225866 - Download progress dialog shows incorrect (or negative) sizes/times and transfer aborts for files 2 GiB or larger

Status: VERIFIED DUPLICATE of bug 184452

(Core Graveyard :: Networking: FTP, defect)

Description

[Joseph Lunderville]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.4) Gecko/20030624

This is pretty clearly an integer overflow problem. Files 2 GiB in size or
larger show up with incorrect sizes (possibly negative). The time estimates and
transfer rate indicator are incorrect or negative as well, once the amount of
data transferred exceeds Mozilla's incorrect trunctated file size.

I have verified that the FTP server is operating correctly.

As a possibly separate problem, the transfer fails after 2 GiB have been
transferred.

Reproducible: Always

Steps to Reproduce:
1. Download any file 2 GiB in size or larger (for example, the test.dat referenced)

Actual Results:  
The file size, time left, and transfer rate displays are incorrect, and the
transfer is aborted after 2 GiB.

Expected Results:  
The file size, time left, and transfer rate displays should show correct data,
and the transfer should complete successfully.

I tried to do the right thing, but didn't find the other bug because the
bugzilla search on the bug submit page doesn't look at resolved - duplicate bugs
(and one of my search terms was "negative"). Sigh.

and it is indeed a duplicate.
