981a3fb359 Constify add_prefix_cmd
This changes add_prefix_cmd to accept a const-taking function as an
argument; then fixes up all the callers.

In a couple of spots I had to add a non-const overload of a function,
because the function is passed to two different command-adding
"constructors".  These overloads are temporary; once constification is
complete they can be removed.

This patch also fixes a typo I happened to notice while constifying.

Note that this touches a couple of files (gnu-nat.c and go32-nat.c)
that I can't build.  So, while I made a best-effort there, I am not
certain they will still compile.

Tested by rebuilding.

223ffa714c Remove make_cleanup_restore_target_terminal
This removes make_cleanup_restore_target_terminal and generally
C++-ifies target terminal handling.  It changes all target_terminal_*
functions to be static members of a new target_terminal class and
changes the cleanup to be a scoped_* class.
make_cleanup_override_quit_handler is also removed in favor of simply
using scoped_restore.

Note that there are some files in this patch that I could not compile.
Considering that some of the rewrites were automated, and that none of
these files involed cleanups, I feel that this is relatively safe.

Regression tested by the buildbot.

1526853e34 Add selftests run filtering
With the growing number of selftests, I think it would be useful to be
able to run only a subset of the tests.  This patch associates a name to
each registered selftest.  It then allows doing something like:

  (gdb) maintenance selftest aarch64
  Running self-tests.
  Running selftest aarch64-analyze-prologue.
  Running selftest aarch64-process-record.
  Ran 2 unit tests, 0 failed

or with gdbserver:

  ./gdbserver --selftest=aarch64

In both cases, only the tests that contain "aarch64" in their name are
ran.  To help validate that the tests you want to run were actually ran,
it also prints a message with the test name before running each test.

Right now, all the arch-dependent tests are registered as a single test
of the selftests.  To be able to filter those too, I made them
"first-class citizen" selftests.  The selftest type is an interface,
with different implementations for "simple selftests" and "arch
selftests".  The run_tests function simply iterates on that an invokes
operator() on each test.

I changed the tests data structure from a vector to a map, because

  - it allows iterating in a stable (alphabetical) order
  - it allows to easily verify if a test with a given name has been
    registered, to avoid duplicates

There's also a new command "maintenance info selftests" that lists the
registered selftests.

72542b8ee6 gdb: Remove check for gdb_stderr == NULL
Recent changes made gdb_stderr a macro:

  #define gdb_stderr (*current_ui_gdb_stderr_ptr ())

and current_ui_gdb_stderr_ptr return this:

   &current_ui->m_gdb_stderr

The problem is that this is undefined if current_ui is NULL, which can
happen early on during gdb start up.

If we run into an error during early gdb start up then we write the
error message to gdb_stderr.  However, if we are too early during the
start up then current_ui is NULL, and using the gdb_stderr macro
triggers undefined behaviour.

We try to avoid this using a check 'gdb_stderr == NULL' which was fine
before the recent changes, but now, still triggers undefined behaviour.

A better check is instead 'current_ui == NULL' which is what I use in
this patch.

Triggering this failure is pretty hard, most of the really early errors
are only triggered if pretty basic things are not as expected, for
example, if the default signal handlers are not as expected.  Seeing one
of these errors trigger usually means that someone working on gdb has
made an incorrect change.  Still, the errors are present in gdb, and
should we ever trigger one it would be nice if gdb didn't crash.

For testing this change I've been applying this patch which adds an
unconditional error into a function called early during gdb start up.
Later in the same function is a real error call which, in some
circumstances could be triggered:

  ## START ##

This changes gdb_realpath to return a unique_xmalloc_ptr and fixes up
the callers.  This allows removing some cleanups.  This change by

8268c77870 Eliminate make_cleanup_obstack_free, introduce auto_obstack
This commit eliminates make_cleanup_obstack_free, replacing it with a
new auto_obstack type that inherits obstack to add cdtors.

These changes in the parsers may not be obvious:

 -  obstack_init (&name_obstack);
 -  make_cleanup_obstack_free (&name_obstack);
 +  name_obstack.clear ();

Here, the 'name_obstack' variable is a global.  The change means that
the obstack's contents from a previous parse will stay around until
the next parsing starts.  I.e., memory won't be reclaimed until then.
I don't think that's a problem, these objects don't really grow much
at all.

The other option I tried was to add a separate type that is like
auto_obstack but manages an external obstack, just for those cases.  I
like the current approach better as that other approach adds more
boilerplate and yet another type to learn.

156525114c Move parts of inferior job control to common/
This commit moves a few bits responsible for dealing with inferior job
control from GDB to common/, which makes them available to gdbserver.
This is necessary for the upcoming patches that will share
fork_inferior et al between GDB and gdbserver.

We move some parts of gdb/terminal.h to gdb/common/common-terminal.h,
especifically the code that checks terminal features and that are used
to set job_control accordingly.

After sharing parts of gdb/terminal.h, we also to share the two
functions on gdb/inflow.c that are going to be needed by the
fork_inferior rework.  They are 'gdb_setpgid' and the new
'have_job_control'.  I've also taken the opportunity to give a more
meaningful name to "inflow.c" on common/.  Now it is called
"job-control.c" (thanks Pedro for the suggestion).

gdb/ChangeLog:
2017-06-07  Sergio Durigan Junior  <sergiodj@redhat.com>

	* Makefile.in (SFILES): Add "common/job-control.c".
	(HFILES_NO_SRCDIR): Add "common/job-control.h".

26a06916b6 Do not send queries on secondary UIs
This is a follow-up to

  https://sourceware.org/ml/gdb-patches/2017-02/msg00261.html

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).

gdb/ChangeLog:

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

gdb/testsuite/ChangeLog:

	* gdb.base/new-ui.exp (do_test): Test queries behavior on main
	and extra UIs.

d7e747318f Eliminate make_cleanup_ui_file_delete / make ui_file a class hierarchy
This patch starts from the desire to eliminate
make_cleanup_ui_file_delete, but then goes beyond.  It makes ui_file &
friends a real C++ class hierarchy, and switches temporary
ui_file-like objects to stack-based allocation.

- mem_fileopen -> string_file

mem_fileopen is replaced with a new string_file class that is treated
as a value class created on the stack.  This alone eliminates most
make_cleanup_ui_file_delete calls, and, simplifies code a whole lot
(diffstat shows around 1k loc dropped.)

string_file's internal buffer is a std::string, thus the "string" in
the name.  This simplifies the implementation much, compared to
mem_fileopen, which managed growing its internal buffer manually.

- ui_file_as_string, ui_file_strdup, ui_file_obsavestring all gone

The new string_file class has a string() method that provides direct
writable access to the internal std::string buffer.  This replaced
ui_file_as_string, which forced a copy of the same data the stream had
inside.  With direct access via a writable reference, we can instead
move the string out of the string_stream, avoiding deep string
copying.

Related, ui_file_xstrdup calls are replaced with xstrdup'ping the
stream's string, and ui_file_obsavestring is replaced by
obstack_copy0.

With all those out of the way, getting rid of the weird ui_file_put
mechanism was possible.

- New ui_file::printf, ui_file::puts, etc. methods

These simplify / clarify client code.  I considered splitting
client-code changes, like these, e.g.:

  -  stb = mem_fileopen ();
  -  fprintf_unfiltered (stb, "%s%s%s",
  -		      _("The valid values are:\n"),
  -		      regdesc,
  -		      _("The default is \"std\"."));
  +  string_file stb;
  +  stb.printf ("%s%s%s",
  +	      _("The valid values are:\n"),
  +	      regdesc,
  +	      _("The default is \"std\"."));

In two steps, with the first step leaving fprintf_unfiltered (etc.)
calls in place, and only afterwards do a pass to change all those to
call stb.printf etc..  I didn't do that split, because (when I tried),
it turned out to be pointless make-work: the first pass would have to
touch the fprintf_unfiltered line anyway, to replace "stb" with
"&stb".

- gdb_fopen replaced with stack-based objects

This avoids the need for cleanups or unique_ptr's.  I.e., this:

      struct ui_file *file = gdb_fopen (filename, "w");
      if (filename == NULL)
 	perror_with_name (filename);
      cleanups = make_cleanup_ui_file_delete (file);
      // use file.
      do_cleanups (cleanups);

is replaced with this:

      stdio_file file;
      if (!file.open (filename, "w"))
 	perror_with_name (filename);
      // use file.

- odd contorsions in null_file_write / null_file_fputs around when to
  call to_fputs / to_write eliminated.

- Global null_stream object

A few places that were allocating a ui_file in order to print to
"nowhere" are adjusted to instead refer to a new 'null_stream' global
stream.

- TUI's tui_sfileopen eliminated.  TUI's ui_file much simplified

The TUI's ui_file was serving a dual purpose.  It supported being used
as string buffer, and supported being backed by a stdio FILE.  The
string buffer part is gone, replaced by using of string_file.  The
'FILE *' support is now much simplified, by making the TUI's ui_file
inherit from stdio_file.

192b62ce0b Use class to manage BFD reference counts
This introduces a new specialization of gdb::ref_ptr that can be used
to manage BFD reference counts.  Then it changes most places in gdb to
use this new class, rather than explicit reference-counting or
cleanups.  This patch removes make_cleanup_bfd_unref.

If you look you will see a couple of spots using "release" where a use
of gdb_bfd_ref_ptr would be cleaner.  These will be fixed in the next
patch.

I think this patch fixes some latent bugs.  For example, it seems to
me that previously objfpy_add_separate_debug_file leaked a BFD.

I'm not 100% certain that the macho_symfile_read_all_oso change is
correct.  The existing code here is hard for me to follow.  One goal
of this sort of automated reference counting, though, is to make it
more difficult to make logic errors; so hopefully the code is clear
now.

fc4007c969 Remove make_cleanup_htab_delete
This removes make_cleanup_htab_delete in favor of destructors,
building on an earlier patch that added the htab_up typedef.

Testing revealed that more cleanup-removal work was needed in
dwarf2loc.c, so this version of the patch changes code there to use
unordered_set and vector, removing some more cleanups.

112e8700a6 Class-ify ui_out
This patch finalizes the C++ conversion of the ui-out subsystem, by
turning the ui_out and ui_out_impl structures into a single class
hierarchy.  ui_out functions are turned into virtual methods of that new
class, so as a result there are a lot of call sites to update.

In the previous version of the patchset, there were separate ui_out and
ui_out_impl classes, but it wasn't really useful and added boilerplate.
In this version there is simply an ui_out base class that is
extended for CLI, TUI and MI.

It's a bit hard to maintain a ChangeLog for such a big patch, I did my
best but I'm sure there are some missing or outdated info in there...

dcb07cfa15 gdb: Use C++11 std::chrono
This patch fixes a few problems with GDB's time handling.

#1 - It avoids problems with gnulib's C++ namespace support

On MinGW, the struct timeval that should be passed to gnulib's
gettimeofday replacement is incompatible with libiberty's
timeval_sub/timeval_add.  That's because gnulib also replaces "struct
timeval" with its own definition, while libiberty expects the
system's.

E.g., in code like this:

  gettimeofday (&prompt_ended, NULL);
  timeval_sub (&prompt_delta, &prompt_ended, &prompt_started);
  timeval_add (&prompt_for_continue_wait_time,
               &prompt_for_continue_wait_time, &prompt_delta);

That's currently handled in gdb by not using gnulib's gettimeofday at
all (see common/gdb_sys_time.h), but that #undef hack won't work with
if/when we enable gnulib's C++ namespace support, because that mode
adds compile time warnings for uses of ::gettimeofday, which are hard
errors with -Werror.

#2 - But there's an elephant in the room: gettimeofday is not monotonic...

We're using it to:

  a) check how long functions take, for performance analysis
  b) compute when in the future to fire events in the event-loop
  c) print debug timestamps

But that's exactly what gettimeofday is NOT meant for.  Straight from
the man page:

~~~
       The time returned by gettimeofday() is affected by
       discontinuous jumps in the system time (e.g., if the system
       administrator manually changes the system time).  If you need a
       monotonically increasing clock, see clock_gettime(2).
~~~

std::chrono (part of the C++11 standard library) has a monotonic clock
exactly for such purposes (std::chrono::steady_clock).  This commit
switches to use that instead of gettimeofday, fixing all the issues
mentioned above.

9c37b5aed9 Remove Java support
This patch removes the Java support from gdb.  gcj has not seen much
development or use for years now, and was recently removed from GCC.
This patch changes gdb to follow; in the unlikely event that there are
still users using gcj, they can continue to use an older gdb to debug.

a97e29d248 Use std::string rather than dyn-string
This patch changes some code in cli-cmds.c to use std::string rather
than dyn-string, removing some cleanups.  Since this was the last use
of dyn-string in gdb, this patch also removes
make_cleanup_dyn_string_delete.

3e25a500a1 Remove some unnecessary code
This patch removes some unnecessary code.  In particular,
terminate_minimal_symbol_table is declared in minsyms.h, so it doesn't
need to be declared in objfiles.h as well.  And,
restore_ui_out_closure was rendered unnecessary by an earlier patch,
so the structure definition can be removed now.

I'm checking this in as obvious.

Tested by rebuilding on x86-64 Fedora 24 with --enable-targets=all;
which would notice any missing includes of minsyms.h.

3eb7562a98 Fix PR gdb/20418 - Problems with synchronous commands and new-ui
When executing commands on a secondary UI running the MI interpreter,
some commands that should be synchronous are not.  MI incorrectly
continues processing input right after the synchronous command is
sent, before the target stops.

The problem happens when we emit MI async events (=library-loaded,
etc.), and we go about restoring the previous terminal state, we end
up calling target_terminal_ours, which incorrectly always installs the
current UI's input_fd in the event loop...  That is, code like this:

   old_chain = make_cleanup_restore_target_terminal ();
   target_terminal_ours_for_output ();

   fprintf_unfiltered (mi->event_channel, "library-loaded");

...

   do_cleanups (old_chain);

The fix is to move the add_file_handler/delete_file_handler calls out
of target_terminal_$foo, making these completely no-ops unless called
with the main UI as current UI.

268a799a45 Make stdin be per UI
This commit makes each UI have its own "stdin" stream pointer.  This
is used to determine whether the "from_tty" argument to
execute_command, etc. should be true.

Related, this commit makes input_from_terminal_p take an UI parameter,
and then avoids the gdb_has_a_terminal in it.  gdb_has_a_terminal only
returns info on gdb's own main/primary terminal (the real stdin).
However, the places that call input_from_terminal_p really want to
know is whether the command came from an interactive tty.  This patch
thus renames input_from_terminal_p to input_interactive_p for clarity,
and then makes input_interactive_p check for "set interactive" itself,
along with ISATTY, instead of calling gdb_has_a_terminal.  Actually,
quit_force wants to call input_interactive_p _after_ stdin is closed,
we can't call ISATTY that late.  So instead we save the result of
ISATTY in a field of the UI.

	* cli/cli-script.c (read_next_line): Adjust to per-UI stdin.
