Subject Re: Commit / Code Review Policy
Date Mon, 02 Dec 2019 08:49:22 GMT
I think the distanse is not necessarily as large as it seems. Nobody wants to get rid of lazy
consensus, but rather put down in writing when we recommend to wait for explicit review.

There have been examples of some rather sloppy and rapid commits in Solr of non-trivial core
code that turned out to cause bugs, corruption and perhaps even security issues. 

Sloppy commit culture (in Solr land) was also one thing Mark pointed out as a major threat
to Solr’s stability and I share this concern. That is what originally triggered the committees
meeting and David’s effort with this document.

I applaude David’s will to try improve the situation and I hope we all can contribute and
be part of the solution. We’re a great team!

Robert, I fully support your RCE suggestions, I.e “looks good to me” which means I don’t
have the expertise to do any better :)

Why should I wait weeks/months for some explicit review? There is repeated RCE happening,
how the hell could I make anything worse?

call out Solr specifics when applicable.  This is easier to maintain and is in line with the
joint-ness of Lucene TLP.  So I think it should move to the Lucene cwiki.  Granted there is
a possibility this kind of content might move into our source control somewhere but that possibility
is a subject for another day.

at will today; we wait for reviews and get them.  I'd like what we do today (in Lucene) written
down more clearly for everyone's benefit -- new/interested people and ourselves.  This document
is my attempt to do that plus raising the review/approval guideline norms just a little bit
(IMO).  For Solr it's more than a little bit, granted.  Then I can point others at this, and
if I see behavior that got no review for something where it was warranted (according to documented
guidelines), I can reference this.
