2019-09-20Move "fullname" to tui_source_windowTom Tromey1-4/+3
The "fullname" field in tui_source_window_base is only used by one subclass. This patch moves the field to that subclass, and changes it to be a unique_xmalloc_ptr. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <~tui_source_window_base>: Don't declare. <fullname>: Remove. * tui/tui-winsource.c (~tui_source_window_base): Remove. * tui/tui-source.h (struct tui_source_window) <fullname>: New member. * tui/tui-source.c (tui_source_window::set_contents): Update.

2019-09-20Change tui_source_element::line to be a unique_xmalloc_ptrTom Tromey1-3/+1
This changes tui_source_element::line to be a unique_xmalloc_ptr, removing some manual memory management. gdb/ChangeLog 2019-09-20 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (~tui_source_element): Remove.

2019-08-20Change tui_make_window to be a methodTom Tromey1-2/+1
I combined several small changes into one patch here. I believe I started by noticing that the "title" is not needed by tui_gen_win_info and could be self-managing (i.e. std::string). Moving this revealed that "can_box" is also a property of tui_win_info and not tui_gen_win_info; and this in turn caused the changes to tui_make_window and box_win. 2019-08-20 Tom Tromey <tom@tromey.com> * tui/tui-wingeneral.h (tui_make_window): Don't declare. * tui/tui-wingeneral.c (box_win): Change type of win_info.

2019-08-16Remove the TUI execution info windowTom Tromey1-1/+1
The TUI execution info window is unusual in that it is always linked to a source or disassembly window. Even updates of its content are handled by the source window, so it really has no life of its own. This patch removes this window entirely and puts its functionality directly into the source window. This simplifies the code somewhat. This is a user-visible change, because now the box around the source (or disassembly) window encloses the execution info as well. I consider this an improvement as well, though. Note that this patch caused ncurses to start emitting the "CSI Z" sequence, so I've added this to the test suite terminal implementation. gdb/ChangeLog 2019-08-16 Tom Tromey <tom@tromey.com> * tui/tui.h (enum tui_win_type) <EXEC_INFO_WIN>: Remove. * tui/tui-winsource.h (struct tui_exec_info_window): Remove.

2019-08-16Change tui_show_symtab_source to be a methodTom Tromey1-5/+5
This changes tui_show_symtab_source to be a method on tui_source_window. gdb/ChangeLog 2019-08-16 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_update_source_windows_with_addr) (tui_update_source_windows_with_line): Update. * tui/tui-source.h (struct tui_source_window) <show_symtab_source>: Declare.

2019-08-16Introduce tui_source_window_base::set_contents methodTom Tromey1-18/+20
This introduces the tui_source_window_base::set_contents method and implements it in the subclasses. This removes a check of the window type. gdb/ChangeLog 2019-08-16 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <set_contents>: Declare. * tui/tui-winsource.c (tui_source_window_base::update_source_window_as_is): Update. * tui/tui-source.h (struct tui_source_window) <set_contents>: Declare.

2019-08-16Remove "noerror" parameter from some TUI functionsTom Tromey1-17/+5
A few TUI functions take a "noerror" parameter. This is only checked in one spot: in tui_set_source_content, if noerror is false, and if an error occurs, then the function will call print_sys_errmsg. This seems misguided to me, so this patch removes that code and this parameter. gdb/ChangeLog 2019-08-16 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (tui_update_source_window) (tui_update_source_window_as_is): Remove "noerror" parameter. * tui/tui-winsource.c (tui_update_source_window) (tui_update_source_window_as_is): Remove "noerror" parameter.

2019-08-16Remove separate visibility flagTom Tromey1-1/+1
TUI windows keep track of their visibility in a boolean field. However, this is not needed, because a window is visible if and only if it has an underlying curses handle. So, we can remove this separate field. gdb/ChangeLog 2019-08-16 Tom Tromey <tom@tromey.com> * tui/tui.c (tui_is_window_visible): Update. * tui/tui-wingeneral.c (tui_make_window) (tui_gen_win_info::make_visible, tui_refresh_all): Update. * tui/tui-win.c (window_name_completer, tui_refresh_all_win) (tui_set_focus_command, tui_all_windows_info, update_tab_width) (tui_set_win_height_command, parse_scrolling_args): Update. * tui/tui-source.c (tui_source_window::style_changed): Update. * tui/tui-regs.c (tui_show_registers) (tui_data_window::first_data_item_displayed) (tui_data_window::delete_data_content_windows) (tui_check_register_values, tui_reg_command): Update. * tui/tui-disasm.c (tui_show_disassem): Update. * tui/tui-data.h (struct tui_gen_win_info) <is_visible>: New method. <is_visible>: Remove field. * tui/tui-data.c (tui_next_win, tui_prev_win) (tui_delete_invisible_windows): Update.
2019-08-15Remove tui_alloc_source_bufferTom Tromey1-1/+0
There is no longer any need for tui_alloc_source_buffer. The two callers of this function immediately change the contents of the window, undoing the work done by this function. This required adding a move constructor to tui_source_element -- a mildly surprising find, but without this, resizing the vector will cause crashes. This issue was masked earlier because tui_alloc_source_buffer handled this. Note that a patch for this bug was submitted here: https://sourceware.org/ml/gdb-patches/2019-08/msg00094.html That patch is better, IMO, but the author as yet hasn't responded to a request for a ChangeLog entry. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (tui_alloc_source_buffer): Don't declare.

2019-08-15Change tui_line_is_displayed to be a methodTom Tromey1-1/+20
This changes tui_line_is_displayed to be a method on tui_source_window, now that it is obvious that it can only be called for this type. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (tui_line_is_displayed): Don't declare. * tui/tui-winsource.c (tui_line_is_displayed): Move to tui-source.c. * tui/tui-source.h (struct tui_source_window) <line_is_displayed>: Declare. * tui/tui-source.c (tui_source_window::line_is_displayed): New method. (tui_source_window::maybe_update): Update.
2019-08-15Move contents of tui_show_frame_info to new methodTom Tromey1-0/+26
This moves much of the body of tui_show_frame_info to a new method on tui_source_window_base. This removes a check for the type of a window. gdb/ChangeLog 2019-08-15 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_source_window_base) <maybe_update>: Declare. * tui/tui-stack.c (tui_show_frame_info): Call maybe_update method. * tui/tui-source.h (struct tui_source_window) <maybe_update>: Declare. * tui/tui-source.c (tui_source_window::maybe_update): New method. * tui/tui-disasm.h (struct tui_disasm_window) <maybe_update>: Declare. * tui/tui-disasm.c (tui_disasm_window::maybe_update): New method.
2019-08-06Add file offsets to the source cacheTom Tromey1-1/+3
Currently, gdb stores the number of lines and an array of file offsets for the start of each line in struct symtab. This patch moves this information to the source cache. This has two benefits. First, it allows gdb to read a source file less frequently. Currently, a source file may be read multiple times: once when computing the file offsets, once when highlighting, and then pieces may be read again while printing source lines. With this change, the file is read once for its source text and file offsets; and then perhaps read again if it is evicted from the cache. Second, if multiple symtabs cover the same source file, then this will share the file offsets between them. I'm not sure whether this happens in practice. gdb/ChangeLog 2019-08-06 Tom Tromey <tromey@adacore.com> * annotate.c (annotate_source_line): Use g_source_cache. * source-cache.c (source_cache::get_plain_source_lines): Change parameters.

2019-07-17Move source window common to code to tui-winsource.[ch]Tom Tromey1-9/+0
Like the previous rearranging patches, this moves the source and disassembly window base class code to tui-winsource.[ch]. The execution info window is also moved, because it is associated with this base class. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-winsource.h (struct tui_exec_info_window) (struct tui_source_window_base): Move from tui-data.h. * tui/tui-winsource.c: Move many method definitions from elsewhere.

(struct tui_source_window_base): Likewise. * tui/tui-data.c (tui_source_window_base::clear_detail) (tui_source_window_base, ~tui_source_window_base): Move to tui-winsource.c.
2019-07-17Remove the win_type parameter from tui_gen_win_info::resetTom Tromey1-4/+3
tui_gen_win_info::reset has a window type parameter that is only used for an assertion. This made sense as a defensive measure when window creation was more dynamic -- it ensured that one did not make mistakes. However, there's no need for it any more, so this removes it. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-source.c (tui_source_window_base::reset): Remove win_type parameter. * tui/tui-layout.c (make_command_window, make_source_window) (make_disasm_window, make_data_window) (show_source_disasm_command, show_data, tui_gen_win_info::reset) (reset_locator, show_source_or_disasm_and_command): Update. * tui/tui-data.h (struct tui_gen_win_info) <reset>: Remove win_type parameter. (struct tui_source_window_base) <reset>: Likewise.
2019-07-17Always create an execution info window for a source windowTom Tromey1-0/+10
A source or disassembly window will always have an "execution info" window (the window along the side that displays breakpoint info), but this isn't immediately clear from the source. As a result, some code has checks to see whether the execution_info is NULL. This changes the source window base class to always instantiate an execution_info window, then updates the rest of the code. It also simplifies window creation in tui-layout.c. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_set_exec_info_content): Remove condition. * tui/tui-wingeneral.c (tui_source_window_base::make_visible): Remove condition. * tui/tui-source.c (tui_source_window_base::reset): New method. * tui/tui-layout.c (make_command_window): Don't call init_and_make_win.

(show_source_disasm_command, show_data): Simplify. (make_source_or_disasm_window): Remove. (show_source_or_disasm_and_command): Simplify. * tui/tui-data.h (struct tui_gen_win_info) <reset>: Now virtual. (struct tui_source_window_base) <reset>: Likewise. <execution_info>: Remove initializer. * tui/tui-data.c (tui_source_window_base): Initialize execution_info.
2019-07-17Remove tui_source_window::content_in_useTom Tromey1-1/+1
Now that source window clearing has been simplified, we don't need a special flag to say whether the source window is in use -- we can simply check whether the contents are set. This patch implements this idea, removing the content_in_use field. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_clear_source_content) (tui_show_source_content): Update. * tui/tui-source.c (tui_source_window::showing_source_p): Check whether content is empty. * tui/tui-data.h (struct tui_source_window_base) <content_in_use>: Remove.
2019-07-17Simplify source window clearingTom Tromey1-63/+0
When a TUI source window is empty, it displays a "No Source Available" message. The function tui_set_source_content_nil also made sure to put this message into the window's "content" field. However, I believe this isn't really necessary. Instead, it's simpler to just empty the contents and let curses handle the refreshing. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_erase_source_content): Clear the window's contents. * tui/tui-source.h (tui_set_source_content_nil): Don't declare. * tui/tui-source.c (tui_set_source_content_nil): Remove.
2019-07-17Move content_in_use to tui_source_window classTom Tromey1-4/+3
From scanning the source now, it's clear that the content_in_use field is only used for the source window. This patch moves the field there, and changes it to be a bool at the same time. (A future patch will clean this up further, removing the field entirely.) gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_clear_source_content) (tui_show_source_content, tui_show_exec_info_content) (tui_clear_exec_info_content): Update. * tui/tui-stack.c (tui_show_locator_content): Update.

This introduces the location_matches_p method, removing a spot that explicitly examines a window's type. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-winsource.c (tui_update_breakpoint_info): Use location_matches_p. * tui/tui-source.c (tui_source_window::location_matches_p): New method. * tui/tui-disasm.c (tui_disasm_window::location_matches_p): New method. * tui/tui-data.h (struct tui_source_window_base) <location_matches_p>: New method.

2019-07-17Make source windows be self-updatingTom Tromey1-0/+20
This changes the TUI source window to register itself on the source_styling_changed observable, and removes a bit of code from tui-hooks.c. This reduces the number of uses of the TUI_SRC_WIN global. gdb/ChangeLog 2019-07-17 Tom Tromey <tom@tromey.com> * tui/tui-source.c (tui_source_window): New constructor. Add observer.

2019-07-17Remove some uses of TUI_WIN_SRCTom Tromey1-21/+21

2019-07-04Fix TUI use of "has_break" fieldTom Tromey1-1/+1
The TUI uses the "has_break" in two different ways: sometimes as a boolean, and sometimes as flags. This patch changes the TUI to be more type-safe here, and fixes the code. I could not find a bug that this caused, so apparently this is just cosmetic. This deletes some code from tui_set_disassem_content. Whenver this is called, I believe the TUI updates the breakpoint information afterward, so this assignment is redundant; which is good because it is also incorrect. gdb/ChangeLog 2019-07-04 Tom Tromey <tom@tromey.com> PR tui/24724: * tui/tui-winsource.c (tui_clear_source_content): Update.

2019-06-25Remove NULL checks before xfreeTom Tromey1-2/+1
A couple of spots in the TUI did a NULL check before an xfree.

2019-06-25Remove union tui_which_elementTom Tromey1-29/+24
This removes union tui_which_element, instead moving the content directly into tui_source_window_base. This allows for the deletion of a fair amount of code.

2019-06-25Remove struct tui_source_infoTom Tromey1-3/+3
The tui_source_info struct is used as a member of the "detail" union in tui_win_info, and this member of the union is only used by source and disassembly windows. This patch removes tui_source_info and moves its members directly to tui_source_window_base. This simplifies the code by removing a layer of references from many places.

2019-03-18Fix scrolling right in the TUIHannes Domani1-10/+20
This commit fixes two issues in scrolling right in the TUI: #1 - Scrolling right with the arrow keys, the first keypress doesn't do anything. The problem is that copy_source_line() checks if (column < first_col), and because of the ++column directly before, it basically starts with 1 instead of 0. #2 - Scrolling right handles TABS and escaped characters as single characters, which just looks weird. The problem is that there's a spot that misses handling TABS. gdb/ChangeLog: 2019-03-18 Hannes Domani <ssbssa@yahoo.de> * tui/tui-source.c (copy_source_line): Fix handling of 'column'. Handle tabs.

2015-09-25Add casts to memory allocation related callsSimon Marchi1-1/+1
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.

2015-04-27TUI: avoid calling strcpy() on identical string objectsPatrick Palka1-1/+3
In tui_set_source_content(), when offset == 0 the source and destination pointers of the call to strcpy() are actually the same. In this case not only is strcpy() unnecessary but it is also UB when the two strings overlap. gdb/ChangeLog: * tui/tui-source.c (tui_set_source_content): Avoid calling strcpy() when offset is 0.
