Frequently Asked Questions about CNRI's legal policy regarding
|
||
|
|
contributions to Python
|
||
|
|
|

If you have a question that isn't answered here, please write

Q. What are the legal requirements for contributions to Python?
|
||
|
|
|
||
|
|
CNRI's lawyers recommend that we collect legal agreements for all new
|
||
|
|
contributions. For small contributions, a simple two-paragraph note
|
||
|
|
in the email containing the contribution suffices (see
|
||
|
|
bugrelease.txt). For more substantial contribution, we require a
|
||
|
|
mailed signed copy of a simple form (see wetsign.txt). We have tried
|
||
|
|
to make the legal language as simple as possible.
|
||
|
|
|
||
|
|
Q. Why does CNRI require this?
|
||
|
|
|
||
|
|
In order to make it possible to protect Python against potential
|
||
|
|
infringements. Other organizations that distribute free software do
|
||
|
|
the similar things; for example, the GNU project requires a much more
|
||
|
|
strongly worded form, assigning all copyrights to the Free Software
|
||
|
|
Foundation, for all contributions to GNU software.
|
||
|
|
|
||
|
|
Q. When is a contribution small enough to require only an email note?
|
||
|
|
|
||
|
|
This is determined by us on a per-contribution basis. Up to 20 lines
|
||
|
|
of patches typically qualify as small; however if you manage to do
|
||
|
|
something truly spectacular in 20 lines or less we may ask you to send
|
||
|
|
in the signature form anyway.
|
||
|
|
|
||
|
|
Q. I have contributed to Python in the past. Should I sign and mail
|
||
|
|
in a form now?
|
||
|
|
|
||
|
|
Yes, please. We are in the process of getting wet signatures for all
|
||
|
|
major contributions to Python up to now. If you contributed a module
|
||
|
|
or more, we'll try to get in touch with you; you can save us the
|
||
|
|
effort and mail us the signed form right away!
|
||
|
|
|
||
|
|
Q. Do I have to accurately list everything I contributed?
|
||
|
|
|
||
|
|
No. If you made multiple contributions in the past, it is sufficient
|
||
|
|
to write in the form under "description" something like "everything
|
||
|
|
I've contributed until <date>." If you continue to make
|
||
|
|
significant contributions in the future, you can send us an update
|
||
|
|
form using a similar formulation every once in a while.
|
||
|
|
|
||
|
|
Q. Can I send in a form to cover all my future contributions?
|
||
|
|
|
||
|
|
No. However it's okay if you send in a form, say, once a year,
|
||
|
|
covering all your contributions from the last time you sent one in
|
||
|
|
until the date you sign the new form.
|
||
|
|
|
||
|
|
Q. Does the form protect me against copyright or patent infringement
|
||
|
|
suits?
|
||
|
|
|
||
|
|
If you infringe somebody's rights, no form in the world that you sign
|
||
|
|
can protect you. The form only protects CNRI, because the act of
|
||
|
|
collecting the forms shows that CNRI is doing "due diligence"
|
||
|
|
regarding asserting the origin of contributions.
|
||
|
|
|
||
|
|
Q. Does the form protect me against claims from damage resulting from
|
||
|
|
use of my contribution?
|
||
|
|
|
||
|
|
We have reluctantly added a paragraph wherein you disclaim all
|
||
|
|
warranties etc. You may see this as some form of protection. However
|
||
|
|
the law regarding such disclaimers is complicated and varies widely
|
||
|
|
between states and countries, and the particular disclaimer used on
|
||
|
|
the form may not cover you in all cases.
|
||
|
|
|
||
|
|
Q. Does the form transfer my copyrights to CNRI?
|
||
|
|
|
||
|
|
No. CNRI only gets certain non-exclusive rights. See the form for
|
||
|
|
the exact list of rights.
|
||
|
|
|
||
|
|
Q. If I don't sign, will my past contributions be removed from Python?
|
||
|
|
|
||
|
|
That is up to CNRI's lawyers to decide.
