Status: RESOLVED DUPLICATE of bug 184452

(Toolkit :: Downloads API, defect)

Description

[Zbynek Novotny]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.6) Gecko/20060728 Firefox/1.5.0.6
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.0.6) Gecko/20060728 Firefox/1.5.0.6

Sorry if this has been reported, but the only bug mentioning 2GB limit was referring to a badly displayed size.

The problem I have encountered, however, causes downloads larger than 2^31 - 1 to be stopped and marked as complete. I tried to download Windows Vista ISO image twice today from the official site (which had already been closed earlier today, unfortunately), but in both cases the download stopped after 2 147 483 647 bytes were received, and the popup window showed up saying that the download was completed.

Reproducible: Always

Steps to Reproduce:
1. Try to download anything larger than 2^31 bytes and see if you get this behavior.


Actual Results:  
The file was marked as downloaded after the "limit" has been reached.

Expected Results:  
Successful completion of the download when _all_ the data were received.

no, not a dup of that bug

This is actually supposed to work, at least since bug 340956 was fixed. You used FF 1.5.0.6 for that?

Yes, I checked the version of my copy of the browser just before I decided to file this bugreport.

hrm... are you downloading to a FAT32 or NTFS filesystem?

Comment 5

[Zbynek Novotny]

The latter.
