Corinna,
Maybe the "Before you get started" section in [1] should mention Signed-off:
and what we think it means?
That's a good point.
dll.html is outdated. We don't use the CONTRIBUTORS file anymore. It
was a remnant of the past, when we switched our license and we still
needed to keep track of the developers and the 2-clause BSD rule while
long-living contracts with the old buyout license were still active.
On second thought, I think we should rename the file to
PAST_CONTRIBUTORS and prepend some lines that we switched to the
Developer Certificate of Origin, pointing to dll.html...
These days, I would like to enforce the Signed-off-by: line and it
should have the same place and same significance as in the Linux kernel,
that is...
https://developercertificate.org/
Briefly, the sign-off means, that the contributor has, both, the right
and the willingness, to contribute code to this project under the
project's open source license, i.e., GPL v3+ in case of Cygwin.
Add that to CONTRIBUTORS.
If we really want it to be mandatory, I guess I could explore the
possibility of a push hook to enforce that?
[1] https://cygwin.com/contrib/dll.html
...and dll.html should be written anew from the pararaph starting
with "If your change is going to be a significant one"... by just
stating that we expect a Developer Certificate of Origin per
https://developercertificate.org/, i.e., a "Signed-off-by:" line
per patch.
That site is about Linux Foundation contributors, so I think we may credit it,
but add the relevant or modified paragraphs (especially licensing) to our
CONTRIBUTORS and/or dll.html, with any conditions and limitations for newlib
contributions and tree, and cygwin-patches contributions and winsup tree.
Does that sound about right?
Yeah, but there's one twist: We don't and can't enforce Signed-off-by:
lines in case of contributions to newlib. Newlib is not under GPL.
Rather it's a collection of multiple open source licenses. So in case
of newlib the meaning of a signed-off is rather fuzzy.
Therefore we only can enforce contributions to Cygwin code and docs.
Document what licence statements (or give source prefix example files) need to
be at the top of new files added under each tree?
