std.file.rename throws on Linux (uploader example)

Posted Mon, 15 Oct 2012 00:20:19 +0200

Hello again!

For me, the uploader example doesn't work. After trying to upload a plain text file from my home directory, I get this:

500 - Internal Server Error

Internal Server Error

Internal error information:
std.file.FileException@std/file.d(512): ./plain.txt: Invalid cross-device link

This probably has something to do with rename() not working between different mount points on Linux. I'm not sure how it can be fixed, except manually copying the file and deleting the old one?

Thanks, Matej
