Hello Robert,
You're just ignoring explanations from other people - Craig in
particular - about why it DOES satisfy their use case.
I'm not so sure about Craig precise opinion, but I cannot talk in his
name. I think that I understood that he points out that there exists a
situation where the use case is okay despite an untransactional variable:
if the containing transaction is warranted not to fail, and probably
(provably?) a read-only transaction is enough for that. Okay, sure...
This falls under "the feature works sometime", which I think is not
acceptable for a security thing in pg core.
And the reason his argument is valid is because he is questioning your
premise. [...]
Yes.
I made the assumption that PostgreSQL is about keeping data safe and
secure, and that misleading features which do not comply with this goal
should be kept out.
This is indeed a subjective opinion, not provable truth.
I only assumed that this opinion was implicitely shared, so that providing
a counter example with the feature where data is not safe or secure was
enough to dismiss the proposal.
I'm clearly wrong: some people are okay with a security feature proven not
to work in some case, if it works for their particular (read-only) case.
I do not like Pavel's feature, this is a subjective opinion. This feature
does not provide a correct solution for the use case, this is an objective
fact. The presented feature does not have a real use case, this is too bad.
If the presented feature had no use case, I don't think there would be
3 or 4 people arguing for it. Those people aren't stupid.
I have not said that, nor thought that.
I pointed out my arguments, basically I answer "security must always work"
to "the feature can work sometimes". Then it cycles. As I can offer
limited time for reviewing features, at some point I do not have any more
time to argue constructively and convince people, that is life. That is
when I tried to conclude my contribution by sending my review.
[..] Are you also willing to accept other people's differing
conclusions?
I do not have to "accept", or not, differing conclusions. The committer
decides in the end, because they have the power, I just have words.
All I can say is that as a committer I would not commit such a feature.
As a basic contributor, I can hope that the best decision is made in the
end, and for that I try to express arguments precisely and objectively,
that is the point of reviewing a proposal and give advice about how it
should be amended if I think it should.
I believe that the words "silly" and "academic" were used about certain
proposals that you made, [..] it does necessarily imply personal
disrespect.
Sure. "Silly academic" suits me though, I'm fine with it:-)
