      Use SAFE_ALLOCA etc. to avoid unbounded stack allocation. · b3bf18b3

      This follows up on the recent thread in emacs-devel on alloca; see:
      http://lists.gnu.org/archive/html/emacs-devel/2014-09/msg00042.html

      * sound.c (Fplay_sound_internal):
      * xdisp.c (load_overlay_strings, dump_glyph_row):
      Use an ordinary auto buffer rather than alloca, since the
      allocation size is fixed and small.
      * ftfont.c: Include <c-strcase.h>.
      (matching_prefix): New function.
      (get_adstyle_property): Use it, to avoid need for alloca.

      (SAFE_ALLOCA_STRING): ... new macro with different API.
      This fixes a portability problem, namely, alloca result
      passed to another function.  All uses changed.
      (SAFE_ALLOCA, SAFE_ALLOCA_LISP): Check for MAX_ALLOCA,
      not MAX_ALLOCA - 1.
      * regex.c (REGEX_USE_SAFE_ALLOCA, REGEX_SAFE_FREE)
      (REGEX_ALLOCATE): New macros.
      (REGEX_REALLOCATE, REGEX_ALLOCATE_STACK, REGEX_REALLOCATE_STACK)
      (REGEX_FREE_STACK, FREE_VARIABLES, re_match_2_internal):

      Fix some fd issues when running subprocesses. · 94fcd171
      Paul Eggert authored
      Fix bugs that can leak files or file descriptors on errors.
      Don't unlink open temp files, as that's hard for users to diagnose
      when things go awry (e.g., temp disk exhausted).
      Don't bother to lock temp files.  Check for invalid recursion.
      * callproc.c (synch_process_fd): Remove.  All uses removed.
      (synch_process_tempfile): New var or macro.
      (CALLPROC_STDOUT, CALLPROC_STDERR, CALLPROC_PIPEREAD, CALLPROC_FDS):
      New constants.
      (record_kill_process): New arg, the temp name.  All callers changed.
      (delete_temp_file): Now just a simple wrapper around unlink.
      (call_process_kill): New arg, the call_process_fd array.
      Close them all.  Clear synch_process_pid.  Remove the temp file,
      or arrange for it to be removed.
      (call_process_cleanup) [MSDOS]: Arg no longer contains file name;
      that's been moved to synch_process_tempfile.  Caller changed.
      Do not remove the tempfile; that's now call_process_kill's
      responsibility.
      (call_process_cleanup) [!MSDOS]: Do not record unwind-protect for
      call_process_kill; the caller now does that.
      (call_process_cleanup): Do not close the process fd; that's now
      call_process_kill's responsibility.
      (Fcall_process): Implement via new function call_process, which
      has most of the old body of Fcall_process, but with a different API.
      (call_process): New function that does not open or close filefd if
      it is nonnegative.  Record which fds need to be closed, and let
      call_process_kill close (and remove the tempfile, on MSDOS) on error.
      Signal an error if invoked recursively (could be done via a hook).
      Simplify creation of the tempfile in the MSDOS case.
      Don't create the output file until after checking for the executable.
      Report any failure to open /dev/null.
      Don't open /dev/null for writing twice; once is enough.
      Don't create pipe if all output is being discarded or sent to file.
      Don't worry about setting up the coding system or reading from the
      pipe if all output is being discarded.
      Hoist fd_error local into top level, to lessen block nesting.
      Don't record deleted pid here; now done by Fcall_process_region.
      (Fcall_process) [MSDOS]: Report mktemp failure immediately,
      and note its success in synch_process_tempfile.
      Do not leak resources when child_setup fails.
      (Fcall_process) [!MSDOS && !WINDOWSNT]: Remove duplicate assignment
      to child_errno.  Remove unnecessary close of fd0; it's close-on-exec.
      (create_temp_file): Now returns open fd, with an additional
      Lisp_Object * argument to return the name.  All callers changed.
      Do not close the file; rewind it instead, and leave it open for
      the caller.  Do not lock the temp file.  Unwind-protect the file
      and the file-descriptor.
      (Fcall_process_region): If the input is /dev/null, unwind-protect it.
      If an asynchrounous process, record it here, not in call_process.
      (syms_of_callproc) [MSDOS]: Initialize synch_process_tempfile.
      * eval.c (set_unwind_protect): New function.
      * fileio.c (write_region): New function, generalized from the
      old Fwrite_region.  Do not lock temp files.
      (Fwrite_region): Use it.
      * lisp.h (set_unwind_protect, write_region): New decls.
      * process.c: Include <verify.h>.
      (make_process): Mark fds as initially closed.
      (deleted_pid_list): Now a list of pid-filename pairs.
      All uses changed.
      (close_process_fd): New function.
      (SUBPROCESS_STDIN, WRITE_TO_SUBPROCESS, READ_FROM_SUBPROCESS)
      (SUBPROCESS_STDOUT, READ_FROM_EXEC_MONITOR, EXEC_MONITOR_OUTPUT):
      New constants.  Verify that their number matches PROCESS_OPEN_FDS.
      (create_process, create_pty, Fmake_serial_process)
      (server_accept_connection): Record which fds need to be closed,
      and let deactivate_process close them.
      (Fmake_network_process): Do not discard the unwind-protect
      until it's safe to do so.
      (deactivate_process): Close the fds opened by create_process etc.
      (Fprocess_send_eof): Adjust to new way of recording open fds.
      Report an error if /dev/null can't be opened, instead of aborting.
      * process.h (PROCESS_OPEN_FDS): New constant.
      (struct Lisp_Process): New member open_fds.
      (record_kill_process, record_deleted_pid): Adjust signatures.
      (record_deleted_pid): Move decl here ...
      * syswait.h (record_deleted_pid): ... from here.

      Prefer list1 (X) to Fcons (X, Qnil) when building lists. · 6c6f1994
      Paul Eggert authored
      This makes the code easier to read and the executable a bit smaller.
      Do not replace all calls to Fcons that happen to create lists,
      just calls that are intended to create lists.  For example, when
      creating an alist that maps FOO to nil, use list1 (Fcons (FOO, Qnil))
      rather than list1 (list1 (FOO)) or Fcons (Fcons (FOO, Qnil), Qnil).

      In particular this ports to 32-bit sparc Sun cc.
      * eval.c (init_eval_once, grow_specpdl): Allocate a specbinding
      array with a dummy element at specpdl[-1], so that its address can
      be taken portably.
      (unbind_to): Do not copy the binding; not needed, now that we

      * fileio.c (Fwrite_region): Use ptrdiff_t, not int, for specpdl count.
      * lisp.h (BITS_PER_PTRDIFF_T): Remove; no longer needed.
      (union specbinding): Rename from struct specbinding.  Redo layout
      to avoid the need for 'ptrdiff_t nargs : BITS_PER_PTRDIFF_T - 1;',
      which is not portable.  With Sun C 5.12 32-bit sparc, the
      declaration causes nargs to be an unsigned bitfield, a behavior
      that the C standard allows; but Emacs wants nargs to be signed.
      The overall type is now a union of structures rather than a
      structure of union of structures, and the 'kind' member is now a
      bitfield, so that the overall type doesn't grow.  All uses changed.

      Use functions, not macros, for XINT etc. · 84575e67
      Paul Eggert authored
      In lisp.h, prefer functions to function-like macros, and
      constants to object-like macros, when either will do.  This:
       . simplifies use, as there's no more need to worry about
         arguments' side effects being evaluated multiple times.
       . makes the code easier to debug on some platforms.
      However, when using gcc -O0, keep using function-like macros
      for a few critical operations, for performance reasons.
      This sort of thing isn't needed with gcc -Og, but -Og
      is a GCC 4.8 feature and isn't widely-enough available yet.
      Also, move functions from lisp.h to individual modules when possible.
