279294 - faulty automatic rename after duplicate download

Status: RESOLVED DUPLICATE of bug 231048

(Toolkit :: Downloads API, defect)

Description

[Nathan Walp]

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

If a file is downloaded that ends in a '-' followed by a number, and then that
file is downloaded again, the second copy is automagically saved as
file-(number+1).exe rather than file-(number)-2.ext like you would expect.  This
can be especially dangerous if that number is actually a date, so what was once
foo123-20040709.zip is now foo123-20040710.zip.

This may be related to bug 236514, but that is about overwriting the file, where
as this is about badly renaming it.

Reproducible: Always

Steps to Reproduce:
1. Download a file ending in '-' followed by a number
2. Download the same file again

Actual Results:  
foo123-20040709.zip was downloaded, and then downloaded again, but saved as
foo123-20040710.zip.

Expected Results:  
It should have downloaded one copy as foo123-20040709.zip, and either prompted
about the second copy, or downloaded foo123-20040709-2.zip

My download manager is set up to automagically download everything to the
desktop, and not to hide itself after completion.
