The timeouts were caused by an attempt to match a bell character (x07) that
doesn't show up on my particular test setup.
The bell character is output whenever one tries to complete a pattern and there
are multiple possible matches. When there is only one possible match, GDB will
complete the input pattern without outputting the bell character.
The reason for the discrepancy in this test's behavior is due to the use of
"main" for a unique name test.
On glibc-based systems, GDB may notice the "main_arena" symbol, which is
a data global part of glibc's malloc implementation. Therefore a bell character
will be output because we have a couple possible completion matches.
GDB should not be outputting such a data symbol as a possible match, but this
problem may/will be addressed in a future change and is besides the point of
this particular change.
On systems that are not based on glibc, GDB will not see any other possible
matches for completing "main", so there will be no bell characters.
The use of main is a bit fragile though, so the patch adds a new local function
with a name that has a greater chance of being unique and adjusts the test to
iuse it.
I've also added the regular expression switch (-re) to all the
gdb_test_multiple calls that were missing it. Hopefully this will reduce the
chances of someone wasting time trying to match a regular expression (a much
more common use case) when, in reality, the pattern is supposed to be matched
literally.

This test attempts to load a x86 core file no matter what target
architectures the tested GDB supports. If GDB doesn't know how to handle
a i386 target, it is very likely the core file will not be recognized.
In this case we should still attempt to load a core file to make sure GDB
doesn't crash or throws an internal error. But we should not proceed to
try to read memory unconditionally.
This patch makes the test check for proper i386 arch support in GDB and bails
out if i386 is not supported and the core file format is not recognized.
This addresses the spurious aarch64-elf failures i'm seeing for this test.

This patch restricts queries to the main UI, which allows to avoid two
different problems.
The first one is that GDB is issuing queries on secondary MI channels
for which a TTY is allocated. The second one is that GDB is not able to
handle queries on two (CLI) UIs simultaneously. Restricting queries to
the main UI allows to bypass these two problems.
More details on how/why these two problems happen:
1. Queries on secondary MI UI
The current criterion to decide if we should query the user is whether
the input stream is a TTY. The original way to start GDB in MI mode
from a front-end was to create a subprocess with pipes to its
stdin/stdout. In this case, the input was considered non-interactive
and queries were auto-answered. Now that front-ends can create the MI
channel as a separate UI connected to a dedicated TTY, GDB now
considers this input stream as interactive and sends queries to it.
By restricting queries to the main UI, we make sure we never query on
the secondary MI UI.
2. Simultaneous queries
As Pedro stated it, when you have two queries on two different CLI UIs
at the same time, you end up with the following pseudo stack:
#0 gdb_readline_wrapper
#1 defaulted_query // for UI #2#2 handle_command
#3 execute_command ("handle SIGTRAP" ....
#4 stdin_event_handler // input on UI #2#5 gdb_do_one_event
#7 gdb_readline_wrapper
#8 defaulted_query // for UI #1#9 handle_command
#10 execute_command ("handle SIGINT" ....
#11 stdin_event_handler // input on UI #1#12 gdb_do_one_event
#13 gdb_readline_wrapper
trying to answer the query on UI #1 will therefore answer for UI #2.
By restricting the queries to the main UI, we ensure that there will
never be more than one pending query, since you can't have two queries
on a UI at the same time.
I added a snippet to gdb.base/new-ui.exp to verify that we get a query
on the main UI, but that we don't on the secondary one (or, more
precisely, that it gets auto-answered).

* utils.c (defaulted_query): Don't query on secondary UIs.

This patch introduces a bit of infrastructure -- namely, a minimal
std::optional analogue called gdb::optional, and an RAII template
class that works like make_cleanup_ui_out_tuple_begin_end or
make_cleanup_ui_out_list_begin_end -- and then uses these in the
Python code. This removes a number of cleanups and generally
simplifies this code.
std::optional is only available in C++17. Normally I would have had
this code check __cplusplus, but my gcc apparently isn't new enough to
find <optional>, even with -std=c++1z; so, because I could not test
it, the patch does not do this.

This commit removes interp::quiet_p / interp_quiet_p /
interp_set_quiet, because AFAICS, it doesn't really do anything.
interp_quiet is only ever checked inside interp_set nowadays:
if (!first_time && !interp_quiet_p (interp))
{
xsnprintf (buffer, sizeof (buffer),
"Switching to interpreter \"%.24s\".\n", interp->name);
current_uiout->text (buffer);
}
I did a bit of archaelogy, and found that back in 4a8f6654 (2003), it
was also called in another place, to decide whether to print the CLI
prompt.
AFAICS, that condition is always false today, making that if/then
block always dead code. If we remove that code, then there are no
interp_quiet_p uses left in the tree, so we can remove it all.
There are two paths that lead to interp_set calls:
#1 - When installing the top level interpreter. In this case,
FIRST_TIME is true.
#2 - In interpreter_exec_cmd. In this case, the interpreter is always
set quiet before interp_set is called.
Grepping a gdb.log of an x86_64 GNU/Linux run for "Switching to
interpreter" (before this patch) doesn't find any hits.
I suspect the intention of this message was to support something like
a "set interpreter ..." command that would change the interpreter
permanently. But there's no such command.

While looking into PR rust/21097, I found that ptype of a

In particular, it would leave out the members of a tuple struct.
Further testing showed that it also did the wrong thing for ordinary
struct members as well.
This patch fixes these problems. I'm marking it as being associated
with the PR, since that is where the discovery was made; but this
doesn't actually fix that PR (which I think ultimately is due to a
