298783 - Perhaps downloading too many files causes file corruption and

Status: RESOLVED EXPIRED

(Toolkit :: Downloads API, defect)

Description

[Technodreamer]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.0; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

This problem occurs whilst downloading many files at once (Prehaps as many as 15
to 20). I noticed that when I downloaded movie files, if I did a few files at a
time, the files do not become corrupt. However, when I do many at once, the save
as dialogue comes up after a few downloads have completed to download more files
(Almost as though the requested downloads are put into a queue). Afterwards the
files appear to have been corrupted. Upon redownloading them one by one, they
are fine.

Reproducible: Always

Steps to Reproduce:
1. Find a site with movie files that are about 1 meg each. The sites I used are
not appropriate for being mentioned. This should give you some ideas where to
get such files. Lol

2. Make sure FF uses the Save As option, and start right clicking the movies,
and click Save As, and save them. Do this for loads of files. FF allows you to
download two at once to begin with.

3. After it has completed those two, it'll prompt all the rest. So hopefully you
should now have 20 file downloads going.

4. After the downloads have finished, check some of the movies.

5. Now download one of the corrupt files again. Check to see if it works.
Actual Results:  
I observed the following results:

1. The browser uses up lots of memory, however this memory still appears to be
used after the downloads, the browser becomes unstable and the Save As dialogue
appears more slowly each time

2. Some of the resulting files appear to be corrupt

3. Upon downloading some of the corrupt files again, they are not corrupt

4. The corrupt files had unusually small file sizes compared to what they were
meant to be

Expected Results:  
Downloaded all the files at the same time without corrupting them

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
