llvm dev - Sep 2021 - Phabricator Creator Pulling the Plug

All

I'm a massive fan of Phabricator, and I know there is often lots of
contentious discussion about its relative merits vs github,

But unless I missed this, was there any discussion regarding the recent
"Winding Down" announcement of Phabricator? and what it might mean for
us
in LLVM

See:
https://admin.phacility.com/phame/post/view/11/phacility_is_winding_down_operations/
https://www.phacility.com/phabricator/

Personally I'm excited by the concept of a community driven replacement (
https://we.phorge.it/) .
epriestley did a truly amazing job, it wasn't open to public contributions.
Perhaps more open development could lead to closing some of the github gaps
that were of concern.

I think we have our own self-hosted version and enough local people that
has hacked on it to "maintain" it, but we'd stop getting the
updated from
upstream, which have been substantial over the years.

I don't think this should be a rush to replace with an alternative, as
there is no imminent peril, but it is an additional important point for the
ongoing discussion of potential transition.

IMO, it would have to be seriously active upstream, understand our existing
database "as is" and import without problems, and interface with
Github
more closely to be worth the hassle of migration.

Github pull requests don't seem to be improving a lot, so "phorge"
may be
the right answer sooner than they catch up...

As I, and others have noticed, it seems that as of today, there’s some
certificate issue with arcanist. (See:
https://lists.llvm.org/pipermail/llvm-dev/2021-September/153019.html) The fix
seems simple, and a PR is up, but looking through the PR activity, it seems that
the PR will not be accepted because Phabricator is no longer being maintained.
It seems that arc has become the first casualty of the discontinuation of
maintenance of phabricator.

I know that arc is not universally used, but I think it’s a serious blow to many
people’s workflows. I think that MyDeveloperDay’s question might have just
become a bit more urgent.

I suppose in the short-term, we could fork the phabricator repos in order to fix
little issues like this. Alternately, we should probably stop recommending
arcanist (unless we want to provide instructions on how to fix any breakages
that come along).

Thanks,

(replying to my initial email because the thread seems to have gone off on a
tangent)

A long term plan on what to do (migrate to github PRs? Something else?) is
important, but let’s not get lost in the weeds: we have breakages with
phabricator today. I think it’s important to not let our daily workflows degrade
while we argue about what to do next. Minimally, we could fork phabricator into
the LLVM project and fix the arcanist breakage. I don’t think maintaining a fork
long term is a good idea, especially since phorge exists. We should not
advertise our fork as being “maintained” to anybody, aside from the minimal goal
of keeping existing workflows for LLVM functional while we decide on a migration
plan.

My personal opinion on the topic of “using phabricator vs github PRs” is to
stick with phabricator. I personally prefer the “push patch sets, then merge a
patch into the tree” approach to the github “fork the repo, push some changes to
your fork, then merge your fork with upstream”. I occasionally commit to CMake
(which uses gitlab), and always find the experience quite confusing and awkward.
I don’t know much about Phorge, but if it’s a Phabricator clone, and is actually
being maintained, it seems to me to be a good migration target. I would also
personally be fine with using Gerrit.

Thanks,
   Chris Tetreault
