Alex Boisvert updated BUILDR-287:
---------------------------------

    Issue Type: New Feature  (was: Bug)
       Summary: Optionally use destination folder as temporary storage during download instead of using default TMPDIR env variable  (was: buildr should download temporary files to the destination folder, not the temp directory)

If you guys don't mind, I'm rewording this as an enhancement request rather than a bug.    Using TMPDIR is fairly standard and I think the right thing to do by default.

> when downloading artifacts, BuildR first downloads to a temporary file in the temporary directory (/tmp) and then moves the file to the repository location (Generic#download in transports.rb). 
> In many unix systems, /tmp is a separate mount from /. This creates two drawbacks:
> 1. if there is not enough space in /tmp, the download fails (this happens to us many times, and during a nightly build)
> 2. moving files between partitions is actually copy and delete
> If instead, BuildR will download the file to the directory in the repository and then rename to the actual file name, these problems will be solved. 
> The fix is to use
>     Tempfile.open File.basename(target), File.dirname(target)
> When creating the temporary file for download
