280274 - partially downloaded files are deleted when downloading several big files

Status: VERIFIED DUPLICATE of bug 280272

(Toolkit :: Downloads API, defect)

Description

[debach]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1

I tried to download 2,5GB of data which was divided into 9 files (see
http://www2.onspiele.t-online.de/dyn/c/30/69/26/3069264.html), but Mozilla kept
deleting partially downloaded files from my disk, although I had definitely
enough disk space (about 5GB). The downloads were pretty fast with 100KB/s,
which is almost my maximum. Furthermore, Mozilla didn't cancel the downloads,
for they were still shown in the download manager, it simply deleted the files.
I don't know whether the server stopped sending data, but if so, Mozilla should
still keep the data in order to resume the download later.

This happened twice with three or more files, which were not finished and at
least 50MB at size. I am totally sure that I didn't do anything that could have
cancelled the download or deleted those files. I neither got any error message.
By the way: The progress bar didn't show the % of the download correctly and
neither showed any download progress, but I saw the files growing in my target
directory.

Reproducible: Always

Steps to Reproduce:
1. Download several big files at the same time
2.
3.

Actual Results:  
Partially downloaded files were deleted, but the downloads weren't actually
shown as cancelled.

Expected Results:  
Download the files without deleting them or, if the server doesn't response,
keep the partially downloaded files.
