Nathann Cohen seems to have written:

Then there was some bizarre banter starting with "It committed suicide

True.  As there should be.  Contributors keep their copyright.
Authors should get as much and as explicit of credit as we can
possibly give them.

 People probably don't remember the early days of Sage, but there was
often a belief that the project would be *impossible* due to the math
culture in which authorship had to be clearly maintained.  Many people
sincerely thought that the GAP or PARI developers would be very angry
that their system was used in Sage, and that people wouldn't
contribute since their contributions wouldn't be acknowledged.

I don't think we should impose a ton of bureaucracy on the AUTHORS blocks.

However, we should definitely not have reviewers asking people to
remove their names from it, and not removing other people's names
either.

people won't feel like putting their names 
in the AUTHORS block if there is none, or if it is obsolete.
One example is provided by src/sage/graphs/generators/families.py
(featured in the commit above)
 more examples:
sage/combinat/matrices/hadamard.py
 (Only 50% is by wdj, in AUTHORS)

more extreme:
sage/numerical/mip.pyx

(it has Nathann's name in copyright - I guess he cared more about
acknowledgements, as he was still a postdoc, IIRC...)
The only AUTHORS listed is my former student Risan, now at Facebook...

I don't know how widespread this is, absence/incompleteness of AUTHORS.

Probably some automated check should be run,  comparing output of 'git 
blame' with AUTHORS.

Copyright notices are an entirely different topic from this thread. No /

Re: [sage-devel] SPKG Maintainers??

2015-09-22 Thread Kwankyu Lee
I am not that developer :-) 

How about this system?

We trim the AUTHOR blocks by just listing the names of contributors to the 
given module (to give credits to the contributors); 
And we recommend a new contributor to add his/her name to the end of the 
list (to give more credits to the initial creators); 
And this AUTHORS block only appears at the end of the documentation of the 
module (not to clutter the doc for the end users, but still give them 
motivations to contribute).

The incomplete information about "who did what" in the current AUTHORS 
blocks are removed but can be recovered in git.

Re: [sage-devel] SPKG Maintainers??

2015-09-22 Thread Andrey Novoseltsev
I had some random people contact me with questions about the modules I've 
written and I suspect it was due to the AUTHORS block, so it is useful to 
users.

Regarding git, it took me a while to get reasonably comfortable with it and 
while I like it now, it is unreasonable to expect someone to learn using it 
just for the sake of figuring out who wrote what.

And for git blame specifically - it is often ugly when there were multiple 
layers of semi-automated changes in the file and each line has its own 
commit (rather than some logical blocks). Personally I find "History" on 
github for a particular module much more useful than blame display.

It can make sense to add your name when you add something new, but
code is not static like a scientific paper. Contrary to it, code is
modified over time and after a while an authors block does not make
any sense.

The best we can have when it comes to acknowledgement is our trac
server: it stores what each of us did, and this history does not
change. Then we have 'git blame' when we want to know who wrote one
specific line.

With the trac history and the git history, I believe that we have
trustworthy information in both directions.

Authors block, however, are maintained manually and represent more
accurately how we feel with respec to acknowledgement than the
work/sweat we put into it.

You, Jeroen, believe that it is not worth adding your name when you
add a bugfix. If you read the 'authors' block of the graph.py file
(the module, not some specific function) you will see that some people
added their name there after fixing a docstring!

http://doc.sagemath.org/html/en/reference/graphs/sage/graphs/graph.html#graph-format

On the other side of the spectra, Vincent's name and mine appear twice
in the whole combinat/design/ folder, and we basically wrote (or
rewrote) everything that is in there. I spent months for what it is
that folder.

If we start adding our names to authors block at every patch, I will
have to decide whether I want everybody else's name but mine to
appear, or whether I want every single function of the graph/ folder
to have an 'AUTHORS' block with my name on it.

And I will hate myself.

There is nothing wrong with caring about acknowledgements.

I usually add my name as author when I feel that I'm contributing 
something new, not just fixing bugs.


Note that the "git blame" doesn't tell much about the effort that people 
put into the code: usually bugfixes or incremental additions are a lot 
easier than writing the code in the first place. Also, sometimes code is 
just moved around or refactored which completely changes the "git blame" 
output.


I think it's theoretically possible for a person X to be a significant 
author to some piece of code, even though "git blame" doesn't list a 
single line authored by X.

I think that both of the above are correct. So I wild(?) idea...

Could we have some kind of "contact"-chain? Are developers ready to answer 
questions about their code and documentation? Then the point would shift 
from "I made this." to "I can debug or clarify this, if needed."?


I have no specific idea about how to do it. Something like "contact" for 
whole SageMath would be sage-support, then there could have 
sage-partX-support or person X taking care of large part of Sage, other 
would have "responsibility" for sage-partX_1, and lastly there could be 
function level?


An example of chain:

is_supersolvable < lattices < posets < combinat < SageMath

A person writing .is_supersolvable? would get, say, name of somebody 
"responsible" for posets, if there is nobody handling specially just 
is_supersolvable or lattices.


Is something like this done in any software before?

+1 and these facts really speak to a surprising strength of our community.

 I agree let's get rid of this.

 I've updated a bunch of packages but did not feel like filling this
field with my name as I couldn't promise I'll keep on maintaining the
packages.

 Hello,
 
 all SPKG.txt files list SPKG Maintainers. I never quite understood the

 doesn't seem to have a purpose, can we just remove those?

+1

I was wondering why SKPG's have maintainers and other modules do not.

One example would be #16747 (Arb - arbitrary precision floating point ball
arithmetic), where the SPKG Maintainers proposed inclusion in July and we have
not heard anything from them since that time.

I agree let's get rid of this.

I've updated a bunch of packages but did not feel like filling this field 
with my name as I couldn't promise I'll keep on maintaining the packages.
