Great.
I think that doesn't really cover the bug yet fully though, because
with an unfixed gdb, "show history unlimited" shows "unlimited",
but the readline history still ends up disabled. So I think we
should try a "show commands" after the "show history size". For the
unlimited case, we could test that the history contains a few
commands and that the last couple were what we just issued.
And for size==0, make sure that history really is empty.
Something like:
gdb_test "show history size" "The size of the command history is $size."
if {$home == "unlimited"} {
gdb_test "show comands" " show history size\r\n[ \t]+show commands"
} else {
gdb_test_no_output "show commands"
}
(FYI: to run a command without having it enter the command history,
prefix it with "server". That may be useful for testing.)
Thanks,
Pedro Alves
