            Bug ID: 30498
           Summary: [gdb/cli] GDB stuck in i-search after ^C
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: normal
          Priority: P2
         Component: cli
          Assignee: unassigned at sourceware dot org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

I ran into the following.

Start gdb, type ^R to start reverse-i-search, and type foo, and then ^C to quit
the i-search:
...
$ gdb -q
(failed reverse-i-search)`foo': Quit
(gdb) 
...

So far so good, let's now try to type a command, say file:
...
$ gdb -q
(failed reverse-i-search)`foo': Quit
(failed reverse-i-search)`foofile': 
...
Hmm, it seems like we're stuck in the i-search.

    [gdb/testsuite] Fix gdb.tui/pr30056.exp for native-extended-gdbserver

    When running test-case gdb.tui/pr30056.exp with target board
    native-extended-gdbserver, I run into:
    ...
    Quit^[[K^M^[[B(gdb) PASS: gdb.tui/pr30056.exp: Control-C
    Remote debugging from host ::1, port 38810^M
    ^M(failed reverse-i-search)`xyz': ^M(gdb) target extended-remote \
      localhost:2346^[[7GWARNING: Timed out waiting for EOF in server after \
      monitor exit
    ...

    This is due to the fact that ^C doesn't abort the reverse-i-search.  This
    appears to be due to a readline problem.  A PR is open about this: PR
    cli/30498.

    Add a KFAIL for the PR, and ensure that the isearch is aborted by using ^G,
    such that we have a responsive prompt to handle the "monitor exit" command
    that native-extended-gdbserver issues.

    Tested on x86_64-linux.
