repl completion shows qualification warning inline

[IanButterworth]

julia> using Downloads

julia> download(WARNING: both Downloads and Base export "download"; uses of it in module Main must be qualified

i.e. typing download( will cause the warning to print.

Will be fixed by the full binding partition PR, since this will no longer by a binding resolution point.

[IanButterworth]

Will that be backported to 1.11?

[Keno]

No

[IanButterworth]

Ok. We need a solution for 1.11 then. Disable the check if in tab completion mode? Would that be possible?

[Keno]

It's not easy, because the warning is being emitted from deep in the binding resolution code as soon as someone asks the question about the binding.

[IanButterworth]

I looked into fixing this by disallowing anything to print to stdout/stderr during calls to complete_line, but redirect_stderr doesn't appear to redirect c prints that are to JL_STDERR. Is that expected?

Seems to be specific to devnull #55958

[IanButterworth]

#55959 was reverted. This is fixed by removing the c warning, and on 1.11 by additionally backporting the improved hints.
