[flang-dev] Bugzilla migration is stopped again

[Anton Korobeynikov via flang-dev]

Dear All,

I hate to say this, but the migration was stopped again. Now it seems
that GitHub does not rewrite issue references properly during the
transfer (sick!). Let me show what the problem is exactly:

Consider two issues: A and B, where A will reference B and B will
reference A. In our case this is used to model various relations like
"duplicates / is duplicated by", "blocks / is blocked by", "depends on
/ required by". So, in bz archive A will reference B as #B and B
will reference #A.

Now, let's migrate A. The references will be rewritten. #B =>
bz-archive#B and #A => llvm-project#A. However, after migration of B
only one reference is rewritten llvm-project#A => #A, the bz-archive#B
link in the issue A will not be rewritten and therefore a dangling
reference will appear.

For us this means that we will lose all links to duplicate issues, and
(more important!) to linked issues in the meta bugs.

I informed GitHub about the bug and I am waiting for their answer.
