Fix issue #220: sdelete 2.0 is too slow

[jpmat296]

Back to SDelete 1.61 thanks to archive.org URL

I don't know if some people would prefer to stay with sdelete 2 since it seems sdelete 2 works well for them.

I've used this diff/fix and can confirm that it works.

Even with this change, my build still crashes :(

Any ideas?

@discentem please post more of your log. It indicates that sdelete.exe was not present in c:\Windows\temp, but without earlier messages one cannot see why.

[discentem]

@petemounce of course I can't get it fail in the same way again. failed in the above fashion 3 times this morning but not now.

[discentem]

@petemounce It failed again due to sdelete. Here's the full log:

The line that fetches the sdelete zip file

if not exist "C:\Windows\Temp\SDelete.zip" (powershell -Command "(New-Object System.Net.WebClient).DownloadFile('http://web.archive.org/web/20140902022253/http://download.sysinternals.com/files/SDelete.zip', 'C:\Windows\Temp\SDelete.zip')"  0<NUL )

is now fetching some HTML rather than the zip file. Using the web archive is inherently quite a brittle way of fetching a dependency, since the behaviour of the URL may change, like it has here.

If you change the line so it downloads http://web.archive.org/web/20140803110527if_/http://download.sysinternals.com/files/SDelete.zip that should work - until the next time it doesn't.

Closing this, we should use another tool instead of depending of no longer available downloads. A PowerShell native solution mentioned in #220 (comment) would be better.
