      Replace XChar2b with unsigned in all font backends · a4fe9c70
      Alexander Gramiak authored
      The xfont backend using XChar2b in its API doesn't mean that we should
      use it everywhere else.

      Avoid allocating a Lisp_Save_Value in ftfont.c · 888bf987
      Paul Eggert authored
      * src/ftfont.c (struct ftfont_cache_data): New member face_refcount.
      (ftfont_lookup_cache): Clear it when initializing.
      Use make_mint_ptr, since this typically avoids the need to
      allocate a Lisp_Save_Value as refcount is now stored elsewhere.
      (ftfont_open2, ftfont_close): Manipulate the reference
      count in the struct, not in the save object.

      Prefer HTTPS to FTP and HTTP in documentation · bc511a64
      Paul Eggert authored
      Most of this change is to boilerplate commentary such as license URLs.
      This change was prompted by ftp://ftp.gnu.org's going-away party,
      planned for November.  Change these FTP URLs to https://ftp.gnu.org
      instead.  Make similar changes for URLs to other organizations moving
      away from FTP.  Also, change HTTP to HTTPS for URLs to gnu.org and
      fsf.org when this works, as this will further help defend against
      man-in-the-middle attacks (for this part I omitted the MS-DOS and
      MS-Windows sources and the test tarballs to keep the workload down).
      HTTPS is not fully working to lists.gnu.org so I left those URLs alone
      for now.

      Make struct font_drivers read-only · ebb96114
      Paul Eggert authored
      This simplifies the code a bit, and makes the structs more
      shareable and less likely to become corrupt.

      (register_font_driver, font_update_drivers):

      struct font_drivers are now const.

      Omit no-longer-necessary decls.

      * src/ftxfont.c (syms_of_ftxfont):

      * src/nsfont.m (nsfont_driver):
      * src/xfont.c (xfont_driver):

      Use C99-style initializer for ease of maintenance, and make it const.
      * src/ftcrfont.c, src/ftxfont.c, src/xftfont.c:
      Refer to functions like ftfont_text_extents directly.

      them directly.
      * src/macfont.m (macfont_descriptor_entity):
      * src/nsfont.m (nsfont_open):
      Use constant directly; this is clearer.

      New C macro AUTO_STRING_WITH_LEN · 17cb263a
      Paul Eggert authored
      Put a bit less pressure on the garbage collector by defining a
      macro that is like AUTO_STRING but also allows null bytes in strings,
      and by extending AUTO_STRING to work with any unibyte string.
      * src/alloc.c (verify_ascii): Remove; all uses removed.
      AUTO_STRING can now be used on non-ASCII unibyte strings.
      * src/lisp.h (AUTO_STRING): Now allows non-ASCII unibyte strings.
      (AUTO_STRING_WITH_LEN): New macro.
      * src/coding.c (from_unicode_buffer):
      * src/editfns.c (format_time_string):
      * src/emacs-module.c (module_make_string, module_format_fun_env):

      * src/fns.c (Flocale_info):
      * src/sysdep.c (system_process_attributes):
      Use AUTO_STRING if possible.  This is doable more often now
      that AUTO_STRING works on any unibyte string.

      Rework C source files to avoid ^( · 7352c6c6
      Paul Eggert authored
      Work around Bug#22884 by rewording comments and strings to avoid ‘(’
      at the start of a line unless it starts a function.  This change
      is a short-term hack; in the longer run we plan to fix cc-mode’s
      performance for C files that have ‘(’ at the start of a line in a
      comment or string.
