Hirohito Higashi 3c3050e648 patch 9.2.0377: Using int as bool type in gui_T struct
Problem:  Several gui_T fields are declared as "int" or "char" but are
          used strictly as boolean flags with TRUE/FALSE values.  The
          integer types obscure the boolean intent and are wider than
          needed.
Solution: Change the following gui_T members to bool (stdbool.h) and
          update their assignments from TRUE/FALSE to true/false
          accordingly (Hirohito Higashi)

The following conversions have been done:
- int -> bool (11 members):
  in_focus, in_use, starting, dying, dofork, dospawn,
  pointer_hidden, force_redraw, directx_enabled, font_can_bold,
  which_scrollbars[3]
- char -> bool (2 members):
  cursor_is_valid, menu_is_active

No existing code compares these members against TRUE/FALSE explicitly
(e.g. "== TRUE"), so only plain assignments are affected.

gui_init() used counter-style "--gui.starting" / "++gui.starting" to
temporarily clear the flag across a call to gui_mch_enable_menu().
With gui.starting now bool this triggers -Werror=bool-operation, so
replace it with an explicit save/restore.

X11 Bool members (rsrc_rev_video, color_approx) are intentionally left
unchanged: rsrc_rev_video is registered as an X Toolkit resource with
XtRBool / sizeof(Bool) and must keep the int-sized X11 Bool type.

Gary Johnson dd40b1af5b patch 9.2.0334: GTK: window geometry shrinks with with client-side decorations
Problem:  On GTK3 with client-side decorations the window opens with
          wrong &columns/&lines, and each :tabnew/:tabclose cycle
          shrinks the size further.
Solution: Measure and compensate for the CSD frame offset, discard
          spurious configure events from tabline show/hide
          (Gary Johnson).

Christian Brabandt 48b913d735 patch 9.2.0122: Vim still supports compiling on NeXTSTEP
Problem:  Vim still supports compiling on NeXTSTEP
Solution: Drop Support (Damien Lejay)

The NeXTSTEP operating system has been obsolete for decades. The
special-case code required to support it adds unnecessary complexity,
preprocessor conditionals, and non-standard workarounds to the codebase.

This commit removes all support for NeXTSTEP, simplifying the code and
build system in several ways:

-   Replaced custom configure checks for `union wait` with a standard `AC_CHECK_FUNCS` call for `waitpid`.
-   Removed all conditional code that used the non-standard `union wait` for process status, relying solely on a standard `int`.
-   Replaced calls to the non-standard `wait4()` function with the POSIX-standard `waitpid()`.
-   Cleaned up headers (`os_unix.h`, `os_unixx.h`) to remove NeXT-specific workarounds and macros.
-   Removed obsolete NeXT compilation instructions from the INSTALL file.

This change improves maintainability and makes the Unix process handling code more linear and compliant with modern POSIX standards.

Christoffer Aasted ac9426bf54 patch 9.2.0010: Using Wayland compositor is still slow
Problem:  Using the Wayland backend in GTK, rendering remains slow due
          to per-line redraws, unnecessary Cairo push/pop groups, and
          scroll operations that allocate new surfaces repeatedly.
Solution: Improve rendering performance (Christoffer Aasted).

This commit does the following:
- Add gui.is_wayland to detect Wayland backend
- Avoid blocking the input loop
- Skip early redraws; let the compositor handle full-screen redraws
- Use CAIRO_OPERATOR_SOURCE to overwrite instead of blend
- Reuse scroll source region for destination scroll region
- Optimize fast scroll-up
- Remove cairo_push_group/pop_group and cairo_clip in scroll path
  to reduce allocations (~50MB saved on 4K fractional scale)

Since Wayland redraws the entire screen between updates (unlike X11),
further performance gains are possible by batching drawing in other code
paths, e.g.:
- message.c: batch lines to avoid scroll
- term.c: batch terminal redraws

These could be refactored later to deferred redraw with Wayland.

John Marriott a7e671fbb9 patch 9.1.2044: Inefficient use of ga_concat()
Problem:  Inefficient use of ga_concat()
Solution: Use ga_concat_len() when the length is already known to avoid
          use of strlen() (John Marriott).

Additionally the following changes are done:
os_unix.c:
- in function `socket_server_list_sockets()` use a `string_T` for the
  strings `buf` and `path` for use in `ga_concat_len()`
  and drop un-needed variable `dir`.

quickfix.c:
- in function `qf_jump_print_msg()` use a `string_T` for the string
  `IObuff` for use in `ga_concat_len()`.
- in function `qf_range_text()` use a `string_T` for the string `buf`
  for use in `ga_concat_len()`.

register.c:
- simplify function `execreg_line_continuation()`.

terminal.c:
- in function `read_dump_file()` use a `string_T` for the
  string `prev_char` for use in `ga_concat_len()`.

tuple.c:
- in function `tuple_join_inner()` use a `string_T` for the
  string `s` for use in `ga_concat_len()`. Also, change local struct
  `join_T` to use `string_T`.

vim9type.c:
- in functions `type_name_tuple()` and `type_name_func()`
  use a `string_T` for the string `arg_type` for use in
  `ga_concat_len()`.

          of gvim even when set rop=type:directx is used. Setting
          guiligatures also doesn't make any difference. This leads to
          broken font ligatures when the cursor passes through them. It
          does not recover from this, and they remain broken until you
          re-render the whole buffer (e.g. by using Ctrl+L).

Solution: the problem is that we only re-draw the current and previous
          character in gui_undraw_cursor() and only have the special case
          for GTK when it comes to rendering ligatures. So let's enable
          gui_adjust_undraw_cursor_for_ligatures() to also happen for
          Win32 GUI if guiligatures is setup correctly (all this does is
          expand the range of gui_undraw_cursor() with ligature characters).

Sean Dewar 988f74311c patch 9.1.0047: issues with temp curwin/buf while cmdwin is open
Problem:  Things that temporarily change/restore curwin/buf (e.g:
          win_execute, some autocmds) may break assumptions that
          curwin/buf is the cmdwin when "cmdwin_type != 0", causing
          issues.

Solution: Expose the cmdwin's real win/buf and check that instead. Also
          try to ensure these variables are NULL if "cmdwin_type == 0",
          allowing them to be used directly in most cases without
          checking cmdwin_type. (Sean Dewar)

Alternatively, we could ban win_execute in the cmdwin and audit all places that
temporarily change/restore curwin/buf, but I didn't notice any problems arising
from allowing this (standard cmdwin restrictions still apply, so things that may
actually break the cmdwin are still forbidden).

Keith Thompson 184f71cc68 patch 9.1.0006: is*() and to*() function may be unsafe
Problem:  is*() and to*() function may be unsafe
Solution: Add SAFE_* macros and start using those instead
          (Keith Thompson)

Use SAFE_() macros for is*() and to*() functions

The standard is*() and to*() functions declared in <ctype.h> have
undefined behavior for negative arguments other than EOF.  If plain char
is signed, passing an unchecked value from argv for from user input
to one of these functions has undefined behavior.

Solution: Add SAFE_*() macros that cast the argument to unsigned char.

Most implementations behave sanely for negative arguments, and most
character values in practice are non-negative, but it's still best
to avoid undefined behavior.

The change from #13347 has been omitted, as this has already been
separately fixed in commit ac709e2fc0
(v9.0.2054)
