[llvm-dev] Phabricator Creator Pulling the Plug

Fri Oct 1 01:24:00 PDT 2021

I would like to add a third blocker to Mehdi's list:

3) We first would need to finish our ongoing Bugzilla to GitHub Issues
migration: At the moment the plan is to use the old bug ID in bugzilla as
issue ID on GitHub. However issues and Pull Requests share the same
namespace. So once we start using Pull Requests this would eat up the
numbers for the bugs/issues.

This is certainly not a show stopper, but something to decide on. I see two
options here:

1) We delay using Pull Requests until the Bugzilla to Issues migration is
completed.
2) We give up the requirement to keep the bug IDs and assign the new IDs as
they are available.

Best,
Christian
