Subject Re: [VOTE] Apache HAWQ (incubating) 2.0.0.0-incubating Release
Date Tue, 09 Aug 2016 02:40:05 GMT
Hi Justin!

sorry for a belated reply -- I was on a glorious 2.5 vacation with a
total disconnect from
my email/etc (I have to admit I did Tweet a bit, but only when it came
to non-software
related things like politics or beer). And speaking of beer -- we
really owe you a big one.
I hope you're coming to ApacheCON EU!

Now, I see that HAWQ community captured the majority of your feedback with some
pretty good JIRAs (which are currently blockers for 2.0.0.0) release.
What I wanted to
do, though, is to provide some additional context so that two of us
(and the rest of the IPMC)
can be on the same page wrt. where HAWQ is coming from.

What makes HAWQ code base unique among Incubating projects is that it
contains a lot of
source code (lifted verbatim) from PostgreSQL and Greenplum Database
(the former licensed
under the BSD-derivated license and the later under the ALv2). Not a
problem in principle,
but a source of great many questions for which there's not a huge
amount of prior art in the
incubator. By the way, as an aside, I must say that given your
analysis even the inclusion
of an ASF project source code (thrift) proved to be problematic, let
alone inclusion of non-ASF
code.

This is why we're relying a great deal on RAT's exclusion file to mark
the files that came
from PG even though their license headers could look weir enough. E.g.
your [22] example
     https://github.com/apache/incubator-hawq/blob/2.0.0.0-incubating/src/backend/port/qnx4/shm.c
It is true that the license header doesn't really tell you what the
license is, but since it came
from the PG 8.1.0 release:
     https://github.com/postgres/postgres/blob/REL8_1_0/src/backend/port/qnx4/shm.c
we are trusting the upstream that it is available under the
BSD-derived PG license.

We're currently maintaining the exclusion list via the pom.xml:
    https://github.com/apache/incubator-hawq/blob/2.0.0.0-incubating/pom.xml#L82
and thus we ask folks to run rat as:
    $ mvn verify

Now, if you think we should have a more precise exclusion list (e.g.
get rid of globbing and
list individual files) I'd be comfortable with that (although it will
make the pom.xml quite
large) but if you're saying that we need to slap an ALv2 license
header on something
like shm.c -- I don't feel comfortable doing that. I remember a few
discussion in the past
where this was a recommended position on foreign code coming into ASF.
A recent example
of Kudu, also confirms that. E.g. content of:
   https://github.com/apache/kudu/tree/master/src/kudu/gutil

So I think that the path forward here is to clarify licensing
(especially things like 4 clause BSD license)
but still not touch the original files. Would you agree?

Thanks,
Roman.
