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:
* top.c (print_gdb_version): Update copyright year in version output.
gdb/gdbserverChangeLog:
* server.c (gdbserver_version): Update copyright year in version
output.
* gdbreplay.c (gdbreplay_version): Ditto.

(_initialize_python): Move python-implemented initialization there

New functions.

* gdb.python/python.exp (set height 0, collect help from uiout)
(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.
Consolidate code for displaying per-command time and space statistics to avoid
duplication. Piggyback on cleanups so that statistics get printed even when
commands terminate as a result of an error.

From Steven Johnson <sbjohnson@ozemail.com.au>:
This set of changes add "hookpost-" as an expansion on the original
hooking of commands to GDB. A Hook may now be run "AFTER" execution of
a command as well as before.
* command.h (struct cmd_list_element): Changed elements hook and hookee
to hook_pre and hookee_pre respectively. Added hook_post and hookee_post
for the post hook command operation. Added hook_in so that an executing
hook can be flagged to prevent recursion.

reflect above changes.
(delete_cmd): Remove both pre and post hooks.

characters for the readline library.

symmisc.c symtab.c thread.c top.c tracepoint.c typeprint.c valops.c:
Cast parameters passed to make_cleanup to use the new
make_cleanup_func typedef.
More warning cleanups. There are still a bunch of places where the first
argument to make_cleanup is not cast to (make_cleanup_func); these are
either due to the function fitting the make_cleanup_func specification
already (e.g. free()) or they are in files that weren't compiled when
I did my make on a Linux native system. Bwahahaha. You can see them
like this:
grep make_cleanup\ * | grep -v make_cleanup_func
I'll surely go back and clean up the remaining suspicious calls in
GDB one of these days. :-)
that
we can use this member to track real timeouts.
(hardwire_readchar): Modify for cygwin32 so that we only ever use a real
system timeout of one second. Track the "real" timeout as a series of th
ese
one second timeouts.

(wait_for): Don't reset the timeout_remaining for CYGWIN32,
since we now effectively poll the serial port.
Don't reset the current_timeout, either, since this member is used
by hardwire_readchar to track the timeout and call the ui_loop_hook.
(hardwire_readchar): Poll the serial port for Cygwin32. We timeout every
second, update the UI, and loop around doing this until we have hit the real
timeout or we get data or an error. This will allow the UI to stay active
while gdb is "blocked" talking to the target.

on the partial or full filename. Returns the full pathname.
(gdb_loadfile): Realloc additional memory
if someone loads in a file with more than 160,000
lines. I don't know if this really works because
I don't have enough memory to test it.

(gdb_loc): Return correct PC for frames
that are not the innermost frame.
(gdb_listfiles): Rewritten to use object
API. Now takes an optional dirname which will cause
only files in that directory or its subdirectories
to be returned. Now returns basenames instead of
full pathnames.
(gdb_cmd): Set/reset load_in_progress flag.
(call_wrapper): Don't pop up dialog for errors in
downloads; just abort download.
(gdbtk_load_hash): Set return value correctly.

(activate): add prompt argument for readline
(setprompt): add prompt argument for readline
* interface.tcl (gdbtk_tcl_readline): hack to get readline working

* findvar.c (registers_changed): Likewise.
Fixes memory "leak" reported by HP. Call from execute_command is for general
alloca cleanup; call from registers_changed is to fix hp's specific problem.
* Makefile.in, configure.in, aclocal.m4: Add Itcl, Tix, and
IDE configuration information.
* gdbtk.c (breakpoint_notify): Send address, linenumber and
filename when a breakpoint is set. Avoids call to bp_info.
(gdbtk_init): Call Tcl_FindExecutable(). Add code to handle
Itcl, Tix and IDE initialization.

* main.c (gdb_init): Change prototype to accept one arg.
* top.c (gdb_init): Accepts one argument which it uses to
call (*init_ui_hook), which will be gdbtk_init(). This is
used for calling Tcl_FindExecutable().

accept variable number of args for compatibility with
cchanges in gdbtk.c.

* gdbtcl/tclIndex: Regenerated.
that directory.
* defs.h utils.c (error warning): Make message be const.
* main.c (fputs_unfiltered): Only send gdb_stdout and gdb_stderr
to hook. Otherwise send it to fputs.
* monitor.c monitor.h (monitor_get_dev_name): New function. Does
the obvious.
* remote-e7000.c: Remove debugify stuff. Change printf, fprintf
to _filtered forms to make output appear in GUIs. Replace all
uses of SERIAL_READCHAR with readchar, which has better error
checking.
* (e7000_parse_device): Add prototype.
* (readchar): Improve doc. Handle random serial errors.
* (expect): Disable notice_quit code. It's busted. Remove
serial error handling (it's now handled in readchar). Remove
remote_debug echoing. That's handled in readchar as well.
* (e7000_parse_device): Remove serial_flag arg. It's not
necessary.
* (e7000_open): Split into two pieces. Second part is
e7000_start_remote, and is error protected. Now, when we connect
to the target, we setup the initial frame and registers so that
the user gets an immediate indication of where the target is.
* (gch): Remove debug output. That's handled by readchar.
* (e7000_read_inferior_memory): Handle errors better.
* (_initialize_remote_e7000): Get rid of `<xxx>' things from
command names. They show up when doing completion and confuse
things horribly.
* ser-e7kpc.c: Remove the last seven months of brain damage. Get
rid of the DLL's since we can access the device directly from Win32s
and Win95. Get rid of debugify crud.
* serial.c: Remove debugify cruft.
* (serial_logchar serial_log_command serial_write serial_readchar
serial_send_break serial_close): Merge common functionality into
serial_logchar. Clean up rest of routines.
* sparclet-rom.c: Disembowel. Leave only download routine.
Download routine now switches to remote target automatically.
* top.c (disconnect): Only define if SIGHUP is defined. Cleans
up MSVC/Win32 problem.
* utils.c (gdb_flush): Don't call hook unless it's for gdb_stdout
or gdb_stderr.
* config/sh/tm-sh.h: Define TARGET_SH for WinGDB.
* config/sparc/tm-sparclet.h: Remove override for prompt.
