make -gdb-exit call disconnect_tracing too, and don't lose history if the target errors on "quit" Gareth mentions in PR gdb/15275: "The MI '-gdb-exit' command mi_cmd_gdb_exit() never calls disconnect_tracing() and therefore exits correctly." It should, so to get out of tfind mode, as quit may detach instead of kill, and we don't want to confuse the memory/register accesses etc. of the detach process. So we should push down the disconnect tracing bits at least to quit_force. But we can't as is, as that would swallow the error thrown by answering "no" to: Trace is running but will stop on detach; detach anyway? (y or n) So to address that, we split disconnect_tracing in two. One part that does the query, and another part that does the rest, and we make quit_force call the latter. Looking at quit_force, it does several things, some of which are a bit independent of the others. It first kills/detaches, and then writes history, and then runs the final cleanups. It seems better to me to do each of these things even if the previous thing throws. E.g., as is, if something throws while detaching, then we skip writing history. Tested on x86_64 Fedora 17. gdb/ 2013-04-10 Pedro Alves <palves@redhat.com> * cli/cli-cmds.c (quit_command): Call query_if_trace_running instead of disconnect_tracing. * infcmd.c (detach_command, disconnect_command): Call query_if_trace_running.

Remove the target from the event loop while in secondary prompts If a pagination prompt triggers while the target is running, and the target exits before the user responded to the pagination query, this happens: Starting program: foo ---Type <return> to continue, or q <return> to quit---No unwaited-for children left. Couldn't get registers: No such process. Couldn't get registers: No such process. Couldn't get registers: No such process. (gdb) Couldn't get registers: No such process. (gdb) To reiterate, the user hasn't replied to the pagination prompt above. A pagination query nests an event loop (in gdb_readline_wrapper). In async mode, in addition to stdin and signal handlers, we'll have the target also installed in the event loop still. So if the target reports an event, that wakes up the nested event loop, which calls into fetch_inferior_event etc. to handle the event which generates further output, all while we should be waiting for pagination confirmation... (TBC, any target event that generates output ends up spuriously waking up the pagination, though exits seem to be the worse kind.) I've played with a couple different approaches to fixing this, while at the same time trying to avoid being invasive. Both revolve around not listening to target events while in a pagination prompt (doing anything else I think would be a much bigger change). The approach taken just removes the target from the event loop while within gdb_readline_wrapper. The other approach used gdb_select directly, with only input_fd installed, but that had the issue that it didn't handle the async signal handlers, and turned out to be a bit more code than the first version. gdb/ 2014-07-14 Pedro Alves <palves@redhat.com> PR gdb/17072 * top.c: Include "inf-loop.h".

Add new command to create extra console/mi UIs With all the previous plumbing in place, it's now easy to add a command that actually creates a new console/mi UI. The intended use case is to make it possible and easy for MI frontends to provide a fully featured GDB console to users, with readline support, command line editing, history, etc., just like if gdb was started on the command line. Currently MI frontends have to try to implement all of that theirselves and make use of "-interpreter-exec console ...", which is far from perfect. If you ever tried Eclipse's gdb console window, you'll know what I mean... Instead of trying to multiplex console through MI, this command let's just leverage all the built in readline/editing support already inside gdb. The plan is for the MI frontend to start GDB in regular console mode, running inside a terminal emulator widget embedded in Eclipse (which already exists, for supporting the shell widget; other frontends have similar widgets), and then tell GDB to run a full MI interpreter on an specified input/output device, independent of the console. My original prototype planned to do things the other way around -- start GDB in MI mode, and then start an extra CLI console on separate tty. I handed over that prototype to Marc Khouzam @ Eclipse CDT, and after experimentation and discussion, we ended up concluding that starting GDB in CLI mode instead was both easier and actually also supported an interesting use case -- connect an Eclipse frontend to a GDB that is already running outside Eclipse. The current usage is "new-ui <interpreter> <tty>". E.g., on a terminal run this scriplet: $ cat gdb-client #!/bin/bash reset tty tail -f /dev/null $ gdb-client /dev/pts/15 Now run gdb on another terminal, and tell it to start a MI interpreter on the tty of the other terminal: ... (gdb) new-ui mi /dev/pts/15 New UI allocated Now back to the the gdb-client terminal, we'll get an MI prompt, ready for MI input: /dev/pts/15 =thread-group-added,id="i1" (gdb) You can also start a new UI running a CLI, with: (gdb) new-ui console /dev/pts/15 Though note that this console won't support readline command editing. It works as if "set editing off" was entered. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * interps.c (set_top_level_interpreter): New function, factored out from captured_main.

20 seconds is far worse. This demonstrates the difficulty of using

/* These three functions support getting lines of text from the user.
They are used in sequence. First deprecated_readline_begin_hook is
called with a text string that might be (for example) a message for
the user to type in a sequence of commands to be executed at a
breakpoint. If this function calls back to a GUI, it might take
this opportunity to pop up a text interaction window with this
message. Next, deprecated_readline_hook is called with a prompt
that is emitted prior to collecting the user input. It can be
called multiple times. Finally, deprecated_readline_end_hook is
called to notify the GUI that we are done with the interaction
window and it can close it. */

void (*deprecated_readline_begin_hook) (char *, ...);
Fix build with Python 3.4 (PR python/16784) The type of the function pointer PyOS_ReadlineFunctionPointer (part of the Python C API), which we use, slightly changed starting with Python 3.4. The signature went from PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, char *); to PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, const char *); The parameter that changed is the prompt text. This commits adjust gdb accordingly by making the prompt_arg parameter const, as well as the fallouts of that. I needed to rework how annotations are added to the prompt, since the it is now const. If annotations are enabled, it will make a copy of the prompt overwrite the prompt variable that is used throughout the function. Otherwise, no copy is done and the original prompt_arg value is passed. I changed the signature of deprecated_readline_hook. I would've changed any user of it, but it seems like nothing is using it, Built-tested with python 2.7.x, 3.3.y and 3.4.z. gdb/ChangeLog: * defs.h (gdb_readline): Constify argument. (gdb_readline_wrapper): Same. (command_line_input): Same. (deprecated_readline_hook): Same. * top.c (deprecated_readline_hook): Same. (gdb_readline): Same. (gdb_readline_wrapper): Same. (command_line_input): Constify argument. Pass prompt to called functions instead of local_prompt, overwriting prompt if using annotations. * event-top.h (display_gdb_prompt): Constify argument. * event-top.c (display_gdb_prompt): Same. * python/py-gdb-readline.c (gdbpy_readline_wrapper): Constify argument if building with Python 3.4 and up.

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.

Add new command to create extra console/mi UIs With all the previous plumbing in place, it's now easy to add a command that actually creates a new console/mi UI. The intended use case is to make it possible and easy for MI frontends to provide a fully featured GDB console to users, with readline support, command line editing, history, etc., just like if gdb was started on the command line. Currently MI frontends have to try to implement all of that theirselves and make use of "-interpreter-exec console ...", which is far from perfect. If you ever tried Eclipse's gdb console window, you'll know what I mean... Instead of trying to multiplex console through MI, this command let's just leverage all the built in readline/editing support already inside gdb. The plan is for the MI frontend to start GDB in regular console mode, running inside a terminal emulator widget embedded in Eclipse (which already exists, for supporting the shell widget; other frontends have similar widgets), and then tell GDB to run a full MI interpreter on an specified input/output device, independent of the console. My original prototype planned to do things the other way around -- start GDB in MI mode, and then start an extra CLI console on separate tty. I handed over that prototype to Marc Khouzam @ Eclipse CDT, and after experimentation and discussion, we ended up concluding that starting GDB in CLI mode instead was both easier and actually also supported an interesting use case -- connect an Eclipse frontend to a GDB that is already running outside Eclipse. The current usage is "new-ui <interpreter> <tty>". E.g., on a terminal run this scriplet: $ cat gdb-client #!/bin/bash reset tty tail -f /dev/null $ gdb-client /dev/pts/15 Now run gdb on another terminal, and tell it to start a MI interpreter on the tty of the other terminal: ... (gdb) new-ui mi /dev/pts/15 New UI allocated Now back to the the gdb-client terminal, we'll get an MI prompt, ready for MI input: /dev/pts/15 =thread-group-added,id="i1" (gdb) You can also start a new UI running a CLI, with: (gdb) new-ui console /dev/pts/15 Though note that this console won't support readline command editing. It works as if "set editing off" was entered. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * interps.c (set_top_level_interpreter): New function, factored out from captured_main.

gdb/17347 - Regression: GDB stopped on run with attached process Doing: gdb --pid=PID -ex run Results in GDB getting a SIGTTIN, and thus ending stopped. That's usually indicative of a missing target_terminal_ours call. E.g., from the PR: $ sleep 1h & p=$!; sleep 0.1; gdb -batch sleep $p -ex run [1] 28263 [1] Killed sleep 1h [2]+ Stopped gdb -batch sleep $p -ex run The workaround is doing: gdb -ex "attach $PID" -ex "run" instead of gdb [-p] $PID -ex "run" With the former, gdb waits for the attach command to complete before moving on to the "run" command, because the interpreter is in sync mode at this point, within execute_command. But for the latter, attach_command is called directly from captured_main, and thus misses that waiting. IOW, "run" is running before the attach continuation has run, before the program stops and attach completes. The broken terminal settings are just one symptom of that. Any command that queries or requires input results in the same. The fix is to wait in catch_command_errors (which is specific to main.c nowadays), just like we wait in execute_command. gdb/ChangeLog: 2014-09-11 Pedro Alves <palves@redhat.com> PR gdb/17347 * main.c: Include "infrun.h".

Replace the sync_execution global with a new enum prompt_state tristate When sync_execution (a boolean) is true, it means we're running a foreground command -- we hide the prompt stop listening to input, give the inferior the terminal, then go to the event loop waiting for the target to stop. With multiple independent UIs, we need to track whether each UI is synchronously blocked waiting for the target. IOW, if you do "continue" in one console, that console stops accepting commands, but you should still be free to type other commands in the others consoles. Just simply making sync_execution be per-UI alone not sufficient, because of this in fetch_inferior_event: /* If the inferior was in sync execution mode, and now isn't, restore the prompt (a synchronous execution command has finished, and we're ready for input). */ if (current_ui->async && was_sync && !sync_execution) observer_notify_sync_execution_done (); We'd have to record at entry the "was_sync" state for each UI, not just of the current UI.

Constify strings in tracepoint.c, lookup_cmd and the completers. This is sort of a continuation of Keith's parse_exp_1 constification patch. It started out by undoing these bits: @@ -754,9 +754,12 @@ validate_actionline (char **line, struct tmp_p = p; for (loc = t->base.loc; loc; loc = loc->next) { - p = tmp_p; - exp = parse_exp_1 (&p, loc->address, + const char *q; + + q = tmp_p; + exp = parse_exp_1 (&q, loc->address, block_for_pc (loc->address), 1); + p = (char *) q; and progressively making more things const upwards, fixing fallout, rinse repeat, until GDB built again (--enable-targets=all). That ended up constifying lookup_cmd/add_cmd and (lots of) friends, and the completers. I didn't try to constify the command hooks themselves, because I know upfront there are commands that write to the command string argument, and I think I managed to stop at a nice non-hacky split point already. I think the only non-really-super-obvious changes are tracepoint.c:validate_actionline, and tracepoint.c:trace_dump_actions. The rest is just mostly about 'char *' => 'const char *', 'char **'=> 'const char **', and the occasional (e.g., deprecated_cmd_warning) case of 'char **'=> 'const char *', where/when I noticed that nothing actually cares about the pointer to pointer output.

Replace the sync_execution global with a new enum prompt_state tristate When sync_execution (a boolean) is true, it means we're running a foreground command -- we hide the prompt stop listening to input, give the inferior the terminal, then go to the event loop waiting for the target to stop. With multiple independent UIs, we need to track whether each UI is synchronously blocked waiting for the target. IOW, if you do "continue" in one console, that console stops accepting commands, but you should still be free to type other commands in the others consoles. Just simply making sync_execution be per-UI alone not sufficient, because of this in fetch_inferior_event: /* If the inferior was in sync execution mode, and now isn't, restore the prompt (a synchronous execution command has finished, and we're ready for input). */ if (current_ui->async && was_sync && !sync_execution) observer_notify_sync_execution_done (); We'd have to record at entry the "was_sync" state for each UI, not just of the current UI. This patch instead replaces the sync_execution flag by a per-UI tristate flag indicating the command line prompt state: enum prompt_state { /* The command line is blocked simulating synchronous execution. This is used to implement the foreground execution commands ('run', 'continue', etc.). We won't display the prompt and accept further commands until the execution is actually over. */ PROMPT_BLOCKED, /* The command finished; display the prompt before returning back to the top level. */ PROMPT_NEEDED, /* We've displayed the prompt already, ready for input. */ PROMPTED, ; I think the end result is _much_ clearer than the current code, and, it addresses the original motivation too. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * annotate.c: Include top.h.

Fix py-finish-breakpoint.exp with target async. With target async enabled, py-finish-breakpoint.exp triggers an assertion failure. The failure occurs because execute_command re-enters the event loop in some circumstances, and in this case resets the sync_execution flag. Then later GDB reaches this assertion in normal_stop: gdb_assert (sync_execution || !target_can_async_p ()); In detail: #1 - A synchronous execution command is run. sync_execution is set. #2 - A python breakpoint is hit (TARGET_WAITKIND_STOPPED), and the corresponding Python breakpoint's stop method is executed. When and while python commands are executed, interpreter_async is forced to 0. #3 - The Python stop method happens to execute a not-execution-related gdb command. In this case, "where 1". #4 - Seeing that sync_execution is set, execute_command nests a new event loop (although that wasn't necessary; this is the problem). #5 - The linux-nat target's pipe in the event loop happens to be marked. That's normal, due to this in linux_nat_wait: /* If we requested any event, and something came out, assume there may be more. If we requested a specific lwp or process, also assume there may be more. */ The nested event loop thus immediately wakes up and calls target_wait. No thread is actually executing in the inferior, so the target returns TARGET_WAITKIND_NO_RESUMED. #6 - normal_stop is reached. GDB prints "No unwaited-for children left.", and resets the sync_execution flag (IOW, there are no resumed threads left, so the synchronous command is considered completed.) This is already bogus. We were handling a breakpoint! #7 - the nested event loop unwinds/ends. GDB is now back to handling the python stop method (TARGET_WAITKIND_STOPPED), which decides the breakpoint should stop. normal_stop is called for this event. However, normal_stop actually works with the _last_ reported target status: void normal_stop (void) { struct target_waitstatus last; ptid_t last_ptid; struct cleanup *old_chain = make_cleanup (null_cleanup, NULL); ... get_last_target_status (&last_ptid, &last); ... if (last.kind == TARGET_WAITKIND_NO_RESUMED) { gdb_assert (sync_execution || !target_can_async_p ()); target_terminal_ours_for_output (); printf_filtered (_("No unwaited-for children left.\n")); } And due to the nesting in execute command, the last event is now TARGET_WAITKIND_NO_RESUMED, not the actual breakpoint event being handled. This could be seen to be broken in itself, but we can leave fixing that for another pass. The assertion is reached, and fails. execute_command has a comment explaining when it should synchronously wait for events: /* If the interpreter is in sync mode (we're running a user command's list, running command hooks or similars), and we just ran a synchronous command that started the target, wait for that command to end. */ However, the code did not follow this comment -- it didn't check to see if the command actually started the target, just whether the target was executing a sync command at this point. This patch fixes the problem by noting whether the target was executing in sync_execution mode before running the command, and then augmenting the condition to test this as well. 2014-03-20 Tom Tromey <tromey@redhat.com> PR gdb/14135 * top.c (execute_command): Only dispatch events if the command started the target.

Constify strings in tracepoint.c, lookup_cmd and the completers. This is sort of a continuation of Keith's parse_exp_1 constification patch. It started out by undoing these bits: @@ -754,9 +754,12 @@ validate_actionline (char **line, struct tmp_p = p; for (loc = t->base.loc; loc; loc = loc->next) { - p = tmp_p; - exp = parse_exp_1 (&p, loc->address, + const char *q; + + q = tmp_p; + exp = parse_exp_1 (&q, loc->address, block_for_pc (loc->address), 1); + p = (char *) q; and progressively making more things const upwards, fixing fallout, rinse repeat, until GDB built again (--enable-targets=all). That ended up constifying lookup_cmd/add_cmd and (lots of) friends, and the completers. I didn't try to constify the command hooks themselves, because I know upfront there are commands that write to the command string argument, and I think I managed to stop at a nice non-hacky split point already. I think the only non-really-super-obvious changes are tracepoint.c:validate_actionline, and tracepoint.c:trace_dump_actions. The rest is just mostly about 'char *' => 'const char *', 'char **'=> 'const char **', and the occasional (e.g., deprecated_cmd_warning) case of 'char **'=> 'const char *', where/when I noticed that nothing actually cares about the pointer to pointer output.

Constify strings in tracepoint.c, lookup_cmd and the completers. This is sort of a continuation of Keith's parse_exp_1 constification patch. It started out by undoing these bits: @@ -754,9 +754,12 @@ validate_actionline (char **line, struct tmp_p = p; for (loc = t->base.loc; loc; loc = loc->next) { - p = tmp_p; - exp = parse_exp_1 (&p, loc->address, + const char *q; + + q = tmp_p; + exp = parse_exp_1 (&q, loc->address, block_for_pc (loc->address), 1); + p = (char *) q; and progressively making more things const upwards, fixing fallout, rinse repeat, until GDB built again (--enable-targets=all). That ended up constifying lookup_cmd/add_cmd and (lots of) friends, and the completers. I didn't try to constify the command hooks themselves, because I know upfront there are commands that write to the command string argument, and I think I managed to stop at a nice non-hacky split point already. I think the only non-really-super-obvious changes are tracepoint.c:validate_actionline, and tracepoint.c:trace_dump_actions. The rest is just mostly about 'char *' => 'const char *', 'char **'=> 'const char **', and the occasional (e.g., deprecated_cmd_warning) case of 'char **'=> 'const char *', where/when I noticed that nothing actually cares about the pointer to pointer output.

gdb/17347 - Regression: GDB stopped on run with attached process Doing: gdb --pid=PID -ex run Results in GDB getting a SIGTTIN, and thus ending stopped. That's usually indicative of a missing target_terminal_ours call. E.g., from the PR: $ sleep 1h & p=$!; sleep 0.1; gdb -batch sleep $p -ex run [1] 28263 [1] Killed sleep 1h [2]+ Stopped gdb -batch sleep $p -ex run The workaround is doing: gdb -ex "attach $PID" -ex "run" instead of gdb [-p] $PID -ex "run" With the former, gdb waits for the attach command to complete before moving on to the "run" command, because the interpreter is in sync mode at this point, within execute_command. But for the latter, attach_command is called directly from captured_main, and thus misses that waiting. IOW, "run" is running before the attach continuation has run, before the program stops and attach completes. The broken terminal settings are just one symptom of that. Any command that queries or requires input results in the same. The fix is to wait in catch_command_errors (which is specific to main.c nowadays), just like we wait in execute_command. gdb/ChangeLog: 2014-09-11 Pedro Alves <palves@redhat.com> PR gdb/17347 * main.c: Include "infrun.h".

/* If we aren't reading from standard input, we are saving the last
thing read from stdin in line and don't want to delete it. Null
lines won't repeat here in any case. */
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. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-script.c (read_next_line): Adjust to per-UI stdin. (read_command_lines): Use input_interactive_p instead of input_from_terminal_p. * defs.h (struct ui): Forward declare. (input_from_terminal_p): Rename to ...

We can't remove that extra event from mingw-hdep.c until we get rid of immediate_quit though. gdb/ChangeLog: 2016-04-12 Pedro Alves <palves@redhat.com> * defs.h: Extend QUIT-related comments to mention interruptible_select. (quit_serial_event_set, quit_serial_event_clear): Declare. * event-top.c: Include "ser-event.h" and "gdb_select.h". (quit_serial_event): New global. (async_init_signals): Make quit_serial_event. (quit_serial_event_set, quit_serial_event_clear) (quit_serial_event_fd, interruptible_select): New functions. * extension.c (set_quit_flag): Set the quit serial event. (check_quit_flag): Clear the quit serial event. * gdb_select.h (interruptible_select): New declaration. * guile/scm-ports.c (ioscm_input_waiting): Use interruptible_select instead of gdb_select. * top.c (gdb_readline_no_editing): Likewise. * ui-file.c (stdio_file_read): Likewise.

Forbid "set history size (INT_MAX..UINT_MAX)" The whole readline interface is signed, and works with the 0..INT_MAX range. We don't allow setting the size to UINT_MAX directly. The documented user visible interface is "use 0 for unlimited". The UINT_MAX representation is an implementation detail we could change, e.g., by keeping a separate flag for "unlimited", which is actually what the readline interface does (stifled vs non stifled). Generically speaking, exposing this detail to clients of the interface may make our lives complicated when we find the need to extend the range of some command in the future, and it's better if users (frontends/scripts) aren't relying on anything but what we tell them to use for "unlimited". Making values other than 0 error out is the way to prevent users from using those ranges inappropriately. Quite related, note: (gdb) set history size 0xffffffff integer 4294967295 out of range But, (gdb) set history size 0xfffffffe (gdb) show history size The size of the command history is unlimited. (gdb) set history size 0x100000000 integer 4294967296 out of range If values over INT_MAX are accepted as unlimited, then there's no good argument for only accepting [INT_MAX..UINT_MAX) as valid "unlimited" magic numbers, while not accepting [UINT_MAX..inf). Making the setting's control variable of different type (unsigned int) of the rest of the related code (int) adds the need to recall that one variable among all these is unsigned, and that one need to think about whether these comparisons are signed or unsigned, along with the promotion/conversion rules. Since this is an easy to forget detail, this patch renames the variable to at least make it more obvious that this variable is not one of GNU history's public int variables, which are all signed. We don't actually need the only code that presently is affected by this, though, the code that is computing the current history's length. We can just use GNU history's history_length instead: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Variable: int history_length The number of entries currently stored in the history list. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /* Return the history entry which is logically at OFFSET in the history array. OFFSET is relative to history_base. */ HIST_ENTRY * history_get (offset) int offset; { int local_index; local_index = offset - history_base; return (local_index >= history_length || local_index < 0 || the_history == 0) ? (HIST_ENTRY *)NULL : the_history[local_index]; } ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ At the time this code was added (gdb 4.13 ~1994), 'history_length' was extern, but not documented in readline's GNU history documents, so I guess it wasn't considered public then and the loop was the workaround. One of the warts of GDB choosing 0 to mean unlimited is that "set history size 0" behaves differently from 'HISTSIZE=0 gdb'. The latter leaves GDB with no history, while the former means "unlimited"... $ HISTSIZE=0 ./gdb ... (gdb) show history size The size of the command history is 0. We shouldn't really change what HISTSIZE=0 means, as bash, etc. also handle 0 as real zero, and zero it's what really makes sense. gdb/ 2013-03-27 Pedro Alves <palves@redhat.com> * top.c (history_size): Rename to ...

/* The variable associated with the "set/show history size"
Fix PR gdb/17820 This patch is a comprehensive fix for PR 17820 which reports that using "set history size unlimited" inside one's gdbinit file doesn't really work. There are three small changes in this patch. The most important change this patch makes is to decode the argument of the "size" subcommand using add_setshow_zuinteger_unlimited_cmd() instead of using add_setshow_uinteger_cmd(). The new decoder takes an int * and maps unlimited to -1 whereas the old decoder takes an unsigned int * and maps unlimited to UINT_MAX. Using the new decoder simplifies our handling of unlimited and makes it easier to interface with readline which itself expects a signed-int history size. The second change is the factoring of the [stifle|unstifle]_history logic into a common function which is now used by both init_history() and set_history_size_command(). This is technically the change that fixes the PR itself. Thirdly, this patch initializes history_size_setshow_var to -2 to mean that the variable has not been set yet. Now init_history() tests for -2 instead of 0 to determine whether to give the variable a default value. This means that having "set history size 0" in one's gdbinit file will actually keep the history size at 0 and not reset it to 256. gdb/ChangeLog: PR gdb/17820 * top.c (history_size_setshow_var): Change type to signed. Initialize to -2. Update documentation. (set_readline_history_size): Define. (set_history_size_command): Use it. Remove logic for handling out-of-range sizes.

/* This is like readline(), but it has some gdb-specific behavior.
gdb may want readline in both the synchronous and async modes during
a single gdb invocation. At the ordinary top-level prompt we might
be using the async readline. That means we can't use
rl_pre_input_hook, since it doesn't work properly in async mode.
However, for a secondary prompt (" >", such as occurs during a
`define'), gdb wants a synchronous response.
We used to call readline() directly, running it in synchronous
mode. But mixing modes this way is not supported, and as of
readline 5.x it no longer works; the arrow keys come unbound during
the synchronous call. So we make a nested call into the event
loop. That's what gdb_readline_wrapper is for. */

reinstall the callback handler, which puts the terminal in raw
mode (or in readline lingo, in prepped state), when we're next
ready to process user input, either in display_gdb_prompt, or if
we're handling an asynchronous target event and running in the

further input (or more target events). */
Make command line editing (use of readline) be per UI Due to the way that readline's API works (based on globals), we can only have one instance of readline in a process. So the goal of this patch is to only allow editing in the main UI, and make sure that only one UI calls into readline. Some MI paths touch readline variables currently, which is bad as that is changing variables that matter for the main console UI. This patch fixes those. This actually fixes a nasty bug -- starting gdb in MI mode ("gdb -i=mi"), and then doing "set editing on" crashes GDB, because MI is not prepared to use readline: set editing on &"set editing on\n" =cmd-param-changed,param="editing",value="on" ^done (gdb) p 1 readline: readline_callback_read_char() called with no handler!

Remove the target from the event loop while in secondary prompts If a pagination prompt triggers while the target is running, and the target exits before the user responded to the pagination query, this happens: Starting program: foo ---Type <return> to continue, or q <return> to quit---No unwaited-for children left. Couldn't get registers: No such process. Couldn't get registers: No such process. Couldn't get registers: No such process. (gdb) Couldn't get registers: No such process. (gdb) To reiterate, the user hasn't replied to the pagination prompt above. A pagination query nests an event loop (in gdb_readline_wrapper). In async mode, in addition to stdin and signal handlers, we'll have the target also installed in the event loop still. So if the target reports an event, that wakes up the nested event loop, which calls into fetch_inferior_event etc. to handle the event which generates further output, all while we should be waiting for pagination confirmation... (TBC, any target event that generates output ends up spuriously waking up the pagination, though exits seem to be the worse kind.) I've played with a couple different approaches to fixing this, while at the same time trying to avoid being invasive. Both revolve around not listening to target events while in a pagination prompt (doing anything else I think would be a much bigger change). The approach taken just removes the target from the event loop while within gdb_readline_wrapper. The other approach used gdb_select directly, with only input_fd installed, but that had the issue that it didn't handle the async signal handlers, and turned out to be a bit more code than the first version. gdb/ 2014-07-14 Pedro Alves <palves@redhat.com> PR gdb/17072 * top.c: Include "inf-loop.h".

Introduce "struct ui" This is a step towards supporting multiple consoles/MIs, each on its own stdio streams / terminal. See intro comment in top.h. (I've had trouble picking a name for this object. I've started out with "struct console" originally. But then this is about MI as well, and there's "interpreter-exec console", which is specifically about the CLI... So I changed to "struct terminal", but, then we have a terminal object that works when the input is not a terminal as well ... Then I sort of gave up and renamed it to "struct top_level". But it then gets horribly confusing when we talk about the "top level interpreter that's running on the current top level".

Make command line editing (use of readline) be per UI Due to the way that readline's API works (based on globals), we can only have one instance of readline in a process. So the goal of this patch is to only allow editing in the main UI, and make sure that only one UI calls into readline. Some MI paths touch readline variables currently, which is bad as that is changing variables that matter for the main console UI. This patch fixes those. This actually fixes a nasty bug -- starting gdb in MI mode ("gdb -i=mi"), and then doing "set editing on" crashes GDB, because MI is not prepared to use readline: set editing on &"set editing on\n" =cmd-param-changed,param="editing",value="on" ^done (gdb) p 1 readline: readline_callback_read_char() called with no handler!

Introduce "struct ui" This is a step towards supporting multiple consoles/MIs, each on its own stdio streams / terminal. See intro comment in top.h. (I've had trouble picking a name for this object. I've started out with "struct console" originally. But then this is about MI as well, and there's "interpreter-exec console", which is specifically about the CLI... So I changed to "struct terminal", but, then we have a terminal object that works when the input is not a terminal as well ... Then I sort of gave up and renamed it to "struct top_level". But it then gets horribly confusing when we talk about the "top level interpreter that's running on the current top level". In the end, I realized we're already sort of calling this "ui", in struct ui_out, struct ui_file, and a few coments here and there.) gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * event-top.c: Update readline-related comments.

But if the output is coming out of handling a stop event, we don't re-display the prompt, and nothing restores the handler. So the next input wakes up the event loop and calls into readline, which aborts. We should do better with the prompt handling while the target is running (I think we should coordinate with readline, and hide/redisplay it around output), but that's a more invasive change better done post 7.8, so this patch is conservative and just reinstalls the handler as soon as we're out of the readline line callback. gdb/ 2014-07-14 Pedro Alves <palves@redhat.com> PR gdb/17072 * top.c (gdb_readline_wrapper_line): Tweak comment.

The problem is that installing the input handler callback also preps the terminal, putting it in raw mode and with echo disabled, which is bad if we're going to call a command that assumes cooked/canonical mode, and echo enabled, like in the case of the PR, Python's interactive shell. Another example I came up with that doesn't depend on Python is starting a subshell with "(gdb) shell /bin/sh" from a multi-line command. Tests covering both these examples are added. The fix is to revert the original fix for PR gdb/17072, and instead restore the callback handler after processing an asynchronous target event. Furthermore, calling rl_callback_handler_install when we already have some input in readline's line buffer discards that input, which is obviously a bad thing to do while the user is typing. No specific test is added for that, because I first tried calling it even if the callback handler was still installed and that resulted in hundreds of failures in the testsuite. gdb/ 2014-10-29 Pedro Alves <palves@redhat.com> PR python/17372 * event-top.c (change_line_handler): Call gdb_rl_callback_handler_remove instead of rl_callback_handler_remove.

Background execution + pagination aborts readline/gdb If pagination occurs as result of output sent as response to a target event while the target is executing in the background, subsequent input aborts readline/gdb: $ gdb program ... (gdb) continue& Continuing. (gdb) ---Type <return> to continue, or q <return> to quit--- *return* ---Type <return> to continue, or q <return> to quit--- Breakpoint 2, after_sleep () at paginate-bg-execution.c:21 ---Type <return> to continue, or q <return> to quit--- 21 return; /* after sleep */ p 1 readline: readline_callback_read_char() called with no handler! *abort/SIGABRT* $ gdb_readline_wrapper_line removes the handler after a line is processed. Usually, we'll end up re-displaying the prompt, and that reinstalls the handler. But if the output is coming out of handling a stop event, we don't re-display the prompt, and nothing restores the handler. So the next input wakes up the event loop and calls into readline, which aborts. We should do better with the prompt handling while the target is running (I think we should coordinate with readline, and hide/redisplay it around output), but that's a more invasive change better done post 7.8, so this patch is conservative and just reinstalls the handler as soon as we're out of the readline line callback. gdb/ 2014-07-14 Pedro Alves <palves@redhat.com> PR gdb/17072 * top.c (gdb_readline_wrapper_line): Tweak comment.

Remove the target from the event loop while in secondary prompts If a pagination prompt triggers while the target is running, and the target exits before the user responded to the pagination query, this happens: Starting program: foo ---Type <return> to continue, or q <return> to quit---No unwaited-for children left.

In async mode, in addition to stdin and signal handlers, we'll have the target also installed in the event loop still.

Simplify target_async hook interface All callers of target_async pass it the same callback (inferior_event_handler). Since both common code and target backends need to be able to put the target in and out of target async mode at any given time, there's really no way that a different callback could be passed. This commit simplifies things, and removes the indirection altogether. Bonus: with this, gdb's target_async method ends up with the same signature as gdbserver's.

Fix build with Python 3.4 (PR python/16784) The type of the function pointer PyOS_ReadlineFunctionPointer (part of the Python C API), which we use, slightly changed starting with Python 3.4. The signature went from PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, char *); to PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, const char *); The parameter that changed is the prompt text. This commits adjust gdb accordingly by making the prompt_arg parameter const, as well as the fallouts of that. I needed to rework how annotations are added to the prompt, since the it is now const. If annotations are enabled, it will make a copy of the prompt overwrite the prompt variable that is used throughout the function. Otherwise, no copy is done and the original prompt_arg value is passed. I changed the signature of deprecated_readline_hook. I would've changed any user of it, but it seems like nothing is using it, Built-tested with python 2.7.x, 3.3.y and 3.4.z. gdb/ChangeLog: * defs.h (gdb_readline): Constify argument.

Introduce "struct ui" This is a step towards supporting multiple consoles/MIs, each on its own stdio streams / terminal. See intro comment in top.h. (I've had trouble picking a name for this object. I've started out with "struct console" originally. But then this is about MI as well, and there's "interpreter-exec console", which is specifically about the CLI... So I changed to "struct terminal", but, then we have a terminal object that works when the input is not a terminal as well ... Then I sort of gave up and renamed it to "struct top_level". But it then gets horribly confusing when we talk about the "top level interpreter that's running on the current top level". In the end, I realized we're already sort of calling this "ui", in struct ui_out, struct ui_file, and a few coments here and there.) gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * event-top.c: Update readline-related comments.

Replace some xmalloc-family functions with XNEW-family ones This patch is part of the make-gdb-buildable-in-C++ effort. The idea is to change some calls to the xmalloc family of functions to calls to the equivalents in the XNEW family. This avoids adding an explicit cast, so it keeps the code a bit more readable. Some of them also map relatively well to a C++ equivalent (XNEW (struct foo) -> new foo), so it will be possible to do scripted replacements if needed. I only changed calls that were obviously allocating memory for one or multiple "objects". Allocation of variable sizes (such as strings or buffer handling) will be for later (and won't use XNEW). - xmalloc (sizeof (struct foo)) -> XNEW (struct foo) - xmalloc (num * sizeof (struct foo)) -> XNEWVEC (struct foo, num) - xcalloc (1, sizeof (struct foo)) -> XCNEW (struct foo) - xcalloc (num, sizeof (struct foo)) -> XCNEWVEC (struct foo, num) - xrealloc (p, num * sizeof (struct foo) -> XRESIZEVEC (struct foo, p, num) - obstack_alloc (ob, sizeof (struct foo)) -> XOBNEW (ob, struct foo) - obstack_alloc (ob, num * sizeof (struct foo)) -> XOBNEWVEC (ob, struct foo, num) - alloca (sizeof (struct foo)) -> XALLOCA (struct foo) - alloca (num * sizeof (struct foo)) -> XALLOCAVEC (struct foo, num) Some instances of xmalloc followed by memset to zero the buffer were replaced by XCNEW or XCNEWVEC. I regtested on x86-64, Ubuntu 14.04, but the patch touches many architecture-specific files. For those I'll have to rely on the buildbot or people complaining that I broke their gdb. gdb/ChangeLog: * aarch64-linux-nat.c (aarch64_add_process): Likewise. * aarch64-tdep.c (aarch64_gdbarch_init): Likewise. * ada-exp.y (write_ambiguous_var): Likewise. * ada-lang.c (resolve_subexp): Likewise.

Introduce "struct ui" This is a step towards supporting multiple consoles/MIs, each on its own stdio streams / terminal. See intro comment in top.h. (I've had trouble picking a name for this object. I've started out with "struct console" originally. But then this is about MI as well, and there's "interpreter-exec console", which is specifically about the CLI... So I changed to "struct terminal", but, then we have a terminal object that works when the input is not a terminal as well ... Then I sort of gave up and renamed it to "struct top_level". But it then gets horribly confusing when we talk about the "top level interpreter that's running on the current top level". In the end, I realized we're already sort of calling this "ui", in struct ui_out, struct ui_file, and a few coments here and there.) gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * event-top.c: Update readline-related comments.

Make command line editing (use of readline) be per UI Due to the way that readline's API works (based on globals), we can only have one instance of readline in a process. So the goal of this patch is to only allow editing in the main UI, and make sure that only one UI calls into readline. Some MI paths touch readline variables currently, which is bad as that is changing variables that matter for the main console UI. This patch fixes those. This actually fixes a nasty bug -- starting gdb in MI mode ("gdb -i=mi"), and then doing "set editing on" crashes GDB, because MI is not prepared to use readline: set editing on &"set editing on\n" =cmd-param-changed,param="editing",value="on" ^done (gdb) p 1 readline: readline_callback_read_char() called with no handler!

Remove the target from the event loop while in secondary prompts If a pagination prompt triggers while the target is running, and the target exits before the user responded to the pagination query, this happens: Starting program: foo ---Type <return> to continue, or q <return> to quit---No unwaited-for children left. Couldn't get registers: No such process. Couldn't get registers: No such process. Couldn't get registers: No such process. (gdb) Couldn't get registers: No such process. (gdb) To reiterate, the user hasn't replied to the pagination prompt above. A pagination query nests an event loop (in gdb_readline_wrapper). In async mode, in addition to stdin and signal handlers, we'll have the target also installed in the event loop still. So if the target reports an event, that wakes up the nested event loop, which calls into fetch_inferior_event etc. to handle the event which generates further output, all while we should be waiting for pagination confirmation... (TBC, any target event that generates output ends up spuriously waking up the pagination, though exits seem to be the worse kind.) I've played with a couple different approaches to fixing this, while at the same time trying to avoid being invasive. Both revolve around not listening to target events while in a pagination prompt (doing anything else I think would be a much bigger change). The approach taken just removes the target from the event loop while within gdb_readline_wrapper. The other approach used gdb_select directly, with only input_fd installed, but that had the issue that it didn't handle the async signal handlers, and turned out to be a bit more code than the first version. gdb/ 2014-07-14 Pedro Alves <palves@redhat.com> PR gdb/17072 * top.c: Include "inf-loop.h".

Simplify target_async hook interface All callers of target_async pass it the same callback (inferior_event_handler). Since both common code and target backends need to be able to put the target in and out of target async mode at any given time, there's really no way that a different callback could be passed. This commit simplifies things, and removes the indirection altogether. Bonus: with this, gdb's target_async method ends up with the same signature as gdbserver's.

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. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-script.c (read_next_line): Adjust to per-UI stdin.

Otherwise, no copy is done and the original prompt_arg value is passed. I changed the signature of deprecated_readline_hook.

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. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-script.c (read_next_line): Adjust to per-UI stdin.

Fix build with Python 3.4 (PR python/16784) The type of the function pointer PyOS_ReadlineFunctionPointer (part of the Python C API), which we use, slightly changed starting with Python 3.4. The signature went from PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, char *); to PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, const char *); The parameter that changed is the prompt text. This commits adjust gdb accordingly by making the prompt_arg parameter const, as well as the fallouts of that. I needed to rework how annotations are added to the prompt, since the it is now const. If annotations are enabled, it will make a copy of the prompt overwrite the prompt variable that is used throughout the function. Otherwise, no copy is done and the original prompt_arg value is passed. I changed the signature of deprecated_readline_hook. I would've changed any user of it, but it seems like nothing is using it, Built-tested with python 2.7.x, 3.3.y and 3.4.z. gdb/ChangeLog: * defs.h (gdb_readline): Constify argument. (gdb_readline_wrapper): Same. (command_line_input): Same. (deprecated_readline_hook): Same. * top.c (deprecated_readline_hook): Same. (gdb_readline): Same. (gdb_readline_wrapper): Same. (command_line_input): Constify argument. Pass prompt to called functions instead of local_prompt, overwriting prompt if using annotations. * event-top.h (display_gdb_prompt): Constify argument. * event-top.c (display_gdb_prompt): Same. * python/py-gdb-readline.c (gdbpy_readline_wrapper): Constify argument if building with Python 3.4 and up.

Add casts to memory allocation related calls Most allocation functions (if not all) return a void* pointing to the allocated memory. In C++, we need to add an explicit cast when assigning the result to a pointer to another type (which is the case more often than not). The content of this patch is taken from Pedro's branch, from commit "(mostly) auto-generated patch to insert casts needed for C++". I validated that the changes make sense and manually reflowed the code to make it respect the coding style. I also found multiple places where I could use XNEW/XNEWVEC/XRESIZEVEC/etc. Thanks a lot to whoever did that automated script to insert casts, doing it completely by hand would have taken a ridiculous amount of time. Only files built on x86 with --enable-targets=all are modified. This means that all other -nat.c files are untouched and will have to be dealt with later by using appropiate compilers. Or maybe we can try to build them with a regular g++ just to know where to add casts, I don't know. I built-tested this with --enable-targets=all and reg-tested. Here's the changelog entry, which was not too bad to make despite the size, thanks to David Malcom's script.

Fix build with Python 3.4 (PR python/16784) The type of the function pointer PyOS_ReadlineFunctionPointer (part of the Python C API), which we use, slightly changed starting with Python 3.4. The signature went from PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, char *); to PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, const char *); The parameter that changed is the prompt text. This commits adjust gdb accordingly by making the prompt_arg parameter const, as well as the fallouts of that. I needed to rework how annotations are added to the prompt, since the it is now const. If annotations are enabled, it will make a copy of the prompt overwrite the prompt variable that is used throughout the function. Otherwise, no copy is done and the original prompt_arg value is passed. I changed the signature of deprecated_readline_hook.

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. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-script.c (read_next_line): Adjust to per-UI stdin.

Fix build with Python 3.4 (PR python/16784) The type of the function pointer PyOS_ReadlineFunctionPointer (part of the Python C API), which we use, slightly changed starting with Python 3.4. The signature went from PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, char *); to PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, const char *); The parameter that changed is the prompt text. This commits adjust gdb accordingly by making the prompt_arg parameter const, as well as the fallouts of that. I needed to rework how annotations are added to the prompt, since the it is now const. If annotations are enabled, it will make a copy of the prompt overwrite the prompt variable that is used throughout the function. Otherwise, no copy is done and the original prompt_arg value is passed. I changed the signature of deprecated_readline_hook.

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. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-script.c (read_next_line): Adjust to per-UI stdin.

Fix build with Python 3.4 (PR python/16784) The type of the function pointer PyOS_ReadlineFunctionPointer (part of the Python C API), which we use, slightly changed starting with Python 3.4. The signature went from PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, char *); to PyAPI_DATA(char) *(*PyOS_ReadlineFunctionPointer)(FILE *, FILE *, const char *); The parameter that changed is the prompt text. This commits adjust gdb accordingly by making the prompt_arg parameter const, as well as the fallouts of that. I needed to rework how annotations are added to the prompt, since the it is now const. If annotations are enabled, it will make a copy of the prompt overwrite the prompt variable that is used throughout the function. Otherwise, no copy is done and the original prompt_arg value is passed. I changed the signature of deprecated_readline_hook. I would've changed any user of it, but it seems like nothing is using it, Built-tested with python 2.7.x, 3.3.y and 3.4.z. gdb/ChangeLog: * defs.h (gdb_readline): Constify argument. (gdb_readline_wrapper): Same. (command_line_input): Same. (deprecated_readline_hook): Same. * top.c (deprecated_readline_hook): Same. (gdb_readline): Same. (gdb_readline_wrapper): Same. (command_line_input): Constify argument. Pass prompt to called functions instead of local_prompt, overwriting prompt if using annotations. * event-top.h (display_gdb_prompt): Constify argument. * event-top.c (display_gdb_prompt): Same. * python/py-gdb-readline.c (gdbpy_readline_wrapper): Constify argument if building with Python 3.4 and up.

Make command line editing (use of readline) be per UI Due to the way that readline's API works (based on globals), we can only have one instance of readline in a process.

make -gdb-exit call disconnect_tracing too, and don't lose history if the target errors on "quit" Gareth mentions in PR gdb/15275: "The MI '-gdb-exit' command mi_cmd_gdb_exit() never calls disconnect_tracing() and therefore exits correctly." It should, so to get out of tfind mode, as quit may detach instead of kill, and we don't want to confuse the memory/register accesses etc. of the detach process.

/* Get out of tfind mode, and kill or detach all inferiors. */
Split TRY_CATCH into TRY + CATCH This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here. CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH Just like it isn't valid to do that with C++'s native try/catch. By switching to creating the exception object inside the CATCH block scope, we can get rid of all the explicitly allocated volatile exception objects all over the tree, and map the CATCH block more directly to C++'s catch blocks. The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was done with a script, rerun from scratch at every rebase, no manual editing involved. After the mechanical conversion, a few places needed manual intervention, to fix preexisting cases where we were using the exception object outside of the TRY_CATCH block, and cases where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH after this patch]. The result was folded into this patch so that GDB still builds at each incremental step. END_CATCH is necessary for two reasons: First, because we name the exception object in the CATCH block, which requires creating a scope, which in turn must be closed somewhere. Declaring the exception variable in the initializer field of a for block, like: #define CATCH(EXCEPTION, mask) \ for (struct gdb_exception EXCEPTION; \ exceptions_state_mc_catch (&EXCEPTION, MASK); \ EXCEPTION = exception_none) would avoid needing END_CATCH, but alas, in C mode, we build with C90, which doesn't allow mixed declarations and code. Second, because when TRY/CATCH are wired to real C++ try/catch, as long as we need to handle cleanup chains, even if there's no CATCH block that wants to catch the exception, we need for stop at every frame in the unwind chain and run cleanups, then rethrow. That will be done in END_CATCH. After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist. IMO, this still makes the TRY/CATCH code look a bit more like a newcomer would expect, so IMO worth it even if we weren't considering C++. gdb/ChangeLog. 2015-03-07 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (struct catcher) <exception>: No longer a pointer to volatile exception.

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. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-script.c (read_next_line): Adjust to per-UI stdin.

make -gdb-exit call disconnect_tracing too, and don't lose history if the target errors on "quit" Gareth mentions in PR gdb/15275: "The MI '-gdb-exit' command mi_cmd_gdb_exit() never calls disconnect_tracing() and therefore exits correctly."

So we should push down the disconnect tracing bits at least to quit_force. But we can't as is, as that would swallow the error thrown by answering "no" to: Trace is running but will stop on detach; detach anyway?

Split TRY_CATCH into TRY + CATCH This patch splits the TRY_CATCH macro into three, so that we go from this: ~~~ volatile gdb_exception ex; TRY_CATCH (ex, RETURN_MASK_ERROR) { } if (ex.reason < 0) { } ~~~ to this: ~~~ TRY { } CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH ~~~ Thus, we'll be getting rid of the local volatile exception object, and declaring the caught exception in the catch block. This allows reimplementing TRY/CATCH in terms of C++ exceptions when building in C++ mode, while still allowing to build GDB in C mode (using setjmp/longjmp), as a transition step. TBC, after this patch, is it _not_ valid to have code between the TRY and the CATCH blocks, like: TRY { } // some code here. CATCH (ex, RETURN_MASK_ERROR) { } END_CATCH Just like it isn't valid to do that with C++'s native try/catch. By switching to creating the exception object inside the CATCH block scope, we can get rid of all the explicitly allocated volatile exception objects all over the tree, and map the CATCH block more directly to C++'s catch blocks. The majority of the TRY_CATCH -> TRY+CATCH+END_CATCH conversion was done with a script, rerun from scratch at every rebase, no manual editing involved. After the mechanical conversion, a few places needed manual intervention, to fix preexisting cases where we were using the exception object outside of the TRY_CATCH block, and cases where we were using "else" after a 'if (ex.reason) < 0)' [a CATCH after this patch]. The result was folded into this patch so that GDB still builds at each incremental step. END_CATCH is necessary for two reasons: First, because we name the exception object in the CATCH block, which requires creating a scope, which in turn must be closed somewhere. Declaring the exception variable in the initializer field of a for block, like: #define CATCH(EXCEPTION, mask) \ for (struct gdb_exception EXCEPTION; \ exceptions_state_mc_catch (&EXCEPTION, MASK); \ EXCEPTION = exception_none) would avoid needing END_CATCH, but alas, in C mode, we build with C90, which doesn't allow mixed declarations and code. Second, because when TRY/CATCH are wired to real C++ try/catch, as long as we need to handle cleanup chains, even if there's no CATCH block that wants to catch the exception, we need for stop at every frame in the unwind chain and run cleanups, then rethrow. That will be done in END_CATCH. After we require C++, we'll still need TRY/CATCH/END_CATCH until cleanups are completely phased out -- TRY/CATCH in C++ mode will save/restore the current cleanup chain, like in C mode, and END_CATCH catches otherwise uncaugh exceptions, runs cleanups and rethrows, so that C++ cleanups and exceptions can coexist. IMO, this still makes the TRY/CATCH code look a bit more like a newcomer would expect, so IMO worth it even if we weren't considering C++. gdb/ChangeLog. 2015-03-07 Pedro Alves <palves@redhat.com> * common/common-exceptions.c (struct catcher) <exception>: No longer a pointer to volatile exception.

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.

Fix PR gdb/17820 This patch is a comprehensive fix for PR 17820 which reports that using "set history size unlimited" inside one's gdbinit file doesn't really work. There are three small changes in this patch. The most important change this patch makes is to decode the argument of the "size" subcommand using add_setshow_zuinteger_unlimited_cmd() instead of using add_setshow_uinteger_cmd(). The new decoder takes an int * and maps unlimited to -1 whereas the old decoder takes an unsigned int * and maps unlimited to UINT_MAX. Using the new decoder simplifies our handling of unlimited and makes it easier to interface with readline which itself expects a signed-int history size. The second change is the factoring of the [stifle|unstifle]_history logic into a common function which is now used by both init_history() and set_history_size_command(). This is technically the change that fixes the PR itself. Thirdly, this patch initializes history_size_setshow_var to -2 to mean that the variable has not been set yet. Now init_history() tests for -2 instead of 0 to determine whether to give the variable a default value. This means that having "set history size 0" in one's gdbinit file will actually keep the history size at 0 and not reset it to 256. gdb/ChangeLog: PR gdb/17820 * top.c (history_size_setshow_var): Change type to signed. Initialize to -2. Update documentation. (set_readline_history_size): Define. (set_history_size_command): Use it. Remove logic for handling out-of-range sizes.

/* Update the size of our command history file to HISTORY_SIZE.
Forbid "set history size (INT_MAX..UINT_MAX)" The whole readline interface is signed, and works with the 0..INT_MAX range. We don't allow setting the size to UINT_MAX directly. The documented user visible interface is "use 0 for unlimited". The UINT_MAX representation is an implementation detail we could change, e.g., by keeping a separate flag for "unlimited", which is actually what the readline interface does (stifled vs non stifled). Generically speaking, exposing this detail to clients of the interface may make our lives complicated when we find the need to extend the range of some command in the future, and it's better if users (frontends/scripts) aren't relying on anything but what we tell them to use for "unlimited". Making values other than 0 error out is the way to prevent users from using those ranges inappropriately. Quite related, note: (gdb) set history size 0xffffffff integer 4294967295 out of range But, (gdb) set history size 0xfffffffe (gdb) show history size The size of the command history is unlimited. (gdb) set history size 0x100000000 integer 4294967296 out of range If values over INT_MAX are accepted as unlimited, then there's no good argument for only accepting [INT_MAX..UINT_MAX) as valid "unlimited" magic numbers, while not accepting [UINT_MAX..inf). Making the setting's control variable of different type (unsigned int) of the rest of the related code (int) adds the need to recall that one variable among all these is unsigned, and that one need to think about whether these comparisons are signed or unsigned, along with the promotion/conversion rules. Since this is an easy to forget detail, this patch renames the variable to at least make it more obvious that this variable is not one of GNU history's public int variables, which are all signed. We don't actually need the only code that presently is affected by this, though, the code that is computing the current history's length. We can just use GNU history's history_length instead: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Variable: int history_length The number of entries currently stored in the history list. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /* Return the history entry which is logically at OFFSET in the history array. OFFSET is relative to history_base. */ HIST_ENTRY * history_get (offset) int offset; { int local_index; local_index = offset - history_base; return (local_index >= history_length || local_index < 0 || the_history == 0) ?

The latter leaves GDB with no history, while the former means "unlimited"... $ HISTSIZE=0 ./gdb ... (gdb) show history size The size of the command history is 0.

make calls to help_list use enumerator Currently there are many calls to help_list that pass the constant -1 as the "class" value.

Constify strings in tracepoint.c, lookup_cmd and the completers. This is sort of a continuation of Keith's parse_exp_1 constification patch. It started out by undoing these bits: @@ -754,9 +754,12 @@ validate_actionline (char **line, struct tmp_p = p; for (loc = t->base.loc; loc; loc = loc->next) { - p = tmp_p; - exp = parse_exp_1 (&p, loc->address, + const char *q; + + q = tmp_p; + exp = parse_exp_1 (&q, loc->address, block_for_pc (loc->address), 1); + p = (char *) q; and progressively making more things const upwards, fixing fallout, rinse repeat, until GDB built again (--enable-targets=all). That ended up constifying lookup_cmd/add_cmd and (lots of) friends, and the completers. I didn't try to constify the command hooks themselves, because I know upfront there are commands that write to the command string argument, and I think I managed to stop at a nice non-hacky split point already. I think the only non-really-super-obvious changes are tracepoint.c:validate_actionline, and tracepoint.c:trace_dump_actions. The rest is just mostly about 'char *' => 'const char *', 'char **'=> 'const char **', and the occasional (e.g., deprecated_cmd_warning) case of 'char **'=> 'const char *', where/when I noticed that nothing actually cares about the pointer to pointer output.

Forbid "set history size (INT_MAX..UINT_MAX)" The whole readline interface is signed, and works with the 0..INT_MAX range. We don't allow setting the size to UINT_MAX directly. The documented user visible interface is "use 0 for unlimited". The UINT_MAX representation is an implementation detail we could change, e.g., by keeping a separate flag for "unlimited", which is actually what the readline interface does (stifled vs non stifled). Generically speaking, exposing this detail to clients of the interface may make our lives complicated when we find the need to extend the range of some command in the future, and it's better if users (frontends/scripts) aren't relying on anything but what we tell them to use for "unlimited". Making values other than 0 error out is the way to prevent users from using those ranges inappropriately. Quite related, note: (gdb) set history size 0xffffffff integer 4294967295 out of range But, (gdb) set history size 0xfffffffe (gdb) show history size The size of the command history is unlimited. (gdb) set history size 0x100000000 integer 4294967296 out of range If values over INT_MAX are accepted as unlimited, then there's no good argument for only accepting [INT_MAX..UINT_MAX) as valid "unlimited" magic numbers, while not accepting [UINT_MAX..inf). Making the setting's control variable of different type (unsigned int) of the rest of the related code (int) adds the need to recall that one variable among all these is unsigned, and that one need to think about whether these comparisons are signed or unsigned, along with the promotion/conversion rules. Since this is an easy to forget detail, this patch renames the variable to at least make it more obvious that this variable is not one of GNU history's public int variables, which are all signed. We don't actually need the only code that presently is affected by this, though, the code that is computing the current history's length. We can just use GNU history's history_length instead: ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Variable: int history_length The number of entries currently stored in the history list. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ /* Return the history entry which is logically at OFFSET in the history array. OFFSET is relative to history_base. */ HIST_ENTRY * history_get (offset) int offset; { int local_index; local_index = offset - history_base; return (local_index >= history_length || local_index < 0 || the_history == 0) ?

Fix PR gdb/17820 This patch is a comprehensive fix for PR 17820 which reports that using "set history size unlimited" inside one's gdbinit file doesn't really work. There are three small changes in this patch. The most important change this patch makes is to decode the argument of the "size" subcommand using add_setshow_zuinteger_unlimited_cmd() instead of using add_setshow_uinteger_cmd(). The new decoder takes an int * and maps unlimited to -1 whereas the old decoder takes an unsigned int * and maps unlimited to UINT_MAX. Using the new decoder simplifies our handling of unlimited and makes it easier to interface with readline which itself expects a signed-int history size. The second change is the factoring of the [stifle|unstifle]_history logic into a common function which is now used by both init_history() and set_history_size_command(). This is technically the change that fixes the PR itself. Thirdly, this patch initializes history_size_setshow_var to -2 to mean that the variable has not been set yet. Now init_history() tests for -2 instead of 0 to determine whether to give the variable a default value. This means that having "set history size 0" in one's gdbinit file will actually keep the history size at 0 and not reset it to 256. gdb/ChangeLog: PR gdb/17820 * top.c (history_size_setshow_var): Change type to signed. Initialize to -2. Update documentation. (set_readline_history_size): Define. (set_history_size_command): Use it. Remove logic for handling out-of-range sizes. (init_history): Use set_readline_history_size(). Test for a value of -2 instead of 0 when determining whether to set a default history size.

Make command line editing (use of readline) be per UI Due to the way that readline's API works (based on globals), we can only have one instance of readline in a process. So the goal of this patch is to only allow editing in the main UI, and make sure that only one UI calls into readline. Some MI paths touch readline variables currently, which is bad as that is changing variables that matter for the main console UI. This patch fixes those. This actually fixes a nasty bug -- starting gdb in MI mode ("gdb -i=mi"), and then doing "set editing on" crashes GDB, because MI is not prepared to use readline: set editing on &"set editing on\n" =cmd-param-changed,param="editing",value="on" ^done (gdb) p 1 readline: readline_callback_read_char() called with no handler!

Make command line editing (use of readline) be per UI Due to the way that readline's API works (based on globals), we can only have one instance of readline in a process. So the goal of this patch is to only allow editing in the main UI, and make sure that only one UI calls into readline. Some MI paths touch readline variables currently, which is bad as that is changing variables that matter for the main console UI. This patch fixes those. This actually fixes a nasty bug -- starting gdb in MI mode ("gdb -i=mi"), and then doing "set editing on" crashes GDB, because MI is not prepared to use readline: set editing on &"set editing on\n" =cmd-param-changed,param="editing",value="on" ^done (gdb) p 1 readline: readline_callback_read_char() called with no handler!

Add new command to create extra console/mi UIs With all the previous plumbing in place, it's now easy to add a command that actually creates a new console/mi UI. The intended use case is to make it possible and easy for MI frontends to provide a fully featured GDB console to users, with readline support, command line editing, history, etc., just like if gdb was started on the command line. Currently MI frontends have to try to implement all of that theirselves and make use of "-interpreter-exec console ...", which is far from perfect. If you ever tried Eclipse's gdb console window, you'll know what I mean... Instead of trying to multiplex console through MI, this command let's just leverage all the built in readline/editing support already inside gdb. The plan is for the MI frontend to start GDB in regular console mode, running inside a terminal emulator widget embedded in Eclipse (which already exists, for supporting the shell widget; other frontends have similar widgets), and then tell GDB to run a full MI interpreter on an specified input/output device, independent of the console. My original prototype planned to do things the other way around -- start GDB in MI mode, and then start an extra CLI console on separate tty. I handed over that prototype to Marc Khouzam @ Eclipse CDT, and after experimentation and discussion, we ended up concluding that starting GDB in CLI mode instead was both easier and actually also supported an interesting use case -- connect an Eclipse frontend to a GDB that is already running outside Eclipse. The current usage is "new-ui <interpreter> <tty>". E.g., on a terminal run this scriplet: $ cat gdb-client #!/bin/bash reset tty tail -f /dev/null $ gdb-client /dev/pts/15 Now run gdb on another terminal, and tell it to start a MI interpreter on the tty of the other terminal: ... (gdb) new-ui mi /dev/pts/15 New UI allocated Now back to the the gdb-client terminal, we'll get an MI prompt, ready for MI input: /dev/pts/15 =thread-group-added,id="i1" (gdb) You can also start a new UI running a CLI, with: (gdb) new-ui console /dev/pts/15 Though note that this console won't support readline command editing. It works as if "set editing off" was entered. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * interps.c (set_top_level_interpreter): New function, factored out from captured_main.

Fix PR gdb/17820 This patch is a comprehensive fix for PR 17820 which reports that using "set history size unlimited" inside one's gdbinit file doesn't really work. There are three small changes in this patch. The most important change this patch makes is to decode the argument of the "size" subcommand using add_setshow_zuinteger_unlimited_cmd() instead of using add_setshow_uinteger_cmd(). The new decoder takes an int * and maps unlimited to -1 whereas the old decoder takes an unsigned int * and maps unlimited to UINT_MAX. Using the new decoder simplifies our handling of unlimited and makes it easier to interface with readline which itself expects a signed-int history size. The second change is the factoring of the [stifle|unstifle]_history logic into a common function which is now used by both init_history() and set_history_size_command(). This is technically the change that fixes the PR itself. Thirdly, this patch initializes history_size_setshow_var to -2 to mean that the variable has not been set yet. Now init_history() tests for -2 instead of 0 to determine whether to give the variable a default value. This means that having "set history size 0" in one's gdbinit file will actually keep the history size at 0 and not reset it to 256. gdb/ChangeLog: PR gdb/17820 * top.c (history_size_setshow_var): Change type to signed. Initialize to -2. Update documentation. (set_readline_history_size): Define. (set_history_size_command): Use it. Remove logic for handling out-of-range sizes. (init_history): Use set_readline_history_size(). Test for a value of -2 instead of 0 when determining whether to set a default history size.

Accept "set foo unlimited" in integer/uinteger/zuinteger_unlimited commands. Currently, several commands take "0" or "-1" to mean "unlimited". "show" knows when to print "unlimited": (gdb) show height Number of lines gdb thinks are in a page is 45. (gdb) set height 0 (gdb) show height Number of lines gdb thinks are in a page is unlimited. However, the user can't herself specify "unlimited" directly: (gdb) set height unlimited No symbol table is loaded. Use the "file" command. (gdb) This patch addresses that, by adjusting the set handler for all integer/uinteger/zuinteger_unlimited commands to accept literal "unlimited". It also installs a completer. Presently, we complete on symbols by default, and at <http://sourceware.org/ml/gdb-patches/2013-03/msg00864.html> I've shown a WIP prototype that tried to keep that half working in these commands. In the end, it turned out to be more complicated than justifiable, IMO. It's super rare to want to pass the value of a variable/symbol in the program to a GDB set/show knob. That'll still work, it's just that we won't assist with completion anymore. This patch just sticks with the simple, and completes on "unlimited", and nothing else. This simplification means that "set he<tab><tab>" is all it takes to get to: "set height unlimited" The patch then goes through all integer/uinteger/zuinteger_unlimited commands in the tree, and updates both the online help and the manual to mention that "unlimited" is accepted in addition to 0/-1. In the cases where the command had no online help text at all, this adds it. I've tried to make the texts read in a way that "unlimited" is suggested before "0" or "-1" is.

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. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-script.c (read_next_line): Adjust to per-UI stdin.

Add new command to create extra console/mi UIs With all the previous plumbing in place, it's now easy to add a command that actually creates a new console/mi UI. The intended use case is to make it possible and easy for MI frontends to provide a fully featured GDB console to users, with readline support, command line editing, history, etc., just like if gdb was started on the command line. Currently MI frontends have to try to implement all of that theirselves and make use of "-interpreter-exec console ...", which is far from perfect. If you ever tried Eclipse's gdb console window, you'll know what I mean... Instead of trying to multiplex console through MI, this command let's just leverage all the built in readline/editing support already inside gdb. The plan is for the MI frontend to start GDB in regular console mode, running inside a terminal emulator widget embedded in Eclipse (which already exists, for supporting the shell widget; other frontends have similar widgets), and then tell GDB to run a full MI interpreter on an specified input/output device, independent of the console. My original prototype planned to do things the other way around -- start GDB in MI mode, and then start an extra CLI console on separate tty. I handed over that prototype to Marc Khouzam @ Eclipse CDT, and after experimentation and discussion, we ended up concluding that starting GDB in CLI mode instead was both easier and actually also supported an interesting use case -- connect an Eclipse frontend to a GDB that is already running outside Eclipse. The current usage is "new-ui <interpreter> <tty>". E.g., on a terminal run this scriplet: $ cat gdb-client #!/bin/bash reset tty tail -f /dev/null $ gdb-client /dev/pts/15 Now run gdb on another terminal, and tell it to start a MI interpreter on the tty of the other terminal: ... (gdb) new-ui mi /dev/pts/15 New UI allocated Now back to the the gdb-client terminal, we'll get an MI prompt, ready for MI input: /dev/pts/15 =thread-group-added,id="i1" (gdb) You can also start a new UI running a CLI, with: (gdb) new-ui console /dev/pts/15 Though note that this console won't support readline command editing. It works as if "set editing off" was entered. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * interps.c (set_top_level_interpreter): New function, factored out from captured_main.

Don't propagate our current terminal state to the inferior Currently when we start an inferior we have the inferior inherit our terminal state. Under TUI, our terminal is highly modified by ncurses and readline. So when starting an inferior under TUI, the inferior will have a highly modified terminal state which will interfere with standard I/O. For example, $ gdb gdb (gdb) break main (gdb) run (gdb) print puts ("a\nb") a b $1 = 4 (gdb) [enter TUI mode] (gdb) run (gdb) [exit TUI mode] (gdb) print puts ("a\nb") a b $2 = 4 (gdb) print puts ("a\r\nb\r") a b $3 = 6 As you can see, when we start the inferior under the regular interface, puts() prints the text properly. But when we start the inferior under TUI, puts() does not print the text properly. This is because when we start the inferior under TUI it inherits our current terminal state which has been modified by ncurses to, among other things, require an explicit \r\n to print a new line. As a result the inferior performs standard I/O in an unexpected way. Because of this discrepancy, it doesn't seem like a good idea to have the inferior inherit our _current_ terminal state for it may have been modified by readline and/or ncurses. Instead, we should have the inferior inherit a pristine snapshot of our terminal state taken before readline or ncurses have had a chance to alter it. This enables the inferior to run in a more accurate way, more closely mimicking the program's behavior had it run standalone. And it fixes the above mentioned issue. Tested on x86_64-unknown-linux-gnu. gdb/ChangeLog: * terminal.h (set_initial_gdb_ttystate): Declare. * inflow.c (initial_gdb_ttystate): New static variable. (set_initial_gdb_ttystate): New setter.
