Licensing of package nauty

2008-01-24 Thread bremner

Nauty [1] is pretty much the standard software for graph isomorphism
testing, and is used by a several other pieces of research software
(e.g. polymake, which I have ITPed [2]).  Unfortunately from the
Debian point of view, the distribution conditions are somewhat
restrictive.

I can ask the author if would distribute under some DFSG free license,

needed before it can be included in non-free?

 I'll reserve judgement until we can know that this claim of retain
 copyright is not all-inclusive.

Well, as ever in these cases, clarification from the copyright holder
would be the best way to be sure of the position. But the more I think
about it, the more I think retain copyright means what it says -
i.e., keep something you already have, not obtain something you didn't
previously have.

This does illustrate yet again one easily-overlooked problem with
licence proliferation and ad hoc licensing terms for free software -
namely, that a lot of these non-mainstream terms are very poorly
drafted.

This looks like it gives us permission to distribute it in non-free if
you can get it licenced under a DFSG-compatible licence.

This is totally non-free, alas. It does not allow for modification of
the software, prohibits commercial sale (thus making it impossible to
distribute as part of a Debian DVD or CD set) and contains a serious
use restriction (against nontrivial military significance, whatever
*that* means).

 You must
 not remove this copyright notice, and you must document any
 changes that you make to this program.

That bit's OK.

 This software is
 subject to this copyright only, irrespective of any copyright
 attached to any package of which this is a part.

I'm a bit unclear as to what this means. The author seems to think
that the notice itself is the copyright, so when he says the subject
is subject to this copyright only, I assume he means subject to
this copyright *notice* only. That's probably OK, though it could
cause some compatibility problems if combined with GPLed software.

 I can ask the author if would distribute under some DFSG free license,
 but in the case that he declines, is there any other clarification
 needed before it can be included in non-free?

I don't think any clarification is needed for inclusion in non-free,
assuming that the no sale for profit wording is OK for non-free.

 This is actually a very intriguing question. If I have a shell account

 Can I now demand the source to /bin/ls from the administrators of 'toad'?

That is indeed an intriguing question. Within the GPL language of
distribution, it's probably a little unclear. However, GPL v.3 would
appear to be a little tighter on the issue:

-
To propagate a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy. Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.

To convey a work means any kind of propagation that enables other
parties to make or receive copies. Mere interaction with a user
through a computer network, with no transfer of a copy, is not
conveying.
-

It seems clear enough that the administrators of toad are
propagating /bin/ls. And that propagation is one that enables
other parties to make or receive copies. Nor is this mere
interaction ... with no transfer of a copy - *running* /bin/ls would
fit this category, but making a copy of /bin/ls in your home directory
is a different matter.

So this would seem to be conveying within the meaning of GPL v.3,
and thus will fall within clause 6 of GPL v.3, Conveying Non-Source
Forms.

That does sound a bit excessive, I agree. But it's difficult to see
how this can be avoided, unless you make it impossible to transfer
files from users' home directories on toad to their own local systems.
If you were to do that, then arguably no conveying would occur as an
copying would be done on a remote system as mere interaction over a
computer network. But I'm guessing that prohibiting file transfers in
this way would create rather more problems than it would solve!

A contrary interpretation - that this is not conveying - would leave
a massive loophole in the GPL, because you could say, We are not
going to distribute our modified software directly. No, instead we're
going to give people shell access by which they can then copy the
software to their remote home directory and thence to their own local
system.

That said, I would be *delighted* if someone can show me where I've
gone wrong in my analysis. I don't claim to be a world expert on GPL
v.3!

 Maybe having a deb-src line is good enough since users can run apt-get
 source?

Clause 6(d) of GPL allows the source to be made available in this way,
so I assume that would be fine. However, you would need to ensure the
relevant details were given next to the object code, whatever *that*
means (a README for every affected file in /bin? i.e. /bin/ls.README
etc? ***shudder***).

License compatibility with GPLv3

2008-01-24 Thread Miriam Ruiz
Hi,

I have some small problem with Gnash that might be extensible to other
packages, so I'm asking here to find out if anyone else has had that
problem too and how did they manage it.

Gnash is GNU's free Flash player. It is now licensed under GPLv3 (it
was previously GPLv2 or above). It has a really huge list of build
dependencies:

dpkg-dev (= 1.13.19), debhelper (= 4.0.0), quilt, autoconf, dh-buildinfo,
automake1.9 | automake, libtool, libltdl3-dev, help2man, libxmu-dev, dejagnu,
autotools-dev, libboost-dev, libboost-thread-dev, libxml2-dev, libjpeg-dev,
libpng12-dev | libpng-dev, libagg-dev, libgstreamer0.10-dev, libkonq4-dev,
libpango1.0-dev | pango-devel, libgtkglext1-dev, libmad0-dev, libdirectfb-dev,
libcurl4-gnutls-dev | libcurl3-gnutls-dev | libcurl4-openssl-dev |
libcurl3-openssl-dev,
libcaca-dev, libboost-date-time-dev, libavcodec-dev, libavformat-dev,
libming-dev,
libming-util, mtasc, libgstreamer-plugins-base0.10-dev,
libboost-serialization-dev, python, base-files (= 4.0.1)

All these dependencies already have their own list of dependencies
too, right now I'm concerned about libkonq4-dev and Qt being GPLv2
only. Even though all of these packages might be GPLv3 compatible, it
is not guaranteed that their dependencies are, like:

Package A (GPLv3) depends on package B (GPLv2 or above)
Package B (GPLv2 or above) depends on package C (GPLv2 only)

Both dependencies would be OK on their own, but I'd be effectively
linking A (GPLv3) with C (GPLv2 only) which are not compatible.

As you can imagine, the work of checking all the dependencies by hand
would be enormous. I could check the dependencies of the resulting
binary packages instead, but I'm not sure if that would be enough (or
I should check their dependencies too), would it be?

Any ideas?

Greetings,
Miry

Perhaps a simple way to avoid this is to simply 'chmod g-r' the
executables in question. With only execute permission a mortal user
cannot copy the binary, so there's no propagation going on.

If the system has a world-readable /usr/src with full sources, I 
would argue that satisfies any obligation to make source available.

You could always point them in the direction of the Debian policy at

If they don't give a satisfactory answer then that's a matter for SPI

As outlined previously in the discussion, I don't think there *is* a
loophole here. Anyone using GPL v.3 software (which includes almost
all GNU software issued since GPL v.3 was introduced) to provide
remote shell access appears to be bound by GPL v.3 to provide the
source, whether they have modified that software or otherwise. 

At least, that's my take, and no-one has yet put forward a

So there is no loophole, but equally there is probably a very high

In the absence of that, it does seem the only way to know is to

Thanks. The distinction here is that in the classic ASP loophole
situation you are accessing the software through a web browser or
other intermediary means, which prevents you from getting direct
access to the executable: it is mere interaction over a computer
network, with transfer of a copy, as GPL v.3 puts it. 

A remote shell is a different matter. This isn't just access through a
web browser; it is direct access to the executable in a manner not
wildly dissimilar to accessing a local file through a shell, and
indeed access in a way that will usually allow the user to create a
copy of the executable either on the remote system and/or their local
system.

Hence the first scenario, if considered to be a problem requiring a
solution, leads to the Affero GPL. The second scenario is, I would
argue, already covered by the regular GPL.  

(Incidentally, I'm assuming that the earlier suggestion of removing
the read permissions for users wouldn't work, because they wouldn't be
able to execute the binaries without read as well as execute
privileges. Is that correct?)

$ ls -l /bin/ls
