2017-08-16Add shortcuts for "nexti" and "stepi" commands in Single-Key modeRuslan Kabatsayev1-0/+2
Currently, "layout asm" is not so useful as "layout src" with Single-Key mode: you have to use multi-key commands like "ni" and "si" to do single-stepping. This patch adds, in addition to "next" and "step" commands, corresponding assembly-level ones - "nexti" and "stepi" - to Single-Key mode, with the shortcuts of "o" (from "step Over") and "i" (from "Step Into") respectively. gdb/ChangeLog: * tui/tui.c (tui_commands): Add "nexti" and "stepi" to the Single-Key mode command list. gdb/doc/ChangeLog: * gdb.texinfo (TUI Single Key Mode): Document the new shortcuts in Single-Key mode.
2017-08-03Replace tui_restore_gdbout with scoped_restoreTom Tromey1-20/+6
This patch replaces tui_restore_gdbout (a cleaup function) with a use of scoped_restore. This one is broken out into its own patch because it might slightly change the behavior of gdb: it saves and restores pagination_enabled, whereas the tui_restore_gdbout unconditionally set pagination_enabled to 1; and I think this warrants closer review. ChangeLog 2017-08-03 Tom Tromey <tom@tromey.com> * tui/tui-regs.c (tui_restore_gdbout): Remove. (tui_register_format): Use scoped_restore.
2017-07-17Introduce class completion_tracker & rewrite completion<->readline interactionPedro Alves3-22/+22
This patch reworks the whole completion machinery, and prepares it for later enhancements. Adds a new "completion_tracker" class that is meant to hold everything about the state of the current completion operation. This class now has the responsibility of tracking the list of completion matches, and checking whether the max completions limit has been reached. You can look at this as this patch starting out by C++fying the existing "completion_tracker" in symtab.c (it's just an htab_t typedef currently), moving it to completer.h/c, and then making it a class/generalizing/enhancing it. Unlike with the current tracking, completion_tracker now checks whether the limit has been reached on each completion match list insertion. This both simplifies the max-completions handling code (maybe_add_completion_enum is gone, for example), and is a prerequisite for follow up patches. The current completion_tracker is only used for symbol completions, and the symbol code gets at the current instance via globals. This patch cleans that up by adding a completion_tracker reference to the signature of the completion functions, and passing the tracker around everywhere necessary. Then, the patch changes how the completion match list is handed over to readline. Currently, we're using the rl_completion_entry_function readline entry point, and the patch switches to rl_attempted_completion_function. A following patch will want to let GDB itself decide the common completion prefix between all matches (what readline calls the "lowest common denominator"), instead of having readline compute it, and that's not possible with the rl_completion_entry_function entry point. Also, rl_attempted_completion_function lets GDB hand over the match list to readline as an array in one go instead of passing down matches one by one, so from that angle it's a nicer entry point anyway. Lastly, the patch catches exceptions around the readline entry points, because we can't let C++ exceptions cross readline. We handle that in the readline input entry point, but the completion entry point isn't guarded, so GDB can abort if completion throws. E.g., in current master: (gdb) b -function "fun<tab> terminate called after throwing an instance of 'gdb_exception_RETURN_MASK_ERROR' Aborted (core dumped) This patch fixes that. This will be exercised in the new tests added later on in the series. gdb/ChangeLog: 2017-07-17 Pedro Alves <palves@redhat.com> * ada-lang.c (symbol_completion_match): Adjust comments.

2017-05-19Fix tui compilation with Solaris libcurses: non-const last arg to mvwaddstr ↵Rainer Orth3-5/+6
(PR tui/21482) On both mainline and the 8.0 branch, gdb compilation fails on Solaris 10 with the native libcurses in gdb/tui for several instances of the same problem: /vol/src/gnu/gdb/gdb-8.0-branch/local/gdb/tui/tui-winsource.c: In function `void tui_erase_source_content(tui_win_info*, int)': /vol/src/gnu/gdb/gdb-8.0-branch/local/gdb/tui/tui-winsource.c:257:18: error: invalid conversion from `const char*' to `char*' [-fpermissive] no_src_str); ^ In file included from /vol/src/gnu/gdb/gdb-8.0-branch/local/gdb/gdb_curses.h:42:0, from /vol/src/gnu/gdb/gdb-8.0-branch/local/gdb/tui/tui-data.h:26, from /vol/src/gnu/gdb/gdb-8.0-branch/local/gdb/tui/tui-winsource.c:33: /vol/gcc-7/lib/gcc/sparc-sun-solaris2.10/7.1.0/include-fixed/curses.h:699:12: note: initializing argument 4 of `int mvwaddstr(WINDOW*, int, int, char*)' extern int mvwaddstr(WINDOW *, int, int, char *); ^~~~~~~~~ make[2]: *** [Makefile:1927: tui-winsource.o] Error 1 Unlike ncurses, <curses.h> declares extern int mvwaddstr(WINDOW *, int, int, char *); i.e. the last arg is char *, not const char *. The patch fixes this by casting the last arg to mvwaddstr to char *, as was recently done on mainline in a newterm() call (the only difference between 8.0 and mainline gdb/tui). * tui/tui-windata.c (tui_erase_data_content): Cast last mvwaddstr arg to char *. * tui/tui-wingeneral.c (box_win): Likewise. * tui/tui-winsource.c (tui_erase_source_content): Likewise.

2017-03-08Fix PR tui/21216: TUI line breaks regressionPedro Alves4-40/+91
Commit d7e747318f4d04 ("Eliminate make_cleanup_ui_file_delete / make ui_file a class hierarchy") regressed the TUI's command window. Newlines miss doing a "carriage return", resulting in output like: ~~~~~~~~~~~~~~~~~~ (gdb) helpList of classes of commands: aliases -- Aliases of other commands breakpoints -- Making program stop at certain points ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Before the commit mentioned above, the default ui_file->to_write implementation had a hack that would defer into the ui_file->to_fputs method. The TUI's ui_file did not implement the to_write method, so all writes would end up going to the ncurses window via tui_file_fputs -> tui_puts. After the commit above, the hack is gone, but the TUI's ui_file still does not implement the ui_file::write method. Since tui_file inherits from stdio_file, writing to a tui_file ends up doing fwrite on the FILE stream the TUI is "associated" with, via stdio_file::write, instead of writing to the ncurses window. The fix is to have tui_file override the "write" method.

The "init" method remains in place, but it now returns void. - A few places check if the interpreter method is NULL before calling it, and also check whether the method returns true/false.

2017-02-02Move "tee" building down to interpreter::set_logging_procPedro Alves1-1/+1
This patch gets rid of this hack in mi_set_logging: /* The tee created already is based on gdb_stdout, which for MI is a console and so we end up in an infinite loop of console writing to ui_file writing to console etc. So discard the existing tee (it hasn't been used yet, and MI won't ever use it), and create one based on raw_stdout instead. */ By pushing down responsibility for the tee creation to the interpreter. I.e., pushing the CLI bits out of handle_redirections down to the CLI interpreter's set_logging_proc method.

2017-02-02Eliminate make_cleanup_ui_file_delete / make ui_file a class hierarchyPedro Alves6-263/+61
This patch starts from the desire to eliminate make_cleanup_ui_file_delete, but then goes beyond. It makes ui_file & friends a real C++ class hierarchy, and switches temporary ui_file-like objects to stack-based allocation. - mem_fileopen -> string_file mem_fileopen is replaced with a new string_file class that is treated as a value class created on the stack. This alone eliminates most make_cleanup_ui_file_delete calls, and, simplifies code a whole lot (diffstat shows around 1k loc dropped.) string_file's internal buffer is a std::string, thus the "string" in the name. This simplifies the implementation much, compared to mem_fileopen, which managed growing its internal buffer manually. - ui_file_as_string, ui_file_strdup, ui_file_obsavestring all gone The new string_file class has a string() method that provides direct writable access to the internal std::string buffer. This replaced ui_file_as_string, which forced a copy of the same data the stream had inside. With direct access via a writable reference, we can instead move the string out of the string_stream, avoiding deep string copying. Related, ui_file_xstrdup calls are replaced with xstrdup'ping the stream's string, and ui_file_obsavestring is replaced by obstack_copy0. With all those out of the way, getting rid of the weird ui_file_put mechanism was possible. - New ui_file::printf, ui_file::puts, etc. methods These simplify / clarify client code. I considered splitting client-code changes, like these, e.g.: - stb = mem_fileopen (); - fprintf_unfiltered (stb, "%s%s%s", - _("The valid values are:\n"), - regdesc, - _("The default is \"std\".")); + string_file stb; + stb.printf ("%s%s%s", + _("The valid values are:\n"), + regdesc, + _("The default is \"std\".")); In two steps, with the first step leaving fprintf_unfiltered (etc.) calls in place, and only afterwards do a pass to change all those to call stb.printf etc.. I didn't do that split, because (when I tried), it turned out to be pointless make-work: the first pass would have to touch the fprintf_unfiltered line anyway, to replace "stb" with "&stb". - gdb_fopen replaced with stack-based objects This avoids the need for cleanups or unique_ptr's. I.e., this: struct ui_file *file = gdb_fopen (filename, "w"); if (filename == NULL) perror_with_name (filename); cleanups = make_cleanup_ui_file_delete (file); // use file. do_cleanups (cleanups); is replaced with this: stdio_file file; if (!file.open (filename, "w")) perror_with_name (filename); // use file. - odd contorsions in null_file_write / null_file_fputs around when to call to_fputs / to_write eliminated. - Global null_stream object A few places that were allocating a ui_file in order to print to "nowhere" are adjusted to instead refer to a new 'null_stream' global stream. - TUI's tui_sfileopen eliminated. TUI's ui_file much simplified The TUI's ui_file was serving a dual purpose. It supported being used as string buffer, and supported being backed by a stdio FILE. The string buffer part is gone, replaced by using of string_file. The 'FILE *' support is now much simplified, by making the TUI's ui_file inherit from stdio_file. gdb/ChangeLog: 2017-02-02 Pedro Alves <palves@redhat.com> * ada-lang.c (type_as_string): Use string_file. * ada-valprint.c (ada_print_floating): Use string_file. * ada-varobj.c (ada_varobj_scalar_image) (ada_varobj_get_value_image): Use string_file. * aix-thread.c (aix_thread_extra_thread_info): Use string_file. * arm-tdep.c (_initialize_arm_tdep): Use string_printf. * breakpoint.c (update_inserted_breakpoint_locations) (insert_breakpoint_locations, reattach_breakpoints) (print_breakpoint_location, print_one_detail_ranged_breakpoint) (print_it_watchpoint): Use string_file.

2016-12-22Class-ify ui_outSimon Marchi6-107/+101
This patch finalizes the C++ conversion of the ui-out subsystem, by turning the ui_out and ui_out_impl structures into a single class hierarchy. ui_out functions are turned into virtual methods of that new class, so as a result there are a lot of call sites to update. In the previous version of the patchset, there were separate ui_out and ui_out_impl classes, but it wasn't really useful and added boilerplate. In this version there is simply an ui_out base class that is extended for CLI, TUI and MI. It's a bit hard to maintain a ChangeLog for such a big patch, I did my best but I'm sure there are some missing or outdated info in there... gdb/ChangeLog: * ui-out.h (ui_out_begin, ui_out_end, ui_out_table_header, ui_out_table_body, ui_out_field_int, ui_out_field_fmt_int, ui_out_field_core_addr, ui_out_field_string, ui_out_field_stream, ui_out_field_fmt, ui_out_field_skip, ui_out_spaces, ui_out_text, ui_out_message, ui_out_wrap_hint, ui_out_flush, ui_out_test_flags, ui_out_query_field, ui_out_is_mi_like_p, ui_out_redirect): Remove, replace with a method in class ui_out.

2016-11-09tui-winsource: Allocate for actual lines onlyAndreas Arnez1-2/+5
The logic for allocating a TUI source window's content buffer allocates two more lines than needed, because it does not reduce the window height by the highlight box's overhead. However, it does reduce the line width accordingly. This patch makes the height and width calculation consistent and improves the comment. gdb/ChangeLog: * tui/tui-winsource.c (tui_alloc_source_buffer): Subtract highlight box's overhead when calculating the content height.
2016-11-09tui-disasm: Fix line buffer size calculationAndreas Arnez1-9/+10
The code that fills the TUI disassembly window content first calculates the maximum full length of a displayed disassembly line. This calculation typically yields the wrong result. The result is too large, so the bug does not cause any run-time failures, but unnecessary confusion for the reader. This patch fixes the calculation. gdb/ChangeLog: * tui/tui-disasm.c (tui_set_disassem_content): Fix calculation of the longest disassembly line's length.
2016-11-09tui-disasm: Fix window content buffer overrunAndreas Arnez1-14/+10
A user reported a GDB crash with TUI when trying to debug a function with a long demangled C++ method name. It turned out that the logic for displaying the TUI disassembly window has a bug that can cause a buffer overrun, possibly overwriting GDB-internal data structures. In particular, the logic performs an unguarded strcpy. Another (harmless) bug in tui_alloc_source_buffer causes the buffer to be two lines longer than needed. This may have made the crash appear less frequently. gdb/ChangeLog: * tui/tui-disasm.c (tui_set_disassem_content): Fix line buffer overrun due to unchecked strcpy. gdb/testsuite/ChangeLog: * gdb.base/tui-layout.c: New file. * gdb.base/tui-layout.exp: Use tui-layout.c, to ensure that the disassembly window contains very long lines.

2016-10-03Emit inferior, thread and frame selection events to all UIsAntoine Tremblay1-0/+33
With this patch, when an inferior, thread or frame is explicitly selected by the user, notifications will appear on all CLI and MI UIs. When a GDB console is integrated in a front-end, this allows the front-end to follow a selection made by the user ont he CLI, and it informs the user about selection changes made behind the scenes by the front-end. This patch addresses PR gdb/20487. In order to communicate frame changes to the front-end, this patch adds a new field to the =thread-selected event for the selected frame. The idea is that since inferior/thread/frame can be seen as a composition, it makes sense to send them together in the same event. The vision would be to eventually send the inferior information as well, if we find that it's needed, although the "=thread-selected" event would be ill-named for that job. Front-ends need to handle this new field if they want to follow the frame selection changes that originate from the console. The format of the frame attribute is the same as what is found in the *stopped events. Here's a detailed example for each command and the events they generate: thread ------ 1. CLI command: thread 1.3 MI event: =thread-selected,id="3",frame={...} 2. MI command: -thread-select 3 CLI event: [Switching to thread 1.3 ...] 3. MI command (CLI-in-MI): thread 1.3 MI event/reply: &"thread 1.3\n" ~"#0 child_sub_function () ... =thread-selected,id="3",frame={level="0",...} ^done frame ----- 1. CLI command: frame 1 MI event: =thread-selected,id="3",frame={level="1",...} 2. MI command: -stack-select-frame 1 CLI event: #1 0x00000000004007f0 in child_function... 3. MI command (CLI-in-MI): frame 1 MI event/reply: &"frame 1\n" ~"#1 0x00000000004007f9 in ..." =thread-selected,id="3",frame={level="1"...} ^done inferior -------- Inferior selection events only go from the console to MI, since there's no way to select the inferior in pure MI. 1. CLI command: inferior 2 MI event: =thread-selected,id="3" Note that if the user selects an inferior that is not started or exited, the MI doesn't receive a notification. Since there is no threads to select, the =thread-selected event does not apply... 2. MI command (CLI-in-MI): inferior 2 MI event/reply: &"inferior 2\n" ~"[Switching to inferior 2 ...]" =thread-selected,id="4",frame={level="0"...} ^done Internal implementation detail: this patch makes it possible to suppress notifications caused by a CLI command, like what is done in mi-interp.c. This means that it's now possible to use the add_com_suppress_notification function to register a command with some event suppressed. It is used to implement the select-frame command in this patch. The function command_notifies_uscc_observer was added to extract the rather complicated logical expression from the if statement. It is also now clearer what that logic does: if the command used by the user already notifies the user_selected_context_changed observer, there is not need to notify it again. It therefore protects again emitting the event twice.

2016-06-21Simplify starting the command event loopPedro Alves1-1/+1
All interpreter types (CLI/TUI/MI) print the prompt, and then call start_event_loop. Because we'll need an interpreter hook to display the interpreter-specific prompt before going back to the event loop, without actually starting an event loop, this patch moves the start_event_loop call to common code, and replaces the command_loop hook with a pre_command_look hook, that now just prints the prompt.

2016-06-21Make command line editing (use of readline) be per UIPedro Alves2-3/+8
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! Aborted (core dumped) The fix for that was to add an interp_proc method to query the interpreter whether it actually supports editing.

2016-06-21Make the intepreters output to all UIsPedro Alves1-31/+96
When we have multiple consoles, MI channels, etc., then we need to broadcast breakpoint hits, etc. to all UIs. In the past, I've adjusted most of the run control to communicate events to the interpreters through observer notifications, so events would be properly sent to console and MI streams, in sync and async modes. This patch does the next logical step -- have each interpreter's observers output interpreter-specific info to _all_ UIs. Note that when we have multiple instances of active cli/tui interpreters, then the cli_interp and tui_interp globals no longer work. This is addressed by this patch. Also, the interpreters currently register some observers when resumed and remove them when suspended. If we have multiple instances of the interpreters, and they can be suspended/resumed at different, independent times, that no longer works. What we instead do is always install the observers, and then have the observers themselves know when to do nothing. An earlier prototype of this series did the looping over struct UIs in common code, and then dispatched events to the interpreters through a matching interp_on_foo method for each observer. That turned out a lot more complicated than the present solution, as we'd end up with having to create a new interp method every time some interpreter wanted to listen to some observer notification, resulting in a lot of duplicated make-work and more coupling than desirable. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-interp.c (cli_interp): Delete.

2016-06-21Introduce interpreter factoriesPedro Alves1-13/+25
If every UI instance has its own set of interpreters, then the current scheme of creating the interpreters at GDB initialization time no longer works. We need to create them whenever a new UI instance is created. The scheme implemented here has each interpreter register a factory callback that when called creates a new instance of a specific interpreter type. Then, when some code in gdb looks up an interpreter (always by name), if there's none yet, the factory method is called to construct one. gdb/ChangeLog: 2016-06-21 Pedro Alves <palves@redhat.com> * cli/cli-interp.c (cli_uiout): Delete, moved into ...

As can be seen in the tui_redisplay_readline comment: "The command could call prompt_for_continue and we must not restore SingleKey so that the prompt and normal keymap are used." immediate_quit is being used as proxy for "secondary prompt".

2015-10-26tui: Simplify tui_alloc_contentSimon Marchi1-25/+14
I stumbled upon this while doing some cxx-conversion work. Since the x-family alloc functions throw on failure, it is useless to test their result for failure. The else branch of != NULL is basically dead code. I changed the type of element_block_ptr to struct tui_win_element, which seems obvious (this is actually what raised the flag, casting the result of xmalloc to struct tui_win_element* wouldn't work). gdb/ChangeLog: * tui/tui-data.c (tui_alloc_content): Don't check xmalloc result. Change type of element_block_ptr. Change allocation to use XNEWVEC.

2015-09-25Add casts to memory allocation related callsSimon Marchi3-5/+6
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. I fixed some bits by hand, but there might be some wrong parts left (hopefully not). gdb/ChangeLog: * aarch64-linux-tdep.c (aarch64_stap_parse_special_token): Add cast to allocation result assignment. * ada-exp.y (write_object_renaming): Likewise.

2015-09-09Replace "struct continuation" mechanism by something more extensiblePedro Alves1-0/+13
This adds an object oriented replacement for the "struct continuation" mechanism, and converts the stepping commands (step, next, stepi, nexti) and the "finish" commands to use it. It adds a new thread "class" (struct thread_fsm) that contains the necessary info and callbacks to manage the state machine of a thread's execution command. This allows getting rid of some hacks. E.g., in fetch_inferior_event and normal_stop we no longer need to know whether a thread is doing a multi-step (e.g., step N). This effectively makes the intermediate_continuations unused -- they'll be garbage collected in a separate patch. (They were never a proper abstraction, IMO. See how fetch_inferior_event needs to check step_multi before knowing whether to call INF_EXEC_CONTINUE or INF_EXEC_COMPLETE.) The target async vs !async uiout hacks in mi_on_normal_stop go away too. print_stop_event is no longer called from normal_stop. Instead it is now called from within each interpreter's normal_stop observer. This clears the path to make each interpreter print a stop event the way it sees fit. Currently we have some hacks in common code to differenciate CLI vs TUI vs MI around this area. The "finish" command's FSM class stores the return value plus that value's position in the value history, so that those can be printed to both MI and CLI's streams. This fixes the CLI "finish" command when run from MI -- it now also includes the function's return value in the CLI stream: (gdb) ~"callee3 (strarg=0x400730 \"A string argument.\") at src/gdb/testsuite/gdb.mi/basics.c:35\n" ~"35\t}\n" +~"Value returned is $1 = 0\n" *stopped,reason="function-finished",frame=...,gdb-result-var="$1",return-value="0",thread-id="1",stopped-threads="all",core="0" -FAIL: gdb.mi/mi-cli.exp: CLI finish: check CLI output +PASS: gdb.mi/mi-cli.exp: CLI finish: check CLI output gdb/ChangeLog: 2015-09-09 Pedro Alves <palves@redhat.com> * Makefile.in (COMMON_OBS): Add thread-fsm.o. * breakpoint.c (handle_jit_event): Print debug output.

2015-09-04gdb/tui: Remove casts of NULL during assignment.Andrew Burgess6-24/+24
In the following code: struct symbol *wsym = (struct symbol *) NULL; the cast of NULL is redundant, it adds noise, and is just one more thing to change if the type of wsym ever changes. There are a relatively small number of places in gdb where the above code pattern is used. Usually the cast is removed like this: struct symbol *wsym = NULL; This commit updates all the places within the gdb/tui directory where we cast NULL during assignment, removing the cast. gdb/ChangeLog: * tui/tui-data.c (win_with_focus): Remove cast of NULL pointer.

2015-08-26Replace some xmalloc-family functions with XNEW-family onesSimon Marchi2-10/+8
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.

2015-08-21tui: don't overwrite a secondary prompt that was given no inputPatrick Palka1-1/+1
This patch fixes the following bug in TUI: (gdb) break foo No symbol table is loaded. Use the "file" command. Make breakpoint pending on future shared library load? (y or [n]) <ENTER> By submitting an empty command line to a secondary prompt, the line corresponding to the secondary prompt is undesirably cleared and overwritten. Outside of a secondary prompt, clearing the prompt line after submitting an empty command line is intended behavior which complements GDB's repeat-command shorthand. But inside a secondary prompt, this behavior is undesired since the shorthand is not applicable in that case. We should retain the secondary-prompt line even when it's given no input. This patch makes sure that a prompt that was given an empty command line is cleared and overwritten only if it's not a secondary prompt. To acheive this, a new predicate is defined which informs us whether the current input handler is a secondary prompt. gdb/ChangeLog: * top.h (gdb_in_secondary_prompt_p): Declare. * top.c (gdb_secondary_prompt_depth): Define. (gdb_in_secondary_prompt_p): Define. (gdb_readline_wrapper_cleanup): Decrement gdb_secondary_prompt_depth. (gdb_readline_wrapper): Increment gdb_secondary_prompt_depth. * tui/tui-io.c (tui_getc): Don't clear the prompt line if we are in a secondary prompt.
2015-08-21Use tui_putc to output newline entered by the userPatrick Palka1-1/+1
This is necessary to make sure that start_line is updated after a command has been entered. Usually, start_line gets updated anyway because most commands output text, and outputting text is done through the function tui_puts, which updates start_line. However if a command does not output text, then tui_puts will not get called and start_line will not get updated in time for the next prompt to be displayed. One can observe this bug by executing the command "delete" within TUI. After executing, the prompt line (gdb) delete gets overwritten by the next prompt. With this patch, the prompt line gets preserved. gdb/ChangeLog: * tui/tui-io.c (tui_getc): Use tui_putc instead of waddch to emit the newline.
2015-08-20Remove fields curch and cur_line from TUI_CMD_WINPatrick Palka4-37/+12
These fields are currently used to track the location of the cursor inside the command window. But their usefulness is questionable because ncurses already internally keeps track of the location of the cursor, whose coordinates we can query using the functions getyx(), getcurx() or getcury(). It is an unnecessary pain to keep these fields in sync with ncurses, and their meaning is not well-defined anyway. For instance, it is not clear whether the coordinates held in these fields are authoritative, or whether the coordinates reported by ncurses are. So to keep things simple, this patch removes these fields and replaces existing reads of these fields with calls to the appropriate ncurses querying functions, and replaces writes to these fields with calls to wmove() (when necessary and applicable). In the function tui_cont_sig(), I removed the call to wmove() entirely because moving to (start_line, curch) makes no sense. The move should have been to (cur_line, curch) -- which would now be a no-op. Tested on x86_64 Fedora 22, no obvious regressions. gdb/ChangeLog: * tui/tui-data.h (tui_command_info): Remove fields cur_line and curch. * tui/tui-data.c (tui_clear_win_detail) [CMD_WIN]: Don't set cur_line or curch, instead call wmove(). (init_win_info) [CMD_WIN]: Likewise. * tui/tui-io.c (tui_puts): Likewise. Don't read cur_line, instead call getcury(). (tui_redisplay_readline): Don't set cur_line or curch. (tui_mld_erase_entire_line): Don't read cur_line, instead call getcury(). (tui_cont_sig): Remove call to wmove. (tui_getc): Don't read cur_line or curch, instead call getcury() or getyx(). Don't set curch. * tui/tui-win.c (make_visible_with_new_height) [CMD_WIN]: Don't set cur_line or curch. Always move cursor to (0,0).
2015-07-13gdb/tui: Add command completion to winheight command.Andrew Burgess1-12/+44
Share the window name completion code from the focus command with the winheight command, providing window name completion for the winheight command. gdb/ChangeLog: * tui/tui-win.c (window_name_completer): New function. (focus_completer): Call window_name_completer. All old content moved into window_name_completer. (winheight_completer): New function. (_initialize_tui_win): Rename variable. Add completer to winheight command. Update doc string on winheight.
2015-07-10gdb/tui: Use cleanups to free string copies.Andrew Burgess1-3/+6
In parse_scrolling_args it is possible for a string copy to leak if an error occurs. Switching to using a cleanup fixes this leak. In tui_set_win_height the string can't be leaked, but switching to using a cleanup guards against the possibility that a leak could be introduced in the future (by adding an error somewhere in the call stack). gdb/ChangeLog: * tui/tui-win.c (tui_set_win_height): Use a cleanup to free the string copy. (parse_scrolling_args): Likewise.
2015-07-10gdb/tui: Define tui window names once.Andrew Burgess1-22/+5
Don't duplicate the window names inside the completion function. Instead make use of the existing defines, and the tui_win_name function to obtain the window names. gdb/ChangeLog: * tui/tui-win.c (focus_completer): Don't duplicate the tui window names in this function.
2015-07-10gdb: Convert TUI windows names to lower case.Andrew Burgess2-9/+9
This commit converts the window names for the TUI windows to lower case. The windows names are already lower case in the documentation, and are shown as lower case in some of the command completion results. Given that all the commands that take a window name currently accept upper or lower case, this commit just changes the window names to lower case in the remaining places they are displayed by gdb. gdb/ChangeLog: * tui/tui-data.h (SRC_NAME): Convert to lower case. (CMD_NAME): Likewise. (DATA_NAME): Likewise. (DISASSEM_NAME): Likewise. * tui/tui-win.c (tui_set_focus): Window names are now lower case. (tui_set_win_height): Likewise. (parse_scrolling_args): Likewise.
2015-07-08tui: replace deprecated_register_changed_hook with observerPatrick Palka1-5/+13
This is a straightforward replacement of the TUI's use of the aforementioned hook with the register_changed observer. Since this was the only user of the hook, this patch also removes the hook. gdb/ChangeLog: * defs.h (deprecated_register_changed_hook): Remove prototype. * interps.c (clear_iterpreter_hooks): Remove reference to deprecated_register_changed_hook. * top.c (deprecated_register_changed_hook): Remove prototype. * valops.c (value_assign): Remove reference to deprecated_register_changed_hook. * tui/tui-hooks.c (tui_register_changed): Add parameter "frame". Add comment documenting the function. (tui_register_changed_observer): Define. (tui_install_hooks): Remove reference to deprecated_register_changed_hook. Set tui_register_changed_observer. (tui_remove_hooks): Remove reference to deprecated_register_changed_hook. Unset tui_register_changed_observer.
