Re: [PATCH] Add dcfldd

[Andreas Enge]

Hello,

I did not give it a try, but the package looks generally good to me.

This should be something starting with
   mirror://sourceforge/
potentially
   mirror://sourceforge/dcfldd/dcfldd/1.3.4-1/dcfldd-
(I always try it out). Maybe you could also string-append once more with
the version to get rid of the middle "1.3.4.-1" and make updates easier.

Hm, I wonder about the political question whether as the GNU system, we
should package forks of GNU software. (The authors are also rather
suspicious...)

Since you created this file, it should only be copyrighted by you.
Also, it seems that the patch has been munged by your mail client.

* Although the content is in UTF-8, the mail headers say it is encoded
  in windows-1252, so the non-ASCII characters are all corrupted.

* It has been word-wrapped, so it's no longer a valid patch.

Maybe try sending the file as an attachment instead?

As Andreas mentioned, this URI should use Guix's "mirror://" syntax so
that it automatically chooses from several known mirrors.

Is the license really gpl2 and not gpl2+?

Thank you, will fix.

Speaking strictly for myself I find both the progress indicator and the 
speed improvements extremely useful features.

I would also hope we are willing to accept all useful free software, 
regardless of provenance, for inclusion in Guix.

Mark,

Thanks for comments on technical points. I'll fix the mirror link and 
re-mail the patch with mutt.

> Is the license really gpl2 and not gpl2+?

re: Licensing, my impression was that "gpl2+" only applies if the 
authors specifically invoke "any later version" when they distribute the 
software, per clause 9 of the GPL 2

"9. The Free Software Foundation may publish revised and/or new versions 
of the General Public License from time to time. Such new versions will 
be similar in spirit to the present version, but may differ in detail to 
address new problems or concerns.

Each version is given a distinguishing version number. If the Program 
specifies a version number of this License which applies to it and "any 
later version", you have the option of following the terms and 
conditions either of that version or of any later version published by 
the Free Software Foundation. If the Program does not specify a version 
number of this License, you may choose any version ever published by the 
Free Software Foundation."

Upstream lists the project as:
"License
GNU General Public License version 2.0 (GPLv2)"
http://sourceforge.net/projects/dcfldd/

Am I in error?

In some cases the "or later" clause is only mentioned in the source file
headers.  I see, from a brief glance at the source, that this is the
case for dcfldd.

Yes, that’s always been the case.

Though in general it’s nice to entice authors of forks of GNU packages
to get them merged back, if they haven’t tried already.

Thanks,

I believe the copyright notices in the source files are ultimately what
determines the license.  If the source files include copyright notices
with the "any later version" language, then the license is in fact
gpl2+.  This is also my expectation given that 'dcfldd' was forked from
GNU dd, which was presumably covered by gpl2+ at the time of the fork.

     Thanks!
       Mark
