269531 - Cannot download large files >4GB

Status: RESOLVED DUPLICATE of bug 243974

(Toolkit :: Downloads API, defect)

Description

[Wesley Miaw]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.5) Gecko/20041107 Firefox/1.0

I attempted to download an 8GB DVD ISO and a 4GB DVD ISO (file sizes reported
via command-line FTP are 8052670464 and 4455045120 respectively). Firefox
reported both downloads as complete at 4GB (when the negative counter counts to
zero). According to Microsoft's Windows XP NTFS doc, the maximum NTFS filesize
is "Implementation: 16 terabytes minus 64 KB (244 bytes minus 64 KB)"

Reproducible: Always
Steps to Reproduce:
1. Download a file larger than 4GB.
2. Wait for it to complete.
3. Note the incomplete filesize.

Actual Results:  
Firefox reported the download complete but the file was not the full size.

Expected Results:  
Downloaded the full size file, or if the filesystem doesn't support it, report
an error.

Not a dupe, since >4GB incomplete is not same case as >2GB (with negative
download values). Will have to look into this further. Thanks timeless.

bug 243974 comment 1 : "probably httpchannel truncates the content-length to
32bit, and stops reading from the socket after having read the truncated number
of bytes?" (bug 243974 is fixed on trunk, but not the branch).

Please reopen if you disagree. You can grab a nighlty trunk build to try it out.
