784066 - Download Manager says it downloaded a file with the (large) anticipated size, when in fact it got a 0-byte file

Status: NEW

(Toolkit :: Downloads API, defect)

Description

[Daniel Holbert [:dholbert]]

STR:
 1. Download this file (e.g. by clicking this link and picking a save location):
     http://nightly.webkit.org/files/WebKit-SVN-source.tar.bz2

   ---> At the moment, the download will fail, and will just
        produce a 0-byte saved file on your filesystem. BUT:

 2. Inspect the download notification that Firefox pops up.

EXPECTED RESULTS: Firefox reports that the download fails, and/or reports that the saved file was 0 bytes.

ACTUAL RESULTS: Firefox tells me that it (instantly) downloaded a file of size "1.8 GB"


(NOTE: I haven't been able to download the Webkit tarball with any browser / download manager for the last couple days, so I suspect their server is temporarily misconfigured or something. Whenever they fix it, this bug probably won't be reproducible at that URL anymore.)

Attachment: curl output

Here's the stderr log from attempting to download the file with "curl -vvv", in case it helps.

Note that curl ends by reporting...
>  curl: (18) transfer closed with 1916464829 bytes remaining to read
...which correctly tells me:  "Uh oh, I expected 1.8 GB more data than I received"

(contrast that to Firefox's download manager UI, which implies that it received all 1.8 GB of data)
