review. IMO, committer right comes with the responsibility to respect
the
community and policies it established.
I would disagree that rolling back should be used only in case of a
disaster unless PR merge policy violation is a disaster :-) (and it
actually is).

Rolling back, should be used rarely and it does need to be a disaster.
We
need to be cognizant of new contributors worrying about the cost to
submit
code.
I too do not think Apex is hurting from bad code getting in. We are
doing
great with our current policies.

Guess we can all go home then. Our work here is done:
W.R.T the discussion below, I think rolling back an improperly
reviewed
PR
could be considered disrespectful to the committer who merged it in
the
first place. I think that such situations, unless they trigger a
disaster,
should be handled by communicating the error to the responsible party
and
then allowing them to resolve it. E.g. I improperly commit an
unreviewed
PR, someone notices and sends me an email informing me of my error,
and I
then have the responsibility of unrolling the change and getting the
appropriate review. I think we should start with the premise that
we’re
here in the spirit of collaboration and we should create opportunities
for
individuals to learn from their mistakes, recognize the importance of
particular standards (e.g. good review process leads to stable
projects),
and ultimately internalize these ethics.
Internally to our team, we’ve had great success with a policy
requiring
two PR approvals and not allowing the creator of a patch to be the one
to
merge their PR. While this might feel a little silly, it definitely
helps
to build collaboration, familiarity with the code base, and
intrinsically
avoids PRs being merged too quickly (without a sufficient period for
review).

github just decided that this is the best proposal ;)

Ram, committing an improvement on top of a commit should be
discouraged,
not encouraged as it eventually leads to the policy violation and lousy
PR
reviews.

So why not focus on what the committer should do? Development process
and
guidelines are there for a reason, and the issue was raised before.
In this specific case, there is a string of commits related to the
plugin
feature that IMO should be part of the original review. There wasn't
any
need to rush this, the change wasn't important for the release.

we
really
verify the author field and treat it with importance. For

don't
think we ever check if the author is the person they say they are,
check
name, email etc. If I were to use slightly different variations of
my

that.
I
also have checked that tools don't fail on reading a commit
because
author
needs to be in a certain format. I guess contribution stats are
the
ones
that will be affected but if used rarely I dont see that being a
big
problem. I can understand if we wanted to have strict requirements
for
the
committer field.

Consider adding the additional author information to the commit

Please don't use the author field in such a way, it leads to
incorrect
tracking of contributions.
Either have separate commits or have one author.

No, it is not a request to update the apex.apache.org (to

I'd suggest that we stop such practice no matter how

cases
where
PR
is
