The real purpose of this setting is really to override what the debugger
would otherwise guess from checking the stdin settings. So it seems
more natural to see this setting being handled inside gdb_has_a_terminal
rather than input_is_terminal (which checks for other things, such as
whether the input is stdin, for instance).
This patch also adjust the command help and the associated section in
the GDB Manual to be a little clearer about that.
gdb/ChangeLog:
* inflow.c: Include "gdbcmd.h".
(interactive_mode): New static global, moved here from top.c.
(show_interactive_mode): New function, moved here from top.c.
use gdb_has_a_terminal instead of input_from_terminal_p to
determine the current mode.
(gdb_has_a_terminal): Add handling of the "iteractive-mode"
setting.
(_initialize_inflow): Add the "set/show interactive-mode"
commands. Moved here from top.c, after having adjusted slightly
the help text.
* top.c (interactive_mode, show_interactive_mode): Delete, moved
to inflow.c.
(input_from_terminal_p): Remove handling of "interactive-mode"
setting, moved to infow.c.
(init_main): Remove creation of the "set/show interactive-mode"
commands, moved to inflow.c.
gdb/doc/ChangeLog:
* gdb.texinfo (Other Misc Settings): Rework part of the
documentation of the "set interactive mode" command.
When interactive-mode is not auto, GDB always uses that setting to
determine whether to act as if the input stream is a terminal or not.
However, this setting should only be honored if the input stream is
the standard input stream. Otherwise, we run into trouble while
source-ing a GDB script, as shown below (on x86_64-linux):
% cat script
print 1
print 2
% gdb -q
(gdb) set interactive-mode on
(gdb) source script
(gdb) print 3
$1 = 3
The lack of output and the fact that the "print 3" command returned
a value saved in $1 (as opposed to $3) indicates that the script was
not even evaluated at all.
gdb/ChangeLog:
* top.c (input_from_terminal_p): Restrict the use of interactive_mode
to the case where instream is stdin.
gdb/testsuite/ChangeLog:
* gdb.base/interact.exp: New testcase.
gdb/ChangeLog:

* python/python.c (finish_python_initialization): New function.
(_initialize_python): Move python-implemented initialization there
and call it.
(GdbMethods): Use #ifdef HAVE_PYTHON for consistency.
Redirect also uiout and stdtarg{,err} in execute_command_to_string.

(set_logging_redirect, pop_output_files, handle_redirections):

* tui/tui-io.c (tui_setup_io): Redirect also gdb_stdtargerr.
* utils.c (do_ui_out_redirect_pop, make_cleanup_ui_out_redirect_pop):
New functions.

(verify help to uiout): New tests.
* top.c (input_from_terminal_p): Return 0 on BATCH_FLAG.
* utils.c (defaulted_query): Do not explicitly check for BATCH_FLAG.
(fputs_maybe_filtered): Do not do filtering also on
! INPUT_FROM_TERMINAL_P.
