agree with Warner that I know of few if any cases where copyright was not
maintained when it was in the code itself. And as he points out, please
grep through the archives and I think that will be found to hold true.
But I also think Rob rankle comment is fair. Joy and was noted for
recognizing cool ideas and adding them into 'Berkeley UNIX. The line at
the time was he took ideas and '*peed on them to make them smell like
Berkeley*.' For example, 'Berkeley Joy Control' came from Kulp via Europe
and MIT, the network stack famously started at BBN, and a lot of the
support for limits and user controllers from Australia.
Yes, the CSRG team did do a great deal of innovation as well as
integration, but the line between the two was not always easy to see from
the outside.
Well, there can be a huge spectrum here, isn't there? Ranging from:
* Take the code wholesale with no changes.
* Take the code and make changes to match with local coding style.
* Take the code and serially rewrite it so when you're done it
only vaguely resembles the original contribution.
* Look at the code, get the ideas, and the reimplement it from
scratch, keeping the existing interface (or using the existing
interface as a starting point before extending it)
* Look at the code, get the ideas, and reimplent it from scratch
with radically different interfaces.
It sounds like all of these were used to some extent as part of the
BSD/CSRG integration process; is that right?
