I'd have hoped we wouldn't have to be responsible for that. While we could 
search for the copyright banner in files, I can't guarantee every file 
contains a Red Hat copyright that should have (even from the days when 
we^H^HRed Hat were working on eCos). And for the files without a Red Hat 
copyright banner, it would need careful identification to work out whether 
they are Red Hat's or someone elses (or indeed are mostly someone elses but 
may contain portions of RH code thus making it a derived work). The 
consequences of us making a mistake with the identification is painful; but 
if Red Hat makes the mistake it's nowhere near as bad and I believe intent 
does matter a lot in these circumstances.

It would be much much nicer if Red Hat could arrange some sort of blanket 
assignment, perhaps just by reference to the contents of the entire eCos 
CVS repository at ecos.sourceware.org. Or perhaps just list every 
repository file, irrespective of copyright and finetune the wording of the 
assignment so that it assigns any right and title that _may_ belong to Red 
Hat in the listed files. I'm no lawyer though.  I'd be more than willing to 
talk to them about ways it could be done though..... if they'll talk to me!

Should we propose what the new banner looks like?

Is the basic format of the current banner  OK?

The last bit clearly wants to go since its not been true for a long
while.

Should the original RedHat Copyright line be deleted as well? I guess
leaving it could confuse people into thinking the files are still
copyright RedHat as well as being FSF..

Hmmm, this is of concern. I thought all of eCos could be attributed to 
either Red Hat, eCosCentric or one of the maintainers.  Are you saying 
that there are files that are not copyright one of the above?

If there are files that do not have a copyright banner from their owner 
(Red Hat or otherwise), then would you also not have to get consent from 
the owners also on the assignment to the FSF.

IMHO this is not going to happen unless somebody outside Red Hat drives 
this.  I suggest getting a draft together for all maintainers, Red Hat 
and eCosCentric representatives to sign that simply states that they 
assign copyright to all the files for which they may hold copyright in 
the ecos CVS repository to the FSF.

Come to think of it, my previous suggestion of listing the files is not 
a good idea as there is no guarantee that the list will not change while 
we are waiting for signature.  You will have to freeze contribs while 
waiting for signatures which will be could be forever in the case of Red 
Hat.

We could approach Red Hat with a formal written offer to do this so that 
the assignment to the FSF which they announced can actually take place. 
  If you want help from me, let me know.

I'd like it to be changed actually. Some of the information parts of the 
banner are _very_ frequently poorly maintained and/or inaccurate and do us 
a disservice. I think the Authors/Contributors bits are ambiguous; and the 
Purpose/Description ditto. It's never really been clear what Date the Date 
is for. I think I fill these in more than most people, but still rarely. 
Contributions very frequently have inaccurate fields here, most annoyingly 
the author.

I think something like the following fields would be better/clearer:

Maintained by: <person responsible for _this_ file, irrespective of what it 
was derived from>

Contributors: <anyone else who's worked on it and wants a mention>
Derived from: <what file/package it was derived from if relevant
Description:

I propose dropping the date entirely partly due to the ambiguity and partly 
because it doesn't tell us anything we can't find out more accurately from 
the changelogs.

I propose dropping the mini-description underneath the filename at the top, 
as it is usually no better than the description further down.

It would require some cunning script-fu to try and squeeze the content 
there now into this style as best as possible, but it would be good to do 
these types of sweeping changes that touch all files once. Of course plenty 
of the existing content is wrong too, but we can fix that piecemeal. For 
example most of the "Maintained by" headers would be filled in on a package 
-wide basis.

Absolutely. We just didn't want to touch every file multiple times. People 
doing "cvs update" won't like us otherwise :-).

When the assignment is properly made the RH copyright _must_ disappear in fact.

I have a script that munges file headers, that was used in the RHEPL->GPL 
change and other changes before that. It's horrible as it has evolved 
piecemeal over time so it's a real hacky mess so I don't want to publicise 
it here :-). It deals with all the various comment characters ( /* */ 
versus // versus # versus ; versus dnl versus <!-- -->) and differing 
licenses though (BSD stack, host tools, etc.) IIRC.

A perl wizard may be able to do a better job quite quickly though, 
especially if we're to munge the other header fields too - this is one of 
the things perl is good at.

My idea was no he wouldn't... "Maintained by" would be how maintains it 
now. Historical info is something for ChangeLogs and cvs logs, not banners, 
and not when it's no practical use.

Of course in your example someone would eventually have to clean up that 
file (unless the script explicitly watched for user dsm - there aren't that 
many names mentioned). There would probably want to also be a NO-MAINTAINER 
thing for something which no-one is claiming. That of course will help 
people realise where bit-rot is, so this in itself is useful too.

No, I mean there are files which don't explicitly have a banner saying who 
owns the copyright, so it makes it difficult to use the copyright banners 
as a method of determining fully which files Red Hat needs to assign.

Maybe, but it becomes silly if the sole point of the exercise is that it 
all ends up as Copyright FSF and nothing else. Since we know that all the 
copyright is held by RH, eCosCentric and the maintainers it's naff if 
things have to be held up to work out some bureaucratic list; hence my 
suggested possibly viable alternatives.

As soon as the FSF starts replying to my mails! There's still the issue of 
the publically stated "guarantee" we wanted from them not to immediately 
strip away the GPL exception. It looked like we were very close to agreeing 
this - it just all went very silent that's all. Right now I know that the 
FSF is not accepting assignments for eCos. Any agreement will have to be 
reviewed by either or both of the RH and FSF legal counsels I'm sure, and 
probably constructed by one of them.

It's more a question of getting a dialogue with anyone. I'm sure whatever 
the issues are we can work them out; but if we can't even start discussing 
them we're no further on.

I wonder, in all seriousness, if we (or some of us) chipped in to a 
donation to the FSF so we can say "Talk to us and we'll give you a 
donation.". I wouldn't have thought it would be too difficult to rustle up 
$150 or so given the current exchange rate. Maybe eCosCentric would like to 
chip in too :). I'm willing to contribute personally anyway, just to give 
myself some peace from this palaver!

Yup, gladly, anything to move this along as we waste a lot of time with 
the problems of them not doing the assignments and getting the RH 
assignment sorted out.

When the books for 2003/2004 close we can see what is left for 
donations.  $150 should be doable, if only we could guarantee that it 
would make the FSF listen...

Hi -

Sorry to bud into this old thread.  I gather that one reason for
the Red Hat assignment delay is to identify those files related
to RedBoot, and to exclude them from the process.  I don't know
this plan's novelty or rationale or degree of official blessing.
