there is "1201 KB of ??? at 79 KB/s".

In the progress dialog no progress other than the elapsed time is shown.

"Status:" in the download properties dialog does indeed remain blank rather than
showing the downloaded size on reporter's test link (where mozilla doesn't know
the length of the content).

confirming with 2002120908/trunk/win2k

manager window showing KB downloaded so far

This is a duplicate of the bug on downloads with no Content-Length being screwy....

bz: do you mean bug 123334?

Comment 12

[Boris Zbarsky [:bzbarsky]]

That, or we may have even older ones...

I think the summary isn't correct, the bug appeares when the Content-length
header is missing, doing content-disposition: attachment works fine with correct
Content-length.

Also, it seems to be fixed in Mozilla 1.4a (Build 2003040105). Here the download
window status shows "xxxx KB of ??? at xx KB/s"

When analyzing the packets sent/received to the server, it seems Internet 
Explorer sends nothing but User Agent, and Host, and receives Content Length 
from the server, but Firefox sends a whole list of accepts and other headers, 
and the content length is no where in the packet returned to Firefox from the 
server.

Marking worksforme, then (unless someone wants to evangelize the site).
