Unversioned distfile cached on distfiles.macports.org

[Gregory Anders]

Hi all,

I maintain the netdata port which includes a subport for the web 
dashboard. This subport's distfile is called simply "dashboard.tar.gz", 
with no version number in the name. The distfile is cached by MacPorts 
at https://distfiles.macports.org/netdata. The problem I'm having is 
that when I try to increment the version number of this subport MacPorts 
is still downloading the distfile from distfiles.macports.org rather 
than the updated file from GitHub.

What is the proper way to handle a situation like this? Can I somehow 
tell MacPorts not to cache this file? Or can I add something to the 
Portfile that indicates that MacPorts shouldn't try to download the 
distfile from the cache?

Thanks,

Greg
