GDB 12 preparation -- 2022-02-20 update

[Joel Brobecker]

Hi everyone,

A quick update regarding the list of issues currently identified
as being a priority for GDB 12. Overall, we can see that there is
progress :-).


---

Fixed Since the Previous Update:
--------------------------------

  <none>


Added Since the Last Update:
----------------------------

  <none>


Other Ongoing Items:
--------------------

  * [BarisA/AndrewB] <PR cli/28833>
    Ctrl-D distorts GDB prompt
    https://sourceware.org/bugzilla/show_bug.cgi?id=28833


        Baris requested that we consider the bug above, which seems
        to be a GDB 11 regression for Baris.

        Andrew posted progress on the PR. Currently coordinating
        with the readline maintainers (seems to be progressing well)...

  * [AndrewB] create GDB/MI commands using python

        Explicit request to include in GDB 12; accepted as the patches
        were sent prior to the start of the GDB 12 release process.

        Latest version (v3) posted by Andrew is waiting for review:
        https://sourceware.org/pipermail/gdb-patches/2022-February/185821.html

  * [JohnB] gdbsupport: Add an event-pipe
    https://sourceware.org/pipermail/gdb-patches/2022-January/185345.html

        v4 has been reviewed by TomT (Jan 14th). I reviewed the following
        patches:
          - #4/15 (new, and enables async mode inside of target_resume)
          - #5/15 (just slightly adjusted after #4)
          - #7/15 (inf_ptrace::wait now returns IGNORE instead of
            throwing  when waitpid fails)

        As far as I know, the whole series has been approved, now.


Reminder: Tentative Schedule:
-----------------------------

  - GDB 12 branching 2 months from now (~Mar 20-25);
  - GDB 12.1 release 2 weeks later, so early Apr.

My ideal solution here would be to have an official readline patch
committed upstream, which we can then backport, along with a GDB patch,
to fix this issue.

If it looks like a readline patch isn't going to appear any time soon,
then I'll post something later this week which we can consider - maybe
just including it in the GDB 12 branch, and then wait for an official
readline patch to include in master.

But I think we can give upstream readline a few more days to see how
that plays out.

Thanks,
Andrew

Agreed. I don't think we're in a rush, since we are still a month
away from our target branching date.

Thanks for the review, I've pushed the series now.
