      Fix the MSDOS build when running under CWSDPMI · 70ec3928
      Eli Zaretskii authored
      * src/msdos.c (the_only_tty_output): Define.
      * src/msdos.h (the_only_tty_output): Declare.
      * src/frame.c (make_terminal_frame) [MSDOS]:
      * src/dispnew.c (init_display) [MSDOS]: Set up
      f->output_data.tty pointer using the_only_tty_output, before
      dereferencing the pointer.  This prevents crashes with DPMI
      servers that provide NULL pointer protection.

      Fix starting temacs interactively · db3b3b35
      Eli Zaretskii authored
      * src/dispnew.c (init_display_interactive): Don't call
      init_faces_initial if we aren't initialized, since
      tty-set-up-initial-frame-faces is not available then.  This
      restores the ability to start "temacs -nw" and also avoids
      bad crashes in "emacs -nw" if the pdumper file is not found.

      DEFVAR_INT variables are now intmax_t · e828765d
      Paul Eggert authored
      Formerly they were fixnums, which led to problems when dealing
      with values that might not fit on 32-bit platforms, such as
      string-chars-consed or floats_consed.  64-bit counters should
      be good enough for these (for a while, anyway...).
      While we’re at it, fix some unlikely integer overflow bugs

      Rename Emacs-specific INFINITY constants · 222b5970
      Paul Eggert authored
      Although these constants were not erroneous, as they were

      Improve bignum support for system types · d77d01d2
      Paul Eggert authored
      Use bignums when Emacs converts to and from system types like
      off_t for file sizes whose values can exceed fixnum range.
      Formerly, Emacs sometimes generted floats and sometimes ad-hoc
      conses of integers.  Emacs still accepts floats and conses for
      these system types, in case some stray Lisp code is generating
      them, though this usage is obsolescent.

      * src/xdisp.c (move_it_in_display_line_to): Don't exit the loop
      under truncate-lines if the glyph at TO_CHARPOS was not yet
      produced.  This avoids bailing out too early when we are at
      TO_CHARPOS, but didn't yet produce glyphs for that buffer
      position, because the last call to PRODUCE_GLYPHS at this position
      was for an object other than the buffer.  For further details, see

      Narrow pointer bounds when appropriate · 4295050e

      This typically occurs in a storage manager, where the caller

      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.

      Limit <config.h>’s includes · f4eb8900
      Paul Eggert authored
      This follows up on recent problems with the fact that config.h
      includes stdlib.h etc.; some files need to include stdlib.h later.
      config.h generally should limit itself to includes that are
      universally safe; outside of MS-Windows, only stdbool.h makes
      the cut among the files currently included.  So, move the
      other includes to just the files that need them (Bug#24506).
      * configure.ac (config_opsysfile): Remove, as this generic hook
      is no longer needed.
      * lib-src/etags.c, src/unexmacosx.c, src/w32.c, src/w32notify.c:
      * src/w32proc.c (_GNU_SOURCE):
      Remove, as it’s OK for config.h to do this now.
      * src/conf_post.h: Include <ms-w32.h>, instead of the generic
      config_opsysfile, for simplicity as this old way of configuring is
      now done only for the MS-Windows port.  Do not include <ms-w32.h>
      if DEFER_MS_W32_H, for the benefit of the few files that want its
      effects later.  Do not include <alloca.h>, <string.h>, or
      <stdlib.h>.  Other files modified to include these headers as
      needed, or to not include headers that are no longer needed.
      * src/lisp.h: Include <alloca.h> and <string.h> here, since
      some of the inline functions need them.
      * src/regex.c: Include <alloca.h> if not emacs.  (If emacs,
      we can rely on SAFE_ALLOCA.)  There is no longer any need to
      worry about HAVE_ALLOCA_H.
      * src/unexmacosx.c: Rely on config.h not including stdlib.h.
      * src/w32.c, src/w32notify.c, src/w32proc.c (DEFER_MS_W32_H):
      Define before including <config.h> first, and include <ms-w32.h>
      after the troublesome headers.

      Problem reported by Kylie McClain for musl in:
      http://lists.gnu.org/archive/html/emacs-devel/2016-03/msg01592.html

      to make file-descriptor manipulation easier to follow.
      * src/emacs.c (relocate_fd) [!WINDOWSNT]: Remove; no longer needed
      now that we make sure stdin, stdout and stderr are open.  All uses
      removed.
      (main): Make sure standard FDs are OK.  Prefer symbolic names like
      EXIT_FAILURE to magic numbers like 1.  Use bool for boolean.

      Remove; no longer needed.

      GNU/Linux.  Redirect file descriptor, not stream, so that the code
      works even if stderr is not an lvalue.  Report an error if the
      file arg is neither a string nor nil.
      (syms_of_print): Always define redirect-debugging-output.
