Hi Sam,

Sorry for such a huge delay. I don't know if this is still relevant as I've
seen multiple related discussion over the mailing lists but I didn't manage
to follow them and I thought I should probably finish my thoughts from way

Are you referring to the "Moving LLVM Projects to GitHub" proposal? Oh, I
thought it's stale now. Anyway, from what I understand, the issue tracking
is not considered in that proposal, i.e. IIUC GitHub Issues are not the
proposed alternative to LLVM Bugzilla. I am not very familiar with the
proposal and the process, but I personally would think that it would be
better to use GitHub issues instead of Bugzilla if the code would already
be there.

Yes, I think it's a long time. However, if the move happens we would also
have to export the existing issues (to the new repository?) somehow, which
does not seem like *a lot* of work, but it's still some effort.

I see. From my perspective, the common part is that there are many
obstacles for the bugs to be

* discovered
* confirmed
* fixed

While the discussion I mentioned mostly focuses on the first two parts, the
latter doesn't come without these bugs being verified by the
developers/users which makes me believe there are common problems.

Fair enough, but I also think that this might be a cause of user confusion:
LLVM guidelines say "please report bugs on Bugzilla"; Clangd is a part of
LLVM source tree, but it would have a separate process. Honestly, I
personally think it would be most convinient to have Clangd as a separate
repository under github.com/llvm/clangd but I know there are multiple
opinions on that and that there are some experiments with GitHub's LLVM org
going on right now.

Again, sorry for the late reply,
