Tom Tromey 268a13a5a3 Rename common to gdbsupport
This is the next patch in the ongoing series to move gdbsever to the
top level.

This patch just renames the "common" directory.  The idea is to do
this move in two parts: first rename the directory (this patch), then
move the directory to the top.  This approach makes the patches a bit
more tractable.

I chose the name "gdbsupport" for the directory.  However, as this
patch was largely written by sed, we could pick a new name without too
much difficulty.

Tested by the buildbot.

Alan Hayward 766f883622 Suppress SIGTTOU when handling errors
Calls to error () can cause SIGTTOU to send gdb to the background.

For example, on an Arm build:
  (gdb) b main
  Breakpoint 1 at 0x10774: file /build/gdb/testsuite/../../../src/binutils-gdb/gdb/testsuite/gdb.base/watchpoint.c, line 174.
  (gdb) r
  Starting program: /build/gdb/testsuite/outputs/gdb.base/watchpoint/watchpoint

  [1]+  Stopped                 ../gdb ./outputs/gdb.base/watchpoint/watchpoint
  localhost$ fg
  ../gdb ./outputs/gdb.base/watchpoint/watchpoint
  Cannot parse expression `.L1199 4@r4'.
  warning: Probes-based dynamic linker interface failed.
  Reverting to original interface.

The SIGTTOU is raised whilst inside a syscall during the call to tcdrain.
Fix is to use scoped_ignore_sigttou to ensure SIGTTOU is blocked.

In addition fix include comments - job_control is not included via terminal.h

gdb/ChangeLog:

	* event-top.c: Remove include comment.
	* inflow.c (class scoped_ignore_sigttou): Move from here...
	* inflow.h (class scoped_ignore_sigttou): ...to here.
	* ser-unix.c (hardwire_drain_output): Block SIGTTOU during drain.
	* top.c:  Remove include comment.

Joel Brobecker 42a4f53d2b Update copyright year range in all GDB files.
This commit applies all changes made after running the gdb/copyright.py
script.

Note that one file was flagged by the script, due to an invalid
copyright header
(gdb/unittests/basic_string_view/element_access/char/empty.cc).
As the file was copied from GCC's libstdc++-v3 testsuite, this commit
leaves this file untouched for the time being; a patch to fix the header
was sent to gcc-patches first.

Pedro Alves e671cd59d7 Per-inferior target_terminal state, fix PR gdb/13211, more
In my multi-target branch I ran into problems with GDB's terminal
handling that exist in master as well, with multi-inferior debugging.

This patch adds a testcase for said problems
(gdb.multi/multi-term-settings.exp), fixes the problems, fixes PR
gdb/13211 as well (and adds a testcase for that too,
gdb.base/interrupt-daemon.exp).

The basis of the problem I ran into is the following.  Consider a
scenario where you have:

 - inferior 1 - started with "attach", process is running on some
   other terminal.

 - inferior 2 - started with "run", process is sharing gdb's terminal.

In this scenario, when you stop/resume both inferiors, you want GDB to
save/restore the terminal settings of inferior 2, the one that is
sharing GDB's terminal.  I.e., you want inferior 2 to "own" the
terminal (in target_terminal::is_ours/target_terminal::is_inferior
sense).

Unfortunately, that's not what you get currently.  Because GDB doesn't
know whether an attached inferior is actually sharing GDB's terminal,
it tries to save/restore its settings anyway, ignoring errors.  In
this case, this is pointless, because inferior 1 is running on a
different terminal, but GDB doesn't know better.

And then, because it is only possible to have the terminal settings of
a single inferior be in effect at a time, or make one inferior/pgrp be
the terminal's foreground pgrp (aka, only one inferior can "own" the
terminal, ignoring fork children here), if GDB happens to try to
restore the terminal settings of inferior 1 first, then GDB never
restores the terminal settings of inferior 2.

This patch fixes that and a few things more along the way:

 - Moves enum target_terminal::terminal_state out of the
   target_terminal class (it's currently private) and makes it a
   scoped enum so that it can be easily used elsewhere.

 - Replaces the inflow.c:terminal_is_ours boolean with a
   target_terminal_state variable.  This allows distinguishing is_ours
   and is_ours_for_output states.  This allows finally making
   child_terminal_ours_1 do something with its "output_only"
   parameter.

 - Makes each inferior have its own copy of the
   is_ours/is_ours_for_output/is_inferior state.

 - Adds a way for GDB to tell whether the inferior is sharing GDB's
   terminal.  Works best on Linux and Solaris; the fallback works just
   as well as currently.

 - With that, we can remove the inf->attach_flag tests from
   child_terminal_inferior/child_terminal_ours.

 - Currently target_ops.to_ours is responsible for both saving the
   current inferior's terminal state, and restoring gdb's state.
   Because each inferior has its own terminal state (possibly handled
   by different targets in a multi-target world, even), we need to
   split the inferior-saving part from the gdb-restoring part.  The
   patch adds a new target_ops.to_save_inferior target method for
   that.

 - Adds a new target_terminal::save_inferior() function, so that
   sequences like:

     scoped_restore_terminal_state save_state;
     target_terminal::ours_for_output ();

   ... restore back inferiors that were
   target_terminal_state::is_inferior before back to is_inferior, and
   leaves inferiors that were is_ours alone.

 - Along the way, this adds a default implementation of
   target_pass_ctrlc to inflow.c (for inf-child.c), that handles
   passing the Ctrl-C to a process running on GDB's terminal or to
   some other process otherwise.

 - Similarly, adds a new target default implementation of
   target_interrupt, for the "interrupt" command.  The current
   implementation of this hook in inf-ptrace.c kills the whole process
   group, but that's incorrect/undesirable because we may not be
   attached to all processes in the process group.  And also, it's
   incorrect because inferior_process_group() doesn't really return
   the inferior's real process group id if the inferior is not a
   process group leader...  This is the cause of PR gdb/13211 [1],
   which this patch fixes.  While at it, that target method's "ptid"
   parameter is eliminated, because it's not really used.

 - A new test is included that exercises and fixes PR gdb/13211, and
   also fixes a GDB issue reported on stackoverflow that I ran into
   while working on this [2].  The problem is similar to PR gdb/13211,
   except that it also triggers with Ctrl-C.  When debugging a daemon
   (i.e., a process that disconnects from the controlling terminal and
   is not a process group leader, then Ctrl-C doesn't work, you just
   can't interrupt the inferior at all, resulting in a hung debug
   session.  The problem is that since the inferior is no longer
   associated with gdb's session / controlling terminal, then trying
   to put the inferior in the foreground fails.  And so Ctrl-C never
   reaches the inferior directly.  pass_signal is only used when the
   inferior is attached, but that is not the case here.  This is fixed
   by the new child_pass_ctrlc.  Without the fix, the new
   interrupt-daemon.exp testcase fails with timeout waiting for a
   SIGINT that never arrives.

[1] PR gdb/13211 - Async / Process group and interrupt not working
https://sourceware.org/bugzilla/show_bug.cgi?id=13211

[2] GDB not reacting Ctrl-C when after fork() and setsid()
https://stackoverflow.com/questions/46101292/gdb-not-reacting-ctrl-c-when-after-fork-and-setsid

Note this patch does _not_ fix:

 - PR gdb/14559 - The 'interrupt' command does not work if sigwait is in use
   https://sourceware.org/bugzilla/show_bug.cgi?id=14559

 - PR gdb/9425 - When using "sigwait" GDB doesn't trap SIGINT. Ctrl+C terminates program when should break gdb.
   https://sourceware.org/bugzilla/show_bug.cgi?id=9425

The only way to fix that that I know of (without changing the kernel)
is to make GDB put inferiors in a separate session (create a
pseudo-tty master/slave pair, make the inferior run with the slave as
its terminal, and have gdb pump output/input on the master end).

Pedro Alves 726e13564b Assume termios is available, remove support for termio and sgtty
This commit garbage collects the termio and sgtty support.

GDB's terminal handling code still has support for the old termio and
sgtty interfaces in addition to termios.  However, I think it's pretty
safe to assume that for a long, long time, Unix-like systems provide
termios.  GNU/Linux, Solaris, Cygwin, AIX, DJGPP, macOS and the BSDs
all have had termios.h for many years.  Looking around the web, I
found discussions about FreeBSD folks trying to get rid of old sgtty.h
a decade ago:

  https://lists.freebsd.org/pipermail/freebsd-hackers/2007-March/019983.html

So I think support for termio and sgtty in GDB is just dead code that
is never compiled anywhere and is just getting in the way.  For
example, serial_noflush_set_tty_state and the raw<->cooked concerns
mentioned in inflow.c only exist because of sgtty (see
hardwire_noflush_set_tty_state).

Regtested on GNU/Linux.

Confirmed that I can still build Solaris, DJGPP and AIX GDB and that
the resulting GDBs still include the termios.h-guarded code.
Confirmed mingw-w64 GDB still builds and skips the termios.h-guarded
code.

Sergio Durigan Junior be628ab814 Create gdb_termios.h (and cleanup gdb/{,gdbserver/}terminal.h)
As requested, I'm sending this as a separate patch because it is ready
to be included as-is.

The idea here is that both gdb/terminal.h and gdb/gdbserver/terminal.h
share the same code, which is responsible for setting a bunch of
defines on based on the presence of termios.h and a few other headers.
This simple patch just moves this common code to common/gdb_termios.h
and makes the necessary adjustments on both GDB and gdbserver so that
they can use this new header.  It also implements the some header
checks on common/common.m4.

As a bonus, gdb/gdbserver/terminal.h can be removed because it's now
empty.

Built on x86_64, no regressions found.
