2020-01-06GDB: Remove trailing spaces in tui-disasm.cShahab Vahedi1-3/+3
A few trailing spaces are removed. gdb/ChangeLog: 2020-01-06 Shahab Vahedi <shahab@synopsys.com> * tui/tui-disasm.c: Remove trailing spaces.
2020-01-05gdb: use tui_set_layout not show_layout to fix window focusAndrew Burgess1-6/+6
When calling tui_add_win_to_layout, use tui_set_layout not show_layout so that window focus is correctly updated. If the focus is not correctly maintained then GDB can be crashed like this: start tui enable layout asm list SOME_FUNCTION At this point GDB will have "popped up" the source window to display SOME_FUNCTION. Previously no window would have focus at this point, and so if the user now does 'focus next' or 'focus prev', then GDB would crash. Calling tui_set_layout ensures that focus is correctly calculated as the source window is "popped up", and this fixes the issue. gdb/ChangeLog: * tui/tui-layout.c (tui_add_win_to_layout): Use tui_set_layout not show_layout. gdb/testsuite/ChangeLog: * gdb.tui/list.exp: Test 'focus next' after 'list main'.

2019-12-27Remove dead code from TUITom Tromey2-58/+0
I found some dead code in the TUI -- some using #if 0, and some commented-out code.

2019-12-27Remove tui_gen_win_info::viewport_heightTom Tromey5-17/+2
tui_gen_win_info::viewport_height is only used in a couple of spots, and is redundant with "height".

2019-12-20Don't call tui_show_source from tui_ui_outTom Tromey3-18/+1
This removes the call to tui_show_source from tui_ui_out. This always seemed like a hack, and now that the TUI is using the proper observers, it seems not to be needed. The rest of the logic remains, unfortunately, because it is needed to suppress some gdb output in the TUI case. We could probably find a nicer way to do this (maybe a ui_out_flag), but I haven't attempted this. This was the last caller of tui_show_source, so this is removed as well. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_show_source): Remove. * tui/tui.h (tui_show_source): Don't declare. * tui/tui-out.c (tui_ui_out::do_field_string): Don't call tui_show_source.

2019-12-20Fix "list" command in the TUITom Tromey1-44/+58
PR tui/18932 notes that "list" no longer works in the TUI. At some point in the past, it switched the TUI source window to show the specified source; but now this source briefly flashes before the TUI reverts to showing the current stack frame's source. This patch fixes this bug by introducing a new observer that notices when the user selected context has changed. Then, the existing before-prompt observer is updated to request the correct update: either one based on the current stack frame, or one based on the user's source symtab_and_line. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> PR tui/18932: * tui/tui-hooks.c (tui_refresh_frame_and_register_information): Rename parameters.

2019-12-20Don't call set_current_source_symtab_and_line from TUITom Tromey1-7/+0
update_source_window_as_is calls set_current_source_symtab_and_line, but I don't think there is any reason it should be doing this. This patch removes the call. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_source_window_base::update_source_window_as_is): Don't call set_current_source_symtab_and_line.

2019-12-20Remove a call to update_exec_infoTom Tromey1-4/+1
tui_show_frame_info calls update_exec_info after calling erase_source_content, but there's no need to do this, as erase_source_content already clears the exec info. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-stack.c (tui_show_frame_info): Don't call update_exec_info.

2019-12-20Display "main" on initial TUI startupTom Tromey1-0/+2
I noticed that even when there's a symbol file, "tui enable" won't show "main" by default. I think it should, and this patch fixes this. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_enable): Call tui_display_main. gdb/testsuite/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * gdb.tui/list.exp: Check for source on initial listing.

2019-12-20Reimplement tui_get_begin_asm_addressTom Tromey1-14/+17
tui_get_begin_asm_address looks for the inferior's "main" to display it. I think this is incorrect in two ways. First, it should probably instead use the user's most recent source context, if one has been set. Second, it uses a hard-coded list of "main" names, but gdb already has a better approach to handling this. This patch fixes both of these problems. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-disasm.c (tui_get_begin_asm_address): Use get_current_source_symtab_and_line, and main_name.

2019-12-20Simplify tui_update_source_windows_with_lineTom Tromey3-31/+10
This changes tui_update_source_windows_with_line to take a symtab_and_line, rather than separate parameters, and then updates the caller. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_show_source): Update. * tui/tui-winsource.h (tui_update_source_windows_with_line): Update. * tui/tui-winsource.c (tui_update_source_windows_with_line): Take a symtab_symbol_info, not a separate symtab and line.

2019-12-20Simplify tui_update_source_windows_with_addrTom Tromey1-13/+4
After the previous changes, tui_update_source_windows_with_addr simply updates each source-like window separately, passing the same data to each. So, it can be simplified by using a loop instead. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_update_source_windows_with_addr): Simplify.

2019-12-20Use symtab_and_line when updating TUI windowsTom Tromey6-81/+64
This changes a few TUI source window methods to take a symtab_and_line rather than separate symtab and tui_line_or_address parameters. A symtab_and_line already incorporates the same information, so this seemed simpler. Also, it helps avoid the problem that the source and disassembly windows need different information -- both forms are present in the SAL. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <set_contents, update_source_window_as_is, update_source_window>: Take a sal, not a separate symtab and tui_line_or_address. * tui/tui-winsource.c (tui_source_window_base::update_source_window) (tui_source_window_base::update_source_window_as_is): Take a sal, not a separate symtab and tui_line_or_address.

2019-12-20Use start_line_or_addr in TUI windowsTom Tromey3-4/+4
A few spots in the TUI source and disassembly windows referred to content[0], where start_line_or_addr is equivalent. This patch makes this substitution. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_source_window_base::refill): Use start_line_or_addr. * tui/tui-source.c (tui_source_window::do_scroll_vertical): Use start_line_or_addr. * tui/tui-disasm.c (tui_disasm_window::do_scroll_vertical): Use start_line_or_addr.

2019-12-20Change tui_source_window_base::set_contents to return boolTom Tromey6-89/+80
This changes tui_source_window_base::set_contents to return bool, rather than tui_status. It also changes one implementation of set_contents to use early returns rather than a variable, which IMO makes it easier to follow. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <set_contents>: Return bool. * tui/tui-winsource.c (tui_source_window_base::update_source_window_as_is): Update. * tui/tui-source.h (struct tui_source_window) <set_contents>: Return bool. * tui/tui-source.c (tui_source_window::set_contents): Return bool.

2019-12-20Remove tui_show_disassemTom Tromey3-19/+9
tui_show_disassem is just a wrapper for the update_source_window method, and it only has a single caller. This removes the function and inlines the logic into that caller. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_update_source_windows_with_addr): Call update_source_window directly. * tui/tui-disasm.h (tui_show_disassem): Don't declare. * tui/tui-disasm.c (tui_show_disassem): Remove.

2019-12-20Remove some unnecessary focus switchesTom Tromey2-12/+0
A couple of lower-level utility functions can change the TUI focus. This seems incorrect to me -- focus switches should only be done either by explicit user request, or ass a side effect of changing the layout. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_source_window_base::update_source_window_as_is): Don't switch focus. * tui/tui-disasm.c (tui_show_disassem): Don't switch focus.

2019-12-20Simplify tui_source_window_base::maybe_update methodTom Tromey6-25/+21
tui_source_window_base::maybe_update takes a symtab_and_line, plus a separate line number and PC. Because a symtab_and_line already holds a line number and a PC, it is possible to remove these extra parameters. gdb/ChangeLog 2019-12-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <maybe_update>: Remove line_no and addr parameters. * tui/tui-stack.c (tui_show_frame_info): Set PC on sal.

The simplest way to trigger it is to run: $ ./gdb --data-directory=data-directory -batch -ex "layout next" The ASan report is: ================================================================= ==2829136==ERROR: AddressSanitizer: new-delete-type-mismatch on 0x608000009a20 in thread T0: object passed to delete has wrong type: size of the allocated type: 88 bytes; size of the deallocated type: 24 bytes. #0 0x7f470fe2507e in operator delete(void*, unsigned long) /build/gcc/src/gcc/libsanitizer/asan/asan_new_delete.cc:177 #1 0x55f88c75700d in std::default_delete<tui_layout_base>::operator()(tui_layout_base*) const /usr/include/c++/9.2.0/bits/unique_ptr.h:81 #2 0x55f88c756328 in std::unique_ptr<tui_layout_base, std::default_delete<tui_layout_base> >::~unique_ptr() /usr/include/c++/9.2.0/bits/unique_ptr.h:284 #3 0x7f470ee536a6 in __run_exit_handlers (/usr/lib/libc.so.6+0x3e6a6) #4 0x7f470ee5385d in __GI_exit (/usr/lib/libc.so.6+0x3e85d) #5 0x55f88c69f2ac in quit_force(int*, int) /home/simark/src/binutils-gdb/gdb/top.c:1766 #6 0x55f88becc29a in captured_main_1 /home/simark/src/binutils-gdb/gdb/main.c:1183 #7 0x55f88becc814 in captured_main /home/simark/src/binutils-gdb/gdb/main.c:1192 #8 0x55f88becc8a9 in gdb_main(captured_main_args*) /home/simark/src/binutils-gdb/gdb/main.c:1217 #9 0x55f88b3159cd in main /home/simark/src/binutils-gdb/gdb/gdb.c:32 #10 0x7f470ee3c152 in __libc_start_main (/usr/lib/libc.so.6+0x27152) #11 0x55f88b31579d in _start (/home/simark/build/binutils-gdb/gdb/gdb+0x11fb79d) 0x608000009a20 is located 0 bytes inside of 88-byte region [0x608000009a20,0x608000009a78) allocated by thread T0 here: #0 0x7f470fe238f8 in operator new(unsigned long) /build/gcc/src/gcc/libsanitizer/asan/asan_new_delete.cc:104 #1 0x55f88c750906 in tui_layout_split::clone() const /home/simark/src/binutils-gdb/gdb/tui/tui-layout.c:515 #2 0x55f88c74e60e in show_layout /home/simark/src/binutils-gdb/gdb/tui/tui-layout.c:90 #3 0x55f88c74e7db in tui_set_layout(tui_layout_type) /home/simark/src/binutils-gdb/gdb/tui/tui-layout.c:116 #4 0x55f88c782f4f in tui_enable() /home/simark/src/binutils-gdb/gdb/tui/tui.c:481 #5 0x55f88c74eeb2 in tui_layout_command /home/simark/src/binutils-gdb/gdb/tui/tui-layout.c:286 #6 0x55f88b6f969b in do_const_cfunc /home/simark/src/binutils-gdb/gdb/cli/cli-decode.c:107 #7 0x55f88b701859 in cmd_func(cmd_list_element*, char const*, int) /home/simark/src/binutils-gdb/gdb/cli/cli-decode.c:1952 #8 0x55f88c69b455 in execute_command(char const*, int) /home/simark/src/binutils-gdb/gdb/top.c:652 #9 0x55f88bec9026 in catch_command_errors /home/simark/src/binutils-gdb/gdb/main.c:400 #10 0x55f88becc1f2 in captured_main_1 /home/simark/src/binutils-gdb/gdb/main.c:1167 #11 0x55f88becc814 in captured_main /home/simark/src/binutils-gdb/gdb/main.c:1192 #12 0x55f88becc8a9 in gdb_main(captured_main_args*) /home/simark/src/binutils-gdb/gdb/main.c:1217 #13 0x55f88b3159cd in main /home/simark/src/binutils-gdb/gdb/gdb.c:32 #14 0x7f470ee3c152 in __libc_start_main (/usr/lib/libc.so.6+0x27152) The problem is that the tui_layout_base is missing a virtual destructor. We allocate a derived object (tui_layout_split), but delete it through a tui_layout_base pointer. Since the tui_layout_base destructor is not virtual, the derived (tui_layout_split) destructor is not called, only the base destructor. That code is not in gdb-9-branch, so I don't think this patch is relevant for the stable branch. Note that this is caught as a diagnostic with clang: In file included from /home/simark/src/binutils-gdb/gdb/tui/tui-layout.c:22: In file included from /home/simark/src/binutils-gdb/gdb/defs.h:28: In file included from /home/simark/src/binutils-gdb/gdb/gdbsupport/common-defs.h:133: In file included from /home/simark/src/binutils-gdb/gdb/gdbsupport/common-exceptions.h:25: In file included from /usr/bin/../lib64/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../include/c++/9.2.0/memory:80: /usr/bin/../lib64/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../include/c++/9.2.0/bits/unique_ptr.h:81:2: error: delete called on 'tui_layout_base' that is abstract but has non-virtual destructor [-Werror,-Wdelete-abstract-non-virtual-dtor] delete __ptr; ^ /usr/bin/../lib64/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../include/c++/9.2.0/bits/unique_ptr.h:284:4: note: in instantiation of member function 'std::default_delete<tui_layout_base>::operator()' requested here get_deleter()(std::move(__ptr)); ^ /home/simark/src/binutils-gdb/gdb/tui/tui-layout.c:54:41: note: in instantiation of member function 'std::unique_ptr<tui_layout_base, std::default_delete<tui_layout_base> >::~unique_ptr' requested here static std::unique_ptr<tui_layout_base> applied_layout; ^ 1 error generated.

2019-12-11Change "winheight" resizing to use new layout codeTom Tromey3-279/+14
The "winheight" command resizes a specified window, resizing the other windows in the layout to adapt. In the current code, this is done by examining each possible layout separately. The new layout code has a more general approach to handling this, and this patch simply removes the old code in favor of a call into the new layout engine. gdb/ChangeLog 2019-12-11 Tom Tromey <tom@tromey.com> * tui/tui-win.c (tui_set_win_height_command): Call tui_adjust_window_height.

2019-12-11Re-apply the current layout when resizingTom Tromey1-104/+2
The TUI has separate code for each possible layout to handle the case where the terminal window is resized. With the new layout code, this can all be replaced with a call to tui_apply_current_layout, which simply re-applies the current layout. This results in some small differences in behavior when resizing, so some tests are updated. gdb/ChangeLog 2019-12-11 Tom Tromey <tom@tromey.com> * tui/tui-win.c (tui_resize_all): Remove code, call tui_apply_current_layout. gdb/testsuite/ChangeLog 2019-12-11 Tom Tromey <tom@tromey.com> * gdb.tui/resize.exp: Update. * gdb.tui/empty.exp (layouts): Update.

2019-12-11First use of tui_layoutTom Tromey2-167/+52
This patch introduces the first use of tui_layout, by changing show_layout to clone and use the appropriate tui_layout. This resulted in one minor layout change, and also in the unintended -- but good -- side effect that the title of each boxed window is now visible. gdb/ChangeLog 2019-12-11 Tom Tromey <tom@tromey.com> * tui/tui-layout.h (tui_apply_current_layout): Declare. * tui/tui-layout.c (standard_layouts, applied_layout): New globals.

2019-12-11Introduce new layout codeTom Tromey2-0/+506
This introduces a new approach to window layout for the TUI. The idea behind this code is that a layout should be specified in a declarative way, and then be applied by generic code that does not need to know the specifics of every possible layout. This patch itself does not change any behavior, because the new layout engine isn't yet connected to anything. That is, this merely introduces the implementation. This generic approach makes the code more maintainable. It also enables some future changes: * New window types are simpler to add; * User-specified layouts are possible; and * Horizontal layouts are more attainable gdb/ChangeLog 2019-12-11 Tom Tromey <tom@tromey.com> * tui/tui-layout.h (class tui_layout_base) (class tui_layout_window, class tui_layout_split): New. * tui/tui-layout.c (tui_get_window_by_name) (tui_layout_window::clone, tui_layout_window::apply) (tui_layout_window::get_sizes, tui_layout_window::add_split) (tui_layout_split::add_window, tui_layout_split::clone) (tui_layout_split::get_sizes) (tui_layout_split::set_weights_from_heights) (tui_layout_split::adjust_size, tui_layout_split::apply): New functions.

2019-12-11Remove struct tui_pointTom Tromey5-30/+25
struct tui_point does not help very much. It is only used for storage, and never passed between functions. I think it makes the code more verbose without any corresponding benefit, so this patch removes it. gdb/ChangeLog 2019-12-11 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.c (tui_gen_win_info::make_window): Update. * tui/tui-win.c (tui_adjust_win_heights, tui_resize_all): Update. * tui/tui-layout.c (tui_gen_win_info::resize): Update. * tui/tui-data.h (struct tui_point): Remove.

2019-12-01Treat inactive TUI specially in "info win"Tom Tromey1-0/+6

2019-12-01Re-highlight windows when needed during TUI startupTom Tromey1-2/+3
I noticed that "tui enable" did not correctly show the source window as having the focus. Debugging showed that the problem was that tui_update_variables was called after the windows were drawn, and its result was being ignored. This changed the code to re-highlight the windows if the value changed. gdb/ChangeLog 2019-12-01 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_enable): Call tui_update_variables earlier.

2019-12-01Allow using less horizontal space in TUI source windowTom Tromey6-11/+67
The source window currently uses a field width of 6 for line numbers, and it further aligns to the next tab stop. This seemed a bit wasteful of horizontal space to me, so I changed that in an earlier patch. However, that change wasn't universally popular.

2019-11-19Fix the "winheight" commandTom Tromey3-27/+22
The "winheight" command is broken. I probably broke it in one of my TUI refactoring patches, though I didn't track down exactly which one. The bug is that the code does: *buf_ptr = '\0'; ... but then never advances buf_ptr past this point, so no window name is seen. This patch refactors the code a bit so that a copy of the argument string is not needed, also fixing the bug. A new test case is included. gdb/ChangeLog 2019-11-19 Tom Tromey <tom@tromey.com> * tui/tui-win.c (tui_partial_win_by_name): Move from tui-data.c. Now static. Change type of "name".
