173405 - (autoresume) Auto-resume feature for disconnected and cancelled downloads

Status: RESOLVED DUPLICATE of bug 18004

(SeaMonkey :: Download & File Handling, defect)

Description

[Zac Cross]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2a) Gecko/20020910
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.2a) Gecko/20020910

In the page at www.touchmyemo.com, if I am downloading a file and my internet
connection fades out (which happens more than I would like) and then comes back
on in a few seconds/minutes Mozilla's downloading manager fails to resume.  I
click the pause and resume buttons but nothing works.  This isn't a problem in
Internet explorer because you can hit cancel and hit download again and it will
pick up where it left off.  However, in Mozilla because the file already exists
(smaller than what the complete file should be) you have to overwrite and start
again.
If I try to just disconnect the network in order to see if it does the same
thing the file just considers itself finished.

Reproducible: Always

Steps to Reproduce:
1.you will need to go to one of the downloading pages such as :
http://touchmyemo.com/music/musicdir2.php?dir=Albums/Thursday//Full%20Collapse/
2.Once there right click on a file and click "Save Link Target As"
3.I don't know how to reproduce the part where you have a **** internet
service provider but the LAN that I am on is not very good and will just stop
responding for minutes at a time.  I attempted to just disconnect it and see if
that would reproduce it and it does not.  
Actual Results:  
After the internet goes out and comes back the downloads are still showing the
percentage, the time remaining and the kb/s.  However, it is not moving nor is
any progress being made.  They will remain like this until I start the downloads
over and rather than resume from where they were they start over.

Expected Results:  
It could do one of two things.  Either have the capabilty to resume
partial/failed downloads like internet explorer does (by not writing the file
name until it is completely downloaded), or force it to automatically check for
internet connection and resume after say 1 minute or 5 minutes.

I have the same (or very similar) problem with 1.2.1: Please, I'm a new
bugzilla.mozilla.org user, so forgive me if I don't even attempt to change any
of these options I see above.
Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.2.1) Gecko/20021130
If I download a file and, midway, quickly pause and resume, it carries on. If I
disconnect the LAN and plug it back in quickly, nothing goes wrong (I have a
feeling that TCP/IP would fix this bit and interpret the break as lost packets
which need to be resent). If I click on pause and close the download window and
open it again, the pause button is there, as if I never paused it. If I press
pause (or resume after I've pressed it again), nothing happens. I have noticed
that the only indication that still works is the timer, which still adds up the
time since I pressed resume. But I have absolutely no indication (in the dialog
window or Download Manager) whether or not it is downloading anything.

I'm changing the subject to auto-resume since resuming of failed downloads 
already exists (bug 164878)

BTW: Auto-resume was mentioned as one of the alternatives in the first 
comment. I'm not going commando here. :-)

Running WinXP SR1, Mozilla 1.2.1 - problem persists as described by Brendan Hide
 2002-12-03 above. When Download Manager is opened again, all files are said to
be completed and show this in window. However, actual file is not complete (when
viewed in Explorer).

Same problem as described in comment #5 exists in Mozilla 1.3: 
Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.3) Gecko/20030312.

This bug makes it impossible to pause a download, hibernate the laptop and
resume the download when the laptop is resumed.

However, I remember that some time ago I was able to resume the download by
switching Mozilla to Work Offline mode and then back to Online mode again. This
somehow tricked Mozilla to resume the download as nothing had happened. I do not
remember the exact procedure for this trick.

Okay, I came to this via bug 164878 - then I saw that it referred to bug 18004,
of which this one is clearly a dupe.  (Although it's not very encouraging that
that bug was filed in '99!)
